TAXONOMY GENERATION

摘要

Systems and techniques to generate a term taxonomy for a collection of documents and filling the taxonomy with documents from the collection. In general, in one implementation, the technique includes: extracting terms from a plurality of documents; generating term pairs from the terms; ranking terms in each term pair based on a relative specificity of the terms; aggregating the ranks of the terms in each term pair; selecting term pairs based on the aggregate rankings; and generating a term hierarchy from the selected term pairs.
