The Design And Realization Of MeeGo Mobile OS Input Method Based On Stroke

With the popularity of intelligent mobile, user requirements of mobile Chinese input method are rapidly increasing. Sougo pinyin input method has brought most users rich experience based on the excellent vocabularies at present, but the relative stroke input method still has some defects with only five basical strokes. Using extended radicals to find words and communicating with Internet hot words have not be applied to mobile. However, users just expect to use less strokes or radicals to obtain suitable characters and phrases, especially Internet hot words. So develop the stroke input method that can get Internet hot words and low coincident code rate will become the main target.This paper solves the problem with the innovation of extended radicals and cloud computing concept relied on high network performance of MeeGo, breakthroughs the limitation of local vocabularies, what's important, mobile client can get hot associational words through requesting the dictionaries of Web server. This method can improve the assuracy of associational words, guarantee the timeliness and usability for the input method, and enrich user's input experience. The author in this paper is responsible for the following tasks:Firstly, participate in the whole process of requiment analysis and design; Secondly, develop main functions for local stroke input method based on Qt including getting local characters and associational words; Thirdly, design and develop independently the whole UI in QML, including the dynamic effection and circumrotation of different angles; Fourthly, complete the communication of Qt client and QML UI with signal/slot; Fifthly, design independently web server, use Heritrix to crawl web page and build dictionaries index with HtmlParser and regex expression; Sixthly, complete independently the transinformation for mobile client and Web server with HTTP of REST and XML.In the simulating and formal running process, this system has the integrate function, high stability and low error rate, it can satisfy the need of most mobile users.
