Abstract: The talk will present UBY, a large-scale resource integration
project based on the Lexical Markup Framework (LMF, ISO 24613:2008).
Currently, nine lexicons in two languages (English and German) have been
integrated: WordNet, GermaNet, FrameNet, VerbNet, Wikipedia (DE/EN),
Wiktionary (DE/EN), and OmegaWiki. All resources have been mapped to the
LMF-based model and imported into an SQL-DB. The UBY-API, a common Java
software library, provides access to all data in the database. The nine
lexicons are densely interlinked using monolingual and cross-lingual sense
alignments. These sense alignments yield enriched sense representations
and increased coverage. A sense alignment framework has been developed for
automatically aligning any pair of resources mono- or cross-lingually. As
an example, the talk will report on the automatic alignment of WordNet and
Wiktionary. Further information on UBY and UBY-API is available at:

Bio: Iryna Gurevych leads the UKP Lab in the Department of Computer
Science of the Technische Universit├Ąt Darmstadt (UKP-TUDA) and at the
Institute for Educational Research and Educational Information (UKP-DIPF)
in Frankfurt. She holds an endowed Lichtenberg-Chair "Ubiquitous Knowledge
Processing" of the Volkswagen Foundation. Her research in NLP primarily concerns applied lexical semantic algorithms, such as computing semantic relatedness of words or paraphrase recognition, and their use to enhance the performance of NLP tasks, such as information retrieval, question answering, or summarization
