Abstract

The present invention provides a method and device for realizing Chinese character input based on uncertainty information, wherein the method comprises: receiving input information from a user; extracting at least two types of uncertainty information of Chinese characters to be input, from the input information; and, determining the matched Chinese characters according to the at least two types of uncertainty information and outputting the matched Chinese character(s). The device comprises a receiving module, an extracting module and a matching module. The method and device as provided by the present invention allow a user who has incomplete memory of pronunciation or glyph information of Chinese characters to be input to realize correct input of the Chinese characters by defining a certain range for candidate characters corresponding to the Chinese characters to be input, in combination with at least two types of the extracted uncertainty information of the Chinese characters to be input.

First claim

What is claimed is:

1. A method for providing Chinese character based on handwriting input, comprising:
receiving a text string including one or more Chinese characters, one or more phonetic alphabets and one or more blanks from a handwriting input interface, wherein the one or more phonetic alphabets and/or the one or more blanks correspond to one or more uncertain Chinese characters;
recognizing information on the one or more Chinese characters;
extracting at least two types of uncertainty information on the uncertain Chinese characters based on the information on the one or more Chinese characters, wherein each of the at least two types of uncertainty information has a predetermined priority respectively;
determining certain Chinese characters each of which corresponds to each of the uncertain Chinese characters according to at least two types of language models based on the at least two types of uncertainty information by matching the certain Chinese characters in a sequence according to the predetermined priority, wherein each of the language models is scored by scoring a Chinese character language model or scoring a phonetic alphabet language model; and
outputting the certain Chinese characters.

2. The method for claim 1 , wherein the at least two types of uncertainty information includes at least two of phonetic alphabet (Pinyin) information, tone information, structural configuration information, radical information, homophone information, and location information.

3. The method for claim 2 , wherein the tone information is extracted by:
extracting tone symbols corresponding to the tone information, the tone symbols including , ´, {hacek over ( )} or {grave over ( )}; or
extracting a certain number or letter indicative of the tone information.

4. The method for claim 2 , wherein the location information is extracted by extracting a blank or a certain character.

5. The method for any one of claims 2 - 4 , wherein the recognizing information on the one or more Chinese characters comprises:
detecting a user operation within an input area; and
recording at least two types of uncertainty information input by the user operation.

6. The method for claim 5 , further comprising:
displaying the at least two types of uncertainty information on a screen.

7. The method for claim 2 , wherein the determining the certain Chinese characters comprises:
analyzing matching results for each of the at least two types of language models to determine the certain Chinese characters with a highest matching degree; and
wherein outputting the certain Chinese characters comprises outputting the certain Chinese characters with the highest matching degree.

8. The method for claim 7 , further comprising:
determining a priority for the at least two types of uncertainty information; and
matching the certain Chinese characters in a sequence according to the priority with the at least two types of corresponding models.

9. A device for providing Chinese character based on handwriting input, comprising a processor to implement:
a communicator configured to receive a text string including one or more Chinese characters, one or more phonetic alphabets, and one or more blanks from a handwriting input interface, wherein the one or more phonetic alphabets and/or the one or more blanks correspond to one or more uncertain Chinese characters; and
a controller configured to:
recognize information on the one or more Chinese characters;
extract at least two types of uncertainty information on the uncertain Chinese characters based on the information on the one or more Chinese characters, wherein each of the at least two types of uncertainty information has a predetermined priority respectively,
determine certain Chinese characters each of which corresponds to each of the uncertain Chinese characters according to at least two types of language models based on the at least two types of uncertainty information by matching the certain Chinese characters in a sequence according to the predetermined priority, wherein each of the language models is scored by scoring a Chinese character language model and a phonetic alphabet language model, and
output the certain Chinese characters.

10. The device for claim 9 , wherein the at least two types of uncertainty information extracted by the controller includes at least two of phonetic alphabet (Pinyin) information, tone information, structural configuration information, radical information, homophone information, and location information.

11. The device for claim 10 , wherein the controller is further configured to extract the tone information by:
extracting tone symbols corresponding to the tone information, the tone symbols including, , ´, {hacek over ( )} or {grave over ( )}; or
extracting a certain number or letter indicative of the tone information.

12. The device for claim 10 , wherein the controller is further configured to extract the location information by extracting a blank or a certain character.

13. The device for any one of claims 10 - 12 , wherein the controller is further configured to recognize the one or more Chinese characters by:
detecting a user operation within an input area; and
recording the at least two types of uncertainty information input by the user operation.

14. The device for claim 13 , wherein the controller is further configured to display the at least two types of uncertainty information on a screen.

15. The device for claim 14 , wherein the controller is further configured to display updated uncertainty information on the screen when detecting a modification of the at least two types of uncertainty information by a user within an input area.

16. The device for claim 10 , wherein the controller is further configured to:
analyze matching results for each of the at least two types of language models to determine the certain Chinese characters with a highest matching degree, and
wherein the certain Chinese characters output by the controller are the certain Chinese characters with the highest matching degree.

17. The device for claim 16 , wherein the controller is further configured to:
determine a priority for the at least two types of uncertainty information; and
match the certain Chinese characters in a sequence according to the priority with the at least two types of corresponding models.

18. The device for claim 15 , wherein the controller is further configured to:
receive input information setting a priority for the at least two types of uncertainty information.
