Abstract

This article proposes a new model, based on fractal geometry, for clusters of relevant documents. It reflects the relatively simple iterative search process used by interactive onlinesearchers. The untested model has the additional sttractive features of high-lighting the logarithmis growth of clusters, which produces complexities in relevance judgements and document clusters not realized by typical models. It indicates that clusters formed using dynamic search strategies appear topoligical distinct, indecomposable, and result from chaotic processes. The model also provides an intuitive definition and representation of cluster dimension which differentiates, where typical models do not, between them. The fractal model, then, gives an indication of what I believe are the limits on clustering relevant documents
