System and method for content-based data visualization using a universal knowledge graph

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry of a computer system to execute a process, the process comprising:

• receiving events by the computer system;
• parsing, by the computer system, each of a plurality of the received events into a plurality of objects, wherein the plurality of events includes a plurality of queries, wherein each event of the plurality of events is related to an interaction with at least one data source;
• determining, by the computer system, for each of the plurality of events, a relationship between two objects of the plurality of objects;
• generating, by the computer system, a semantic knowledge graph based on the determined relationships, the semantic knowledge graph including a plurality of query nodes and a plurality of edges, wherein each query node corresponds to a respective object of the plurality of objects, wherein each query node is connected to another query node of the plurality of query nodes by one of the plurality of edges, wherein each edge represents a relationship between the objects connected by the edge;
• repeating, by the computer system, the receiving, parsing, determining, and generating so as to cause the first semantic knowledge graph to be updated continually over time as events occur;
• assigning, by the computer system, a score to each edge, wherein the score assigned to each edge indicates a weight of the edge, wherein the score assigned to each edge is determined based on a number of appearances of the relationship represented by the edge in the parsed plurality of events;
• generating, by the computer system, an enriched data layer based on a plurality of knowledge graphs including the first semantic knowledge graph, the plurality of knowledge graphs including a plurality of first nodes, the enriched data layer including a plurality of second nodes, wherein each of the plurality of second nodes is connected via an edge to at least one of the plurality of first nodes;
• and
• generating, by the computer system a data visualization based on the enriched data layer and a request for data, wherein the request for data indicates a type of data corresponding to at least one of the plurality of second nodes, wherein the data visualization is generated using data represented by at least one of the plurality of first nodes connected to the at least one of the plurality of second nodes.

A system for generating data visualizations, comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
• parse each of a plurality of received events into a plurality of objects, wherein the plurality of events includes a plurality of queries, wherein each event of the plurality of events is related to an interaction with at least one data source;
• determine for each of the plurality of events, a relationship between two objects of the plurality of objects;
• generate a semantic knowledge graph based on the determined relationships, the semantic knowledge graph including a plurality of query nodes and a plurality of edges, wherein each query node corresponds to a respective object of the plurality of objects, wherein each query node is connected to another query node of the plurality of query nodes by one of the plurality of edges, wherein each edge represents a relationship between the objects connected by the edge;
• repeat the receiving, parsing, determining, and generating so as to cause the first semantic knowledge graph to be updated continually over time as events occur;
• assign a score to each edge, wherein the score assigned to each edge indicates a weight of the edge, wherein the score assigned to each edge is determined based on a number of appearances of the relationship represented by the edge in the parsed plurality of events;
• generate an enriched data layer based on a plurality of knowledge graphs including the first semantic knowledge graph, the plurality of knowledge graphs including a plurality of first nodes, the enriched data layer including a plurality of second nodes, wherein each of the plurality of second nodes is connected via an edge to at least one of the plurality of first nodes;
• and
• generate a data visualization based on the enriched data layer and a request for data, wherein the request for data indicates a type of data corresponding to at least one of the plurality of second nodes, wherein the data visualization is generated using data represented by at least one of the plurality of first nodes connected to the at least one of the plurality of second nodes.
