Abstract: A system stores resources such as text articles, videos, and so forth for an organization. During operation, the system receives a query and provides a response. During initial use of the system, there is little or no historical data available to help determine which resource is most relevant to a particular query. In this “cold-start” situation, the system determines attributes associated with a user account of the user making the query. The query is used to search a data store and retrieve a set of resources based on a term match with the query and to find the resources which correspond to the attributes of the user account. This allows the system to provide simplified output that is more likely to be relevant to that particular user in the “cold-start” situation.

Abstract: The present disclosure relates to intelligent control technology, and provides a robot, a method for controlling motion of a robot and a non-transitory readable medium. The method includes: acquiring current motion state of the robot; when the robot is in abnormal motion state, storing received data; when the robot returns to normal motion state, acquiring restoring time for the robot to return from the abnormal motion state to the normal motion state; and controlling the robot to perform a corresponding action after the robot returns to the normal motion state. In this way when multiple robots perform synchronized tasks and one of them is interrupted, this robot may perform the corresponding action based on the fault duration and the data which correspond to the action the robot needs to perform in the normal motion state. Thus, this robot may keep its actions consistent with the others.
