Abstract: A method provides an automatic notification manner of data changes. After collecting information related to a target user such as a dataset, a data dashboard, or a data report, the analysis preference of the user can be determined based on the collected information. Then, upon the dataset is updated, a variety of critical data changes in the dataset may be detected as an alert, and a notification related to the alert may be provided to the user via various manners. The method does not require the user to manually configure or create an alert rule for data changes, which makes data-driven alerting much easier for the user, thereby improving the user experience.

Abstract: According to implementations of the subject matter described herein, there is provided a solution for data embedding and data extraction in images. To perform data embedding, a target region for data embedding is determined from a source image, such as a chart image. Target data to be embedded is converted into a sequence of logical values represented in a predetermined format. Based on the sequence of logical values, image values of one or more image elements in the target region are changed such that the changed image values in the target region can be used to convey the sequence of logical values corresponding to the target data. The variations in image values are within a predetermined range such that no significant data distortion of perception distortion is caused by the data embedding. In a subsequent process, the embedded data can also be easily extracted from the image for use.

Abstract: According to implementations of the present disclosure, there is provided a solution for training an object linking model. A target semantic object and a first text sequence comprising text elements in a natural language are obtained. A first confidence score of the target semantic object being mentioned in the first text sequence is determined. A second confidence score of the target semantic object being mentioned in the first text sequence is determined with a first text element being ignored from the first text sequence. An object linking model is trained at least based on a first confidence difference between the first and second confidence scores, the first text sequence and the target semantic object. In this way, the cost and difficulty in labeling a training dataset may be reduced and the labeling accuracy and efficiency may be improved.

Abstract: A method provides an automatic notification manner of data changes. After collecting information related to a target user (202) such as a dataset, a data dashboard, or a data report, the analysis preference of the user can be determined based on the collected information (204). Then, upon the dataset is updated, a variety of critical data changes in the dataset may be detected as an alert (206), and a notification related to the alert may be provided to the user via various manners (208). The method does not require the user to manually configure or create an alert rule for data changes, which makes data-driven alerting much easier for the user, thereby improving the user experience.
