1. A method for determining a complex situation, the method comprising the steps of:

  • obtaining, by an apparatus, events occurring in a set of devices among a plurality of devices connected to the apparatus via a network, wherein the events occur at time intervals and are detected by the set of devices, the apparatus includes a database in which complex situation analytic rules are established, the complex situation analytic rules map a plurality of situations onto a plurality of conditions, and each of the plurality of conditions is defined by events occurring in devices of the plurality of devices and time intervals of the events occurring in the devices; and

    determining, by the apparatus, a current situation by referring to a result of obtaining the events occurring in the set of devices in the step of obtaining and a complex situation analytic rule of the complex situation analytic rules,wherein the complex situation analytic rule is a rule which maps the current situation onto a condition included in the plurality of conditions and defined by the events occurring in the set of devices and the time intervals between the events occurring in the set of devices,wherein the plurality of conditions comprise a first detection condition defined by events occurring in a first device, a second device and a third device among the set of devices and time intervals among the events occurring in the first device, the second device and the third device, and each of events of the second device and the third device occurs after an event of the first device occurs,wherein the current situation is determined based on the rule mapping the current situation onto the first detection condition,wherein the first device, the second device and the third device are separate devices, and each of the first device, the second device and third device is connected to the apparatus via the network, andwherein the method further comprises;

    determining, by the apparatus, whether a determination withdrawal condition for withdrawing the determined current situation is satisfied based on an event occurring in the third device and obtained by the apparatus from the third device via the network and one of a time interval between the event occurring in the first device and obtained by the apparatus from the first device via the network and the event occurring in the third device and obtained by the apparatus from the third device via the network and a time interval between an event occurring in the second device and obtained by the apparatus from the second device via the network and the event occurring in the third device and obtained by the apparatus from the third device via the network, andwithdrawing, by the apparatus, the determined current situation according to a result of the determination that the determination withdrawal condition is satisfied.
