The present invention is directed to a system, method and computer program for automatically extracting and mining relations and related entities from unstructured text. A method in accordance with an embodiment of the invention includes: extracting relations and related entities from unstructured text data, representing the extracted information into a graph, and manipulating the resulting graph to gain more insight into the information it contains. The extraction of relations and related entities is performed first by automatically inducting pattern and second by applying these induced patterns to unstructured text data. For each relation and entity, several features are extracted in order to build a graph whose nodes are entities and edges are relations.

Data monitoring means adds tag information representing a document conversion method to hyperlink information included in a hypertext type document sent to a user-side device from a server-side application, and sends to the user-side application the hyperlink information to which the tag information is added. When the tag information representing the document conversion method is included in a command to request retrieval which is sent from the user-side application, the data monitoring means converts the document sent from the server-side application as the results of the retrieval in accordance with the document conversion method represented by the tag information and sends the converted document to the user-side application.

To a multimedia information file including three-dimensional image data, three-dimensional display control information is added that indicates an intended three-dimensional display method for the three-dimensional image data or a data format in which the data is recorded. A three-dimensional image reproduction apparatus performs conversion appropriate for data characteristics derived from the three-dimensional display control information and then provides display. Recorded three-dimensional image data is thus given versatility so that the same three-dimensional image data can be used commonly to different three-dimensional display schemes.

In one aspect, the invention divides an audio signal into auditory events, each of which tends to be perceived as separate and distinct, by calculating the spectral content of successive time blocks of the audio signal (5-1), calculating the difference in spectral content between successive time blocks of the audio signal (5-2), and identifying an auditory event boundary as the boundary between successive time blocks when the difference in the spectral content between such successive time blocks exceeds a threshold (5-3). In another aspect, the invention generates a reduced-information representation of an audio signal by dividing an audio signal into auditory events, each of which tends to be perceived as separate and distinct, and formatting and storing information relating to the auditory events (5-4). Optionally, the invention may also assign a characteristic to one or more of the auditory events (5-5).

A method of redacting content from a document in electronic form includes the steps of selecting a geometric area on the document for redaction, representing the selected geometric area as one or more annotation objects, identifying information in the document representing content and location and nature of content, representing the identified information as one or more content objects, identifying content having the same geometric location as the annotation objects and creating a file with the identified content removed to produce a redacted document.

Provided is point-based efficient three-dimensional (3D) information representation from a color image that is obtained from a general Charge-Coupled Device (CCD)/Complementary Metal Oxide Semiconductor (CMOS) camera, and a depth image that is obtained from a depth camera. A 3D image processing method includes storing a depth image associated with an object as first data of a 3D data format, and storing a color image associated with the object as color image data of a 2D image format, independent of the first data.

The invention discloses a network text segmenting method based on the genetic algorithm, used for segmenting short network texts. The method comprises the following steps of: evaluating a Latent Dirichlet allocation (LDA) model corresponding to a corpus by using a Gibbs sampling method, inferring latent topic information using the model, representing texts by using the latent topic information; then transforming a text-segmenting process into a multi-target optimum process by using a parallel genetic algorithm, and calculating the coherency of segmented units, the divergence among the segmented units and fitness functions by using deeper semantic information; and carrying out the genetic iteration of the text segmenting process, and determining whether the segmenting process terminates based on the similarity among multi-iteration results or the upper limit of iterations to obtain the global optimal solution for segmenting the texts. Therefore, the invention improves the accuracy for segmenting the short network texts.
