ESWC 2007, Innsbruck 3 -7 June, 2007 see http: //eswc 2007. org

Conference Profile • Chairs: E. Franconi (U. Bolzano, IT), M. Kifer (SUNY, USA), W. May (U. Göttingen, DE) • About 300 registered participants (2 from CZ) • 278 papers (54% growth vs. 2006!) submitted • 46 (18%) accepted as full papers, 10 as system descriptions and 37 as posters • 4 invited talks: Stefano Ceri, Ning Zhong, Georg Gottlob, Ron Brachman • 7 workshops, 7 tutorials • Ph. D symposium • Collocated events (OWLED, RR, DL workshop - Bolzano)

Invited talks • Stefano Ceri (Polit. Milano, IT): Design Abstractions for Innovative Web Applications: the case of the SOA augmented with Semantics • Ning Zhong (Maebashi Institute of Technology, JP): Ways to Develop Human-Level Web Intelligence: A Brain Informatics Perspective • Georg Gottlob (U. Oxford, UK): The Lixto systems applications in Business Intelligence and Semantic Web • Ron Brachman (Yahoo!): Emerging Sciences of the Internet: Some New Opportunities

Topics of Papers • Not much strikingly new, but mostly solid quality research • Often combination of ontological engineering, text mining, RDF querying… • Lot of logics, e. g. reasoning benchmarks, measuring ontology inconsistency, new approaches in applying DL, ASP, fuzzy logics… • Web services – dominated by WSMO • Impact of Web 2. 0 (wikis, folksonomies, AJAX…) • Still somewhat dominated by people from projects such as Knowledge Web or SEKT (about 50% of papers)

Some presentations I • Witte, Zhang, Riling – Software code analysis plus (docs) text mining to help software maintenance • Hepp, de Bruijn – Building ontologies from thesauri&taxonomies • Kochut, Janik – RDF path patterns in Spa. RQL-like querying • Oren, Gerke, Decker – Suggesting RDF predicates for semantic wikis based on similarity of resources and co-occurrence of predicates

Some presentations II • Völker, Vrandečić, Sure, Hotho – Learning disjointness of concepts (from labelled data) based on variety of features: taxonomy, logics, Hearst. . . • van Atteveldt, Schlobach, van Harmelen – Evaluation of different methods of enriching RDF triples in the context of news media content analysis • Aleman-Meza, Bojārs, Boley, Breslin, Mochol, Nixon, Polleres, Zhdanova – Combining RDF vocabularies (FOAF, SIOC, SKOS, DOAP, DOAC, v. Card, i. Cal, Bib. Te. X, …) for expert finding • Kings, Gale, Davies – Squidz: tool (IE plug-in) for automated page classification plus social bookmarking

Some presentations III • Duke, Glover, Davies – Squirrel: search tool based on balanced keyword- and semantics-based querying • Vrandečić, Sure – Metrics for ontology evaluation (based on normalisation) • Deng Xi, Haarslev V. – Quantitative measure for measuring inconsistency in ontologies • Suominen, Viljanen, Hyvönen – Designing facets for searching a portal using ‘card sort’

Some presentations IV • Ragone A. , Straccia U. et al. – Fuzzy logic for modelling specification as soft constraints • Sazedj P. , Pinto S. – Verb-based extraction, extraction of relation (ontology population) • Auer, Lehmann – Extraction of facts from semi-structured info (templates) in Wikipedia – aka table extraction • Groza, Handschuh, Möller, Decker – Annotations of paper claims etc. in La. Te. X, by authors, then stored inside PDF

Some presentations V • Schroeter, Hunter, Newman – Version of Annotea for annotating multimedia (e. g. sports videos!); focus on RDF issues, e. g. linking segments of objects • Immaneni, Thirunarayan – Hybrid querying to HTML web and semantic web using a unified data model • Kiefer, Bernstein, Lee, Klein, Stocker – Imprecise Spa. RQL, application on process descriptions • Specia, Motta – Upgrading folksonomies (del. icio. us, Flickr): clustering, cooccurrence, finding associations via Swoogle

Some presentations VI • Šváb, Svátek, Stuckenschmidt – Posterior evaluation of ontology mapping results using IR measures, ‘consensus workshop’ discussion, distributed description logic and LISp-Miner • Völker, Hitzler, Cimiano – Learning DL axioms from definitions (Wikipedia, FAO fishery) • Poster about the Watson tool (d’Aquin…) – Like Swoogle but focus on ontology quality filtering and online combination

But not only the conference had very high level…

ESWC 2008 • Organised by UP Madrid (Asun Gomez-Perez) • Tenerife, Canary Islands
