Abstract
The subject matter described herein relates to methods, systems, and computer readable media for dynamic cluster-based search and retrieval. An example method for dynamic cluster-based search and retrieval occurs at a server. The method includes: retrieving document data for a plurality of documents related to user input; performing keyword discovery on the document data for determining term related frequency metrics and document related frequency metrics; representing the plurality of documents as a term-document matrix based on the term related frequency metrics and the document related frequency metrics; reducing, using latent semantic analysis, the dimensionality of the matrix; clustering, using a k-means clustering algorithm and the dimensionally reduced matrix, the plurality of documents into clusters; and sending presentation information to a client device for displaying visual representations of the clusters, wherein each visual representation is associated with one or more of the plurality of documents.
