Logos 8, the next generation of the Logos Machine Translation (MT) system, is a client server application, which realizes the latest advances in system design and architecture. A multi-user, networkable application, Logos 8 allows Internet or Intranet use of its applications with client interfaces that communicate with dictionaries and translation servers through a common gateway. The new Logos 8 technology is based on a relational database for storage and organization of the lexical data. In this paper, we present Term-Builder, the Lexical Knowledge Acquisition tool developed for Logos 8. The new automatic coding functionality within Term-Builder is significantly improving the process of acquiring new lexicons for MT and other applications.
