Comparing the Scientific Impact of Conference and Journal Publications in Computer Science

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.
