Introduction to Information Retrieval: Concepts, Structures,
and Time Perspective
The purpose of this tutorial is to familiarize the audience with the concepts related to the implementation
of Information Retrieval Systems (IRSs). Topics to be covered include indexing, document representation, query
document matching, underlying file structures, user search practices, similarities and differences of IR and information
filtering systems, and performance evaluation. A time frame perspective of IRSs will also be provided.
Clustering for Information Retrieval: Techniques, Applications,
and Evaluation
Cluster analysis deals with automating a very human process: classifying objects into groups of similar
objects. From the viewpoint of information retrieval systems the objects are the documents that are relevant to
the same information need. The purpose of this tutorial is to present a comprehensive overview of the current research
on the use of clustering methods for information retrieval. After an introduction to the basic concepts, various
clustering algorithms are examined. Their implementation details, application areas, and evaluation methods are
provided.
