Embodiment Construction

[0047] figure 1 A schematic diagram of a system 101 for identifying a particular image in a database 104 is shown. Although the embodiment is described for a database comprising images, the system can also be used to identify specific data objects having other data types. For example, a three-dimensional representation of an object or environment, a video clip or an audio clip.

[0048] The system includes a query construction unit 102 that constructs search queries. A search query expresses user intent about a particular image; it expresses what type of image the user is looking for. System 101 uses a search query to identify candidate images, which are candidates for a particular image. Build a search query based on user input. Users provide sample images for building search queries. In another embodiment, it is possible for the user to provide keywords describing the content of the images he wants the system to recognize.

[0049] The query construction unit 102 const...

Abstract

The invention relates to a method, a system (101) and a computer program product to identify a particular data object of a data type in a database (104) that comprises data objects of the data type. The system (101) comprises a query composition unit (102) to compose a search query to identify a candidate data object being a candidate for the particular data object. A search unit (103) identifies the candidate data object in the database (104) based on the search query. A presentation unit (105) presents the candidate data object to the user. A feedback receiving unit (106) receives user feedback on the relevance or irrelevance of a segment of the candidate data object. The search unit (103) further identifies an improved candidate data object in response to the received user feedback. The improved candidate data object is an improved candidate for the particular data object.

Description

technical field [0001] The present invention relates to the field of information retrieval, and more particularly, to the field of systems, methods and computer program products for identifying specific data objects of a data type in a database comprising data objects of that data type. Background technique [0002] An information retrieval system searches databases to retrieve the information a user is looking for. In information retrieval systems, the biggest challenge is understanding user needs. Keyword-based search systems are often limited in query language and database indexing. For users, it is difficult to express exactly what he is looking for with keywords. Information retrieval in image-based databases is even more difficult because it is difficult for systems to interpret images in the same way as humans. A successful paradigm for solving this problem is "Relevance Feedback". The system retrieves candidate data objects that match the search query, a user rev...
