A Logical Relational Approach for Information Retrieval Indexing

Iadh Ounis, Theo Huibers
1997 unpublished
In a relational indexing approach (see e.g. Farradane's work), information is carried by a fixed set of relationship types over an underlying set of terms.  ...  For instance the field of logic-based information retrieval [1, 2, 3, 4] is broadening rapidly as a theoretical framework for studying information retrieval.  ...  A logical relational approach Suppose one wants to build a logical system for a given application.  ...

Negations and Document Length in Logical Retrieval [chapter]

David E. Losada, Alvaro Barreiro
2004 Lecture Notes in Computer Science  
A simple logical indexing process capable of expressing negated terms and omitting some other terms in the representation of a document was designed.  ...  A propositional model of information retrieval is used to exemplify the advantages from such expressive modeling. A number of experiments applying these partial representations are reported.  ...  For bins #1 to #100 the dl indexing approach retrieves documents with higher probability than the cwa approach.  ...

2009 Conference and Labs of the Evaluation Forum  
This work is an extension to those experiments which focuses on building a framework for cross language information retrieval.  ...  In this paper the application of the theory of Human Plausible Reasoning (HPR) has been investigated in the domain of filtering and cross language information retrieval.  ...  Once the direct approach is applied on the new term c document doc#3 is retrieved as a related document to the query.  ...

Integrating symbolic images into a multimedia database system using classification and abstraction approaches

Aya Soffer, Hanan Samet
1998 The VLDB journal  
Di erent strategies for image retrieval for a numb e r o f t ypical queries using these approaches are described. Estimated costs are derived for these strategies.  ...  Spatial constraints may be based on both locational information e.g., distance and relational information e.g., north of.  ...  An index mechanism based on the logical representation can then be used to retrieve images based on both contextual and spatial locational and relational information in an e cient w a y .  ...
