Methods and computer-program products for organizing electronic documents

A method of organizing electronic documents of a document corpus, each electronic document comprising a predetermined classification code and having similarity values based on a similarity with respect to other electronic documents in the document corpus, the method comprising:

• for one or more predetermined classification codes:
• applying a classifier to each electronic document having the predetermined classification code to associate an evaluation code with each electronic document, wherein the classifier uses the similarity values of the electronic documents having the predetermined classification code;
• and
• for one or more predetermined classification codes, after determining an evaluation classification for each electronic document in the document corpus:
• applying a clustering algorithm to electronic documents having an evaluation code that is the same as the predetermined classification code to create a plurality of hierarchical clusters under the predetermined classification code, wherein the clustering algorithm uses the similarity values of the electronic documents in the document corpus.

A computer-program product for clustering electronic documents of a document corpus, the computer-program product comprising a computer-readable medium storing executable instructions that, when executed by a computing device, cause the computing device to:

• compare each individual electronic document in the document corpus with each other electronic document in the document corpus, thereby forming document pairs, wherein the electronic documents of the document pairs are compared by:
• calculating a similarity value with respect to the electronic documents of a document pair, wherein the similarity value is based on a plurality of attributes of the electronic documents in the document corpus, and the plurality of attributes comprise a citation attribute, a text-based attribute and one or more of the following attributes:
• an author attribute, a publication attribute, an institution attribute, a downloads attribute, and a clustering results attribute;
• and
• associating the similarity value with both electronic documents of the document pair;
• and
• apply a clustering algorithm to the document corpus using the similarity values to create a plurality of hierarchical clusters.
