The HDD 123 stores, for example, predetermined programs, various databases, processing results of the control unit 130, and the like.

  The control means 130 is composed of, for example, a CPU (Central Processing Unit) and the like, and controls the communication interface 111 and the storage means 120. The mode determination means 131, the schema registration mode management means 140, and structured data input Mode management means 150 and search mode management means 160 are provided. The mode discriminating unit 131, the schema registration mode managing unit 140, the structured data input mode managing unit 150, and the search mode managing unit 160 develop a predetermined program stored in the HDD 123 of the storage unit 120 in the RAM 122 by the CPU. It is realized by executing as above.

  The mode discriminating unit 131 discriminates which mode is selected from the schema registration mode, the structured data input mode, and the search mode as the control mode for the structured data storage unit 511, and determines the discrimination result. , The schema registration mode management unit 140, the structured data input mode management unit 150, and the search mode management unit 160 are notified.

  The schema registration mode management unit 140 includes an input data determination unit 141, a root node generation unit 142, a node generation unit 143, an attribute generation unit 144, a data type generation unit 145, a storage unit 146, and a reading unit 147. It has.

The input data determination unit 141 determines whether an arbitrary classification name of the schema of the structured data input in the schema registration mode matches the classification name of the schema stored in the structured data storage unit 511. Is.
When the input data discriminating means 141 discriminates that the inputted schema classification name already exists, the input data discriminating means 141 notifies the reading means 147 to that effect. On the other hand, when it is determined that the input schema classification name is unregistered, the input data determination unit 141 notifies the root node generation unit 142 accordingly. Although details will be described later, the input data determination unit 141 performs determination processing, selection processing, and the like related to schema registration based on data (child (child), attribute, data type, etc.) input after determination.

When the input schema classification name and the schema classification name stored in the structured data storage unit 511 do not match, the root node generation unit 142 sets the schema root having the input schema classification name as a node. Is generated as
Based on the presence or absence of the tree structure of the structured data input in the schema registration mode, the node generation unit 143 determines the branch of the node generated by the root node generation unit 142 when there is one or more tree structures.

The storage unit 146 stores the node associated with the attribute name and the type name in the structured data storage unit 511 as structured data.
When the classification name of the schema of the input structured data is stored in the structured data storage unit 511, the reading unit 147 reads the schema of the classification name, and the user terminal 6 via the communication interface 111. Is output.

  Here, new registration of a schema will be described with reference to FIGS. FIG. 5 is a diagram illustrating an example of a tree structure of a schema used for new registration, and FIG. 6 is a diagram illustrating a flow of registration of the schema illustrated in FIG. Here, it is assumed that the schema shown in FIG. 5 is registered. This tree structure has a root node 501, nodes 502, 503, 504, 505, and 506 in its branches (child), and nodes 507, 508, and 509 in the branches (child) of the node 504. Yes. The classification name of the newly registered schema is “literature information”.

  In this case, as shown in FIG. 6A, a root node 601 having this classification name “document information” is created. Then, as shown in FIG. 6B, a node 602 is created as one of the children. Here, the attribute name “title” is associated, but the data type is not input (null), and the node 602 is not completed. Then, as shown in FIG. 6C, the data type “string” is associated, the processing for this node is completed, and the node 603 is completed. Here, since there is no child for the node 603, as shown in FIG. 6D, a node 604 associated with the attribute name “isbn” and the data type “isbn” is created as the child next to the root node 601. Is done. The data type “isbn” is registered in advance. Then, as illustrated in FIG. 6E, a node 605 associated with the attribute name “author” is created. Since the child exists in the node 605, the data type “null” is associated therewith. Then, nodes 606, 607, and 608 representing three children are created for the node 605 by the method performed for the root node 601. Hereinafter, since it is the same, description is abbreviate | omitted.

Returning to FIG. 4, the description will be continued.
The structured data input mode management unit 150 inputs the structured data when the schema attribute of the structured data input in the structured data input mode is registered in the structured data storage unit 511. .

Specifically, the structured data input mode management unit 150 determines whether or not the combination of the input schema and the instance is valid, and inputs only valid ones. If it is not appropriate, a message to that effect may be displayed. Here, as a specific example of “valid”, a restaurant schema (attribute name = name, place, menu, impression, nearest station, parking lot) is assumed.
In this case, the appropriate ones are combination 1 (name = “Izakaya A”, place = “Yokosuka City”, impression = “very good”), combination 2 (name = “Western cuisine B”, place = “Yokosuka City” Hayama ”, impression =“ very delicious ”, parking =“ none ”).
On the other hand, combinations 3 (name = “Izakaya A”, place = “Yokosuka City”, private room = “Yes”), combination 4 (restaurant name = “Western cuisine B”, place = “Hayama, Yokosuka City”) ) Etc.

The search mode management unit 160 includes a search form display control unit 161, a schema search unit 162, and a search result output unit 163.
The search form display control means 161 controls the user terminal 6 to display a search form created in advance based on the schema classification name input in the search mode.

  Here, an example of the search form is shown in FIG. As shown in FIG. 7A, a search form for selecting one schema includes a plurality of items (genre, etc.). When the user selects the search symbol “or” on the right side of the “genre” input field, as shown in FIG. 7B, the input field is divided into two upper and lower parts, and two items at a time for one item. You can enter keywords. Each item is a search expression that is combined with a search symbol “and”. Although not shown, general buttons such as a search start button and a search end button are displayed on the search form. Moreover, it is not necessary to input in all the input fields.

The schema search unit 162 stores the structured data stored in the structured data storage unit 511 based on the schema search target including the classification name of the structured data and the attribute name of the structured data input in the search mode. Search data.
The schema search unit 162 determines whether or not the input schema search target is narrowed down. If there is a narrowing down, the narrowed search target is also searched.
The search result output means 163 outputs the searched result.

  Note that registration or search may be performed by inputting structured data from the input device M such as a keyboard or a mouse instead of the user terminal 6. In this case, the registration status and search results may be output to the output device D such as a liquid crystal display.

[Operation of application server]
The operation of the application server 10 shown in FIG. 4 will be described with reference to FIGS. 8 and 9 (see FIG. 4 as appropriate).

<Schema registration method>
FIG. 8 is a flowchart showing a schema registration method by the schema registration mode management means shown in FIG. The schema registration mode management unit 140 determines whether the schema classification name of the input structured data is stored (existing) in the structured data storage unit 511 by the input data determination unit 141 (step). S1: Input data discrimination step). If the classification name of the schema already exists (step S1: Yes), the schema registration mode management means 140 reads out and outputs the schema of the classification name by the reading means 147 (step S2), and ends the process. On the other hand, when the schema classification name is not registered (step S1: No), the schema registration mode management unit 140 uses the root node generation unit 142 to display the schema root having the input schema classification name as a node (root node). (Step S3: Route node generation step).

  Subsequently, the schema registration mode management means 140 determines whether or not a child in the tree structure is selected for the node to be processed (current node) by the input data determination means 141 (step S4). When a child is selected for the current node (step S4: Yes), the schema registration mode management unit 140 generates a new node as a child by the node generation unit 143 (step S5: node generation step). Then, the schema registration mode management unit 140 associates the attribute of the input structured data with the node generated in step S5 by the attribute generation unit 144 (step S6: attribute generation step). Next, the schema registration mode management unit 140 associates the type name of the structured data input by the data type generation unit 145 with the node generated in step S5 (step S7: data type generation step). Return to the discrimination process.

  If no child is selected for the current node in step S4 (step S4: No), the schema registration mode management means 140 determines whether or not the current node is a schema root by the input data determination means 141. (Step S8). When the current node is not a schema root (step S8: No), the schema registration mode management unit 140 selects, as the processing target, a node shifted by one step from the current node to the schema root side by the input data determination unit 141 (step S8). S9), the process returns to the determination process of step S4. On the other hand, when the current node is the schema root (step S8: Yes), the schema registration mode management unit 140 uses the node associated with the attribute name and the type name by the storage unit 146 as the structured data. Registration is made in the storage means 511 (step S10: storage step), and the process is terminated.

<Search method>
FIG. 9 is a flowchart showing a search method by the search mode management means shown in FIG. The search mode management unit 160 controls the search form display control unit 161 to display a search form created in advance on the user terminal 6 based on the input classification name of the schema (step S11). As a result, a search form corresponding to the schema is presented to the user of the user terminal 6 (see FIG. 1).

  Subsequently, the search mode management unit 160 searches the structured data stored in the structured data storage unit 511 based on the input schema search target by the schema search unit 162 (step S12: schema search step). . Then, the search mode management unit 160 outputs the search result by the search result output unit 163 (step S13: search result output step).

  Subsequently, the search mode management unit 160 determines whether or not the input schema search target is narrowed by the schema search unit 162 (step S14). When there is narrowing (step S14: Yes), the search mode management means 160 returns to step S12 and searches for the narrowed search target. On the other hand, when there is no narrowing down (step S14: No), the search mode management means 160 ends the process.

  Note that the application server (structured data processing apparatus) 10 can also be realized by executing a structured data processing program that causes a general computer to execute each step described above. These programs can be distributed via a communication line, or can be written on a recording medium such as a CD-ROM for distribution.

  According to the first embodiment, the application server 10 can register an unregistered arbitrary schema in the structured data storage unit 511 in the schema registration mode. In addition, the application server 10 reflects the schema input in the search mode and outputs a search result. Therefore, it is possible to improve the retrieval accuracy of the entry to be handled and to flexibly define structured data.

[Operation of application server]
The operation of the application server 10A shown in FIG. 10 will be described with reference to FIG. 11 (refer to FIG. 10 as appropriate). FIG. 11 is a flowchart showing a structured data input method by the structured data input mode management means shown in FIG.

  The structured data input mode management means 150A initializes the input data by setting the control variable i to “0” by the input form display control means 151 (step S21). Then, the structured data input mode management unit 150A controls the input form display control unit 151 to display the title input form on the user terminal 6 (step S22: input form display control step). Then, the structured data input mode management unit 150A determines whether data is input to the title input form by the error determination unit 152 (step S23). When data is not input (step S23: No), the structured data input mode management unit 150A ends the process. On the other hand, when data is input (step S23: Yes), the error determination unit 152 continues to determine whether there is a data type error in the combination of schema and instance of each structured data input to the input form. (Step S24: Error determination step).

  If there is a data type error in step S24 (step S24: Yes), the structured data input mode management means 150A causes the input error display control means 153 to display a message (error message) instructing re-input. Control is performed (step S25: input error display control step), and the process returns to step S23. On the other hand, if there is no data type error (step S24: No), the structured data input mode management unit 150A uses the input form display control unit 151 to input content based on the input title. Is displayed on the user terminal 6 (step S26).

  Then, the structured data input mode management means 150A determines whether or not a schema is selected from the schema list by the input form display control means 151 (step S27). When a schema is selected from the schema list (step S27: Yes), the structured data input mode management unit 150A causes the input form display control unit 151 to display an input form for the selected schema on the user terminal 6. (Step S28: input form display control step), the process proceeds to step S29. On the other hand, if no schema is selected from the schema list (step S27: No), the structured data input mode management unit 150A skips step S28 and proceeds to step S29.

  In step S29, the structured data input mode management unit 150A determines whether or not data is input to the schema input form by the error determination unit 152. When data is input (step S29: Yes), the error determination unit 152 continues to determine whether or not there is a data type error for the data input to the schema input form (step S30). : Error determination step). When there is a data type error (step S30: Yes), the structured data input mode management means 150A performs control to display an error message by the input error display control means 153 (step S31: input error display control step). Return to step S29. On the other hand, if there is no data type error (step S30: No), the input form display control means 151 adds "1" to the control variable i (step S32), and determines whether or not an end command has been input. (Step S33).

  In step S33, when the end command is not input (step S33: No), the structured data input mode management unit 150A returns to step S27. When an end command is input (step S33: Yes), the process proceeds to step S34. If no data is input in step S29 (step S29: No), the intermediate process is skipped and the process proceeds to step S34. In step S34 (entry display control step), the entry display control means 154 performs control to display a series of structured data input from the “1” to “i” -th as an entry on the user terminal 6, and performs processing. finish.

As shown in FIG. 14, the application server (structured data processing apparatus) 10B has the same configuration as the application server 10A shown in FIG. 10 except that the control means 130 includes an editor mode management means 170. The same components are denoted by the same reference numerals, and description thereof is omitted.

  The application server 10B further has an editor mode for editing the schema and instance of structured data as a control mode for the structured data storage unit 511, and the mode determination unit 131 also supports determination of the editor mode.

  The editor mode management unit 170 includes a schema editing control unit 171, an instance editing control unit 172, an editing schema determination unit 173, an editing error display control unit 174, and a data copy processing control unit 175.

The schema editing control means 171 controls to edit the schema based on an input indicating editing of the structured data schema in the editor mode.
The schema editing control unit 171 determines whether the schema of the structured data is selected or the instance is selected as the editing target in the editor mode, and when it is determined that the instance is selected, the subsequent control is the instance editing control unit. Hand over to 172.

The instance edit control unit 172 performs control to edit an instance based on an input indicating editing of the structured data instance in the editor mode.
The edit schema discriminating unit 173 stores the structured data stored in the structured data storage unit 511 and corresponding to the attribute of the schema before editing (hereinafter referred to as ITEMS). It is determined whether or not it corresponds to the attribute of (or is valid).
When it is determined that ITEMS does not correspond to the attribute of the edited schema (invalid), the editing schema determination unit 173 notifies the editing error display control unit 174 to that effect.

  When the editing error display control unit 174 is notified that the set of structured data (ITEMS) is not valid for the edited schema, the editing error display control unit 174 displays a message instructing the user to re-edit the edited schema. Control to be displayed on the terminal 6 (see FIG. 1) is performed.

  The data copy processing control unit 175 stores the schema or instance of the structured data stored in the structured data storage unit 511 in the storage unit 120 when the copy instruction is selected in editing the schema or instance of the structured data. Control is performed to temporarily store the data in the RAM 122 and paste the data to the designated position of the structured data stored in the structured data storage unit 511 in accordance with a paste (paste) command. Specifically, the user prepares a temporary temporary folder in the storage unit 120, for example, by the function of the data copy processing control unit 175, and stores an entry to be copied and structured data therein. Then, the user selects data to be copied from the temporary folder in the storage unit 120 and pastes it when constructing a new entry.

[Operation of application server]
The operation of the application server 10B shown in FIG. 14 will be described with reference to FIG. 15 (see FIG. 14 as appropriate). FIG. 15 is a flowchart showing a method of editing structured data by the editor mode management means shown in FIG.
The editor mode management unit 170 determines whether the schema of the structured data is selected as the editing target in the editor mode by the schema editing control unit 171 (step S41). When an instance of structured data is selected as an editing target (step S41: No), the editor mode management unit 170 determines whether there is an input indicating editing of the instance by the instance editing control unit 172 (step S41). S42).

  If there is no input indicating editing of the instance in step S42 (step S42: No), the editor mode management means 170 ends the process. On the other hand, when there is an input indicating editing of the instance (step S42: Yes), the editor mode management unit 170 performs control to edit the instance based on the input, depending on the instance editing control unit 172 (step S43). Then, the editor mode management unit 170 stores the structured data stored in the structured data storage unit 511 by the instance editing control unit 172 and valid for the schema before editing (current schema). The edited instance is added to the set (ITEMS) (step S44), and the process ends.

  When the schema of the structured data is selected as the editing target in step S41 (step S41: Yes), the editor mode management unit 170 determines whether or not there is an input indicating schema editing by the schema editing control unit 171. A determination is made (step S45). If there is no input indicating schema editing (step S45: No), the editor mode management means 170 ends the process. On the other hand, when there is an input indicating schema editing (step S45: Yes), the editor mode management unit 170 controls the schema editing control unit 171 to edit the schema based on the input (step S46: schema editing). Control step).

  Subsequently, the editor mode management unit 170 determines whether or not a set of structured data (ITEMS) that is valid for the current schema is valid for the schema edited by the schema editing control unit 171. (Step S47: Edit schema determination step). If ITEMS is valid for the edited schema (step S47: Yes), the editing error display control unit 174 ends the process. On the other hand, when the ITEMS is not appropriate for the edited schema (step S47: No), the editing error display control unit 174 causes the user terminal 6 to display a message instructing re-editing of the edited schema. Control is performed (step S48: edit error display control step), and the process returns to step S45.

  According to the third embodiment, the application server 10B can edit the schema freely defined by the user together with the instance in the editor mode. At that time, when the editing of the schema affects the instance, by instructing the user to re-edit the schema, the structured data storage unit 511 stores the appropriate structured data for the schema. It is possible to adopt only a set.
