Abstract
Out of context, a link like professors gives no certainty of where to place gods in relation to the parts of the speech. The link may be valid for example or some professors (e.g. in \textit{of the teachers intervened}) or express membership (e.g. The professors' books). In the first case it is the party article of a nominal link, in the second it is the preposition that introduces a complement of specification. This case of homonymousness can be traced back to the area of \textit{Word Sense Disambiguation}, but its relevance to syntax and NLP is evident. Nevertheless, in the literature of it we found no trace. The work distinguishes different functions of the members of the series and proposes an algorithm to disambiguate the two related uses and others, for example the right complements (as in \textit{Take advantage of your brothers}) that make disambiguation even more complex.

Introduction
This work focuses on the party article in Italian, etymologically formed by a definite article and by a definite article. The whole series, of the, of the, of the, of the, of the, of the, of the, is on the surface identical to the homonymous articulated prepositions. Even at first glance, the variety of outcomes obtained by placing a sequence like professors in different contexts, with some here taken as a representative element of the seven members of the series, is amazement at the number of uses and the consequent difficulties that this creates in the NLP. The objective of our work is automatic disambiguation. The difficulties that such a task poses are numerous. The study is part of a broader research that aims at the automatic identification of the Subject and the references contained therein.} of a simple phrase AUTHOR. In general, the partitivo article is not a frequent element in the texts, but its relevance in order to obtain greater precision in the search of the Subject is evident, as will be seen in the following. The sec section:ambiguita is dedicated to the semantic ambiguities that the homonymous generates, deriving from structural ambiguities. The section sec:disambiguation presents some of the grammatical ambits that create obstacles for the correct identification of the party articles. Each of these ambits has determined a part of the script presented, which has been tested on a corpus formed by 463 occurrences (randomly chosen from the total 580) of the elements of the paradigm found in the novel Palomar by Italo Calvino. The conclusion section concludes the work by presenting the results obtained.

Conclusion
The process of automatic disambiguation of sequences introduced by of + partitive article presented here gave rise to promising results, in particular for the identification of the specification complements. In order to be able to speak of information retrieveval, however, a statistical sample of some relevance is necessary; the small number of sentences falling in the remaining cases referred to in section sec:disambiguation would make its indicators useless, so it was chosen not to propose them. It is necessary to work again on the corpus both to treat the remaining occurrences already identified and to enrich it with new sentences. Moreover, as the algorithm works for elimination, it might be useful to propose a different order of assessment of cases, in view of better results.
