Abstract
A text processor or text processing software determines a significance value of a search word based upon the word occurrence in a specified part of a predetermined text database. After a search request is inputted and parsed, each of the search word candidates is searched in a specified portion of the predetermined text database. For example, a search word candidate is searched only in a near portion or area of the predetermined text database to determine its specific area occurrence value. The above determined specific area occurrence value is used in the subsequent steps or tasks to accomplish a desired task.
Claims66
A method of processing text data, comprising the steps of:
- inputting text data;
- parsing the text data into word candidates;
- removing predetermined words from the word candidates;
- specifying an area of a predetermined text database;
- and
- determining a specific area occurrence value of each of the word candidates in the specified area in the predetermined text database.
A method of processing text data, comprising the steps of:
- inputting text data;
- parsing the text data into word candidates;
- removing predetermined words from the word candidates;
- determining a first text database occurrence value of the word candidates in a first text database;
- determining a second text database occurrence value of the word candidates in a second text database;
- determining a database occurrence value based upon the first text database occurrence value and the second text database occurrence value in a predetermined manner;
- selecting search words from the word candidates based upon in part the database occurrence value;
- and
- extracting sentences from a predetermined text database based upon the selected search words.
A computer program for processing text data, performing the tasks of:
- inputting text data;
- parsing the text data into word candidates;
- removing predetermined words from the word candidates;
- specifying an area of a predetermined text database;
- and
- determining a specific area occurrence value of each of the word candidates in the specified area in the predetermined text database in a predetermined manner.
29 The computer program for processing text data according to claim 28 wherein the specific area occurrence value is determined according to a following equation:
- 22 the specific area occurrence value = a number of documents including the word candidate in either one of the summary area and the header area / a number of documents including the word candidate in an entire portion of the predetermined text database .
A computer program for processing text data, performing the tasks of:
- inputting text data;
- parsing the text data into word candidates;
- removing predetermined words from the word candidates;
- determining a first text database occurrence value of the word candidates in a first text database;
- determining a second text database occurrence value of the word candidates in a second text database;
- determining a database occurrence value based upon the first text database occurrence value and the second text database occurrence value in a predetermined manner;
- selecting search words from the word candidates based upon in part the database occurrence value;
- and
- extracting sentences from the predetermined text database based upon the selected search words.
A apparatus for processing text data, comprising:
- an input unit for inputting text data;
- a search word selection unit connected to said input unit for parsing the text data into word candidates, said search word selection unit removing predetermined words from the word candidates;
- an area specification unit for specifying an area of a predetermined text database;
- and
- a specific area occurrence determination unit connected to said search word selection unit and said area specification unit for determining a specific area occurrence value of each of the word candidates in the specified area in the predetermined text database.
A apparatus for processing text data, comprising:
- an input unit for inputting text data;
- a search word selection unit connected to said input unit for parsing the text data into word candidates, said search word selection unit removing predetermined words from the word candidates;
- a database occurrence determination unit connected to said search word selection unit for determining a first text database occurrence value of the word candidates in a first text database and a second text database occurrence value of the word candidates in a second text database, said database occurrence determination unit further determining a database occurrence value based upon the first text database occurrence value and the second text database occurrence value in a predetermined manner, wherein said search word selection unit selects search words from the word candidates based upon in part the database occurrence value;
- and
- a text selection unit connected to said search word selection unit for extracting sentences from the predetermined text database based upon the selected search words.
