Document Type and Number:
WIPO Patent Application WO/2008/015907
Kind Code:
A1
Abstract:
It is possible to provide a device, a method, and a program for accurately outputting a
characteristic word and its characteristic degree in text mining. The device includes:
a text input device (10) having a reliability degree for inputting text data as
a mining object; a language processing unit (20) for performing language analysis
of the inputted text data having the reliability degree; a reliability degree
use characteristic word counting unit (30) for counting the number of characteristic
words in the input text and using the reliability degree and the statistical information
attached to the input text so as to correct the obtained counting result; a characteristic
degree calculation unit (40) for calculating the characteristic degree of each
of the characteristic words according to the calculation result after the correction;
a mining result output device (50) for outputting the characteristic degree
obtained a user operation input device (70) used by a user for input to set a language
process for the input text, to set a calculation method of the characteristic
degree to be obtained, and the like; a mining process managing unit (60) for transferring
the user instruction inputted via the user operation input device to respective
components; and a statistical information database (80) for recording and holding
statistic information indicating the property of an expected input text.
