1. A system for drawing a patent map using a technical field word, comprising:
- a storing unit for receiving a download of patent information from at least one patent information providing site and storing it;
an extractive object selection and sentence extracting unit for selecting at least one word extraction object and extracting a sentence of the selected word extraction object from the patent information stored at the storing unit;
a clause separating unit for separating, in a unit of a clause, the sentence of the extractive object selected in the extractive object selection and sentence extracting unit;
a word extracting unit for counting the number of words in the sentence which is separated in a unit of a clause in the clause separating unit, calculating weight values and the sum of the weight values by respective words, and extracting the word;
a word matching unit for matching the word extracted from the word extracting unit, with a patent;
a patent map drawing unit for drawing a patent map referring to data matched in the word matching unit; and
a patent map drawing controlling unit for controlling the word extraction object of the extractive object selection and sentence extracting unit.

Abstract
A system and a method for drawing a patent map using a technical field word are disclosed. In the system and the method, a word to be used for drawing a patent map is extracted by calculating weight values of significant words which are gotten by removing unnecessary words from patent data, and this extracted word is matched with a patent to draw the patent map.

-
a storing unit for receiving a download of patent information from at least one patent information providing site and storing it;
an extractive object selection and sentence extracting unit for selecting at least one word extraction object and extracting a sentence of the selected word extraction object from the patent information stored at the storing unit;
a clause separating unit for separating, in a unit of a clause, the sentence of the extractive object selected in the extractive object selection and sentence extracting unit;
a useless character eliminating part for removing a useless character corresponding to an already stored useless word list from a sentence based on a unit of a clause which is separated in the clause separating unit, and extracting the sentence based on a unit of a clause which has a removal of the useless character;
a word extracting unit for selectively receiving the sentence based on a unit of a clause from which the useless character is removed in the useless character eliminating unit, or the sentence separated in a unit of a clause in the clause separating unit, counting the number of words, calculating a weight value and a weight value sum per word, and extracting the word;
a word matching unit for matching the word extracted in the word extracting unit with a patent;

8. A method of drawing a patent map using a technical field word in a patent map drawing system, said method comprising the steps of:
-
a) receiving a download of patent information from at least one patent information providing site and storing it at an inside database;
b) selecting at least one word extraction object and extracting a sentence from the patent information stored at the inside database;
c) separating, in a unit of a clause, the sentence of the selected extractive object;
d) eliminating a useless character corresponding to an already stored useless word list from the sentence separated in a unit of a clause, and extracting the sentence of a clause unit which is gotten by removing the useless character;
e) selectively receiving the sentence based on a unit of a clause from which the useless character is removed, or the sentence separated in a unit of a clause, counting the number of words, calculating weight values and the sum of the weight values by respective words, and extracting the word; and
f) matching the extracted word with a patent, and drawing the patent map. - View Dependent Claims (9, 10, 11, 12, 13)
