Patent Images
1. A computer-implemented method for generating vocabulary questions, the method comprising:
- obtaining, by a computer processor, a sentence from a database;
determining, by the computer processor, whether a word of the obtained sentence, the word having multiple definitions, is used in the sentence consistently with one of the multiple definitions which has been selected as a target definition;
responsive to a result of the determining being that the use of the word in the sentence is consistent with the one of the multiple definitions, providing, by the computer processor, the sentence for use to generate a question concerning the word of the sentence; and
outputting, by the computer processor, the question.

Abstract
An adaptive learning system and method provides for automatically generating question types to a user for word comprehension and selecting multiple choice answers for display. Questions are developed for the user by obtaining online content and indexing the content into individual sentences and questions. The system provides questions in a series of rounds to the user and then adaptively tracks the progress of the user based on the categorization of each question.

21. A computer-implemented method for generating vocabulary questions in an adaptive learning system, the method comprising:
-
outputting, by a computer processor, questions in a series of rounds to a user, wherein each of the rounds contains a determined number of question slots; allocating a set of the question slots for questions previously missed by the user; distributing remaining question slots to additional questions concerning words about which the user previously correctly answered questions; subsequently determining whether any additional question slots are available; and if the determination is that there is one or more additional question slots available, allotting the available question slots to new questions containing words about which the user has not been tested. - View Dependent Claims (22, 23, 24, 25, 26)

27. An adaptive learning system for generating questions and multiple choice answers to assist in teaching word comprehension, the system comprising:
a computer processor configured to; obtain a sentence; determine whether a word of the obtained sentence, the word having multiple definitions, is used in the sentence consistently with one of the multiple definitions which has been selected as a target definition; responsive to a result of the determination being that the use of the word in the sentence is consistent with the one of the multiple definitions, provide the sentence for use to generate a question concerning the word of the sentence; and output the question and a set of selectable multiple choice answers. - View Dependent Claims (28, 31, 32)

33. A hardware computer-readable medium having stored thereon instructions executable by a processor, the instructions which, when executed by the processor, cause the processor to perform a method for generating vocabulary questions, the method comprising:
-
obtaining a sentence from a database; determining whether a word of the obtained sentence, the word having multiple definitions, is used in the sentence consistently with one of the multiple definitions which has been selected as a target definition; responsive to a result of the determining being that the use of the word in the sentence is consistent with the one of the multiple definitions, providing the sentence for use to generate a question concerning the word of the sentence; and outputting the question.

34. A computer-implemented method for generating vocabulary questions, the method comprising:
-
obtaining, by a computer processor, a sentence from a database, the sentence having been assigned to one of a plurality of quality categories; using the sentence, by the computer processor, to generate a question concerning a word of the sentence, the question being one of a plurality of question types selected based on the quality category to which the sentence has been assigned; and outputting, by the computer processor, the question; wherein the quality category; corresponds to at least one ratio, each of the at least one ratio being of text, in the sentence, which is of a respective predetermined characteristic, relative to text, in the sentence, which is not of the respective predetermined characteristic, the predetermined characteristic being that the text at least one of includes a non-alphanumeric character and is an acronym; and is assigned such that the larger the at least one ratio of the text of the predetermined characteristic relative to the text that is not of the predetermined characteristic, the lower the quality category.

35. A computer-implemented method for generating vocabulary questions, the method comprising:
-
obtaining, by a computer processor, a sentence from a database, the sentence having been assigned to one of a plurality of quality categories; using the sentence, by the computer processor, to generate a question concerning a word of the sentence, the question being one of a plurality of question types selected based on the quality category to which the sentence has been assigned; and outputting, by the computer processor, the question; wherein the quality category corresponds to both; (a) a determined degree to which the sentence has correctly applied the word; and (b) at least one of (i) at least one ratio, each of the at least one ratio being of text, in the sentence, which is of a respective predetermined characteristic, relative to text, in the sentence, which is not of the respective predetermined characteristic, the predetermined characteristic being that the text at least one of includes a non-alphanumeric character and is an acronym; and
(ii) a sentence length.
