DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 4 is a block diagram showing a configuration example of the construction management support device. The configuration of FIG. 4A includes a control device 400 for performing construction management work, a storage device 401 for storing various data, and various data. In other words, it is a stand-alone type device that includes a display device 402 for displaying the device and an input device 403 for designating or inputting equipment. On the other hand, in FIG. 4B, a control device 404 for performing construction management work and a storage device 401 for accumulating various data constitute a server, and the control device 406 for managing exchanges with the server stores various data. A display device 407 for displaying and an input device 408 for designating or inputting equipment constitute a client. There can be any number of clients, and these are connected to the server via the communication means 405.
[0010]
In the apparatus configured as described above, the storage device 401 includes an equipment database 410 storing documents, an equipment dictionary file 411 and an event dictionary file 412 that are features of the present invention. The document describes equipment and events related to it, and is composed of a title and text indicating the content. For example, the title is “A water supply pump leak” and the text is “A water pump causes a leak at x year × month × day ×× and stops operation for XX minutes”.
[0011]
FIG. 3 is an explanatory diagram of a dictionary file. In the equipment dictionary file 411 in FIG. 3A, a set of data in one horizontal row is called a record, and one record corresponds to one equipment. In each record, the name of the corresponding equipment and the terms such as synonyms / synonyms and abbreviations are stored. For example, a specific pump whose facility name is “boiler feed pump” may be called the abbreviation “BFP” or “FP”, but the synonym / synonym “feed pump” (“pump” is double-byte), Or even if it is called “feed pump” (“pump” is half-width), it refers to the same pump. Such a facility dictionary file may be created to some extent in advance, and the contents may be expanded at the time of document registration as described later, or may be expanded at the time of document registration from the beginning. Good.
[0012]
The event dictionary file 412 in FIG. 3B is also the same as the equipment dictionary file described above, and each record corresponds to one event, and each event has an event name indicating the same event and its synonyms / synonyms. Is stored. This creation method is the same as that of the equipment dictionary file, and details will be described later. However, the event dictionary file has no abbreviation here, but it may be added if there is one.
[0013]
FIG. 1 is a flowchart showing a method of registering terms in the equipment dictionary file and event dictionary file and registering a document in a database. This process is executed by the control device 400 in FIG. 4A or the control device 404 in FIG. 4B. However, as means for document reading, operation input, display, etc. used at that time, those other than those shown in FIGS. 4A and 4B may be provided.
[0014]
In the registration process of FIG. 1, first, the title of a document to be registered in the equipment database is read (step 101), the title is decomposed into words, only the nouns are extracted, and stored in the work table (step 102). At this time, it is preferable to display the extracted noun on the display device, remove the irrelevant equipment and event, and store it in the table. Next, one noun is selected from the table and the noun is removed from the table (step 103), and the selected noun is on the equipment dictionary file 411, that is, as the equipment name, abbreviation, or synonym / synonym. It is checked whether it is stored as an event name or synonym / synonym in the event dictionary file 412 (steps 104 and 105). If the selected noun is not in either the equipment dictionary file 411 or the event dictionary file 412, the equipment dictionary file and the event dictionary file are displayed, and the noun is registered to the corresponding one (step 106). The term “applicable” refers to the equipment name or event name that has already been registered, the equipment or event indicated by its synonym, synonym, or abbreviation. When it is not the equipment or event corresponding to the name or its synonym / synonym or abbreviation, it is a new equipment / event name of the equipment dictionary file or event dictionary file or its synonym / similar word or abbreviation. When this registration is completed, or when the name is already in the equipment dictionary file or event dictionary file (Yes in step 104 or 105), it is checked whether there is still a noun in the table. The process of 106 is repeated. When there are no more nouns in the table (No in step 107), both the title and text of the document to be registered are stored in the facility database 110. In this storage, if a title with the same title already exists, the text portion is updated by overwriting.
[0015]
According to the process of FIG. 1 described above, each time a document is registered in the equipment database, the term representing the equipment or event can be stored in the same record as the term representing the same equipment or event. Therefore, when searching the equipment database, the equipment dictionary file and the event dictionary file can be used to easily retrieve necessary documents even if the terms are different. The search method is shown in the flowchart of FIG. This process is executed by the control device 400 in FIG. 4A and the control device 404 in FIG. 4B, and the user performs a search operation from the input device 403 or 408.
[0016]
In the search process of FIG. 2, when a user inputs a term to be searched (step 201), it is checked whether there is a term input in any record of the equipment dictionary file 411 (step 202). All the terms in the record including “name”, that is, the facility name, synonym / synonym, and abbreviation are stored as key words in the work table (step 203). If the entered term is not in the equipment dictionary file, it is checked whether there is the term in any record in the event dictionary file 412 (step 204). If there is a term in the record including the matching case, that is, the event name and All synonyms and synonyms are stored as key words in the work table (step 205). For example, if the term “crack” is input when the event dictionary file of FIG. 3 is provided, “crack”, “chip”, “crack”, and “crack” are stored in the table as key words. When the input term is found in the equipment dictionary file or the event dictionary file and the process in step 203 or 205 is performed, one unread document is next extracted from the equipment database 410 (step 206), and the title of the document Is included in the table, and if it is included, the document is displayed on the display device (step 208). After this display is completed, or when no key word is found in the title (No in step 207), the presence or absence of unread documents in the equipment database is checked (step 209). Exit. In this way, even if a certain facility or event is searched by various terms, a necessary document can be retrieved and displayed by using the facility dictionary file or event dictionary file, and the user can easily search. And you can do it without paying attention to the terminology. For example, when “crack” is input as the target word, if there is a document including “crack” in the document, this document is displayed.
[0017]
If the entered term is neither in the equipment dictionary file nor in the event dictionary file (No in step 202 and step 204), it is a case where there is no term entered in the title. It is checked whether or not there is an input term in the text (description), and if it is found, it is displayed (steps 210 to 213). In this search, if the entered term itself is not in the text, it cannot be searched even if synonyms, synonyms, abbreviations, etc. are used, but most terms used in the search can be registered in the equipment dictionary file or event dictionary file. Step 210 and the subsequent steps are exceptional processes and do not impair the practicality of the apparatus.
[0018]
【The invention's effect】
According to the present invention, a term used by each user on a daily basis is searched as a key, and even when the term is different from the term of the document on the registered facility database, the document is automatically retrieved. Since it is possible to search, the facility database is easy to use and has a great effect on improving workability.
