Embodiment 1
Present embodiment provides a kind of acquisition methods of traffic event information, can specifically be used to collect the event information of traffic aspect, and of Fig. 1, this method mainly comprises:
Step 101 is obtained event information through at least one data source, and by different cities the said event information that obtains is classified.
In the present embodiment, this at least one data source can be specially: traffic control department, the webpage that event information is provided that web crawlers searches, and manual service.
Correspondingly, step 101 can realize through following three kinds of modes:
With reference to Fig. 2, when said data source be web crawlers search the webpage of event information is provided the time;
201, the webpage of event information is provided through web crawlers search;
202, from the Word message of said webpage extraction traffic aspect;
203, the Word message that extracts is resolved to independent vocabulary;
204, according to the fuzzy matching rule said terminology match is become first event information, and the said event information that obtains is classified by different cities;
For instance, for less unnecessary data amount, guarantee data accuracy; Web crawlers is only to particular Web page, and like the traffic control webpage in each city, North China high speed webpage etc. is searched for; Manyly be used to decorate webpage or with the irrelevant code of traffic event information etc.,, like the Word message that from Beijing traffic control webpage, extracts the traffic aspect be: because all can exist in the source code of each webpage for the safety assurance during National Day so need from these source codes, extract the Word message of traffic aspect; 1 evening 9 of October point-12 point, so-and-so street does not allow to pass through etc., can this literal information analysis be become independent one by one vocabulary through Chinese automatic word-cut such as increase income; And according to terminology match such as evening, afternoon are become PM; To not allow to pass through, terminology match such as restricted driving become the fuzzy matching rule conversion that no through traffic to form first event information, and this first event information is gone into Beijing according to the city branch; Particular content can be: the safety assurance during National Day; October 1 the PM9-12 point, so-and-so street, no through traffic.
Further, because different webpages is to the record of same event information, the standard of description is different; Therefore though can occur is same event information but record, the mode of description is various, and event information is unfavorable for searching and managing like this; Therefore for event information is carried out unified management; After obtaining first event information,, can respectively first event information be changed according to unified logout form according to first transformation rule with reference among Fig. 2 205.
For example: unified logout form is: 1: city title, 2: event time 3: incident reason, 4: traffic measure, 5: place etc.First transformation rule that logout form that should be unified is formulated for Beijing traffic control webpage can be: the city title is placed on 1: after, event time is placed on 2: after, the incident reason is placed on 3: after, the traffic measure is placed on 4: after.Correspondingly,, after first event information conversion be: 1 according to the form of above-mentioned logout: Beijing, the 2:10 month 1 the PM9-12 point, 3: the safety assurance during National Day, 4: no through traffic, 5: so-and-so street etc.
