  1. An Intellectual Chinese Input System for Mobile Phones Based Upon Chinese Phonetic Symbols Author: Chun-Liang Tung, Tung-Shou Chen and Yung-Chang Chiang Source: International Journal of Computer Processing of Oriental Languages, Vol. 15, No. 4 (2002) pp. 395-406 Speaker: Jason Kai-Jung Shih Date:

  2. Outline • Introduction • Chinese input system for mobile phones • Arrayal combinations of phonetic symbols • Experimental results Jason Kai-Jung Shih

  3. Chinese Input System for Mobile Phones • Chinese phonetic symbols • 21 consonants and 16 vowels • 10,000 words and 5,000 common words • Input buttons of mobile phones • 9 or 10 for phonetic symbols • 1 for inputting tones Jason Kai-Jung Shih

  4. General mobile phone. (“方”) ㄈ：1→1→1→1 ㄤ：9→9→9 ㄈㄤ 芳、方、坊、枋、淓、鈁… Intellectual mobile phone. ㄈ：1 ㄤ：6 ㄅㄣ、ㄅㄤ、ㄈㄣ、ㄈㄤ、ㄋㄣ、ㄋㄤ 芳、方、坊、枋、淓、鈁… Chinese Input System for Mobile Phones (cont’) Jason Kai-Jung Shih

  5. Arrayal Combinations of Phonetic Symbols • Example: • 6 Phonetic symbols: • ㄅㄆㄇㄈㄉㄊ • 3 Input buttons: • Combinations: • T=C(5,1)*C(3,1)*C(1,1)=15 • 37 phonetic symbols with 10 buttons • T=C(36,3)*C(32,3)*C(28,3)*C(24,3)*C(20,3)*C(16,3)*C(12,3)*C(8,3)*C(4,4) =139,277,978,876,149,282 Jason Kai-Jung Shih

  6. Phonetic Symbol Combinations Jason Kai-Jung Shih

  7. Reduce the Combinations (Cont’) • 8 phonetic symbols with 2 buttons (“方”) • Original: “1ㄅㄆㄇㄈ” and “2ㄢㄣㄤㄥ” • ㄅㄢ、ㄅㄣ、ㄅㄤ、ㄅㄥ、ㄆㄢ、ㄆㄣ、ㄆㄤ、ㄆㄥ、ㄇㄢ、ㄇㄣ、ㄇㄤ、ㄇㄥ、ㄈㄢ、ㄈㄣ、ㄈㄤ、ㄈㄥ。 • Arranged: “1ㄅㄈㄢㄣ” and “2ㄆㄇㄤㄥ” • ㄅㄤ、ㄅㄥ、ㄈㄤ、ㄈㄥ。 Jason Kai-Jung Shih

  8. Reduce the Combinations (Cont’) • 37 phonetic symbols with 9 buttons • Sequential order • T=C(36,3)*C(32,3)*C(28,3)*C(24,3)*C(20,3)*C(16,3)*C(12,3)*C(8,3)*C(4,4) =139,277,978,876,149,282 • Arranged order • Choose 18 of 21 consonants • T=C(17,1)*C(15,1)*C(13,1)*C(11,1)*C(9,1)*C(7,1)*C(5,1)*C(3,1)*C(1,1) =33,459,425 Jason Kai-Jung Shih
