Publication number: 20130159920Abstract: An input method editor (IME) described herein couples scenarios of the input of the user with specific network services to offer more relevant and richer candidates for higher input productivity. Data relating to a computer application in which the input candidates are to be input and/or context relating to a user-submitted query is collected and analyzed to determine a scenario. The input candidates may include text candidates and rich candidates. The IME may select a scenario-tuned and type specific engine to identify the text candidates and/or rich candidates. The scenario-tuned text candidate engines leverage scenario-tuned language models and lexicons, and the scenario-tuned rich candidate engines leverage scenario-relevant web services, such as image, mapping, and video search, when available and appropriate.Type: ApplicationFiled: December 20, 2011Publication date: June 20, 2013Applicant: Microsoft CorporationInventors: Matthew Robert Scott, Huihua Hou, Weipeng Liu, Hao Wei, Chiwei Che, Byron Huntley Changuion, Weijian Xu, Xi Chen
