  Thus, in the conventional building design stage, some of the computers that can be easily calculated from the building design data, such as the calculation of the sky factor disclosed in Patent Document 3, are a computer such as CAD. Although it is automated by software, it is necessary to provide necessary data and to build a dedicated program.

Moreover, since the determination of the item requested | required by a technical document is performed manually, in order to check all the items of a complicated building, much time is required. Although it is possible to realize this judgment with a computer program, it is necessary to create a new judgment program at present, and it is difficult to cope with various building standards in terms of cost effectiveness. .

  Even if a computer program for judgment is created, every time the Building Standards Law is revised or added, it is necessary to modify or add the program, and a large cost is required to maintain the program. Is done.

  The present invention has been made in view of the above problems, and automatically converts a technical standard document described in a certain format into a program for determining whether or not the standard is satisfied using a natural language analysis technique. Therefore, the purpose is to save labor for the conformity judgment of the technical standard document.

Causing the computer to execute a conversion process for creating a conditional expression based on the above and a determination process for collating the conditional expression converted in the conversion process with CAD information of a CAD program for building and outputting a determination result. It is characterized by.

Furthermore, in the technical standard document determination program according to the present invention, the conversion process is A as the source of the dependency on the subject determined in the analysis process, and C as the sentence formed by the subject and the predicate related to the subject. In this case, the conditional expression is created using Expression (1) as a basic expression for the subject.
¬A ∨ C (1)
Where ¬: negation in logical operation, ∨: logical sum

  Furthermore, in the technical standard document determination program according to the present invention, the technical standard document is a single provision in the Building Standard Law.

  Furthermore, in the technical standard document determination program according to the present invention, the conditional expression converted by the conversion process is stored in a storage unit in association with a legal sentence number such as an article or a term. .

  Furthermore, the technical standard document determination program according to the present invention includes a speech recognition process for executing speech recognition on input speech and outputting the text information.

  The technical standard document determination program according to the present invention is based on an analysis process for performing morphological analysis and dependency analysis on a technical standard document composed of text information, and based on an analysis result of the analysis process. A conversion process for converting a document into a conditional expression, and a determination process for collating the conditional expression converted in the conversion process with CAD information of a CAD program for building and outputting a determination result are executed. It is said.

  According to the technical standard document determination program or the technical standard document determination apparatus of the present invention, it is possible to quickly execute whether or not the target building satisfies the technical standard simply by giving the technical standard document composed of text information. It becomes possible to do.

  Furthermore, even when technical standards are revised and added, the computer program for determination is modified and added simply by preparing text information indicating the technical standards, thereby reducing the maintenance cost of the computer program. It becomes possible.

  Further, the technical standard document is not limited to a legal text or the like prepared in advance, but the user himself / herself can make a determination by creating a question text in a predetermined format. For example, while the user is designing, it is possible to determine the point of concern in the design by asking the program by inputting text information from a keyboard or by inputting voice from a microphone.

  FIG. 1 is a diagram showing an outline of the technical standard determination program of the present embodiment. The technical document determination program includes a determination function (conditional expression). A decision process for outputting a decision result is executed by inputting CAD information to be a decision target to the technical standard document decision program. In the present embodiment, since the conditional sentence is stored in association with the legal sentence number such as the article, the clause, etc., it is convenient when the article is revised or added, or when the article is cited in the judgment function. It has a configuration.

  The present invention is characterized in that a technical standard document composed of text information can be easily taken in with respect to the technical standard document determination program. Specifically, as shown in the figure, a natural language analysis is performed on a technical standard document such as a law using Japanese sentences to automatically convert it into a determination function. As the natural language analysis, morphological analysis and dependency analysis are used, and these analysis techniques can be performed using existing computer programs.

  The present embodiment is effective for a technical standard document in which a style has a predetermined format to some extent and conditions are easily set by CAD information. The simple provisions in the Building Standard Law are particularly effective as the object of the present invention because of the nature of the style. In addition, the stand-alone provisions are provisions related to the target building itself, such as structural strength, height, lighting, ventilation, and other safety-related regulations among the provisions stipulated by the Building Standards Act. It can be easily obtained from the CAD information of the target building.

  FIG. 2 is a diagram illustrating the configuration of the technical standard document determination program according to the embodiment of the present invention. In the present embodiment, the technical standard determination program 30 is installed in a general computer device and functions. In addition, since it is necessary to perform processing in cooperation with the CAD program 43, it is necessary to prepare an input / output relationship between the technical standard determination program 30 and the CAD program 43. The technical standard determination program 30 may be configured as a plug-in of the CAD program 43.

The technical standard determination program 30 mainly includes an analysis process 31, a conversion process 32, and a determination process 33. The text information constituting the technical standard document input from the input unit 41 such as a keyboard or an appropriate interface is first subjected to natural language analysis in the analysis processing 31. In this embodiment, text information is analyzed using both morphological analysis and dependency analysis as natural language analysis.

  The analysis result subjected to the natural language analysis in the analysis process 31 is converted into a conditional expression in the conversion process 32. In this embodiment, the converted conditional expressions are accumulated in the storage means 42 and stored in a database, so that a plurality of conditional expressions can be used in combination. When dealing with laws and regulations as technical standard documents, the conditional expressions converted in the conversion process 32 are stored in association with the legal text numbers of articles, paragraphs, etc., so that the legal texts are cited in the conditional expressions. Can do. Furthermore, when the legal text is revised, it is possible to easily determine which conditional expression should be corrected.

  In the determination process 33, based on the conditional expression stored in the storage means 42 and the CAD information received from the CAD program 43, it is determined whether the CAD information, that is, the building being designed satisfies the conditional expression. Execute. This determination may be performed when specified by the user or may be performed when the design of the building is changed. It is also possible to suppress the load necessary for the determination process by determining only the difference with respect to the previous determination.

  As a result of determination in the determination process 33, it is determined whether or not the building satisfies the conditional expression, and a message prompting the user to submit documents required when the predetermined condition is satisfied is presented to the user. Is also possible.

  FIG. 3 is a tree display diagram visually showing an example of an analysis result in the analysis process. In this figure, arrows between chunks surrounded by a square indicate a relationship of mutual dependency. FIG. 4 is a diagram for explaining the relationship between the dependencies in the tree display diagram, in which the chunk located at the start point of the arrow is the origin and the chunk located at the end point of the arrow is the destination. It is shown that.

  Here, as an example of input text information, a sentence “a building with a height exceeding 13 m shall be a fireproof building. However, this is not the case if it falls under each of the following items.” It is picked up. In this specification (the same applies to example sentences used hereinafter), an example sentence obtained by processing the building standard method is used for easy understanding of the explanation. By applying the present invention, it is possible to similarly create a conditional expression for an actual building standard law or other technical standard document.

In the conversion process, the conversion process to the conditional expression is efficiently executed by using the dependency relation in the analysis result. Specifically, centering on the subject, if the sentence relating to the subject S is A, including the predicate and the sentence relating to the subject is C, regarding the subject S, “If S satisfies A, C must be satisfied. In order to express that, the conditional expression is created based on the negative expression of A and the logical sum of C, that is, the following conditional expression (1), which is equivalent to “A⇒C”.
¬A ∨ C (1)
Where ¬: negation in logical operation, ∨: logical sum

In the present embodiment, however, since writing is defined, additional conditions are added. Specifically, if the sentence in the writing portion is E, the conditional expression is defined by the logical sum of conditional expression (1) and E.
¬A ∨ C Ｅ E (Negation of A or C or E)

Now, the conversion process for this example sentence will be described in more detail. FIG. 5 is a flowchart showing analysis processing and conversion processing according to the embodiment of the present invention. First, when the conversion process is started in S101, the result of the analysis process described in FIG. 3 is read. In S102, it is determined whether or not there is a written part in the analysis result. If there is a written part, however, the written part and the other part (text) are distinguished, and the written part is an exception. Save as condition E. In the example sentence, “excluded when it corresponds to each of the following items” following “however” is stored as an exception condition E. The following processes from S104 to S108 are executed for the text.

  In S104, the last predicate in the text is found, and if there is a predicate having a parallel relationship with the predicate, it is also listed. In S105, the subject corresponding to one of the predicates found in S104 is found. Here, the subject (object) S is searched by finding a case directly related to the predicate. In the example sentence, “building is” is stored as the subject S. Furthermore, in S105, the modifier for the subject is stored as application condition A. In the example sentence, the “height exceeds 13 m” portion corresponding to “building is” is stored as the application condition A.

  In S105, the content of what to do with respect to the predicate is extracted. Here, chunks other than the chunks connected by “ha” (corresponding to the subject S) are taken out, combined with the predicate, and stored as the matching condition C.

  In S107, it is determined whether or not the processes in S105 and S106 have been completed for all the predicates found in S104. If there is a remaining predicate, the process returns to S105, and if completed, the process proceeds to the next process S108. In S108, a basic expression (¬A∨C) is formed based on the application condition A and the matching condition C stored for each predicate. When processing is performed for a plurality of predicates, the basic expressions created for each predicate are connected by logical sum or logical product. Which logical function is used for connection may be based on the analysis result of the main text, or a predetermined logical function may be used when the type of the technical standard document to be handled is determined.

  Based on the above conversion process, the text in the example sentence is applied condition A = (“height exceeds 13 m”), subject S = (“building is”), conformance condition C = (“fireproof building” It must be classified as ")".

  In S109, the conditional expression created in S104 to S108 and the write-in part distinguished in S103 are connected with a logical sum to form a conditional expression “¬A∨C∨E”. However, even in the written portion, if necessary, the same conversion processing as that for the text is executed. In addition, although the legal text corresponding to “next number” is not described in the proviso of this example sentence, a conditional expression is actually created for “numbers” following the example sentence.

  In the above conversion processing, the object S, the application condition A, the conformance condition C, and the exception condition E necessary for creating the conditional expression can be specified, and this can be specified as C #, VisualBasic, Java (all Describe in a grammar that matches the programming language (registered trademark). In the following, description will be given of a case where a function is described in Visual Basic grammar, but the flow of processing is the same in other programming languages.

As a first step, a basic expression part “¬A∨C” in the conditional expression “¬A∨C∨E” is created.
Function Complies () As Boolean
Complies = Not A Or C
End Function

Each of the A and C parts of the template
Architecture.Complies ("height exceeds 13m")
Buildings.Complies (“Fireproof building”)
Replace
Function Complies () As Boolean
Complies = Not Architecture.Complies ("Height exceeds 13m")
Or Building.Complies (“Fireproof Building”)
End Function
The function is output.

If there are multiple predicate list elements,
Complies = Not A Or C
Part of
Complies = (Not A Or C) And (Not A Or C) And…
In this way, conditional expressions can be created by taking the logical product of the basic expressions corresponding to each predicate.

Further, if there is a writing, a “∨ E” portion is created as the second stage. Specifically, the conditional expression and E are connected by Or (logical sum).
Complies = ((Not A Or C) And (Not A Or C) And…) Or E

Through the above processing, the example sentence can be converted into the following program.
Function Complies () As Boolean
Complies = (
Not Building.Complies ("Height exceeds 13m")
Or Building.Complies (“Fireproof Building”)
)
Or
Complies ("Applicable to the following items")
End Function

  In order to actually execute, it is replaced with a different function name. The replacement with the function name may be prepared in advance on the CAD program side, or may be performed by the conversion processing in the present embodiment. For example, “building.Complies (“ fireproof building ””) ”in the above conditional expression is replaced with“ building.IsFireResistant () ”.

The function name required for this replacement process is “Building.Complies (“ Fireproof building ”)”
, Prepare what is supposed, such as “Building.Complies (“ Wooden ”). In addition, when individual determination functions such as “building.IsFireResistant ()” are not prepared in the CAD program, these functions are created separately.

  As described above, the analysis process and the conversion process according to the embodiment of the present invention have been described in detail by taking the unit rules in the Building Standard Law as examples, and following the process, but each processing method is limited to this embodiment. There is nothing, and it is possible to adopt a method as appropriate according to the style of text to be handled.

  Then, some example sentences are given about the embodiment in which the simple provisions in the Building Standard Law are partially changed and used as example sentences. 6 to 8 are diagrams showing the analysis result tree display and the application results of the subject S, the application condition A, and the adaptation condition C in the conversion process, as in the first embodiment.

Fig. 6 shows an example sentence of a single provision in the Building Standards Law: "A building with a living room that does not have a window specified by a Cabinet Order or a building with a total area of more than 1,000 square meters, And the fire-fighting shall not be hindered. " As can be seen from the analysis result of the tree display diagram, in this example sentence, the matching condition C is commonly used, and two basic expressions having different application conditions A are connected by a logical product.
(¬A ∨ C) ∧ (¬A '∨ C)
Can be expressed as The subjects S1 and S2 are “buildings” and are common.

Fig. 7 shows an example of a single provision in the Building Standards Law: “A building with a total area of more than 1,000 square meters is effectively partitioned by a fire wall with a structure effective for fire prevention, and the total floor area of each partition is 1,000 square meters. It must be within. " In this example sentence, the application condition A and the subject S are common, and the matching condition C is different. Moreover, since it can be understood that the logical product of the two basic expressions can be obtained from the example sentence, the conditional expression is
(¬A ∨ C) ∧ (¬A ∨ C ')
Can be expressed as

Figure 8 is a simple example sentence in the Building Standards Law, “Towers with a height of more than 12 m or buildings with a height of more than 9 m meet the standards set forth in Article 2, item 9-2. It is a case where “I have to do it” is adopted. In this example sentence, as in the case of FIG. 6, the matching condition C and the subjects S1 and S2 are common, and the application conditions are different. Therefore, the conditional expression is the same as in FIG.
(¬A ∨ C) ∧ (¬A '∨ C)
Can be expressed as

  In the example sentence of FIG. 8, the legal condition number “No. 2 of Article 9” is included in the matching condition C. Therefore, by storing the conditional expression associated with the legal text number in the storage means in advance, the conditional expression corresponding to “Article 2-9 No. 2” is read out, added to the conditional expression, and determined. Possible conditional expressions are possible.

  As described above, the application examples of FIGS. 6 to 8 have been described using the tree display diagrams showing the analysis results. In these sentence examples as well, the basic formula (¬A） C) described in the first embodiment is combined. This makes it possible to create conditional expressions.

  FIG. 9 is a diagram for explaining the configuration of a technical standard document determination program according to another embodiment. In the present embodiment, it is configured to be able to execute determination on text information and audio signals input from the user in real time by the input unit 41 such as a keyboard or the microphone 41a. A voice signal from the microphone 41 a is converted into text information by the voice recognition process 34 and input to the analysis process 31. In the analysis processing 31, natural language analysis by morphological analysis and dependency analysis is executed as in the above-described embodiment.

  The analysis result is transferred to the conversion process 32, where it is converted into a conditional expression. In the above-described embodiment, the conditional expression is temporarily stored in the storage unit. However, in this embodiment, since the voice signal or text information input from the user is determined in real time, the database in the storage unit is used. There is no conversion. In the determination process 33, a determination result is output based on the converted conditional expression and the CAD information from the CAD program 43. When other conditions are required for the determination, the determination is executed using various conditional expressions and various definitions stored in advance in the storage unit 42.

As described above, in the present embodiment, it is possible to determine whether or not the design contents satisfy a question in a predetermined format inputted in real time from the user in the course of designing the building by the CAD program. For example, if a question such as “Is the evacuation route 20m or less?” Is asked to the computer device while designing, a design environment for determining whether the building under design satisfies this question is realized. it can.

  Note that the present invention is not limited to these embodiments, and embodiments configured by appropriately combining the configurations of the respective embodiments also fall within the scope of the present invention.
