3、整输入。对于输入法系统的字词库排序问题,本文给出一种统计语言模型进行实现,并设计出针对该模型的笔画码转换流程。为了更适应用户输入的需求,本输入法系统增加了自学习模块与基于N元语言模型的智能词输入方法,使得用户在使用过程中,越来越符合用户输入的习惯。在手机智能输入法实现中,由于输入法管理器-编辑器(IMM-IME)结构是Windows Mobile系统多语言支持的核心组件之一,为输入法接口的实现提供支持。本文重点讨论在Windows Mobile系统下汉字输入法的基本工作原理,详细分析了基于IMM-IME结构的手机输入法的构成、工作过程及实现中所涉及到一些关键问题,为输入法的实现提供良好的技术支
4、持。然后讨论输入法在实现过程中所涉及到的一些技术问题,并给出智能输入法运行流程及最终实现结果。本文的手机智能输入法的特点是能够实现词组及语句的输入,且操作简单,易学易用,使得用户很容易上手且输入效率高。同时,该输入法增加了自学习模块,可以在用户使用过程中自然学习用户常输入的词组及语句,提高汉字输入速度与智能程度。为进一步减少用户选择及数字键盘输入的平均码长,本文采用二元组通过基于前次输入汉字方式来实现汉字智能词输入,减少了用户文字选择,提高中文输入的效率。最终研究表明将这些模块应用于Windows Mobile平台下手机智能输入法具有重要的实用意义。【英文摘要】At present, with
