Method of ordering document clusters without requiring knowledge of user interests |
摘要 |
A computerized method of ordering document clusters for presentation after browsing a corpus of documents that presents document clusters in a logical fashion in the absence of any indication of the computer user's interests. The method begins by grouping the corpus into a plurality of clusters, each having a centroid and including at least one document. Next, for each cluster a degree of similarity between that cluster and every other cluster is by finding a dot product between each cluster centroid and every other cluster centroid. The similarity information is then used to determine an order of presentation for the plurality of in a way that maximizes the degree of similarity between adjacent clusters.
