GENERATION OF WORD FORMATIONS
</SectionTitle>
    <Paragraph position="0"> The unbalanced relation between the analytlc capabilities of natural language AI systems and their generatlve capabilities is found in the area of word formation as we\]\]. In HAM-ANS, research in word formation generation has started with two approaches. The first is a rather simple one: By analyzing compounds and derivatives, the system has created a semantic interpretation in terms of the language SURF and kept it in lexical memory. The basis for answer generation is a structure of the language SURF, which makes it possible to check agreement between certain parts of the answer and entries in \]exical memory. An example of this method is the substitution of the description LAMPE AUF DEM SCHREIBTISCH (lamp on the desk) by SCHREIB-TISCHLAMPE (desk \]amp).</Paragraph>
    <Paragraph position="1"> The second approach enables the system to make use of word formations in its own utterances without having previously analyzed a corresponding word. For those parts of utterances which might be verbalized using word formations, e.g. modified nouns or coordinate attributes, a set of patterns is provided which, by means of a matching process bind relation identifiers and canonical word forms. These are handed to a generation component whose task it is to decide on derivation, compounding or no word formation at all, and to yield morphologically correct junctures.</Paragraph>
