Naxi dongba pictograph input method based on graphic topological feature recognition

Abstract

The invention relates to a Naxi dongba pictograph input method based on graphic topological feature recognition, and the method comprises the steps of: extracting 5 types of topological feature values by taking a dongba classic as a blueprint, and storing into a data table as feature codes, and using Unicode code of dongba pictograph as recognition codes; sequentially inputting needed topological features of Naxi pictograph according to the 5 feature codes, inputting all 5 topological features, or selectively partially inputting easily-identified topological features, and replacing difficultly-identified topological features with *; searching in the data table by using an input method according to the input topological features; after a user selects dongba characters to be input, searching for the Unicode code corresponding to the dongba character in the data table; extracting corresponding Naxi pictograph profile data in a character library and displaying according to the Unicode code, so input of a complete Naxi dongba pictograph is finished. The input method needs no memory, is less in repeated code, fast to learn and efficient, and can be widely applied in the field of character input.

Description

technical field [0001] The invention relates to a character input method, in particular to a Naxi Dongba pictograph input method which is recognized based on graphic topological features. Background technique [0002] Dongba script is a picture pictograph with both ideographic and phonetic elements. Its character form is very primitive, even more primitive than that of oracle bone inscriptions. It belongs to the early form of the origin of characters and is one of the few pictographs still alive in the world. Known as the "living fossil" of writing, it is considered by the international academic community to be the only hieroglyph still in use in the world today. In 2003, the Naxi Dongba classics were listed as "World Memory Heritage" by UNESCO. In 2012, the National Social Science Fund Major Project - "World Memory Heritage" Dongba Classics Inheritance System Digital International Sharing Platform Construction Research (Project No. : 12&ZD234) began to implement, a large n...

Problems solved by technology

However, the pinyin input method has a high code repetition rate and slow word input speed on the one hand, and on the other hand requires users to be very familiar with the pronunciation of Naxi. It can be applied to very few Dongba experts, but it is too difficult for the wider public

2. Compared with the pinyin input method, the font code input method has a lower code repetition rate. For example, the method of Naxi pictograph input based on a specific block as a coding unit invented by Dalian University for Nationalities also has the disadvantage that the user needs to understand Dongba The characters are very familiar, and the ability to quickly decompose Dongba characters into designated blocks is required, and the keyboard positions corresponding to different coding units need to be memorized, which takes a long time to master

3. Compared with the above two methods, the classification spelling input method has a lower code repetition rate, but the fields involved in Dongba classics include philosophy, history, religion, medicine, astronomy, geography, folk customs, animals and plants, military affairs, and literature. According to Fang Guoyu's dictionary, its characters can be divided into astronomical phenomena, geography, plants, birds, beasts, insects and fish, personal names, personnel affairs, shapes, clothing, food, living, utensils, behaviors, shapes, numbers, religions, and legends. There are 18 categories such as ancient names and titles, with many classifications and complex classification codes. In addition to this, the input method invented by Dali University also needs to memorize the spelling codes. Like the above two methods, it is complicated for ordinary users to use. , master time-consuming
