8 Efficiency
</SectionTitle>
    <Paragraph position="0"> This section reports on an experiment in which the efficiency of the proposed underspecified construction mechanism was measured against the cost of generating all UDRSs separately. Table 1 compares the time behaviour of constructing one underspccified structure (U-Time) with the time needed for constructing of the whole bunch of specified structures (S-Time). The experiment was conducted on a SPARCstation 20 using input sentences of the form I saw a man (with a telescope ff .</Paragraph>
    <Paragraph position="1"> Visibly the time needed per reading remains approximately constant in the construction of the underspecified representation whereas it grows sharply when the ambiguities are enumerated.</Paragraph>
