Abstract


With the rapid development of the field of smart phones, users of mobile Chinese input method growing demand. Currently, Sogou Pinyin input method cloud computing with a complete thesaurus and high accuracy rate, give the user a wealth of input experience, but it's the average number of keystrokes and re-rate is higher. Meanwhile existing defects surviving stroke input method, most stroke input method is based on the five basic strokes to achieve, using the search word and the radical expansion stroke input method and the Internet combined with real-time updates of hot words are not used in smart technology phone. Users prefer to be able to pass a minimum of strokes to get the most accurate word or phrase, especially the word internet hotspot. Therefore, the design and development of real-time access to Internet hotspots low weight code words and stroke input method as the main direction of the field of mobile intelligent. In this paper, the cloud of innovative ideas and MeeGo mobile operating system's high network performance, breaking strokes only search word and local lexicon restrictions, the most important thing is to request that the Web server hotspot thesaurus for word associations. This method improves the accuracy of word association, stroke input method to ensure the timeliness and ease of use, allowing users with richer input experience. I was responsible for six main part of the work: one involved in stroke input method needs analysis and design process; Second, participate in the completion of the Qt-based input method strokes some local features, functionality including strokes and radicals obtained through words or phrases and words get local association; Third, independently based on QML (Qt Meta-Object Language) all interface design and development, including the completion of the interface of the dynamic effects as well as stroke input method different angles of rotation and other functions; Fourth, the use signals and slots mechanism independently of Qt and QML client interface communication; five, independent design Web server, and the use of open source web crawler algorithm Heritrix crawl the web, using regular expressions to parse HtmlParser and get hot words and build vocabulary index ; six, independently based on REST (Representational State Transfer, Representational State Transfer) architecture HTTP protocol and XML data transmission Qt client and Web server. This system commissioning and formal operation, complete functions, running well, system stability, low failure rate, to meet the application needs of mobile phone users.
