Lexical-Semantic and Ontological Resources Workshop Description Lexical-semantic and ontological resources are of fundamental importance for many applications within the areas of Natural Language Processing (NLP), Information Retrieval, and the Semantic Web. Semantic lexicons and wordnets usually have large coverage with respect to general vocabulary and are therefore well-suited to NLP-tasks such as semantic labeling and lexical chaining. Ontologies, on the other hand, often lack significant coverage or are restricted to special domains; moreover, they are typically more formalized and thus suitable for inference techniques. Various initiatives have been launched to convert semantic resources of the WordNet and FrameNet family to W3C standard representation languages such as RDF/OWL in order to make them more easily accessible to the Semantic Web community. Other approaches like the OntoWordNet project aim at the more demanding goal to fully axiomatize the semantic content of lexical-semantic resources. The workshop is intended as a forum to discuss possible interactions between lexical-semantic and ontological resources as well as their design, construction, extension, maintenance, validation, and application. Topics Contributions addressing the following topics are particularly welcome: * Interfaces (alignments, mappings) between lexical-semantic and ontological resources. Ontological enrichment of semantic resources, such as linking wordnets with existing upper or mid-level ontologies like SUMO, MILO, DOLCE, etc. * Meta-data approaches and standardization efforts for integrating different semantic and ontological resources. * Domain-specific extensions of lexical-semantic resources. * Automatic acquisition and extension of lexical-semantic and ontological resources by corpus-based methods or by exploiting other machine-readable knowledge sources. * Issues of multi- and interlinguality of lexical-semantic and ontological resources. * Tools and techniques for maintaining lexical-semantic resources and ontologies (e.g. graphical user interfaces, visualization tools, database techniques). * Applications of semantic lexicons and ontologies in all sorts of NLP-based information systems, especially with respect to evaluating the impact of these resources.
