Abstract: A story monitoring method when a robot takes an elevator is provided. The method including: obtaining gravity acceleration of the robot in a static state in an elevator and transient acceleration of the robot in a moving state in the elevator, a starting story number, and a story height of each story; obtaining an acceleration change waveform of the robot; comparing the acceleration change waveform by using an acceleration waveform classifier of the elevator, to obtain a movement status of the elevator at each moment; obtaining actual displacement of the elevator in a complete movement status of the elevator; and obtaining a story that the elevator is on after a complete movement status according to the actual displacement of the elevator, the starting story number, and the story height of each story.

Abstract: A method for data retrieval is described. Interface circuitry of an information processing apparatus receives a request for data retrieval from a database. The database stores content sharing information in a social network. The request includes a first user identifier and a first link identifier. The processing circuitry determines whether the first user identifier and the first link identifier are associated in the database as a consequence of a previous sharing of a first article corresponding to the first link identifier using the first user identifier. Further, when the first user identifier and the first link identifier are determined to be associated, the processing circuitry searches for a first message identifier in the database. The first message identifier identifies a first message that includes information of the previous sharing of the first article. The processing circuitry then retrieves the first message according to the first message identifier.

Abstract: The present disclosure provides an, intersection algorithm-based search method and system, and a storage medium, where the search method includes: analyzing search keywords to generate a syntax tree; flattening the syntax tree and selecting a document set having a shortest inverted block as a minimum candidate set; traversing the minimum candidate set and evaluating a traversing result to separately generate a quantity of times of inverted intersections and a quantity of times of sequential intersections; and selecting an intersection algorithm having the less quantity of times as a target intersection algorithm and generating a search result according to the target intersection algorithm.
