    <Paragraph position="0"> In this document, we have shown some elements of a method to identify, in a generative perspective, the behavior of prepositions in mono- and multi-lingual contexts. We have initialized a discussion on the delimitation of senses, from observed uses, and have proposed a semantic representation for each of them based on the LCS.</Paragraph>
    <Paragraph position="1"> From the examples given in here, we can see that some regularities can be quite easily captured and dealt with by means of relatively simple tools, whereas a number of complex cases need much more attention and solutions seem to require a pragmatic interpretation, or long enumerations of specific realizations. Besides the obvious need of several steps of evaluation, we now have in mind to develop a form a lexical tuning to enrich the semantic characterization of preposition senses, at three levels: selectional restrictions or constraints identifying senses, preferences among senses (some are much more prominent or prototypical than others) and refining the LCS representation to accommodate different forms of e.g. metaphors and metonymies.</Paragraph>
