Abstract: Method and system for training a text-to-content suggestion ML model include accessing a dataset containing unlabeled training data collected from an application, the unlabeled training data being collected under user privacy constraints, applying an ML model to the dataset to generate a pretrained embedding, and applying a supervised ML model to a labeled dataset to train the text-to-content suggestion ML model utilized by the application by utilizing the pretrained embedding generated by the supervised ML model.

Abstract: A method and system for training a text-to-content recommendation ML model includes training a first ML model using a first training data set, utilizing the trained first ML model to infer information about the data contained in the first training data set, collecting the inferred information to generate a second training data set, and utilizing the first training data set and the second training data set to train a second ML model. The second ML model may be a text-to-content recommendation ML model.

Abstract: According to implementations of the subject matter described herein, there is provided a solution for generating a summary of a document. In this solution, feature information of pages comprised in a document is extracted, which characterizes at least one type of content contained in each page. Respective importance of the pages is determined at least based on the extracted feature information. A summary of the document is generated for the document by selecting a predetermined number of pages less than the number of the pages based on the respective importance. Through the solution, instead of providing all the pages, pages containing important content may be determined automatically to serve as the summary of the document. This summary allows the user to learn quickly main content of the document, shorten the time consumed in browsing all documents and/or facilitate location of a document of interest as soon as possible.

Abstract: In embodiments of the present disclosure, there is provided a method of generating a slide for presentation. Upon a target passage for presentation is obtained, a plurality of sentences are generated based on the target passage, and a label associated with each sentence and an icon corresponding to each label are determined. Then, the sentences, labels and icons are displayed in association in a user interface of an application for presentation. According to embodiments of the present disclosure, the illustrated slides can be automatically generated for a passage to be presented, which can improve efficiency of slide making and improve user experience for slide presentation.

Abstract: A metal material having thermodynamic anisotropy has an X-axis hardness of 160-180 HV, an X-axis hardness thermal expansion coefficient of 5×10-6-100×10-6 K?1; a Y-axis hardness of 160-180 HV, a Y-axis hardness thermal expansion coefficient of 5×10-6-100×10-6 K?1; and a Z-axis hardness of 180-250 HV, a Z-axis hardness thermal expansion coefficient of 50×10-6-1000×10-6 K?1. A method for preparing a metal material having thermodynamic anisotropy is also disclosed.

Abstract: A vaginal dilator having side blades or having upper and lower blades including accessorial blades is described. The vaginal dilator includes an upper blade, a pressing member, a lower blade and a handle. The upper and lower blades are connected by a pin. The pressing member is engaged with the handle by a first dilating fixation device. The vaginal dilator having side blades includes an arc-shaped movable locating sleeve rotationally connected with the upper blade. Each end of the sleeve is provided with a mounting base. The mounting base is provided with a joint cavity for receiving a side blade which can be retracted between the upper and lower blades. The back portion of the side blade is provided with a second dilating fixation device engaged with the back end of the upper blade or a locating buckle of the mounting base.

Abstract: A vaginal dilator having side blades or having upper and lower blades comprising accessorial blades includes an upper blade (1), a press handle (3), a lower blade (2) and a handle (4). The upper blade (1) is connected with the lower blade (2) by a pin (5). The press handle (3) is engaged with the handle (4) by a first dilating fixation device. The vaginal dilator having side blades also includes a circular-arc movable locating sleeve (8) rotationally connected with the upper blade (1). Each end of the sleeve (8) is provided with a mounting base (11). The mounting base (11) is provided with a joint cavity for receiving a side blade (12) which can be retracted between the upper and lower blades (1, 2). The back portion of the side blade (12) is provided with a second dilating fixation device engaged with the back end of the upper blade (1) or a locating buckle (15) of the mounting base (11). A channel (18), a channel cover and a slot for inserting the channel cover are provided in the side blade (12).
