WantWords, originally known as 万词王, is an innovative reverse dictionary system that uniquely supports both Chinese and English cross-language queries. Developed by the esteemed Natural Language Processing Laboratory at Tsinghua University, this platform leverages state-of-the-art artificial intelligence and natural language processing algorithms to help users find words by describing their meanings. WantWords offers a comprehensive suite of features, including the ability to filter searches by part of speech, sort results based on various criteria, and seamlessly switch between Chinese and English dictionaries.
