Introduction: In emerging figures, scholars are unifying social media tools like blogs, Twitter, and Mendeley into their professional communications. The online, open nature of these tools reveals the scholarly action to be clear and unambiguous. Metrics which is set on these activities could enlighten broader, faster measures of impact, supplementing traditional citation metrics. Aim:The present review aims to analyse the correlation of altmetrics with the traditional citations in medical research. Materials and Methods:The search strategy used a combination of controlled vocabulary and free text terms. The main database searched were PubMed, PubMed Central, Cochrane Review, Embase and Google Scholar from 2010 to 2016. Out of the total 78 titles appeared seven articles fulfilled the criteria and were selected for the review. Results:The positive correlation between altmetrics and traditional citations indicates that the two are not entirely different from each other and are familiar with each other. Altmetrics are usually accessible earlier and enable us to evaluate the social impact of scholarly research, almost at the actual time. Conclusion:Much work is needed to develop this research which will focus on the clarity of the impact signal. Thus newer dimensions, such as altmetrics and article-level metrics are an effort to explore the influence of research across the worldwide population.

Purpose This study aims to explore linked data (LD) initiatives in libraries and information (LI) centres along with motivating factors to start these LD projects and challenges faced by librarians in implementing LD technology. Design/methodology/approach To achieve the objectives of the study, a systematic literature review was conducted. The preferred reporting items were used for systematic review and meta-analysis (PRISMA) guideline. Data were collected from different scholarly databases. Findings Findings show that many initiatives were taken in LI centres during the past decade. These LI centres had to face many challenges to implement LD technology. These challenges might include technological issues, scarce financial resources, lack of skilled human resources, low level of awareness among community/librarians, proprietary licence, non-availability of standards and best practices. However, technological challenges were more complex. Systematic review shows that most of the LD initiatives and activities in LI centres take place in developed countries. Overall, the results reveal that most of the libraries are in the infancy stage of LD application because of the ambivalent nature of technology. Originality/value This study may be beneficial to devise guidelines to transform the aforementioned different challenges into opportunities. It is also important to provide a holistic picture about the challenges and opportunities of LD through a systematic review of initiatives already taken by LI centres.

PurposeThe purpose of this study is to explore the relationship between mobile self-efficacy and personal information management (PIM) practices through mobile phones and smartphones, and additionally, to explore the challenges of using a smart device for PIM.Design/methodology/approachThis study followed Preferred Reporting Items for the Systematic Review and Meta-analysis (PRISMA) guidelines to achieve the objectives. A comprehensive search strategy, inclusion criteria and exclusion criteria were formulated in light of PRISMA guidelines. The data were collected from different scholarly repositories, databases and core journals of PIM. The studies were included after four steps, i.e. identification, screening, eligibility and inclusion of studies.FindingsFindings revealed that there was a positive relationship between mobile self-efficacy and PIM via mobile phones. People used two techniques for finding and re-finding information via mobile phones/smartphones. These techniques include browsing and searching information. People send information, share with others and save in draft folders to emails in mobile phones/smartphones for keeping information for future use. They organize their personal information in folders and use different applications such as Evernote, Google Calendar, alarm and organizer. They uninstall and update mobile applications with new versions, clear phone call history and backup personal information to desktop devices and cloud services to maintain personal information. PIM via mobile phone/smartphone challenges were also identified. These challenges were classified as information related challenges, technical challenges, mobile phone adaptability challenges and miscellaneous challenges.Originality/valueThis study will help library professionals and decision makers to devise information literacy instruction programs according to the users' needs. The results of this study will also open new horizons for system designers to devise mobile-based PIM tools according to users' needs.
