FINAL REMARKS
</SectionTitle>
    <Paragraph position="0"> Due to the lack of space, we will discuss here neither the processing units of our environment nor the control flows between them. The interested reader may find all the necessary details in Tufts and Popescu (1990a) and Tufts and Popescu (1990b).</Paragraph>
    <Paragraph position="1"> Yet, we have to say that the proper morpho-lexical processings (analysis and generation), were thought to work in a concurrent manner. For instance reading characters from the keyboard, parsing individual word-forms, spelling checking and parsing syntagms are usually simultaneously active proceases; similarly, individual word-forms generation and syntagms expansion are typical coroutines.</Paragraph>
    <Paragraph position="2"> It is worth mentioning that, by default, the result of parsing as provided by our system is not a linear sequence of unique lexical items. The result includes all valid interpretations of every word in the input (including unknown words) thus generating lexically ambiguous dements, as well as all legal groupings of syntagmatic components thus genera- 99 ting iexically ambiguous structures.</Paragraph>
    <Paragraph position="3"> If such a complete analysis is not desirable, a set of general-purpose heuristics may be used to filter the parsing (for instance when a word may be segmented in different ways, taking into account only the roots corresponding to the longest endings, considering the syntagms with the maximum number of constituents, etc., see Tufts (1990)).</Paragraph>
    <Paragraph position="4"> With respect to spelling errors recovery, we distinguish between typing and linguistic anomalies.</Paragraph>
    <Paragraph position="5"> The typing errors are the usual misspellings taken into account by the spelling checkers of text editors. Anyway, there is an important difference: because (normally) our dictionaries are root-oriented, the standard spelling checking refers to the roots. With the endings, due to the limited number and limited length and thanks to the discriminating organization of the endings tree, the recovery is much more precise (the recovery is always complete when the root was found in the dictionary).</Paragraph>
    <Paragraph position="6"> The case when the morphological features of the root of a word-form are not completely congruent with the morphological features of its recognized ending is considered a linguistic error. The congruency checking allows for an easy recovery of such mistakes. The distinct treatment of this type of error is very useful in case of CAI systems for language learning (Zock et al. 1990) and we intend, in the near future, to provide an explanation module to the congruency checker for such applications.</Paragraph>
    <Paragraph position="7"> The generation process is bound to the morphological level, i.e. the lexical items are produced by a higher level module in the order they are supposed to appear in the output natural language string.</Paragraph>
    <Paragraph position="8"> An exception from this rule is given by syntagmatic symbols generation. As previously shown, the pattern of a syntagm may specify one or more &amp;quot;alien&amp;quot; constituents (such as adverbs or pronouns). While expanding such a pattern, a '&lt;' or '&gt;' marked constituent is imported into the syntagmatic sequence from the left or from the right of the syntagmatic symbol, thus changing the initial ordering. null TheMORPHIS system, described in this paper is partially implemented in GOLDEN COMMON-LISP for IBM PC-AT compatible personal computers. null At present, a user-friendly interface is under development, whicll is supposed to decrease as much as possible the level of expertise required to a user in order to build his/her own morphological knowledge base.</Paragraph>
    <Paragraph position="9"> The interface will also include on-line consulting facilities and the system will be equipped with configuration possibilities and standard linking interfaces for three main types of applications: advanced text-editing, language-learning and machine translation (including NL interfaces).</Paragraph>
