  This paper explores the acquisition of conceptual knowledge from bilingual
dictionaries (French/English, Spanish/English and English/Spanish) using a
pre-existing broad coverage Lexical Knowledge Base (LKB) WordNet. Bilingual
nominal entries are disambiguated agains WordNet, therefore linking the
bilingual dictionaries to WordNet yielding a multilingual LKB (MLKB). The
resulting MLKB has the same structure as WordNet, but some nodes are attached
additionally to disambiguated vocabulary of other languages.
  Two different, complementary approaches are explored. In one of the
approaches each entry of the dictionary is taken in turn, exploiting the
information in the entry itself. The inferential capability for disambiguating
the translation is given by Semantic Density over WordNet. In the other
approach, the bilingual dictionary was merged with WordNet, exploiting mainly
synonymy relations. Each of the approaches was used in a different dictionary.
  Both approaches attain high levels of precision on their own, showing that
disambiguating bilingual nominal entries, and therefore linking bilingual
dictionaries to WordNet is a feasible task.
