NRI Cyber Patent Ltd. (Tokyo, Seiji Takano, President & CEO) has launched a concept search service in English, which covers patent information from 40 countries. This is an additional function in the already provided patent information service called "NRI Cyber Patent Desk" (http://www.patent.ne.jp). With this new function the meaning of entered paragraph for a search is analyzed and matched with the patent information. This is the first service ever provided in the world that makes possible the concept search of patents information from such a many countries.

With ordinary keyword search engines, it was necessary to input a technical word accurately to search for foreign patent information in the original language, which has been done by skilled professionals.

NRI Cyber Patent Desk has been offering the concept search service in Japanese for domestic patents since July 2000. Our new service in English is to make it possible to retrieve the information with scores (the higher, the more relevant) even with an abstract keyword/paragraph. The search from approximately 7 million information is completed in few seconds.

In addition, NRI Cyber Patent Desk will provide a new service to search similar patent information with a single click. With this function, it will be feasible to obtain information relating to a certain patent without entering keywords in original languages.

About Concept Search

Weakness of Keyword Search

• It searches the exact keyword, thereby if the search result is less or more than expected, another keyword must be entered.
• The result depends on whether the exact keyword exists or not, not on the degree of similarity of the keyword and the output.

To overcome the above weakness, the concept search technology is adopted.
The concept search engine decides the vector for documents by using "stem vector" with the function as a dictionary. When searching for information, it decides query context vector by categorizing the keyword entered as a source for searching based on the stem vector. The products of search vector and the document vector group will be computed to output lists of documents in order of high scalar. By using this technology, it is made possible to retrieve related documents with scores.
