Problems solved by technology

For user queries that cannot be described in one or more media expressions, searching and matching are performed between media information described in different types of media expressions, and only retrieve from a single media, which greatly reduces the accuracy of user retrieval. Failure to achieve cross-media information retrieval is the main problem that current information retrieval technology needs to solve

Abstract

The invention discloses a cross-media information retrieval system based on a mobile visual device, comprising: an image input module for inputting an image into the mobile visual device, a text input module for inputting text information related to the image , a text-based Internet image retrieval module for retrieving an image collection associated with the input text information and establishing a text-related image collection, for searching an image matching the input image in the text-related image collection, and Establish a content-based image retrieval module that generates visually relevant image sets and extract keywords from the web pages where the images in the visually relevant image sets are finally found, and then extract relevant online content and display the retrieval results. The first retrieval processing module . The invention combines text and image retrieval to realize accurate and fast cross-media and visual retrieval. The invention also discloses a cross-media information retrieval method based on the mobile visual device.

Description

Technical field [0001] The invention relates to the field of information retrieval, in particular to a cross-media information retrieval system and method based on mobile visual equipment. Background technique [0002] As retrieval technology becomes more and more popular, retrieval has gradually become a promising industry. For example, search engine providers make profits by attaching paid advertisements to the returned results, researching newer technologies, providing newer services, attracting more users and obtaining more advertising revenue. Now, this competition has shifted to the wireless field. Including traditional information retrieval, local information retrieval of neighboring stores and items, and even background image retrieval. [0003] Mobile retrieval based on mobile visual equipment is a brand new research topic driven by practical application requirements. With the improvement of people’s living standards and the continuous development of science and technol...
