Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an information search terminal device.

(Prior Art) A typical example of a conventional information retrieval terminal device is the V? +壬11. For example, C
When searching for information, the terminal device of the APTAIN system displays information prompting the user to input search items (hereinafter referred to as item input request information), as shown in FIG. Therefore, the user operates the key-powered device attached to the terminal device according to the displayed information, and selects the desired item by keying in the character string that corresponds to the desired item (hereinafter referred to as the search item character string). (Hereinafter, the operation of selecting this item will be referred to as item input). This search item character string is transmitted by the terminal device to the center having the database. The center receives this search item character string, sends the corresponding information to the terminal device, and displays it on the terminal device. For example, in Figure 3, if you want the search item "News J," if you enter the search item character string rl#J, the corresponding information will be displayed as shown in Figure 4. In the CAPTAIN system, By repeating this key-in item input operation, the information desired by the user can be obtained.

Here, if the item input for the item input request information is
If the user misunderstands the selection of an item and inputs it, or inputs the wrong keystroke and selects a different item than the intended item, to correct the error, press the function key called [Backward]. I am dealing with it. The "reverse" function is a function that redisplays previously searched information in accordance with the history of the search process stored at the center.By using this function, users can Possible item input request information can be searched and the item input can be performed again. For example, as shown in FIG. 5, users A, B, bl, b2. C, cl, c2. Assume that the search is performed in the order of D and di. Here, A, B, C, D are item input request information, and bl, b2. cl, c2. d
Let i be information that does not require item input. If a search error is noticed in the information of dl, the information of D is redisplayed by using the "backward" function. If the item input error was on an earlier screen, for example C,
Similarly c2. Use the "backward" function to redisplay cl and C in that order,
All you have to do is input the appropriate items when C is displayed.

Additionally, as an extension of this "backward" function, some terminals have a function called "reselection." While the conventional [reverse 1 function retracts the history of all displayed information, this function retracts the history of only item input request information, skips information unrelated to item input, and retracts the history. In the example shown in Fig. 5, the history for "reselection" is as shown in Fig. 6, and when the [reselection] function is requested in dl in Fig. 5, the information of D is displayed, and if you request "reselection", cl and c2 are skipped and C is displayed.

In addition to this, the CAPTAIN system has a direct search function. This is because each piece of information has a unique number called an information search number (or page number), and by entering this information search number after pressing the "*" key from the terminal,
Finally, if you press the "#" key, the information corresponding to that number will be displayed. For example, in the example in Figure 3, r
000010000J is the information search number, and if you enter r*oo0010000#J from the terminal, the information in Figure 3 will be displayed even if you are searching for any other information.

In this way, in an information retrieval system, when searching for information, the user is requested to select the information displayed on the terminal device, and the user returns a response to the request.The input operations in this case are summarized below. (called response input), proceed with the process interactively, or search directly using the information search number you know in advance, and correct search errors using function keys as necessary. There is.

(Problems to be Solved by the Invention) However, in an actual information system, since a wide variety of information is provided, the functions as in the above example may not be sufficient for searching work.

For example, suppose that information is displayed as shown in FIG. 7 by a user's search. Here, A, B.

C, D are item input request information, and bl, b2. cl,
c2. It is assumed that di, d2 and d3 are information that does not require item input. In this example, 1↓ -14-16-tnAJ+t!
ff1l! T'xl-1% l --f l to 〒'3
CI M -kl 144↓This is the final information to be deleted, and D is always displayed after each piece of information is displayed. In this case, the history of the "backward" function is as shown in Figure 7, and the history of item input request information for "reselection" on a terminal with the "reselection" function is as shown in Figure 8.
The result is as shown in the figure.

Here, if you make a mistake in inputting an item for the item input request information as in the above example, in order to correct the error, use the backward 1 function to go backwards through the previously searched information according to the history of the search process and display it again. Assume that you are searching for item input request information that is considered to be incorrect. Assuming that the information of d3 in FIG. 7 is currently displayed, and the item input request information that requires input correction is C, by the time C is displayed, D, d2°D, di, c2 . Seven screens of cl are displayed. Furthermore, if a terminal with a "reselection" function is used to perform a similar operation using the "reselection" function, D, D, D, and D will be displayed three times before C is displayed. In this way, in the example in Figure 7, D is displayed three times even though it backtracks to C. In this way, when correcting item input,
If the function simply memorizes the history and backs up the history, the same information may be displayed repeatedly, so it is difficult to search for item input request information that actually requires correction. This takes time and reduces search efficiency. Additionally, [in the Reverse 4 function, there is generally a limit to the history storage capacity of the center (10 in the CAPTAIN system).
(up to the screen), there was a limit to the amount of information that could be redisplayed using the Backward 1 function, and in the worst case scenario, there was a drawback that the entire search would have to be restarted from the beginning.

Such drawbacks are one of the causes of heavy time and mental burden on users and increased fatigue during information retrieval work.

An object of the present invention is to store history in a hierarchical manner for each item input request information, thereby making it possible to eliminate duplicate display of information when reversing as described above, and improving search efficiency in error correction work. An object of the present invention is to provide an information retrieval terminal device that allows users to search for information.

(Means for Solving the Problems) The information search terminal device of the present invention includes information search number detection means for detecting an information search number of display information, and information search number detection means for detecting the information search number detected by the information search number detection means. A history hierarchy storage means for storing history in a hierarchical manner; a function selection input means for selectively inputting a function requested by a user; and a function selection input means for selecting and inputting a function requested by the user; and history selection means for selecting an information search number.

(Operation) In order to overcome the above-mentioned drawbacks, the present invention stores the history of item input request information in a hierarchical manner. For example, the fifth
If you search as shown in the figure, the history of item input request information will be as shown in Figure 6, but instead of simply storing A, B, C, and D in the order, B to lower
However, A is stored above B. Similarly,
B and C, and C and D also remember their mutual relationships. Therefore, the seventh
If you search as shown in the figure, even if D is searched many times,
Since the relationship between C and D is stored when D is first searched, the history becomes as shown in FIG. 6, and D is not added to the history as shown in FIG. 8. Further, suppose that information on C is displayed as the search continues. Therefore, if another item is selected in C and the information in E is newly displayed, the history will be as shown in FIG. 9. In other words, hierarchically, D and E exist below the information of C,
It is determined that E is the latest history from C to lower-level information, and D is the oldest history.

Hierarchizing the history in this way prevents history from being duplicated. The basic operation of the present invention will be explained below.

In the information search terminal device of the present invention, when displaying the information received from the center on the display screen, the information search number detection means extracts and saves the information search number unique to the information from the received information. When the user inputs a response, the information search number detection means determines whether the input character string is an item input for item input request information or not. Only in this case, the held information search number is detected as the information search number of the item input request information. This detected information search number is
The history hierarchical storage means stores the historical data in a hierarchical manner.

If the user makes a mistake in the search process and wants to re-display the item input request information in the upper layer or the item input request information in the lower layer of the currently displayed information in order to retry the search, The desired function is input using the function selection input means. The input requested function is transmitted to the history selection means, and an information search number of item input request information corresponding to the requested function is selected from the stored contents of the history hierarchical storage means, and is treated as an input for direct search. .

In this way, it is possible to store the history in a hierarchical manner for each item input request information, and by moving backward and forward through the hierarchy, it is possible to eliminate duplicate display of information when backward. .

(Example) FIG. 1 is a diagram showing the basic configuration of the present invention.

The information received by the communication control means 1 is sent to the terminal control means 2.
The image is decoded by the drawing/display means 3 and displayed on the display device 4. At the same time, the information search number detection means 5 selects and holds the information search number of the displayed information from the displayed information.

Further, characters inputted by the user using the key input device 9 are transmitted by the communication control means 1 via the terminal control means 2. Here, when the user inputs some kind of response according to the information displayed on the display device 4, the information search number detection means 5 determines whether the response input is for item input request information, and inputs the item. Only when it is determined that the item input is for request information, the stored information search number is detected as the corresponding information is item input request information. The detected information search number is checked by the history hierarchy storage means 6 for its relationship with the information search number of other item input request information previously searched by the user.
After the mutual hierarchical relationship is determined, the information is stored together with the information search number of the item input request information in the upper layer and the information search number of the item input request information in the lower layer. By repeating the above operations, the history of item input request information is stored in the history hierarchy storage means 6 in a hierarchical manner according to the information searched by the user.

If the user makes a mistake in the search process and wants to re-display the item input request information in the upper layer or the item input request information in the lower layer of the currently displayed information in order to retry the search, The desired function is input using the function selection input means 7. The input requested function is transmitted to the history selection means 8, and the information search number of the item input request information corresponding to the requested function is selected from the stored contents of the history hierarchy storage means 6, and is input as the information search number request input. It is transmitted by the communication control means 1 via the terminal control means 2.

FIG. 2 is a diagram showing an example in which the present invention is embodied as a terminal device of the above-mentioned CAPTAIN system.

In FIG. 2, 20 is a microprocessor that interfaces with peripheral devices via a bus. 21 is a read-only memory (ROM);
A control program for the microprocessor 20 is stored. A random access memory (RAM) 22 is used as a data memory for the microprocessor 20.

23 is video display dedicated arbitrary access memory (VRAM)
and display data is stored. A display device 24 displays a video signal. A graphic display controller (GDC) 25 stores display data in the VRAM 23, converts the data in the VRAM 23 into a video signal, and outputs the video signal to the display device 24. 26 is a modulation/demodulator (MODEM) for the communication line, which modulates and demodulates data signals on the communication line. A communication control processor (ccp) 27 provides an interface between the MODEM 26 and the microprocessor 20. 28
is a keyboard for inputting characters and control keys. 29 is a keyboard interface (KIF),
It provides an interface between the keyboard 28 and the microprocessor 20. Note that the keyboard 28 has functions such as "re-select" (backwards the history of item input request information), "already selected" (backwards the history of item input request information) and (backwards the history of item input request information) Enter to move forward to the information side To execute the function of "old selection" (advance the history of item input request information to the side of item input request information that is one older than the latest one in the lower hierarchy), press -. Each function key for input is added.Hereinafter, the contents of the present invention will be explained in the second section.
This will be explained in detail according to the diagram.

The information search terminal device according to the present invention has two functions: a function of displaying received image information and a function of transmitting input character information. Therefore, first, the function of displaying received image information will be explained.

The microprocessor 20 inputs the image information received by the MODEM 26 via the CCP 27 according to the control program stored in the ROM 21, and inputs the image information received by the MODEM 26 to the GDC 25.
Output commands to draw and display. At the same time, an information search number for display information is selected from the received information.

Next, the function of transmitting input character information will be explained.

When the user inputs characters using the keyboard 28,
The microprocessor 20 converts the input characters into the KIF 29 according to the control program stored in the ROM 21.
read via MODEM26 via CCP27
Send by. At this time, when the user inputs some kind of response according to the displayed information, the microprocessor 20 determines whether or not this response input corresponds to the item input request information according to the control program stored in the ROM 21. Make a judgment. This judgment is made because the item input for item input request information is generally a character string consisting of alphanumeric characters or kana characters, followed by the "#" key, so the first character string entered is an alphanumeric character. Alternatively, it is determined whether it is a kana character and there is a "#" sign at the end. Then, only when it is determined that the item input is for the item input request information, the information search number selected in advance is detected as the information corresponding to the number is the item input request information. This information retrieval number is stored in RAM 22 by microprocessor 20 in accordance with a control program stored in ROM 21. This storage operation will be explained below using FIG. 10. FIG. 10(a) is a diagram showing the structure of a history block in this embodiment. In the present invention, the history block is a basic element constituting the history of item input request information, and as shown in FIG. 10(a), it includes an information number storage area, an upper layer information number storage area, and a lower layer information number storage An array (assumed to have two elements in this embodiment). Therefore, first, we investigate the relationship with the history block of other information search numbers previously searched by the user stored in the RAM 22, check whether the same information search number has been searched before, and Only when the same information search number has not been searched, a history block area is reserved in the RAM 22 as a new information search number, and the information search number of the information searched immediately before is used as the upper layer information search number and the upper layer information number. In addition, the lower layer information search number is stored as a blank in the lower layer information search number storage array.

At the same time, the 0th element of the lower layer information search number storage array of the history block corresponding to the information search number searched immediately before is stored with the lower layer information search number only if the current content and the information search number are different. The contents of the 0th element of the storage array are moved to the 1st element, and the information retrieval number is stored in the 0th element.

By repeating the above operations, the history of item input request information is stored in the RAM 22 in a hierarchical manner according to the information searched by the user. For example, the history illustrated in FIG. 9 is configured as shown in FIG. 10(b). in this way,
Each history block uniquely corresponding to the item input request information is created, and the contents of each history block indicate a hierarchical relationship with other history blocks, and the history of the item manual request information is hierarchically created by these history blocks. has been done.

Next, if you select an item for the item input request information that is different from the intended item due to a misunderstanding or input error, and you want to correct the error later. Commentary 1 The function of the function keys of "old selection" will be described.Each function key is stored in the ROM by the microprocessor 20.
According to the control program stored in the KIF 21, the input function key signal is read through the KIF 29, and the function ``Reselection 1'' requests the display of the item input request information corresponding to the higher level of the currently displayed information. In order to do so, select the information search number from the B history block stored in the RAM 22, and directly search for the information where the "*" symbol is followed by the information search number and finally the "#" symbol. Create a string for. The "Already selected" function is used to request the display of the latest item input request information that is below the currently displayed item input request information.
Select the information search number from the history block stored in the RAM 22, and add the information search number after the "*" symbol.
Create a string to directly search for information, followed by the "#" sign at the end. The "old selection" function is used to request the display of item input request information that is one item older than the latest item among the item input request information that is lower than the currently displayed item input request information.
Select from the history blocks stored in , create a character string for directly searching for information, consisting of a "*" symbol followed by an information retrieval number, and finally a "#" symbol.

The character string created in this way is processed by the microprocessor 20.
CC according to the control program stored in OM21
The "reselection", "already selected", or "old selection" function is realized by being sent by the MODEM 26 via P27 and performing the same operation as when directly searching for the information of the information search number. .

(Effects of the Invention) As described above, it is possible to store history in a hierarchical manner for each item input request information, to move backward and forward through the history, and to eliminate duplicate display of information during backward movement. This improves search efficiency when making corrections when a user misunderstands the selection of an item when entering an item, or inputs an incorrect keystroke and selects an item that is not intended for the purpose. Accordingly, it is possible to provide an information retrieval terminal device that reduces the user's time and mental burden and alleviates fatigue caused by the burden.
