The difference between HowNet Library and HowNet lies in the different document types. HowNet database contains Chinese and English documents and documents in other languages on the Internet, while HowNet refers to the Chinese database of HowNet, which only contains Chinese documents and no documents in other languages. In addition to the essential differences, the number of documents collected will also be different. Because the number of Chinese documents is very large compared with that of English documents, the number of documents included in HowNet's Chinese database is far greater than that of foreign databases.
