Introduction

Introduction

The Web is becoming a truly multilingual hub in whichspeakers from different languages and cultures are producing,

interacting and consuming information.

Web services are an essential part of the Web which nowadaysattract more and more people around the world.

So, supporting multilingual Web services discovery is a crucialgoal to achieve, so that providers and users publish or

consume Web services independently from their culture and

native language.

Why DBpedia for services discovery

and Multilingual support

DBpedia Multilingual aspect

DBpedia :

Multi-domain, extendable KB

Its resources are described with ontologies such as Yago,UMBEL, WordNet...

DBpedia categories are organized and semantically related bySKOS vocabulary.

They are multilingual, every language have a separateddataset (DBpedia Chapter).

DBpedia chapters are interlinked to each other. Every DBpedia resource have possible redirects for synonyms,

acronyms and misspelling.

Resources disambiguations of homonyms help users to selectnon-ambiguous search terms to search services

Implementation and Analysis

services annotation

We have used 144 DBpedia resources to annotate a collectionof 170 services

123 are from OWL-S TC 4, and 47 are accumulated from thepublic repositories

DBpedia provides roughly all necessary resource forannotation.

However, some concepts (such as PAREDFOOD) are missing. While other annotation have been improved.

Multilingual support analysis

Implemented prototype supports 5 languages : English,Deutsch, Italian, Spanish and French.

Weve used Jena and its RDF store to query and store datafrom different DBpedia chapters endpoints

Conclusion and future works


We used DBpedia to support multilingual web servicesdiscovery

We intend to explore more LOD data to improve web servicesannotations and multilingual discovery

The approach will be a part of semantic services discoveryframework based on LOD.
