Course objectives
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 given on describing 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 the specific tasks.
Learning outcomes
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 the specific tasks.
  • Introduction – What is searching, Things useful to know
  • Support for Distributed Processing – Distributed file system, MapReduce, Algorithms using MapReduce, Cost model and performance evaluation
  • Retrieval Operators and Result Evaluations – Common similarity search operators, Retrieval metrics
  • Clustering – K-means algorithms, Clustering in non-Euclidean spaces, Clustering for streams and parallelism
  • Finding Frequent Item Sets – Handling large datasets in main memory, Counting frequent items in a stream
  • Finding Similar Items – Applications of near-neighbor search, Shingling of documents, Similarity-preserving summaries of sets, Locality sensitive hashing
