This is a one-hour video recording of the presentation of Ilya Zaihrayeu at the First Asian Autumn School on the Semantic Web. It comprises the video synchronized with the slides (requires Flash) or the video alone. Table of Contents: Ontology Matching and Alignment Matching operation Example: two XML schemas Example: two ontologies Statement of the problem Applications Applications: Information integration Applications: summary Classification of basic techniques Classification of techniques (simplified) Basic techniques Systems: analytical comparison Semantic matching in a nutshell Concept of a label & concept at a node Four macro steps Step 1: compute concepts at labels Step 2: compute concepts at nodes Step 3: compute relations between (atomic) concepts at labels Step 3: Element level semantic matchers Step 4: compute relations between concepts at nodes Step 4: Example of a node matching task Motivation: Problem of low recall (incompletness) On increasing the recall: an overview Iterative semantic matching (ISM) ISM: Discovering critical points - example ISM: Generating candidate axioms ISM: generating candidate axioms Hierarchy Distance Test cases Matching systems Experimental results, test case #4 Experimental results, test case #5 Experimental results, #6,7,8: incompleteness Experimental results, #6,7,8: incompleteness (OAEI-2006 comparison) Outline Summary Future challenges (Some) references You are welcome to attend (11 Nov): 'Thank you'
