Crimes against children : sexual violence and legal culture in New York City, 1880-1960 by S. E Robertson( Book )

7 editions published in 2005 in English and Undetermined and held by 343 WorldCat member libraries worldwide

In the first half of the twentieth century, Americans' intense concern with sex crimes against children led to a wave of public discussion, legislative action, and criminal prosecution. Stephen Robertson provides the first large-scale, long-term study of how American criminal courts dealt with the prosecution of sexual violence against children. Robertson describes how the nineteenth-century approach to childhood as a single phase of innocence began to shift at the end of the century to include several stages of childhood development, prompting reformers to create legal categories such as statutory rape and carnal abuse to protect children. However, while ordinary New Yorkers' involvement in the prosecution of those offenses reshaped their understandings of who was a child and produced a new concern to establish the age of their sexual partners, their beliefs in childhood innocence and in a concept of sexuality centered on sexual intercourse remained unchanged. As a result, families' use of the law and jurors' decisions ultimately diminished the protection the new laws offered to children. Robertson's study, based on the previously unexamined files of the New York County district attorney's office, reveals the importance of child sexuality and sex crimes in twentieth-century American culture

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 4 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
