Abstract: Three-dimensional positional spatial olfaction for virtual marketing associates a product with a product location within a virtual reality environment and identifies a product aroma associated with the product. A distance and a direction from the product location to a positional presence of a participant within the virtual reality environment is determined, and the product aroma is delivered to the participant in accordance with the distance and the direction. Delivery of the product aroma to the participant in accordance with the distance and the direction is used to lead the participant through the virtual reality environment to the product location where an interface for obtaining a physical copy of the product is displayed to the participant.

Abstract: Systems, methods, and computer-readable media are described for determining a score for a target student answer using unlabeled data. The target answer is provided by a student to a question for which there is no ground-truth answer data. A set of student answers serves as a set of pseudo-reference answers and a classifier is used to score each answer based on each other answer. In this manner, each student answer serves as a pseudo-reference answer for each other student answer. A clustering approach can also be employed to cluster a set of student answers into clusters. The centroids of the clusters can then serve as the set of pseudo-reference answers. Clustering improves the robustness and efficiency of the score determined for a target student answer.

Abstract: Context appropriate errors are injected into conversational text generated by conversational agents. The conversational agent creates an imperfect conversational text containing at least one text entry error added to the original conversational text. A confidence level that at least one of context and meaning of the imperfect conversational text is consistent with the context and meaning of the original conversational text is determined, and the imperfect conversational text is communicated to a human recipient if the confidence level is above a pre-defined threshold.
