Abstract

Information retrieval is the computational discipline that deals with the efficient representation, organization, and access to information objects that represent natural language texts (Baeza-Yates, & Ribeiro-Neto, 1999; Salton & McGill, 1983; Witten, Mo√Ľat, & Bell, 1999). A crucial subproblem in the information retrieval area is the design and implementation of efficient data structures and algorithms for indexing and searching information objects that are vaguely described. In this article, we are going to present the latest developments in the indexing area by giving special emphasis to: data structures and algorithmic techniques for string manipulation, space efficient implementations, and compression techniques for efficient storage of information objects.
