Incorporating different search models into one document retrieval system

W. Bruce Croft
1981 Proceedings of the 4th annual international ACM SIGIR conference on Information storage and retrieval theoretical issues in information retrieval - SIGIR '81  
Many effective search strategies derived from different models are available for document retrieval systems. However, it does not appear that there is a single most effective strategy.  ...  One of the most desirable features of an adaptive system would be the ability to learn from experience. A method of incorporating this learning ability into the system is described.  ...  These techniques or search strategies, which are predominantly based on probabilistic models of document retrieval, include relevance weighting [1, 2, 3, 4] , relevance weighting modified to use term  ...

Combining structured and unstructured information in a retrieval model for accessing legislation

Marie-Francine Moens
2005 Proceedings of the 10th international conference on Artificial intelligence and law - ICAIL '05  
Such an approach is very promising for the retrieval of legal documents. This is illustrated with two retrieval models specifically designed for the retrieval of legislation.  ...  Current information retrieval research takes into account the structured information content of documents when computing the relevance ranking.  ...  The retrieval model of an information retrieval system is different from the one of a database system.  ...
