:: Welcome to the WebAlgo Group

WebAlgo is a group of Computational Mathematics - Institute of Informatics and Telematics (IIT), at the National Research Council (CNR) in Pisa, in collaboration with the Department of Informatics of the University of Piemonte Orientale , and the Department of computer science of the University of Pisa. The research of this group is oriented to solving the challenging problems arising from the applications of Information Retrieval and Data Mining objectives and concepts to the World Wide web scenario.
In particular we have been working on:
  1. Clustering and labeling of web snippets in meta search engines.
  2. Detection and extraction of implicit cyber-communities in the web graph.
  3. Models for structural properties of the web graph
  4. Automatic generation of summaries for Digital Videos
  5. Data Compression
  6. Models and algorithms for On-line Ad-Words auctions

Tools developed:
  • Armil: a Clustering Meta-search Engine that allows users to send queries simultaneously to Google and Yahoo. The snippets returned by Google and Yahoo are grouped by Armil into homogeneous groups by topic.
  • Community Watch: a tool for visualizing dense subgraphs of several snapshots of the web graph: the whole web in 2001, the national domain.it of year 2004 and the national domain .uk of year 2005.
  • ViSto:a tool for making on-the-fly personalized static summaries of short videos.
  • A Lightweight Suffix Array and BWT Construction Algorithm (Available here)
  • The Data Compression Boosting Library (Available here)
