AI knowledge base, which uses the theory of neural network of the human brain imitating the and pattern and structure of foreign languages learning and memorizing and foreign language translation knowledge memorizing of human brains, including word bank (entry), sentence bank (sentential pairs, sentence patterns and sentence forms) and neural network (data/ information) that associates word bank and sentence bank and defines morphology and syntax. Every pattern and structure saved in the sentence bank constructs a grammatical pattern/model, which can realize computer intelligent translation processing of analyzing, comparing, reasoning and speculating etc.

The described sentence pattern/form is case-based, and it is a translation example as well as a translation mode and translation sentence form, therefore, it can do word-based exact match translation as well as sentence pattern match translation and sentence form match translation.

The advantage of AI knowledge base is the generalization of sentence bank structure and the intelligence of translation knowledge memory.

According to translation language, AI knowledge base can be classified into various types, such as: English-Chinese, Japanese-Chinese, German-Chinese, Chinese-English, Chinese-Japanese, and Chinese-German etc.

In the case of a pair of translation languages, AI knowledge base can be classified by profession, such as: English-Chinese Machinery AI Knowledge Base, English-Chinese Computer AI Knowledge Base and Chinese-English Law AI Knowledge Base.
