TAILIEUCHUNG - Báo cáo khoa học: "A TOOL FOR THE AUTOMATIC CREATION, EXTENSION OF LEXICAL KNOWLEDGE"

A tool is described which helps in the creation, extension and updating of lexical knowledge bases (LKBs). Two levels of representation are distinguished: a static storage level and a dynamic knowledge level. The latter is an object-oriented environment containing linguistic and lexicographic knowledge. At the knowledge level, constructors and filters can be defined. Constructors are objects which extend the LKB both horizontally (new information) and vertically (new entries) using the linguistic knowledge. Filters are objects which derive new LKBs from existing ones thereby optionally changing the storage structure. . | A TOOL FOR THE AUTOMATIC CREATION EXTENSION AND UPDATING OF LEXICAL KNOWLEDGE BASES Walter .

Two levels of representation are distinguished a static storage level and a dynamic knowledge level. The latter is an object-oriented environment containing linguistic and lexicographic knowledge. At the knowledge level constructors and filters can be defined. Constructors are objects which extend the LKB both horizontally new information and vertically new entries using the linguistic knowledge. Filters are objects which derive new LKBs from existing ones thereby optionally changing the storage structure. The latter use lexicographic knowledge. INTRODUCTION Despite efforts in the development of tools for the collection sorting and editing of lexical information see Kipfer 1985 for an overview the compilation of lexical knowledge bases LKBs lexical databases machine readable dictionaries is still an expensive and time-intensive drudgery. In the worst case a LKB has to be built up from scratch and even if one is available it often does not come up to the requirements of a particular application. In this paper we propose an architecture for a tool which helps both in the construction extension and updating of LKBs and in creating new LKBs on the basis of existing ones. Our work falls in with recent insights about the organisation of LKBs. The main idea is to distinguish two representation levels a static storage level and a dynamic knowledge level. At the storage level lexical entries are represented simply as records with fields for spelling phonetic transcription lexical representation syntactic category case frames frequency counts definitions etc. stored in text files for easy portability. The knowledge level is an object-oriented .
