Press Release of Aalto University (in Finnish)

Aalto-yliopiston semanttisen webin tutkijat voittivat World Summit Award Mobile 2010 –kilpailun SmartMuseum -järjestelmällä

Aalto-yliopiston ja kuuden muun yliopiston ja tutkimuspartnerin kehittämä SmartMuseum-järjestelmä on voittanut kansainvälisen World Summit Award Mobile 2010 palkinnon. Työ valittiin parhaaksi kategoriassa ”M-turism and Culture” 430 ehdokkaan joukosta, jotka nimitettiin lähes sadan eri valtion osakilpailuissa.

SmartMuseum -järjestelmän ideana on tarjota museossa kävijälle tietoa ja opastusta kokoelmakohteista älykkäästi ja personoidusti paikan päällä. Voittoisan pilottijärjestelmän sisällöt ovat peräisin Firenzen tieteenhistoriallista Galileo museosta ja Maltan taidemuseosta. SmartMuseum-järjestelmän älykkyys perustuu semanttisen webin teknologioihin ja -portaalin haku- ja suosittelujärjestelmiin. Sisällöntuotannossa on hyödynnetty kansallista ontologiakirjastopalvelua.

Suomen osuus tutkimus- ja kehitystyöstä tehtiin Aalto-yliopiston mediatekniikan laitoksen Semanttisen laskennan tutkimusryhmässä, joka oli lokakuussa voittoisa myös Apps4Finland – Doing Good with Open Data -kilpailussa semanttisella DataSuomi-järjestelmällä.

– Molempien palkintojen taustalla on vuodesta 2003 tutkimusryhmässämme johdettu laaja FinnONTO-hanke kansallisen semanttisen webin infrastruktuurin kehittämiseksi maahamme. Sen tutkimustuloksia ja uusia työkaluja voidaan nyt hyödyntää nopeasti ja kehittää edelleen uusissa sovelluksissa, kertoo hankkeen johtaja Eero Hyvönen.

World Summit Award on Yhdistyneiden kansakuntien ja sen Global Alliance for ICT and Development (UN GAID) -järjestön lippulaivahanke, joka järjestetään yhteistyössä UNESCO:n ja UNIDO:n kanssa. Palkinnot jaettiin Abu Dhabissa 6.12. pidetyssä kansainvälisessä WSA Mobile -gaalassa.

Friday, 26th of November: dissertation defence by Eetu Mäkelä and guest lecture by professor Lora Aroyo of Vrije Universiteit Amsterdam

Wednesday, November 10th, 2010

(väitöstiedote suomeksi)

Please be welcome to Eetu Mäkelä’s public defence of his doctoral thesis on View-Based User Interfaces for the Semantic Web. The defence will take place on Friday, the 26th of November, at 12 noon at the TUAS Building (Otaniementie 17, Espoo), Auditorium TU2. The defence will also be broadcast live over the internet here.

The content of the dissertation to be presented deals with the benefits that may be gained from publishing data using Semantic Web techniques, and how these benefits can be realized. Particular emphasis is placed on how originally varied and heterogeneous data can be linked to each other, and what new functionalities this enables for an end-user. Also discussed are how these functionalities are best implemented in user interfaces and system architecture.

The work in the thesis focuses mostly on publishing cultural heritage information in national level integrated portals. During the work two such were produced: and Of these, MuseumFinland was awarded both the Semantic Web Challenge award of the international research community as well as the Finnish prime minister’s honorary mention for the most innovative web application of the year. Other content areas discussed are e-Health, e-Government, e-Learning and e-Commerce.

As examples of the user interfaces developed during the work, data exploration interfaces were implemented that can answer questions such as “How beard fashions changed in the end of the 19th century?”, “which themes were the most popular in Finnish fiction in the year 2007?”, “what are the most popular colors of peoples’ underwear?” and “how are the Finnish painter Akseli Gallen-Kallela and the French emperor Napoleon the first connected to each other?”.

The viewpoint of an information provider is catered for in the section of the thesis discussing production and publishing architectures for Linked Open Data, as well as the problems faced in integrating vastly heterogeneous data.

The dissertation is available for download here (pdf).

Preceding the dissertation, the opponent, professor Lora Aroyo (Vrije Universiteit Amsterdam) will give a guest lecture at the same auditorium at 10:15-11:00 on “User Interaction and Personalization with Semantics”.

In this talk I will present three use cases of how the use of semantics (1) brings added value and (2) introduces new challenges for the user interaction and personalization. The main focus of this research is to investigate how knowledge patterns in Linked Open Data can help in the process of consuming semantically enriched Web content. The three use cases are explored in the context of three projects NoTube (personalized access to TV content using content patterns in Linked Open Data), CHIP (personalized access to enriched museum collections using content patterns in domain ontologies), WAISDA? (interactive tagging game to collect user-generated data and use it for annotation of audio-visual collections). I will also demonstrate some of the prototypes developed for these use cases.

Väitös maanantaina 7.6.2010 klo 12: Internetin sisältöjen käyttö helpottuu älykkäiden suosittelujärjestelmien avulla

Thursday, May 27th, 2010

Tuukka Ruotsalo väittelee maanantaina 7.6.2010 klo 12 aiheesta “Menetelmiä ja sovelluksia ontologiaperustaisiin suosittelujärjestelmiin”. Tervetuloa!

Osoite: Aalto-yliopiston teknillinen korkeakoulu, TUAS-talo, Sali AS1, Otaniementie 17, Espoo. Kartta.

Web-sisältöjen määrä kasvaa nopeasti ja vaikeuttaa olennaisen tiedon löytämistä Internetin sisältömassasta. Väitöskirjan päätuloksena on syntynyt suosittelujärjestelmiä, jotka tunnistavat käyttäjää kiinnostavat informaatiokohteet analysoimalla niiden sisältöä, jolloin sovellukset voivat tiedottaa käyttäjää kohteista, joihin käyttäjä mahdollisesti haluaisi tutustua.

Kehitetyt suosittelujärjestelmät perustuvat semanttisen webin ontologioihin ja menetelmiin, joiden avulla tietokoneet kykenevät analysoimaan sisältöjen merkityksiä ja parantavat näin suosittelun tarkkuutta. Menetelmien erityispiirteenä on, että ne mahdollistavat eri lähteistä peräisin olevien, yhteensopimattomissa muodoissa tuotettujen sisältojen suosittelun. Esimerkiksi osa tiedontuottajista kuvailee sisältöjä tekstikuvauksilla, kun taas toisen tuottajan sisällöt voivat olla saatavilla erimuotoisissa rakenteisissa tietokannoissa.

Tutkimustyö on tehty Aalto-yliopiston ja Helsingin yliopiston semanttisen laskennan tutkimusryhmässä osana FinnONTO-tutkimusohjelmaa, EU:n SmartMuseum-hanketta, sekä tutkijavaihdon yhteydessä Amsterdamissa VU-yliopistossa. Menetelmiä on käytetty kulttuurialan kansallisessa semanttisessa Kulttuurisampo portaalissa sekä mobiilin tiedonhaun tukena Smartmuseum järjestelmässä, jota on pilotoitu Firenzen Galileo Galilei -museossa (IMSS) sekä Maltan taidemuseossa.
