Information Extraction is a field of study within computer science that focuses on the automatic retrieval of specific types of information from text. This involves tasks such as identifying named entities, determining relationships between these entities, and classifying or categorizing the extracted information. It is a crucial component of Natural Language Processing (NLP), a wider discipline that deals with the interaction between computers and human language. Cogniverses, on the other hand, relate to the creation of cognitive, artificial intelligence-powered universes of knowledge, which can greatly benefit from the techniques of Information Extraction, thus making it possible to extract and structure knowledge from vast amounts of unstructured data.
