A Holistic Paradigm for Large Scale Schema Matching
… essentially relied on finding pairwise attribute correspondences in isolation. In contrast, this thesis proposes a new matching paradigm, holistic schema matching, to match many schemas at the same time and find all matchings at once. By handling a set of schemas together, we can explore their …

This can be done, in some cases, by aligning or matching heterogeneous ontologies. Thus, establishing the relationships between terms in the different ontologies …

Information Quality Criteria Analysis in Query Reformulation in Dynamic Distributed Environments
… specific domain and are linked to each other by correspondences (semantic connections). Nonetheless, a challenge inherent to dynamic distributed environments is the query reformulation process between a pair of peers. When a user poses a query at a peer, in order to acquire more information, the …
