Related projects applying NLP tools E.g., The PATHS project has developed techniques to enrich English and Spanish collections 1)Identification of key entities 2)Detection of (typed) similarities between objects, using metadata 3)“Background links” to external resources such as Wikipedia 4)Classification of object against a hierarchy of topic Applying these techniques to other languages would require work 1)requires language-specific tools (PoS tagging, lemmatization) 2)is straightforward to apply to new languages 3)requires language-specific tools 4)depends on (3) and on translation of some topics
  10. 10. Language challenges for Digital Libraries  Typical queries are very short Average < 2 terms  Identification of query language is not easy, even manually 39% of queries may belong to several languages  Plenty of named entities 60% of queries are for persons & places Not only is it hard for queries: the same issues apply to the descriptive metadata Studies by Humboldt University on Europeana and The European Library
