In this paper, we analyze the behaviourat aspects of the previous extended boolean models and address important mathematical properties to affect retrieval effectiveness. ... The conventional boolean retrieval system does not provide ranked retrieval output because it cannot compute similarity coefficients between queries and documents. ... Although the fuzzy set model [1, 2, 3] , which is a logical extension of the boolean model, overcomes the problem of the conventional boolean retrieval system, it bassbeen criticized to generate incorrect ...doi:10.1007/978-1-4471-2099-5_19 dblp:conf/sigir/Lee94 fatcat:eozzldvbzfgj7fq2ojyedxhpgq
Whether using Boolean queries or ranking documents using document and term weights will result in better retrieval performance has been the subject of considerable discussion among document retrieval system ... The performance of information retrieval systems may be determined either by using experimental simulation, or through the application of analytic techniques that directly estimate the retrieval performance ... the performance of Boolean and term weighting systems. ...doi:10.1002/(sici)1097-4571(199702)48:2<143::aid-asi5>3.0.co;2-y fatcat:l6vk37ddvnbyppua4fkqfyhrhi
Certain recent advances in information retrieval research are then mentioned, including the formulation of new probabilistic retrieval models, and the development of automatic document analysis and Boolean ... Information retrieval components are currently incorporated in several types of information systems, including bibliographic retrieval systems, data base management systems and question-answering systems ...

systems using simple automated indexing has kept the linguistic focus of retrieval researchers on individual terms, usually assuming a “bag of terms” model. ... Chapter 3 addresses retrieval models, with one-third of the chapter addressing tradi- tional text retrieval models (Boolean, vec- tor, and probabilistic), one-third addressing “nonclassical” models that ...
