Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a document editing method that can effectively edit a document by estimating the editing action intended by ambiguous editing instruction information input to document information. Regarding equipment.

[Technical background of the invention and its problems]

In recent years, with the development and spread of artificial intelligence and knowledge engineering, various information processing systems incorporating these techniques have been developed. For example, it is being considered to introduce inference, which is one of the important concepts of artificial intelligence, to construct a document editing system that creates and edits documents, programs, data, etc.

By the way, the above reasoning is based on general rules (e.g. axioms)
deductive reasoning that derives individual facts (e.g. theorems) from
Contrary to this deductive reasoning, it can be broadly divided into inductive reasoning, which derives general rules that hold between a set of facts (e.g., empirical knowledge) (e.g., general knowledge).

However, in a document editing system (editor) that has introduced deductive reasoning, for example, ``There is an error in this sentence.'' ” If the instruction “delete” is entered for a sentence without specifying the range of deletion, inferences such as (there is a grammatical error) → (the incorrect part will be subject to proofreading), etc. Use rules to infer the part to be deleted and say, ``This sentence contains an error.'' ” It becomes possible to obtain the following sentence. In other words, according to the inference rules of the system, it is possible to infer the editing action originally intended by the information from editing instruction information that includes ambiguity, and to execute this.

However, the above-mentioned [delete] instruction may be intended to delete only a specific character indicated by a cursor, etc., or may be intended to delete the entire sentence, or even delete an underlined character in the sentence. It may also be intended to be deleted. Therefore, there is a possibility that the document editing will be executed in a manner different from the original intention.

On the other hand, when creating the document ``Weather in various places'' shown in Figure 5b from the document ``Temperature in various places'' shown in Figure 5a, the editor that has introduced inductive reasoning will:
For example, from the two corrections Sapporo 25.5 21.4 cloudy → Sapporo: cloudy Tokyo 28.9 24.0 cloudy → Tokyo: cloudy, we can create a pattern conversion rule of <place name><real number 1><real number 2><weather> → <place name>: <weather> Inductive reasoning is performed, and according to the result of this inference, it is possible to correct the pattern ``Osaka 33.2 24.5 clear'' that appears next to ``Osaka: Clear'' automatically or with the operator's confirmation. .

By the way, in general, a lot of information is required to perform inductive reasoning reliably. However, if we try to provide a large amount of information necessary to perform inductive reasoning reliably, most of the document editing work may be completed, and the point of introducing inductive reasoning is lost. There is a risk of being lost. For this reason, in general, inductively inferred rules often contain a number of ambiguities, and the probability that the intent for editing a document will be correctly executed is lower than in the system that uses deductive reasoning described above.

In this way, a document editing system that incorporates inference greatly contributes to improving usability in a certain sense, but if the inference is incorrectly made, it can actually reduce usability. It has a problem that it invites.

[Purpose of the invention]

The present invention was made in consideration of these circumstances, and its purpose is to effectively introduce inference and enable efficient document editing without deteriorating usability. The object of the present invention is to provide a highly practical document editing device.

[Summary of the invention]

The document editing device according to the present invention includes, in editing instruction information for instructing an editing act to document information, a plurality of parameters indicating various attributes of a character string that is a target of an editing act instructed by the editing instruction information. and a rule storage means that stores rules indicating the relationship between each of these parameters and the editing action corresponding to the parameter, and the editing instruction information actually input for the document information to be edited. a selection means for setting any one parameter out of a plurality of parameters and selecting an editing action corresponding to the parameter by referring to a rule stored in the rule storage means; and an edit selected by the selection means. for inputting information indicating an editing means for performing an action on the document information to be edited, and whether the editing action performed by the editing means matches or does not match the editing action intended by the editing instruction information; an input means, and when the information indicating the discrepancy is input by the input means, another one of the plurality of parameters corresponding to the editing instruction information actually input to the selection means is updated and set. The present invention is characterized by comprising a control means for repeatedly selecting an editing action by the selection means and executing the editing action by the editing means.

〔Effect of the invention〕

Thus, according to the present invention, even if the input editing instruction information is ambiguous, the document editing action is inferred from the editing instruction information and the document editing is executed.
It becomes possible to improve its usability. Furthermore, even if the document editing action performed on behalf of the device is different from the intention of the device user, the inference process can be performed again from the input editing instruction information based on a simple instruction to obtain a different inference result (document editing action). This is done without compromising its usability.

Furthermore, since the inference system does not require advanced inference ability, the system can be easily constructed by simply preparing simple inference rules.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of the embodiment apparatus, and FIG. 2 shows an example of the flow of the inference process.

The document editing section 1 executes editing processing of a document stored in the document storage section 4 under the control of the document editing control section 2 or the inference section 3. The document editing control section 2 reads out a document to be edited from the document storage section 4 to the document editing section 1, for example, according to various document editing instruction information input from the keyboard 5 via the input control section 6, It also performs the specified editing process on this editing target document.

The document information edited by the document editing section 1 in this manner is displayed on the display 8 via the output control section 7 as appropriate and presented to the operator.

Therefore, when the document editing instruction information input to the document editing control section 2 includes ambiguity, that is, when the input editing instruction information does not specify an editing action on the document, this causes the inference section to 3 is driven. The inference section 3 refers to inference rules, such as those shown in FIG. 3, stored in the inference rule section 7, and infers the editing action intended by the input editing instruction information. That is,
As shown in the left column of Figure 3, this inference rule is based on the fact that editing instruction information (for example, deletion instructions) for instructing an editing action includes a character string that is the target of the editing action instructed by the editing instruction information. In addition to associating multiple parameters (inference parameters) that indicate various attributes (for example, grammatical errors in the target string, presence or absence of modifiers, etc.), each of these parameters is shown in the right column of Figure 3 corresponding to the parameter. This is a rule that shows the relationship with the editing actions shown in (for example, deleting errors or modifiers). here,
The inference parameters are a premise for inferring the editing action instructed by the editing instruction information, and indicate various attributes of the character string that is the target of the editing action. In addition, the editing act indicates a conclusion derived as an inference result based on inference parameters. This reasoning generally leads to multiple editing actions. In accordance with the inference rules, the inference section 3 obtains, for example, the most probable inference result based on probabilistic theory as the editing action intended by the editing instruction information, and controls the document editing section 1 in accordance with this to perform the editing. causing the act to be carried out. The execution results are then presented to the operator via the display 8.

If the editing action of the document based on this inference is different from the editing action intended by the operator in the editing instruction information, for example, the keyboard 5
Information indicating that the editing action is different is input by operating a switch provided at the button. When this information is input, under the control of the document editing control section 2, the inference section 3 again infers the editing action intended by the input editing instruction information. This second inference process is performed excluding the previously inferred result. Therefore, an editing action different from the previous inference result will be inferred.

The document is edited again according to the editing action inferred in this way, and the editing results are displayed again.

This process is repeated until the inferred editing action matches the editing action intended by the input editing instruction information. In other words, as shown in Figure 2,
When an editing instruction including ambiguity is input (step 11), inference parameters are initialized in the inference rule storage section 9. That is, for example, the inference parameters shown at the top of the left column of FIG. 3 are initialized. Next, by inferring the editing instruction according to the set parameters (step 13), the editing action intended by the editing instruction information, for example, the editing action shown at the top of the upper right column in Figure 3, is inferred. and executes the inference result, that is, the selected editing action (step 14). Then, the execution result of this editing action is output (step 15), and an instruction from the operator as to whether the output is acceptable or not is awaited (step 16).
That is, the operator determines whether the output in step 15 is satisfactory or unsatisfactory (step 17), and if unsatisfied, updates the inference parameters set in the inference rule storage section 9. (Step 18) and return to Step 13 to obtain another inference result. That is, in step 18, for example, the inference parameters shown in the second row of the upper left column of FIG. 3 are updated as new inference parameters, and then in step 13, the inference parameters shown in the second row of the upper right column of FIG. The editing action shown in is selected by inference. Then, the processes of steps 13 to 18 are repeatedly executed until a satisfactory editing result is obtained, and the inference process is ended (step 17).

Here, for example, the inference rule for the editing action for ambiguous editing instruction information such as "delete" is as shown in Figure 3: [There is a grammatical error in the character string to be edited] → {Delete the erroneous part} [ There is a grammatical error in the string to be edited, and a modifier has been added to the string] → {Delete the error and the modifier} [A modifier has been added to the string to be edited] → {Modification Delete child} etc. In other words, an editing action is given to edit the content based on the editing instruction information and the document information content to be edited. For example, if a document to be edited is given as ``Claims are a document editing system'' as shown in Figure 4a, and a simple ``delete'' instruction is given, the inference unit 3 first Errors are detected from the ``patent claim'' based on the grammatical rules of the character string, and it is inferred that the editing action is intended to delete the grammatical errors. Then, according to this inference result, a document editing result called "Claims Document Editing System" as shown in FIG. 4b is obtained. On the other hand, if the editing intention is to delete an underline, information indicating that the editing action is different is input as described above.
Upon receiving this information, the inference process obtains the next inference result, for example, ``deletion of modifier,'' and accordingly deletes the underline as shown in FIG. "Document Editing System" to obtain editing results. As a result, the intended editing action is executed from the ambiguous editing instruction of "delete".

Furthermore, even in the case of document editing shown in Fig. 5 a and b,
Similarly, the editing action for the document is inferred from the example of the editing device and executed.

As described above, according to the present device, even if the editing instruction information instructing the document is ambiguous, the document editing is executed according to the editing action inferred from the editing instruction information. In addition, if the inferred editing action is different from the originally intended editing action, simply inputting information to that effect will infer another editing action and execute the document editing, so you can easily perform the intended editing action. It becomes possible to obtain.

Therefore, according to the present device, it is possible to effectively perform document editing, which generally involves the troublesome operation of many keys, simply by inputting simple editing instruction information. Therefore, its usability can be dramatically improved. Moreover, since the inferred editing action can be easily changed, there is no need to construct a sophisticated inference system from the beginning, and the system configuration can be simplified.

Note that the present invention is not limited to the embodiments described above. For example, the inference algorithm for editing actions, the inference rules used in inference processing, etc. may be determined according to the device specifications. Further, the type of editing command may be determined as appropriate. In short, the present invention can be implemented with various modifications without departing from the gist thereof.
