The system uses pixel (像素)data in images and potentia y video — rather than just text — to locatedocuments. It learns to recognize the pixels associated with a search phrase bystudying the results from textbased image search engines. The knowledge gleaned (收集) from those results can then beapplied to other photos without tags or captions making for more accuratedocument search results.3.Over the last 30 years,says Associate Professor Lorenzo Torresani,a coauthor of the study,the Web has evolved from a small collection of mostly text documents to a modern,massive,fastgrowing multimedia data set,where nearly every page includes multiple pictures or videos. When a person looks at a Web page,he immediately gets the gist (主旨)of it by looking at the pictures in it. Yet,surprisingly,all existing popularsearch engines,such as Google or Bing,strip away the information contained inthe photos and use exclusively the text of Web pages to perform the documentretrieval. Our study is the first to show that modern machine vision systemsare accurate and efficient enough to make effective use of the informationcontained in image pixels to improve document search. researchers designed and tested a machine vision system — a type ofartificial intelligence that allows puters to learn without being explicitlyprogrammed — that extracts semantic (語義的) information from thepixels of photos in Web pages. This information is used to enrich thedescription of the HTML page used by search engines for document retrieval. Theresearchers tested their approach using more than 600 search queries (查詢)on a database of 50 million Web pages. They selected the textretheval searchengine with the best performance and modified it to make use of the additionalsemantic information extracted by their method from the pictures of the Webpages. They found that this produced a 30 percent improvement in precision overthe original search engine purely based on text.23. Paragraph 1 __D__24. Paragraph 2 __C__25. Paragraph 3 __E__26.
