OAI8: An overview of scholarly impact metrics; But: Why measure it at all in cases where the scholarly community truly has decision-making power, autonomy?

See on Scoop.itDual impact of research; towards the impactelligent university

ContentThe interest in developing scholarly impact metrics is frequently justified by the need to objectively prioritize scarce resources and to better manage scholarly productivity. However, the study of scholarly communication in general, including scholarly impact metrics, has significant relevance to a number of other scientific domains such as computational social science, social network analysis, web science, and complex systems. In this presentation I will provide an overview of established scholarly impact metrics, grounding each in their respective scientific traditions and backgrounds. Changes in scholarly communication patterns, including the move to online environments and the increasing use of social media, have recently prompted a Cambrian explosion of new impact metrics derived from new data sources. These metrics may reflect previously unexplored facets of scholarly communication and impact, and may thus yield a more complete picture of scholarly communication. In my presentation I will provide an overview of these new metrics, and identify the opportunities as well as challenges that they present. 3 innovations: A: Citation based social metrics:

Degree; In-degree/Out-degree

Random walk; PageRank/Eigenvector

Shortest path; Closeness/Betweenness

B: Behavioural: 

Scholarly community and communication is moving online.

Data pertaining to online activities (implicit, behavioral) vs. citation data (explicit declaration of influence)

C: AltMetrics:  Behavioral AND “attention” data

Social media attention, bookmarking, mentions. Attempt to also capture “social” attention or public impact of scholarly work  Source:Metrics Session: An overview of scholarly impact metricsPresented by Mr. Johan BOLLEN on 19 Jun 2013 from 15:30 to 16:00Session: Plenary 2 PDF: http://indico.cern.ch/getFile.py/access?contribId=3&sessionId=4&resId=1&materialId=slides&confId=211600PPT: http://indico.cern.ch/getFile.py/access?contribId=3&sessionId=4&resId=0&materialId=slides&confId=211600 ;
