英文抄録

A method is described for deriving the knowledge structure in the specialty. The knowledge structure is represented by the key concepts and the relationship between them in the specialty. The key concept is derived from the analysis of the passages which cite the core (highly cited) document in the specialty. The relationship between the key concepts is derived from the analysis of the passages which cite the two core documents together. The content analysis of the co-citation context reveals how the key concepts represented by the core documents are associated.

The method is applied to the co-cited documents in the specialty of library and information science. The knowledge structure is derived based on the original co-citation map. The characteristic of the resulting knowledge structure is discussed and compared with that in the specialty of biomedical science. It is found that the degree to which the consensus of the relationship between the key concepts in the specialty of library and information science is lower than in the specialty of biomedical science.
