Research Evaluation Systems (RESs) can be divided into “pre-performance or post-performance evaluation” or “retrospective or prospective evaluation”. The Retrospective Research Evaluation Systems (RRESs), also known as Performance-based Research Funding Systems (PRFSs), are complex national systems designed to evaluate universities and research centers and allocate public funds based on their outputs and outcomes. This study compares the RRESs of the UK and Australia to gain a better understanding of the structure and components of these evaluation systems. A comparative study method was applied to look for similarities and differences between the RESs of selected countries. The two countries were chosen based on the criteria of transparency, access to credible documents, formality, comprehensiveness, flexibility, and management. Bereday's four-step model consisting of description, interpretation, juxtaposition, and comparison of RESs was utilized for the data analysis. The results showed that two evaluation systems emphasize the components of human resources, finance and infrastructure in evaluation. Quantitative and qualitative approaches prevail in all two systems. In terms of the evaluation unit, the systems have almost the same structure, and the evaluation is done by specialized panels. The quality of research outputs is evaluated in two systems, and in the UK, the two elements of impact and research environment are also evaluated. In general, it can be said that the formation of national systems for research evaluation affects not only the quality of research, but also the purposefulness of research, scientific and technical progress of the country, and people's lives. The unique aspect of this study is the comparison of the input, process, output, and impact components of the RRESs of the UK and Australia. The results can be beneficiary for managing and policymaking for research assessment units on micro/macro levels. © (2025), (Phcog.Net). All rights reserved.

Current search engines for Knowledge Retrieval (KR) and Knowledge Discovery (KD) do not effectively utilize scientifically validated documents, especially those indexed in scientific databases. Scientific databases e.g., Scopus primarily consist of document-based content and provide documents' abstract. Their Information Retrieval (IR) system only perform document searches and lack the capability to extract and discover new knowledge from documents' abstract in these databases and responding to users’ queries. The aim is to introduce a model that can efficiently perform these tasks. The statistical population for this study encompasses all scientific databases, with a particular emphasis on Scopus. To clarify the process of KR and KD as we define it, we employed a systematic review and meta-analysis framework using 33 queries. We conducted the identification, screening, eligibility, and inclusion steps following the PRISMA protocol. Next, we performed extraction, labeling, grouping, analysis, and inference. The outcome of these processes provided us with novel insights, which contribute to our exploratory knowledge. To automate these processes, we have proposed a conceptual model from query-based indirect abstractive summarization approach. The outcomes of this research offer fresh insights to database designers, administrators, and researchers, enabling the development of tools for KR and KD within these invaluable knowledge repositories. The integration of such tools into scientific databases will enhance user access to scientific knowledge to meet their informational and research needs. © 2025 The Authors

This study has developed a combined indicator to evaluate the performance of different search engines. Documentary analysis, survey, and evaluative methods are employed in the present study. The research was conducted in two stages. First, a combined indicator was designed to measure search engines. To this end, 72 criteria for measuring the performance of search engines were identified, out of which 22 criteria were selected. Accordingly, 10 criteria were selected in six general classes through a survey of subject matter experts. Validation of our proposed combined indicator was obtained by Delphi method and using the opinions of experts in the fields of information science and information system. Second, web search engines were evaluated based on the proposed combined indicator. The statistical population of this part of the research consisted of two categories: (1) general web search engines, and (2) general subjects. The sample size of the first category contained four search engines Yahoo, Google, DuckDuckGo, and Bing, and the second category involved 40 search terms under 10 general categories. The results showed that the combined indicator had six general criteria: (1) relevance, (2) ranking, (3) novelty ratio, (4) coverage ratio, (5) ratio of unrelated documents, and (6) proportion of duplication hits. According to this indicator, Google is at the top, followed by Bing. This study proposes a new indicator for evaluating search engine performance, which can measure the efficiency of search engines. Therefore, its use to measure the performance of search engines is recommended to researchers and search engine developers. © The Author(s) 2022.

The general subject trends and emphasized points of Community Librarianship (CL) researches are not clear. According to reviewed papers, CL encompasses a wide range of social issues. This dispersion and diversity require presenting a comprehensive map of the thematic trends. The present study showed the concept of “social capital” is the underlying base for the literature of CL, which is the outcome of dialogue and interactive space of libraries. Also, historically, the related publications can be classified into five categories: 1) promoting the democratic culture and training informed and participating citizens 2) improving e-government; 3) library as a place for creating social capital; 4) sharing consumer health information; and 5) natural crises and disasters. The results of this study can show and reflect the “common good” of public libraries, that can effectively provide insight for librarians, attract policymakers’ support, and maintain the position and future of these libraries. © 2024 The Author(s).

Many organizations and businesses are using futurology to keep pace with the ever-increasing changes in the world, as the businesses and organizations need to be updated to achieve organizational and business growth and development. A review of the previous studies has shown that no systematic research has been already conducted on the future of information retrieval systems and the role of library and information science experts in the future of such systems. Therefore, a qualitative study was conducted by reviewing resources, consulting experts, doing interaction analysis, and writing scenarios. The results demonstrated 13 key factors affecting the future of information retrieval systems in the form of two driving forces of social determinism and technological determinism, and four scenarios of Canopus star, Ursa major, Ursa minor, and single star. The results also showed the dominance of technology and social demand and its very important role in the future of information retrieval systems. © The Author(s) 2022.

This experimental study used a checklist to evaluate the performance of seven search engines consisting of four Image General Search Engines (IGSEs) (namely, Google, Yahoo DuckDuckGo and Bing), and three Image Specialized Search Engines (ISSEs) (namely, Flicker, PicSearch, and GettyImages) in image retrieval. The findings indicated that the recall average of Image General Search Engines and Image Specialized Search Engines was found to be 76.32% and 24/51% with the precision average of 82/08% and 32/21%, respectively. As the results showed, Yahoo, Google and DuckDuckGo ranked at the top in image retrieval with no significant difference. However, a remarkable superiority with almost 50% difference was observed between the general and specialized image search engines. It was also found that an intense competition existed between Google, Yahoo and DuckDuckGo in image retrieval. The overall results can provide valuable insights for new search engine designers and users in choosing the appropriate search engines for image retrieval. Moreover, the results obtained through the applied equations could be used in assessing and evaluating other search tools, including search engines. © The Author(s) 2021.

Background: Detecting the main actors and important topics of Iranian cancer research is essential for Iranian policymakers, clinicians, and researchers. This study was conducted to demonstrate the trends and tops in Iranian cancer research from 1960 to 2018. Methods: A total of 22,370 Iranian cancer articles in Web of Science (WoS), PubMed, and Scopus, from 1960 through 2018, were extracted and preprocessed based on data mining techniques and analyzed using the collaboration network analysis, keywords analysis, and bibliometrics methods. Results: The results reveal that, Tehran University of Medical Sciences (11.46%) among organizations, Asian Pacific Journal of Cancer Prevention (5%) among journals, Malekzadeh R (1.09%) among authors, and Breast cancer (10.37%) among topics ranked the first. The trend of Iranian cancer research represents three periods: 1) germinating period, from 1970 to 2000, 2) developing period, from 2002 to 2014, and 3) flourishing period, from 2014 to 2018. It is expected that this trend will continue. The results indicate an average 12.8% increase in the logarithm of the count of articles published by Iranian cancer researchers each year. The findings are contextualized with Price's publications trends principal for determining global and Iranian cancer research publication trends. Conclusion: The number of research papers published by Iranian researchers on cancer is increasing. In order to maintain the publication growth in this field, greater participation by other Iranian institutions is suggested. Although the quantity and quality of papers are increasing in some topics, certain topics and types of cancers should be still further studied and the Iranian policymakers should be encouraged to invest more in these topics. © 2022 Academy of Medical Sciences of I.R.

The purpose of this research is to develop and evaluate a scientific information exchange model at digital library on Internet of things. In order to attain the objective, the model's components are extracted first. This study is a developmental study using mixed method consisting of documentary, focus group, data modeling, and quantitative evaluation methods. The study population in the documentary section includes the study of information resources retrieved in related subjects. The study population in the focus group section consists of 9 experts in “Internet of things” and “digital library”. Data gathering procedure was done by applying a checklist, and Edraw Max, Protégé, evaluation tab of Protégé software is applied for the analysis. Based on the findings of the documentary method (examining 10 core models and ontologies in the field of Internet of Things, physical and virtual objects), 44 key concepts, 108 sub-concepts, and 62 attributes constitute the primary core elements of scientific information exchange model at digital library in the context of internet of things. The findings showed that the 9 main classes, namely “end-user”, “librarian”, “microcomputer”, “digital library server”, “automated information services”, “physical resources”, “virtual resources”, “information resources on the digital library server”, and “security” in general model of scientific information exchange are very contributive. In general, 27 sub-classes and 38 attributes are identified for the main classes for this purpose. In this model, the way the classes communicate and interact with one another is illustrated to justify this theme. The evaluation of the model showed that the hierarchical structure of the concepts is not dense and some types of property and property restriction have not been considered. To make use of Internet of Things in libraries, the modeling of all the essential elements and properties of the internet of things in libraries must be incorporated into a model that constitutes the logical structure of the digital library scientific information exchange database system. This model can serve as a database map for database professionals and designers. © 2021 Iranian Research Institute for Scientific Information and Documentation. All rights reserved.

In this paper, the opinions of bioinformatics experts were sought to examine the knowledge semantic maps. The research question was whether the mapping of bioinformatics field articles could contribute to the reflection of knowledge map in this field; can knowledge within articles be demonstrated through a knowledge map? The research type was applied and analytical. Data collection was performed in two ways. First, the data were collected from scientific databases by using semantic search software and drawing knowledge maps by the software. Second, Delphi technique was used in two stages in order to obtain the opinion of experts regarding these knowledge semantic maps and co-concepts in bioinformatics field. In this method, first, the co-concepts map of the articles exported by Yewno and the knowledge semantics map were presented to the experts to get their viewpoints. By implementing the Delphi approach, the opinions of experts in examining the application of knowledge semantic maps resulted in the phonological analysis of articles in this field. The analysis results demonstrated that the knowledge map of bioinformatics studies dynamically developed over time. The continuous conduction flow of scientific studies in this field brought continuous changes to the knowledge of this field. © 2020. All Rights Reserved.

With the proliferation of the Internet and the rapid growth of electronic articles, text classification has become one of the key and important tools for data organization and management. In text classification a set of basic knowledge is provided to the system by learning. Then, new input documents enter to one of the subject groups. In health literature due to wide variety of topics, preparing such a set of early education is a very time consuming and costly task. The purpose of this article is to present a hybrid model of learning (supervised and unsupervised) for the subject classification of health scientific products that performs the classification operation without the need for an initial labeled set. To extract the thematic model of health science texts from 2009 to 2019 at PubMed database, data mining and text mining were performed using machine learning. Based on Latent Dirichlet Allocation model, the data were analyzed and then the Support Vector Machine was used to classify the texts. In the findings of this study, the model was introduced in three main steps. In data preprocessing, the unnecessary words were eliminated from the data set and the accuracy of the proposed model increased. In the second step, the themes in the texts were extracted using the Latent Dirichlet Allocation method, and as a basic training set in step 3, the data were backed up by the Support Vector Machine algorithm and the classifier learning was performed with the help of these topics. Finally, with the help of the classification, the subject of each document was identified. The results showed that the proposed model can build a better classification by combining unsupervised clustering properties and prior knowledge of the samples. Clustering on labeled samples with a specific similarity criterion merges related texts with prior knowledge, and the learning algorithm teaches classification by supervisory method. Combining classification and clustering can increase the accuracy of classification of health texts. © 2020 Iranian Research Institute for Scientific Information and Documentation.

The purpose of this study is identifying the influential factors in creating query suggestions. The query suggestion has become one of the most fundamental features of web search engines that help user formulate the query and meet the information needs by providing possible keywords. In this research, in order to identify the effective factors in creating the query suggestions a systematic review has been used. For this purpose, keywords of English and Persian language related to query suggestions have been searched in foreign scientific databases such as Science Direct, Emerald, Scopus, Online Willy, IEEE and internal databases of Magiran, Scientific Information Database of Jihad, and Cilivica to find articles related with the effective contextual factors in creating query suggestions. In order to systematic review, the method of Wright et al. was used that include seven steps: determination of research question, determination of protocol, literature search, data extraction, quality appraisal, data analysis and result. After searching for Persian and English keywords and matching them with entry and exit criteria, 36 articles were selected to extract effective factors. The findings of the systematic review in the field of the query suggestion show that five factors of location, time, user search sessions (including the user’s current search session and user search history), hybrid factors, and other contexts were effective in creating query suggestions. Identification of the influential factors in creating query suggestions helps researchers and those who are interested in this domain to use appropriate contexts in accordance with the characteristics and conditions of the search tools and help the user to retrieve more relevant information. © 2019 Iranian Research Institute for Scientific Information and Documentation.

Purpose: Query suggestions are contributive in formulating queries and improving search results on the Web. This tool is used in most search and retrieval systems like the search engines, databases, personal search tools and so on. The factors affecting the use of query suggestions by the users from the perspective of experts are identified. Methodology: First, a number of factors are identified through the documentary methodology, and next the significance of each factor is determined through the fuzzy Delphi method here Findings: A total of 48 factor is extracted from the available literature view and is classified into 13 categories of demographic characteristics, search experience, domain knowledge and expertise, linguistic features, user's query, creativity creation, psychological and cognitional, source of creation of query suggestions, contextual factors, semantic features of query suggestions, structural characteristics of query suggestions, increasing the user's performance and ease of use. To assess the importance of these factors eight factors are eliminated and 40 factors are identified as the final factors affecting the use of query suggestions through Fuzzy Delphi method. Research limitations/implications:The results of this research can be used to present a structuralinterpretation model in which the most important factor is identified through the view of the experts. Originality/Value: The results obtained in this study will assist researchers and designers of search tools to apply the knowledge gained from effective factors in providing algorithms for query suggestions in their search tools. The factors extracted in this study are fundamental and basic which researchers can use when examining the performance and status of the query suggestion of each search tool. © 2019 Library Philosophy and Practice.

The purpose of this conceptual research was to explain the capabilities, semantic platform and view point of Schema.org to processing and organization of web content objects (data entities) by analytical approach. To collect data documentary analysis was used. The research community included texts and researches related to the field of "structured data" and "Schema.org". A total of 43 sources, as well as the official website of the "Schema.org" were selected using a purposive sampling method for analysis. The results of the survey showed that Schema.org is a common vocabulary that is used to describe and markup web content objects and create structured data for better processing and organization. It has a certain structure and semantic platform. Its structure is like an ontology for naming the types and properties of content objects, the relationships between types and properties, and the capabilities of describing these properties and relationships. Its semantic platform is adapted by semantic markups such as microformat, microdata, RDFa 1.1, and JSON-LD. The results of the research showed that there are three major approaches to the processing and organizing of content objects in the Schema.org: The ontological, context-oriented, and nesting approaches. Overall research results showed existence of different approaches to Schema. org represents a comprehensive view of the Web content objects while paying attention to improving interoperability with search engines. Also, the production of structured data with such schemata is an important contribution to the realization of semantic web or web of data. © 2019 Iranian Research Institute for Scientific Information and Documentation.

Introduction: This paper aims to develop a Scientific Information Exchange General Model at Digital Library in Context of Internet of things, which would enable automated and efficient library services. To accomplish its objective, the main classes (Concepts), sub-classes, attributes are identified in order to introduce an appropriate model. Methodology: The approach of this study is basic, exploratory, and developmental and is run through a mixed method consisting of documentary, Delphi, and data modeling methods. The study population in the documentary section includes the study of information resources retrieved in related subjects. The study population in the Delphi section is consist of 15 experts in "Internet of Things" and "digital library" domains. The Data gathering procedure is by applying a semi-structured interview. Appropriate software is applied for the analysis. Results: The findings showed that the 9 main classes of "End user", "librarian", "Microcomputer", "Digital library server", "Automated information services", "Physical resources", "Virtual resources", "Information resources on the digital library server (virtual object)", and "Security" in general model of scientific information exchange are very contributive. In general, 27 sub-classes and 38 attributes are identified for the main classes for this purpose. In this model, how the classes communicate and interact with one another is illustrated to justify this theme. Conclusion: Here it is deduced that focusing on data protection at two levels of user and server in the main class of security is very important. Focusing on information resources metadata in the entity class, and device to device communication in this model is of essence as well. This proposed model is contributive in information networking in Internet of things-based library systems in providing better services to users. Research value: This model has potential in offering a basic proposal as a startup for automated library services. © 2019 Library Philosophy and Practice.

Ontology is a useful tool for organizing resources and on the other hand is a useful tool for the knowledge representation. With the development of semantic web technologies, building and creating ontologies to expedite the process is necessary. The aim of the study is to explain the situation of methodologies, designing scientometrics conceptual model, and steps of ontology construction as ScientometricsOnt. The method of the study is applied research. The research population of the study is book, article, glossary, thesaurus, dissertation, and research projects of the field of scientometrics in Persian language. To collect terms internal databases are used and related resources are searched. For creating scientometrics conceptual model and explaining relationships and individuals domain analysis approach is used. The reliability and validity of scientometrics conceptual model have been approved by experts in the field of scientometrics. The tool for building ontology is Protégé 5 software. The used methodology was OAsys method Bermejo (2007) with some changes. The results revealed that Ontology of scientometrics was formed in eleven major class which has 20 relationships and 100 individuals. This ontology can be a very useful tool for better knowledge representation in this field. Also, Scientometrics ontology can be a basis for extending and developing terms and future concepts in the field. © 2018 Iranian Research Institute for Scientific Information and Documentation.

Based on Eysenbach's view, infodemiology can be defined as the science of distribution and determinants of information in an electronic medium, specifically the Internet, or in a population, with the ultimate aim to inform public health and public policy. The current study aimed to investigate the state of health information supply and demand on stomach cancer among Iranian medical researchers and Iranian web users during 2011 to 2015. A mixed method research was conducted in this study. In qualitative part, a focus group interview was applied to the users to identify their selected keywords searched for stomach cancer on Google. The collected data were analyzed using Open Code software. In quantitative part, data were synthesized using R software in two parts. First, users' Internet information seeking behavior (ISB) was analyzed using Google Trends outputs during 2011 to 2015. Second, the scientific publication behavior (SPB) of Iranian stomach cancer specialists was surveyed using PubMed during the period of the study. Eight keywords extracted by focus group interview were entered in the "Google Trends" main page. The results showed that the search volume index of preferred keywords on stomach cancer have increased from 475 in 2011 to 879 in 2015. Also, the findings revealed that Iranian scholars had 194 scientific papers on stomach cancer in PubMed during 2011 to 2015. There was a significant and positive relationship between Iranian ISB in the Google Trends and SPB of Iranian scholars on stomach cancer in PubMed. From infodemiological viewpoint, it has been elucidated that the alignment of ISB and SPB in medical studies can illustrate the purposefulness of these investigations. © 2017, Shohreh SeyyedHosseini, Asefeh Asemi, Ahmad Shabani and Mozafar CheshmehSohrabi.

The purpose of this study was to identify the most important historical works written in the field of commercialization of knowledge using Referenced Publication Years Spectroscopy (RPYS). Initial data were obtained from the Web of Science (WoS) database to investigate the historical roots of published works in the field of commercialization of knowledge. Then, the main roots of this filed, the amount of received citations, and influential works were identified using RPYS software. Next, with the help of the yearcr software, the extent of the effects of the works outside of the range of peaks were also introduced. The period under investigation is the publication in the years 1900-2015. by searching published works in the time period of 1900-2015, 1550 records related to commercialization of knowledge were retrieved. To exactly investigate the effects of this field, the timeframe was divided into five periods (four 25-year periods and one 15-year period) to allow peaks with a small number of citations in the early years. The total number of citations up to the time of the present research was 39817, which resulted in the emergence of five peaks in the years 1934, 1962, 1973, 1998, and 2003.

The present study investigated the analysis of search engines and meta search engines adoption process by University of Isfahan users during 2009-2010 based on the Rogers' diffusion of innovation theory. The main aim of the research was to study the rate of adoption and recognizing the potentials and effective tools in search engines and meta search engines adoption among University of Isfahan users. The research method was descriptive survey study. The cases of the study were all of the post graduate students of the University of Isfahan. 351 students were selected as the sample and categorized by a stratified random sampling method. Questionnaire was used for collecting data. The collected data was analyzed using SPSS 16 in both descriptive and analytic statistic. For descriptive statistic frequency, percentage and mean were used, while for analytic statistic t-test and Kruskal-Wallis non parametric test (H-test) were used. The finding of t-test and Kruscal-Wallis indicated that the mean of search engines and meta search engines adoption did not show statistical differences gender, level of education and the faculty. Special search engines adoption process was different in terms of gender but not in terms of the level of education and the faculty. Other results of the research indicated that among general search engines, Google had the most adoption rate. In addition, among the special search engines, Google Scholar and among the meta search engines Mamma had the most adopting rate. Findings also showed that friends played an important role on how students adopted general search engines while professors had important role on how students adopted special search engines and meta search engines. Moreover, results showed that the place where students got the most acquaintance with search engines and meta search engines was in the university. The finding showed that the curve of adoption rate was not normal and it was not also in S-shape. Morover, among simple and advanced pages of Google, a specific bias toward simple search pages could be seen in users. This part of the study confirmed Rogers' theory. Other results of the study indicated that renouncement of innovation was not only in decision phase. This part of the investigation was in conflict with Rogers' theory.
