Poster (and extended abstract) presented at the 13th International Conference "Libraries in the Digital Age (LIDA 2014)" held on 16-20th June, University of Zadar, Zadar, Croatia; The aim of this project is to find out if and how Institutional Repositories (IR) are using alternative metrics or Altmetrics (besides usage statistics and citation counts) as a value-added service to showcase their content impact and give some hints on how this tool can be used to supplement the traditional research performance assessment exercise in an institution. Altmetrics can provide a measure of impact for all non-journal scholarly works available in Open Access (OA), like usage statistics, but it can go further by contextualizing the readership of an author’s research output. The increasing importance of Altmetrics indicators led to its inclusion in the 2014 edition of the Ranking Web of Repositories. This project promises to be useful for repositories managers in that it gives some examples of good practices of implementation of Altmetrics along with other metrics in IRs which can help to increase the content, foster the adoption of OA by authors, contribute to the visibility of the institution and meet the funding agencies requirements, thus making a strong case for the relevance of IRs in the context of the research assessment process.

Altmetric measurements derived from the social web are increasingly advocated and used as early indicators of article impact and usefulness. Nevertheless, there is a lack of systematic scientific evidence that altmetrics are valid proxies of either impact or utility although a few case studies have reported medium correlations between specific altmetrics and citation rates for individual journals or fields. To fill this gap, this study compares 11 altmetrics with Web of Science citations for 76 to 208,739 PubMed articles with at least one altmetric mention in each case and up to 1,891 journals per metric. It also introduces a simple sign test to overcome biases caused by different citation and usage windows. Statistically significant associations were found between higher metric scores and higher citations for articles with positive altmetric scores in all cases with sufficient evidence (Twitter, Facebook wall posts, research highlights, blogs, mainstream media and forums) except perhaps for Google+ posts. Evidence was insufficient for LinkedIn, Pinterest, question and answer sites, and Reddit, and no conclusions should be drawn about articles with zero altmetric scores or the strength of any correlation between altmetrics and citations. Nevertheless...

The number of academic articles published annually has risen exponentially in the past decade, making our jobs as librarians ever more challenging as we assist patrons in finding exactly what it is that they are looking for. At the same time, traditional measures of research quality such as the journal impact factor and citation counts have been called into question for being unreliable and slow to accumulate. Though these measures have helped librarians filter for quality content in the past, they show weakness when applied to the rapidly evolving scholarly publication marketplace. Neither can be easily applied to non-traditional scholarly outputs such as working papers, technical reports, data sets, or conference presentations. We have also recently seen a rise in Open Access (OA) publications, which make research easier to access than ever before. Megajournals such as PLOS ONE and Sage Open publish more articles in a day than some journals do in a year. The sheer volume of available scholarship is enough to make one???s head spin. Given these challenges, how can librarians help patrons access what they seek while at the same time make our own jobs easier as we sift through the ever-rising sands of available scholarship? Enter altmetrics...

In this talk, Cassidy Sugimoto argues that altmetrics have failed to deliver on their promise. She discusses criticisms of altmetrics (including those dealing with validity and reliability issues), but argues that the largest failure of altmetrics has been the focus on a single genre—that is, the journal article—and setting altmetrics up as an alternative to citations. Sugimoto introduces the notion of outcomes-based evaluation and demonstrates that altmetrics cannot be equated with outcomes in this model. She urges the community to rethink ways in which we can build metrics that can capture larger societal impact. She discusses four axes of potential impact: production, dissemination, engagement, assessment. In each of these, she reviews various examples of current initiatives and challenges the audience to conceive of possible metrics to capture the desired outcome in each scenario.

Se busca identificar los pasos, a modo de hoja de ruta, que deben dar los bibliotecarios en la difusión, formación y asesoramiento de las métricas complementarias o altmetrics en el marco de los servicios que ofrecen a sus investigadores. Así mismo se enumeran una serie de razones por las que los bibliotecarios deben tener un papel activo en relación a estas métricas sin olvidar sus limitaciones. Se ha realizado una revisión de la bibliografía y dirigido una encuesta online a bibliotecarios de universidades españolas para conocer su grado de implicación y actividad en este tema, contribuyendo a proporcionar la visión que tienen de las altmetrics ya que representan un elemento estratégico en su difusión y formación.; Abstract: Our aim is to identify the steps that librarians can take concerning altmetrics within the framework of the research support services. The current bibliography on altmetrics has been reviewed. 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. 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. This research offers a user guide for librarians as an orientation in their activities and initiatives related to altmetrics...

En el presente trabajo se realiza una revisi??n de las altmetrics o indicadores alternativos. Este concepto se define como la creaci??n y estudio de nuevos indicadores, basados en la web 2.0, para el an??lisis de la actividad cient??fica y acad??mica. La idea que subyace es que, por ejemplo, las menciones en blogs, el n??mero de tuits o el de personas que guardan un art??culo en su gestor de referencias puede ser una medida v??lida del uso y repercusi??n de las publicaciones cient??ficas. En este sentido, estas medidas se han situado en el centro del debate de los estudios bibliom??tricos cobrando especial relevancia. En el art??culo se ilustran en primer lugar las plataformas e indicadores principales de este tipo de medidas, para posteriormente estudiar un conjunto de trabajos del ??mbito de la comunicaci??n, comparando el n??mero de citas recibidas con sus indicadores 2.0. Los resultados se??alan que los art??culos m??s citados de la disciplina en los ??ltimos a??os tambi??n presentan indicadores significativamente m??s elevados de altmetrics. Seguidamente se realiza un repaso por los principales estudios emp??ricos realizados, deteni??ndonos en las correlaciones entre indicadores bibliom??tricos y alternativos.

En 2012 se multiplicaron las propuestas sobre nuevos indicadores asociados a aplicaciones de la web social, denominados altmetrics (o m??tricas alternativas) y se presentan como una alternativa a la evaluaci??n de la actividad cient??fica. Sin embargo, pese a las m??ltiples propuestas, dicho campo a??n est?? en fase embrionaria. Se presentan algunas posibles limitaciones de los nuevos indicadores: 1) gran n??mero de fuentes de informaci??n e indicadores que hacen dif??cil establecer su clasificaci??n y relevancia; 2) muchos no tienen demasiada validez estad??stica por los pobres resultados que generan; 3) es dif??cil determinar cu??l es el significado de las nuevas medidas ya que no sabemos si se mide exactamente impacto social o cient??fico; y 4) car??cter evanescente y ef??mero.; In 2012 there were many proposals for new indicators associated with social web tools. These indicators have been termed as altmetrics (or alternative metrics) and are presented as an alternative to the evaluation of scientific activity. In this paper some possible limitations of the new indicators are presented. More specifically these shortcomings are: 1) a large number of information sources and indicators that make it difficult to establish their classification and relevance; 2) some indicators that have no statistical validity because they generate poor results; 3) the difficulty of determining the meaning of the new metrics ???what are we assessing...

Publicada como Nota ThinkEPI; En septiembre de 2015, Web of Science, incorpor?? por primera vez en su historia a su base de datos indicadores no puramente bibliom??tricos. El nuevo indicador, denominado usage counts o ???conteo de uso???, mide el n??mero de veces que se accedi?? al texto completo de un documento o que un registro se export?? a un gestor bibliogr??fico. Se ofrece el mismo indicador con dos ventanas temporales diferentes: uno que mide los clics en los ??ltimos 180 d??as y otro desde 2013. Para descifrar el significado del nuevo indicador, aparte de reflexionar sobre la naturaleza de los actos que se pretenden medir, se realiza un estudio exploratorio donde estos nuevos indicadores de uso son comparados con los tradicionales conteos de citas, seleccionando dos submuestras: una con los documentos m??s altamente citados de 2015 (hasta la fecha), y otra con los m??s usados. Las grandes diferencias encontradas entre las dos submuestras parecen indicar que estos dos indicadores miden diferentes tipos de impacto. Y es que, la citaci??n y el uso de los documentos son acciones tan distintas, que sus recuentos deben ofrecer resultados divergentes. Es por lo que las nuevos recuentos enriquecen el set de indicadores bibliom??tricos de la Web of Science.

The IUScholarWorks Repository is a DSpace-based institutional repository for the dissemination and preservation of Indiana University's scholarly output. As in many institutional repositories, the statistics tracked for repository content have historically been concerned with a) the number and size of items held in our repository, and b) the page views and downloads for those item records (Wacha & Wisner, 2011). To date, these statistics have mostly been used for internal reference. With the rise of researcher awareness of alternative metrics (commonly called “altmetrics”) that track the usage and sharing of scholarly outputs on the social web (Priem, Taraborelli, Groth, & Neylon, 2010), the IUScholarWorks team has been interested in the idea of implementing altmetrics as a value-added service for depositors. We have partnered with Altmetric.com to test deployment of the service in two phases described below, with eventual roll-out to our production repository.

Scholars are increasingly incorporating social media tools like blogs, Twitter and Mendeley into their professional communications. Altmetrics tracks usage of these and similar tools to measure scholarly influence on the social web. Altmetrics researchers and practitioners have amassed a growing body of literature and working tools to gather and analyze altmetrics and there is growing interest in this emerging subfield of scientometrics. Panelists will present results demonstrating the utility of alternative metrics from a variety of stakeholders: researchers, librarians, publishers and those participating in academic social media sites.

This chapter discusses altmetrics (short for "alternative metrics"), an approach to uncovering previously-invisible traces of scholarly impact by observing activity in online tools and systems. I argue that citations, while useful, miss many important kinds of impacts, and that the increasing scholarly use of online tools like Mendeley, Twitter, and blogs may allow us to measure these hidden impacts. Next, I define altmetrics and discuss research on altmetric sources--both research mapping the growth of these sources, and scientometric research measuring activity on them. Following a discussion of the potential uses of altmetrics, I consider the limitations of altmetrics and recommend areas ripe for future research.; Comment: Published in Cronin, B., & Sugimoto, C. R.

The article-level metrics (ALMs) or altmetrics becomes a new trendsetter in recent times for measuring the impact of scientific publications and their social outreach to intended audiences. The popular social networks such as Facebook, Twitter, and Linkedin and social bookmarks such as Mendeley and CiteULike are nowadays widely used for communicating research to larger transnational audiences. In 2012, the San Francisco Declaration on Research Assessment got signed by the scientific and researchers communities across the world. This declaration has given preference to the ALM or altmetrics over traditional but faulty journal impact factor (JIF)-based assessment of career scientists. JIF does not consider impact or influence beyond citations count as this count reflected only through Thomson Reuters' Web of Science database. Furthermore, JIF provides indicator related to the journal, but not related to a published paper. Thus, altmetrics now becomes an alternative metrics for performance assessment of individual scientists and their contributed scholarly publications. This paper provides a glimpse of genesis of altmetrics in measuring efficacy of scholarly communications and highlights available altmetric tools and social platforms linking altmetric tools...

I propose a broad, multi-dimensional conception of altmetrics, namely as traces of the computerization of the research process. Computerization should be conceived in its broadest sense, including all recent developments in ICT and software, taking place in society as a whole. I distinguish four aspects of the research process: the collection of research data and development of research methods; scientific information processing; communication and organization; and, last but not least, research assessment. I will argue that in each aspect, computerization plays a key role, and metrics are being developed to describe this process. I propose to label the total collection of such metrics as Altmetrics. I seek to provide a theoretical foundation of altmetrics, based on notions developed by Michael Nielsen in his monograph Reinventing Discovery: The New Era of Networked Science. Altmetrics can be conceived as tools for the practical realization of the ethos of science and scholarship in a computerized or digital age.; Comment: Posted on 17 Oct 2015.

The study explores the citedness of research data, its distribution over time and how it is related to the availability of a DOI (Digital Object Identifier) in Thomson Reuters' DCI (Data Citation Index). We investigate if cited research data "impact" the (social) web, reflected by altmetrics scores, and if there is any relationship between the number of citations and the sum of altmetrics scores from various social media-platforms. Three tools are used to collect and compare altmetrics scores, i.e. PlumX, ImpactStory, and Altmetric.com. In terms of coverage, PlumX is the most helpful altmetrics tool. While research data remain mostly uncited (about 85%), there has been a growing trend in citing data sets published since 2007. Surprisingly, the percentage of the number of cited research data with a DOI in DCI has decreased in the last years. Only nine repositories account for research data with DOIs and two or more citations. The number of cited research data with altmetrics scores is even lower (4 to 9%) but shows a higher coverage of research data from the last decade. However, no correlation between the number of citations and the total number of altmetrics scores is observable. Certain data types (i.e. survey, aggregate data, and sequence data) are more often cited and receive higher altmetrics scores.; Comment: Accpeted for publication at the 15th International Conference on Scientometrics and Informetrics (ISSI 2015)

Today, it is not clear how the impact of research on other areas of society than science should be measured. While peer review and bibliometrics have become standard methods for measuring the impact of research in science, there is not yet an accepted framework within which to measure societal impact. Alternative metrics (called altmetrics to distinguish them from bibliometrics) are considered an interesting option for assessing the societal impact of research, as they offer new ways to measure (public) engagement with research output. Altmetrics is a term to describe web-based metrics for the impact of publications and other scholarly material by using data from social media platforms (e.g. Twitter or Mendeley). This overview of studies explores the potential of altmetrics for measuring societal impact. It deals with the definition and classification of altmetrics. Furthermore, their benefits and disadvantages for measuring impact are discussed.; Comment: Accepted for publication in the Journal of Informetrics

An extensive analysis of the presence of different altmetric indicators provided by Altmetric.com across scientific fields is presented, particularly focusing on their relationship with citations. Our results confirm that the presence and density of social media altmetric counts are still very low and not very frequent among scientific publications, with 15%-24% of the publications presenting some altmetric activity and concentrating in the most recent publications, although their presence is increasing over time. Publications from the social sciences, humanities and the medical and life sciences show the highest presence of altmetrics, indicating their potential value and interest for these fields. The analysis of the relationships between altmetrics and citations confirms previous claims of positive correlations but relatively weak, thus supporting the idea that altmetrics do not reflect the same concept of impact as citations. Also, altmetric counts do not always present a better filtering of highly cited publications than journal citation scores. Altmetrics scores (particularly mentions in blogs) are able to identify highly cited publications with higher levels of precision than journal citation scores (JCS), but they have a lower level of recall. The value of altmetrics as a complementary tool of citation analysis is highlighted...
