Abstract: A system retrieves structured documents based on first desired concept item having first concept items classified hierarchically and subordinated to first desired concept item, second desired concept item having second concept items classified hierarchically and subordinated to second desired concept item, generates a table displaying retrieval results, and associates groups of desired component, one of first items classified as first concept items immediately lower than first desired concept item, and desired second concept item with column index cells of table respectively. When a display area where one of the column index cells is displayed is designated, the system acquire the groups associated with the designated area, and retrieves, based on the acquired group, structured documents each including the desired component including a value in which one of the first concept items subordinated to the one of the first item and one of the second concept items are included.

Abstract: A structured data retrieval apparatus stores, in a first memory, a plurality of template IDs used to identify locations of a plurality of structure elements included in a hierarchical structure, stores, in a second memory, a plurality of structured data items each of which includes a plurality of elements, each of the elements being assigned a template ID of one of the structure elements, inputs a retrieval condition which designates a first structure element of the structure elements, and a character string included in the first structure element, retrieves, from the structured data items, a structured data item including a first element which includes the character string and is assigned a first template ID of the first structure element, and outputs the structured data item retrieved.

Abstract: When a retrieval condition including a first desired word and a first desired component including a value in which the first desired word is included, is inputted, a first detecting device detects second desired components each being similar to the first desired component, an acquiring device acquirers second desired words each being similar to the first desired word, a first retrieving device retrieves first structured documents each including a first component including a value in which one of the first desired word and the second desired words is included, a second retrieving device retrieves second structured documents each including a second component corresponding to one of the first desired component and the second desired components and including or corresponding to the first component.

Abstract: A digital content management apparatus is capable of collectively displaying a list of content present on a network in an easy-to-use way. A content management server determines whether identical content is present when creating a display list of content managed by plural, different a audio video devices connected to the network. When identical content is present, the server creates a display list such that identical content is displayed according to designated conditions, such as in order of transmission speed of servers, based on a setting file.

Abstract: A content information management apparatus includes a collection processing unit which collects content information items indicating attributes of contents stored in different specific forms in storage devices connected to networks using different protocols, a conversion processing unit which converts each of the content information items collected by the collection processing unit into content information of a standardized form, and a display which displays the content information.

Abstract: When a retrieval condition including a first desired word and a first desired component including a value in which the first desired word is included, is inputted, a first detecting device detects second desired components each being similar to the first desired component, an acquiring device acquirers second desired words each being similar to the first desired word, a first retrieving device retrieves first structured documents each including a first component including a value in which one of the first desired word and the second desired words is included, a second retrieving device retrieves second structured documents each including a second component corresponding to one of the first desired component and the second desired components and including or corresponding to the first component.
