Abstract: The new Electronic Commerce Law clarifies the algorithm liability of platform designing, deploying and using algorithms, which includes the obligation of implication, supply of the un-customized searching result, and protection of customers in recommendation and search algorithms. The algorithm liability is making a progress in algorithm's status and role. However, it inevitably shows limitation on practical challenges. The core of algorithm liability should balance the wide gap of powers between platforms and customers. There are some steps to improve the algorithm liability.
