Focused crawling in the ALVIS semantic search engine

Publiceringsår: 2005
Språk: Engelska
Sidor: 19-20
Dokumenttyp: Konferensbidrag


The EU project ALVIS - Superpeer Semantic Search Engine,
aiming at developing an Open Source prototype of a
peer-to-peer, semantic based search engine, is brie°y presented.
A focused (or topic speci¯c) crawler, responsible for
creating topic-speci¯c databases within ALVIS, is presented
in more detail. It is based on a combination of a standard
Web crawler and an automated subject classi¯er. The topic
focus is provided by an ontology that is used as topic de¯nition.
When a document have been deemed relevant further
processing (like character set normalization, language identi
¯cation and simple text segmentation), is done in preparation
for the ALVIS processing pipeline.
