Introduction . Keywords, reflecting the main content of article, play an extremely important role in search for scientific papers databases. Together with title and abstract, keywords provide primary information about study. Selecting extracting effective is a time-consuming process, so its optimization requires further studying. Purpose. The article aimed at acquainting authors journal methods...

Feature selection study is gaining importance due to its contribution to save classification cost in terms of time and computation load. In search of essential features, one of the methods to search the features is via the decision tree. Decision tree act as an intermediate feature space inducer in order to choose essential features. In decision tree-based feature selection, some studies used d...

Current search engines with arrays of servers can provide efficient web content services. However, as their returned results are usually enormous mass, finding target information is still time-consuming. To increase the correctness of returned results, different page ranking methods were introduced. Some of them also try to use users’ feedback to increase their precision in ranking. However, as...

Routing in highly mobile, energy constrained wireless networks remains an open research area. The majority of energy aware protocols are designed for stationary networks, and conversely, mobile ad hoc protocols rarely incorporate information about node energy. Obtaining global information about energy distribution across the network is wasteful of scarce resources, so we introduce a ranking sys...

The problem of Order Acceptance and Scheduling (OAS) is defined as a joint decision of which orders to accept for processing and how to schedule them. Any linear programming model representing real-world situation involves the parameters defined by the decision maker in an uncertain way or by means of language statement. Fuzzy data can be used to incorporate vagueness in the real-life situation...

Many current recommender systems exploit textual annotations (tags) provided by users to retrieve and suggest online contents. The text-based recommendation provided by these systems could be enhanced (i) using unambiguous identifiers representative of tags and (ii) exploiting semantic relations among tags which are impossible to be discovered by traditional textual analysis. In this paper we c...

-The search engines, such as Google, Yahoo and Bing, provide a powerful information retrieval on the Web. A number of Web Mining algorithms, such as PageRank, Weighted PageRank and HITS, are commonly used to categorize and rank the search results. The motive behind this paper is to present and analyze the currently important algorithms for ranking of web pages such as PageRank and Weighted Page...
