Get PDFUsing indicators and statistics of ISI, this paper comparatively evaluates Iran indexed scientific productions from 1993 through 2007. Considering the number of indexed scientific productions in WOS, Iran was in a satisfactory position in terms of the growth rate. According to the statistics of ESI, Iran was in the second place after Turkey among Islamic countries and the fortieth in the world, during the last ten years. Most of the scientific productions of Iran were published in English "article" formats. According to JCR statistics, three Iranian Journals in 2005 were indexed in SCI section of this database and three more journals were added to it in 2006. Shiraz University has had the most journals in JCR in 2006
Bibliometric Analysis as Part of a Trend Recognition System in Science
No full textThis study aims to describe the way in which bibliometric analysis can become a trend recognition tool. The research work shows the application of bibliometric analysis in science. Such analyses provide information about the response received by scientific publications. The paper indicates how, with the aid of a tripartite division, it becomes possible to examine the past, present and future. For the past, it is above all the scientific output that is examined, for the present the response to this output is considered, and for the future perspective future fields are defined which provide information about this aspect. Indicators are introduced for each of the above-mentioned perspectives and the way these indicators are established is explained. With respect to the perspective of future fields, this involves investigating the interdisciplinarity of scientific publications. Bibliometrics is associated with methods of information management. These methods include, for example, critical success factors for trend recognition. A workflow additionally describes in four steps the different activities necessary for achieving the goal of trend recognition. Consideration is also given to possible forms of trends and how they are to be dealt with. The study concludes that it is possible to perform trend recognition by bibliometric methods
Assessment of Service Quality at Central Library of Management and Planning Organization (MPO), Iran
Get PDFThis study examines the quality of services at Iran’s Central Library of Management and Planning Organization (MPO) from the viewpoint of itsusers. The research was conducted in two phases: First, the library and its services were compared to the Standards for Special Libraries published bythe National Library of Iran (NLI). The library was found to meet most of the standards. Second, the quality of service provided by the library atexpected and observed levels was examined from the viewpoint of organizational and non-organizational members using a modified version ofthe SERVQUAL questionnaire. Findings showed a significant was difference between two (expected and observed) levels, meaning that users’expectations have not been met. The most significant difference related to “appropriate collection of information resources”. The results also showedthere was no significant difference between organizational and non-organizational users’ opinions about the quality of services. Findingsalso showed that “relevant information services” was the priority of user groups-users emphasized the need for timely and accurate information.There was a correlation between the rate at which the library conformed to the national standards and users’ expectations of quality
Squash: Design and Implementation of a Large Scale Http Gateway and Masquerader
No full textInformation available on the web can be divided in two main categories. The first category is those information distributed among different websites and servers. The second category is the information gathered in central information databases (infobases) which contain a huge amount of information and are available and searchable through the website representing the infobase. Infobase owners sell information to the users on per request basis, or to larger groups, based on the number of needed resources. Authentication is done in one of two ways, or both of them: username/password and IP-based. The first approach has so many practicial problems so, in this paper a new approach has been proposed based on central system as an access-point and gateway for users to receive and retrieve their information using Squash technology. The architecture and advantages of this novel method have been discussed and the way of implementation has been described
Does Simple Binary Crossover Hasten RCGA Convergence?
No full textReal Coded Genetic Algorithm, RCGA, is the type of GA which operates on chromosomes with real valued parameters. Different mutation and crossover operations are defined for RCGA. One usable crossover for this kind of GA is to consider its chromosomes simply as bit strings and utilize the same operations as Binary Coded GA. In this paper, we attempt to show that this kind of crossover can not hasten the convergence process unless the break points fall at the boundaries of parameters in the chromosome
A Statistical Study on Persian Subject Headings Development
Get PDFControlled vocabularies have been frequently used in information retrieval systems. Control of the vocabularies and evaluating the utility of their terms are two critical questions. This research aims at the development of Persian subject headings through statistical analyses. The current research was conducted on more than 450,000 records extracted from the electronic version of National Bibliography of Iran (NBI). Data has been processed through data mining techniques. The correlation analysis was performed to determine the relationship between the number of items in NBI and the number of Persian subject headings as well as the rank of each subject heading and its use frequency in NBI.The count of new subject headings vs. the count of new catalogued materials in NBI grew linearly at the beginning and increased logarithmically when the number of catalogued materials reached 3,200. The analysis of the use frequency of distinct headings within NBI resulted in three classes: most, frequent, and normal used subject headings. The findings partly agree with Lancaster’s prediction, as he states that a controlled vocabulary will grow very fast in the beginning. It was also found that the majority of subject headings are rarely used by NBI. It is due to absence of a mechanism to control the building of new headings
GLOBALIZATION AND E-BUSINESS
No full textThe attempts of globalization in developing countries could be observed in a wide range of areas. Objectively speaking, globalization can be of advantage to developed and developing countries provided that the compaines and commodities of those countries can get access to and compete with those of others in international market place as equal partners with fairness in international trade. Globalization is not just liberalization of trade, opening up borders by lowering or removing tariffs and non-tariffs barriers, but it goes beyond and tries ideally to generate a business in production, investment, financing, marketing and distribution as well as in organization, management and supervision by a universal code of conduct. On the other hand, with the expansion of satellite communication, computer net-works, and reducing the transportation costs, the process of globalization is becoming easier, and with the aid of e-banking, Electronic Commerce has replaced the traditional trade system. Moreover, globalization refers to the widespread distribution of networking mechanisms and the accessibility of them to all parties, no matter where they live. It is a difficult stage that requires conscious decision making and can only be developed step-by-step[1]. This paper attempts to review the impact of Globalization and E-Business in the new Millennium, especially in the steel industry. To put it another way, it reviews cost savings that can be achieved through E-Commerce in a global market. Certain recommendations are also made for designing startegies to increase the profit rate as well as the share of E-Business in the market in the long run
New Capital Budgeting Theory: As a New Management Information System Tool
No full textThe purpose of this paper is to review the real options literature, which has provided a promising area of development in the capital budgeting process of the firm, and to emphasize that employing the new theory, as part of the information system, depends heavily on the implementation of computer information systems, as Decisions Support Systems (DSSs). The paper concentrates on two important real options: to wait and to abandon. It is shown that in absence of the real option values in the capital decision making models, the outcome of such models would be misleading and would lead to wrong decisions. The paper furnishes some avenues for further research in capital budgeting employing real option literature
Evaluating Function of Persian Search Engines on the Web Using Correspondence Analysis
Get PDFThis study aimed to evaluate Persian Search Engines based on the criteria obtained from Alexa databank using correspondence analysis. Through searching the web, 23 search engines were found, which due to their cease and no coverage by Alexa, this number was reduced to 16. Data analysis revealed that Ghatreh Search Engine occupied a high rank in most of attributes like traffic rank, time spent on site and number of pages viewed per user. Iranmania Search Engine attained the largest number of links among other search engines. Jostejoogar Search Engine attracted the largest number of foreign users whilst Begardim Search Engine had no foreign users. Correspondence analysis classified the 16 search engines into three groupings which were related on the basis of certain attributes
Computational analysis of optimisation algorithms with artificial intelligence
No full textArtificial intelligence is a way of making a computer behave 'intelligently'. This can be accomplished by: studying how people think when they are trying to make decisions and solve problems; breaking those thought processes down into basic steps, and finally designing a computer program that solves problems using those same steps. AI thereby provides a simple, structured approach to designing complex decision making programs. The goal of an AI system is to analyse human behaviour in the fields of perception, comprehension and decision making with the ultimate hope of reproducing the behaviour on a machine, namely a computer. One major category of AI techniques is 'genetic algorithm'. Although it is recognised that the performance of an evolutionary system such as GA is affected by the parameters that are employed to implement them, there is hardly any work known to us that has shed much light on the interdependencies and interactions between these parameters. Most studies on the effects of these parameters on performance of GA-based systems have focused on a parameter, at a time, without considering the effect of other parameters on that parameter and vice versa. Consequently, there is hardly any theory about the interactions and interdependencies of these parameters. This paper contributes towards correcting the situation mentioned above by examining empirically the relationship between three parameters of GAs
