Two problematic issues in most lexi- con systems today are their size and re- stricted domain of use. In this paper, we introduce a new approach to lexical or- ganization that leads to more compact and flexible lexicons. The lexical en- tries are conceptual/phonological frames rather than word entries, and a num- ber of expansion rules are used to gen- erate entries of actual words from these frames. A single frame supports not only all forms of a word, but also words of dif- ferent categories that are derived from the same semantic basis. The whole theory is now being implemented in the TROLL lexicon project.
