Experiments in relevance weighting of search terms
Information Processing & Management, 1979Abstract Following successful initial tests of theoretically-based schemes for relevance weighting of search terms, further experiments were undertaken to validate these results. The experiments were designed to investigate weighting for a large document set, poor matching conditions, heterogeneous data, and limited relevance information, i.e.

Long‐term weight loss and weight‐loss maintenance strategies
Obesity Reviews, 2008SummaryIt has been suggested that about 20% of subjects undergoing weight‐loss programmes can achieve a certain degree of long‐term success. At present, surgery remains the only method resulting in long‐term sustained weight loss, but access remains restricted. Hence it is important to analyse, in addition to pharmacotherapy, the methods to improve the

Nonlinear transformation of term frequencies for term weighting in text categorization
Engineering Applications of Artificial Intelligence, 2012In automatic text categorization, the influence of features on the decision is set by the term weights which are conventionally computed as the product of term frequency and collection frequency factors. The raw form of term frequencies or their logarithmic forms are generally used as the term frequency factor whereas the leading collection frequency ...

Term weighting for information retrieval based on term’s discrimination power
Multimedia Tools and Applications, 2013One of the most important research topics in Information Retrieval is term weighting for document ranking and retrieval, such as TFIDF, BM25, etc. We propose a term weighting method that utilizes past retrieval results consisting of the queries that contain a particular term, retrieval documents, and their relevance judgments.

Global term weights in distributed environments
Information Processing & Management, 2008This paper examines the estimation of global term weights (such as IDF) in information retrieval scenarios where a global view on the collection is not available. In particular, the two options of either sampling documents or of using a reference corpus independent of the target retrieval collection are compared using standard IR test collections.
