Abstract
Systems or techniques that facilitate coherent hyperedges for document QA are provided. In various embodiments, a system can generate, via a foundation model, a hypergraph comprising nodes and hyperedges, wherein the nodes represent entities in an information source, wherein the hyperedges represent relationships between two or more of the nodes, and wherein the hyperedges are associated with respective probabilistic weights. In various cases, the system can further select, from the hyperedges, a set of coherent hyperedges for a natural language question that represents coherent information from the information source.
Claims20
A system, comprising:
- a memory that stores computer executable components;
- and
- a processor that executes at least one of the computer executable components that:
- generates, via a foundation model, a hypergraph comprising nodes and hyperedges, wherein the nodes represent entities in an information source, wherein the hyperedges represent relationships between two or more of the nodes, and wherein the hyperedges are associated with respective probabilistic weights;
- and
- selects, from the hyperedges, a set of coherent hyperedges for a natural language question that represents coherent information from the information source.
A computer-implemented method, comprising:
- generating, by a system operatively coupled to a processor and via a foundation model, a hypergraph comprising nodes and hyperedges, wherein the nodes represent the entities, wherein the hyperedges represent relationships between two or more of the nodes, and wherein the hyperedges are associated with respective probabilistic weights;
- and
- selecting, by the system and from the hyperedges, a set of coherent hyperedges for a natural language question that represents coherent information from the information source.
A computer program product for extracting coherent information from an information source, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
- generate, by the processor and via a foundation model, a hypergraph comprising nodes and hyperedges, wherein the nodes represent the entities, wherein the hyperedges represent relationships between two or more of the nodes, and wherein the hyperedges are associated with respective probabilistic weights;
- and
- select, by the processor and from the hyperedges, a set of coherent hyperedges for a natural language question that represents coherent information from the information source.
