Measuring the diversity of ecological research
is latent semantic analysis a suitable tool?
Latent Semantic Analysis (LSA) has recently been proposed as a tool for analyzing research diversity and for extracting latent themes from a set of documents. Using ecological research as an example, this study scrutinized the suitability of LSA for achieving these goals. In addition to the already tested calculation of research diversity based on co-citation of references, three other document properties – title, abstract, and keywords – were used and compared to the results of the reference-based approach. The results of the analyses suggest that LSA is – in its current state – no very suitable tool for either analyzing research diversity or extracting latent themes from bibliographies. Therefore, other options of measuring research diversity should be evaluated in the future.
