ABSTRACT:
A machine-executable attribute extraction method comprising: extracting, vis-à-vis a plurality of documents in the archival memory (that also stores registration dates and attributes of the documents) having registration dates falling within a desired time period, feature words for each attribute value of the corresponding attributes of the plurality of documents; registering, into the work memory, the desired time period, and the extracted feature words for each attribute value of the corresponding attributes of the plurality of documents; determining, amongst the extracted feature words in the work memory, first feature words for which the attribute has a first attribute value and second feature words for which the attribute has a second attribute value; calculating a similarity between the first feature words and the second feature words; judging whether the similarity satisfies a condition; and outputting the second attribute value when the similarity satisfies the condition.
