    The goal of the thesis study was to create a culture travel concept based on the Finnish-Karelian mythology and the national epic Kalevala. The Kalevala kartalle -project was a pilot to evaluate and demonstrate the concept for Japanese tourists during 01/2020-12/2021. The Stefan Moritz ́s service design model was utilized as the methodology to conduct the product-oriented thesis. Cultural heritage raises emotions and opinions how to utilize it. Although the mutual opinion is, that traditions and immaterial heritage are everyone ́s right and at everyone ́s responsibility, the praxis seems more complicated than that. The tourism industry has developed travel and leisure experiences inspired by cultural elements, stories, and myths. Nevertheless, the Finnish folklore is not widely known among international tourists. Stories are an impactful means to engage, educate and immerse the audience during the travel. Cultural routes demonstrate a journey through time and space; the heritage of a country and its culture contributes to a living and shared cultural heritage. The concept of the travel route was developed in co-operation with stakeholders from the public and private sector and other relevant organizations. Two pilot groups were created: one in the capital region of Finland and the other one in the region of Kainuu. These destinations created the touch points of the route, from Helsinki ending to Kuhmo city. The outcome of the pilot project was the concept of the Kalevala kartalle -culture travel route, digitally and on-site. Two seminars were organized with Visit Finland, a digital trip was produced and piloted for Japanese travellers and the concept launch was organized for the Finnish audience. The Kalevala kartalle -project gained a lot of attention in the media and was raised to the public discussion in March 2021. The IPR conflict with Kalevala Koru Oy underlines the importance and relevancy of mutual understanding of the use of cultural heritage in a commercial context. The development of new services with an ecosystem of stakeholders requires continuous work and financing. The conclusion of the pilot project is that the Japanese market has an interest in travel experiences combining the learning aspect of local culture and nature activities.

    The goal of this thesis was to examine how collaborative projects can be used to facilitate communication and storytelling between generations. Encouraging and developing cross-generationally interactive activities have become increasingly relevant as family structures change and generations diverge. Continually improving and finding new approaches ensures that family heritage and legacies continue to be communicated. Art has been used as a documentational and communicative tool for centuries. The research presented in this thesis shows that collaborative art can incite valuable intergenerational communication and that intergenerationally interactive projects have the potential to preserve familial legacies and cultural heritage, as well as improve general well-being. A combination of elements from analysed artworks and findings on intergenerational legacy work was exhibited in the thesis project Golden Places (2022). Golden Places is a four-part artwork made together with the artist’s grandparents. The working process and outcomes are presented in the form of a case study. The case study demonstrates that collaborative art can be used to bond the grandchild and grandparent and successfully produce art that embodies family stories and legacy. This thesis, specifically Golden Places, is intended to motivate and instruct others to partake in similar projects.

    Understanding linear perspective is a fundamental skill when the goal is to create the illusion of depth on a flat surface. This requires a lot of analytical thinking, spatial awareness, and good hand-eye coordination. The learning process can feel very technical and distant from the concept of figurative art, and this is one of the main reasons students skip the fundamentals, only to come back later after realizing how important it is. This thesis goes through the basic principles of linear perspective which form the basis for the presented constructive drawing method. Learning to visualize the three-dimensional nature of objects is at the core of this method. The purpose of this thesis was to demonstrate the importance of understanding linear perspective as a part of the creative process when drawing human figures. The focus was to show how to constructively draw the fundamental framework of human figures rather than create detailed and fully rendered artwork. The findings indicated that the tools and methods presented in this thesis can help to create an efficient and progressive learning process. Students and professionals involved with representational drawing can use this thesis as a guideline for the study of drawing human figures in perspective.

    This thesis will describe the Great Bell Temple's desire to promote tourism at the Great Bell Temple Museum by designing and selling souvenirs with unique cultural significance, and to attract more visitors to the temple through popular cultural and creative products. A cultural tourism product can be defined as anything that is based on cultural tourism resources and is offered to tourists participating in cultural tourism to satisfy their cultural needs and desires. The question around whether tourism souvenirs can promote tourism in Great Bell Temple. This thesis studies the history of tourist souvenirs, development trends, the development of tourist souvenirs in China, the situation of the Great Bell Temple itself and the development of tourist souvenirs in the Forbidden City. The thesis uses a quantitative survey, using a questionnaire tool for data collection, to draw conclusions. This quantitative study concludes that tourism can be promoted when the design features of tourism souvenirs include a unique culture, are cost effective, have adequate promotion and marketing methods, and have commemorative and collectible value.

    Ancient DNA research has become a widely applied method to examine past communities. The acidic soil in Finland has previously complicated archaeogenetic research but advances in the field have opened up new opportunities in recent years. This thesis integrates genetic data and archival research to examine the genetic ancestry and social organisation of Early Medieval communities in Southwest Finland. In this era, the coastal region of Southwest Finland experienced diverse societal changes induced by trade networks, urbanisation and conversion to Christianity. These shifts can be observed in large inhumation burial grounds from the Crusade Period (1025/1050–1150/1200 CE). While the burial grounds contain well-preserved skeletal material, no prior ancient DNA investigations have been undertaken in the area. A total of 30 individuals from three burial grounds, Tuomala, Kansakoulunmäki and Humikkala, were studied. The sites are located in the historical Raisio and Masku parishes close to Raisio river valley. The burial context was reconstructed with archival research, and the genetic data was extracted from skeletal samples. The resulting genome-wide data for 8 individuals from the Kansakoulunmäki burial ground was studied with exploratory population genetic and kinship analyses. The archival research produced a detailed burial context for 14 individuals from Kansakoulunmäki in Raisio and 15 individuals from Humikkala in Masku. The genetic results concluded good molecular preservation at Kansakoulunmäki and poor at Tuomala and Humikkala. The Kansakoulunmäki and Humikkala individuals bore traces of diverse connections to the Baltic Sea region. The integrated results revealed possible evidence of patrilocality and potential female genetic connections to Sigtuna in Central Sweden. These findings may point towards female mobility or exogamous marriage patterns between the two regions. Kinship relations were also detected. The possible sibling relationship could indicate an Early Medieval burial practice where close kin was buried together. The Kansakoulunmäki individuals appeared local and displayed genetic continuity with present-day Finns. This thesis adds to an emerging body of research on the ancient genetic compositions and social practices in coastal Southwest Finland in a period of transformation. The results underline the potential of interdisciplinary strategies combining genetic and archival research, as well as possibilities in the investigation of larger inhumation burial grounds. The study contributes to diverse lines of research with new data and interpretations about the Early Medieval communities, suggesting potential for further analyses both in Finland and across the Baltic Sea region.

    Alati enemmän aineistoa tuotetaan ja jaetaan internetin kautta. Aineistot ovat vaihtelevia muodoiltaan, kuten verkkoartikkelien ja sosiaalisen media julkaisujen kaltaiset digitaaliset tekstit, ja niillä on usein spatiaalinen ulottuvuus. Teksteissä geospatiaalisuutta ilmaistaan paikannimien kautta, mutta tavanomaisilla paikkatietomenetelmillä ei kyetä käsittelemään tietoa epätäsmällisessä kielellisessä asussaan. Tämä on luonut tarpeen muuntaa tekstimuotoisen sijaintitiedon näkyvään muotoon, koordinaateiksi. Ongelmaa ratkaisemaan on kehitetty geojäsentimiä, jotka tunnistavat ja paikantavat paikannimet vapaista teksteistä, ja jotka oikein toimiessaan voisivat toimia paikkatiedon lähteenä maantieteellisessä tutkimuksessa. Geojäsentämistä onkin sovellettu katastrofihallinnasta kirjallisuudentutkimukseen. Merkittävässä osassa geojäsentämisen tutkimusta tutkimusaineiston kielenä on ollut englanti ja geojäsentimetkin ovat kielikohtaisia – tämä jättää pimentoon paitsi geojäsentimien kehitykseen vaikuttavat havainnot pienemmistä kielistä myös kyseisten kielten puhujien näkemykset. Maisterintutkielmassani pyrin vastaamaan kolmeen tutkimuskysymykseen: Mitkä ovat edistyneimmät geojäsentämismenetelmät? Mitkä kielelliset ja maantieteelliset monitulkintaisuudet vaikeuttavat tämän monitahoisen ongelman ratkaisua? Ja miten arvioida geojäsentimien luotettavuutta ja käytettävyyttä? Tutkielman soveltavassa osuudessa esittelen Fingerin, geojäsentimen suomen kielelle, ja kuvaan sen kehitystä sekä suorituskyvyn arviointia. Arviointia varten loin kaksi testiaineistoa, joista toinen koostuu Twitter-julkaisuista ja toinen uutisartikkeleista. Finger-geojäsennin, testiaineistot ja relevantit ohjelmakoodit jaetaan avoimesti. Geojäsentäminen voidaan jakaa kahteen alitehtävään: paikannimien tunnistamiseen tekstivirrasta ja paikannimien ratkaisemiseen oikeaan koordinaattipisteeseen mahdollisesti useasta kandidaatista. Molemmissa vaiheissa uusimmat metodit nojaavat syväoppimismalleihin ja -menetelmiin, joiden syötteinä ovat sanaupotusten kaltaiset vektorit. Geojäsentimien suoriutumista testataan aineistoilla, joissa paikannimet ja niiden koordinaatit tiedetään. Mittatikkuna tunnistamisessa on vastaavuus ja ratkaisemisessa etäisyys oikeasta sijainnista. Finger käyttää paikannimitunnistinta, joka hyödyntää suomenkielistä BERT-kielimallia, ja suoraviivaista tietokantahakua paikannimien ratkaisemiseen. Ohjelmisto tuottaa taulukkomuotoiseksi jäsenneltyä paikkatietoa, joka sisältää syötetekstit ja niistä mahdollisesti tunnistetut paikannimet koordinaattisijainteineen. Testiaineistot eroavat aihepiireiltään, mutta Finger suoriutuu niillä likipitäen samoin, ja suoriutuu englanninkielisillä aineistoilla tehtyihin arviointeihin suhteutettuna kelvollisesti. Virheanalyysi paljastaa useita virhelähteitä, jotka johtuvat kielten tai maantieteellisen todellisuuden luontaisesta epäselvyydestä tai ovat prosessoinnin aiheuttamia, kuten perusmuotoistamisvirheet. Kaikkia osia Fingerissä voidaan parantaa, muun muassa kehittämällä kielellistä käsittelyä pidemmälle ja luomalla kattavampia testiaineistoja. Samoin tulevaisuuden geojäsentimien tulee kyetä käsittelemään monimutkaisempia kielellisiä ja maantieteellisiä kuvaustapoja kuin pelkät paikannimet ja koordinaattipisteet. Finger ei nykymuodossaan tuota valmista paikkatietoa, jota kannattaisi kritiikittä käyttää. Se on kuitenkin lupaava ensiaskel suomen kielen geojäsentimille ja astinlauta vastaisuuden soveltavalle tutkimukselle. Ever more data is available and shared through the internet. The big data masses often have a spatial dimension and can take many forms, one of which are digital texts, such as articles or social media posts. The geospatial links in these texts are made through place names, also called toponyms, but traditional GIS methods are unable to deal with the fuzzy linguistic information. This creates the need to transform the linguistic location information to an explicit coordinate form. Several geoparsers have been developed to recognize and locate toponyms in free-form texts: the task of these systems is to be a reliable source of location information. Geoparsers have been applied to topics ranging from disaster management to literary studies. Major language of study in geoparser research has been English and geoparsers tend to be language-specific, which threatens to leave the experiences provided by studying and expressed in smaller languages unexplored. This thesis seeks to answer three research questions related to geoparsing: What are the most advanced geoparsing methods? What linguistic and geographical features complicate this multi-faceted problem? And how to evaluate the reliability and usability of geoparsers? The major contributions of this work are an open-source geoparser for Finnish texts, Finger, and two test datasets, or corpora, for testing Finnish geoparsers. One of the datasets consists of tweets and the other of news articles. All of these resources, including the relevant code for acquiring the test data and evaluating the geoparser, are shared openly. Geoparsing can be divided into two sub-tasks: recognizing toponyms amid text flows and resolving them to the correct coordinate location. Both tasks have seen a recent turn to deep learning methods and models, where the input texts are encoded as, for example, word embeddings. Geoparsers are evaluated against gold standard datasets where toponyms and their coordinates are marked. Performance is measured on equivalence and distance-based metrics for toponym recognition and resolution respectively. Finger uses a toponym recognition classifier built on a Finnish BERT model and a simple gazetteer query to resolve the toponyms to coordinate points. The program outputs structured geodata, with input texts and the recognized toponyms and coordinate locations. While the datasets represent different text types in terms of formality and topics, there is little difference in performance when evaluating Finger against them. The overall performance is comparable to the performance of geoparsers of English texts. Error analysis reveals multiple error sources, caused either by the inherent ambiguousness of the studied language and the geographical world or are caused by the processing itself, for example by the lemmatizer. Finger can be improved in multiple ways, such as refining how it analyzes texts and creating more comprehensive evaluation datasets. Similarly, the geoparsing task should move towards more complex linguistic and geographical descriptions than just toponyms and coordinate points. Finger is not, in its current state, a ready source of geodata. However, the system has potential to be the first step for geoparsers for Finnish and it can be a steppingstone for future applied research.

    This thesis focused on the issues of gender inequality in the Greek art field. The issues of gender inequality are visible throughout the history of art not just Greek but global due to the immense effect that Greek culture has had upon the development of Western civilization and its values through its Hellenic expansion. Hence, these societal issues are not just limited to Greece but are ubiquitous in the majority of the world. The repression of women and patriarchal hegemony are in need of attention in order to evoke changes to our future society. The thesis investigates the causes of inequality, looks at art history through a contemporary gender focused lens, discusses the importance of gender equality and establishes working methods that lead to progression and alteration of archaic values. The research methods chosen are analysis and of professional literature like books and articles relevant to the topic and semiotic analysis. The languages of sources used are English, French, German, Russian, Ukrainian and some limited sources in Greek. This thesis additionally contains a discussion and evaluation of its practical part. It is a creative project based on the researched topic and is titled “Story of a Maiden”. Its discussion serves further to consolidate the importance of women in the society as well as bring attention to how historically underappreciated the women of Greece have been. It utilises the form of performance that has been prior proven to be an effective method in both actionism and activism.

    Automatic headline generation has the potential to significantly assist editors charged with head- lining articles. Approaches to automation in the headlining process can range from tools as creative aids, to complete end to end automation. The latter is difficult to achieve as journalistic require- ments imposed on headlines must be met with little room for error, with the requirements depending on the news brand in question. This thesis investigates automatic headline generation in the context of the Finnish newsroom. The primary question I seek to answer is how well the current state of text generation using deep neural language models can be applied to the headlining process in Finnish news media. To answer this, I have implemented and pre-trained a Finnish generative language model based on the Transformer architecture. I have fine-tuned this language model for headline generation as autoregression of headlines conditioned on the article text. I have designed and implemented a variation of the Diverse Beam Search algorithm, with additional parameters, to perform the headline generation in order to generate a diverse set of headlines for a given text. The evaluation of the generative capabilities of this system was done with real world usage in mind. I asked domain-experts in headlining to evaluate a generated set of text-headline pairs. The task was to accept or reject the individual headlines in key criteria. The responses of this survey were then quantitatively and qualitatively analyzed. Based on the analysis and feedback, this model can already be useful as a creative aid in the newsroom despite being far from ready for automation. I have identified concrete improvement directions based on the most common types of errors, and this provides interesting future work.

    “Mother and Son” portrays the relationship between the photographer Kasper Dalkarl and his mother. It’s a collaboration between the two, consisting of staged and semi-staged photographs pictured in places personally meaningful to the photographer, or to them both. In 2015 my father died, an event that in many ways changed the dynamic in the relationship with my mother. The shared experience of losing a close family member brought us closer together, and, over time, an equal and mutually supporting bond was formed in contrast to the traditional relationship between the parent and the child. Herein lies what the series aims to explore – the portrayal of the relationship between mother and son. With the aid of photography, this Master’s Thesis aims to not only explore and show a relationship between a mother and a son, but also to relate it to how mothers and their adult children have been portrayed throughout art history as well as by other contemporary artists. With this project I wanted to focus on what I have, rather than on what I have lost. In short, this body of work was made by me, for me and for my mother, in what became a personal series of images. kasperdalkarl.com

    The changes in the labor market accompanied by digitalization have influenced the approaches used for recruitment purposes. The development of machine learning and, specifically, natural language processing allowed new services for automated resume screening to appear. These services aim to reduce the time that HR specialists dedicate to sorting out unsuitable candidates, thus saving the costs per hire. This master thesis provides an analysis of the possible approach for matching CVs to JDs based on the taxonomy of competencies. In the literature review, there are the description and comparison of the different ontologies and taxonomies, and the analysis of the previous research performed in vacancy–CV matching provided. In the methodology part, there are the concepts of natural language processing and information extraction described, and the Sentence Transformer model and named entity recognition explained. Besides, evaluation approaches for taxonomy enrichment and vacancy–CV matching are suggested. In the solution development part, the described concepts and models are applied to the JDs and CVs data to perform taxonomy enrichment and matching tasks. The assessment of the matching algorithm performance based on the expert’s evaluation is presented. Based on the results obtained, the potential usage of the research and possible limitations are discussed.

Arviointia varten loin kaksi testiaineistoa, joista toinen koostuu Twitter-julkaisuista ja toinen uutisartikkeleista. Finger-geojäsennin, testiaineistot ja relevantit ohjelmakoodit jaetaan avoimesti.

Kaikkia osia Fingerissä voidaan parantaa, muun muassa kehittämällä kielellistä käsittelyä pidemmälle ja luomalla kattavampia testiaineistoja. Samoin tulevaisuuden geojäsentimien tulee kyetä käsittelemään monimutkaisempia kielellisiä ja maantieteellisiä kuvaustapoja kuin pelkät paikannimet ja koordinaattipisteet. Finger ei nykymuodossaan tuota valmista paikkatietoa, jota kannattaisi kritiikittä käyttää. Se on kuitenkin lupaava ensiaskel suomen kielen geojäsentimille ja astinlauta vastaisuuden soveltavalle tutkimukselle. Ever more data is available and shared through the internet. The big data masses often have a spatial dimension and can take many forms, one of which are digital texts, such as articles or social media posts. The geospatial links in these texts are made through place names, also called toponyms, but traditional GIS methods are unable to deal with the fuzzy linguistic information. This creates the need to transform the linguistic location information to an explicit coordinate form. Several geoparsers have been developed to recognize and locate toponyms in free-form texts: the task of these systems is to be a reliable source of location information. Geoparsers have been applied to topics ranging from disaster management to literary studies. Major language of study in geoparser research has been English and geoparsers tend to be language-specific, which threatens to leave the experiences provided by studying and expressed in smaller languages unexplored. This thesis seeks to answer three research questions related to geoparsing: What are the most advanced geoparsing methods? What linguistic and geographical features complicate this multi-faceted problem? And how to evaluate the reliability and usability of geoparsers? The major contributions of this work are an open-source geoparser for Finnish texts, Finger, and two test datasets, or corpora, for testing Finnish geoparsers. One of the datasets consists of tweets and the other of news articles. All of these resources, including the relevant code for acquiring the test data and evaluating the geoparser, are shared openly. Geoparsing can be divided into two sub-tasks: recognizing toponyms amid text flows and resolving them to the correct coordinate location. Both tasks have seen a recent turn to deep learning methods and models, where the input texts are encoded as, for example, word embeddings. Geoparsers are evaluated against gold standard datasets where toponyms and their coordinates are marked. Performance is measured on equivalence and distance-based metrics for toponym recognition and resolution respectively. Finger uses a toponym recognition classifier built on a Finnish BERT model and a simple gazetteer query to resolve the toponyms to coordinate points. The program outputs structured geodata, with input texts and the recognized toponyms and coordinate locations. While the datasets represent different text types in terms of formality and topics, there is little difference in performance when evaluating Finger against them. The overall performance is comparable to the performance of geoparsers of English texts. Error analysis reveals multiple error sources, caused either by the inherent ambiguousness of the studied language and the geographical world or are caused by the processing itself, for example by the lemmatizer. Finger can be improved in multiple ways, such as refining how it analyzes texts and creating more comprehensive evaluation datasets. Similarly, the geoparsing task should move towards more complex linguistic and geographical descriptions than just toponyms and coordinate points. Finger is not, in its current state, a ready source of geodata. However, the system has potential to be the first step for geoparsers for Finnish and it can be a steppingstone for future applied research.

    This thesis focused on the issues of gender inequality in the Greek art field. The issues of gender inequality are visible throughout the history of art not just Greek but global due to the immense effect that Greek culture has had upon the development of Western civilization and its values through its Hellenic expansion. Hence, these societal issues are not just limited to Greece but are ubiquitous in the majority of the world. The repression of women and patriarchal hegemony are in need of attention in order to evoke changes to our future society. The thesis investigates the causes of inequality, looks at art history through a contemporary gender focused lens, discusses the importance of gender equality and establishes working methods that lead to progression and alteration of archaic values. The research methods chosen are analysis and of professional literature like books and articles relevant to the topic and semiotic analysis. The languages of sources used are English, French, German, Russian, Ukrainian and some limited sources in Greek. This thesis additionally contains a discussion and evaluation of its practical part. It is a creative project based on the researched topic and is titled “Story of a Maiden”. Its discussion serves further to consolidate the importance of women in the society as well as bring attention to how historically underappreciated the women of Greece have been. It utilises the form of performance that has been prior proven to be an effective method in both actionism and activism.

    Automatic headline generation has the potential to significantly assist editors charged with head- lining articles. Approaches to automation in the headlining process can range from tools as creative aids, to complete end to end automation. The latter is difficult to achieve as journalistic require- ments imposed on headlines must be met with little room for error, with the requirements depending on the news brand in question. This thesis investigates automatic headline generation in the context of the Finnish newsroom. The primary question I seek to answer is how well the current state of text generation using deep neural language models can be applied to the headlining process in Finnish news media. To answer this, I have implemented and pre-trained a Finnish generative language model based on the Transformer architecture. I have fine-tuned this language model for headline generation as autoregression of headlines conditioned on the article text. I have designed and implemented a variation of the Diverse Beam Search algorithm, with additional parameters, to perform the headline generation in order to generate a diverse set of headlines for a given text. The evaluation of the generative capabilities of this system was done with real world usage in mind. I asked domain-experts in headlining to evaluate a generated set of text-headline pairs. The task was to accept or reject the individual headlines in key criteria. The responses of this survey were then quantitatively and qualitatively analyzed. Based on the analysis and feedback, this model can already be useful as a creative aid in the newsroom despite being far from ready for automation. I have identified concrete improvement directions based on the most common types of errors, and this provides interesting future work.

    “Mother and Son” portrays the relationship between the photographer Kasper Dalkarl and his mother. It’s a collaboration between the two, consisting of staged and semi-staged photographs pictured in places personally meaningful to the photographer, or to them both. In 2015 my father died, an event that in many ways changed the dynamic in the relationship with my mother. The shared experience of losing a close family member brought us closer together, and, over time, an equal and mutually supporting bond was formed in contrast to the traditional relationship between the parent and the child. Herein lies what the series aims to explore – the portrayal of the relationship between mother and son. With the aid of photography, this Master’s Thesis aims to not only explore and show a relationship between a mother and a son, but also to relate it to how mothers and their adult children have been portrayed throughout art history as well as by other contemporary artists. With this project I wanted to focus on what I have, rather than on what I have lost. In short, this body of work was made by me, for me and for my mother, in what became a personal series of images. kasperdalkarl.com

    The changes in the labor market accompanied by digitalization have influenced the approaches used for recruitment purposes. The development of machine learning and, specifically, natural language processing allowed new services for automated resume screening to appear. These services aim to reduce the time that HR specialists dedicate to sorting out unsuitable candidates, thus saving the costs per hire. This master thesis provides an analysis of the possible approach for matching CVs to JDs based on the taxonomy of competencies. In the literature review, there are the description and comparison of the different ontologies and taxonomies, and the analysis of the previous research performed in vacancy–CV matching provided. In the methodology part, there are the concepts of natural language processing and information extraction described, and the Sentence Transformer model and named entity recognition explained. Besides, evaluation approaches for taxonomy enrichment and vacancy–CV matching are suggested. In the solution development part, the described concepts and models are applied to the JDs and CVs data to perform taxonomy enrichment and matching tasks. The assessment of the matching algorithm performance based on the expert’s evaluation is presented. Based on the results obtained, the potential usage of the research and possible limitations are discussed.
