title: xLiD-Lexica: Cross-lingual Linked Data Lexica

description: We provide <strong>cross-lingual linked data lexica called xLiD-Lexica</strong>. The data set contains the <strong>cross-lingual groundings of linked data resources from the Linked Open Data cloud as RDF data</strong>, which can be easily integrated into the LOD data sources. In addition, we created a SPARQL endpoint over ourxLiD-Lexica to allow users to easily access them using SPARQL query language. Multilingual and cross-lingual information access can be facilitated by the availability of such lexica, e.g., allowing for an easy mapping of natural language expressions in different languages to linked data resources from LOD. Many tasks in natural language processing, such as natural language generation, cross-lingual entity linking, text annotation and question answering, can benefit from our xLiD-Lexica. More information can be found in the <strong>LREC'14 paper <em>xLiD-Lexica: Cross-lingual Linked Data Lexica</em></strong> and on our website <strong>https://km.aifb.kit.edu/sites/xlid-lexica/</strong>.
