The summary in the conclusion should be distinguished from the abstract and or the overview in the introduction in the sense that it should be conclusive.
First, indicate the overall contribution of your system:
We present YOUR SYSTEM that improves ... YOUR TASK.
Then, conclude the key contributions of specific methods:
Our METHOD shows the state-of-the-art accuracy on ASPECTS.
Our METHOD is found to be more effective in ASPECTS.
If the impact of your work reaches the point that it can make a significant contribution to the field, describe its broader impacts:
Our model allows FIELD to OVERCOME EXISTING CHALLENGES.
Finally, mention how you plan to release relevant resources (if possible):
All our resources including the dataset, models, and source codes are available through our open source project in URL.
The future work in the conclusion should be more explicit than the future directions of discussions in the analysis in the sense that it should specify your next steps of this research.
First, indicate the key challenges that you would address as the next steps:
Despite great peformance, our model still lack in CHALLENGES.
Then, illustrate your plan to handle such challenges:
We plan to tackle CHALLENGES using METHODS.
