- Abstract
- The paper presents a coword-analysis-based system called SDOC which is able to pupport the intellectual work of an end-user who is searching for information in a bibliographic database. This is done by presenting its thematical structure as a map of keyword clusters (themes) on a graphical user interface. These mapping facilities are demonstrated on the basis of the research field Social History given by a set of documents from the social science literature database SOLIS. Besides the traditional way of analysing a coword map as a strategic diagram, the notion of cluster relationships analysis is introduced which provides an adequate interpretation of links between themes
