CONCLUSIONS
</SectionTitle>
    <Paragraph position="0"> The paper presents a parsing strategy able to cope with different kinds of syntactic ill-formed hess: ellipsis, conjunctions, syntactic errors. Some examples are reported to show that the adopted for malism allows the parser to analyse ill-formed fra~ ments without substantial changes to the rules used to analyse correct sentences.</Paragraph>
    <Paragraph position="1"> However, some problems still deserve further attention. First of all, in case of ill-formed sen tences it is often possible to assign more than one interpretation to the sentence (e.g. in &amp;quot;The boy love the girl&amp;quot; the subject can be considered plural - missing &amp;quot;s&amp;quot; in &amp;quot;boy&amp;quot; - or singular - missing &amp;quot;s&amp;quot; in &amp;quot;love&amp;quot;); this can also happen for correct sen tences (see the last example in the section on CONJUNCTIONS). The current version of the system should be enhanced both by taking into account con textual information (which could be useful in the first case) and by weighing in some way the output of the semantic component (which, today, is catego~ ical: yes or no).</Paragraph>
    <Paragraph position="2"> As regards the context, the experiments we made on the parser refer to isolated sentences, so that the &amp;quot;pattern matching&amp;quot; procedure we referred to in the section on ELLIPSIS (see the example &amp;quot;John&amp;quot;) is neither implemented nor designed. Our belief is that the two components (pattern marcher and parser) are quite independent each other, but we are planning to address also issues connected with discourse analysis.</Paragraph>
    <Paragraph position="3"> Last but not least, some problems are more strictly connected with the basic parser design.</Paragraph>
    <Paragraph position="4"> Some English sentences break a locality principle embodied in the first-level syntactic rules. An example is given by &amp;quot;What architect do you know who likes the balalaika&amp;quot; (see Winograd 83, pag.136). We are currently studying this problem, whose solution will involve a change in the final representation as well as in the rule packets.</Paragraph>
    <Paragraph position="5"> The current version of the parser, that runs on a VAX-II/780 under the UNIX operating system and is implemented in FRANZ LISP, includes the mecha nisms for detecting and recovering the lexical, agreement, and word ordering errors, whereas the &amp;quot;extra cases&amp;quot;, in the sense explained above, are currently being implemented.</Paragraph>
