OSIRIS

Abstract

OSIRIS (Ontology-based Systems for Semantic Information Retrieval and Indexation dedicated to community and open web Spaces) is a platform dedicated to the development of community web spaces which aim at facilitating both semantic annotating process and searching process of multimedia resources. Based on the use of both heavyweight ontologies and thesauri, OSIRIS allows the end-user (1) to describe the semantic content of its resources by using an intuitive natural-language based model of annotation which is founded on the triple (Subject, Verb, Object), and (2) to formally represent these annotations by using Conceptual Graphs. Each resource can be described by adopting multiple points of view, which are usually provided by different end-users. These different points of view can be defined by using multiple ontologies which can be related to connected (or not-connected) domains. Developed from the integration of Semantic Web technologies and Web 2.0 technologies, OSIRIS aims at facilitating the deployment of semantic, collaborative, community and open web spaces. The use of OSIRIS is illustrated in the context of a project dedicated to the preservation of French popular and cultural heritage.
