There is disclosed an interface enabling easy implementation of processing on hierarchical data, and a method facilitating comprehension of the structure, meaning, and format of hierarchical data. There is also disclosed a data processing device including a user interface portion receiving data with tuples each a combination of data of different types, and lists each a series of data of a same type, display data obtained by converting the data, and an instruction requesting processing from a user, and presenting the display data, data managing portion managing the hierarchical data, display-data generating portion generating the display data from the hierarchical data, and analyzing portion implementing the processing. Data is presented in a table format having rows displaying level names and attribute names, respectively. The generating portion samples data of each level of hierarchical data to extract an amount possible to present, and converts the data format.

Data processing device

An image retrieval system, including: an image input section for inputting a retrieval target image; an image data base for storing image data; a retrieval section for retrieving a plurality of images similar to said retrieval target image, by using a feature amount of said retrieval target image from said image data base; a filtering processing section for carrying out filtering processing using a whole image feature amount of another feature amount different from said feature amount of said retrieval target image about said plurality of images, to obtain a filtering result; and an outputting section for outputting said filtering result.

Human image retrieval system

In a similar face retrieval system for retrieving an image photographing a face similar to a face detected from a retrieval query image from a retrieval target image group by using an image photographing a human face as the retrieval query image, whole image features as features representative of background information are extracted from each whole area of an each image of a retrieval target image group, to calculate a degree of similarity through comparison with each set of whole image features, and an image having a degree of similarity not lower than a certain value and having a lower retrieval result order from retrieval results. It is possible to efficiently retrieve the same person playing in different scenes by utilizing different features for a retrieval process and a filtering process.

For hierarchical data including tuples each including a combination of different data types and lists each listing data of a same data type, corresponding attribute-based data divided by attribute is stored in attribute-based files whereas information on the structure of the hierarchical data is held as schema information. The schema information includes data type information on the hierarchical data structure, including data type information on each element of each tuple and data type information on only a top element of each list. The attribute-based files storing the attribute-based data are managed to be in order by a file name management table. Data on each attribute is stored in a file in a state of being hierarchized in a list format corresponding to the depth at which the each attribute is listed in the schema information. When performing analysis processing: a required attribute is specified; files of only the specified attribute are opened; the initial data structure is restored using the schema information; and data analysis processing is performed.

Data processing device and method

To allow a user to use an appropriate search engine, this invention provides a computer system including: a client computer; a search engine; and a management computer, in which the management computer is configured to: collect logs of access; specify a parameter transferred from the client computer to an access destination of the client computer by analyzing the collected logs of access; judge that an access including a parameter judged as a search query is an access to the search engine; select a log of access to the search engine from the collected logs of access; extract an address of the search engine and the search query from the selected log of access to the search engine; and store a correspondence between the extracted address of the search engine and the extracted search query in a search engine profile.

Method of retrieving an appropriate search engine

A data item name constituting a source data schema is extracted (), a data item name constituting a target data schema is extracted (), element concepts included in the extracted data item names of the source data schema and the target data schema are extracted (), a distinctive relation between the data item names is set based on the extracted element concepts to be stored in an ontology (), the data item names of the source data schema and the target data schema are read, a correlation is set between the two read data item names based on the distinctive relation to be stored in a mapping definition file ().

Cross lingual text classification apparatus and method

An information processing apparatus connected to a network to translate a document using a translation knowledge cost-effectively is provided with a dictionary; an inquiry device for transmitting, during a time translating a sentence written in a first language, an inquiry for inquiring the translation knowledge for translating a syntactic unit of the sentence written in the first language containing an unknown word and a correct grammar to the network, after translating other words of the sentence into a second language, when the unknown word that cannot be translated into the second language is recognized during translation of the document; and a translation device for estimating a part of speech for the unknown word to apply a hypothesis-setting rule during translation of the sentence, and for continuing translation of a syntax following the syntactic unit of the sentence, wherein the syntactic unit is translated by using an answer to replace the translation of the sentence when the answer to the inquiry is received.

Dictionary management method and apparatus

To automatically generate translation templates containing variables which can be replaced with various words or phrases from a bilingual pair of sentences, the machine translation system reads the first language sentence and second language sentence which are mutually equivalent, analyzes the morphemes and phrases of the sentences, identifies the word correspondence between the first language sentence and the second language sentence with reference to the bilingual dictionary, generates a translation template by replacing the corresponding words of the first language sentence and second language sentence with variables which are mutually correspondent, extracts the phrase correspondence between the first language sentence and the second language sentence, generates a generalized template wherein the corresponding phrases are replaced with variables, and generates a partial template wherein the corresponding phrases are separated. By doing this, a translation template can be learned (automatically generated) from bilingual pair of sentences, and high quality translation can be obtained.

System and method for automatically generating translation templates

A pre-edit support method for a machine translation system has an improved accuracy of parsing and an improved efficiency of pre-edit support. In a machine translation system translating a source language into a target language, a source language text is read and divided into words. Word sequences occurring a plurality of times are extracted, of the extracted word sequences the word sequences having a high occurrence frequency or a large number/high ratio of words with multiple parts of speech, are extracted as complex word candidates and displayed to a user, of the complex word candidates the complex word candidates the user designates are used as complex words to be translated integrally, and pre-edit symbols are added to the integral complex words as translation support information.

Pre-edit support method and apparatus

A method and an apparatus for extracting text information for use with a computer system including an input unit, an output unit, and a storage is described. The storage is loaded with documents, abstracts thereof, and relational information indicating relationships between a sentence of the abstracts and sentences of the documents. In response to a selection instruction from the input unit, a sentence is selected from the abstracts such that the documents are accessed so as to extract therefrom, based on the relational information, sentences associated with the selected abstract sentence. Information related to the associated sentences thus extracted is outputted to the output unit. According to the method and the apparatus, text information such as important portions of a document and a list of words appearing in the important portions can be easily obtained by use of the abstracts.
