Abstract: Systems and methods are validating data in a data set. A data set including data to validate and a validator to use in validating the data is selected based on user input generated based on interactions of a user with a graphical user interface. The validator is applied to the data to determine whether one or more statistics generated through application of the validator to the data is valid or invalid based on a validation routine associated with the validator. A data quality report indicating whether the data set is valid or invalid, based on a determination of whether the one or more statistics is valid or invalid, is generated and selectively presented to the user through the graphical user interface.

Abstract: A data analysis system presents a user interface to allow a user to provide a natural language query pertaining to a dataset, wherein the dataset is associated with a data object model comprising a plurality of objects and receives, via the user interface, user input specifying the natural language query. The data analysis system further modifies, in the user interface, the user input to visually indicate one or more portions of the natural language query that each represent one of the plurality of objects and presents, in the user interface, a response to the natural language query, the response being based on data from the dataset, the data corresponding to the one of the plurality of objects.

Abstract: A data analysis system receives a data string comprising a natural language query pertaining to a dataset, wherein the dataset is associated with a data object model comprising a plurality of objects, and parses the data string to identify a plurality of individual words within the data string. The data analysis system identifies, based on the plurality of individual words, one or more objects of the plurality of objects, wherein the one or more objects are associated with the natural language query in the data string. The data analysis system further determines one or more artifacts that are based on the dataset, wherein each of the one or more artifacts is associated with one of the one or more objects and provides a response to the natural language query.
