Contents

There is a lot of data available in the Web and in the Semantic Web. Web data is usually provided in a human-readable form of Web pages (including forms, the so-called Deep Web), while it cannot be processd in a database-style way by users. Data Extraction, e.g. from the CIA World Factbook or from Wikipedia, is thus a neverending "hot topic". Apart from pattern-based approaches, also Natural Language Processing Approaches are used.

The Semantic Web (cf. lecture Semantic Web) makes some attempts to provide, extend and/or annotate Web Data towards a machine-readable way. For this, the RDF data format is used, together with the OWL ontology language for describing metadata.

Form of the Seminar

The intention of the seminar is to get an overview of the state of the art in data integration from the Web and background data management.

For each topic, the following has to be done:

• a written tutorial-style paper that gives an overview of an approach,
• evaluate some tools, write a report (installation, functionality, usability, ...) [optionally german or english]
• prepare an illustrative medium-size case study using one or more tools (optionally: comparatively)
• a presentation giving the tutorial and showing a demo of how to use it (about 90 minutes incl. discussion; optionally german or english).
