A semantic approach for constructing valid composition scenarios of linguistic Web services.

Constructing Linguistic Web Services (LingWS for short) is a difficult task that requires expertise in both linguistic and software engineering. The challenge is to manage the various and richness linguistic knowledge and the heterogeneous Natural Language Processing (NLP for short) using the web service technology. In this paper, we propose a semantic approach to improve the composition of LingWS. First, we provide a rich NLP domain ontology that covers the data and processing concepts in a fine granularity and richness relationships between these concepts. Second, we proceed with the generation of an ontological view from the rich proposed NLP domain ontology using a set of selection criteria. A view delimits the linguistic ontology to the user’s needs. Starting from this view, the user will be assisted in selecting a valid processing scenario, assimilated to a scenario of linguistic services, with respect to the coherence, completeness and redundancy properties. In order to prove the feasibility of the proposed approach, we carried out an experiment on the morphological level.
