AskMe：Joint Individual-level and Community-level
The AskMe algorithm utilizes techniques such as multi-view, Bi-LSTM, and attention to effectively integrate the imbalanced multi-behavior of users and similar behavior of group users, guiding efficient detection of rare behaviors.

Description： To address the issue of imbalanced user behavior in existing community question-answering systems, as well as the large number of unanswered questions, AskMe explores the construction method of a multi-behavior prediction model for users in sparse and imbalanced situations. The AskMe algorithm effectively integrates the imbalanced multi-behavior of users and similar behavior of group users, guiding efficient detection of rare behaviors. The algorithm takes as input a sequence of a user’s follow, like, and answer behaviors and outputs whether the user answered a given question.
