Fuzzy requests: An approach to weighted boolean searches
TLDR
The problem of how to permit a patron to represent the relative importance of various index terms in a Boolean request while retaining the desirable properties of a Boolean system is concerned.Abstract:
This article concerns the problem of how to permit a patron to represent the relative importance of various index terms in a Boolean request while retaining the desirable properties of a Boolean system. The character of classical Boolean systems is reviewed and related to the notion of fuzzy sets. The fuzzy set concept then forms the basis of the concept of a fuzzy request in which weights are assigned to index terms. The properties of such a system are discussed, and it is shown that such systems retain the manipulability of traditional Boolean requests.read more

Extended Boolean information retrieval
TL;DR: A new, extended Boolean information retrieval system is introduced which is intermediate between the Boolean system of query processing and the vector processing model, and Laboratory tests indicate that the extended system produces better retrieval output than either the Boolean or thevector processing systems.

Developments in automatic text retrieval.
TL;DR: The text analysis problem is examined, and modern approaches leading to the identification and retrieval of selected text items in response to search requests are discussed.

Adaptive ranking system for information retrieval
TL;DR: In this paper, an adaptive record ranking method for full text information retrieval, which quantifies the relevance of retrieved records to query terms occurring in said record, is proposed, which utilizes a multilevel weighting technique which permits user input to affect record weighting at each level of the ranking process.

A Fuzzy Linguistic Approach Generalizing Boolean Information Retrieval: a Model and its Evaluation
Gloria Bordogna,Gabriella Pasi +1 more
TL;DR: A fuzzy linguistic model is defined, starting from an existing weighted Boolean retrieval model, a linguistic extension, formalized within fuzzy set theory, in which numeric query weights are replaced by linguistic descriptors which specify the degree of importance of the terms.

System for ranking the relevance of information objects accessed by computer users
TL;DR: In this paper, a user profile of interests is stored for each user having access to the system and items of information to be presented to a user are ranked according to their likely degree of relevance to that user and displayed in order of ranking.

TL;DR: Criteria are given for the functions used to evaluate the relevance of the records to a specific query, including self-consistency, as a generalization of a Boolean retrieval system.

A fuzzy model of document retrieval systems
TL;DR: To deal with the organization problems of data in this conceptual model, the conventional concept of a list is extended to a fuzzy list and the notion of an inverted file structure can be extended to the fuzzy data in the retrieval model.

Automatic ranked output from boolean searches in SIRE
TL;DR: The study found that relevant documents were ranked significantly higher than nonrelevant documents in the set of documents retrieved in response to a Boolean query.
