Investigating text power in predicting semantic similarity
Get PDFThis article presents an empirical evaluation to investigate the distributional semantic power of abstract, body and full-text, as different text levels, in predicting the semantic similarity using a collection of open access articles from PubMed. The semantic similarity is measured based on two criteria namely, linear MeSH terms intersection and hierarchical MeSH terms distance. As such, a random sample of 200 queries and 20000 documents are selected from a test collection built on CITREC open source code. Sim Pack Java Library is used to calculate the textual and semantic similarities. The nDCG value corresponding to two of the semantic similarity criteria is calculated at three precision points. Finally, the nDCG values are compared by using the Friedman test to determine the power of each text level in predicting the semantic similarity. The results showed the effectiveness of the text in representing the semantic similarity in such a way that texts with maximum textual similarity are also shown to be 77% and 67% semantically similar in terms of linear and hierarchical criteria, respectively. Furthermore, the text length is found to be more effective in representing the hierarchical semantic compared to the linear one. Based on the findings, it is concluded that when the subjects are homogenous in the tree of knowledge, abstracts provide effective semantic capabilities, while in heterogeneous milieus, full-texts processing or knowledge bases is needed to acquire IR effectiveness
Internet Self-Efficacy and the Use of Electronic Information Services Acceptance
Get PDFSelf-efficacy and the use of electronic information services acceptance among the university students can affect the learners' online services. This is the due to the learners' acceptance of using technology and its role in their life. Therefore, the complexity of online and offline services needs to be examined by the experts to assess the learners'' satisfaction which helps them to achieve electronic services. Learners' self-efficacy management can be evaluated as an important issue in the present study. The present study aims at investigating the survey of the relationship between the internet self-efficacy and using the electronic information services among the university students of Dezful Islamic Azad University, Khuzestan, Iran. The present study was conducted through descriptive-analytical method and took a correlational approach. The study sample included 387 students. Smart Partial Least Squares (PLS) was applied to investigate the study conceptual model. The results indicated that the use of the internet among the university students significantly affected the electronic services application (β =0.182). The same significant effects were also found in the variables including web specific self-efficacy on the acceptability of use (β=0.285), perceived control on electronic services application (β=0.142), perceived control on the acceptability of use (β=0.139), interpersonal norms on the acceptability of use (β=0.376), attitudes on the acceptability of use (β=0.169),perceived usefulness on attitudes(β=0.224), perceived amusement on the attitudes(β=0.335), perceived risk on the attitude (β=0.187), and internet self-efficacy on the web-specific self-efficacy(β=0.672). However, it was also made clear that the effects of web-specific self-efficacy on the electronic services application (β=0.033), social norms on the acceptability of use (β=0.061), internet self-efficacy on attitudes (β=0.079) and social norms on attitudes (β=0.026) are not statistically significant. The universities can prepare and compile appropriate training programs to take effective steps in the acceptability of the internet use that is in line with making students more informed and aware of the electronic services
An Overview of Iran’s Public Libraries in 2025 Vision

So, different situations in three different years, namely, 2010, 2015, and 2025 have been compared by taking into account the indicators regarding 2025 vision document using related data taken from public libraries in each province separately. The findings show that the current situation of the five indicators studied in 2025 has significant difference compared with that of in 2015. Also a comparison between the current situation in 2015 and a past one in 2010 shows a significant difference and an increase in them in terms of three indicators, space, resources and employee. It should be mentioned that there are not a significant difference between these two years, 2010 and 2015, regarding two indicators, book borrowing and membership
Traditional Citation Indexes and Alternative Metrics of Readership
Get PDFThe present study aimed to investigate the relationship between traditional citation indexes representing hot papers in the field of “Clinical Medicine” and their bookmarking and readership in “Mendeley software”. The citation counts of hot papers were extracted from Essential Science Indicators (ESI) and Web of Science (WoS). As an applied research adopting a descriptive-exploratory method, the present study used the Essential Science Indicators to retrieve hot articles published between 2014 and 2016, indexed in the category “Medical Sciences”. Each record was then searched in Mendeley to obtain the number of readership of the paper and the academic status of the users. The results showed a significant positive correlation between Mendeley readership and citation indexes in both ESI and WoS. Moreover, the most frequently-cited articles in both databases attracted more readers in Mendeley than lowly-cited publications and both hypotheses were confirmed. Moreover, the findings revealed that Mendeley users had assigned a total number of 3847 tags to the hot papers, with the tags ranging in frequency from zero to 38 for individual articles. Compared with author keywords and Plus, about 10 percent of users’ tags were either meaningless or repetitive. The value of present study shows that “Mendeley Sofware” with the possibility of tagging articles, can be used to create a searchable folksonomy of information and as a source of data in information retrieval studies, help professionals to manage their literatures and make their research life easier
Identification, Extraction, Organization and Sharing of Personal Knowledge: Using Grounded Theory
Get PDFThis study aimed at evaluating the feasibility of identification, extraction, organization and sharing of personal knowledge of Kerman public librarians. This study was a qualitative one based on grounded theory. The research population consisted of all knowledge and information science experts in public libraries in Kerman and snowball sampling was used to select participants. In-depth interview was the data collection tool in this study. In order to ensure the validity and reliability of this research, Lincoln and Guba's evaluative criteria was adopted and data collected from the interview, were coded and analyzed. Personal knowledge is shared through group discussions, question and answer meetings with experts and elites or even sending an email to co-workers. Knowledge and information science experts in public libraries in Kerman have no definite tool to be always used by all for identifying of personal knowledge. The method of extraction of personal knowledge mostly depends upon the manner of organization of personal knowledge. Knowledge and information science experts’ success in personal knowledge management depends on letting out the knowledge available in their minds. In this regard, knowledge sharing which includes the dissemination or transfer of knowledge from one individual to a group or an organization is the fundamental factor for achieving goals and filling knowledge gaps in organizations. Therefore, it is the task of public libraries to promote the culture of personal knowledge sharing, create an encouraging and rewarding environment and establish trust among knowledge and information science experts at wor

A Useful Framework for Identification and Analysis of Different Query Expansion Approaches based on the Candidate Expansion Terms Extraction Methods
Get PDFQuery expansion is a method for improving retrieval performance by supplementing an original query with additional terms. This process improves the quality of search engine results and helps users to find the required information. In the recent years, different methods have been proposed in this area. In addition to such a variety of different approaches in this area and necessity of the study of their characteristics, the lack of a comprehensive classification based on candidate expansion terms extraction methods and also suitable and complete criteria to evaluate them, make the precise study, comparison and evaluation of methods for query expansion and choosing appropriate method based on need difficult for researchers. Therefore, in this paper a new useful framework is presented. In the proposed framework, in addition to the identification of three basic approaches based on the candidate expansion terms extraction methods for query expansion and expressing their properties, appropriate criteria for qualitative evaluation of these methods will be described. Next, the proposed approaches will be evaluated qualitatively based on these criteria. Using the systematic and structured framework proposed in this paper leads a useful platform for researchers to be provided for the comparative study of existing methods in the field, investigating their features specially their drawbacks to improve them and choosing appropriate method based on their needs
Synergy in the Iranian Innovation Systems at Regional and National Levels In the Triple-Helix Context
Get PDFThe synergies for the Iranian regional and national innovation systems among the geographical, technological and organizational distributions of firms were measured. Among the data of 87934 active industrial firms (December 2015), merely 46150 firms could be classified using NACE codes into high-tech, medium-tech and knowledge intensive sectors which in turn geographically divided into five regions. Accordingly, both the T0 and ΔTGTO of Iran at the national level had negative signs (-480.6 and -5.14 mbits, respectively), however all the ΔTGTOs in each separate region was highly positive denoting that national agglomeration significantly adds to the synergy in the system and a highly integrated national innovation system was proposed in Iran. Regions 1 (including Tehran as the capital) as well as region 4 (including Khuzestan which contains enormous oil and gas resources and industries) caused less disturbance to the national synergy compared with the other three regions (ΔTGTOs= +18.1 and +22.2 mbits, respectively). The decomposition of sectorial technologies showed that in contrast to many other countries, especially for west European countries, high-tech manufacturing and knowledge intensive services were the main drives of knowledge-based configuration in the regional economy of Iran, while medium-tech manufacturing tend to uncouple the economy from the regional configuratio
Designing a New Model for Organizational Websites Evaluation
Get PDFThe current web evaluation models are mainly based on the technical evaluation of the site and its appearance and usability from user's perspective. In other words, the site is evaluated as an independent entity from the underlying organization that it represents. The focus of this study is on evaluation of organizations' websites based on the quality management concepts. In this way, the measured performance indicators will be used to find the deficiencies of the websites and recommend corrections. For evaluating the organization’s success in its website function, the concept of quality management is used and since evaluation and improvement are the center of attention in this model, the model is called Ev-Imp, which Ev stands for evaluation and Imp stands for improvement. Model includes four main components consist of objectives, processes, criteria and feedback. With the use of feedback tools such as quantitative and qualitative questionnaire for groups of stakeholders and service providers ,the website’s weaknesses and strengths would be identified and with analyzing the website’s weaknesses required improvement would be determined and corrective action would be don
