摘要:
Disclosed is an apparatus and method for retrieving multimedia contents represented in a Moving Picture Experts Group (MPEG) 7 by transforming a user query into an MPEG-7 query format. The method for retrieving multimedia contents includes: representing a user query by using an indicator indicating a specific region of a Moving Picture Experts Group 7 (MPEG-7) document and a reference for referring to the indicator; analyzing a meaning of the user query represented by using the indicator and the reference to thereby produce an analysis result; and retrieving multimedia contents according to the analysis result. The present research can satisfy more than two retrieval conditions within the same structure in an MPEG-7 query format and it can also clearly represent that two different MPEG-7 documents are referred to. Since the meaning of a user query is analyzed accurately during retrieval process, it is possible to precisely retrieve multimedia contents.

Disclosed is an apparatus and method for expressing a query for searching multimedia data. The apparatus and method of the present invention expresses diverse query types in MPEG-7 query formats and uses field types to re use a designated region. The apparatus for expressing a query inputted from a user for multimedia data search includes: an input means for receiving a query for multimedia data search from a user; and a query expression means for expressing the input query in a field type, wherein the field type includes at least one among identifier information indicating identification (ID) information of a field presenting a search condition included in the input query; type information indicating data type information of the field; and reference information indicating identifier information of another field for reference. The present invention is applied to MPEG-7 query formats.

Provides is an apparatus for question answering based on answer trustworthiness including: an answer indexer that indexes documents of which document trustworthiness satisfying a threshold value among documents included in a document collection and stores it in a knowledge Bases; an answer candidate extractor that extracts answer candidate documents for a user's question from the knowledge Bases; an answer source trustworthiness measurement unit; an answer extraction strategy trustworthiness measurement unit; and a trustworthiness integrator that generates an answer candidate trustworthiness list by ranking the answer candidate documents on the basis of the document trustworthiness, the source trustworthiness, and the extraction strategy trustworthiness of the answer candidate documents.
摘要:
The present invention relates generally to a voice-based mobile search apparatus and method, and, more particularly, to a voice-based mobile search apparatus and method, which can present optimized search results suitable for a mobile status while allowing a user to conveniently use a search service in a mobile environment. The voice-based mobile search apparatus according to the present invention includes a voice recognition unit for recognizing a user's voice transferred through a mobile terminal and then receiving a query. A status information collection unit collects status information of the mobile terminal and profile information of the user. An answer search unit searches a knowledge base based on the query, and extracts short answers matching the query. An answer provision unit processes the short answers in conformity with the status information of the mobile terminal and the profile information of the user, and provides the processed short answers.
