A probabilistic model of information retrieval : development and status by Karen Sparck Jones( Book )

2 editions published in 1998 in English and held by 7 WorldCat member libraries worldwide

Abstract: "The paper combines a comprehensive account of the probabilistic model of retrieval with new systematic experiments on TREC Programme material. It presents the model from its foundations through its logical development to cover more aspects of retrieval data and a wider range of system functions. Each step in the argument is matched by comparative retrieval tests, to provide a single coherent account of a major line of research. The experiments demonstrate, for a large test collection, that the probabilistic model is effective and robust, and that it responds appropriately, with major improvements in performance, to key features of retrieval situations."
Simple, proven approaches to text retrieval by S. E Robertson( Book )

3 editions published between 1994 and 1998 in English and held by 6 WorldCat member libraries worldwide

Abstract: "This technical note describes straightforward techniques for document indexing and retrieval that have been solidly established through extensive testing and are easy to apply. They are useful for many different types of text material, are viable for very large files, and have the advantage that they do not require special skills or training for searching, but are easy for end users."

The Probabilistic Relevance Framework : BM25 and beyond by S. E Robertson( Book )

6 editions published in 2009 in English and held by 3 WorldCat member libraries worldwide

The Probabilistic Relevance Framework (PRF) is a formal framework for document retrieval, grounded in work done in the 1970-80s, which led to the development of one of the most successful text-retrieval algorithms, BM25. In recent years, research in the PRF has yielded new retrieval models capable of taking into account document metadata (especially structure and link-graph information). Again, this has led to one of the most successful web-search and corporate-search algorithms, BM25F. This work presents the PRF from a conceptual point of view, describing the probabilistic modelling assumptions behind the framework and the different ranking algorithms that result from its application: the binary independence model, relevance feedback models, BM25, BM25F. It also discusses the relation between the PRF and other statistical models for IR, and covers some related topics, such as the use of non-textual features, and parameter optimisation for models with free parameters
