Abstract


With the computer technology and network technology, the rapid development of Tibetan information processing has made great progress. However, due to Tibetan national standards with international standards coding and coding introduced lagging behind, currently on the market a variety of software vendors to take their own coding standards , making all kinds of Tibetan data between sites are not compatible , the information can not be shared , thus seriously affecting the development of Tibetan information processing . Most literature is still using the whole word encoding GB2312 coding system as Tibetan coded . This paper first discusses the Tibetan coded identification and conversion of the key issues , describes the structural characteristics and statistics Tibetan characteristics , describes the various possible identification criteria and were analyzed and compared . Used to determine the distance between nodes Tibetan sound is characterized by regularity and frequency syllable recognition method is characterized Founder Windows, Founder Dos, with the yuan, Huaguang Windows, Huaguang Dos, Pandita , ISO / IEC 10646 basic set , national Institute of Standards extension A Tibetan coded identification ; and be able to correctly distinguish Tibetan text with other languages ??. Second, in order to achieve a variety of non-standard encoded Tibetan language Tibetan national or international standards, a unified coding conversion , this paper carried out the work into two parts: First, to develop systems based on non-standard GB2312 Tibetan coded set of extensions to the national standards coding between the query table, while according to the analysis of the characteristics need to convert the encoding characteristics coded based query algorithm to achieve the Founder Windows, Founder Dos, with the yuan, Huaguang Windows, Dos , etc. Huaguang Tibetan coded to ISO / IEC 10646 basic set and national standards extension A Tibetan encoding conversion ; but also to achieve the national standard extension A to ISO / IEC 10646 basic set conversion. Final design of the Tibetan coded identification and conversion system, through large data sets of the system were tested. By the test results shows that the system for the identification and conversion Tibetan coded to achieve the desired results .
