Query Propagation in Possibilistic Information Retrieval Networks
نویسندگان
چکیده
This paper proposes a new Information Retrieval Model based on possibility and necessity measures. This model encodes relationship dependencies existing between terms, documents and query by possibilistic networks. The user’s query triggers a propagation process to retrieve necessarily or at least possibly relevant documents.

A Model for Information Retrieval Based on Possibilistic Networks
This paper proposes a model for Information Retrieval (IR) based on possibilistic directed networks. Relations documents-terms and query-terms are modeled through possibility and necessity measures rather than a probability measure. The relevance value for the document given the query is measured by two degrees: the necessity and the possibility. More precisely, the user’s query triggers a prop...
متن کاملSaripod: a Possibilistic System for Web Information Retrieval
This paper presents a web information retrieval system based on Hierarchical Small-Worlds (HSW) and Possibilistic Networks (PN). The first HSW consists in structuring the "Google" search results in dense zones of web pages which strongly depend on each other. We thus reveal dense clouds of pages which "speak" more or less about the same subject and which all strongly answer the user’s query. Th...
متن کاملSaripod: a System Based on Hierarchical Small Worlds and Possibilistic Networks for Internet Information Retrieval
This paper presents an Internet information retrieval system based on Hierarchical Small-Worlds (HSW) and Possibilistic Networks (PN). The first HSW, for the words of the French language, is used to take account of the dependences between these words. The second HSW is devoted to the web pages required and translated in the same way the dependences between these pages. The PN generates the mixi...
متن کاملA Qualitative Approach for an Intelligent Possibilistic Web Information Retrieval using Multiagent System
As a long time as Internet will continue its evolution, we will continue to be submerged by data, without those however being structured. The search for information within this framework becomes a difficult task and the traditional methods of search on Internet or data bases prove more and more limited. The co-operative information systems based on the software agents bring promising solutions ...
متن کاملQEA: A New Systematic and Comprehensive Classification of Query Expansion Approaches
A major problem in information retrieval is the difficulty to define the information needs of user and on the other hand, when user offers your query there is a vast amount of information to retrieval. Different methods , therefore, have been suggested for query expansion which concerned with reconfiguring of query by increasing efficiency and improving the criterion accuracy in the information...
