Techopedia Explains Named-Entity Recognition

Named-entity recognition is a state-of-the-art intelligence system that works with nearly the efficiency of a human brain. The system is structured in such a way that it is capable of finding entity elements from raw data and can determine the category in which the element belongs. The system reads the sentence and highlights the important entity elements in the text. NER might be given separate sensitive entities depending on the project. This means that the NER system designed for one project may not be reused for another task. Similarly, NER faces many challenges which include the extraction of correct information for specific but closely related categories.
