Description

[Detailed description of the invention] The present invention relates to an information retrieval device.

With conventional information retrieval devices that handle text information, such as electronic English learning machines and electronic dictionaries, when using them, you select a certain level in advance and perform a series of studies along that level, or within the range of that level. In order to look up words, moving to a different level meant going back to the initial level settings and starting over. For this reason, it is difficult to move to a different level of difficulty during learning, and it is also inconvenient when looking up words with different frequency levels.

The present invention has been made in view of the above points, and
Each piece of information is stored in association with a search word and level, and a means for selecting the level, such as a level key, is provided, and by selecting the level, the desired level can be set for each input search word. An object of the present invention is to provide an information retrieval device that allows easy retrieval of information.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an electronic English dictionary, and the process of converting English into Japanese will be described in detail. Code information corresponding to characters typed in from the normal alphanumeric keys 4 on the keyboard 5 is sequentially sent to the CPU 6. The CPU 6 assembles the sent character codes into words and uses them as search words in a fixed memory 7 (hereinafter referred to as
(referred to as EROM). The structure of the EROM7 consists of an English spelling part A and a jump code part B, as shown in FIG. 2 [I]. Now, taking the word Book as an example, the content of the jump code part B corresponding to "Book" in the spelling part A of EROM is "2892", and this value is the Japanese translation shown in Figure 2 [ ]. In the Japanese translation section C of the fixed memory 8 (hereinafter referred to as JROM) that stores , the translated word hon is stored at address 2892 in JROM. CPU6 has this value “2892”
You can use this to find the translated word "hon" that corresponds to "Book" in JROM. In the level code section D provided in the JROM, level codes 0 to 3 are preset and assigned to each Japanese translation word. Level codes 1, 2, and 3 are level keys 1, 2, and 3 on the keyboard 5, respectively.
0 corresponds to the selection of , and 0 corresponds to other cases, that is, the initial state of the device or the case where level keys 1, 2, and 3 are canceled by some method.
Now, assuming that level key 2 is pressed, the translated word hon has a level code of 1 added to it, so it does not match level key 2. When CPU6 determines this, the jump code part E of JROM
Memory address JAD where the next translated word is stored
It becomes possible to read out the value "05047" and use this to extract the translated word "Yoyakusuru".
The CPU 6 determines that the level code 2 added to "Yoyakusuru" matches the pressed level key 2, and displays the Japanese translation word "Yoyakusuru" corresponding to "Book" on the display section 9. Figure 2 []
In the jump code part E of JROM, the fact that the fifth digit is 0 means that there is another translation.
This indicates that it exists on JROM, and the following four-digit number indicates the memory address on JROM where the next translated word is stored. Also, the 5th digit is 1
indicates that this is the last translated word, and the following four digits indicate the equivalent of this translated word in English.
Points to a memory address on EROM. In this way, one English word and multiple corresponding Japanese translations are stored in EROM and JROM in a chain structure.

Further, in order to clarify the control flow of this embodiment, it will be explained with reference to the flowchart of FIG.
When the level key 2 is pressed in step S1 and "Book" is input from the alphanumeric key 4, the EROM read address EAD is set to 0 in step S2. At step S3, add 1 EAD and step
In S4, the contents of the spell section A (English spelling) at the read address of the EROM pointed to by the EAD are compared with the spell Book input from the key 4. If the comparison results in an unmatch (connector N), the process returns to step S3 and the contents of the next read address are compared. This process is repeated, and when the comparison is satisfied in step S4 (connector Y), in step S5, the contents of the jump code part B (Japanese translation) of the read address pointed to by the EAD are stored in the read address JAD of the JROM. store address). In step S6, the level code part D of the read address pointed to by the JAD is
The content (level code) is compared with the input of the level key 2. If the comparison does not match (connector N), go to step S7 and JAD the contents of JAD.
The contents of the jump code section E at the read address pointed to by (the address where the next translated word is stored) are replaced.
In step S8, it is determined whether the fifth digit of the replaced JAD is 0 or 1. If it is 0 (connector N), the process returns to step S6 and the level code of the next translated word is determined. This process is repeated, and when the comparison is satisfied (connector Y) in step S6, the contents of the Japanese translation section C at the read address pointed to by JAD are displayed in the display register (step S9).
Store and display this. Also, if there is no translated word corresponding to the pressed level key 2 on the JROM, it is determined in step S8 that the fifth digit of JAD is 1 (connector Y), and the process is executed in step S10.
There will be no corresponding level.

In this example, the level code was set to 0 to 3, but
By increasing the number of codes, you can make the level classification as detailed as you like. It is also possible to make n level keys correspond to n level codes, or to indicate the level by a single key for indicating the level or by the number of presses of the level up and down keys.
Furthermore, it is also conceivable to give an instruction using a combination of a function key and a normal alphanumeric key.

In addition, in the above embodiment, items that match the specified level are selected and displayed, but conversely, only items at the specified level may be masked and not displayed, or all items below or above the specified level may be displayed. It is also possible to

Furthermore, if multiple level codes are added to character information as in the above example for one Japanese translation word on the JROM, the same translated word can be displayed in response to instructions from different level keys. It can also be done.

Furthermore, in information retrieval devices such as electronic dictionaries that handle a large amount of text information, when searching for multiple levels, such as above or below a certain level, the searched information is searched for each level. By dividing and displaying the information, it can be made easier to use.

As explained above, according to the present invention, it is possible to easily search for information that meets the target level for each search word. In particular, when the present invention is applied to a learning device, it is possible to obtain appropriate translations, meanings, explanations, etc. according to the learning level from a large amount of information for input search words. Also,
Effects such as being able to easily shift to learning at a different level of difficulty at a desired point in learning can be obtained.
