the motivation of this paper is to propose such equitable method for ranking all decision making units (dmus) in dynamic data envelopment analysis (ddea) framework. as far as we are aware there is not more studies in dynamic dea literature. what's more, in such cases the best operating unit is important to be sampled for the others in under evaluated time periods. however, in this special conce...

nowadays energy is one of the most essential needs of human being and it can be considered as the basic prerequisite of social and economic development.  hence, many of the correlations and legislations of a country are affected by it. since iran has huge source of gas and oil, it has turned to a fossil fuel oriented county. but as oil and gas sources are non-renewable ones and cannot be replac...

The Web is a large collection of heterogeneous pages. Web documents are not always descriptive and accurate in content. In addition, a significant difference between the problems of Web search and traditional text search is the availability of hyperlinks between pages. A page on the Web might possibly be cited by or cite other pages. When evaluating a page, the neighborhood of the page might be...

In this chapter, we present our Top-N methods for extracting clusters of documents which have originated from the article (Haraguchi, 2002). We first discuss a method for pinpoint clustering of Web pages by pseudo-clique search (Haraguchi & Okubo, 2006; Okubo et al., 2005) and then a method for finding implicit page groups (clusters) represented as formal concepts (Li et al., 2008). A huge coll...

Open source software components implementing features of the ELECTRE and PROMETHEE family of MCDA procedures have been developed at Université Libre de Bruxelles and École Centrale Paris, as part of the Decision Deck project. As these procedures share several computation routines, they have been implemented as a set of independent components which can then be assembled in various ways. Care has...

Most existing search engines employ static ranking algorithms that do not adapt to the specific needs of users. Recently, some researchers have studied the use of clickthrough data to adapt a search engine’s ranking function. Clickthrough data indicate for each query the results that are clicked by users. As a kind of implicit relevance feedback information, clickthrough data can easily be coll...
