In the past decade, there has been an increasing need for semantic-aware data search and
indexing in textual (structured and NoSQL) databases, as full-text search systems became …

The Web has known a very fast evolution: going from the Web 1.0, known as Web of
Documents where users are merely consumers of static information, to the more dynamic …

In this paper, we present a new approach to merge OWL ontologies by semantic enrichment
of initial ontologies. This work is situated in the general context of stored information …

Ontologies are central artifacts in modern information systems. Ontology networks consider
the coexistence of different ontology models in the same conceptual space. It is relevant that …

Soft ontologies enable knowledge representation in a flexible way because they are more
susceptible to changes in their interrelationships over time. The transformation of a …

Soft ontologies aim to provide more flexible knowledge representations as compared with
hierarchy-based ontology models. Soft ontologies can restructure itself according to the …

In this paper we present a new mapping system for merging OWL ontologies. This work is
situated in the general context of stored information heterogeneity in a decisional system …

In this paper we present a new mapping approach of owl ontologies, using the reuse
technics. We propose also a refinement technic of mapping, to make it more pertinent. Our …

In this paper, we propose a reconciliation and cohabitation model of heterogeneous
information in Decisional Information Systems (DIS). Among this heterogeneous information …

Dans ce chapitre, nous rappelons les grandes étapes de l'évolution du Web, citons la
définition du terme Web sémantique et Ontologie, présentons le langage OWL, rappelons …
