1st DBpedia Community Meeting – Amsterdam 2014

VU Amsterdam

Basic Plans

Twitter : #DBpediaAmsterdam

The DBpedia Project in 2014: from a hosted data set to a public data infrastructure for the Web of Data. As the DBpedia community has grown extensively, we think that the time has come to get everybody in one large room and meet. We hope to get together three major groups involved in DBpedia: the DBpedia developers and maintainers, the communities of the individual DBpedia language chapters, and, of course, the DBpedia users. The meeting will be held at VU Amsterdam on Jan 30th and is co-located with the PiLOD 2.0 meeting one day earlier. The first session will be a discussion about the DBpedia State-of-Play, where core members of the DBpedia community present certain aspects of DBpedia and the audience is invited to give feedback and ask questions. The second session will be dedicated to users of DBpedia. We would like to invite companies, organisations, and other project to briefly present their use cases for DBpedia and give input on how we can improve DBpedia for users. Free slots still available, apply here.

After the lunch, we plan to have three break-out sessions for the topics (1) DBpedia and Library, (2) Linking text to LOD entities, and (3) What is wrong with DBpedia? Developers discussion on how to improve our baby. Finally, the last parallel sessions are planned as: DBpedia tutorial, DBpedia I18N developers’ session, and a Local Dutch DBpedia Chapter Meeting, with the additional possibility to continue break out sessions.

About DBpedia

(Source: Semantic Web Journal article)
The DBpedia community project extracts structured, multilingual knowledge from Wikipedia and makes it freely available using Semantic Web and Linked Data standards. The extracted knowledge, comprising more than 1.8 billion facts, is structured according to an ontology maintained by the community. The knowledge is obtained from different Wikipedia language editions, thus covering more than 100 languages, and mapped to the community ontology. The resulting data sets are linked to more than 30 other data sets in the Linked Open Data (LOD) cloud. The DBpedia project was started in 2006 and has since attracted large interest in research and practice. A central part of the LOD cloud, it serves as a connection hub for other data sets. For the research community, DBpedia provides a testbed serving real world data spanning many domains and languages. Due to the continuous growth of Wikipedia, DBpedia also provides an increasing added value for data acquisition, re-use, and integration tasks within organisations. In this system report, we give an overview over the DBpedia community project, including its architecture, technical implementation, maintenance, internationalisation, and usage statistics, and showcase some popular DBpedia applications.

Travel Grants / Sponsorship

Some of the DBpedia developers work on DBpedia in their free-time and will not have institutional funding to come to the meeting. Therefore, we are still looking for sponsors for travel grants (as well as coffee and food for the sessions). If you are interested in sponsoring this meeting, please email our sponsorship chair to request more information.

Participants can apply for a travel grant by filling out a form or emailing Sebastian (who will fill out the same form on your behalf 😉 ). Assuming we acquire a sponsor, these grants will be awarded depending on community activity (i.e., Google Summer of Code participation, Git Commits to DBpedia framework, activity on the mailing lists, etc.) and standing.

DBpedia hosting & usage statistics by Patrick van Kleef from OpenLink Software (see video)
Wikidata and DBpedia, Gerard Meijssen from Wikidata. So far Wikidata and DBpedia have been rather stand offish, even though they have so much in common. What I want to do is present the current state of Wikidata and indicate its challenges. Many of these challenges have been met by DBpedia. I want to discuss how the two projects can mutually benefit from their activities. (see video)

DBpedia-based applications developed from the DBpedia Greek chapter, Charalampos Bratsas, from the Greek DBpedia and OKF Greece (see video)
Bridging the Gap between DBpedia and Natural Language, Christina Unger from CITEC – Lately we released the first version of a lexicon that captures linguistically rich information about verbalizations of 354 DBpedia classes and the 300 most frequent DBpedia properties in English (soon also Spanish and German). Such a lexicon can prove useful for a wide range of NLP applications over DBpedia. However, in order to keep the construction, extension and maintenance of such a multilingual lexicon feasible, it is necessary to include the DBpedia community in crowd-sourcing lexicalizations. We would like to discuss ways to do this and show possible benefits. (see video)
