Description

  The present invention relates to a content management apparatus, method, and program, and more particularly, to a content management apparatus, method, and program for assigning and managing content with a label.

  With the spread of digitized content and the increase in capacity of file systems, it is possible to store a large amount of content individually. However, at the present time, the system for storing and managing is not functioning sufficiently when the accumulated content is reused.

  Conventionally, there is a full-text search system as a system for managing content. In the full-text search system, it is possible to create an index for all the character elements in the management content and perform a high-speed search. There is a system for automatically indexing contents stored in a computer and performing a search (see, for example, Non-Patent Document 1).

As a system for managing content, there is a file system with attributes. It becomes easy to specify content by using metadata with attributes (see, for example, Non-Patent Document 2).
http: //desktop.google,com/en/features.html. "Development of a Semantic file System for Managing Large Document Spaces." The IEICE Technical Report, DE, Data Engineering, Vol.106, No. 150 (20060707) pp. 139-144, DE2006-115 The Institute of Electronics, Information and Communication Engineers ISSN: 09135685

  However, the above-described full-text search system cannot be used for organizing content by using a process for searching (identifying) content.

  In addition, in the file system with attributes, it is easy to specify the content, but when viewed from the viewpoint of adding metadata, it is necessary to manually add them one by one, which is difficult to organize, There is a problem that the organization cost increases.

  The present invention has been made in view of the above points, and a content management apparatus and method capable of minimizing the total value of content organizing cost and specific cost and adding a label string to the content in a few steps And to provide a program.

  FIG. 4 is a flowchart of the overall outline operation in one embodiment of the present invention.

  The content management apparatus 100 uses the flow A (content from outside) based on information such as a command, a selected node, a selected content ID or an input content entity, a destination node name, or a newly created node name input from the user terminal 200. Input flow), flow B (content copy flow in the tree), flow C (content deletion flow in the tree), flow D (node creation flow in the tree), flow E (node copy flow in the tree), flow F (Node deletion flow in the tree) is performed, and when any of these processes is completed, the flow G is performed.

[Flow A]
First, the “content input operation” of flow A in the content input unit 161 will be described.

  FIG. 5 is a flowchart of an external content input operation according to the embodiment of the present invention.

  Step 110) When the content and the node name (selected node) selected by the user are input from the user terminal 200 via the input / output unit 110 from the user terminal 200, the content input unit 161 uses a hash or the like for each content. And a content ID list is generated.

  Step 120) The content input unit 161 associates the content entity with the content ID generated for each content in step 110 and writes it in the content storage unit 150.

  Step 130) It is determined whether or not the writing of the content body has succeeded. If the writing has succeeded, the process proceeds to Step 140. If the writing has failed, the process ends.

  Step 140) The content input unit 160 converts the acquired selection node into a label ID, refers to the tree storage unit 120 based on the label ID, and the input selection node is “root” (parent node). If it is “root”, the process is terminated. If it is not “root”, it is assumed that there is an upper node in the selected node, and the process proceeds to step 150. A hash, a suffix tree, or the like can be used for conversion from a node (node name) to a label ID.

  Step 150) The content input unit 160 acquires the label ID of the upper node of the selected node from the tree storage unit 120.

  Step 160) The content ID of the input content and the label ID of the upper node are written in the label ID / content ID storage unit 140.

[Flow B]
Next, the operation of “content copy in tree” in flow B in the content copy unit 162 will be described.

  FIG. 6 is a flowchart of content copying in a tree according to an embodiment of the present invention.

Based on the label ID of the selected node, a set of child nodes of the selected node (label ID list of the child node) is read from the tree storage unit 120, and matches the label ID of the creation node input in the child node label ID list Check if there is something to do. If there is a match, the process ends. If not, the process proceeds to step 420.

  Step 420) If no child node matches the label ID of the creation node in Step 410, the label ID of the creation node is registered in the tree storage unit 120.

  Step 430) It is determined whether or not the label ID of the created node is registered in the label storage unit 130. If registered, the process ends. If not registered, the process proceeds to Step 440. To do.

  Step 440) The node creation unit 164 registers the input creation node name as a label and a pair with a label ID corresponding to the node name.

[Flow E]
Next, “node copy in tree” of flow E in the node copy unit 164 will be described. This process is a process of copying a node registered in the tree storage unit 120 to another node.

  Step 510) When the content ID, the selected node name (selected node), and the destination node name (destination node) are input from the user terminal 200 via the input / output unit 110, the node copy unit 164 The destination node name is converted into a label ID, and a “destination label ID list” composed of the input content ID and the destination label ID is generated. Further, based on the label ID of the destination node, the tree storage unit 120 is referred to and the label ID of the upper node of the destination node is acquired.

  Step 511) Based on the label ID of the selected node, the label ID / content ID storage unit 140 is referred to, and the content ID narrowed down by the label ID of the selected node and the label ID of the upper node is acquired.

  Step 515) The label ID is acquired from the label ID / content ID storage unit 140 using the content ID designated by the user as a key, and a “current label ID list” including the content ID and the label ID is generated.

  Step 520) The duplicate of the “destination label ID list” generated in step 510 and the “current label ID list” is deleted and merged.

  Step 530) In step 520, the content ID and label ID of the merged label ID list are written in the label ID / content ID storage unit 140.

  Step 540) New node creation processing (node creation processing in FIG. 8) is performed with the selected node as the parent node and the destination node as the child node, and the label ID of the new node is written in the tree storage unit 120.

  Step 550) Replace the selected node with the destination node. Specifically, the label ID of the destination node in the tree storage unit 120 is rewritten to the label ID of the selected node.
