    • "Altmetrics is the research area that investigates these possibilities. While altmetrics still lacks a widely agreed definition, the concept is typically used to describe the measurement of impact or visibility of scientific articles and other scholarly activities in social media such as blogs, tweets, Facebook ‘likes’ and social bookmarks [8]. While scholars are using many different social media sites for scholarly communication, Twitter seems to be one of the most promising contexts in which to perform altmetric research because it contains more scientific content than many other social media sites [9].

    ABSTRACT: Because Twitter and other social media are increasingly used for analyses based on altmetrics, this research sought to understand what contexts, affordance use, and social activities influence the tweeting behavior of astrophysicists. Thus, the presented study has been guided by three research questions that consider the influence of astrophysicists' activities (i.e., publishing and tweeting frequency) and of their tweet construction and affordance use (i.e. use of hashtags, language, and emotions) on the conversational connections they have on Twitter. We found that astrophysicists communicate with a variety of user types (e.g. colleagues, science communicators, other researchers, and educators) and that in the ego networks of the astrophysicists clear groups consisting of users with different professional roles can be distinguished. Interestingly, the analysis of noun phrases and hashtags showed that when the astrophysicists address the different groups of very different professional composition they use very similar terminology, but that they do not talk to each other (i.e. mentioning other user names in tweets). The results also showed that in those areas of the ego networks that tweeted more the sentiment of the tweets tended to be closer to neutral, connecting frequent tweeting with information sharing activities rather than conversations or expressing opinions.

    • "tes are personal information management tools that some researchers use in their daily activities . User interactions in social bookmarking sites can provide valuable data that could be useful for research evaluation ( Neylon & Wu , 2009 ) . For example , there seems to be plentiful data about biomedicine articles in social bookmarking platforms ( Priem et al . , 2012 ) . A case study of BibSonomy revealed that the most bookmarked publication types were journal articles ( Borrego & Fry , 2012 ) . Haustein and Siebenlist ( 2011 ) used bookmarking data for 45 physics journals from CiteULike , Connotea and BibSonomy in order to evaluate the journals . There is evidence that at least some altmetrics can "

    ABSTRACT: Although there is evidence that counting the readers of an article in the social reference site, Mendeley, may help to capture its research impact, the extent to which this is true for different scientific fields is unknown. This study compares Mendeley readership counts with citations for different social sciences and humanities disciplines. The overall correlation between Mendeley readership counts and citations for the social sciences was higher than for the humanities. Low and medium correlations between Mendeley bookmarks and citation counts in all the investigated disciplines suggest that these measures reflect different aspects of research impact. Mendeley data was also used to discover patterns of information flow between scientific fields. Comparing information flows based on Mendeley bookmarking data and cross disciplinary citation analysis for the disciplines revealed substantial similarities and some differences. Thus, the evidence from this study suggests that Mendeley readership data could be used to help capture knowledge transfer across scientific disciplines, especially for people that read but do not author articles, as well as giving impact evidence at an earlier stage than is possible with citation counts.

    • "Scientific journals specialized in bibliometric subjects are the ones which have shown most interest in the matter. Among the publications most cited, the Manifesto (Priem, et al, 2012) stands out above them all. Since its publication it has been referenced in more than a hundred publications. "

    ABSTRACT: Purpose. Our aim is to identify the steps that librarians can take concerning altmetrics within the framework of the research support services offered by librarians. Design/Methodology/Approach. The current bibliography on altmetrics has been reviewed, especially that which refers to librarians. A survey has also been carried out of librarians of Spanish universities to find out their degree of involvement in the matter and the setting up of relevant initiatives. Findings. Librarians have an important role in the disseminating of altmetrics and in the training of using them in the best interests of their researchers' scientific publications. This role is also important as assessors for the administration in order to value these metrics in university processes, as well as their inclusion in catalogs, databases or repositories. Research limitations/implications. Limitations are the reduced size of the population of the surveys, especially their being limited to a single country. Likewise, a thorough study which would enable librarians to find out about the use which their researchers make of social networks and the interest that they may have in altmetrics is needed. Practical implications. This research offers a user guide for librarians as an orientation in their activities and initiatives related to altmetrics, as well as a list of arguments which justify the reasons why librarians should undertake these initiatives. Originality/Value. We contribute a view of altmetrics from the perspective of librarians as a strategic element of dissemination and training in altmetrics.
