  • Systems for determining representations of entities based on graph data using a language model
    Patent number: 12681990
    Abstract: A large language model (LLM) may be used to generate an overall entity representation of an entity using an input that includes individual representations based on graph data, text data, and image data associated with the entity. Graph data that represents characteristics of the entity and types of relationships between the entity and other entities is used to generate a graph representation. Text associated with the entity is used to generate a text representation. Image data associated with the entity is used to generate an image representation. These representations are used to generate an input to the LLM, which is trained to generate an entity representation based on the input. The entity representation may be used by other models, such as to determine entities having similar or differing characteristics.
