DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A database system according to an embodiment of the present invention will be described below with reference to the accompanying drawings. In the description of each drawing, the same constituents will be referred to with the same numerals without repeating their overlapping descriptions. FIG. 1 shows a functional block diagram of a database system according to an embodiment of the present invention. This system includes display means 1 for displaying a text or an object, display control means 2 for controlling the display means 1 to display the text or an object, and the display means 1 for displaying the text or the object. In this case, the text or the object is stored together with the search instruction means 3 for designating the word displayed on the display means 1 to instruct the search, and the search table for searching the text or the object from the word. The stored storage means 4 and the search means 5 for searching the corresponding text or object from the storage means 4 in accordance with the instruction from the search instruction means 3 and transferring the searched text or object to the display control means 2 for display. To have.

The system also includes a target input means 6 for inputting a text or an object to be stored in the storage means 4, and a text or an object input from the target input means 6 based on a predetermined rule. And creating a search table for searching a text or an object from the extracted word, and storing the text or the object in the storage means 4
On the other hand, a registration / deletion means 7 for registering / deleting a word in the above-mentioned retrieval table when necessary is stored.

The storage means 4 stores a usefulness table in which usefulness information of texts corresponding to words is stored, and the usefulness table of the texts or objects retrieved by the retrieval means 5 and displayed on the display means 1 is stored. The detection means 5 includes an evaluation value input means 8 for inputting the evaluation of usefulness, and a changing means 9 for changing the contents of the usefulness table according to the evaluation value input from the evaluation value input means 8. Is configured to search for a text or an object according to the information of the usefulness table.

FIG. 4 shows a title table which is a search table for searching a text or an object from the above words. That is, the ID (identification information) assigned to a text or an object is associated with a word, such as a title representing the text or the object, such as "dog", "bird", "forest", ... A flag "1" is set in the area where the corresponding word is a title or the like and intersects with the text or the ID of the object. For example, it indicates that the text having the ID “003” or the title of the object is “dog” or “human”. In addition, in the storage means 4,
The text or the object itself is stored in association with the ID.

FIG. 5 shows the contents of the usefulness table. The usefulness table corresponds to words such as titles of IDs corresponding to texts or objects,
Its usefulness is stored. Therefore, when there are two or more words such as a title for a text or an object, usefulness information about each word is set. Further, in the initial state, the usefulness is set to "50".

The database according to the present invention may be a single computer system, but is constituted by, for example, a network system using LAN and WAN shown in FIG. 2, and texts or objects by clients 11-1 to 11-5. Is performed, a search instruction is input, an evaluation value is input, a text or an object is displayed, and the like. On the other hand, in the server 10, the function of the portion surrounded by the one-dot chain line in FIG. 1 is executed. In other words, it is a process of deleting registration of texts and the like in the storage means 4, changing the contents of the usefulness table, retrieving desired texts and the like from the storage means 4 and transferring them to the relevant client.

FIG. 3 shows the actual configuration of the client 11. That is, the client 11 is provided with a CPU 20 for centrally controlling the entire computer system, and a main storage device 21 in which programs and data used by the CPU 20 are stored. Furthermore, CPU
A keyboard controller 23, a display controller 24, a mouse controller 25, a printer controller 26, a magnetic disk controller 27, and a communication interface 28 are connected to a system bus 22 extending from 20. The keyboard control unit 23
Data is input to the CPU 20 by operating the keys of the connected keyboard input device 29. The display control unit 24 controls the connected CRT display device 30 to display data. The mouse control unit 25 supplies the CPU 21 with data from the mouse 31, which is a connected pointing device. The printer control unit 26 controls printing of the connected printer device 32. The magnetic disk control unit 27 performs data read / write control on the connected magnetic disk device 33 under the control of the CPU 20. A communication processing unit 34 is connected to the communication interface 28 to send data to a LAN or the like,
Also, data can be received from a LAN or the like.

The CRT display device 30 serves as the display unit 1, the display control unit 24 serves as the display control unit 2, the keyboard input device 29 or the mouse 31 serves as the search instruction unit 3,
They function as the target input means 6 and the evaluation value input means 8, respectively. In addition to the keyboard input device 29, when inputting text or the like stored in the magnetic disk of the magnetic disk device 33, the target input means 6 has a floppy disk drive, which is not shown in this embodiment. It also includes the case where a text or the like is input by a floppy disk. For a search instruction, an input of an evaluation value, a target input, and a display request of another candidate of text corresponding to a predetermined word, a predetermined command is input by the keyboard input device 29 or a mouse 31 is used. The configuration can be performed by clicking a predetermined icon or the like displayed on the CRT display device 30.

On the other hand, the actual configuration of the server 10 is similar to that of the client 11 shown in FIG. However, since it is not necessary to input a search instruction or the like in the server 10, the keyboard input device 2
9, CRT display device 30, mouse 31, printer device 3
2 and these control units are not necessarily essential components. In addition, the title table shown in FIG. 4 and the usefulness table shown in FIG.
Is provided in the magnetic disk device 33, and the text is stored in the magnetic disk device 33 in correspondence with the ID.

FIG. 6 shows a flowchart corresponding to a program stored in the main storage device 21 of the server 10 and executed by the CPU 20 when registering a text or an object (hereinafter, represented by text). . The CPU 20 of the server 10 detects whether or not a registration instruction has been issued from the client 11 (S4).
1). On the client 11 (or server 10) side, the text to be registered is loaded into the main storage device 21,
A registration instruction is input by displaying it on the CRT display device 30, and a text together with this registration instruction is sent from the communication interface 28 to the server 10. Server 10 is LAN
When a registration instruction comes from the communication interface 28 via the communication interface 28, the text which is the target data is fetched via the LAN (S42). Next, the CPU 20 holds the captured text in the main storage device 21 and analyzes the title (S43). Furthermore, the title table shown in FIG. 4 is created using the titles (words) obtained by the title analysis, and the I set in the title table is set.
The text is registered in the magnetic disk storage device 33 in association with D (S44).

FIG. 7 shows the title analysis (S
43), a flow chart is shown in which the data (text) registration (S44) portion corresponding to the creation of the title table and the ID correspondence is more detailed. In other words, at the time of title analysis, a certain position in the text (or "title"
The title part is searched from the position of the character (S5) (S5)
1). For example, this is detected by using the first document of the incoming text as a title. In addition, the document is taken out by regarding a predetermined position as the title, such as using the last document as the title. Specifically, when the first document is used as the title, the first text is written as the text (TEXT) in FIG.
Since there is a document indicated by a line segment on the line, this is extracted. Next, the title part is decomposed into words (S52). For example, if "Japanese writing style" is detected as the title, it is decomposed into the words "Japanese" and "writing style". Next, an ID is added to the text, the ID is associated with each word obtained by decomposing the title, and registration is performed in the title table as shown in FIG. 4 (S53). Further, the ID assigned to the text and the text are stored in association with each other (S54).

FIG. 8 shows a title extracting process which is executed instead of steps S51 and S52 in the flowchart of FIG. That is, at the time of title analysis, instead of searching for a title part from a predetermined position in the text as in FIG. 7 (S51), sentences in the text are extracted one after another (S55), and each extracted sentence is extracted. The subject is extracted (S56). Here, as a method of extracting the subject, a known method such as dividing a sentence into phrases and extracting a word or the like with a case particle from a noun or the like is adopted. The process after extracting the word (title) in this way is performed in step S of FIG.
53, S54.

According to the method of FIG. 8 described above, the number of words in the title becomes too large, and the possibility of including inappropriate words increases. For example, as in the text shown in FIG. 10, in “Shiba Inu is a Japanese dog having the characteristics of XXX ...”, “Shiba Inu” is extracted as the title, but in the text shown in FIG. Is extracted from the first sentence as the title, "Japanese dog", but from the sentence at the bottom, it is the subject "Shiba Inu".
Is extracted, which results in the extraction of words that are not suitable as titles. Therefore, the title is extracted as shown in FIG. 9 in consideration of the predicate.

First, a sentence is extracted from the beginning of the text (S61). The subject of the extracted sentence is extracted (S62).
This extraction method is performed using a known Japanese analysis technique, as in the case of FIG. Next, the predicate of the same sentence is extracted (S6).
3). The detection of the predicate here is also performed by a known Japanese analysis technique, for example, a noun accompanied by a verb is extracted. When the subject and the predicate are extracted for one sentence, it is detected whether the subject and the predicate have a certain relation, for example, whether the subject has a higher / lower relation in the thesaurus (thesaurus) (S64). If there is no fixed relationship,
Without registration in the title table, on the other hand, if there is a certain relationship, the extracted subject and text I
The title table is stored in association with D (S6).
5). Then, it is detected whether or not the above process is completed for all the sentences in the text (S66), and if not completed, the process returns to step S61 to perform the process. When the process for all the sentences is completed, the ID and the text Are registered in association with each other (S67).

According to the processing method of FIG. 9, since the subject "Shiba Inu" and the predicate "Japanese dog" have a higher / lower relationship in the first sentence of the text of FIG. “Shiba Inu” is extracted as the title. On the other hand, in the first sentence of the text in FIG. 11, the subject “Japanese dog” and the predicates “Akita dog” and “Shiba inu” have a high-rank / low-rank relationship, so the subject “Shiba inu” is the title In the final sentence "Shiba Inu is taking a walk", there is no upper / lower relationship between the subject "Shiba Inu" and the predicate "Walk", so the subject "Shiba Inu" is It is not extracted as a title and is not registered in the title table. Thus, it can be seen that only the appropriate titles will be extracted. On the other hand, as shown in FIG. 12, in the case of detecting the title of the text having the title portion, it is appropriate to register the word in the title table by the processing according to the flowchart shown in FIG. Therefore, at first, when the usefulness of the usefulness table falls below the predetermined threshold value by performing the processing by one of the methods and registering it in the title table in the subsequent operation, the title table of another method is used. Change the content. The usefulness table shown in FIG. 5 is registered (initial value = 50) at the time of registration in the title table.

FIG. 13 shows the processing of the server 10 corresponding to the text search instruction. That is, FIG.
The CPU 20 of the server 10 performs processing by the program corresponding to the flowchart shown in FIG. That is, CPU
20 monitors whether a search instruction comes from the client 11 (S71). At this time, the client 11
, The text is displayed on the CRT display device 30 as shown in, for example, TEXT of FIG. 14, and when the mouse 31 gives an instruction as shown in M1 (or M2), the text is searched along with the word. The search instruction is transferred to the server 10 via the LAN and WAN. Upon detecting this, the CPU 20 of the server receives the instruction word in the text displayed on the client and detects it (S72), and searches the title table shown in FIG. 4 for the ID of the text corresponding to this word. (S7
3) Further, based on this ID, the text stored corresponding to the ID is searched (S74).

In FIG. 14, when a word of text (TEXT) is designated by the mouse 31 as shown by M1 and M2,
The title table is searched to obtain the ID, the text A is searched from the word shown in M1, and the text B is searched from the word shown in M2. The retrieved text is LA-coded from the server 10 to the corresponding client.
The data is transferred via N and WAN and is used for display on the CRT display device 30 (S75). As described above, in the system according to the present embodiment, the next text is displayed by designating the desired word in the text displayed on the CRT display device 30, and the desired word in the displayed text is displayed. By instructing, the next text is displayed, and the necessary text (information) can be obtained by subtracting between the texts, which is extremely convenient. When two or more IDs are associated with a word, the usefulness table (FIG. 5) is referred to and the text having the highest usefulness is transferred from the corresponding plurality of texts. Then, when the display request for the next candidate is sent, the CPU 20 of the server 10 extracts and transfers the text having the next highest degree of usefulness.

FIG. 15 shows the processing of the server 10 corresponding to the sending of the evaluation of the usefulness of the text searched and displayed for the search instruction. That is, the CPU 20 of the server 10 performs processing by the program corresponding to the flowchart shown in FIG. Before this, the text is displayed according to the search instruction on the client side, and the evaluation value of the usefulness of this displayed text (whether it was useful or usefulness is expressed in about 5 levels) ) Is keyed in, and the information indicating that the evaluation value is to be transmitted is transferred to the server 10 together with the evaluation value. At this time, the CPU 20 of the server 10 is waiting for the arrival of the evaluation value (S81). When the evaluation value arrives, the CPU
20 fetches this and changes the usefulness table (S82). For example, whether the evaluation value was useful (Y
In the embodiment in which the usefulness information is input, the usefulness information of the usefulness table is increased by, for example, “10”, and the usefulness information of the usefulness table is useful if there is an input of not useful (NO). Degree information, for example, "10"
Lower it. Further, in the embodiment in which the usefulness is input in five levels, “3” is changed to “0”, and “5” is adjusted up and down. That is, when the usefulness is "1", the usefulness information in the usefulness table is decreased by "10", and the usefulness is "5".
Then, the usefulness information of the usefulness table is increased by "10". Also, if there is a request for the next candidate text for the transferred text, for example, the usefulness is decreased by "5".

As described above, after the usefulness table is changed in step S82, it is detected whether the usefulness of the change is equal to or less than a predetermined threshold value (eg, 30) (S83). If it is not less than the threshold value, the process is terminated, while if it is less than the threshold value, the title table is changed and the corresponding usefulness information in the usefulness table is changed (preset to 50) ( S8
4). That is, the content of the title table is changed for the text whose usefulness is equal to or less than the threshold value by another method different from the method in which the word in the current title table is extracted. For example, when the word in the current title table is extracted by the method of FIG. 7, processing such as re-extracting by the method of FIG. 9 is performed, and the contents of the usefulness table are changed to newly extract the word. The usefulness corresponding to is set to "50".

Thus, with the above configuration, when the text retrieved from a given word is often inappropriate,
The extraction of the title (word) of the text is performed again and by a method different from the previous one, so that the text retrieved from the predetermined word can be made useful.

Although the text is registered from the client in the above embodiments, the text can be registered from the server 10 in the embodiment in which the server 10 is provided with the input means. Further, in the embodiment in which the server 10 has the client function, the text can be searched and displayed.

[0035]

As described above, according to the database system of the first aspect, when a text or an object is displayed and the displayed word is designated and a search is instructed, this instruction is displayed. Accordingly, the corresponding text or object is searched, transferred, and provided for display. Therefore, by specifying a word in the displayed text or object, the next text or object, and the next text or object are displayed. It is convenient because you can pull texts or objects one after another.

As described above, according to the database system of the second aspect, when a text or an object is input, a word is extracted from the input text or the object based on a predetermined rule, and this extraction is performed. It is easy to create a table for searching text or objects from stored words, remember the text or objects, and delete words in the table for searching when needed, without the need for humans to set link information between the text and objects. It is possible to create a database linked to.

As described above, according to the database system of the third aspect, when the evaluation of the usefulness of the retrieved text or object is input, the content of the usefulness table is correspondingly input. Since the text or object is searched according to the information in the usefulness table as the change is made, it is possible to improve the probability that the text or object is an appropriate text or object when the word is specified and the text is extracted. Is.

As described above, according to the database system of the fourth aspect, when the usefulness information in the usefulness table is equal to or less than a predetermined threshold value, the corresponding text or object is word-based based on another predetermined rule. And create a lookup table to search for text or objects from this extracted word, so
It is preferable because learning is performed so that appropriate texts or objects can be drawn out.
