1. An information processing system, comprising: a field-of-censorship generation device for decomposing individual person generated data generated by an individual person into a plurality of decomposed data that can identify the meaning, extracting data that satisfies both a predetermined relation condition regarding an object indicated by each of the decomposed data and a predetermined characteristic condition regarding the object, and generating a collection of first extracted data extracted thereby as a field of censorship; and a device for making particularity available for extracting data that satisfies a particular condition indicating a predetermined particularity in connection with the object from the collection of the first extracted data, and detecting the predetermined particularity from second extracted data extracted thereby to make it available.
