NLP stands for Natural Language Processing, which is a field of computer science and artificial intelligence that focuses on the interaction between human language and computers. It involves the development of algorithms and computational models that enable machines to understand, interpret, and generate human language.

NLP is used in a variety of applications such as language translation, sentiment analysis, speech recognition, chatbots, and text-to-speech systems. NLP also plays an important role in data science, machine learning, and deep learning, as it provides the ability to analyze and understand large volumes of unstructured data, such as text and speech.

LAIF research in NLP is focused on developing methods for extracting information from multiple unstructured sources and fusing them to build a common situational picture.
