Indexing medical WWW documents by morphemes.
Assisting users to search medical information on the WWW is here considered from two perspectives--the linguistic complexity of medical terms, nominal compounds in particular, and cross-lingual relationships between monolingual medical terminologies. In order to solve the first problem, we present an approach to automatic indexing in which medically plausible morphological units are used. Semantic value is added to these index terms by a compact domain-specific thesaurus. We further discuss tools for morphological segmentation and morphosemantic normalization of HTML documents, as well as an adaptation of a standard WWW search engine for morpheme-based retrieval. The second problem, cross-lingual medical document retrieval, is dealt with by defining cross-lingual equivalence relations on the emerging morpheme sets.
