today’s lineup… How do we measure impact in different contexts/fields? How do we rank people and things? How do we determine expertise? How do we traditionally look at “impact” in science and academic realms? (bibliometrics and citation analysis) Are traditional methods of measuring impact changing? If so, how? Evaluating information sources

how do we rank things & people?

what is citation analysis? utilizes quantitative analysis and statistics to describe patterns of publication within a given field or body of literature

what do you do with citation analysis? researchers may use bibliometric methods of evaluation to determine the influence of a single writer, for example, or to describe the relationship between two or more writers or works – production and productivity – impact – co-publication patterns – connections between subject areas

Scholarly communication process Traditional example

Scholarly communication process What’s captured traditionally

How is scholarly communication changing? Think of scholarly communication as continuous process instead of single product (journal publication). Capture significant changes/versions of a work. Include all criticisms and comments about work (all stages). Support normal scholarly discourse, including authors responses as well as others’ comments. Add reviewer’s quantitative rating of material to allow better filtering based on absolute quality metric during retrieval. Add machine (automated) reviews. Include other forms of information (audio, pictures, video, graphs, datasets, statistics)

Now scholars have the ability to share their research data in repositories on the Web. Information is expanding by orders of magnitude; ideas are being formulated through open-access blogs and social media sites such as Twitter. Editors [expert peer-reviewers] are no longer employed as proxy community assessors but are now represented by collective judgments of communities on the Web itself. -Benny

Provocative Questions for Discussion What/why do you (and scholars cite? What do you infer from a reference list? Are all citations equal?

points to take away Cite sources you use – Supports your case/research – Avoid plagiarism – Places your work within scholarly dialogue Use reference lists to find additional/relevant material Look for material that cites your source – will be more recent Web of Science can also be used as a regular lit database
