4 Conclusions
</SectionTitle>
    <Paragraph position="0"> The Sign Model (SM) gives a theoretical foundation for structuring lexical information along semantic lines* It prescribes a strong semantic basis and suggests various kinds of expansion rules for generating complete word entries. The sign expansion approach is now used as a basis for the TROLL lexicon project in Trondheim. In this project, a formalism for lexical representation as well as mechanisms for executmg lexical rules are implemented in LPA Prolog (Gulla and Moshagen, 1995). A lexicon of Norwegian verbs is under construction, and SM-based analyses of En- null glish, German, and Bulgarian have been used in the design of the lexicon (Hellan and Dimitrova-Vulchanova, 1996; Pitz, 1994). Due to speed concerns, the stored entries and the expansion rules are in the TROLL lexicon supplemented with indexes that refer to well-defined derivational sequences for complete word entries. The work in the TROLL project is now concentrated on the construction of a complete lexicon for Norwegian, and this work is also to serve as an evaluation of both the lexicon structures and the Sign Model.</Paragraph>
    <Paragraph position="1"> The theory is still at a development stage when it comes to psychological and perceptional matters, even though some suggestions have been made (Gulla, 1994). The filture work also includes establishing proper interfaces to various syntactic theories, so that the system can be integrated with existing parsers and generators.</Paragraph>
