Description

  The present invention is an information retrieval for enabling a user to efficiently confirm and analyze information data retrieved from various information sources such as patent materials, paper materials, or technical materials. The present invention relates to a system and a search information display method based thereon.

  When building a document database such as a patent document database, a user generally approaches a CD-ROM or the like on which patent information is recorded in order to search for specific information, searches for desired information, and A lot of time is consumed because the information has to be processed and manually input to fit into a separate database managed by.

  In addition, since the processed patent information material is output in a predetermined format, it is different from the user's database format. Since the output conditions of the processed patent information material are limited, the user can output the patent on the screen. You must manually enter the informational material into your database. In addition, when a new search is performed, the previous search conditions and results cannot be easily used.

  In addition, since the retrieved information is output to the screen in a limited format, it takes a long time to scroll the screen and turn the page to analyze all the processed information. There is a problem.

  Accordingly, the present invention has been created to solve the above-described problems, and is an information classification method for automatically classifying information stored in an information source so as to match a user database. I will provide a.

  Another object of the present invention is to provide an efficient information search and analysis method using various search conditions and a search information display method.

  An information search method according to the present invention for achieving the above-described object includes a step of accessing an information source composed of a plurality of selectable fields via online or offline; Selecting and extracting specific fields to be satisfied; and displaying the contents of the extracted specific fields by grouping them based on the X-axis time and the Y-axis technical classification. And

  In addition, the information search system according to the present invention includes an access means for accessing an information source composed of a plurality of various selectable fields online or offline; and a specification that satisfies a search condition in the information source. Search and extraction means for selecting and extracting fields; and grouping display means for grouping and displaying the contents of the extracted specific fields based on the X-axis time and the Y-axis technical classification. Features.

  The information search and analysis method according to the present invention configured as described above provides information data by classifying the data into a solution problem and a solution, and the classified data is a file linked to a search data format. Stored in the format, the data can be easily accessed, repeated data search can be omitted, quick search is possible, and search result information data is standardized to increase the amount of analysis information data The data analysis results can be reduced and the information data analysis results can be output and displayed on the screen in various graphic formats such as pie charts, tree maps, trend maps, and bar charts. It becomes possible to confirm easily.

  In addition, the information search system according to the present invention and the search information display method using the information search system may approach various information sources such as patent materials, paper materials, technical materials, etc. via online or offline. A user who uses the information search system searches the information data satisfying the search condition and displays the searched information data with the specific search condition and time as the Y axis and the X axis. A large amount of information data retrieved from a display area of any size with the specific search condition such as the International Patent Classification Code (IPC) as the Y axis and the time such as the filing date as the X axis It is possible to efficiently confirm the trends and contents of related patents or technical information etc. Those which are very useful invention in made it possible.

  Hereinafter, preferred embodiments of an information search system and a search information display method according to the present invention will be described in detail with reference to the accompanying drawings.

  First, FIG. 1 is a flowchart illustrating an information classification method according to the present invention. As shown in FIG. 1, a predetermined patent technical field to be searched by a user first is selected (S1). ). Subsequently, the user determines the type (Type) of the information source used for the search (S2). That is, the information source is an external patent information database that can be accessed via the Internet or a computer communication network, or an optical disk such as a CD ROM (CD-ROM) that records patent information, an optical file, or a magnetic tape. Confirm whether it is such an internal patent information database.

  As a result of the confirmation, if the information source is an information source that is not directly compatible with the user's database or an external database, the desired information recorded in the information source is copied or downloaded to the user's database. It is stored in a separate connected recording medium (S4). However, when the information source is an internal database (in the example of S3), there is no need to download data.

  Next, it is determined whether a classification field to be classified by the user exists in the information (S5). If not, the user reviews the information to determine if a similar classification field exists or selects another classification field. (S6). Here, the classification field means a field in which the user attempts to classify data in the information source. For example, when the user attempts to classify patent information by field, the object, embodiment, and effect of the invention Claims, abstracts, drawings, international patent classification (IPC) numbers, application numbers, publication numbers, patent numbers, etc. can be classification fields.

  On the other hand, a predetermined information classification program programmed to be compatible with the user database automatically classifies the information using the classification field input by the user (S7). Subsequently, the user determines whether or not the classified data is reliable (S8), and if it is determined that the data is reliable, stores the classified information in the database (S9).

  Here, the information classification program can be programmed by the user. For example, if the information source contains both IMAGE information and text information, it can be programmed so that the IMAGE information and text information can be classified and stored separately. Also, if the information source contains only text information, the corresponding IMAGE information can be stored in a manner compatible with the database via COPY or download.

  On the other hand, FIG. 2 shows a block diagram of a network of an integrated database system according to an embodiment of the present invention that utilizes the classified and stored information. The system includes a plurality of search terminals (PC1) via the network. , PC 2...), A search server 100, a ROM (ROM) 20 in which system initialization and O / S drive programs are stored, a memory bank 21, and a central processing unit 40. When the classification program 41 driven by the central processing unit 40 is loaded into the memory bank 21 first, the central processing unit 40 executes the program 41 to perform classification, storage and retrieval of information data. Also, in order to accommodate the hard disk device (HDD) 30 in which the classified information data is stored and the program for classification / search is recorded, and the built-in CD ROM (CD-ROM) in which the patent information is recorded. A CD ROM driver 50 to be used is included.

  Hereinafter, the process of searching and classifying information from the information source according to FIG. 1 through the integrated database system of the present invention configured as shown in FIG. 2, and searching and analyzing the information through the database will be described in detail. explain. First, if the information source is inserted into the CD ROM driver 50 (for example, CD ROM) and the system is driven, the information source stored in the hard disk device 30 is loaded into the memory bank 21, and the central processing unit 40 is loaded. Thus, the classification program 41 is executed to perform the classification operation on the information sequentially read from the disc inserted in the CD ROM driver 50. That is, the classification program 41 selects at least one classification field by checking whether or not a specific classification field exists based on information read out from the disk and input.

  When a classification field is selected, the classification program 41 detects words and sentences having regularity based on the classification field 41, and classifies them based on this. For example, in Korean patent information data, if the document has a summary part, the summary part is classified as a solution to the summary claim, and if the document has no summary part, the first request is made. By classifying the first sentence of a term as a solution task and the remaining sentences as solution means, it can be utilized in basic data for analysis. In the case of Japanese patent information data, the summary field is composed of TO text and BY text in a certain form, so the TO text is a solution problem and BY text is a solution. In order to classify the object field of the invention, in the case of US patent information data, the first sentence in the whole sentence of the abstract is classified as a solution task and the remaining sentences are classified as solution means.

  As a result, the items of the solution problem and the solution means are extracted, classified and arranged by the patent information data as shown in FIG. 3, for example. As shown in FIG. 3, the patent information data includes the IPC code, the patent. Type (for example, Korea, US, etc.), publication date, application date, patent number (for example, KR5703859), inventor information, assignee or applicant information, solution, solution, title of invention, abstract, Includes detailed description, claims, drawings, and the like. FIG. 3 is an embodiment, and other data formats can be used.

  Further, patent information data is stored in the hard disk device 30, and the classification program 41 performs the sentence extraction and classification process according to the above-mentioned solution to all the information data read from the CD ROM, so that the disk 3 is arranged in the form shown in FIG. 3 and stored in the storage area of the hard disk device 40, the database for the integrated information management system is constructed.

  On the other hand, FIG. 4 shows a flow of a preferred embodiment of the information data search method according to the present invention. Hereinafter, the search method of the present invention will be described in detail with reference to the configuration of FIG.

  When searching for patent documents in the database of the integrated information management system (S41), the integrated information management database is constructed through the user executing the web browser installed in the search terminal (PC) first. Connect to the search server 100. (S42)

  If the user connects to the integrated information management system, the user is guided to a logon screen as shown in FIGS. 5A and 5B and enters a user name and password. The search server 100 loads the search engine 42 and the DB management program 43, which are programs for searching and analyzing materials, from the hard disk device 30 to the memory bank 21 to perform this.

  A search engine 42, which is an execution program in the search server 100, downloads JAVA APPLET constituting an integrated information management system to the search terminal via the network interface 10 when a connection is made from the search terminal. It becomes like this. If the user is successfully logged on to the system, the user can search for the desired patent by selecting Patent Search on the toolbar, while being guided to a screen explaining the system overview as shown in FIGS. 6A and 6B. .

  On the other hand, if a patent search is selected, a patent search menu including various fields that can be used to search for specific patent information is displayed under the control of the integrated information management search server 100 in FIG. And it comes to provide like FIG. 7B.

  Referring to FIG. 4, the user can input information into the patent search menu as shown in FIGS. 7A and 7B to start the desired patent search (S43). US and / or Japanese patents may be selected to be searched, or searched by inventor, patent application, keyword or search term, technical classification code or IPC, application date, and the like. In FIG. 7A and FIG. 7B, a US patent is selected, the technical classification code is set to G11B, and “video” is input as the search term.

  On the other hand, the search engine 42 program constructs a query for the condition value set by the user, and transmits the query to the DB management program 43 stored in the memory bank 21, so that the DB management program 43 searches the hard disk device 30 for information data corresponding to the questions received from the search engine 42. (S44) More specifically, the DB management program 43 searches whether the patent information data stored in the hard disk device 30 includes the search option selected by the user in FIGS. 7A and 7B.

  For example, if the user includes the term “video” and selects the US patent of the technical classification code of G11B, the DB management program 43 searches the hard disk device 30 for matching information (S45), and the hard disk 30 If the information existing in the screen matches the information selected by the user, the search result is output and displayed on the screen (S46). That is, the DB management program 43 transmits the search information data to the user search terminal (PC) via the network interface 10 and outputs and displays the information on the screen.

  Accordingly, the user can check the search result, and can determine whether to save the search term and the search result (S47). If it is decided to save the search terms and results, the search information is saved in a file (S48).

  For example, in FIG. 7, if the user selects (search object = US patent material) & (search word = 'video') & (search field = G11B *) for searching, the DB management program 43 Searches the hard disk 43 for information that matches the field as described above. The search character string is moved to the 'search formula' window located at the lower right corner of FIG. 7B. However, the user inputs a file name and selects the 'save list' button linked to the search formula to search the search character. Column and search string results can be saved.

  At this time, a specific directory is assigned to the area where the data is stored by the user who has logged in via the initial screens of FIGS. 5A and 5B. As a result, when the same user logs in for patent search, the user can search the previous search character string (and the result of the search character string) by simply inputting the file name. Also, the user can add other search conditions by looking at the previous search string.

  For example, when the user adds 'digital' as a search word, the search engine 42 program is a new search expression (search object = US patent material) & (search word = 'video' & 'digital') & ( Search field = G11B *) is configured, and the DB management program 43 can perform a new search using a new search character string and obtain a search result more quickly. The search result information data obtained in this way can be used in subsequent search formulas by specifying a new file name and newly storing it in the hard disk device 30.

  On the other hand, FIG. 8 shows the flow of a preferred embodiment of the information data analysis method according to the present invention which is performed by using the material obtained by the search condition as described above. 8 will be described in detail with reference to FIG.

  First, to analyze the data, the user selects patent analysis as shown in FIGS. 6A and 6B. By using the selection as described above, the user can know more precisely whether or not there is a technical trend and desired material for the searched patent information data. (S51) If the user selects patent analysis, a patent analysis menu screen as shown in FIGS. 9A and 9B is provided, but the patent information is in the form of a tree structure including the technical field code. Is displayed.

  If the patent analysis menu screen is used, the user can request a sample by inputting sampling conditions when a large amount of patent information data is searched (S52). In other words, the search engine 42 can preferentially extract the searched patent information data based on the sampling conditions input by the user (S54), and the analysis process is merely a sampling ratio of the patent information data. Is performed in proportion to

  For example, when the amount of information data to be searched is large, the user can enter a sampling rate of 5% with a specific year as a sampling condition. For example, if there are 100 cases in FY 1981, 250 cases in FY 1982, 1221 cases in FY 1996, and the sampling rate is entered as 2%, two cases are selected arbitrarily in FY 1981. Five cases are arbitrarily selected in the fiscal year, and 24 cases are arbitrarily selected in the fiscal year 1996, and the analysis process is performed on the selected patent information data.

  In addition, if the sampling work can be performed based on a specific fiscal year, a technical field, etc., but the sampling work is specified based on each technical field, the sampling ratio is 5% for each fiscal year. Select 5% for the technical field.

  According to S52, the user can sample a plurality of pieces of patent information data to be analyzed, but if he / she does not wish to sample the data first, it analyzes all the data related to the specific analysis conditions. If desired, the analysis conditions of the information data can be adjusted using the patent analysis menu window as shown in FIGS. 9A and 9B. For example, if 'G11B' and '96 to 97 'are input and set as the technology classification code between the analyzers, information analysis is performed according to the input and set analysis conditions in the searched patent information data. (S53). That is, the analysis process is performed only on the patent information data for the period 96 to 97 including the G11B technical code as the technical classification code among the searched G11A and G11B.

  The search engine 42 program executed by the central processing unit 40 selects only the information data satisfying the input analysis conditions, and the search engine 42 receives the international patent classification code to which the selected information data belongs. A tree structure of (IPC code) is recreated and transmitted to the search terminal (PC) through the network interface 10.

  As a result, the international patent classification code for the information data is updated and provided in the form of a tree map (Tree Map) (graphic form) (S56), through which the user can approach the desired information step by step. As such, FIGS. 10A and 10B illustrate one embodiment of such a graphic format.

  In FIG. 10B, if the user selects G11B and 011 and subcodes 002, 003, and 004 among the international patent classification (IPC) codes output on the screen in the form of a tree map. The search engine 42 program selects only patent information data belonging to the technical field of G11B011 / 004. Then, the search engine 42 program sequentially displays the contents of the problem to be solved, the solution means item, and the patent number included in each selected patent information data on the search terminal (PC) as shown in FIG. By providing the data so that it is output on the screen, the user can accurately confirm the contents of the problem to be solved and the solution means item presented by the information from the patent information data belonging to the specific technical field.

  The analysis result can be configured in other graphic forms besides the tree map form. However, the analysis result can be converted into a pie map form as shown in FIGS. 11A and 11B according to a user's request, and FIGS. 12A to 12C. Graphic data is provided in various forms such as a trend map (Trend Map) and a bar map (BAR MAP) as shown in FIGS.

  Also, in FIG. 11A, each area or section of the pie chart is configured based on the ratio of patent information data to each technical field code, but FIG. 11A shows all subcodes for G11B. For example, since the region matches a plurality of patents belonging to each subcode, in FIG. 11A, the user can easily confirm that the subcode G11B-007 had a considerable number of patents, The same applies to FIG. 11B.

  Further, the ratio may be a statistical value for the analysis result information data, and may indicate a ratio of technical fields belonging to a lower stage of the upper technical code by setting the upper technical code of the currently selected technical field code to 100% as a whole.

  Then, regardless of the stage on the currently selected technical field tree, the total number of retrieved result data is 100%, and the technical field corresponding to the same stage on the currently selected technical field tree. For example, the user selects 005, which is a G11B sub-code, from among the retrieved materials in which the international patent classification code has a tree map form as shown in FIG. 9B.

  Thereafter, if the analysis result is requested in the form of a pie map, the search engine 42 program sets the analysis result to 100% of the search material having the technical classification code of G11B, which is the upper code of 005, as shown in FIG. 14C. All of the technical classification codes that are transmitted in the form and output to the screen or else the retrieved material, that is, not only the lower codes 005 and 001 of the selected technical classification code G11B, but also the lower codes 005 of G11B And 001, including the low-order codes of other technical classification codes G11A (for example, G11B 005, G11B 001, G11A 001, G11A 002) are transmitted in the form shown in FIG. Can be output on the screen. 14A and 14C are the same as FIGS. 14C and 14D.

  Referring to FIG. 8, when the user selects a specific area (for example, the pie chart area of FIGS. 11A and 11B) in the graphic form (S57), the central processing for executing the search engine 42 program is performed. The apparatus 40 selects only patent information data belonging to the selected area from the searched patent information data. Further, the central processing unit 40 extracts information of the selected information data (application date, applicant, name of invention, etc.) and transmits it to the search terminal (PC) via the network interface 10. The information is output on the screen (S58). As described above, it is possible to easily confirm the outline information for the information data included in the specific section or region selected by the analysis result provided by the user in the graphic form.

  In addition, after confirming the summary information (for example, FIG. 10A) output on the screen in this way, if the user requests browsing of more detailed information (S59), the central processing unit 40 is searched. By extracting only the requested specific information data from the information data and transmitting it to the search terminal (PC) via the network interface 10, detailed materials as shown in FIGS. 15A to 15C can be obtained. When the screen is output (S60) and the user requests enlargement of the drawing through the zoom or enlargement option with the detailed material output on the screen, the central processing unit 40 is as shown in FIGS. 16A and 16B. It is provided to the search terminal that requested the enlarged drawing data.

  On the other hand, FIG. 17 shows an operation flowchart of an embodiment of the information search display method according to the present invention. In the information search system to which the present invention is applied, various information sources selected and designated by the user can be set online or For example, information on patent documents that match the search conditions after checking the search conditions selected and specified by the user while accessing the database where the patent documents are stored online even when approaching via offline Data is retrieved (S10).

  If the retrieved information data amount exceeds the condition of the information data amount specified by the user (S11), for example, 1000 initially retrieved patent materials are checked. When the condition of the amount of information data specified by the user is 100, the information search system performs a series of operations for reducing and re-selecting 1,000 patent materials initially searched to 100. It will be performed (S12).

  For example, if the search conditions are the patent application date and the international patent classification code, IPC = HO4 *, the four grouped patent materials are selected and searched for 25 pieces based on the application date of each patent material. In order to screen and search a total of 100 patent documents, the screening process may be performed based on other search conditions specified by the user.

  On the other hand, if a predetermined number of patent documents are selected and searched, the X axis and Y axis of the display area for displaying the patent documents are determined (S13). For example, as shown in FIG. The Y-axis may be determined as an International Patent Classification Code (IPC), the X-axis may be determined as a patent application date (Appl.Date), and the size of the display area may be determined as the X-axis and the Y-axis. You can select based on the information displayed above, but for example all information on the X and Y axes will be displayed or selected to be much larger can do.

  In more detail, the grouped information data is displayed in the display area determined as described above. At this time, the user conveniently confirms the contents of the specific field included in the searched patent document. As shown in FIG. 18, a menu button (for example, 'more') that can be selected by the user is displayed together with a part of the characters (for example, 'more') as shown in FIG. S14).

  When the user selects and designates a menu button linked to a group (S15), after searching for any one of information data belonging to the group, that is, patent material, a specific field included in the patent material Is displayed through a large screen so that the user can confirm the details in more detail (S16).

  As a result, as shown in FIG. 19, more detailed contents for the first patent material of the first group can be displayed together with the drawing on the computer screen currently used by the user. When a specific key is input and a return to the initial display mode is requested (S17), in the information retrieval system, as described above with reference to FIG. 18, an initial display screen based on the X axis and the Y axis A series of operations to display is performed.

  In addition, when the user inputs any other key (S18), an arbitrary operation corresponding to the key is performed (S19). Therefore, the user using the information search system according to the present invention can: A lot of information data retrieved from the information source can be checked more efficiently through the display area determined by the X-axis and Y-axis. Can be analyzed accurately.

  On the other hand, the X axis of the display area can be variably set to a release date, a registration date, etc. according to the user's selection, and the Y axis can also be variably set to an arbitrary classification code etc. edited by the user. Can do.

  The information data displayed on the display area as a whole can be printed in a size much larger than A4 paper through a large size printer often used for auto CAD (Auto-CAD), etc. Information data can be displayed in various shapes on the display area.
