Abstract:
1. A computer automated method of clustering a plurality of documents, each document including input space data and output space data, the method comprising: for each document in the plurality of documents, reading the input space data of the document from memory or storage; computing an input space similarity measure between the document and other documents of the plurality of documents using a computing device; aggregating the document into a first plurality of clusters based on the input space similarity measure; storing the first plurality of clusters in a database; for each cluster in the first plurality of clusters, reading the output space data of the documents in the current cluster of the first plurality of clusters; computing an output space similarity measure for the plurality of documents in the current cluster using the computing device; and maintaining or subdividing the current cluster in the first plurality of clusters based on the output space similarity measure, wherein aggregating the documents into a first plurality of clusters comprises:
