R\u00e9sum\u00e9 :<\/strong><\/p>\n

Les travaux de recherche men\u00e9s autour de la description de services Web utilisent de plus en<\/p>\n

plus des mod\u00e8les s\u00e9mantiques pour fournir une repr\u00e9sentation interpr\u00e9table automatiquement.<\/p>\n

Toutefois, nous avons d\u00e9cel\u00e9 des lacunes dans les approches s\u00e9mantiques actuelles qui engendrent<\/p>\n

ambigu\u00eft\u00e9 et non pertinence au niveau de l\u2019appariement et de la d\u00e9couverte de services<\/p>\n

Web.<\/p>\n

Pour rem\u00e9dier \u00e0 ces lacunes nous proposons des contributions \u00e0 la description et \u00e0 la d\u00e9couverte<\/p>\n

de services Web s\u00e9mantiques. En ce qui concerne la description de services, nous avons<\/p>\n

d\u00e9fini un langage bas\u00e9 sur une recommandation W3C. En plus d\u2019une annotation m\u00e9tier s\u00e9mantique<\/p>\n

des \u00e9l\u00e9ments d\u2019un service, notre principale contribution \u00e0 la description s\u00e9mantique consiste<\/p>\n

\u00e0 sp\u00e9cifier la nature de ces annotations en utilisant une ontologie technique que nous avons d\u00e9finie.<\/p>\n

Cette ontologie fusionne plusieurs concepts s\u00e9mantiques de services Web que nous avons<\/p>\n

identifi\u00e9s dans des approches existantes et int\u00e8grera d\u2019autres concepts qu\u2019on d\u00e9finira ult\u00e9rieurement<\/p>\n

sans pour autant modifier notre langage de description ou nos techniques d\u2019appariement<\/p>\n

associ\u00e9es.<\/p>\n

Nous avons \u00e9galement d\u00e9fini un algorithme d\u2019appariement entre une requ\u00eate de service et<\/p>\n

les descriptions des services publi\u00e9s. Cet algorithme se base sur un appariement entre \u00e9l\u00e9ments<\/p>\n

d\u2019une requ\u00eate et un service publi\u00e9 et trois techniques d\u2019agr\u00e9gation des r\u00e9sultats d\u2019appariements<\/p>\n

\u00e9l\u00e9mentaires. L\u2019algorithme tire avantage de la description s\u00e9mantique que nous avons d\u00e9finie. Il<\/p>\n

a \u00e9t\u00e9 mis en oeuvre dans un annuaire de services Web s\u00e9mantiques et a \u00e9t\u00e9 \u00e9galement compar\u00e9<\/p>\n

aux algorithmes de r\u00e9f\u00e9rence. Les exp\u00e9rimentations montrent clairement l\u2019efficacit\u00e9 de notre<\/p>\n

approche en termes de temps de r\u00e9ponse et de pr\u00e9cision.<\/p>\n

Abstract :<\/strong><\/p>\n

Researchs conducted aroundWeb service description use more and more of semantic models<\/p>\n

to provide an automatically interpretable representation. However, we identified gaps in current<\/p>\n

approaches that generate semantic ambiguity and impertinence at Web service matching and<\/p>\n

discovery.<\/p>\n

To address these shortcomings we propose contributions about semantic Web service description<\/p>\n

and discovery. As for the Web services description, we have defined a language based on<\/p>\n

a W3C Recommendation. In addition to a semantic business annotation of service components,<\/p>\n

our main contribution about the semantic description is to specify the nature of these annotations<\/p>\n

using a technical ontology that we have defined. This ontology merges several semantic concepts<\/p>\n

of web services that we identified in existing approaches and may include other concepts that can<\/p>\n

be defined later without changing our description language or our matching techniques.<\/p>\n

We also defined a matching algorithm between a service request and published service descriptions.<\/p>\n

This algorithm is based on matching between elements of a service request and descriptions<\/p>\n

of published services. This matching is may be computed by three aggregation techniques<\/p>\n

of the results of those elements\u2019 matching. The algorithm takes advantage of the semantic description<\/p>\n

we have defined. It was implemented in a semantic web services registry and was also<\/p>\n

compared to referenced algorithms. The experiments clearly demonstrate the effectiveness of our<\/p>\n

approach in terms of response time and precision.<\/p>\n
