Abstract: A data dictionary generation system automatically populates and updates a data dictionary for listings offering shared data. A data dictionary includes metadata describing the shared data, including the individual objects, such as the individual tables, schemas, views, and functions. The shared data and each individual data object may be described in the data dictionary by a set of data fields that corresponds to the shared dataset or the object type of the individual object. The data dictionary can be presented to data consumers along with the description of the listing to provide data consumers with a comprehensive description of the shared data provided by a listing, including a high-level summary of the shared data and description of each individual object included in the shared data. The data dictionary allows data consumers to understand the contents of the shared data and how to use the shared data.

Abstract: Provided are an interaction method and apparatus in a live streaming room, a device, and a storage medium. The method comprises: in response to a trigger operation for a preset drawing entry on a live streaming room page, jumping to a graphic drawing page from the live streaming room page, a drawing trajectory set for a preset object being displayed on the graphical drawing page; when a drawing stroke on the graphic drawing page is received, matching the drawing stroke with the drawing trajectory; and if it is determined that the drawing stroke is successfully matched with the drawing trajectory, displaying prompt information about successful participation in a preset activity, the preset activity and the preset drawing entry having a correspondence.

Abstract: Introduced here are approaches for identifying the optimal send time for messages by accounting for hidden confounders, such as the content of those messages, delivery channel, etc. These approaches use a causal inference framework to discover and then remove the impact of hidden confounders. These approaches may be employed by a marketing and analytics platform (or simply “marketing platform”) that may be used to design, implement, or review digital marketing campaigns. The marketing platform can consider the send time as a treatment and then employ machine learning (ML) models that consider the send time, features of the recipient, and hidden confounders to produce a ranked series of send times with the effect of the hidden confounders marginalized. Approaches to performing offline evaluations that mimic A/B tests using data related to existing field experiments are also introduced here.

Abstract: A method and system for dynamically customizing website displays is provided. Upon receiving a request from a user to display a web page, the geographic locations of items described on the web page is determined as well as the geographic location of the user. A relevance of the locations on the web page to the user is determined according to proximity. If the locations are determined to be relevant to the user weather data associated with the locations on the web page and the location of the user is retrieved. Content on the web page related to the weather data is identified, and the standard style sheet for the web page is modified to generate a customized style sheet, wherein weather-related content is displayed more prominently than it would be in the standard style sheet.

Abstract: The present disclosure relates to systems, methods, and non-transitory computer readable media for determining send times for distributing digital content to client devices utilizing a recommendation system approach. For example, the disclosed systems can utilize a recommendation system model such as a matrix factorization model, a factorization machine model, and/or a neural network to implement collaborative filtering to generate predicted response rates for particular candidate send times. Based on the predicted response rates indicating likelihoods of receiving responses for particular send times, the disclosed system can generate a distribution schedule to provide electronic communications at one or more of the send times.

Abstract: An expandable hydrogel structure formed of a housing with a superabsorbent material disposed and sealed therein, particularly wherein the housing is fabricated of a hydrogel membrane with a plurality of macropores providing fluid communication between the superabsorbent material and an exterior of the housing. Exposure of the superabsorbent material to an expansion trigger expands the housing from an initial size to an expanded size that is at least about 50 times to at least about 100 times the initial size. One or more therapeutic agents can further be disposed within the housing to provide controlled release of the therapeutic agents from the expanded housing for extended periods.
