Description

The present invention relates to a technical research support device, a technical research support method, and a technical research support program.

In recent years, there has been proposed a system for searching a large number of documents for documents whose contents are close to conditions (for example, Patent Document 1). Patent Literature 1 describes that the weight of each document is calculated from the appearance frequency of keywords for each segment that constitutes each part of the document, and the similarity is scored according to a predetermined standard based on the weight. . According to the system of Patent Literature 1, since the degree of similarity is scored for each segment of a document, it is possible to perform a reliable search even if the content close to the condition is described only in part of the document.
In addition, when searching patent documents as a search target, a logical combination relationship (specifically, logical product (AND) or logical sum (OR), etc.) of search keywords is specified as a search condition, and the search condition is A system for extracting satisfying prior patent documents has been provided (eg, Non-Patent Document 1). According to the system described in Non-Patent Document 1, a user can improve search accuracy by inputting all possible synonyms of a search keyword and specifying a logical sum (OR).

However, based on the system of Patent Literature 1, there may be a case where a document is retrieved that has a low degree of similarity as a whole because content close to the condition is described only in part of the document. Furthermore, if a document not intended by the user is retrieved, it will be necessary to start again from the beginning when selecting keywords, phrases, sentences, etc. used as conditions. Then, selection of retrieval conditions is repeated many times until a document having contents close to the conditions is retrieved. This takes a lot of time and places a heavy burden on the user.
In addition, in the system of Non-Patent Document 1, it takes effort to think of synonyms for a search keyword, and tends to depend on search skill and technical knowledge. Therefore, there is a demand for a document information evaluation apparatus that allows even users with little experience in searching and technical knowledge to perform a certain level of searching or evaluation.

Wherein, the feedback information receiving sub-module provides a user operation entrance to the user interface by providing a user operation entrance by displaying an operable button on the user interface of the user terminal; It may include providing a user interaction entry by prompting the user interface for voice input.

The data center network is operably connected to the destination referred to herein as the Zuri(R) system, such as the Zuri(R) system.
Steps S16 and S17: The user terminal determines whether operations such as detailed description, summary, and printing have been performed on the screen displayed on the external computer as shown in the figure (step S16). If it is detected, it can be determined that "a third party is paying attention", so the new evaluation index of the corresponding cited patent application in the evaluation result D/B2 is set to k4 (constant) > 1, for example, (new evaluation index C)=(original evaluation index C)×k4.

This symbol is set by a user who has previously learned how to search documents using a user terminal in order to customize the search conditions to a desired state. In the search processing of ", a search condition that a maximum of five words including these words may exist between the attention word "vehicle" and the word "horizontal direction", and the attention word " It indicates that a search condition that a maximum of five words including these words may exist between "vehicle" and the word "yaw rate" has been set.

For example, a sentence to be subjected to text mining in the step, which includes a user-desired word of interest previously set on the search expression input screen (Fig. a second detection means for detecting the yaw rate of the vehicle; and attitude control means for controlling the attitude of the vehicle during travel based on the lateral acceleration and the yaw rate. , the attitude control means .

The A data search condition specification screen in the figure has a [Back] button, a notification department specification section for specifying the department that submitted the invention, an in-house inventor specification section for specifying an in-house inventor, and a person in charge of intellectual property. Intellectual property manager designation section, intellectual property evaluation designation section that designates intellectual property evaluation, research theme number designation section that designates research theme number, and vehicle type that designates the vehicle model to which the invention is applied (including plans) The model designation part, the department keyword designation part that designates the department keyword, the foreign application presence/absence designation part that designates whether or not there is a foreign application, the examination request/nonexistence designation part that designates whether or not an examination request is made, and the examination request date is specified as the year and month. It has an examination request date designation section for designating a period of days, a right life and death designation section for designating whether the right is alive or dead, a result compensation presence/absence designation section for designating whether or not there is performance compensation, and a [clear] button.

Here, in the magnetic disk, there are a display process for displaying the display screen during the search process shown in the figure and a search result (not shown) on the screen of the display device, and a control to the CD-ROM device based on the instruction information. An information search/read process for sending a signal or receiving information searched/read out from the CD-ROM by the CD-ROM device, and an adjacent search value (search condition) continuously input according to a search process procedure described later. A type determination process that determines whether or not search items (types) are the same according to the input order, and based on the determination result, a connection condition according to the difference (relationship) of the search items, such as an OR condition operator "+ ” or an operator “*” of an AND condition to generate a search expression by connecting and combining the search values.

Here, the search engine (publicly known document database search unit) 21A searches for publication data (bibliographic items) corresponding to the search condition in response to a search request (search condition) for the known example DB 2A-1, 2A-2. Then, n types (n is an integer of 2 or more) of bibliographic items are obtained as search results (publicly known document search results: hereinafter also referred to as publication search data), and the search engine (application document database search unit) 21B In response to a search request (search condition) for the original application DB2B-3, search the original application DB2B-3 to obtain m types of bibliographic items (m is an integer of 2 or more, and m=n or m≠n) are obtained as search results (application document search results: hereinafter also referred to as original patent management data).

Here, by operating the input section, when a search keyword to be indexed is input using a wildcard, for example, "TOKUHO 0?-??????", the top of the document data file to be saved is The pointer is sequentially set to move from the characters, and the data corresponding to the keyword "TOKUHO 0?-??????" is retrieved (steps S9, S10, S11, S12→S14, S15), and the data corresponding to the keyword. is searched, for example, in the case of the publication data collection file shown in the figure, the page line numbers P1L1, P1L9, P2L4, . . . **8", "TOKUHO 01-12*45", "TOKUHO 09-87***", and so on are associated with an index (step S12→S13).

The input unit is equipped with character/symbol input keys and numeric keys for inputting arbitrary characters and symbols, and also has a data import function for storing data files read via the storage medium reading unit into the storage unit. , a file saving function that saves a data file created according to the operation of the letter/symbol/number key in the storage unit, a list display function that displays a list of the data files saved in the storage unit, and a list of displayed data Function keys for activating various functions such as the file open function that opens an arbitrary data file from among files, cursor keys for moving pointers and cursors on the display screen, data selection, etc. and a mouse are provided.

Here, the patent asset valuation device allows the user to select a desired product from the target patent-using product list included in the target patent-using product list screen example via the input unit (in this figure, the screen After accepting the operation of checking the check box on the left), and then accepting the operation of pressing the comparison display button, the display switches to the comparison display screen showing the degree of matching between the target patent and the product, and the target patent The feature of each elemental technology of the selected product is compared with the feature of each elemental technology of the selected product and presented to the user.

Here, in the case where the publication data collection file is in a document format in which the publication number to be the heading is described at an arbitrary line position in the page, if it is determined to be a document format data file, the search keyword to be indexed is displayed on the display as a search function that can use a wild card (step S6→S9).

A search keyword is entered for each element that constitutes an invention.

Here, the patent information substance data recorded in the patent information substance data recording unit includes a plurality of search keys that characterize the data file for each data file and serve as clues for knowing the contents of the data file. Patent information, which is one of the substance data of patent information, is a type indicating four legal divisions, IPC, FI, F term, application number, publication number, international application number, international publication number, publication number, publication number, registration number , priority claim number, related application number, trial number, filing date, publication date, registration date, inventor name, applicant name, each right holder name, invention title, keyword, etc. I'm in.

Factors that determine the degree of contribution of each member stored for each member in the member information storage means include, for example, the royalty paid to the administrator by each member using the intellectual property rights for which compensation is to be determined. and the number of license agreements that each member currently has or has had in the past with the administrator, including intellectual property rights other than the intellectual property rights for which consideration is determined, and each member determines the consideration It includes the total amount of royalties paid to administrators, including the use of intellectual property rights other than the target intellectual property rights, and the number of intellectual property rights contributed by each member as a contributor.

The reason for creating a set by removing one formula from all the formulas created for each hierarchical keyword string in the keyword search formula is that the constraint by the hierarchical keyword string corresponding to the removed formula is eliminated and a new keyword is created. In the description of this application, a set that does not use one formula is created in order from the above formulas, K1, K2, K3, and K4, and the logical product of the formulas in the set is used. However, the number of formulas that are not used sequentially is not necessarily one, and may be set to an appropriate number in a trial search.

S17, in the second search for extracting the screening patent document set from the patent document set, the search target document set is a logical difference set between the patent document set and the A*S name set screened in the previous step. (The set is given the name of the set of patent documents and stored in the storage device as a data object of the set of patent documents.) The search item is the keyword of the abstract, and the search keyword is the relevant/unsuitable documents by keyword of the abstract of the set of patent documents. Logical OR of keywords selected by the searcher from among the keywords selected from the range of keywords selected using the ratio of relevant/non-conforming documents in the ratio table (see Fig. 22 as an example) as an evaluation scale, and keywords that partially match the keywords, and the search method is an exact match. Create a search formula (see FIG. 23 as an example) to be searched, perform a search with the search formula, and set the hit document set (as a data object of the patent document Let H2 be the number of documents in the set of matching documents extracted by screening (stored in the storage device as a data object of the set of patent documents by assigning the name of the summary matching set to the set).

S19, the third search for extracting the screening patent document set from the patent document set is the logical difference between the patent document set and the B*S summary set screened in the previous step. A set (a patent document set name is given to the set and stored in a storage device as a patent document set data object), the search item is a keyword in the scope of claims, and the search keyword is a keyword in the scope of claims of the patent document set. Keywords selected by the searcher from the range of keywords selected by using the ratio of suitable/unsuitable documents in the ratio table of suitable/unsuitable documents as an evaluation scale, and the logical sum of keywords that partially match the keywords. Create a search formula to search, execute a search with the search formula, and screen the hit document set (give the set a C*S claim set name and store it in a storage device as a patent document set data object) Let H3 be the number of documents in the extracted matching document set (the set is given the name of the request matching set and stored in the storage device as a data object of the patent document set).

S21, the fourth search for extracting the screening patent document set from the patent document set is the logical difference between the patent document set and the C*S claim set screened in the previous step. A set (the name of the patent document set is given to the set and stored as a data object of the patent document set in the storage device), the search item is a keyword of the full text of the text, and the search keyword is a match by keyword of the full text of the patent document set.・Search using the logical sum of the keyword selected by the searcher from among the keywords in the range of keywords determined by the proportion of relevant and non-conforming documents in the non-conforming document ratio table and the keyword partially matching the keyword, and the search method being an exact match search. Create a formula, perform a search with the search formula, screen a set of hit documents (give the set a D*S full-text set name and store it in a storage device as a data object of the patent document set), Let H4 be the number of documents in the extracted matching document set (the set is given the name of the full-text matching set and stored in the storage device as a data object of the patent document set).

Therefore, the search execution unit refers to the text information of the patent documents, and uses this regularity to, for example, use the noun immediately before the comma, the noun before the phrase "to,", or By extracting nouns immediately preceding fixed phrases such as ",", "consisting of", "comprising", "including", "consisting of", "comprising", etc., the claim It is possible to extract broader concept keywords, . . .

Then, when the matching rate calculation for all the patent documents accumulated in the patent document accumulation database is completed (the result of the step is YES), the search execution unit calculates the patent based on the matching rate stored in the memory. Among all the patent documents accumulated in the document accumulation database, extract documents with a matching rate higher than a predetermined value, or a predetermined number of documents in descending order of the matching rate, and output to the display unit ( step S9).

In the similar patent specification search execution unit, the search term/related term group extracted by the search term/related term extraction unit and the index ( By sequentially collating the terms described in the claims and the terms described in the concept description, the retrieved patent specifications of similar claims are output as similar patent specifications.

When creating an upper and lower thesaurus using a computer or the like, for example, "B such as A", "B such as A", "B such as A", " A super-lower thesaurus may be created by extracting sentences containing the expressions "B like A" and "B like A", treating the words as subordinate concept words, and associating the words as superordinate concept words.

Then, by referring to the table stored in the storage unit, the wordings of the constituent elements in the extracted claims are replaced with higher-level or lower-level wordings, and the patent specification is searched based on the replaced wordings. By doing so, it is also possible to automatically extract constituent elements and effects of intermediate concepts that are not claimed in the scope of claims.

Here, the broader concept term is a concept that collects and integrates similar or similar items, or a term that represents a concept that integrates multiple items based on a certain common property, and means a lower concept. A term that means a concept with a higher degree of abstraction than a term.
