The purpose of this paper is to investigate image search and retrieval problems in selected search engines in relation to Persian writing style challenges.

This study is an applied one, and to answer the questions the authors used an evaluative research method. The aim of the research is to explore the morphological and semantic problems of Persian language in connection with image search and retrieval among the three major and widespread search engines: Google, Yahoo and Bing. In order to collect the data, a checklist designed by the researcher was used and then the data were analyzed by descriptive and inferential statistics.

The results indicate that Google, Yahoo and Bing search engines do not pay enough attention to morphological and semantic features of Persian language in image search and retrieval. This research reveals that six groups of Persian language features include derived words, derived/compound words, Persian and Arabic Plural words, use of dotted T and the use of spoken language and polysemy, which are the major problems in this area. In addition, the results suggest that Google is the best search engine of all in terms of compatibility with Persian language features.

This study investigated some new aspects of the above-mentioned subject through combining morphological and semantic aspects of Persian language with image search and retrieval. Therefore, this study is an interdisciplinary research, the results of which would help both to offer some solutions and to carry out similar research on this subject area. This study will also fill a gap in research studies conducted so far in this area in Farsi language, especially in image search and retrieval. Moreover, findings of this study can help to bridge the gap between the user’s questions and search engines (systems) retrievals. In addition, the methodology of this paper provides a framework for further research on image search and retrieval in databases and search engines.

This study aims to evaluate the selected children’s websites in terms of information visualization features based on the criteria existing in the related literature and expert scrutiny.

A mixed-methods (qualitative-quantitative) study was conducted with a descriptive-comparative approach. A set of 80 English websites, as well as 24 quality Persian websites, were selected constituting a sample size of 104 websites. A conceptual model was developed from an extensive literature review on information visualization in children’s websites. In the quantitative part, a checklist derived from the conceptual model and based on the heuristic evaluation method was distributed among 20 related experts, the data of which were then analysed through Partial Least Squares using SmartPLS 3.0.

Confirmatory factor analysis showed high-reliability indicators and fit indices in measurement and structural models showing that the conceptual model had the necessary validities among the expert evaluators. Path coefficients showed that layout design and user interface design were the first and last priorities among the dimensions. It was also found that English websites were much more successful than Persian websites in supporting the features of information visualization.

The current study has implications for the effective use of standard features related to information visualization in children’s websites usable for designers, media specialists, parents, instructors and librarians, which would also make the children more engaged to better use, learn and interact with the websites.

The aim of this study is to compare the situation of internet resource citations in scientific articles of the journals of Shahid Beheshti University of Medical Sciences from 2005‐2009.

The research method is an analytical survey with webometrics and citation analysis. The internet was used as a tool for accessing articles. They are separately analyzed on the basis of journal name and publication year. The analysis is done using MATLAB and Excel software.

A total of 717 articles from seven journals during five years were reviewed. Of 13,448 citations extracted, 120 internet references were found. The final results indicated that the sum of web citations is less than 1 per cent of total citations and only 52 per cent of internet citations in studied journal articles are available. The average half‐life for the medical journals is estimated to be 1.02 years.

To increase the rate of URLs availability, publishers should oblige authors to utilize online archives such as WebCite to preserve expected information for all of the citations referred to in their articles.

This research would be valuable since it is the first that studies stability and persistence of URL domains of medical journals published in Shahid Beheshti University of Medical Sciences according to type of domain names and file extensions. Moreover, this is the first time that the half‐life for medical universities web citations is calculated.

The present study aims to review the literature concerning Digital Libraries (DLs) and user interfaces in order to identify, determine, and suggest evaluation criteria for a DLs user interface. Accordingly, this study's objectives are threefold: explore which criteria exert a significant relationship with the DLs user interface; identify a set of criteria that appears to be useful for evaluating DLs user interface; and determine evaluation criteria that have more frequency and occurrence in the related texts reviewed.

To do it, first, identifying related texts was necessary. Consequently, keywords such as “DLs user interface evaluation”,” DLs user interfaces”, “DLs evaluation”, “DLs usability”, “user interface evaluation”, “DLs research”, “web sites user interface evaluation”, “user interface standards”, and the like have been searched in the web as well as in some leading databases including Emerald, Proquest, SagePub, ScienceDirect, LISA, ERIC, ACM, and Springer. After identifying and accessing more than 100 evaluative works and some related articles, theoretical and empirical, nearly 50 sources were chosen for final examination.

After reviewing related texts, three major categories are identified: user interface and DLs; DLs and usability; and other studies related to user interface; each one of three identified categories has its own subcategories. Additionally, 22 evaluation criteria for assessing DLs interface have been identified.

The review does not claim to be comprehensive.

Hopefully, criteria such as feedback, ease of use, match between system and the real world, customization, user support, user workload, interaction, compatibility, visibility of system status, user experience, flexibility, and accessibility which have been less considered should be applied more in future, particularly user‐oriented, studies. Furthermore, it is expected that criteria mentioned here could help related bodies pay more attention to the evaluation of EISs, especially DLs interface.

It can be said that this study has contributed to the research into the evaluation of DL interface.
