Publication number: 20230368068Abstract: The present disclosure relates to systems, methods, and computer-readable media for training and implementing pipeline error detection models to facilitate automated detection of data quality (DQ) issues within recurring data pipelines. For example, systems described herein involve training a pipeline error detection model by first constructing a plurality of DQ constraints for a recurring data pipeline based on ranges of values observed over a history of pipeline executions. The systems may further train the model to predict DQ issues by synthetically applying data variants to historical executions of the recurring data pipeline or to data pipelines having similar characteristics thereto. Once trained, the pipeline error detection model(s) can be applied to new executions of the data pipeline as they become available to quickly and efficiently predict whether a given execution includes a predicted DQ issue therein.Type: ApplicationFiled: May 12, 2022Publication date: November 16, 2023Inventors: Yeye HE, Weiwei CUI, Song GE, Haidong ZHANG, Shi HAN, Dongmei ZHANG, Surajit CHAUDHURI

Publication number: 20230316604Abstract: In accordance with the implementations of the subject matter described herein, there is provided a solution for reusing infographics. In this solution, a group of visual element units is determined from a visual element set comprised in the original infographic. A visual element unit in the group represents an information item in the original infographic. A first correlation between a visual element contained in the visual element unit and the information item and a second correlation between the visual element unit and a further visual element unit in the group are determined. A description for the original infographic is generated based on the first and second correlations. A target infographic is generated by updating the group of visual element units at least based on the description and the target information. In this way, infographics can be converted into reusable templates, thereby simplifying reuse of such infographics and improving user experience.Type: ApplicationFiled: June 30, 2021Publication date: October 5, 2023Inventors: Weiwei CUI, Jinpeng WANG, He Huang, Yun Wang, Haidong Zhang, Chin-Yew LIN, Dongmei ZHANG
