【摘要】：隨著計(jì)算機(jī)的普及,文字輸入成了目前人與計(jì)算機(jī)交互的最重要的形式,決定著社會(huì)的信息化程度。中文輸入技術(shù)一直以來都是自然語言處理研究的熱點(diǎn)問題,而手機(jī)輸入法被稱作是移動(dòng)互聯(lián)時(shí)代“四大武器”(手機(jī)操作系統(tǒng)、手機(jī)瀏覽器、手機(jī)輸入法、搜索引擎)之一,同時(shí)也是移動(dòng)互聯(lián)網(wǎng)的三大入口(手機(jī)輸入法、手機(jī)瀏覽器、手機(jī)IM)之一,具有舉足輕重的戰(zhàn)略地位。優(yōu)秀的手機(jī)輸入法軟件不僅給用戶帶來良好的輸入體驗(yàn),而且還蘊(yùn)含著巨大的商機(jī)。隨著手機(jī)輸入法從傳統(tǒng)的依賴支付專利費(fèi)和使用許可費(fèi)的商業(yè)模式到依賴移動(dòng)互聯(lián)網(wǎng)運(yùn)營模式的轉(zhuǎn)變,手機(jī)輸入法領(lǐng)域由一個(gè)相對(duì)封閉的、壟斷的產(chǎn)業(yè)變成了一個(gè)開放的、競爭的平臺(tái)。隨著移動(dòng)互聯(lián)網(wǎng)大幕初開,各大互聯(lián)網(wǎng)公司紛紛爭奪這塊市場,但在移動(dòng)互聯(lián)網(wǎng)業(yè)務(wù)成熟之前,首先搶占移動(dòng)互聯(lián)網(wǎng)入口才是當(dāng)務(wù)之急。 隨著MTK MT6252芯片的推出,4兆R(shí)AM空間,4兆R(shí)OM空間的手機(jī),已經(jīng)占據(jù)了很大一部分市場份額,各大手機(jī)方案公司都已經(jīng)開啟了MTK MT6252的項(xiàng)目。為了滿足用戶的需求,公司決定對(duì)原有輸入法進(jìn)行了二次開發(fā)。對(duì)數(shù)據(jù)結(jié)構(gòu)和搜索算法進(jìn)行了重新設(shè)計(jì) 本文的主要工作和取得的成果如下： 1.調(diào)查研究輸入法軟件的發(fā)展歷史和研究現(xiàn)狀,了解當(dāng)前市場上主要手機(jī)輸入法軟件的特點(diǎn)。 2.結(jié)合MTK平臺(tái)特點(diǎn)和用戶需求,分析并制定輸入法軟件的詳細(xì)需求。 3.根據(jù)漢語拼音的特點(diǎn),設(shè)計(jì)相應(yīng)的字詞庫數(shù)據(jù)文件。 4.設(shè)計(jì)輸入法搜索算法 5.針對(duì)MTK平臺(tái)特點(diǎn)設(shè)計(jì)出合理架構(gòu),實(shí)現(xiàn)輸入法。 6.針對(duì)數(shù)據(jù)結(jié)構(gòu)和軟件架構(gòu)以及搜索算法的特點(diǎn),提出下一階段需要改進(jìn)和完善的地方。 本文通過調(diào)研當(dāng)前主流手機(jī)拼音輸入法的特點(diǎn),結(jié)合原有產(chǎn)品的技術(shù)實(shí)現(xiàn),詳細(xì)分析了系統(tǒng)需求,設(shè)計(jì)出合理的數(shù)據(jù)結(jié)構(gòu)以及基于此數(shù)據(jù)結(jié)構(gòu)的字詞搜索算法,最后基于MFC實(shí)現(xiàn)了由UI層,Shell層和Kernel層構(gòu)成的三層架構(gòu)體系的拼音輸入法軟件。
[Abstract]:With the popularization of computer, the input of characters has become the most important form of interaction between human and computer, which determines the information level of society. Chinese input technology has always been a hot issue in natural language processing, and mobile phone input method is called one of the "four weapons" (mobile phone operating system, mobile phone browser, mobile phone input method, search engine) in the era of mobile Internet. At the same time, it is also one of the three main entry points of mobile Internet (mobile input method, mobile browser, mobile phone IM), which plays an important strategic role. Excellent mobile phone input software not only brings users a good input experience, but also contains huge business opportunities. With the change of mobile phone input method from a traditional business model that relies on the payment of patent fees and the use of license fees to rely on the mobile Internet operation model, the mobile phone input method field has changed from a relatively closed, monopolized industry to an open one. A competitive platform. With the opening of the mobile Internet, the major Internet companies have been competing for this market, but before the mobile Internet business matures, it is the urgent task to seize the mobile Internet entrance first. With the introduction of MTK MT6252 chip, 4 megabyte RAM space, 4 megabyte rom space mobile phones, has occupied a large part of the market share, the major mobile phone solutions companies have started the MTK MT6252 project. In order to meet the needs of users, the company decided to carry out the secondary development of the original input method. The main work and achievements of this paper have been redesigned to the data structure and search algorithm as follows: 1. The development history and research status of the input method software are investigated, and the characteristics of the main mobile phone input method software in the current market are understood. 2. Combined with the characteristics of MTK platform and user requirements, the detailed requirements of the input method software are analyzed and worked out. 3. According to the characteristics of Chinese Pinyin, the corresponding word database data file is designed. 4. Design input method search algorithm 5. According to the characteristics of MTK platform, a reasonable structure is designed and the input method is realized. 6. In view of the characteristics of data structure, software architecture and search algorithm, the improvement and perfection in the next stage are put forward. By investigating the characteristics of the current mainstream Pinyin input method for mobile phones, combining with the technical realization of the original products, this paper analyzes the system requirements in detail, designs a reasonable data structure and a word search algorithm based on this data structure. Finally, the pinyin input method software is implemented based on MFC, which is composed of UI layer, Shell layer and Kernel layer.
