  • Patent number: 11151895
    Abstract: Accordingly, embodiments of the present invention advantageously account for item discrimination in a single-parameter logistic model used for measuring a test-taker's ability and an item's difficulty. Accounting for item discrimination improves the reliability of a test without increasing the number of test items. To account for item discrimination in a single-parameter logistic model, this invention uses the correlation between item response (correct or incorrect) and total test score or other measure of test-taker ability to obtain a Bayesian estimate of the correct-response probability (between zero and one). This correlation is a measure of item discrimination. The numerator in the formula for this correlation contains the difference between the average test score of test-takers who got the item right and the average test score of test-takers who got the item wrong.

  • Patent number: 11049409
    Abstract: Systems and methods are provided for automatically scoring a response and statistically revaluating whether it can be considered as aberrant. In one embodiment, a constructed response is evaluated via a pre-screening stage and a post-hoc screening stage. The pre-screening stage attempts to determine whether the constructed response is aberrant based on a variety of aberration metrics and criteria. If the constructed response is deemed not to be aberrant, then the post-hoc screening stage attempts to predict a discrepancy between what score an automated scoring system would assigned and what score a human rater would assign to the response. If the discrepancy is sufficiently low, then the constructed response may be scored by an automated scoring engine. On the other hand, if the constructed response failed to pass either of the two stages, then a flag may be raised to indicate that additional human review may be needed.

  • Patent number: 10878197
    Abstract: A machine-learning component of a conversational user-interface system retrieves records of human question-and-answer sessions from heterogenous sources. A sequence of image-processing operations converts each source into a set of grayscale images. Each image is segmented into disjoint sections as a function of the textures, edges, and contours that make up the image's content. Each section is tagged with a vector of parametric values that identify characteristics of the section's content from which may be inferred semantic meaning. A cognitive function intelligently analyzes the vectors to classify each section as containing a question, an answer to a question, non-textual media, or other types of content. Another cognitive function merges and organizes the sections into question-answer pairs and the vectors associated with each pair are stored in a corpus that is submitted to the self-learning user interface during a machine-learning training session.

The topological structure of each form includes vertical and horizontal ordered sequences of text phrases in the form, which describe directional relationships among text phrases but not their distances. A partial structure alignment method is used in the comparison, where insertions of text in the topological structure of the filled form relative to that of the empty form is not penalized, but deletions and substitutions are penalized. Based on this comparison, some text phrases in the filled form are matched to the those in the empty form, and unmatched text in the filled form is deemed user-filled data. The method further associates user-filled data with fields of the form based on a settings file of the empty form.

  • Patent number: 10446044
    Abstract: A computer-implemented method of calibrating an assessment model for assessing responses includes accessing a plurality of training responses with a processing system for training an assessment model. The processing system analyzes the plurality of training responses to derive values of multiple features of the training responses. The processing system trains the assessment model based on the values of the multiple features of the training responses and a portfolio score for each individual associated with the plurality of training responses utilized in the training. The portfolio score for each individual corresponds to a measure of proficiency based on multiple writing samples constructed by the individual. The processing system determines, based on said training, a weight for each of the multiple features. The processing system calibrates the assessment model to include the weights for at least some of the features such that the assessment model is configured to generate scores for responses.

  • Patent number: 10373512
    Abstract: Mechanisms for automatically grading a large number of solutions provided by learners in response to an open response mathematical question. Each solution is mapped to a corresponding feature vector based on the mathematical expressions occurring in the solution. The feature vectors are clustered using a conventional clustering method, or alternatively, using a presently-disclosed Bayesian nonparametric clustering method. A representative solution is selected from each solution cluster. An instructor supplies a grade for each of the representative solutions. Grades for the remaining solutions are automatically generated based on their cluster membership and the instructor supplied grades. The Bayesian method may also automatically identify the location of an error in a given solution. The error location may be supplied to the learner as feedback. The error location may also be used to extract information from correct solutions. The extracted information may be supplied to a learner as a solution hint.

  • Patent number: 9767707
    Abstract: An optimization engine builds a set of test forms, called a pallet for use in a qualification test setting. The pallet is generated using a optimization engine programmed with constraints and goals for each test form in the pallet and for the pallet in general. A test information floor is set at the cut point of the test which causes test items to be focused at the area of the test where the pass/fail decision is made. The test items may be separated into families by assigning test items selected for a test form in each test generation cycle to one of several families. Because each family has unique test items compared to other families, a person re-taking a qualification test from a particular pallet may be given a test form from another family, ensuring that no item from the first administration will appear on the subsequent test.
