Abstract: A data processing system implements receiving query text for a search query for textual content recommendation. The query text includes one or more words indicating a type of textual content items being sought. The system implements analyzing the query text using a first machine learning (ML) model to obtain encoded query text, where the first ML model is trained to identify features within the query text and to generate the encoded query text by mapping the features to a hyper-dimensional latent space (HDLS). The system implements identifying one or more content items in a database of encoded content items mapped to the HDLS that satisfy the search query by comparing attributes of the encoded query text with attributes of the encoded content items to identify content items that are closest to the encoded query text within the HDLS, and causing the one or more content items to be displayed.

Abstract: A classroom management system which includes a centralized cloud infrastructure, a first user interface having a geo-locating device in communication with the centralized cloud infrastructure, and a second user communication interface in communication with the centralized cloud infrastructure to define authorized users and authorized locations. The centralized cloud infrastructure transmits an in-attendance signal for each authorized user located in the authorized location based on data received from the geo-locating device to the second user communication interface.
