A goodness of fit test approach in information retrieval

Kostas Fragos, Yannis Maistros
2006 Information retrieval (Boston)  
In many probabilistic modeling approaches to Information Retrieval e are interested in estimating how well a document model "fits" he user's information need (query model).  ...  This can be quantified by the so-called goodness of fit tests. In this paper, we present a new document ranking technique based on Chi-square goodness of fit tests.  ...  In many probabilistic modeling approaches to Information Retrieval e are interested in estimating how well a document model ``fits'' he user's information need (query model).  ...

Improving web database search incorporating users query information

Rakesh Rawat, Richi Nayak, Yuefeng Li
2011 Proceedings of the International Conference on Web Intelligence, Mining and Semantics - WIMS '11  
Due to the sheer size and volume of databases, retrieval of relevant information as needed by users has become a cumbersome process.  ...  This paper proposes a ranking algorithm that gives higher preference to a user's current search and also utilizes profile information in order to obtain the relevant results for a user's query.  ...  Good ranking of results as obtained from the test experiments in all such cases where users may have correctly classified their preferences for a query is a clear indicator of this approach.  ...

Emotional Image and Musical Information Retrieval With Interactive Genetic Algorithm

S.-B. Cho
2004 Proceedings of the IEEE  
It is expected that the same approach can be applied to many other problems in musical information retrieval and manipulation based on intuition and inspiration.  ...  To project the usefulness of the IGA to develop emotional human-computer interfaces, we have applied it to the problems of image and music information retrieval.  ...  However, there is no standard of the goodness of design, and it is almost impossible to organize the fitness function. IGA might be a solution in this case.  ...

A combined component approach for finding collection-adapted ranking functions based on genetic programming

Humberto Mossri de Almeida, Marcos André Gonçalves, Marco Cristo, Pável Calado
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
In contrast to related work, the GP terminals in our CCA are not based on simple statistical information of a document collection, but on meaningful, effective, and proven components.  ...  Experimental results show that our approach was able to outperform standard TF-IDF, BM25 and another GP-based approach in two different collections.  ...  [14] introduces a method of utilizing Genetic Algorithms in Information Retrieval tasks.  ...

Retrieval practice makes procedure from remembering: An automatization account of the testing effect

Mihály Racsmány, Ágnes Szőllősi, Dorottya Bencze
2018 Journal of Experimental Psychology. Learning, Memory and Cognition  
In 3 experiments, focusing on the reaction time (RT) of retrieval, we showed that RT of retrieval during retrieval practice followed a power function speed up that typically characterizes automaticity  ...  More important, it was found that the measure of goodness of fit to this power function was associated with long-term recall success.  ...  The measure of goodness of fit (sum of squared errors, SSE) showed a high rate of fit, SSE ϭ 0.004 ( Figure 2 ).  ...
