Keyword extraction attracts much attention for its significant role in various natural language processing tasks. While some existing methods for keyword extraction have considered using single type of semantic relatedness between words or inherent attributes of words, almost all of them ignore two important issues: 1) how to fuse multiple types of semantic relations between words into a unifor...

In recent years, many private corporations and government organizations have digitized corpuses of legacy paper documents. Often, these organizations hope to take advantage of digital representations to transform costly manual tasks associated with paper archives into less-costly computer-assisted tasks. The most common approach toward automated information extraction is through inverted indexi...

The paper is devoted to the analysis of problems appearing in optimisation and improvement of the powerbandwidth efficiency of digital communication feedback systems (FCS). There is shown that unlike digital systems, adaptive FCS with the analogue forward transmission allow full optimisation and derivation of optimal transmission-reception algorithm approaching their efficiency to the Shannon b...

This paper examines the differences between author generated keywords and automatically generated keywords in one area of scientific and technical literature. Using inverse frequency, keywords produced using both methods are examined using a maximum likelihood algorithm. By reducing the scope and size of the corpus of literature examined, this study more closely emulates the information gatheri...

ABSTRACT- Almost all oyster mushroom producers in Iran produce this kind of mushroom without any kind of casing soil. Although different kinds of casing soils are available for Agaricus bisporus, limited information is available regarding Pleurotus ostreatus. Availability of peat in many regions around the world is a concern and some researchers' efforts have been devoted to a search for altern...

Energy efficiency in buildings and facilities has become an important part of the efforts for reducing environmental pollution. In order to develop strategies for efficient allocation of energy resources aimed at reducing power consumption, certain electrical quantities needed for analysis must be measured and monitored. In this paper, we propose a low-cost architecture of the remote electrical...

In order to achieve the combined advantages of optical broadband network and wireless network, the concept of Fiber wireless (FiWi) access network has been evolved. There are various research issues in FiWi network. Survivability and energy efficiency are of main concern. In this paper the main objective is to propose optimal segmentation of FiWi network, using adaptive energy segmentation algo...
