Mapping the Lexicons of Signs and Words
(Joint work with Colin Lualdi and Jack Hudson) We discuss the mapping of two on-line dictionaries, the Princeton WordNet and SignStudy, a resource for American Sign Language (Lualdi, Hudson & Corden 2014). The alignment has immediate benefits for first and second language acquisition within and across language modalities. Significantly, the mapping will make SignStudy’s contents accessible to the worldwide community of WordNet users and will raise awareness and promote understanding of sign language. We will address numerous challenging questions, including to what extent the WordNet-style organization of the English lexicon is applicable to ASL, and how to represent and encode additional, modality-specific relations among signs.
Christiane Fellbaum earned a Ph.D. in linguistics and is a Lecturer with
Rank of Professor at Princeton University in the Program in Linguistics
and the Department of Computer Science. Her research interests include
lexical semantics, the syntax-semantics interface, computational
linguistics and lexicography as well as psycholinguistics. She is a
co-developer of the WordNet database and has been active in WordNet
construction in many languages.

Schema.org Annotations and Web Tables: Underexploited Semantic Nuggets on the Web?
Millions of websites have started to annotate data describing products, local business, events, jobs, places, recipes, and reviews within their HTML pages using the schema.org vocabulary. These annotations are widely used by search engines to render rich snippets within search results. Surprisingly, the annotations are hardly used by the research community. In the talk, Christian Bizer investigates the potential of schema.org annotations for being used as training data for tasks such as entity matching, information extraction, and sentiment analysis. Web pages that offer semantic annotations often also contain additional structured data in the form of HTML tables. In the second part of the talk, Christian Bizer discusses the interplay of semantic annotations and web tables for information extraction as well as the general potential of relational HTML tables for complementing knowledge bases such as DBpedia, focusing on the discovery of formerly unknown long tail entities as well as the extraction of n-ary relations.
Christian Bizer explores technical and empirical questions concerning the development of global, decentralized information environments. His current research focus is the evolution of the World Wide Web from a medium for the publication of documents into a global dataspace. Christian Bizer initialized the W3C Linking Open Data, he co-founded the DBpedia project, and is engaged in the WebDataCommons project which monitors the adoption of schema.org, RDFa, Microdata, JSON-LD, and Microformats on the Web by analysing large Web crawls. His technical research focuses on large-scale data integration and includes topics such as information extraction, identity resolution, schema matching, data fusion, and data search. Christian Bizer holds an appointment as full professor at the University of Mannheim, where he leads the Web-based Systems Group.

The Sorbian languages.
After studying Slavic Studies and Historical Linguistics in Bonn, Eduard Werner has worked for ten years at the Sorbian institute in Bautzen/Budyšin and taught at the universities of Saarbrücken and Leipzig . He has been lecturer in Sorbian Studies in Leipzig since 2003 and is head of the research centre for minority languages. Eduard Werner is Germany-wide the only professor for the minority languages Upper and Lower Sorbian and educates not only linguists in Sorbian Studies but also future teachers in Upper and Lower Sorbian who are required as language teachers for the Sorbs in regions of East Germany.
