Query: A Summary of the ALQAC 2021 Competition   We summarize the evaluation of the first Automated Legal Question Answering
Competition (ALQAC 2021). The competition this year contains three tasks, which
aims at processing the statute law document, which are Legal Text Information
Retrieval (Task 1), Legal Text Entailment Prediction (Task 2), and Legal Text

that can automatically determine whether a particular statement is lawful.
There is no limit to the approaches of the participating teams. This year,
there are 5 teams participating in Task 1, 6 teams participating in Task 2, and
5 teams participating in Task 3. There are in total 36 runs submitted to the

results, and some discussion about the competition. Only results of the teams
