Assessing relevance and trust of the deep web sources and results based on inter-source agreement

Raju Balakrishnan, Subbarao Kambhampati, Manishkumar Jha
2013 ACM Transactions on the Web  
Secondly, the query based relevance does not consider the importance of the results and sources. These two considerations are essential for the deep web and open collections in general.  ...  We perform extensive evaluations on online and hundreds of Google Base sources spanning across domains. The proposed result and source rankings are implemented in the deep web search engine Factal.  ...  We deal with the problem of assessing trustworthiness and importance in the deep web by selecting sources based on their agreement; and extend the method for ranking the results returned by the sources  ...

Agreement Based Source Selection for the Multi-Domain Deep Web Integration

Manishkumar Jha, Raju Balakrishnan, Subbarao Kambhampati
2011 International Conference on Management of Data  
One immediate challenge in searching the deep web databases is source selection-i.e. selecting the most relevant web databases for answering a given query.  ...  For open collections like the deep web, the source selection must be sensitive to trustworthiness and importance of sources.  ...  A global relevance assessment based on the agreement of the results would thus have ranked the classic Godfather high.  ...

Assessing Information Quality of Wikipedia Articles through Google's E-A-T Model

Chinthani Sugandhika, Supunmali Ahangama
2022 IEEE Access  
Based on the empirical findings and study results, a set of IQ dimensions that influence the above three IQ constructs, as well as 45 IQ attributes to measure the IQ dimensions, were identified.  ...  Furthermore, an average inter-rater agreement of 84% was observed. Thus, the proposed model's effectiveness is fairly validated by this extensive experiment.  ...  INTER-RATER RELIABILITY TEST The authors adopted Fleiss-Davies Kappa [71] as the third evaluation technique. It measures the level of agreement (inter-rater reliability) between a set of raters.  ...
