Abstract:
1. A document data analysis apparatus, the document data analysis apparatus being connected to a database storing a plurality of document groups in which citation relationships are defined, each of the plurality of document groups comprising a plurality of documents, comprising: a receiving unit that receives an analysis condition comprising at least one of a document search condition and a specification of a seed document group based on at least a search key word and a bibliographic condition, the seed document group being a seed of an active propagation process; a determining unit that determines an initial active value of each of the plurality of documents based on the analysis condition; an executing unit that executes the active propagation process based on the initial active value and a plurality of citation relationships by evaluating concurrently a first and second groups of documents per each document of the seed document group, the first group of documents associated with a document of the seed document group as the cited document, and the second group of documents associated with the document of the seed document group as the citing document and updating the seed document group based on the evaluation; a terminating unit that terminates the active propagation process once the result reaches equilibrium; and an output unit that outputs a result of the active propagation to a display, wherein the output unit outputs the result so that the display displays an icon for each of the plurality of documents in the equilibrium result of the active propagating process, a size of the icons varies depending on the equilibrium result for each of the plurality of documents in the equilibrium result.
