The various embodiments herein provide a method and a system for building an entity hierarchy. The method comprises extracting a plurality of entities from a bin data, determining a parent entity by understanding a context in which the entity is used, resolving the entities by bringing the synonymous entities together and holding the polysemous entities apart based on a semantic context and a syntactic context and building a hierarchical structure of entities using knowledge repositories, ontologies and language repositories along with natural language processing techniques. The method of extracting entities from the structured data comprises identifying each data point as an entity and identifying entities based on a relationship defined with other entities. The method of extracting entities from unstructured data includes a self-learning process and training based learning process to learn new parent entities from domain specific documents using new entity recognition models. |
