Ink and ink will build a model for each word, from "the difficulty of each word", "the difference of each user's memory" and "Has the user touched a word before?" These three dimensions determine the user's mastery of a word, and plan the next memory path accordingly.

The data sources for establishing the model are user's click records, page response time, etc. Like all applications supported by big data algorithms, the accuracy of ink algorithm increases with the increase of users. According to the founder Yue Xiao, nearly 3 million pieces of memory behavior data have been accumulated in the background.

In addition to the memory algorithm, Momo has also made a lot of efforts in the content of the entry:

Each entry has been manually edited and passed the four-fold inspection, so that the example sentences are short and concise, which is helpful to understand the words, and the example sentences will not contain new words that are more difficult than the words themselves. Yue Xiao told me that there are more than 24,000 words in the thesaurus, and the average manual editing time of each entry is about 15 minutes. This part of the work is outsourced to college students.
