Research Impact Metrics: Article-Level Metrics
This is an introduction to different research impact metrics and tools for author disambiguation.
Researchers have gradually become concerned about the appropriateness of journal-level metrics for research assessment. After meeting in Dec. 2012, a group of journal publishers and editors have released the San Francisco Declaration on Research Assessment (DORA) to highlight the need to improve how research impact is evaluated. In sum, they point out:
the need to eliminate the use of journal-based metrics, such as Journal Impact Factors, in funding, appointment, and promotion considerations;
the need to assess research on its own merits rather than on the basis of the journal in which the research is published; and
the need to capitalize on the opportunities provided by online publication (such as relaxing unnecessary limits on the number of words, figures, and references in articles, and exploring new indicators of significance and impact).
Researchers increasingly recognize the significance of assessing research at the article level with both traditional and novel data points. The SPARC Primer on article-level metrics (ALMs) notes that ALMs:
pull from distinct data streams to gauge the "scholarly visibility" and the "social visibility" of research results.
incorporate both shorter- and longer-term data points in the analysis to present a fuller picture of an article's impact over time.
can complement traditional metrics because they are more granular and more immediate.
are not proprietary products and thus research communities can develop, distribute, and build upon ALM tools in a manner that unlocks impact metrics.
However, just like other metrics, ALMs can be gamed and cannot evaluate the quality and intent of the comments on an article.
