Abstract: A robot is provided. The robot includes a sensor, a driver, a communication interface, and a processor configured to acquire first context data through the sensor, receive second context data acquired by at least one other robot through the communication interface, identify at least one context data of the first context data and the second context data based on a collaboration scenario of the robot and the other robot, input the identified at least one context data to a predetermined task allocation algorithm related to the collaboration scenario to acquire task information corresponding to the robot, and control the driver based on the acquired task information.

Abstract: Disclosed is a method of extracting and using a semantic entity from a text message by an electronic device. The method includes: recognizing a text-based input; extracting a semantic entity from the text-based input; and providing the extracted semantic entity through an application in response to the application having a semantic setting that corresponds to the extracted semantic entity.

Abstract: When a communication occurs in an electronic device, groups are automatically generated according to the user's situation by: storing a communication history in a database; generating a first group from the database on the basis of the time and location information stored in the database at a predetermined time; retrieving a transmission list from the database and generating a second group from the database on the basis of an identifier of an opposing party included in the transmission list; retrieving a reception list from the database and generating a third group from the database on the basis of an identifier of an opposing party included in the reception list and the identifier of the opposing party included in the transmission list; and generating a fourth group on the basis of the information commonly included in at least two groups of the first group, the second group and the third group.

Abstract: A method of determining a second application related to a first application being executed by using a use log of a portable terminal and executing the second application according to a user input and an apparatus for supporting the same are provided. The portable terminal may determine the second application related to the first application being executed, based on a use log collected in a previous context state identical or similar to a current context state of a user. At this time, in order to determine the current context state of the user, the portable terminal may use information related to a location of the portable terminal and information related to a current time.
