TAILIEUCHUNG - Báo cáo khoa học: "The Wild Thing!"

Suppose you are on a mobile device with no keyboard (., a cell or PDA). How can you enter text quickly? T9? Graffiti? This demo will show how language modeling can be used to speed up data entry, both in the mobile context, as well as the desktop. The Wild Thing encourages users to use wildcards (*). A language model finds the k-best expansions. Users quickly figure out when they can get away with wildcards. General purpose trigram language models are effective for the general case (unrestricted text), but there are important special cases like searching over popular web. | The Wild Thing Kenneth Church Bo Thiesson Microsoft Research Redmond WA 98052 USA church thiesson @ Abstract Suppose you are on a mobile device with no keyboard . a cell or PDA . How can you enter text quickly T9 Graffiti This demo will show how language modeling can be used to speed up data entry both in the mobile context as well as the desktop. The Wild Thing encourages users to use wildcards . A language model finds the k-best expansions. Users quickly figure out when they can get away with wildcards. General purpose trigram language models are effective for the general case unrestricted text but there are important special cases like searching over popular web queries where more restricted language models are even more effective. 1 Motivation Phone App Cell phones and PDAs are everywhere.

It is bizarre that people are typing on their phones given how painful it is. Talking on the phone is a collocation but typing on the phone is not. Slate id 2111773 recently ran a story titled A Phone You Can Actually Type On with the lead If you ve tried to zap someone a text message recently you ve probably discovered the huge drawback of typing on your cell phone. Unless you re one of those cyborg Scandinavian teenagers who was born with a Nokia in his hand pecking out even a simple message is a thumb-twisting chore. There are great hopes that speech recognition will someday make it unnecessary to type on your phone for SMS or any other app but speech recognition won t help with the rudeness issue. If people are typing because they can t talk then speech recognition is not an option. Fortunately the speech community has developed .
