Abstract
Purpose
This paper evaluates the precision of four metasearch engines (MSEs) – DuckDuckGo, Dogpile, Metacrawler and Startpage, to determine which metasearch engine exhibits the highest level of precision and to identify the metasearch engine that is most likely to return the most relevant search results.
Design/methodology/approach
The research is divided into two parts: the first phase involves four queries categorized into two segments (4-Q-2-S), while the second phase includes six queries divided into three segments (6-Q-3-S). These queries vary in complexity, falling into three types: simple, phrase and complex. The precision, average precision and the presence of duplicates across all the evaluated metasearch engines are determined.
Findings
The study clearly demonstrated that Startpage returned the most relevant results and achieved the highest precision (0.98) among the four MSEs. Conversely, DuckDuckGo exhibited consistent performance across both phases of the study.
Research limitations/implications
The study only evaluated four metasearch engines, which may not be representative of all available metasearch engines. Additionally, a limited number of queries were used, which may not be sufficient to generalize the findings to all types of queries.
Practical implications
The findings of this study can be valuable for accreditation agencies in managing duplicates, improving their search capabilities and obtaining more relevant and precise results. These findings can also assist users in selecting the best metasearch engine based on precision rather than interface.
Originality/value
The study is the first of its kind which evaluates the four metasearch engines. No similar study has been conducted in the past to measure the performance of metasearch engines.

This paper aims to analyze open access (OA) scholarly publishing patterns as well as OA policies and mandates across European countries.
Abstract
Purpose
This paper aims to analyze open access (OA) scholarly publishing patterns as well as OA policies and mandates across European countries.
Design/methodology/approach
The study is based on a descriptive research approach using data from Web resources, directories and bibliographic and citation databases, namely, DOAJ, OpenDOAR, SCImago journal and Country Ranking portal, ROARMAP and Web of Science.
Findings
The findings indicate that the initiatives and measures in Europe that promote OA are adequate. OA journals and digital repositories have progressively increased over the past two decades. Of the total journals (n = 25,231) published worldwide and indexed in Scopus, 53% are published in European countries, with 23.7% being OA journals. In total, 34% of the OA repositories (n = 5,714) are in European countries. The proportion of OA journal papers has grown significantly in all European countries, with a 14.3% annual growth rate. The average proportion of OA publications in European countries is significantly higher (39.07%) than the world average (30.16%), with a clear inclination for making research literature openly accessible via the green OA route (79.41%) compared to the gold OA route (52.30%). Most European research funders and institutions have required researchers to make OA available for their research findings, either by publishing them in OA journals or depositing accepted manuscripts in repositories.
Research limitations/implications
The study analyzed OA trends in Europe; other continents and countries were not included in the analysis. The study only described OA policies and mandates; the extent to which the OA policies and mandates were implemented was not studied. However, the results of the study may be helpful to policymakers, funders, research institutions and universities in other countries in adopting and implementing OA policies and mandates.
Originality/value
To the best of the authors’ knowledge, the study is the first that used multiple data sources for investigating different facets of OA publishing in European countries, including OA journals, digital repositories, research output, mandates and policies for publicly funded research. The findings will be helpful for researchers and policymakers interested in promoting OA adoption among researchers worldwide.

Abstract
Purpose
This study aims to analyze Open Access (OA) publishing trends and policy perspectives in India. Different aspects, such as the growth of OA journals digital repositories, the proportion of OA availability to research literature and the status of OA mandates and policies are studied.
Design/methodology/approach
Data for analyzing OA trends were gathered from multiple data sources, including Directory of Open Access Journals (DOAJ), OpenDOAR, SCImago and Web of Science (WoS) databases. DOAJ and OpenDOAR were used for extracting OA journals and digital repository data. SCImago Journal and Country ranking portal and WoS database were used to obtain Indian publication data for assessing the proportion of OA to research literature. ROARMAP was used to study OA mandates and policies adopted by universities, research institutions and research funders in India. OA mandates and policies of major regulatory bodies and funding agencies were also reviewed using secondary sources of information and related websites.
Findings
India ranks number 15 and 17 globally for OA journals and OA repositories, with 317 journals and 98 repositories. Although India’s proportion to OA publications is 23% (7% below the world average of 30%), the annual growth rate of OA publications is around 18%. Although the governing bodies and institutions have made efforts to mandate researchers to adopt OA publishing and self-archiving, its implementation is quite low among Indian researchers, as only three institutions (out of 18 listed in the ROARMAP) are defined the embargo period. Funding agencies in India do not provide financial assistance to authors for the payment of Article Processing Charges despite mandates that research is deposited in OA repositories. India lacks a national OA policy but plans to implement a “one nation one subscription” formula to provide OA to scientific literature to all its citizens.
Research limitations/implications
The study has certain limitations. Because much of India’s research output is published in local journals that are not indexed in WoS, the study recommends conducting further analyses of publications using Scopus and other databases to understand the country’s OA publishing proportion better. A further study based on feedback from different stakeholders through a survey may be conducted for formulating a national OA policy.
Originality/value
The study is the first that used multiple data sources for investigating different facets of OA publishing in India, including OA journals, digital repositories, OA research output and OA mandates and policies for publicly funded research. The findings will be helpful for researchers and policymakers interested in promoting OA adoption among researchers worldwide.

Abstract
Purpose
Artificial Intelligence (AI) is an emerging technology and turned into a field of knowledge that has been consistently displacing technologies for a change in human life. It is applied in all spheres of life as reflected in the review of the literature section here. As applicable in the field of libraries too, this study scientifically mapped the papers on AAIL and analyze its growth, collaboration network, trending topics, or research hot spots to highlight the challenges and opportunities in adopting AI-based advancements in library systems and processes.
Design/methodology/approach
The study was developed with a bibliometric approach, considering a decade, 2012 to 2021 for data extraction from a premier database, Scopus. The steps followed are (1) identification, selection of keywords, and forming the search strategy with the approval of a panel of computer scientists and librarians and (2) design and development of a perfect algorithm to verify these selected keywords in title-abstract-keywords of Scopus (3) Performing data processing in some state-of-the-art bibliometric visualization tools, Biblioshiny R and VOSviewer (4) discussing the findings for practical implications of the study and limitations.
Findings
As evident from several papers, not much research has been conducted on AI applications in libraries in comparison to topics like AI applications in cancer, health, medicine, education, and agriculture. As per the Price law, the growth pattern is exponential. The total number of papers relevant to the subject is 1462 (single and multi-authored) contributed by 5400 authors with 0.271 documents per author and around 4 authors per document. Papers occurred mostly in open-access journals. The productive journal is the Journal of Chemical Information and Modelling (NP = 63) while the highly consistent and impactful is the Journal of Machine Learning Research (z-index=63.58 and CPP = 56.17). In the case of authors, J Chen (z-index=28.86 and CPP = 43.75) is the most consistent and impactful author. At the country level, the USA has recorded the highest number of papers positioned at the center of the co-authorship network but at the institutional level, China takes the 1st position. The trending topics of research are machine learning, large dataset, deep learning, high-level languages, etc. The present information system has a high potential to improve if integrated with AI technologies.
Practical implications
The number of scientific papers has increased over time. The evolution of themes like machine learning implicates AI as a broad field of knowledge that converges with other disciplines. The themes like large datasets imply that AI may be applied to analyze and interpret these data and support decision-making in public sector enterprises. Theme named high-level language emerged as a research hotspot which indicated that extensive research has been going on in this area to improve computer systems for facilitating the processing of data with high momentum. These implications are of high strategic worth for policymakers, library stakeholders, researchers and the government as a whole for decision-making.
Originality/value
The analysis of collaboration, prolific authors/journals using consistency factor and CPP, testing the relationship between consistency (z-index) and impact (h-index), using state-of-the-art network visualization and cluster analysis techniques make this study novel and differentiates it from the traditional bibliometric analysis. To the best of the author's knowledge, this work is the first attempt to comprehend the research streams and provide a holistic view of research on the application of AI in libraries. The insights obtained from this analysis are instrumental for both academics and practitioners.

Abstract
Purpose
This study aims to determine the barriers hindering the incorporation of blockchain technology (BCT) in two key service industries – hotel and health care – as well as to assess their readiness for implementing BCT after overcoming the barriers.
Design/methodology/approach
The barriers of this study are determined through two phases: a review of prior literature and obtaining expert opinions, which are then analyzed to identify specific barriers that are impeding the incorporation of BCT. Moreover, to generate a blockchain implementation reluctance index (BIRI), this study presents an interval-valued intuitionistic fuzzy set (IVIFS) that uses graph theory and matrix approach (GTMA). The permanent function in the GTMA approach is computed using the PERMAN algorithm. Finally, to compare the readiness of the hotel and health-care industries to adopt BCT, the BIRI values are plotted and evaluated.
Findings
The barriers identified by this study are listed under five major headings, namely, financial, operational, behavioral, technical and legal. This study revealed that the operational and technical barriers of BCT are critically hindering its widespread integration in hotel and health-care industries. Furthermore, on comparing the BIRI values of both industries, the result suggested that the hotel industry needs to work more on these barriers to effectively incorporate BCT. Besides the comparison, the BIRI values clearly indicate that both industries have to put a lot of effort into the mitigation of the barriers found by this study to successfully integrate BCT.
Research limitations/implications
The experts’ opinions are used to evaluate the identified barriers, which raises the chance that the opinions are prejudiced based on the experts’ perspectives and ideologies. The sensitivity of decision-maker loads toward preference outcomes is not analyzed in this manuscript. Therefore, any recent sensitivity analysis may be considered a prospective field for future research. This study applies a multicriteria decision-making (MCDM) approach, IVIFS–GTMA, which limits the evaluation of the influence caused by individual barriers on the integration of BCT in the hotel and health-care industries. Henceforth, in future investigations, alternative MCDM methods may be used to analyze individual barriers.
Practical implications
According to the findings, if the hotel or health-care industry aims to incorporate BCT in its supply chain operations, it is recommended to emphasize more on the operational barriers along with the technical and behavioral barriers. The barriers mentioned in this manuscript can be used as guidance for developers in their development activities, such as scalability concerns, establishment costs, the 51% attack and the inefficient nature of BCT. Furthermore, they may address the potential users’ negative perceptions about security, privacy, trust and risk avoidance through creatively developed blockchain solutions to promote BCT implementation.
Originality/value
To the best of the author’s knowledge, this is the first study that identifies barriers toward BCT incorporation in the major service industries, i.e. hotel and health care. Moreover, this is the first study that compares the preparedness of the hotel and health-care industries to determine the industry that requires more work to implement BCT.
