A survey of information retrieval and filtering methods
Christos Faloutsos, Douglas W. Oard · University Libraries (University of Maryland) · 1995
We survey the major techniques for information retrieval. In the first part, we provide an overview of the traditional ones (full text scanning, inversion, signature files and clustering). In the second part we discuss attempts to include semantic information (natural language processing, latent semantic indexing and neural networks). 1 Introduction This survey is divided in two parts. In the first part, we survey the traditional methods for text retrieval. There are two reasons for that: (a) knowledge of these methods is useful as the background information for the newer developments and (b) variations or extensions of these methods are in the heart of newer methods. Specifically, we examine full text scanning with recent developments on approximate searching; inversion-based methods, which are the fastest available and which will probably be used as the search engine in any information-retrieval system; methods using signature files; and methods using clustering, which is the tradit...
