Abstract: Systems and methods are provided for generating queries suitable for evaluating graph comprehension capability. Embodiments of the present disclosure are based on the Sentence Verification Technique (SVT), an empirically validated framework for measuring an individual's comprehension of prose material. Compared to ad hoc methods for testing graph comprehension, embodiments of the present disclosure are less subjective, require less manual effort and subject matter expertise, and address the essential features of a given graph: values and relationships depicted, frames of reference, and style attributes. Embodiments of the present disclosure combat superficial comprehension by testing what the reader has encoded, as opposed to testing the reader's ability at visual recall or ability to look up data without reaching real comprehension.

Abstract: Systems and methods for enhancing exploratory data analysis using a recommender system are provided. The recommender system receives feedback when a set of raw data is analyzed (e.g., from one or more data analysts exploring a data set). Based on the collected feedback, the recommender system can automatically infer the need for certain analytical operations to be performed on a data set. These inferences can be used by the recommender system to infer analytical operations when new data sets are analyzed.
