Method and device for text filtering to extract features from documents has a concept document matrix updating device, a base vector calculating device and a feature extracting device for processing data via iteration processes.
Method and device for text filtering to extract features from documents has a concept document matrix updating device, a base vector calculating device and a feature extracting device for processing data via iteration processes.
A feature-extraction control device (200) has a concept document matrix updating device (210), a base vector calculating device (220) and a feature extracting device (230). A first data file (100) handles concept document matrices from data collected for a document. A second data file (300) handles base vectors. A third data file (400) handles features. A fourth data file (450) handles standardizing parameters. Data is processed in a series of iteration processes.
