Component for semantic information annotation

For the recovery of information semantic web techniques are used that enrich the information by extracting knowledge and making annotations. This article proposes a component for making semantic annotations in indexed documents, which uses the content stored in a domain ontology to perform semantic annotations. Natural language processing algorithms are used in the semantic annotation process to improve the quality of the stored information. Accuracy and completeness metrics allowed to corroborate the quality, pertinence and relevance of semantic annotations in information retrieval
