Abstract

PURPOSE:To reduce a total searching time by obtaining searched results extracted from a data base based on a set search condition through a communication line and setting the searched results as the search condition for reading information recorded in a disk shape recording medium, which an operator finally wants to get. CONSTITUTION:The searched results extracted from the data base 8 are supplied to a data reception means 10 through the communication line and demodulated to be transmitted to a central process means 11. The supplied searched results, which are transmitted to a display means 9 to be displayed, are stored in a searched result storage means 12 and at the same time transmitted to an information read means 13 so as to selectively read the information from the disk shape recording medium. The read information is supplied to the display means 9 through the central process means 11 to be sequentially displayed. Thus, the searched results become the search condition for a second order search for selectively reading desirable patent information from the disk shape recording medium and even if many patent numbers are transmitted through the communication line, the necessary time is made very short.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention enables access to a database in which a large amount of information is accumulated and shared by multiple users via a communication line, The present invention relates to an information retrieval device that can extract information matching search conditions from a large amount of searched information and obtain it online.

[Prior art] For example, a database storing patent information such as 11 patents, 11 utility models, designs, trademarks, INPADOC, etc. is connected to a public telephone line or dedicated communication line]
There is a special information retrieval device that can be accessed via a communication line and obtain desired search results online. By using this device, desired information can be manually retrieved from a remote location and in real time from a huge amount of 4'F revision information stored in the database, which is very convenient. Moreover, since the database is shared, it is of the same quality no matter which information retrieval device located in different places is used.
You can get search results for .

Also, CD-ROM (read-only memory using a compact disk) disk, magneto-optical disk.

WORM (WRITE 0NCE READ MAN
Y) There is a disk-shaped recording medium with a large storage capacity, such as a disk. These recording media can store thousands to tens of thousands of pieces of image information, such as still city pictures, and can be accessed randomly, allowing the necessary information tv to be quickly retrieved. Furthermore, since it is a disk-shaped recording medium, it can be easily removed from a reading device for reading information recorded on the disk-shaped recording medium, and has excellent portability. Therefore, it is easy to read out information from a different location.

[Problems to be Solved by the Invention] However, such an information retrieval device using a communication line has the following problems in terms of information transmission speed and amount of information.

In other words, in order to receive search results at a low data transmission speed such as 300 bps when using a general public telephone line VA and 4800 bps even when a dedicated communication line is specially provided, code information, image information, etc. There is an inconvenience that it takes a considerable amount of time when receiving a large amount of data consisting of information, and this inconvenience occurs when information retrieval is performed using an information retrieval device installed in a remote location. In addition, the inconvenience of requiring high communication costs may also occur.

In addition, the database used in this [1]
Normally, TSS (Time Sharing System) is adopted so that multiple users can share the service, and for this reason, there is a waiting time to receive the service, and from this point of view, it is difficult to receive a large amount of information. In some cases, the disadvantage was that it required considerable travel and communication costs.

In addition, focusing on the large capacity of disk-shaped recording media, information and search keywords extracted from this information are recorded together on disk-shaped recording media, and inputted from input means such as a keyboard when searching for information. It is possible to think of a method for reading out information to which a keyword matching the given keyword has been added from this disc-shaped recording medium, but if the information is distributed and recorded on multiple disc-shaped recording media, There is a drawback in that unless information is searched for each disk-shaped recording medium using the same keyword in the same way, it is not possible to know whether all the desired information has been picked up.

In other words, if the information necessary to perform a search is recorded in a distributed manner on each disc-shaped recording medium, the search must be performed on multiple disc-shaped recording media, which is essential. If there is, please feel free to
The completeness of the search may not be expected.

[Means for Solving the Problems] Therefore, in this invention, 1) an information search is carried out, for example, in patent information such as public gazettes and gazettes, product instruction manuals, service manuals, encyclopedias, etc. The purpose of this is to perform information retrieval targeting information for which there is a large amount of information that one ultimately wishes to obtain (generally, this information includes drawing information and is recorded in the form of image information, but there are exceptions). It is characterized in that a primary search result is obtained based on set search conditions, and a secondary search is further performed based on the obtained primary search result.

As a specific means, information reading means constituting the information retrieval device is used based on search results extracted from a database shared by a plurality of information retrieval devices based on search conditions and obtained via a communication line. An information read control signal is formed to read out the information that one ultimately wants to obtain, and this information read control signal is supplied to the information read means to control the information read position on the disk-shaped recording medium. (read-only memory using WRITE 0NCE READ) disk, magneto-optical disk,
In this method, desired information to be finally obtained from a disk-shaped recording medium such as a MANY disk is selectively read out by random access.

[Operation] Search results extracted from the database and received via the communication line are used as read control signals for selectively reading information recorded on the disk-shaped recording medium. Therefore, compared to the case where the information to be finally obtained is obtained via a communication line, the transmission cost is small. Therefore, even when using the communication 1'jjI line with a low transmission speed, search results can be obtained immediately, and the inconvenience of communication costs when installing an information retrieval device in a remote location is also eliminated.

Furthermore, the information you ultimately want to obtain can be randomly accessed from the disk-shaped recording medium of Daikan ¥ based on this search result.
Because it is searched and read out at high speed, a large amount of information such as drawing information can be obtained immediately, and it is also of high quality because it avoids information errors that are common when transmitting large amounts of information via communication lines. information.

Furthermore, although the information that one ultimately wants to obtain is read out from a disk-shaped recording medium, the information for searching, such as keywords, which forms the basis of that information, is centrally managed in a database shared by each information retrieval device. By accessing this database, it is possible to pick up all relevant information from all the information to be searched, and therefore there is no risk of omissions in the search.

Furthermore, since the information that one ultimately wants to obtain is read out from a disk-shaped recording medium, the information that should be stored in the database includes keywords and other information needed to search for desired information from a large amount of information. It can be reduced to only search information. Therefore, even when a large amount of information is searched, the amount of information stored is small and an economical database can be constructed.

[Embodiment] Hereinafter, an information search device for searching suitable patent information by applying the present invention will be described in detail as an embodiment with reference to the drawings.

The information retrieval device shown in FIG. 2 is a device for accessing a database storing a large amount of patent information via a communication line to obtain desired search results. It is equipped with an insertion slot 2.3, a keyboard 4, etc.

Next, its operation will be explained with reference to FIG.

(Transmission Mode) In the transmission mode, search conditions are set to obtain desired information from a large amount of patent information stored in the database, and the database is accessed via a communication line.

That is, a signal obtained by operating the input key 5 constituting the keyboard 4 is supplied to the search condition setting means 6. The search condition setting means 6 searches the database 8 based on this signal.
Set search conditions to search for desired patent information. Note that the search conditions to be sent to the database 8 may already be recorded on a data recording medium such as a floppy 7' disk or a RAM (random access memory), and the search conditions may be read from there. In this case, the floppy disk and RAM also constitute the search condition setting means 6. The search conditions set by the search condition setting means 6 are supplied to the data transmission means 7, converted into a signal format suitable for accessing the database 8 via the communication line, and sent to the communication line. Third communication line
It may be a line for which a user is paid a fee, or it may be a private line used within a company.

The database 8 side receives this signal and extracts information corresponding to the search conditions from a large amount of accumulated patent information. For example, if you want to search for patents with the keyword V modulation J out of a large amount of patent information stored in the database 8, use the entry key 5 and the search condition setting means 6 to search for the term modulation 1 or this term. The search code corresponding to is set as a search condition and sent to the database 8 via the communication line.The search condition set by the search condition setting means 6 is also displayed on the display means 9.
The information is also supplied to the CRT display l constituting the display means 9.

(Reception mode) Reception mode is a mode in which search results extracted from the database based on set search conditions are received via a communication line, and information readout control of the information readout means is performed based on the obtained search results. By doing so, the information recorded on the disc-shaped recording medium that is ultimately desired to be obtained is retrieved and read out. Further, the read information is sorted into only truly necessary information and then recorded on a disk-shaped recording medium by the read information recording means.

That is, the search results extracted from the database 8 are supplied to the data receiving means 10 via a communication line, demodulated, and then sent to the central processing means 11.

The central processing means 11 has a function of controlling the flow of data or processing data, and sends the supplied search results to the display means 9 for display, and also sends them to the search result storage means 12 for recording. Take seven sips.

As the search result storage means 12, for example, a data recording medium such as a RAM, a register, or a floppy disk is used. Note that when the information reading means 13 described later has an information recording function in addition to the information reading function,
Alternatively, if the readout information recording means 14, which will also be described later, has an information reading function in addition to the information recording function, these means can also be used as the search result storage means 12 and the search results can be stored in a disk-shaped recording medium. It can also be memorized.

The search results are stored in the search result storage means 12, and
Alternatively, after being stored here, it is read out and sent to the information reading means 13 via the central processing means 11.

The information reading means 13 is a CD-RO on which a large amount of patent information to be finally obtained corresponding to the search results is recorded.
Patent information is selectively read from a disk-shaped recording medium such as an M disk, a magneto-optical disk, or a write-once WORM disk, and the read patent information is stored in the central processing means 1.
1 to the display means 9 and sequentially displayed.

That is, the search results from the data receiving means IO are used in the information reading L stage 13 to form a read control signal for selectively reading desired patent information from a disk-shaped recording medium on which a large amount of patent information is recorded. be done. Looking at this from another perspective, this search result can also be taken as a search condition for a secondary search for selectively reading out desired patent information from a disk-shaped recording medium.

The information recorded on the disk-shaped recording medium includes, for example, the patent number, applicant, international classification (IPC), etc. provided for search, patent specifications corresponding to these search information, and this disk. Identification codes, patents, and utility models that are recorded on H4 state recording media.

Information indicating the type of public gazette, public notice, etc. and its correspondence with the income Q range is recorded. According to this, a patent number is recorded as search information on a disc-shaped recording medium, and these! When the patent specification corresponding to the 4'F patent number is recorded, the search result to be sent from the database 8 may be only the patent number, such as 5B-1234.

In short, it is sufficient if the search information necessary to search for desired patent information (patent specifications, etc.) from a large amount of patent information recorded on a disk-shaped recording medium can be obtained as a search result. Therefore, even if a large number of patent numbers are transmitted using one communication line, the time required for the transmission is very small.

In addition, this information retrieval device groups the search results sent from the database 8 in correspondence with the information recorded on each disk-shaped recording medium, thereby minimizing the amount of loading and unloading of disk-shaped recording media into this device. Care has been taken to ensure that For this purpose, correspondence information storage means 15 and search result editing means 16 are provided.

The correspondence information storage means 15 stores information indicating the correspondence between the identification code given to each disc-shaped recording medium and the patent information recorded on the medium. To give a specific example, the patent claims (80-1 to G
o-5000, etc.) and its type (publication, public notice, patent,
utility model, etc.) and the identification code given to the medium (#1
etc.) are stored. The correspondence information is stored in the correspondence information storage means 15 by operating the input key 5 and supplying the operation information via the central processing means 11. Alternatively, by inserting a disc-shaped recording medium into the disc insertion slot 2, it is set in the information reading means 13 and a predetermined input key is pressed.
By operating 5, the correspondence information +M recorded on the disk-shaped recording medium is read out, and is supplied to the correspondence information storage means 15 via the central processing means 11 and stored therein.

The search results output from the data receiving means 10 or the search results temporarily stored in the search result storage means 12 are read out and sent to the search result editing means 16 via the central processing means 11.
is supplied to The search result is, for example, information indicating a patent number and its type. When the search results are input, the search result editing means 18 refers to the correspondence information stored in the correspondence information storage means 15 and groups them in accordance with the patent information recorded on each disc-shaped recording medium. conduct. By this operation, the search results are arranged to read information for each identification code, that is, for each disk-shaped recording medium, and the trouble of repeatedly inserting the same disk-shaped recording medium into the disk insertion slot 2 is relieved. . This function allows the arrangement order of the search information included in the patent information recorded on the disk-shaped recording medium to be stored in the database 8.
This is effective when the order of search results differs from the one obtained from the search results.

Incidentally, as a search result, for example, a pair of information consisting of a patent number and an international patent classification (TPC) is received and stored in the search result storage means 12, and by operating the input key 5 etc., one of the pieces of information, the international Information reading means 1 sorts this pair of information based on the patent classification and reads out the patent number, which is the other information obtained by this processing.
3 and control the reading of the information, it is also possible to read out the patent information contained in the international patent classification from each disc-shaped recording medium.Of course, instead of the international patent classification, for example, the applicant, inventor, etc. It may be information of

The device also includes means (not shown) for selecting an identification code given to a disk-shaped recording medium from which information is to be read based on the received search results and the correspondence information stored in the correspondence information recorder tQ means 15. The identification code selected by the identification code selection means or information corresponding to this identification code is supplied to the display means 9 via the central processing means 11 and displayed on the CRT display 1. As a result, it is immediately known which disk-shaped storage medium should be inserted into the disk insertion slot 2 to read out information, and the work efficiency of information retrieval is improved.

Information reading control of the information reading means 13 is performed in response to the search results output from the data receiving means 10, and the information read from the disk-shaped storage medium is thereby read out via the central processing means 11 and read out from the information recording means. 14, and are sequentially recorded and stored on a write-once type 10RM disk inserted through the disk insertion slot 3, a magneto-optical disk that can be repeatedly recorded and reproduced, or the like. Note that if the disk-shaped storage medium from which information is read by the information reading means 13 is also capable of recording information, the read-out information recording means 14 can also record information on this disk-shaped storage medium. Alternatively, the information to be read by the information reading means 13 may be recorded in advance on the disc-shaped storage medium on which the information is recorded by the reading information recording means 14.

In this way, the information read out from the disc-shaped recording medium in response to the search results is sequentially recorded and saved on the same or other disc-shaped recording media, making it possible to immediately obtain the desired information next time. Become.

The readout information editing f2 stage 17 is provided to further narrow down the information read out by the information readout means 13 and then supply it to the readout information recording means 14. That is, the information read out in the +:Vt order from the first information reading stage 13 is supplied to the display means 9 via the central processing means 11, and its contents are displayed on the CRT display 1. The operator determines whether the displayed information is necessary or not by operating a predetermined input key 5 while looking at this display. This operation information of the human oyster 5 is supplied to the read information editing means 17 via the central processing means 11. When the readout information editing means 17 recognizes that the displayed information is worth saving based on this operation information, it reads out the information read out from the information readout means 13 and displayed on the display means 9 and outputs the information to the information recording means. 14, recording is performed on a disk-shaped recording medium. Further, when recognizing that the information is unnecessary, the information reading means 13 sends an information reading instruction signal to read the next information from the information reading means 13.
Send to. Through this operation, information narrowed down to what is truly necessary is stored on the disk-shaped recording medium.

The unreadable Ti information detection means 18 is provided to detect that information corresponding to the search result is not recorded on the disk-shaped recording medium. That is, the unreadable information detection stage 18 refers to the correspondence information regarding each disc-shaped recording medium stored in the correspondence information storage means 15, and detects disc-shaped recordings from the search results supplied via the central processing means 11. Search information corresponding to information that is not recorded on the medium and therefore cannot be read out is detected, and this detection result is supplied to the display means 9 and displayed on the CRT.
Display it on the display l. For example, it has a disk-shaped recording medium in which patent publications (patent information) of 1960 published patents 1 to 5000 and 5001 to 10000 are recorded, and database 8 to 1960 published patent publications 123
4.3760.6356.8098.12713 (search information), the unreadable information detection means 18 refers to the correspondence information tU stored in the correspondence information storage means 15. By doing this, 8

The display 1 displays a message such as "E".

Note that if alternative information for the information to be read from the disk-shaped recording medium is stored in the database 8 and it is possible to read this alternative information by setting a search condition in the search condition setting means 6, The above-mentioned surrogate information is obtained from the database 8 by operating a predetermined key 5 or by automatically supplying this detection result to the search condition setting means 6 via the central processing means 11. You can also do that.

By providing such a function, it is possible to easily distinguish between information that can be obtained from the disk-shaped recording medium and information that is not available according to the search results, and information that is not available can also be obtained from the database 8. It becomes possible.

[Effects of the Invention] According to the present invention, search results extracted from a database based on search conditions set by the search condition setting means are obtained via a communication line, and the search results are recorded on a disk-shaped recording medium. This is used as a search condition to retrieve the information that you ultimately want to obtain. Therefore, the information contained in the search results
[JQ only requires a small amount and can be obtained instantly even using a communication line with a low transmission speed. In addition, random access can be used to read out the desired information from the disk-shaped recording medium using the search results as search conditions, and the data transmission speed is so high that it is incomparable to the transmission speed of communication lines. You can get the information you want instantly.

In other words, this information retrieval device shortens the data transmission time by keeping the amount of information sent from the database low in response to the low data transmission speed of the communication line, and ultimately the information that needs to be obtained is sent out from the database. The total search time for obtaining the required information can be shortened because the data is read from a disk-shaped recording medium that has excellent random access and a high data transmission speed in response to search results.
