and 240, counting the covering quantity of the combined label covering events according to the labels of the event data for each combined label.
And matching the event data with the tag combination, if the tags of the event data comprise all the tags in the combined tags, determining that the event data are covered by the combined tags, and determining the number of the event data covered by each combined tag as + 1.
And step 250, determining feature combination labels according to the event coverage quantity aiming at the combination labels with the same preset label quantity, and determining an event coping strategy through the feature combination labels.
The feature combination tags reflect main influence factors of events, and at least one combination tag with the total quantity meeting a set total quantity lower limit condition and the difference meeting a set difference lower limit condition is selected as a feature combination tag corresponding to the number of the preset tags according to the event coverage number of each combination tag with the same number of the preset tags, and corresponding measure suggestions are matched on the feature combination tags. For example, the number of fire events is 1000, and through statistics, if the number of event data meeting the combination of staff, market and heavy label is 500, which accounts for half of the total number of events and is far larger than the number of event data meeting other label combinations, the staff, market and heavy label are determined as feature combination labels and matched with suggestions, such as: strengthening fire-fighting knowledge training of staff in a shopping mall; if the number of event data conforming to the combination of staff, shopping mall and heavy label is 300, the number of event data conforming to student, school and light is 300 and is far greater than the number of event data conforming to other label combinations, the two combined labels are determined as feature combined labels, and matching suggestions are provided, such as: and the fire-fighting knowledge training of staff in a shopping mall and students in a school is enhanced.
For example: relevant factors affecting a fire event include: the number of smokers or the temperature is high, whether the additional factors and the number of fire events have a linear relation or not is analyzed, if the additional factors and the number of fire events have the linear relation, suggestions are given, and if the additional factors and the number of fire events have the linear relation, the suggestions are given, such as: the linear relation between the number of smokers and the number of fighting events exists, and as the number of smokers increases, the number of fire events also increases, and then the matching suggestions are shown, such as: smoking is prohibited in schools, and fire checks in schools and fire reminders to students are enhanced on wednesday.
The method for processing event data includes the steps of firstly obtaining event data, identifying content of the event data, matching tags according to the content of the event data, combining the tags to obtain one or more combined tags, counting the number of the combined tags covering events, then determining a feature combined tag according to the event coverage number in the combined tags with the same preset number of tags, matching an event handling strategy to the feature combined tag, after determining the feature combined tag, performing distribution statistics on time tags in the event data according to a preset time period to determine a time distribution feature of the event data of the feature combined tag, matching the event handling strategy, and introducing additional factors on the basis of the feature combined tag containing the time feature to determine the event handling strategy.
