- Field delineation is important in bibliometrics. Particularly when measuring scientific performance, the demarcation of the area, to which a science actor belongs, is of the greatest importance. This poster presents a method based on searches on Boolean combinations of medical subject headings (MeSH-terms) in a combined Web of Science (WoS) – Medline database. The construction of the MeSH area definitions is described and recall is discussed and compared to other methods.

Konferensbidrag (refereegranskat)abstract
- Not knowing enough about the similarities or differences of citation structures between different types of publications creates problems related to whether citation maps of research fields based on Web of Science/ISI data are representative of research fields as a whole or if they are a representation of how WoS perceives the field, not the least in the humanities and the social sciences. To investigate this problem, the citation structures in entrepreneurship research were analyzed using citation data both coming out of WoS-indexed journal articles and citation data from 12 entrepreneurship research handbooks. The datasets were analyzed by studying the age of references, the co-citation structures and also, citation overlaps. The results show substantial similarities between the two data sets: the distribution of the age of the references is almost identical, the co-citation structures in form of co-citation maps have strong similarities both in terms of identifiable networks as well as which cited authors are grouped together and there is also a strong citation overlap between the two different publication types.
