What is a reverse dictionary ? An ordinary dictionary tells you the definition of a word , The reverse dictionary is just the opposite , It can tell you which words match the meaning of the description you enter . The following is a screenshot of wanciwang online reverse dictionary , It demonstrates an example of reverse word lookup , input “ The mountain is very high ”, The system will return a series of model representations “ The mountain is very high ” Meaning words , for example “ Gao Jun ”,“ Towering ” etc .

besides , It also supports Chinese , English , Chinese-English , There are many different ways of transformation, such as English and Chinese .

The overall system architecture is also very simple :

Wan ciwang's core model was the natural language processing laboratory of the computer department of Tsinghua University (THUNLP) Published in AAAI-20 A multi-channel reverse dictionary model proposed in a paper on :Multi-channel
Reverse Dictionary Model [ paper ] [ code ], The model architecture is shown below :
