Towards personalization in digital libraries through ontologies

In this paper we describe a browsing and searching personalization system for digitallibraries based on the use of ontologies for describing the relationships between all theelements which take part in a digital library scenario of use. The main goal of thisproject is to help the users of a digital library to improve their experience of use bymeans of two complementary strategies: first, by maintaining a complete history recordof his or her browsing and searching activities, which is part of a navigational userprofile which includes preferences and all the aspects related to community involvement; and second, by reusing all the knowledge which has been extracted from previous usage from other users with similar profiles. This can be accomplished in terms of narrowing and focusing the search results and browsing options through the use of a recommendation system which organizes such results in the most appropriatemanner, using ontologies and concepts drawn from the semantic web field. The complete integration of the experience of use of a digital library in the learning process is also pursued. Both the usage and information organization can be also exploited to extract useful knowledge from the way users interact with a digital library, knowledge that can be used to improve several design aspects of the library, ranging from internal organization aspects to human factors and user interfaces. Although this project is still on an early development stage, it is possible to identify all the desired functionalities and requirements that are necessary to fully integrate the use of a digital library in an e-learning environment.

Ontologia de LinkedIn : El primer pas per inferir informació a partir de les ofertes de feina

Amb aquest treball de final de carrera de la titulació d'enginyeria tècnica en informàtica de gestió es pretén fer una primera aproximació al món de l'anàlisi semàntic de webs. Consisteix, per una banda, en la creació d'una ontologia per emmagatzemar informació provinent de la web de LinkedIn de manera que després pugui ser analitzada i permeti filtrar les dades de manera pràctica evitant l'excés d'informació no útil. Per altra banda, el treball inclou el desenvolupament d'una aplicació per a l'obtenció de la informació de la web de LinkedIn de manera automàtica, i un mètode per a la importació a l'ontologia creada.

Ontologia del LinkedIn : Primer pas per inferir informació a partir de les ofertes de feina

El cas que ens ocupa és la xarxa social LinkedIn. La quantitat d'ofertes i demandes de feina fan a vegades difícil extreure'n la informació necessària. Es vol crear una ontologia per tal de nodrir les dades presents en la web LinkedIn amb informació semàntica. Mitjançant el programari Protégé es pretén crear aquesta ontologia i, mitjançant les API que ofereix LinkedIn, un mitjà per inferir informació respecte a les ofertes i demandes de feina.

Service Description Creation Empowerment to Mobile End Users

Increasing usage of Web Services has been result of efforts to automate Web Services discovery and interoperability. The Semantic Web Service descriptions create basis for automatic Web Service information management tasks such as discovery and interoperability. The discussion of opportunities enabled by service descriptions have arisen in recent years. The end user has been considered only as a consumer of services and information sharing occurred from one service provider to public in service distribution. The social networking has changed the nature of services. The end user cannot be seen anymore only as service consumer, because by enabling semantically rich environment and right tools, the end user will be in the future the producer of services. This study investigates the ways to provide for end users the empowerment to create service descriptions on mobile device. Special focus is given to the changed role of the end user in service creation. In addition, the Web Services technologies are presented as well as different Semantic Web Service description approaches are compared. The main focus in the study is to investigate tools and techniques to enable service description creation and semantic information management on mobile device.

Mobiilisovellusten keskitetyt jakelukanavat

Diplomityössä tutkitaan mobiilisovellusten keskitettyjä jakelukanavia. Nämä uudet jakelukanavat ovat mahdollistaneet sovellusten uuden tyylisen ja helpon jakelun. Työssä tutkitaan itsenäisen kehittäjän näkökulmasta sovelluksen kehitystä Android-, iOS- ja Windows Phone -ohjelmistoalustoilla, ja sen julkaisua App Storessa, Google Playssa ja Windows Phone Marketplacella. Tavoitteena on tutkia huomataanko esimerkkisovelluksen kehityksessä ja julkaisussa merkittäviä eroja jakelukanavien välillä. Prosesseissa havaittiin eroja, mutta ei kuitenkaan niin merkittäviä, että jokin jakelukanava voitaisiin nostaa selkeästi toisten edelle helpompana tai rajoitteista vapaampana vaihtoehtona.

Factors Affecting Consumer Investment Intentions. Empirical Evidence from Finland

The thesis aims to build a theoretical model to explain consumer investment intentions in stocks and investment funds. The model examines the relationships between subjective investment knowledge, expected sacrifice, expected investment value, compatibility, perceived behavioral control and investment intentions. The data was collected via web-based survey and consisted of 45- to 65-year-old Finnish consumers (n=154). Confirmatory factor analysis (CFA), structural equation modeling (SEM) and t-tests were applied in analyzing the data. The results suggest that among average household consumers expected investment value consists of three dimensions, namely, economic, functional, and emotional, whereas expected sacrifice consists of effort, financial risk, source risk, and psychological risk. Two structural models were assessed, one for stock investments and one for investment funds. Whereas the models presented somewhat different outcomes, in both models compatibility had an essential role in explaining consumer investment intentions. Compatibility was affected by expected investment value and expected sacrifice. Subjective investment knowledge impacted consumers’ evaluations of the value and sacrifices. The effect of perceived behavioral control on investment intentions was rather small, however significant. Moreover, the results suggest that there are significant differences between consumers with no investment experience and consumers with investment experience in subjective investment knowledge, the dimensions of expected sacrifices and expected investment value, perceived behavioral control, compatibility and investment intentions.

Replikoitavan palvelinjärjestelmän toteuttaminen julkisen liikenteen avoimen datan jakeluun

Tässä diplomityössä tutkittiin, miten toteuttaa replikoitava palvelinjärjestelmä julkisen liikenteen avoimen datan jakeluun. Tutkimuksessa selvitettiin, onko vastaavanlaisia järjestelmiä suunniteltu aiemmin, vai pitääkö järjestelmä suunnitella itse. Projektissa käytettiin avoimen lähdekoodin OneBusAway-ohjelmistokokonaisuutta. Projektin avulla osoitettiin, että kyseinen ohjelmisto toimi yliopiston testikäytössä hyvin. Ohjelmiston avulla pystytään jakelemaan staattista ja reaaliaikaista dataa, ja se on replikoitavissa kunnasta toiseen maailmanlaajuisesti. Tulevaisuudessa olisi kuitenkin hyvä selvittää, miten ohjelmistosta puuttuva reittihakuominaisuus kannattaisi toteuttaa, sekä olisiko REST- rajapinta mahdollista muuttaa sellaiseksi, että se noudattaisi julkisen liikenteen standardeja.
