BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart showing an information classification method according to the present invention. As shown in the figure, first, the user selects a search field to be searched (S1). Next, the user determines the type of information source utilized in the search (S2). That is, it is determined whether the information source is an external patent information database accessible by Internet or personal computer communication, a CD-ROM storing patent information, or an optical disc (S3). Here, if the information source is not a recording medium such as a CD-ROM, an optical disk and a magnetic tape, but an external database that can be accessed only through computer communication, or it cannot be directly exchanged with a user database. If it is an information source, the desired information recorded in the information source is copied or downloaded and stored in a separate recording medium linked to the user's database (S4).

Next, the symbols described in the information to be searched,
One of characters, words and sentences is input and set as a classification field, and the user determines whether or not the classification field to be classified exists in the information source (S
5) If it does not exist, the user inserts a classification field at the corresponding position of the information so that the user can review the information and exchange it with his database (S6). Here, more specifically, the classification field refers to a field in which the user tries to classify the data in the information source. For example, when the user tries to classify the patent information by field, the purpose of the invention, the implementation Form, effect, claims, abstract, drawing, International Patent Classification (IPC) number, application number,
The publication number and the patent number are the classification fields. When the preparation for classifying the information according to the field is completed in this way, the information is automatically classified according to the predetermined classification field according to a predetermined information classification program programmed so as to be exchanged with the user's database (S).
7).

Next, after judging whether the data of the classified information is reliable (S8), it is stored in the database (S9). At this time, the information classification program can be programmed arbitrarily by the user. For example, if the information in the information source includes image information and text information together, the image information and text information can be programmed to be sorted and stored separately. If the information source includes only text information, the corresponding image information can be copied or downloaded from an external information source and stored so as to be exchanged with the database.

FIG. 2 shows a network configuration of a database system as an embodiment of the present invention in order to utilize the classified and stored information as described above. Figure 2
As shown in FIG. 2, a plurality of search terminals (for example, using a web browser) PC1, PC2, through the network
Network interface 10 for exchanging data with ...
ROM 20 for storing system initialization and OS driving program, memory bank 21 for loading the program, executing the program loaded in the memory bank 21 to perform classification, storage and retrieval of information data Central processing unit (CPU) 40 and a hard disk drive (HDD) that stores a program for storing, classifying, and searching the classified information data.
30 and a CD-ROM driver 50 into which a CD-ROM containing patent information is inserted and mounted.

Hereinafter, a process of retrieving and analyzing information using the integrated database system according to the present invention having the above structure will be described. First, when an information source, for example, a CD-ROM is inserted into the CD-ROM driver 50 to drive the system, the search engine 42 program is loaded from the hard disk device 30 into the memory bank 21.

Next, the classification program 41 executed by the central processing unit 40 performs a classification operation on the information sequentially read from the discs inserted in the CD-ROM driver 50. That is, the classification program 41 checks whether or not there is a specific classification field for each piece of information read from the disc, and selects at least one or more classification fields according to the above-mentioned specific characters, When the classification field is selected, words and sentences having regularity are detected based on the selected field, and classification is performed based on the detected words and sentences.

For example, in the case of Japanese patent information data, in the abstract part, the fields for the purpose of the invention are TO text and B text.
Since the Y-sentence is configured in a predetermined form, the TO field is classified as the solution task and the BY-sentence is classified as the solution means by utilizing the predetermined format. And in the case of US patent information data, in the whole sentence of the abstract,
The first sentence is classified as a solution task, and the other sentences are classified as a solution means.

Further, in the case of Korean patent information data, a material having an abstract part is classified as a problem to be solved,
The claims are classified as a solution, but if the material has no abstract part, the first sentence of the claim is classified as a solution problem, and the other sentences are classified as a solution, and the analysis is performed. It can be used as basic data for.

As described above, the items of the problem to be solved and the solution means are extracted and classified as the classification field, and the patent information data whose contents are reconstructed as shown in FIG. 3 is stored in the hard disk device 30. Since the classification program 41 performs a corresponding sentence extraction and classification process by the above-mentioned classification field on all information data read from the CD-ROM disc, all the patent document data recorded on the disc is shown in FIG. As shown in (1), the data is reprocessed and separately stored in the corresponding storage area of the hard disk device 40, and a database for the integrated information management system is constructed.

The information retrieval method according to the present invention will be described below with reference to FIGS. As shown in FIG. 4, the database of the integrated information management system constructed to have the classification item based on the classification field extracted by the reference word or the sentence structure selected from the contents of one or more items described above is used. When searching for material data (S41), first, the user searches the search terminal PC.
Web browser (WEB BRO) installed in (Fig. 2)
WSER) is executed to connect to the search server 100 (FIG. 3) in which the integrated information management database is constructed (S4).
2). Upon connection, the initial screen shown in FIG. 5 is displayed, and as a result, the search server 100 is the search engine 42, which is a program for searching and analyzing the material of the search terminal PC.
(FIG. 3) and the DB management program 43 (FIG. 3) are loaded from the hard disk device 30 into the memory bank 21 and executed.

When a connection is made from the search terminal PC, the search engine 42, which is an execution program in the search server 100, searches for a corresponding JABA APPLET constituting the integrated information management system through the network interface 10. Download to the terminal. Next, when the connection to the search server 100 is completed and the search is possible, the user inputs the user name and password on the initial screen as shown in FIG. 6 is provided, the search server 100 provides an initial screen for explaining the outline of the system as shown in FIG. 6, and when the user requests a patent search, a patent as shown in FIG. A search menu screen is provided.

Next, as shown in FIG. 4, the user inputs and sets the search conditions of the material data to be searched as shown below (S43), and the search target of the patent information data to be searched. , The technology classification code (IPC code or separately set code) and the search terms (keywords) and other input elements are selected (for example, search target: US patent, technology classification code: G11B *, search term: Input) to set.

Next, the search engine 42 program loaded from the hard disk device 30 into the memory bank 21 and driven by the central processing unit 40 makes an inquiry about the condition value set by the user, and already reads out the inquiry. In order to transmit the information to the DB management program 43 loaded in the memory bank 21, the DB management program 43 searches the hard disk device 30 for information data corresponding to the input and set inquiry.

Next, the DB management program 43 is executed as shown in FIG.
The patent information data corresponding to the received inquiry is searched from the hard disk device 30 (S44), that is, the DB management program 43 causes the hard disk device 3 to retrieve the patent information data.
Information data existing in the hard disk device 30 satisfies all the search conditions set by inputting from the enormous amount of patent information data stored in 0 (when the search condition of FIG. 7 is “AND” search). Check if

Next, as a result of the above search, the patent document data satisfying all the search conditions input and set by the user,
That is, when the U.S. patent information data including the term "video" and the technical field of which is G11B * is detected from the hard disk device 30 (S45), the DB management program 43 is searched for the number of search results, that is, searched. The total number of the obtained information data is transmitted to the corresponding search terminal PC through the network interface 10, and the number of the patent information data which matches the condition to be searched by the user is output as numerical data on the screen of the search terminal PC. It is displayed (S46).

Next, after visually confirming the numerical data based on the patent search result output on the screen as described above, FIG.
As shown in FIG. 7, when the user stores the search result in a file form (S47), the condition set by the user on the patent search menu screen shown in FIG. 7 is a predetermined search formula for displaying the search content. The contents of the “Search content” window converted and displayed in the form of a character string such as (search target = US patent material) and (search word = “video”) and (search field = G11B *) After being moved to the "Search Content" window of the storage window and the user has entered a file name and a description of the information content regarding it, he selects "List Storage". The search engine 42 program that has received the selection contents as described above newly stores in the hard disk device 30 the received search result and the index data that can index the information data obtained from the search expression (S48). ). At this time, the stored area is the directory specified by the user who has logged in through the initial screen of FIG. Therefore, in the future, when the same user logs in to search for a patent, desired information can be obtained from the information data relating to the same search condition by merely inputting a file name.

For example, when the search result information stored in the file format as described above is selected, the search expression and the index data of the search information in the selected file are stored in the memory bank 2.
When a new search condition is added to the search condition that is loaded and displayed by the user in that state, for example, when "digital" is added as a search word,
The search engine 42 program is a new search expression in which "digital" is added to the previous search expression (search target = US patent document) and (search word = "video &digital").
Since (search field = G11B *) is configured and the DB management program 43 is requested to perform a search, information data as a search result can be obtained more quickly.

The search result information data obtained as described above is also newly stored in the hard disk device 30 by designating a new file name as described above, so that it can be used for subsequent searches. Hereinafter, the information analysis method according to the present invention, which is performed by using the material obtained by the search condition as described above, will be described with reference to FIGS.

First, as shown in FIG. 8, in order to check the patent information data retrieved as described above, whether the user has a technical trend or a desired material, the material data analysis is judged. (S51). Search server 100 of FIG.
The information searched for in (1) is provided to the user as a patent analysis menu screen in which the corresponding technical field codes shown in FIG. 9 are displayed in a tree structure.

Next, the user inputs and sets the analysis conditions of the information data to be analyzed, that is, the value is input from the input items such as the technology classification code and the analysis period of the patent information data to be analyzed. For example, "G11B" as the technical classification code and "9" as the analysis period.
6 to 97 "is input and set, information data satisfying the analysis condition set by inputting from the retrieved patent information data, that is, 96 to 9 out of G11A and G11B retrieved in FIG. The analysis process is performed only on the patent information data including the G11B technology code as the technology classification code for the 1997 fiscal year (S53), when the number of retrieved information data is too large, as shown in FIG. After setting the sampling conditions such as international patent classification code and year on the menu screen of the patent analysis,
Request sampling (S52). Sampling will be described later.

Next, the search engine 42 program executed by the central processing unit 40 selects only the information data which satisfies the analysis condition set by inputting for analyzing the information data from the searched patent information data. From the network interface 10 by recreating the tree structure of the international patent classification code (IPC code) to which the selected information data belongs.
In order to update and provide the user with the international patent classification code for the information data based on the analysis conditions by transmitting it to the corresponding search terminal PC via S5 (S5).
6) The desired information can be accessed step by step.

[0031] Then, the user selects the G11B and 00 5 among the International Patent Classification (IPC) code screen output to the treemap embodiment, further, from among 002, 003 and 004 is a sub-code 004 selecting, the search engine 42 program has a 004 said selected among the patent information data the search as a sub-code, i.e., selects only the patent information data belonging to the technical field of G 1 1B00 5/004 and, as shown in FIG. 1 0, item and patent number of solving problems and solutions as the classification fields that are included in each patent information data the selected is output sequentially on the screen in the search terminal PC Since the data is provided so that the user can solve the problem and the solution presented by the information from the patent information data belonging to the specific technical field. It can be accurately confirmed to be the desired information data to look at the contents of the unit item.

As described above, after checking the specific material data desired by the user through the summary information output on the screen or by the classification file (solving problem and solving means) item in FIG. When requested (S59),
Since the central processing unit 40 extracts only the requested specific information data from the searched information data and transmits the requested specific information data to the corresponding search terminal PC through the network interface 10, it is illustrated in FIGS. 18 and 19. When the user requests the enlargement of the screen, the central processing unit 40 of FIG.
The enlarged drawing data is provided as shown in FIG.

In the above embodiment, the above-described analysis process can be repeated for all the information data selected from the specific field or the specific year depending on the searched information data or the analysis conditions, but it is searched. If the number of information data is too large, request sampling after inputting and setting sampling conditions such as international patent classification code and year on the menu screen of patent analysis as shown in FIG. 9 ( S52), the search engine 42 program inputs the searched patent information data and preferentially samples it based on the set sampling condition (S54), and performs the analysis process only on the sampled information data. (S55), for example, the total search materials are 100 in 1981 and 2 in 1982.
50 cases ,. ． ． If there are 1221 cases in 1996, the user inputs “year classification” as the sampling condition and 5% as the sampling rate, and then requests the sampling of information data. patent document data corresponding to 5% or 5% increments each year, i.e., 198
5 for 1 year, 12 for 1982 ,. ． ．
61 cases are arbitrarily selected for 1996, and the above-described analysis process is performed only on the patent information data thus selected.

It is also possible to specify the sampling for each technical field together with the sampling by the above-mentioned year, and if the sampling is specified for each technical field in this way, it is arbitrarily 5% from each year. Instead of selecting each, the sample materials of the search materials will be selected from the search materials of the relevant year to be 5% by nuclear technology field.

[0038]

As described above, in the information retrieval method, the information automatic classification method, and the information analysis method according to the present invention, the problem to be solved and the solution means items are classified as a classification file to provide information data, Since the data is stored in a file format in cooperation with the material data search formula, the desired material can be accessed more easily, and the desired data can be stored without repetitive searches using the stored file. Since the information data can be obtained quickly, and the search result information data can be sampled, the analysis information data is significantly reduced, and thus the information data can be analyzed more quickly. It has the effect of being exposed.

Further, since the analysis result of the information data can be provided on the screen in various graphic forms such as a pie map, a tree map, a trend map and a bar map, the analysis result of the information data can be grasped. The effect is that it is extremely easy.
