Identifying and invoking applications based on data in a knowledge graph

A computer system comprising:

• a data processing unit;
• a data storage system;
• and
• executable program code stored in the data storage system, which when executed by the data processing unit causes the data processing unit to:
• receive a search input to search for content;
• based on terms contained in the search input, identify one or more first-level nodes from among a plurality of first-level nodes that comprise a graph, wherein the graph represents relationships among information from which the content is being searched;
• based on the terms contained in the search input, identify one or more filters to filter the content being searched for;
• based on the one or more first-level nodes and the one or more filters, identify a selected application from among a plurality of applications;
• and
• invoke the selected application.

A computer-readable storage medium having stored thereon program code, which, when executed by a data processor, causes the data processor to:

• receive a search input to search for content;
• based on terms contained in the search input, identify one or more first-level nodes from among a plurality of first-level nodes that comprise a graph, wherein the graph represents relationships among information from which the content is being searched;
• based on the terms contained in the search input, identify one or more filters to filter the content being searched for;
• based on the one or more first-level nodes and the one or more filters, identify a selected application from among a plurality of applications, wherein each application among the plurality of applications is associated with one or more entities, wherein identifying a selected application includes matching the identified entities with the one or more entities associated with said each application;
• and
• invoke the selected application.
