Environment sensitive predictive text entry

1. A method, implemented by a mobile device, the method comprising:

receiving, by the mobile device, one or more characters entered by a user of the mobile device;

determining, by the mobile device and based on the one or more characters, a plurality of words that are predicted to be words being entered by the user of the mobile device, the plurality of words being determined using grammar-based predictive techniques;

determining, by the mobile device, a plurality of scores, corresponding to the plurality of words, each of the plurality of scores representing an estimated confidence that the corresponding one of the plurality of words is the word that is being entered by the user;

refining, by the mobile device, the plurality of scores based on environmental data that includes data that describes an environment associated with the user of the mobile device, the refining of the plurality of scores including refining the plurality of scores based on rules that relate parameters of the environmental data to score modifications;

selecting, by the mobile device and based on the refined plurality of scores, a subset of the plurality of words; and

outputting, by the mobile device, the subset of the plurality of words, to a display of the mobile device, as predicted text that is selectable by the user to complete a word or phrase corresponding to the one or more characters entered by the user.

2. The method of claim 1 , where each of the determined plurality of words includes a single word or a phrase.

successively refining the plurality of scores by a plurality of environment modules, where each environment module, of the plurality of environment modules, refines the plurality of scores based on different environmental data.

5. The method of claim 4 , where the plurality of environment modules include at least two of a weather-based module, a location-based module, and a calendar-based module.

6. The method of claim 1 , where the environmental data includes data relating to a current location of the mobile device, the method further comprising:

7. The method of claim 1 , further comprising:

receiving, by the mobile device, the rules from a remotely located server.

8. The method of claim 1 , where the environmental data includes data relating to current weather conditions or a current weather forecast, the method further comprising:

boosting a score of those of the plurality of words that are likely to be used, by the user, in association with the current weather conditions or the current weather forecast.

9. The method of claim 1 , where the environmental data includes data relating to events occurring on a current date, the method further comprising:

boosting a score of those of the plurality of words that are likely to be used, by the user, in association with the events occurring on the current date.

10. A device comprising:

a processor to:

receive one or more characters entered by a user of the device;

determine, based on the one or more characters, a plurality of words that are predicted to be words being entered by the user of the device, the plurality of words being determined using grammar-based predictive techniques;

determine a plurality of scores, corresponding to the plurality of words, each of the plurality of scores representing an estimated confidence that the corresponding one of the plurality of words is the word that is being entered by the user;

refine the plurality of scores based on environmental data that includes data that describes an environment associated with the user of the device, the refining of the plurality of scores including refining the plurality of scores based on rules that relate parameters of the environmental data to score modifications;

select, based on the refined plurality of scores, a subset of the plurality of words; and

output, the subset of the plurality of words, to a display of the device, as predicted text that is selectable by the user to complete a word or phrase corresponding to the one or more characters entered by the user.

11. The device of claim 10 , where each of the determined plurality of words includes a single word or a phrase.

12. The device of claim 10 , where the processor is further to:

refine the plurality of scores based on the environmental data by successively refining the plurality of scores by a plurality of environment modules, where each environment module, of the plurality of environment modules, refines the plurality of scores based on different environmental data.

13. The device of claim 10 , where the environmental data includes data relating to a current location of the mobile device, and where the processor is further to:

boost a score of those of the plurality of words that are likely to be used, by the user, in association with the current location.

14. The device of claim 10 , where the environmental data includes data relating to events occurring on a current date, and where the processor is further to:

boost a score of those of the plurality of words that are likely to be used, by the user, in association with the events occurring on the current date.

15. The device of claim 10 , where the processor is further to:

receive the rules from a remotely located server.

16. The device of claim 10 , where the environmental data includes data relating to current weather conditions or a current weather forecast, and where the processor is further to:

boost a score of those of the plurality of words that are likely to be used, by the user, in association with the current weather conditions or the current weather forecast.

17. A non-transitory computer-readable medium, comprising:

one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:

receive one or more characters entered by a user;

determine, based on the one or more characters, a plurality of words that are predicted to be words being entered by the user, the plurality of words being determined using grammar-based predictive techniques;

determine a plurality of scores, corresponding to the plurality of words, each of the plurality of scores representing an estimated confidence that the corresponding one of the plurality of words is the word that is being entered by the user;

refine the plurality of scores based on environmental data that includes data that describes an environment associated with the user, the refining of the plurality of scores including successively refining the plurality of scores by a plurality of environment modules, where each environment module, of the plurality of environment modules, refines the plurality of scores based on different environmental data;

select, based on the refined plurality of scores, a subset of the plurality of words; and

output, the subset of the plurality of words, as predicted text that is selectable by the user to complete a word or phrase corresponding to the one or more characters entered by the user.

18. The non-transitory computer-readable medium of claim 17 , where the environmental data includes data relating to current weather conditions or a current weather forecast, where the computer-readable medium further comprises:

one or more instructions that, when executed by one or more processors of the device, cause the one or more processors to:
