Tutorial given at ESWC 2005
Matching is one of the key operations for enabling the Semantic Web since it takes two schemas/ontologies, each consisting of a set of discrete entities (e.g., tables, XML elements, classes, properties, rules, predicates), as input and determines as output the relationships (e.g., equivalence, subsumption) holding between those entities. In this tutorial we introduce, via examples, the schema/ontology matching problem and its application domains. We provide a detailed discussion of the techniques used for schema/ontology matching with the help of a classification of matching approaches. We overview state of the art systems in light of the classification presented, indicating which part of the solution space they cover. Finally, we outline future research directions and new scientific challenges arising in schema/ontology matching.

Managing semantic heterogeneity is a critical task for the Semantic Web. Matching is one possible and promising solution, which have attracted a particular attention of academia and industry especially in the recent years.
The goal of the tutorial is to present the latest results in research and applications of schema-based schema/ontology matching by providing a detailed comprehensive coverage of state of the art matching techniques and matching systems in a systematic way from theoretical and application perspectives.

The slides of the tutorial can be found in the REASE repository: http://ubp.l3s.uni-hannover.de/ubp/PUSH/srchDetailsLR?lrID=lr-univ-pavel-1121707366586.
The audience is assumed to consist of both academia and industry. Thus, the tutorial can improve academic awareness of state of the art matching techniques and systems. Simultaneously, the tutorial will serve to inform industry representatives about existing research efforts that may meet their business needs. Moreover, it is central to the aims of the tutorial to show how technologies for matching of schemas and ontologies are going to evolve, indicating which research topics are in the academic agenda and which of them represent the scientific challenges that arise from the Semantic Web. We only expect from attendees a basic knowledge about data/conceptual modeling and graph theory. Knowledge about logics is advantageous.
