Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an interactive sentence processing device, and more particularly, to an interactive sentence processing device widely used in the field of knowledge information processing and the field of industrial document processing technology.

[Conventional technology]

With the spread of kana-kanji conversion technology and the commercialization of machine translation systems, there is an increasing demand for highly accurate sentence processing technology, but currently correct syntax analysis is achieved using a framework that does not require any human intervention. is extremely difficult. For example, in machine translation systems, a situation arises in which the user must correct errors in the analysis results of the source language. To support this modification, interactive sentence processing devices have been devised that display the main structure of the analysis results to the user (for example, Watanabe et al., "Interactive Japanese Language Analysis Environment: JAWBJ, Information Processing The 38th (first half of 1986) National Conference 6E-7).On the other hand, although there have been no products using systems that reduce the ability to read sentences that are difficult to read or bad sentences, they will become more popular in the future (
C) As documents become more and more digitized, it is expected that there will be a need for such reading comprehension support tools. Considering the feasibility of using existing technology, for example, we can imagine a product that uses sentence analysis technology in machine translation technology to present the deep tree structure as is to the user. I can do two things.

[Problem to be solved by the invention]

However, the problem is that the types of structures that these systems output require a certain amount of learning and training to understand. Therefore, like this? Interactive sentence processing devices have the disadvantage that they cannot be widely used by ordinary users.

[Means to solve the problem]

In order to solve the above problems, an interactive sentence processing device according to the first aspect of the present invention is a sentence processing device that has a function of processing natural language sentences, and is capable of displaying an input sentence and a {l'. E decoration relation designation means; modification range structure creation means for receiving the modification relation designation information outputted by the modification relation designation means and determining the modification range structure of the entire input sentence based on the modification relation designation information; and the modification range +14 structure. Using the modification range structure information outputted by the creation means as input, converting the input sentence into indentation display (display including general line feed, indentation, and indentation processing) using the modification range structure information, and outputting the indentation display information to the display means. and an indentation display means, the input sentence is displayed in an indented manner and ovalized to the user by the display means.

The interactive sentence processing device according to a second aspect of the present invention includes a modification structure constraint storage means for storing control contents related to a modification range in addition to the modification relation specification information, and stores the control contents regarding the modification range in addition to the modification relationship specification information, It is taken out from the storage means and applied.

[Effect]

According to the present invention, instead of displaying analysis results in a wooden elliptical format that can only be understood by language experts, an indented display that can be understood by general users without any training is used to help users understand the results. It becomes possible to display the result of specifying a modification relationship, and it becomes possible to construct a practical interactive sentence processing device for general users.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIGS. 1(a) and (b) are block diagrams showing the configurations of the first and second embodiments of the present invention, respectively, and FIG. 2(a)
and (b) are flowcharts showing the process in which the modification range structure creation means of the first and second embodiments determine the modification range structure of the entire sentence based on the user's specifications, and FIG. 3 is an indentation display generation means. A flowchart showing the process of converting an input sentence into an indented display using qualified range structure information,
FIGS. 4(a) to 4(c) are conceptual diagrams each showing an example of an input sentence, a corresponding modifier function (system specification), and an indented display of the result.

First, the input sentence shown in FIG. 4(a) is long and has many ambiguities regarding the modification range. Even if it is read by a human being, it is unlikely that anyone other than an expert in the relevant field will be able to understand the structure of the sentence at a glance. To resolve this ambiguity, it is considered necessary to understand the meaning of the sentence based on the background technical knowledge information.

Here, assume that such an input sentence is created in a situation where an engineer writes the original text and a technical writer attempts to edit and correct it. A technical writer is an expert in the design and creation of science and technology manuals, and does not necessarily have knowledge of the relevant technical field.

In order for communication to be established between the engineer who wrote this manual document and the technical writer, it is necessary to: ■ not rely on technical terms and concepts from the technical field, and ■ technical terms and concepts from the field of linguistics and natural language processing. It is necessary to establish a mutually understandable and easy-to-understand common language (including diagrams and other formats) that does not depend on each other.These are essential conditions for maintaining practical efficiency. This is because there is not enough time for both parties to learn from each other until they become experts in the other's field.

The input sentence data is once input to the sentence analysis means 5 through the data line 51, and the sentence analysis means 5 sends the input sentence data as it is to the display means 1 through the data line 11. The display means 1 displays input sentence data as shown in FIG. 4(a). The user (i.e. operator) displays the display means 1
The user reads the input sentence displayed on the screen, determines the frame of the sentence based on his or her understanding, selects some embellishment relationships that determine the frame, and specifies them through the modifying relationship specifying means 2.

For example, in the example of the input sentence shown in FIG. 4( , -1), assume that the modification relationship shown in FIG. 4(b) is specified.

The modification range structure creation means 3 receives the modification relation as shown in FIG. Configuring the first and second embodiments according to the procedure in (a) or (b), dividing the input sentence into a group of parts and determining the modification relationship between them, creating modification range structure information as follows. do.

First, in the first embodiment, step 3 is performed as shown in FIG. 2(a).
At 01, the modification range structure creation means 3 receives the output of the modification relation designation means 2. Next, in step 302, points where modification relationships have been specified are connected with pointers to create a modification range structure.

In the second embodiment, it is assumed that the following constraint group is stored in the modified structure constraint storage means 32 as shown in FIG. 2(b).

Modification structure constraint■ “The modification relationship has at least one target
There are only one 1 that appears first, except for one. ” Modification structure constraint ■ “Non-intersection constraint of modification relationship” Modification flI
Construction Constraint ■ ``Things with ambiguity of adjunction/conjunction are recognized as conjunctive.J Based on the above preconditions, we will explain the operation of Modified Range Construction or Means 3.

First, in step 311, the modification range horizontal transfer creating means 3 receives the output of the modification relation specifying means 2. Next, it is checked whether the output received in step 312 satisfies the modified structure constraint group stored in the modified structure constraint storage stage 32. In the case of the above constraints, the modification constraints ■ and ■ apply. The "non-crossing contract of modification relationships" of modification structure constraint (2) is a constraint that requires that the lines connecting the origin and destination of any two sets of dependency relationships in the modification structure do not intersect. To explain this using Figure 5, there are two types of modification structures that occur in the analysis process for the sentence "She likes him..." in Figure 5 (a>, (b)). In Figure 5(a), the lines connecting the hook and the hook intersect, but in Figure 5(b) they do not intersect, so Figure 5(a) has the "non-intersection constraint of modification relationship". Satisfied, Figure 5 (
b) is an unsatisfied modification structure. If a violation is found here, the data line 41.12
A warning message is output to the display means 1 via (step 320). Since the specification in FIG. 4(b) satisfies both constraints (mentioned above), next, in step 313, a modification range structure is created by connecting the location where the modification relationship designation was made with the pointer.

Continuing, in step 314, the created Ihi decorative range structure and the modification +il,7 stored in the modification structure constraint storage 1,000 stages 32
The modification range structure is completed by comparing with the construction constraint group and adding the modification range structure that can be added. For example, in the case of the above constraint, the modification range structure is added to the modification structure constraint (if any).

The indentation display generation means 4 receives the modification range structure information from the modification range structure creation means 3 via the data line 41, converts it into an indentation display for the input as shown in FIG. 4(C), It is output to the display means 1 via the data line 12. The procedure at this time follows the procedure shown in FIG. 3 in this embodiment. That is, first, in step 301, the overall display start position is calculated, and in step 302, indentation display rule 1 is applied to the main predicate and the clauses that depend on it in the modification range structure information, and necessary line breaks and Insert a blank space. Next, in step 403, indentation display rule 4 is applied to the phrase adjacent to the left of the phrase whose display position has been determined in step 402, and necessary line breaks and spaces are inserted. Further move +11 4 0 4 and step 402
, 403, the indentation display rule 2 or 3 is recursively applied to the phrase whose display position has been determined at the end, starting from the left-adjacent phrase of the phrase whose display position has been determined, and necessary line breaks and spaces are inserted.

In the following, when the user instructs the system to analyze the portion according to the indentation display as necessary, the system transfers the modification range structure information stored in the modification range structure creation means 3 from the data line 31 to the sentence analysis means. 5, and the system executes a magistrate sentence analysis according to the indented display.

Although this embodiment has been explained using the index display rules shown in FIG. 3, the present invention is not limited to these specific rules, especially the distinctions such as number of characters and indentation/indentation. ,
Its counterpart is the general processing of line breaks, indentation, and indentation according to a certain set of rules.

〔Effect of the invention〕

According to the present invention, instead of displaying analysis results in a format that can only be understood by language experts, such as a display of analysis results that can be understood only by language experts, it is possible to It becomes possible to display the result of specifying a modification relationship, and it becomes possible to construct a practical interactive sentence processing device for general users.
