The proposed paper reports on work in progress aimed at the development of a conceptual lexicon of Modern Greek (MG) and the encoding of MWEs in it. Morphosyntactic and semantic properties of these expressions were specified formally and encoded in the lexicon. The resulting resource will be applicable for a number of NLP applications.

Computational approaches to sentiment analysis focus on the identification, extraction, summarization and visualization of emotion and opinion expressed in texts. These tasks require large-scale language resources (LRs) developed either manually or semi-automatically. Building them from scratch, however, is a laborious and costly task, and re-using and repurposing already existing ones is a solution to this bottleneck. We hereby present work aimed at the extension and enrichment of existing general-purpose LRs, namely a set of computational lexica, and their integration in a new emotion lexicon that would be applicable for a number of Natural Language Processing applications beyond mere syntactic parsing.

L'étude que nous présentons ici fait partie de l'élaboration d'une grammaire des sentiments en grec moderne, dans le cadre du Lexique-Grammaire. C'est une étude de la combinatoire des noms de sentiments (environ 85 items) avec des verbes spécifiques exprimant des modalités diverses (aspect, intensité, contrôle, manifestation ou expression verbale). Après avoir défini trois classes des noms de sentiments à partir de leurs propriétés syntaxico-sémantiques, nous nous proposons de vérifier notre classification générale en termes de combinatoire lexicale. L'examen détaillé des phrases recensées met en évidence les restrictions que les noms imposent sur le choix lexical des verbes. Il s'avère que, dans la majorité des cas, ces restrictions sont corrélées avec les propriétés définitionnelles de nos classes syntaxiques. Ces relations combinatoires entre verbes et noms nous amèneront à reconsidérer la question du figement de ces expressions.

In this article we have stressed the treatment of the genitive case for a syntactic classification of sentences containing frozen complements: the genitive presents a problem to the extent that several syntactic functions can be assigned to it. Thus, on the one hand we examine sentences whose complement in the genitive is frozen and, on the other hand, we examine frozen sentences whose genitive complement is free. In the first case, we use three tests to determine the syntactic status of the genitive in question: (i) the alternation of the genitive complement with a prepositional phrase; (ii) a comparison with free sentences having an equivalent structure; (iii) the paraphrase of the genitive complement by an adverbial, which is frequently prepositional. In the second case, when the base form is N0 V C (accus) N (gén), we have made use of such properties as the following: (i) the pronominalisation in the form of a Ppv, (ii) the pronominalisation in the form of a Poss, (iii) the alternation of the genitive with a prepositional phrase (à N (accus)), which brings out distinct structures quite clearly. In this way, taking syntactic criteria into account for the analysis of (free or frozen) genitive forms allows us to set up classes that are more homogeneous from the point of view of their syntax. We have also been able to observe that cases, as morphological markers, play no essential role in the criteria that constitute the basis of our classification.
