Information processing apparatus, image processing apparatus, and non-transitory computer readable medium storing program

1. An information processing apparatus comprising

a processor configured to

extract, from a document, words of a plurality of categories,

select one extracted word from each of the plurality of categories,

generate a first character string by arranging the selected words in accordance with a rule, wherein the rule determines positions of the selected words within the first character string based on the categories of the selected words,

in response to reception of an operation being performed on a first word among the selected words in the first character string from a user, present to the user one or more candidate words that belong to a category of the first word in the first character string,

in response to reception of another operation being performed on a user-selected word selected from among the one or more candidate words, generate a second character string by replacing the first word in the first character string with the user-selected word, and

store the second character string in a memory in association with the document.

2. The information processing apparatus according to claim 1 , wherein the processor is configured to

when presenting a plurality of candidate words as the one or more candidate words, present the plurality of candidate words in an order in accordance with a predetermined criterion.

3. The information processing apparatus according to claim 2 , wherein the order is determined by frequencies of previous selections of each of the plurality of candidate words by the user.

4. The information processing apparatus according to claim 3 , wherein the order is determined by locations of the plurality of candidate words within the document.

5. The information processing apparatus according to claim 4 , wherein the locations are relative locations to a predetermined word in the document.

6. The information processing apparatus according to claim 2 , wherein the order is determined by locations of the plurality of candidate words within the document.

7. The information processing apparatus according to claim 6 , wherein the locations are relative locations to a predetermined word in the document.

8. The information processing apparatus according to claim 6 , wherein the locations are relative locations to a graphical object in the document.

9. The information processing apparatus according to claim 2 , wherein the order is based on dominance of each of the plurality of candidate words in the document.

10. The information processing apparatus according to claim 9 , wherein the order is based on proportional frequencies of occurrences of the plurality of candidate words in the document to all words in the document.

11. The information processing apparatus according to claim 1 , wherein the processor is configured to

in response to reception of an operation by the user to move the first word in the first character string to another position:

move the first word to the another position within the first string, and

update the rule to define that a word belonging to the category of the first word be positioned at a position corresponding to the another position.

12. The information processing apparatus according to claim 11 , wherein the processor is configured to

in response to the reception of an operation by the user to move the first word in the first character string to another position and reception of an instruction from the user to reflect a movement of the first word to the rule, update the rule to define that a word belonging to the category of the first word be positioned at a position corresponding to the another position.

13. The information processing apparatus according to claim 1 , wherein the rule is user-specific.

14. The information processing apparatus according to claim 1 , wherein the processor is configured to

in response to any word in the first character string satisfying a predetermined condition, present the word satisfying the predetermined condition in a second format that is different from a first format in which a rest of the first character string is presented.

15. The information processing apparatus according to claim 14 , wherein the predetermined condition is the number of other words belonging to the category of the word in the first string being equal to or larger than a threshold.

16. The information processing apparatus according to claim 14 , wherein the predetermined condition is a difference between a rating of the word in the first character string and a second rating of another word belonging to the category of the word being smaller than a threshold, wherein the first rating and the second rating is based on a predetermined criterion.

17. The information processing apparatus according to claim 1 , wherein the processor is configured to

in response to a category of any word in the first character string satisfying a predetermined condition, present the first character string together with information related to the word satisfying the predetermined condition.

18. The information processing apparatus according to claim 1 , wherein the processor is further configured to

in response to reception of an operation being performed on a second word among the selected words in the first character string from the user, present to the user one or more other candidate words that belong to another category of the second word in the first character string, wherein the second word is different from the first word.

19. An image processing apparatus comprising:

a scanner; and

a processor configured to

acquire an image of a document read by the scanner,

extract, from the document shown in the image, words of a plurality of categories,

select one extracted word from each of the plurality of categories,

generate a first character string by arranging the selected words in accordance with a rule, wherein the rule determines positions of the selected words within the first character string based on the categories of the selected words,

in response to reception of an operation being performed on a first word among the selected words in the first character string from a user, present to the user one or more candidate words that belong to a category of the first word in the first character string,

in response to reception of another operation being performed on a user-selected word selected from among the one or more candidate words, generate a second character string by replacing the first word in the first character string with the user-selected word, and

store the second character string in a memory in association with the document.

20. A non-transitory computer readable medium storing a program causing a computer having a processor to execute a process comprising:

extracting, from a document, words of a plurality of categories;

selecting one extracted word from each of the plurality of categories;

generating a first character string by arranging the selected words in accordance with a rule, wherein the rule determines positions of the selected words within the first character string based on the categories of the selected words;

in response to reception of an operation being performed on a first word among the selected words in the first character string from a user, presenting to the user one or more candidate words that belong to a category of the first word in the first character string;

in response to reception of another operation being performed on a user-selected word selected from among the one or more candidate words, generating a second character string by replacing the first word in the first character string with the user-selected word; and

storing the second character string in a memory in association with the document.
