Comparing the Scientific Impact of Conference and Journal Publications in Computer Science
Proc. Academic Publishing in Europe (APE08) 2008
The impact of scientific publications is often estimated by the number of citations they receive, i.e. how frequently they are referenced by other publications. Since publications have associated authors, originating institutions and publication venues (e.g. journals, conference proceedings) citations have also been used to compare their scientific impact. For instance, one commonly considered indicator of the quality of a journal is its impact factor [AM00]. The impact factors are published yearly by Thomson ISI in the Journal Citation Report (JCR) by counting the citations from articles of thousands of journals. However, research results in computer science are often published in high-quality conferences which are not covered by the JCR citation databases [MV07]. Other commercial citation data sources such as Elsevier Scopus also focus on journals and contain comparatively few conference publications. Hence these data sources cover only a fraction of quality scientific publications in computer science. Furthermore, they miss many citations even for journal articles since all references to them are not captured which originate from conference papers or other papers not included in the publication database.
