On the evaluation of Boolean operators in the extended Boolean retrieval framework

Joon Ho Lee, Won Yong Kin, Myoung Ho Kim, Yoon Joon Lee
1993 Proceedings of the 16th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '93  
The retrieval models based on the extended boolean retrieval framework, e.g., the fuzzy set model and the extended boolean model have been proposed in the past to provide the conventional boolean retrievat  ...  In this paper we first investigate the behavioral aspects of the fuzzy operators and address important issues to affect retrieval effectiveness.  ...  The Operators of the Extended Boolean Model The extended boolean model has overcome the single operand dependency problem of the fuzzy set model by developing the EM and Eo~operators for the evaluation  ...

Neural Networks Retrieving Boolean Patterns in a Sea of Gaussian Ones

Elena Agliari, Adriano Barra, Chiara Longo, Daniele Tantari
2017 Journal of statistical physics  
Assuming replica symmetry, we study the case of a low load of Boolean patterns combining the stochastic stability and Hamilton-Jacobi interpolating techniques.  ...  We prove that, in the challenging regime of a high storage of real patterns, where retrieval is forbidden, an extra load of Boolean patterns can still be retrieved, as long as the ratio among the overall  ...  Note that a fairly standard usage of the replica-trick allows to extend the previous result to the case of a high load of boolean patterns too.  ...

Hybrid Term Indexing: an Evaluation

Robert W. P. Luk, Kam-Fai Wong, K. L. Kwok
2001 NTCIR Conference on Evaluation of Information Access Technologies  
Here, we extended the vector space model using the cosine measure, for processing hybrid terms. We also introduced weighting based on the length of the term.  ...  Ranking based on the length of the query terms slightly improves the retrieval effectiveness of hybrid term indexing but degrades the retrieval effectiveness of word indexing.  ...  We thank the Center for Intelligent Information Retrieval, UMASS, for providing the computing facility to carry out the evaluation.  ...

Using pattern structures to support information retrieval with Formal Concept Analysis

Víctor Codocedo, Ioanna Lykourentzou, Hernán Astudillo, Amedeo Napoli
2013 International Joint Conference on Artificial Intelligence  
The use of concept lattices to support the task of document retrieval in IR has proven effective since they allow querying in the space of terms modelled by concept intents and navigation in the space  ...  of documents modelled by concept extents.  ...  Boolean operators in the query were ignored since they do not provide meaning in the vectorspace model (except in the extended Boolean model case [17] not considered in this work).  ...
