Abstract
The information filtering apparatus has a configuration having a metric dividing section which divides a matrix indicating that what items a user needed and did not need into a plurality of matrixes, and a classification information filtering unit which calculates a plurality of classification necessities and a plurality of classification reliabilities using the plurality of matrixes divided in the metric dividing section.
Claims17
An information filtering apparatus comprising:
- a metric storage in which a result of determination on whether a presented item is necessary or unnecessary is stored in the form of a metric signal calculated from a key word signal contained in the presented item;
- metric dividing means for fetching the metric signal from said metric storage, and dividing the metric signal for each predicted field to generate a classification metric signal;
- classification filtering means for rearranging an order of presenting input items which are input from a storage using a magnetic or optical medium, or an information communication network, using a divided metric signal;
- and
- presentation means for presenting items for each field according to the order rearranged in said classification filtering means.
