8th International Workshop on |
The 8th International KRDB Workshop continues the tradition of annual
international workshops devoted to facilitate cross-fertilization between
the fields of knowledge representation (KR) and databases (DB), started in
1994. KRDB-2001 will be held at the Pontificia
Università Urbaniana in Roma (Italy), on September 15, 2001, as a
workshop of the 27th International Conference on Very Large Data Bases. The
deadline for submission is May 20, 2001.
Topics
KRDB-2001 will focus on Modeling, Querying and Managing Semistructured
Data. Semistructured data are data that are self-describing, irregular,
and with a structure that is partially known, or subject to frequent
changes. They are usually formalized in terms of labeled graphs, and capture
data as found in many application areas, such as web information systems,
digital libraries, and data integration. Database researchers are studying
several aspects of semistructured data, including how to model such data, how
to query and restructure them, and how to store and manage them. On the other
hand, there are many kinds of reasoning that can be carried out on
semistructured data in order to support the above tasks. For instance, the
discovery of certain regularity may help in deciding the appropriate storage
structures in a particular context, or, the fact that a certain schema
subsumes another one may help in comparing data coming from different
sources, or in translating data from a certain format to another one. The
goal of the workshop is to bring together people from the Database and the
Knowledge Representation and Reasoning communities, in order to compare
different points of views and various sets of techniques that can be used for
the tasks related to Modeling, Querying and Managing Semistructured Data.

TITLE: Declarative Information Extraction, Web Crawling and Recursive Wrapping with Lixto SPEAKER: Georg Gottlob, Vienna University of Technology, (TU Wien) ABSTRACT: Lixto is a system and method for the visual and interactive generation of wrappers for Web pages under the supervision of a human developer, for automatically extracting information from Web pages using such wrappers, and for translating the extracted content into XML. In this talk, we describe some advanced features of Lixto, such as disjunctive pattern definitions, specialization rules, and Lixto's capability of collecting and aggregating information from several linked Web pages. We illustrate these features with significant examples from the commercial domain. Joint work with Robert Baumgartner and Sergio Flesca. |
