Different Issues in the Design of a Lemmatizer/Tagger for Basque

This paper presents relevant issues that have been considered in the design of a general purpose lemmatizer/tagger for Basque (EUSLEM). The lemmatizer/tagger is conceived as a basic tool necessary for other linguistic applications. It uses the lexical data base and the morphological analyzer previously developed and implemented. Due to the characteristics of the language, the tagset here proposed in structured in for levels, so that each level is a refinement of the previous one in the sense that it adds more detailed information. We will focus on the problems found in designing this tagset and on the strategies for morphological disambiguation that will be used.

Lexical Knowledge Representation in an Intelligent Dictionary Help System

The frame-based knowledge representation model adopted in IDHS (Intelligent Dictionary Help System) is described in this paper. It is used to represent the lexical knowledge acquired automatically from a conventional dictionary. Moreover, the enrichment processes that have been performed on the Dictionary Knowledge Base and the dynamic exploitation of this knowledge - both based on the exploitation of the properties of lexical semantic relations - are also described.
