Abstract: The present disclosure provides systems and methods for encoding and decoding a machine-readable document. A system can include a computing device comprising a processor and a memory. To encode each entry on a document, the processor can receive an identification of an entry, identify an entry format, and generate an entry fingerprint. The processor can calculate a hash value from the identification, the entry format, and the entry fingerprint, which can then be stored at an address corresponding to the hash value. The processor can generate an optical code, and print the entry and the optical code on the document. To decode the document, the processor can extract the hash value, a first entry identifier, and a user identifier from the optical code. The processor can retrieve a second entry identifier and determine a match with the first entry identifier. The processor can retrieve entry coordinates and extract the entry.

Abstract: The present disclosure provides systems and methods for formatting and generating teaching media for different contexts. A system can receive, from a client computing device, media content having one or more media modalities each having presentation attributes. The system can determine initial formatting rules for the media content based on the presentation attributes of the one or more media modalities. The system can identify a destination format for the media content having a formatting requirement for each of the one or more media modalities of the media content. The system can modify the initial formatting rules for the media content based on the formatting requirement for each of the one or more media modalities. The system can generate an information resource having the destination format based on the modified formatting rules for the media content.

Abstract: The present disclosure provides systems and methods for building an inventory database with automatic labeling. A system can maintain a hierarchical concept tree including labels. Each of the labels is associated with a set of attributes and a respective embedding. The system can receive, from a provider device, a request to generate labels for an item of media content. The request can include a request attribute. The system can generate, using a gated categorical model, document embeddings for the item of media content. The system can select a subset of the labels based on the request attribute. The system can determine a respective label score for each label of the subset of the labels based on the document embeddings and the respective embedding of the label. The system can provide a selected label of the subset of the labels based on the respective label score of the selected label.

Abstract: The present disclosure provides systems and methods for indexing and presenting teaching resources. A system can generate, using a transformer model, a set of embeddings for information resources. The set of embeddings for each of the information resources collectively form an embeddings space comprising a plurality of pivots. The system can store, in a database, identifiers of the information resources in association with the plurality of pivots. The system can generate query embeddings by inputting a set of query terms received from a client device into the transformer model. The system can determine a subset of the information resources based on a distance in the embeddings space between the query embeddings and the plurality of pivots. The system can present, on a display of the client device, the subset of information resources in response to the set of query terms.

Abstract: The present disclosure provides systems and methods for generating deeply integrated presentation gadgets. A system can maintain a plurality of application interfaces each having one or more data fields for presenting content. The system can maintain an information resource having data objects. Each of the data objects can have a content attribute. The system can extract each data object from the information resource based on the respective content attribute. The system can generate a presentation data structure having fields for the information resource based on the extracted data objects. The system can select an application interface for presentation with the information resource. The application interface can populate the one or more data fields of the application interface. The system can present the application interface with the information resource at a client device based on the one or more data fields of the application interface.

Abstract: The present disclosure provides systems and methods for generating dynamic content sets based on real-time feedback. A system can maintain atomic units of content. The atomic units of content can have a topic and a complexity. The system can maintain a client device profile comprising response records for at least one atomic unit of content. The system can receive, from a provider computing device, instructions to generate a dynamic set of content. The instructions can specify a topic distribution and a complexity distribution. The system can generate, based on the instructions, the dynamic set of content as a subset of the plurality of atomic units of content. The system can present an item of the dynamic set of content responsive to receiving a request for the dynamic set of content from the client device.

Abstract: The present disclosure provides systems and methods for extraction of nonverbal communication data from video. A system can include a computing device comprising a processor and a camera.
