INDICATING RELATIONSHIPS AMONG TEXT DOCUMENTS INCLUDING A PATENT BASED ON CHARACTERISTICS OF THE TEXT DOCUMENTS

摘要

Plural characteristics of text documents are extracted, where the plural characteristics include citations to or from other text documents and at least one other characteristic. At least one of the text documents is a patent. Each of the text documents is associated with a corresponding collection of the plural characteristics. An output is generated using the collections of the plural characteristics, where the output indicates relationships among at least a subset of the text documents including the patent based on the collections of the plural characteristics.
