Concept Hierarchies

An information handling system comprising:

• one or more processors;
• a memory coupled to at least one of the processors;
• a set of instructions stored in the memory and executed by at least one of the processors to generate concept hierarchies, wherein the set of instructions are executable to perform actions of:
• generating, by the system, at least a first concept set comprising one or more concepts extracted from one or more content sources;
• receiving, by the system, a user request to produce a hierarchy of concepts from the first concept set using one or more specified hierarchy parameters;
• generating or retrieving, by the system, a vector representation of each of the concepts in the first concept set;
• performing, by the system, a natural language processing (NLP) analysis comparison of the vector representation of each of the concepts in the first concept set to determine a similarity measure for each pair of distinct concepts Ci and Cj in the first concept set;
• constructing, by the system, a concept hierarchy based on the one or more specified hierarchy parameters and the similarity measure for each pair of distinct concepts Ci and Cj in the first concept set;
• and
• displaying, by the system, the concept hierarchy to visually present a hierarchical structure conveying concept grouping of concepts from the first concept set to enable user navigation over the first concept set.

A computer program product stored in a computer readable storage medium, comprising computer instructions that, when executed by an information handling system, causes the system to generate concept hierarchies by performing actions comprising:

• generating, by the system, at least a first concept set comprising one or more concepts extracted from one or more content sources;
• receiving, by the system, a user request to produce a hierarchy of concepts from the first concept set using one or more specified hierarchy parameters;
• generating or retrieving, by the system, a vector representation of each of the concepts in the first concept set;
• performing, by the system, a natural language processing (NLP) analysis comparison of the vector representation of each of the concepts in the first concept set to determine a similarity measure for each pair of distinct concepts Ci and Cj in the first concept set;
• constructing, by the system, a concept hierarchy based on the one or more specified hierarchy parameters and the similarity measure for each pair of distinct concepts Ci and Cj in the first concept set;
• and
• displaying, by the system, the concept hierarchy to visually present a hierarchical structure conveying concept grouping of concepts from the first concept set to enable user navigation over the first concept set.
