EVALUATION OF INFORMATION RETRIEVAL SYSTEMS. Information Retrieval (IR) systems typically use an inverted text index to evaluate free-text queries. During indexing, most IR systems process each docu- ment separately, causing overlapping content to be indexed multiple times. This, in turn, leads to larger indexes that take longer to build and longer to query. In this paper, we describe a scheme where overlapping content is indexed just Journal-ref: Lorenzetti C.M., Caracterizaci\'on Formal y An\'alisis Emp\'irico de Mecanismos Incrementales de B\'usqueda basados en Contexto, 2011, PhD Thesis, Universidad Nacional del ….

    Text Information Retrieval Systems by Charles T. Meadow. Information retrieval and information filtering are different functions. Information retrieval is intended to support people who are actively seeking or searching for information, as in Internet searching. Information retrieval typically assumes a static or relatively static database against which, Information retrieval systems and, in particular, text retrieval systems are undoubtedly one of the most important methods for primary information processing. However, a strict, commonly accepted definition of a text retrieval system does not exist [1]. In this survey, a text retrieval system is assumed to be a system that meets user’s information need by pro-viding the user with certain.
