Cíle předmětu
The objective of the course is to explain the problems of information retrieval in large collections of unstructured data, such as text documents or multimedia objects. The main emphasis will be on describing the basic principles of distributed algorithms for processing large volumes of data, e.g., Locality Sensitive Hashing, MapReduce, or PageRank. The algorithms for processing stream data will be introduced as well. The students will also acquire practical experience by applying the presented algorithms to specific tasks.
Výstupy z učení
After completing the course, students are able to:
  • Describe algorithmic-based differences between processing offline data collections and online data streams;
  • Understand the basic principles of distributed algorithms for processing large volumes of data;
  • Evaluate the results of algorithms by several metrics;
  • Apply presented algorithms, such as k-Means, Locality Sensitive Hashing, MapReduce, or PageRank, to specific tasks.
    • Osnova
    • Introduction – what is searching, things useful to know
    • Support for distributed processing – distributed processing, MapReduce, performance evaluation
    • Retrieval operators and metrics – common similarity search operators, retrieval metrics for evaluating search results
    • Clustering – clustering in Euclidean and non-Euclidean spaces; hierarchical, k-means, and BFR clustering algorithms
    • Finding frequent item sets – counting frequent items; A-Priori and PCY algorithms
    • Finding similar items – near-neighbor search, shingling of documents, min-hashing, Locality Sensitive Hashing
    • Processing data streams – sampling data from a stream, queries over sliding windows, filtering a stream
    • Link analysis – PageRank, topic sensitive PageRank, link spam
    • Search applications – advertising on the web, recommender systems
