What is semantic extraction?
Semantic extraction refers to extracting the meaning of a document, preferably in a (semi-)automated way. Part of semantic extraction are the following processes: recognizing and extracting named entities and keywords, analyzing the sentiment of a document, extracting facts and relation between those facts and named entities, categorizing documents, recognizing and extracting concepts and finally adding them as metadata or annotations.
