Some problematic aspects of using co-citation cluster time series to model the dynamics of research fields

Research Evaluation, 1991, vol. 1, issue 3, 155-159

Abstract: This study investigated whether bibliographic data alone provided reliable information on trends to answer the questions posed by policymakers. It was found that large areas of relevant material had been omitted which led to the false conclusion that two specialties were extinct after 1980 (the data was in fact found elsewhere but had not been linked to the trend being examined). However, the trend analysed had succeeded in listing the scientists who had been responsible for the development of the field. Modifications are suggested for the co-citation modelling technique that could make it more effective for studying specialty growth and change. Copyright , Beech Tree Publishing.
