The Lexical Data Base (LDB) and the Lexical Knowledge Base (LKB) have played, as software systems, a core role within Acquilex I Esprit 3030 project. Main limitations were derived from the fact that the LDB and the LKB are two different systems, designed to fulfill different functional specifications, in order to perform different operations. LDB software provides, basically, database-like access to lexical information. LKB software manages a lexical Knowledge Representation based on typed feature structures (FSs) allowing operations on lexical entries such as inheritance, unification, generalisation, lexical rules, etc. The central aim of the LDB/LKB integration software is to provide new tool for loading intermediate and relative stable versions of lexicons developed in the LKB into the LDB, allowing, in this way, flexible access/search to entries based on any aspect of their contents.
