The main purpose of the research was to compare search engines performances in retrieving results for navigating querries. five search engines including Google, Yahoo, Bing, Ask, AOL were selected based on the Alexa rating scores. 011 questions in Persian along with the exact statement of question, a short description of information need, and the intended URLs were collected from the students. All 011 querries were searched in the selected search engines and the position of the correct results were recorded. For calculating the retrieving performance for the navigating querries several scales such as N success scale and reverse mean scores were used. Findings/ three search engines consisting Google, AOL, and Ask had somehow good results for navigating querries in Persian with the success rate of 364, 304, and 214, respectively. Nonetheless, Yahoo and Bing with 354 and 414 unsuccessful results had poor performances. Most results by Google, AOL, and Ask were retrieved in the first page.The search engines in 314 of cases were capable of retrieving requested items on the first page.

Ontology is an explicit formal specifications of the terms in the domain and relations among them. Ontologies are useful in medicine.Clinical decision support systems, medical expert systems, and biomedical databases are somehow related to ontologies. In this article we developed Iranian Medicinal Plants Ontology (IranMedPlantsOnt) based on Unified Medical Language System (UMLS).

The population of this descriptive survey was Iranian medicinal plants. Sample of this study was 2 plants chosen by theoretical sampling method. Also 2 books were chosen for extracting concepts and relations. In information extraction process, knowledge engineering approach was used. Also ontology building was based on the method proposed by Noy & McGuinness and Dumontier & Villanueva-Rosales using Protégé 4.2.beta. Findings/

We proposed 1 steps for medical ontology building in Persian. Determining the scope and domain of ontology, reusing of UMLS, extracting of concept pairs and mapping them to the UMLS, defining of classes, defining of properties, defining of facets and creation of instances are these seven steps. According to this study, UMLS is effective as a seed ontology for building Iranian medicinal plants ontology. Also the method proposed in this research can be used for building medical domain ontologies in Persian language.

This paper aims to investigate the publication output of the journal of Library and Information Science during the period of 2112-2102. Using scientometric approach, this paper studied the co-authorship network of authors by social network analysis measures. This paper investigates the topology features of co-authorship network of authors using some macro-level metrics like density, clustering coefficient, components as well as mean distance. It also focuses on the evaluation of the individual actors with the aim to capture the features of each author and centrality measures. The UCINET software was utilized for data analysis.Findings/ According to the findings, the most important and prolific authors in terms of both productivity and centrality measures are Rahmatollah Fattahi, Mohammad Hossein Dayyani, and Mehri Parirokh. The co-authorship network of the papers in this journal seems to exhibit ―small-world‖ as well as ―scale-free‖ network properties. Additionally, the famous idea of ―six degree of separation‖ can be valid in this network.

The aim of this study was to identify Factors affecting the adoption of electronic information resources (EIR) by Iranian Knowledge and Information Science (KIS) faculty members. A descriptive survey method was used as the research method.Findings/ The exploratory factor analysis showed that most important characteristics of electronic information resources (EIR) which can be effective in adopting electronic information resources were ―relative advantage‖, ―trialability‖, ―compatibility‖, ―complexity‖, ―observability‖, and ―opportunity of test‖. Further, the findings of Pearson correlation analysis showed that there was a significant relationship between the above six characteristics of EIR and adoption rate. The result of multiple regression analysis showed that the characteristics of ―observability‖, ―opportunity of test‖ and ―age‖, were significant predictors for the adoption of EIR, which in total; explain 21 percent variance of the dependent variable. This study confirmed The Rogers’ Diffusion of Innovation Theory (2113) in context of perceived characteristics of EIR, among faculty members in departments of knowledge and Information science in Iran.

the aim of the study is to assess the Iran ministries websites in view of the size of website (bytes), HTML errors frequency, accessing to various types of existing files, status of broken links, and also loading of the websites in special internet speed by W3 consortium online softwares. We used a survey analysis with webometric approach. The addresses of Iran ministries websites were imported in W3 consortium online softwares and then the status of the websites were surveyed. Findings/ results show that the status of Iran ministries websites was not satisfactory. The average time of websites for loading (waiting time) was 44.04 seconds in 56 kbps. The average frequency of the broken links was more than 41 numbers per websites. Also the rate of HTML errors was reported in high level (224 per website some of the factors have the most influence on users accessing the content of the websites, for example: contemporary using of various standards and with different editions of websites design programs by designers. Different types of the broken links caused decreasing of users surfing in middle of the websites pages. Also regarding the usual Internet speed in Iran, the accessing possess is difficult.

Getting access to relevant information in information databases and the World Wide Web is deemed as an important challenge in any IR system. the aim of this paper was to investigate the use of expert systems to improve retrieval ranking in Persian search engines. The query terms input by the user were processed by the IR system and the documents retrieved were listed based on their degree of similarity or relevance to the search terms. This type of sorting is of utmost importance to any IR system, and any mismatch in the sorting will result in failure of the user to get access to his/her information needs despite the availability of the data in the database. Findings/ The quality of the first 01 documents retrieved is crucial to the assessment of the relevant IR system. This paper intends to enhance, through the application of an expert system, the quality and efficiency of document retrieval in Persian databases search engines. The expert system computes the value and relevance of each article and hence outperforms traditional systems. This intelligent system transforms human parameters to expert system instructions and rules to assess the value of articles and, in practice, outperforms non-intelligent systems.

Academic library websites have an important role in information services to users.
