Data sparsity refers to the challenge of dealing with datasets where the majority of the elements are zero or missing, which can complicate data analysis and model training. This issue is prevalent in fields like recommender systems and natural language processing, where it can lead to difficulties in extracting meaningful patterns and making accurate predictions.

Natural language processing (NLP) is a field at the intersection of computer science, artificial intelligence, and linguistics, focused on enabling computers to understand, interpret, and generate human language. It encompasses a wide range of applications, from speech recognition and sentiment analysis to machine translation and conversational agents, leveraging techniques like machine learning and deep learning to improve accuracy and efficiency.
