AbstractResults are presented of an ongoing project of the Dutch TST-centre for language and speech technology aiming at linking of various lexical databases. The project involves four Dutch monolingual lexicons: WlNT05, e-Lex, RBN and RBBN. These databases differ in organisational structure and content. To enable linkage between these lexicons, we developed a common feature value set and a common organisational structure. Both are based upon existing standards for the creation and reusability of lexicons: the Lexical Markup Framework and the EAGLES standard. Examples of the content and structure of each of the lexical databases are presented in their original form. Also, the structure and content is shown when mapped onto the common framework and feature value set. Thus, the commonalities and the complementarity of the lexical databases are more readily apparent. Besides, this elaboration of the databases opens up the opportunity for mutual enrichment.
