Zha says both patents were developed when he worked for Inktomi Corporation which was later acquired by Yahoo! Inc. Zha was one of the five brightest computer scientists locked inside a laboratory for 18 months to devise a solution to one of the web\u0027s most frustrating problems: irrelevant search results.\u00a0In June of 1999, the team emerged with a solution which has earned Zha the following two patents:\u003C\/p\u003E\n\u003Cp\u003EU.S. patent 7028027 titled \u003Cem\u003EAssociating documents with classifications and ranking documents based on classification weights\u003C\/em\u003E develops search engine ranking algorithms that deliver relevant documents based on the regions that the users belong to (region is a concept that is similar to country but is more refined), as well as algorithms for identifying the regions of web documents.\u003C\/p\u003E\n\u003Cp\u003EU.S. patent 6990628 titled \u003Cem\u003EMethod and apparatus for measuring similarity among electronic documents \u003C\/em\u003Edescribes algorithms for measuring the similarity among web documents by utilizing the textual contents, hyperlink structures, and click-through patterns.\u003C\/p\u003E\n\u003Cp\u003ETo read an article related to this technology\u2019s\u00a0development, \u003Ca href=\u0022http:\/\/sanfrancisco.bizjournals.com\/sanfrancisco\/stories\/1999\/06\/21\/story3.html\u0022 target=\u0022_blank\u0022\u003Eclick here\u003C\/a\u003E.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EComputational Science and Engineering Professor Hongyuan Zha was recently awarded two U.S. patents for technology behind the Yahoo!
