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.
