On the Role of Compensatory Operators in Fuzzy Result Merging for Metasearch [chapter]

Arijit De
2013 Lecture Notes in Computer Science  
In this work we study the role of applying fuzzy algebraic t-norms, s-norms and compensatory operators in fuzzy result merging for metasearch.  ...  Our results will demonstrate the superiority of compensatory operators over tnorm aggregation functions in the context of result merging for metasearch.  ...  The motivation of our work was to study how using compensatory operators, affects the result of merging result merging for metasearch. We build two models.  ...

ComRank: metasearch and automatic ranking of XML retrieval system

A. Woodley, S. Geva
2005 2005 International Conference on Cyberworlds (CW'05)  
The challenge of metasearch is to merge results lists from several IR systems, with the goal of outperforming each of the constituent systems.  ...  This is problematic for users since no one IR system works best for every scenario, and it is difficult for the user to know which system will work best a priori.  ...  Finally, the metasearch system merges the results lists, and returns the merged list back to the user.  ...

Web Information Personalization: Challenges and Approaches [chapter]

Cyrus Shahabi, Yi-Shin Chen
2003 Lecture Notes in Computer Science  
By focusing on these two types of systems, this paper reviews the challenges and the corresponding approaches proposed in the past ten years.  ...  Ideally, by merging various ranked results from multiple search engines into one final ranked list, metasearch systems could improve the retrieval rate.  ...  The second types of personalized metasearch systems [43, 44] emphasize on the merging procedures.  ...

These search engines are typically incompatible in that they support different query models and interfaces, they do not return enough information with the query results for adequate merging of the results  ...  Document sources are available everywhere, both within the internal networks of organizations and on the Internet.  ...  Example 9 shows one simple-minded way in which a metasearcher can re-rank documents from multiple query results.  ...

An application of the FIS-CRM model to the FISS metasearcher: Using fuzzy synonymy and fuzzy generality for representing concepts in documents

José A. Olivas, Pablo J. Garcés, Francisco P. Romero
2003 International Journal of Approximate Reasoning  
The model has been implemented in the FISS metasearcher (Fuzzy Interrelations and Synonymy based Searcher) that, using a soft-clustering algorithm (based on the SISC algorithm), dynamically produces a  ...  The readjustment lies on the study of two types of fuzzy interrelations between terms: the fuzzy synonymy interrelation and the fuzzy generality interrelations ("broader than" and "narrower than" interrelations  ...  The algorithm also consider merging clusters and removing documents for clusters when their average similarity decreases under the threshold.  ...

2009 Lecture Notes in Computer Science  
We use an extension of Ordered Weighted Average (OWA) operator called IOWA and a weighting schema, NOWA for merging the results.  ...  According to the idea behind metasearch engines, it seems that merging the results retrieved from different retrieval models will improve the search coverage and precision.  ...  We use OWA operator based on normal distribution weighting for merging the lists.  ...

Soft approaches to distributed information retrieval

Gloria Bordogna, Gabriella Pasi, R.R. Yager
2003 International Journal of Approximate Reasoning  
In both situations we have the problem of merging the results produced by the distinct IRS into a unique ordered list, which constitutes the unified answer to the user query.  ...  In this paper some fuzzy approaches to solve the two above-mentioned problems are presented.  ...  In the case of multi-source information retrieval the problem is to merge the lists resulting from the processing of the same query by (generally distinct) search engines on the distinct databases residing  ...

Vít Nováček, Pavel Smrž
2006 Lecture Notes in Computer Science  
This paper presents our research on uncertainty handling in automatically created ontologies. A new framework for uncertain information processing is proposed.  ...  The research is related to OLE (Ontology LEarning) -a project aimed at bottom-up generation and merging of domain-specific ontologies.  ...  Sample of the merged ontology Such a query can hardly be modelled in any classical logic. Nevertheless, it can be very useful -let us give one example for all.  ...
