T9 Predictive Text Algorithm C++ Implementation

Description

T9, which stands for Text on 9 keys, is a USA-patented predictive text technology for mobile phones (specifically those that contain a 3x4 numeric keypad), originally developed by Tegic Communications, now part of Nuance Communications.

T9 was used on phones from Verizon Wireless, NEC, Nokia, Samsung Electronics, Siemens, Sony Ericsson, Sanyo, Sagem and others. It was also used by Texas Instruments PDA Avigo during the late 1990s. Its main competitors are iTap created by Motorola, SureType created by RIM, Eatoni's LetterWise and WordWise, and Intelab's Tauto.

Algorithm

In order to achieve compression ratios of close to 1 byte per word, T9 uses an optimized algorithm which maintains the order of words, and partial words (also known as stems) but because of this compression, it over-generates words which are sometimes visible to the user as "junk words". This is a side effect of the requirements for small database sizes on the lower end embedded devices.
