Description

Hand-held wireless communication terminal Tibetan input method based on syllable word

Technical field:

The Tibetan language processing technology field.

Background technology:

Tibetan language is to gulp down Mi Sangbuzha with reference to Sanskrit initiative at that time by 7 th Century.Belong to alphabetic writing, constitute by the letter of 30 voiced consonants and the symbol of 4 expression vowels.Written word and modern spoken language have some distances.Write across the page from left to right.Pronunciation and various places dialect have corresponding rule, and various places all can combine into syllables, hide the common written the vehicle of communication that uses so can become.Once write and translated a large amount of books in history with Tibetan language, development has played significant role to Tibetan culture.

Tibetan language is walked crosswise from left to right and is write, but letter not exclusively is to arrange by linear mode, and the part complex consonant adopts the folded up and down method representation of writing of letter.Therefore, traditional Tibetan language word syntax can be divided into " basic word ", " upper word adding ", " down word adding ", " pre-script ", " back word adding " and " heavy back word adding " according to the locations of structures of letter in syllable word.Wherein upper word adding and down word adding are added on the above and below of basic word respectively, and pre-script and back word adding are arranged in the front and back of basic word respectively, and heavy back word adding writes on the back of back word adding.The classification that vowel is looked in the position of vowel sign be added on respectively basic word or upper word adding top (i, e, o), and following (u) of basic word or down word adding.A vowel in the ancient in addition Tibetan language is not provided with letter symbol, contains without exception in the basic character pronunciation with other vowel signs not.Because the consonant of Tibetan language can independently be write, a therefore independent consonant necessarily contains vowel a when constituting a Tibetan language word (syllable word), and constitutes the form of a readable complete Tibetan language word of writing.

Illustrate two kinds of structures (referring to accompanying drawing 2) of Tibetan language syllable word below

In the accompanying drawing 2, " base "=" basic word ", " on "=" upper word adding ", D score=" down word adding ", " preceding "=" pre-script ", " back "=" back word adding " and " heavy back word adding ", " unit "=" vowel sign ".Digital watch is shown with what consonants or vowel sign can serve as the letter or the symbol of this position.It should be noted that in this structure other positions can be the rooms except basic word.The top or the ground end of file in the drawings appear in the vowel character, but on each Tibetan language syllable word file a vowel character can only be arranged.

For example:

bskjims

Bonding, amalgamation

Generally, pre-script, back word adding and heavy back word adding all are single forms, can not add other characters more up and down.But also have a kind of specific forms in the Tibetan language on the back word adding position, comprise empty word etc., so just formed the structure of another Tibetan language word, referring to accompanying drawing 3.

For example:

sprefiu

Monkey

Though written Tibetan language has only 30 consonants and 4 vowel signs to form, but it is individual surplus about 220 of single consonant of the ancient Tibetan language of the reflection of forming by basic word, pre-script, upper word adding, down word adding and the consonant cluster initial consonant, the simple or compound vowel of a Chinese syllable of forming by vowel sign and back word adding and heavy back word adding about 90.

The Tibetan language input and output research early start of desktop system adopts dot matrix word library to realize in the DOS system in the eighties in last century.Thereafter, along with the development of operating system, the Tibetan language input and output are also in continuous progress and development.At present, on windows platform, adopt plug-in mode to realize mostly, can realize functions such as the input of Tibetan language ground, word processing more easily, what be worth special proposition is upright Tibetan language composing system, this software can support the Tibetan language of different fonts, font size and handle, and has very strong functions.On the (SuSE) Linux OS platform, the domestic easy-to-use cross-platform Tibetan language information handling system of convenience of also successfully having developed based on Linux.But because these softwares come from different software development manufacturers, adopt different ISN standards, cause the compatible non-constant between the different software, for this reason, domestic, repeatedly study the information processing code (IPC) of Tibetan language in the world, and owing to worked out and finish " infotech-Tibetan code character set expansion sets A national standard " in 2004.

We can say, be in various software and deposit and progressively move towards standard and the unified later stage period of the Warring States at desktop system Tibetan language at present.But, on embedded systems such as mobile phone, then be in blank and starting stage substantially.

Summary of the invention:

Along with strategy to develop western regions is implemented, informatization is attached great importance in western each province and city, makes every effort to drive the great-leap-forward development of other industry by informationalized developing in advance.At present Tibet Autonomous Region realizes the long-range objectives of " the county county lead to optical cable, takes on the telephone in the every country ", builds up the communication network that the optical fiber of the covering whole district combines with satellite substantially.A collection of various information service platforms towards the public build up in succession, make the various information resource obtain integrating and utilize.Most of key city in Tibet has become the ingredient that people work and live by the network delivery and the information of obtaining.All kinds of cellphone subscriber's quantity straight lines of each Tibetan area of China rose in recent years, more and more the vast agriculture and animal husbandry all kinds of wireless terminal holders in area especially, the common people are increasing to the demand of communication, and the cry of the Tibetan languageization of communication facilities and various types of communication platform is also more and more higher.But, up to the present, also support the input and output of Tibetan language without any a mobile phone.Therefore, to have the wireless terminal and the handheld device of certain Tibetan language demonstration, input, transmitting function extremely urgent in exploitation.In addition, this project develops the region folk culture for development minority area economy, and protecting, inherit and develop traditional national culture has very important and positive social effect.Exploitation region, the development project with dense traditional national culture breath are one of main visuals field of expert, achievement is striking in many countries and regions, people from Tibet Autonomous Region dredges vast in territory, unimpeded and the shared too late far away each province and city, interior ground of information, brought very big restriction if things go on like this for the development of Tibet Autonomous Region's economy and society, therefore, be necessary, carry out hand-hold electronic equipments Tibetan language information processing research and exploitation in conjunction with actual demand.

Tibetan language is a kind of time-honored minority language, uses more than 1300 year.Books are numerous with document that Tibetan language is write, for record and the magnificent Tibetan culture of succession have been made significant contribution.Tibetan language is still the most basic written the vehicle of communication of the vast Tibetan people masses now.China Tibetan mainly lives in concentrated communities in Tibet autonomous region of Tibetan, Qinghai Province, Gansu Province, Yunnan Province and Sichuan Province.Tibet total population more than 270 ten thousand, wherein Tibetan accounts for more than 96%, and the spread of education rate reaches about 70%, and based on more than 1,000 of the middle and primary schools of Tibetan language and literature, students in middle and primary schools more than 360,000.About Tibetan language, about more than 200 of the middle and primary schools of using more than 1,050,000,90% of Qinghai Province's Tibetan population.Sichuan Province is national second largest Tibetan area.Tibetan 1,250,000,95% uses Tibetan language, and wherein about 40% population is held concurrently and is led to Chinese, and about 60% population is ignorant of Chinese.Based on 226 of the middle and primary schools of Tibetan language and literature, students in middle and primary schools are the people more than 8138.
