Handheld electronic device and method for disambiguation of compound text input and that employs N-gram data to limit generation of low-probability compound language solutions

An electronic device comprising:

• a processor apparatus comprising a processor and a memory having stored therein a number of language objects and a number of associated frequency objects, at least some of the language objects each comprising a number of characters;
• a display;
• and
• the memory further having stored therein one or more routines which, when executed on the processor, cause the electronic device to perform operations comprising:
• detecting an ambiguous text input including a set of characters;
• generating a number of compound language solutions by identifying a language object that corresponds with an initial set of characters of the ambiguous text input and identifying another language object that corresponds with another portion of the ambiguous text input;
• for at least a first compound language solution, generating a junction object comprising a terminal character of the language object and an initial character of the another language object;
• determining for at least the first compound language solution a frequency value of a language object corresponding with the junction object or a frequency value of zero if no language object corresponding with the junction object is found;
• and
• employing the frequency value in outputting with the display a representation of each of at least some of the compound language solutions.
