METHOD AND APPARATUS FOR SEARCHING FOR SIMILAR PATENT BASED ON ELEMENT ALIGNMENT
First Claim
1. A method of searching for a patent similar to a query patent on the basis of element alignment, the method comprising:
- extracting element from an input query patent, extracting search word for a similar patent search from the extracted element, and searching for a similar patent;
aligning the element of the query patent with element of a similar patent obtained through the search and calculating a matching rate of the element of the similar patent to the element of the query patent;
determining whether any element is unmatched between the element of the query patent and the element of the similar patent and extracting an unmatched element;
determining whether an additional search is necessary and allowing a user to input a paraphrase suitable to additionally search for the unmatched element when an additional search is necessary; and
receiving the paraphrase input by the user, replacing the unmatched element with the received paraphrase, and returning to the searching for a similar patent using the paraphrase used for replacement.

Abstract
Provided are a method and apparatus for searching of a similar patent based on element alignment. The method includes: extracting patent elements from an input query patent, extracting search words from the elements, and searching for a similar patent; aligning the elements of the query patent with elements of a similar patent obtained through the search and calculating a matching rate; determining whether any element has been unmatched between the elements of the query patent and the elements of the similar patent and extracting an unmatched element; determining whether an additional search is necessary and causing a user to input a paraphrase suitable to additionally search for the unmatched element when an additional search is necessary; and receiving the paraphrase input by the user, changing the unmatched element for the received paraphrase, and returning to the searching for a similar patent using the changed paraphrase.

13. An apparatus for searching for a similar patent on the basis of element alignment, the apparatus comprising:
-
a means configured to be connected to a user equipment, receive a query patent input to the user equipment, extract element of the query patent, extract search word for a similar patent search from the extracted element, and search for a similar patent; a means configured to align the element of the query patent with element of a similar patent obtained through the search and calculate a matching rate of the element of the similar patent to the elements of the query patent; a means configured to determine whether element is unmatched between the element of the query patent and the element of the similar patent and extract an unmatched element; a means configured to determine whether an additional search is necessary and transmit a paraphrase input user interface (UI), which allows a user to input a paraphrase suitable to additionally search for the unmatched element, to the user equipment when an additional search is necessary; and a means configured to receive the paraphrase from the user equipment, replace the unmatched element with the received paraphrase, and cause the means of searching for a similar patent to search for a similar patent using the paraphrase used for replacement. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
