Abstract: A game apparatus includes an LCD, and a touch panel is provided in relation to the LCD. The LCD displays a game screen, and the player performs touch operations (sliding, click, etc.) on the touch panel with use of a stick to draw, correct and decide at random a moving path of an object. When the movement path of the object is decided and some point on the movement path is clicked, the object moves to the clicked position according to the movement path.

Abstract: An information processing apparatus includes a touch panel provided on a menu selection screen including a plurality of items, a direction key for instructing a moving direction of a cursor, and an execution key for instructing execution of a process corresponding to a selecting item. The display of the cursor can be moved according to a position instructed by the touch panel as well as the direction key. A process corresponding to a selected item is executed by a touch-off as well as by an operation of the execution key.

Abstract: A document processing apparatus according to the present embodiment handles a structured document file described in XML, XHTML, and HTML, etc., as a document to be processed. The document processing apparatus selects a base tag and a comparison tag from a structured document file, and computes a positional proximity between the two tags in a hierarchical structure as a tag-proximity degree. The apparatus specifies a comparison tag with a tag-proximity degree of a predetermined threshold value or more with respect to the base tag, as a proximity-tag. The apparatus outputs the data specified by one or more of the proximity-tags, as the proximity-data with respect to the base tag.

Abstract: The present invention relates to a document retrieval apparatus for retrieving the desired data from a structured a document file. The apparatus holds index information in which a tag set including tags that are in a hierarchical relation with each other, is associated with one or more of positions of which path expressions include the tag set, in a structured document file. When receiving an input of a partial path expression, the apparatus specifies a position where the tag set included in the partial path expression is present as part of a path expression of the position, as a candidate position for a position to be retrieved, with reference to the index information.

Abstract: In registering a new document file in an index, the accumulated percentage of the number of registered keys A from registered keys associated with one posting data, including registered data, is computed. The posting data of a registered key associated with the number of posting data items, which is at most a threshold N, is stored in a leaf page of a balanced-plus tree constituted of the registered keys, and the posting data of a registered key associated with the number of posting data items, which is greater than the threshold N, is stored in a page of a posting-storing unit. When the accumulated number i of registered documents is a predetermined document number, the threshold N of the number of posting data items is changed to the maximum number of the posting data items that are associated with a registered key where the accumulated percentage is less than 60 percent.

Abstract: The present invention relates to a document search apparatus for searching a predetermined corpus for a document file whose content is related to text for searching. The apparatus stores index information that indicates the position in a document and the position in a morpheme for a respective gram. Upon the receipt of the input of text for searching, from a user, the document search apparatus extracts a morpheme and a gram. Then, upon the indexing of the rarity of the morpheme in the corpus and the detection of a document file that contains the morpheme, the number of times such a morpheme appears in the document file is counted as an appearance frequency. From the estimate number and the appearance frequency regarding the morpheme, the relevance of the contents between the text for searching and the document file is indexed as a relevance score.

Abstract: A document retrieval apparatus holds: index information in which data and an entity document are associated, with respect to a group of entity documents that are XML documents including entity information; and index information in which data and an annotation document are associated, with respect to a group of annotation documents including annotation information that corresponds to the entity information, respectively. Upon receiving an input of a retrieval query including the entity data for retrieval and the annotation data for retrieval, the document retrieval apparatus at first specifies an entity document including the entity data for retrieval. Further, the document retrieval apparatus specifies an annotation document including the annotation data for retrieval, and specifies an entity document corresponding to the specified annotation document.

Abstract: A table structure analyzing apparatus extracts first row data and second row data in table data. Similarity between the data is computed based on Levenshtein distance or the number of characters. Further, similarity between the first row and the second row as a whole is determined. When the similarity is equal or less than a predetermined threshold value, it is determined that the boundary between the first and second rows is the boundary between a header part and a substantive part. A similar determination is made in the direction of columns.

Abstract: A structured document file in similarity relation is specified based on a tag structure of a structured document file. A node-pair detection unit detects from a structured file a tag pair having a predetermined positional relation as a node pair. An attribute-value acquisition unit indexes as an attribute value the appearance mode of a node pair in a structured document file. An index-information creation unit creates index information associating a node pair and an attribute value thereof. A common-pair detection unit detects as a common pair a node pair that is common in a query document, which is a structured document file, and in a document to be examined, which is a structured document file to be compared.
