Course Aim & Organization

The course covers tools and systems adopted to handle big data, e.g., large collections of textual data. In the first part, the course focuses on the analysis of information embedded in large collections, using tools that range from decision trees, classification rules, association rules, graph-based link analysis. The second part of the course covers the efficient retrieval of information, discussing the algorithms and data structures adopted to enable answering keyword based queries, as well as indexing methods to enable fast search.

Teachers

The course is composed by a blending of lectures and exercises by the course teacher and a teaching assistant.

Course Program

The course outline is:

  • Data mining
    • The Data Mining process
    • Decision Trees and Decision Rules
    • Rule Induction Methods
    • Association Rules
    • Frequent Itemset Analysis
  • Web information retrieval
    • Web modelling and crawling
    • Graph-based retrieval models (PageRank, HITS)
  • Text-based information retrieval
  • IR models (Boolean models, vector space models, probabilistic models)
    • Evaluation of IR systems
    • Text processing
    • Advanced IR models (Latent Semantic Indexing)
  • Indexing
    • Inverted indexing
    • Multidimensional indexing
    • Rank aggregation
