Discusses various theoretical approaches to the semantic analysis of lexical units, focusing on the componential or axiological approach which defines a unit's semantic "value" as the combination of certain distinctive features. Concludes that this approach, so far, has not offered much practical assistance to translators faced with…

Lexical semantics and contrastive lexical semantics can serve as a background discipline to describe and, to some extent, to explain errors in interlanguage. Two developments in lexical semantics that are relevant in this area are the description of sense-relationships and componential analysis. Contrastive lexical semantics involves mapping the…

Presents an algorithm for use in natural language document retrieval systems which automatically determines if the conjunction "and" in a statement representing an information need should be translated into a Boolean "and" or "or." The results of an experiment that used the algorithm are reported, and further research is suggested. (CLB)

Describes a system developed for the automatic recognition of biological concepts in titles of scientific articles; reports results of several pilot experiments which tested the system's performance; analyzes typical ambiguity problems encountered by the system; describes a disambiguation technique that was developed; and discusses future plans…
