  By the way, the work of constructing an ontology is often performed manually by a builder. However, it is difficult to build an ontology unless you are an expert who is familiar with the ontology and has enough experience. In recent years, with technological innovation and the development of new methods, the business knowledge has become enormous and the knowledge is diverse. Therefore, it takes a lot of labor and time to construct an ontology.

  The present invention has been made in view of the above circumstances, and one of its purposes is an ontology construction support apparatus that can reduce the burden on the builder and support efficient construction of the ontology, and a program thereof And providing a computer-readable recording medium in which the program is recorded.

  The ontology construction support device of the present invention is based on the ontology of the achievement relationship of these procedures, with the overall procedure and the partial procedure sequence subdivided based on the achievement method for achieving the procedure as a parent node and a child node, respectively. It is an ontology construction support device that supports construction of procedural decomposition trees expressed in a tree structure. The apparatus according to the present invention includes an input unit, a storage unit, a procedure node generation unit, and a display unit. The input means inputs a sentence describing the achievement relationship between the overall procedure and the partial procedure sequence related to the work. The storage means stores the input sentence. The procedure node generation means extracts a verb representing an action from a sentence, generates a corresponding node as a procedure node, and assigns the extracted verb to the procedure node. The display means displays the generated node.

The program of the present invention is a program for causing a computer to function as the ontology construction support apparatus of the present invention described above, and specifically, is a program for causing a computer to function as the following means.
An input means for inputting a sentence describing the achievement relationship between the overall procedure and the partial procedure sequence related to the business.
Storage means for storing input sentences.
Procedure node generation means for extracting a verb representing an action from a sentence, generating a corresponding node as a procedure node, and assigning the extracted verb to the procedure node.
Display means for displaying the generated node.

  The recording medium of the present invention is a computer-readable recording medium that records the above-described program of the present invention.

  The above-described procedure decomposition tree is a tree structure representing the relationship between the overall procedure and the partial procedure sequence obtained by subdividing the procedure based on the ontology. More specifically, the overall procedure is obtained by repeatedly decomposing the entire procedure into a sequence of partial procedures based on the achievement method for achieving the procedure (hereinafter, this may be referred to as “procedure decomposition”). Is represented as a parent node and a partial procedure as a child node in a tree structure. If it is possible to further decompose a partial procedure, multiple partial hierarchies can be created by connecting (linking) subsequences of subprocedures as subnodes and connecting them as child nodes of child nodes. It becomes a tree structure. In the procedure decomposition tree, a node representing a procedure (action) is called a procedure node, and a detailed partial procedure appears in a lower hierarchy. In the procedural decomposition tree, the size of a concept represented by a node is called a granularity (grain size), and the granularity is large in the upper hierarchy and becomes smaller toward the lower hierarchy. Then, by using the procedure decomposition tree, it is possible to systematically understand what partial procedure sequence the target overall procedure can be achieved based on. Such a procedure decomposition tree can be constructed on the basis of a sentence (document) describing the achievement relationship between the overall procedure and the partial procedure sequence related to the business, generally a procedure manual.

  According to the ontology construction support apparatus of the present invention, by providing a procedure node generation means for generating a procedure node from an inputted sentence, it is not necessary for a builder to manually create a procedure node, and the procedure node is semiautomatically created. Is generated. Therefore, the burden on the builder can be reduced and efficient construction of the procedure decomposition tree can be supported.

  Here, the text to be input may be directly input manually by the builder based on the procedure manual, or may be input from the read electronic document by reading the digitized procedure manual.

  Further, according to the program of the present invention, it is possible to cause a computer to function as the ontology construction support device of the present invention described above. According to the recording medium of the present invention, the above-described program of the present invention is read by a computer and executed, thereby allowing the computer to function as the above-described ontology construction support apparatus of the present invention.

  According to this configuration, when a word suggesting an inhibition factor appears in the sentence, the inhibition factor node generation unit that generates an inhibition factor node corresponding thereto is provided. As a result, it is not necessary for the builder to manually create the inhibition factor node, and the inhibition factor node is generated semi-automatically. Therefore, the burden on the builder can be reduced and efficient construction of the procedure decomposition tree can be supported. Here, as the wording that suggests the inhibition factor, for example, “XX as an inhibition factor”, “XX as an obstruction event”, “Inhibition of XX (disturbance)”, “Fail to XX”, “○ “Risk to do”, “Prevention (prevention) of XX”, “Attention to XX”, “Problem of XX”, “Problem of XX”, “Need to solve XX”, “Handling XX” Words (words, terms, phrases) representing an obstruction factor (risk) such as “necessary to do”.

  As an embodiment of the ontology construction support apparatus of the present invention, there is a configuration including at least one of a coping node generation unit and a prevention node generation unit. When a word suggesting a countermeasure against the obstruction factor appears in the sentence, the coping node generation means extracts the wording, generates a corresponding node as a coping task node, and is extracted to the coping task node. Give the word. The preventive node generation means, when a word suggesting a preventive method for the obstruction factor appears in the sentence, extracts the word, generates a corresponding node as a preventive task node, and is extracted to the preventive task node. Give the word.

  According to this configuration, when a word suggesting a countermeasure or prevention method for an obstruction factor appears in the sentence, the countermeasure node generation means or the prevention node generation means for generating the corresponding task node or prevention task node is provided. Prepare. As a result, it is not necessary for the builder to manually create a countermeasure task node or a preventive task node, and a countermeasure task node or a preventive task node is generated semi-automatically. Therefore, the burden on the builder can be reduced and efficient construction of the procedure decomposition tree can be supported. Here, as a word suggesting a coping method, for example, “Correction by XX (Solution)”, “Correction method (Solution) as XX”, “Corresponding by XX”, “Process XX” , A word (word, term, phrase) representing a coping method (solution) such as “select XX in case of (implementation)”. In addition, the wording that suggests the prevention method is, for example, “Prevention (prevention) by ○○”, “Prevention method (prevention method) ○○”, “For prevention of ○○”, “Safely ○○ Words (words, terms, phrases) representing preventive methods (prevention methods) such as “for”, “perform XX in advance”, “for precaution”.

  Note that each of the generated nodes is a temporary node, and the builder may delete it appropriately if the content is duplicated based on the procedure manual, or may add it appropriately if it is insufficient. . Further, the verbs and words given to the above nodes may be edited as appropriate after the nodes are generated.

  As one form of the ontology construction support device of the present invention, a node grouping that searches a sentence suggesting a purpose from a sentence and groups each node generated from within a predetermined range based on the appearance position of the sentence The structure provided with a means is mentioned.

  It can be said that the procedure decomposition tree is a procedure that decomposes the target overall procedure (goal action) into partial procedure sequences (sub-action sequences) in a goal-oriented manner and expresses the achievement relationship of procedures in a tree structure. As a result of the study by the present inventors, in a sentence, in order to achieve the objective overall procedure (goal action) and the procedure in the vicinity of a word suggesting the objective, for example, the word “object” or “reason” It turned out that a partial procedure sequence (sub-action sequence) is often described. That is, in many cases, a partial procedure sequence based on the achievement method for one overall procedure is described in the vicinity of the words “purpose” and “reason”. According to the above configuration, the node grouping means for grouping each node generated from within a predetermined range on the basis of the appearance position of the word suggesting the purpose in the sentence is provided. This facilitates the creation of a tree structure representing the achievement relationship between one overall procedure and its partial procedure sequence. Here, the predetermined range is not particularly limited. For example, the range is the number of words set from the appearance position of the word suggesting the purpose (eg, 200 words before and after), or the word suggesting the purpose. And the range of chapters and paragraphs that contain. In addition to the above words such as “purpose” and “reason”, for example, words (words, terms, phrases) such as “for” and “so” may be used as the word suggesting the purpose.

  As one form of the ontology construction support device of the present invention, the procedure node is provided with object information providing means for assigning object information related to the object of the action, and the object information is associated with the procedure node in the display means. A configuration in which the information is displayed is shown.

  According to this configuration, the object information can be given to the procedure node and displayed, so that the builder can be made aware of the flow of the procedure including the object. This makes it easy for the builder to be aware that the granularity of procedure nodes representing partial procedures is kept constant. By keeping the granularity of the procedure nodes representing the partial procedure constant, the consistency of the procedure is maintained, and the reusability of the partial procedure decomposition tree is improved.

  In the form provided with the above-mentioned object information giving means, when object information is given to a plurality of procedure nodes, it is preferable to display the same object information in the same form on the display means. .

  According to this configuration, by displaying the same object information in the same form, it is easy for the builder to recognize the same object and to make the flow of the procedure including the object more conscious. Here, when displaying the same object information in the same form, for example, the same object information may be displayed in the same color or pattern, or the shape of the frame displaying the same object information may be the same. Can be mentioned.

  As an embodiment of the ontology construction support apparatus of the present invention, there is a configuration including a database connection unit and a search image display unit. The database connection means connects to a database in which business-related images are stored. The search image display means searches the database for an action corresponding to the procedure node, and displays the searched image on the display means.

  It is desirable that the words (words, terms, phrases) given to the procedure node are expressed by a finite number of functional vocabularies with clearly defined meanings. As a result, the procedure decomposition tree can be expressed based on the common vocabulary (concept), so that it is easy to obtain a common understanding among the builders, and the reusability is improved. According to the above configuration, an image related to an action corresponding to a procedure node is searched from the database, and the image is displayed to assist the builder to recall / associate a functional vocabulary representing the procedure (action). it can. Here, the database may be stored in a storage means inside the apparatus, or may be placed on an external network (local area network, Internet, etc.). The above-mentioned image includes a moving image in addition to a still image.

  As an embodiment of the ontology construction support apparatus of the present invention, there is a configuration including a link generation unit and a warning generation unit. The link generation means generates a link between designated nodes. The warning generation means issues a warning when the number of child nodes representing the partial procedure sequence based on one achievement method exceeds the set number with respect to the parent node representing the entire procedure.

  Each node generated by each of the node generating means is independent and has no link between the nodes at the time of generation. Therefore, the builder creates a tree structure by creating a link between the nodes by the link generation unit based on the procedure manual. The procedure decomposition tree is a tree structure representing the relationship between the overall procedure and the partial procedure sequence obtained by subdividing the procedure based on the achievement method. A plurality of child nodes representing partial procedure sequences based on the achievement method are linked. Here, in the procedural decomposition tree, the deeper the hierarchy, the more useful the knowledge that can be obtained, and it can be expected to express implicit knowledge, so it is important to make it hierarchical (structured) . However, if a tree structure is created without being aware of this, the number of child nodes representing partial procedures in one hierarchy tends to increase, and the hierarchy does not become deep. According to the above configuration, when the number of child nodes representing the partial procedure sequence based on one achievement method exceeds the set number with respect to the parent node representing the entire procedure, the warning generation means issues a warning, The builder can be made aware of the hierarchy of procedure decomposition trees. The number of set partial procedures (child nodes) is preferably in the range of 3-5.

  In the form including the link generation means described above, a partial procedure sequence based on one achievement method is further represented for the server connection means for connecting to the server in which the information related to the business is stored and the parent node representing the overall procedure. When the number of child nodes exceeds the set number, AND search is performed in the server for the word representing each action assigned to two or more child nodes specified from the child node and the word of purpose or reason in the server. An AND search display means for displaying the result on the display means is preferable.

  If the number of child nodes representing a partial procedure sequence based on one achievement method exceeds the set number for the parent node representing the entire procedure, the partial procedure represented by two or more child nodes from the child node group It is desirable to make the hierarchy deeper by making the concept higher. According to the above-described configuration, the AND is searched for in the server the wording representing each action given to two or more child nodes and the word of purpose or reason, and the search result is displayed. Can support the imagination and creation of superordinate concepts. Here, the server is placed on, for example, an external network (such as a local area network or the Internet).

  As one form of the ontology construction support apparatus of the present invention, a moving picture storage means that represents a partial procedure sequence based on one achievement method and stores a series of moving pictures divided for each partial procedure, and constructed procedure decomposition When a tree and a video timeline are displayed and a partial video representing a partial procedure on the timeline is selected, a list of words representing each action assigned to all procedure nodes in the procedure decomposition tree is displayed. And a user interface means for giving a word selected from the list as a tag of the partial moving image.

  When using a procedure decomposition tree for business support, knowledge sharing, etc., it is possible to confirm and learn a business procedure by displaying the procedure decomposition tree for a worker (worker). In that case, since there is little information (knowledge) obtained only with the wording which represents the action given to the procedure node, it is preferable to display an image (moving image) showing the action given to the procedure node by an input operation. Therefore, it is desirable that the ontology construction support apparatus includes user interface means for performing editing that associates a moving image with a procedure node.

  The moving image described above is a series of moving images representing a partial procedure sequence based on one achievement method, and is divided in advance for each partial procedure. In the initial state, no tag is assigned to the partial video representing the partial procedure, and a tag needs to be assigned. According to the above configuration, when a partial video on the timeline is selected, a list of words representing each action assigned to all procedure nodes is displayed, and the word selected from the list is used as a tag for the partial video. Can be granted. Therefore, it is not necessary for the builder to manually input the tag of the partial moving image, and the tagging operation of the partial moving image can be performed efficiently.

  As one form of the ontology construction support apparatus of the present invention, a moving picture storage means that represents a partial procedure sequence based on one achievement method and stores a series of moving pictures divided for each partial procedure, and constructed procedure decomposition A tree and a video timeline are displayed, a procedure node in the procedure decomposition tree is selected, and dragged and dropped onto a partial video representing a predetermined partial procedure on the timeline. And a user interface unit that assigns a word representing an action as a tag of the partial moving image.

  In the embodiment including the above-described user interface means for displaying a list of words representing each action assigned to all procedure nodes, the configuration for selecting a tag to be assigned to a partial moving image from the list has been described. According to this configuration, by dragging and dropping a procedure node of a procedure decomposition tree onto a predetermined partial video on the timeline, a word indicating an action given to the procedure node is given as a tag of the partial video Can do. Therefore, it is not necessary for the builder to manually input the tag of the partial moving image, and the tagging operation of the partial moving image can be performed efficiently.

  As one form of the ontology construction support apparatus of the present invention, a moving picture storage means that represents a partial procedure sequence based on one achievement method and stores a series of moving pictures divided for each partial procedure, and constructed procedure decomposition Display the tree and the timeline of the video, select the partial video that represents the partial procedure on the timeline, and drag and drop it to the specified procedure node in the procedure decomposition tree, so that the information of the partial video is And a user interface means for giving to the procedure node.

  In the initial state, the information on the partial video is not assigned to the procedure node, and it is necessary to associate (associate) the procedure node with the corresponding partial video. According to this configuration, by dragging and dropping a predetermined partial moving image on the timeline to the procedure node of the procedure decomposition tree, information on the partial movie can be given to the procedure node. Therefore, it is not necessary for the builder to manually input partial video information to the procedure node, and the procedure node and the partial video can be efficiently associated with each other.

  In the ontology construction support apparatus of the present invention, the procedure node is generated semi-automatically from the input text, so that the burden on the builder can be reduced and efficient construction of the procedure decomposition tree can be supported.

  The program of the present invention can cause a computer to function as the ontology construction support device of the present invention described above. Further, the recording medium of the present invention allows the computer to function as the ontology construction support apparatus of the present invention described above by causing the computer to read and execute the program of the present invention described above.

  Embodiments of the present invention will be described below with reference to the drawings. Here, the procedure decomposition tree will be described first, and then the ontology construction support apparatus of the present invention will be described.

  FIG. 1 is an example in which a procedure decomposition tree of a procedure “saving” is described based on a procedure manual (guideline) for medical work. This procedure decomposition tree is obtained by repeatedly decomposing the procedure of “saving” into a sequence of partial procedures based on an achievement method for achieving the procedure. Specifically, the procedure of “saving lives” is achieved by the “cardiopulmonary resuscitation method”, and “prepare”, “provide oxygen to the brain”, and “change the position of the victim” based on this achievement method It can be broken down into three partial procedures, which are realized by a sequence of these partial procedures. These procedures (acts) are used as procedure nodes, and the achievement relationship of these procedures is expressed in a tree structure. Specifically, the procedure node representing “saving” of the overall procedure is a parent node, and each procedure representing “prepare”, “provide oxygen to the brain”, and “change the position of the victim” in the partial procedure sequence The node is linked as a child node.

  Furthermore, the “preparation” procedure among the three partial procedures described above is achieved by the “cardiopulmonary resuscitation preparation method”, and based on this achievement method, “confirm safety”, “protect infection”, and “consciousness”. It can be broken down into five subprocedures, “Confirm”, “Collect” and “Confirm breathing and pulse”, which are realized by a sequence of these subprocedures. Then, the procedure node representing “preparation” of the entire procedure is set as a parent node, and “confirm safety”, “protect infection”, “confirm consciousness”, “collect”, “breath and pulse” in the partial procedure sequence. Each procedure node representing “confirm” is linked as a child node. The procedure of “providing oxygen to the brain” is achieved by the “method of giving oxygen to the brain”, and based on this achievement method, “ventilate”, “push on the ribs”, “defibrillate” It can be broken down into three partial procedures, which are realized by a sequence of these partial procedures. Then, the procedure node representing “provide oxygen to the brain” of the overall procedure is set as a parent node, and each procedure node representing “ventilate”, “press on the rib”, and “defibrillate” in the partial procedure sequence is a child. Linked as a node.

  In the procedure decomposition tree shown in FIG. 1, a subtree having a procedure node representing “saving” as a root node represents an achievement method for achieving the “saving” procedure and a partial procedure sequence based on the achievement method. A procedure node representing a detailed partial procedure is located in a lower hierarchy. In the procedure decomposition tree shown in FIG. 1, child nodes of the same hierarchy are arranged in order of partial procedures from the left. In addition, a procedure node representing a procedure (action) is indicated by an ellipse, a method node representing an achievement method is indicated by a square, and a method node is arranged on a link between the procedure nodes.

  A procedure decomposition tree having a plurality of achievement methods (alternative procedures) for achieving the procedure will be described. FIG. 2 is an example in which a procedure decomposition tree of the procedure “secure airway” is described. The procedure of “securing the airway” can be achieved by three methods: “natural airway use method”, “artificial airway insertion method”, and “natural airway incision artificial airway installation method”. There is a sequence of partial procedures based on the scheme. As shown in FIG. 2, in the procedure decomposition tree, there is a partial tree in which a procedure for “reserving an airway” is represented by a sequence of partial procedures based on the method, depending on each method.

  A description will be given of a procedure decomposition tree having a pattern including an obstruction factor when performing the procedure. FIG. 3 is an example in which a procedure decomposition tree of the “ventilate” procedure, which is a part of the partial procedure based on the “method for giving oxygen to the brain” shown in FIG. 1, is described. The procedure “ventilate” is achieved by “ventilation method” and is realized by a sequence of partial procedures based on this method of achievement. Further, the “ventilation” procedure has an obstruction factor (risk) such as “air enters the stomach” and “low oxygen concentration” when the procedure is performed. The inhibition factor node representing the inhibition factor is linked to the procedure node representing “ventilate”.

  A procedural decomposition tree of patterns including obstruction factors and countermeasures will be described. FIG. 4 is an example in which the inhibition factor and the countermeasures are described in the procedure decomposition tree of the “ventilate” procedure shown in FIG. In the “ventilating” procedure, there is “low oxygen concentration” as an inhibiting factor when the procedure is performed, and “bag valve mask system with reservoir” is a countermeasure against the inhibiting factor. Then, a countermeasure task node representing a “bag valve mask system with reservoir” as a countermeasure for the inhibition factor is linked to the inhibition factor node representing the “oxygen concentration is low” as the inhibition factor. If there is a prevention method for the inhibition factor, the prevention task node representing the prevention method is linked to the inhibition factor node in the same manner as the countermeasure task node.

[Example 1]
The configuration of the ontology construction support apparatus according to the present invention is shown in FIG. An ontology construction support apparatus according to the present invention is an apparatus that supports construction of a procedure decomposition tree as described above, and includes an input unit 1, a storage unit 2, a node generation unit 3 including a procedure node generation unit, and a display unit. 4. The input means 1 inputs a sentence describing the achievement relationship between the overall procedure and the partial procedure sequence related to the work. The storage means 2 stores the input sentence. The node generation means 3 includes a procedure node generation means. The procedure node generation means extracts a verb representing an action from a sentence, generates a corresponding node as a procedure node, and extracts the extracted verb to the procedure node. Give. The display unit 4 displays the generated node.

  In this example, the node generation unit 3 includes an inhibition factor node generation unit, a countermeasure node generation unit, and a prevention node generation unit in addition to the procedure node generation unit. When a word suggesting an obstruction factor when performing a procedure appears in a sentence, the obstruction factor node generation means extracts the word, generates a corresponding node as an obstruction factor node, and the inhibition factor Assign the extracted word to the node. When a word suggesting a countermeasure against the obstruction factor appears in the sentence, the coping node generation means extracts the wording, generates a corresponding node as a coping task node, and is extracted to the coping task node. Give the word. The preventive node generation means, when a word suggesting a preventive method for the obstruction factor appears in the sentence, extracts the word, generates a corresponding node as a preventive task node, and is extracted to the preventive task node. Give the word. In each of the node generation means described above, extraction and retrieval of verbs and phrases from sentences (documents) can be realized by using a known natural language analysis technique.

  An operation example of the ontology construction support apparatus according to the present invention described above will be described. As shown in FIG. 6, the builder B manually inputs into the ontology construction support apparatus S based on the procedure manual (paper medium), which describes the achievement relationship between the overall procedure and the partial procedure sequence related to the work, or The computerized procedure manual (electronic document D) is input to the ontology construction support apparatus S and read from the input electronic document D. The ontology construction support device S extracts the verbs and words determined from the input text by each of the node generation means described above, generates a corresponding node, and gives the extracted verbs and words to the node. To do. Then, the ontology construction support apparatus S displays each generated node as shown in the lower part of FIG. For example, in FIG. 6, five verbs representing actions (acts 1 to 5) are extracted from the sentence, five procedure nodes 101 to 105 corresponding to each action, and one word suggesting an obstruction factor are extracted. One inhibition factor node corresponding to the inhibition factor indicates a generated state. In this example, in order to easily distinguish the procedure node and the inhibition factor node, both are displayed in different colors.

  According to the apparatus of this example, by providing each node generating means such as a procedure node generating means, each node such as a procedure node can be generated semi-automatically from the input sentence. Therefore, it is not necessary for the builder to manually create each node, and the burden on the builder can be reduced and efficient construction of the procedure decomposition tree can be supported.

  Each generated node is a temporary node, and the builder can delete it appropriately when the content is duplicated or add it appropriately when it is insufficient, based on the procedure manual. Moreover, the verbs and words given to each node can be edited as appropriate after the node is generated.

  Further, in the ontology construction support device according to the present invention described above, when a word suggesting the achievement method appears in the sentence, the word is extracted and registered as a candidate label of the achievement method. A configuration including means may be added. As a result, when the builder assigns the label of the achievement method, the registered method label candidates are displayed and selected from the candidates, thereby reducing the burden on the builder and efficiently performing the label assignment work. be able to.

[Example 2]
In this example, in the ontology construction support apparatus according to the present invention described above, a word suggesting a purpose is searched from a sentence, and each node generated from a predetermined range based on the appearance position of the word is grouped. A configuration provided with node grouping means will be described.

  The device of this example searches a word that suggests a purpose from the input text by the node grouping means, specifically the word “purpose” or “reason”, and uses the appearance position of the word as a reference, Each node generated from within the range is grouped (see FIG. 7). For example, in FIG. 7, a node (in this case, procedure nodes 101 to 103) generated by extracting a verb or wording within a predetermined range from the appearance position of the first word in the sentence, and the second Nodes (here, procedure nodes 104 and 105 and inhibition factor node 201) generated by extracting verbs and words within a predetermined range from the appearance position of the above words are grouped into two nodes. Indicates that the group has been created. In this example, in order to make it easy to distinguish which group a node belongs to, as shown in FIG. 7, nodes belonging to the same group are displayed surrounded by a frame.

  According to the apparatus of this example, each node generated from the vicinity of the words “purpose” and “reason” in the sentence can be automatically grouped. In the vicinity of the words “purpose” and “reason”, a partial procedure sequence based on the achievement method for one overall procedure is often described. It is easy to create a tree structure that represents the achievement relationship with the procedure sequence.

[Example 3]
In this example, in the ontology construction support apparatus according to the present invention described above, a configuration including link generation means for generating a link between designated nodes will be described.

  As shown in FIG. 6, each node generated by each node generation means is independent because no link is established between the nodes at the generation stage. The apparatus of this example includes link generation means, and a builder can generate a link between nodes based on a procedure manual. Specifically, by creating a link between a procedure node representing the entire procedure and each procedure node representing a partial procedure sequence based on one achievement method, and defining a parent-child relationship between these nodes, A tree structure can be created.

  In the link generation means, an operation for generating a link includes, for example, generating a link between the displayed nodes by dragging between the displayed nodes. Moreover, as operation which cut | disconnects a link, cutting | disconnecting a link is mentioned, for example by dragging across the displayed link. These operations are intuitive and easy to understand.

  Furthermore, as a modified example, a plurality of templates of procedural decomposition tree patterns may be registered, and a tree structure may be created by applying template options and generated nodes from the templates to the template.

[Example 4]
In this example, in the ontology construction support apparatus according to the present invention described above, the procedure node is provided with target object information giving means for giving target object information related to the target object of the action, and in the display means, the target information is processed. A configuration for displaying in association with a node will be described.

  The apparatus of this example is provided with the object information provision means, The builder can provide the object information regarding the object of the action with respect to a procedure node. The display means displays the object information given to the procedure node in association with the procedure node. FIG. 8 is an example in which object information is given to a procedure node in a procedure decomposition tree for a lifesaving procedure that gives an electric shock. In this example, for example, “patient” that is the object of the action in the procedure node representing “applying an electric shock”, and object information “AED” that is the object of the action in the procedure node representing “turn on” Is granted. As shown in FIG. 8, the assigned object information 151 and 152 are displayed in association with the respective procedure nodes 111 to 114.

The procedure decomposition tree shown in FIG. 8 is constructed by inputting the following text into the ontology construction support apparatus according to the present invention and generating a procedure node semi-automatically by the above-described procedure node generation means based on this text. doing.
(Input text)
“Attach the electrode pad to the chest of the patient (patient). Press the shock button. After applying the electric shock, follow the message to resume cardiopulmonary resuscitation immediately.”

  Here, the procedure node in the procedure decomposition tree shown in FIG. 8 is edited so that the meaning given to the procedure node generated by extracting the verb representing the action from the above sentence can be easily understood. Yes. Specifically, in the sentence, the procedure node generated from “Attaching the electrode pad to the chest of the patient (patient)” is the procedure generated from “Place the pad” and “Press the shock button”. The wording of the procedure node generated from “switch on” and “after applying electric shock” is edited to “apply electric shock”.

  In this example, the same object information is displayed in the same form for the object information 151 and 152 displayed in association with each of the procedure nodes 111 to 114, and specifically, in the same color. it's shown.

  According to the apparatus of this example, the object information is given to the procedure node and displayed, so that the builder can be made aware of the procedure flow including the object. Thereby, the builder can confirm the granularity of the procedure node representing the partial procedure, and easily recognize that the granularity of the procedure nodes representing the partial procedure is kept constant. Moreover, since the same object information is emphasized by displaying the same object information in the same form, it is easy for the builder to recognize the same object, and the flow of the procedure including the object is further improved. Easy to be conscious.

  Further, in FIG. 8, a method label 351 is assigned to the method node 301 representing the achievement method. The apparatus of this example includes the above-described method label candidate registration means, and the method of assigning method labels is performed by displaying the label candidates registered by the method label candidate registration means and selecting from among the label candidates. The system label can be given.

[Example 5]
In this example, a configuration including a database connection unit and a search image display unit in the ontology construction support apparatus according to the present invention described above will be described. The database connection means connects to a database in which business-related images are stored. The search image display means searches the database for an action corresponding to the procedure node, and displays the searched image on the display means.

  For example, as shown in the upper part of FIG. 9, when the procedure node 104 in the procedure decomposition tree is selected (for example, left click of the mouse), a menu is displayed on the right side of the node, and when “image search” is selected from the menu item. , Start to search for images. In this image search, for example, a database on the external network is accessed by the database connection means, and the action (act 4) corresponding to the selected procedure node (here, procedure node 104) is performed on the database by the search image display means. Search from. Then, as shown in the lower part of FIG. 9, the searched image 400 is displayed on the display means by the search image display means.

  According to the apparatus of this example, a function vocabulary representing a procedure (action) is recalled and associated with a builder by searching the database for an action related to the procedure node and displaying the image. Can support.

  Further, the image searched from the database may be assigned in association with the selected procedure node, and when the operator uses the procedure decomposition tree, the image assigned to the procedure node may be displayed. . This facilitates understanding of the contents of the procedure (action) by trying not only words but also associated images.

  Furthermore, if the apparatus according to the present invention is equipped with a camera having a photo (still image) or video (moving image) shooting function, or connected by wire or wirelessly, the camera is used in parallel with the ontology construction work. In addition to sequentially adding captured images to the database and using them as search targets, it is also possible to assign the images in association with procedure nodes.

[Example 6]
In this example, a configuration including a link generation unit and a warning generation unit in the ontology construction support apparatus according to the present invention described above will be described. The link generation means generates a link between designated nodes. The warning generation means issues a warning when the number of child nodes representing the partial procedure sequence based on one achievement method exceeds the set number with respect to the parent node representing the entire procedure.

  In this example device, when a link is generated between nodes to create a tree structure, the number of child nodes representing a partial procedure sequence based on one achievement method is smaller than the parent node representing the entire procedure. When the set number is exceeded, the warning generating means issues a warning. For example, when the set number of partial procedures (child nodes) is 5, as shown in FIG. 10, a procedure node representing six partial procedures based on one achievement method as compared to the procedure node 101 representing the entire procedure. When a link is generated (or is to be generated) with 102 to 107 as child nodes, a warning is issued. In FIG. 10, after a link is generated with the procedure nodes 102 to 106 representing five partial procedures as child nodes, a warning message 450 is displayed on the display means when attempting to generate a link with the sixth procedure node 107 as a child node. Is displayed to indicate a state where a warning is issued.

  Here, the number of partial procedures (child nodes) may be changed as appropriate. Further, the time when the warning is issued may be a time when a link is generated with a procedure node representing a partial procedure exceeding the set number as a child node, or any time after the link is generated.

  According to the apparatus of this example, when the number of child nodes representing the partial procedure sequence based on one achievement method exceeds the set number with respect to the parent node representing the entire procedure, the warning generating means issues a warning. Thus, the builder can be made aware of the hierarchy of procedure decomposition trees. As a specific method of issuing a warning, a warning by a sound such as a buzzer may be used in addition to the screen display of FIG.

[Example 7]
In this example, in the apparatus according to the sixth embodiment described above, a part based on one achievement method for a server connection unit that connects to a server that stores business information and a parent node that represents an overall procedure If the number of child nodes representing the procedure sequence exceeds the set number, the word representing each action given to two or more child nodes specified from the child node and the word of purpose or reason are ANDed in the server. A configuration provided with AND search display means for searching and displaying the search result on the display means will be described.

  For example, as shown in FIG. 10, when the number of child nodes representing a partial procedure sequence based on one achievement method exceeds the set number and issues a warning, the builder selects from among the child node group representing the partial procedure sequence. Two or more child nodes can be selected, and the server can search for each action given to the child nodes. Specifically, the server connection means accesses, for example, a server on an external network, and the AND search means indicates a word indicating each action given to two or more designated child nodes, and the purpose or reason. An AND search is performed on the word in the server. Then, the search result is displayed on the display means by the AND search means.

  According to the apparatus of this example, it is constructed by AND-searching a word representing each action given to two or more child nodes and a word of purpose or reason in the server, and displaying the search result. Can help people imagine and create superordinate concepts. Therefore, a partial procedure represented by two or more child nodes from the child node group can be made a high-level concept to deepen the hierarchy.
