In some applications, offer the passage of the reporting events relevant to road conditions, to be applied to the navigation Service etc. of electronic chart.
If user finds the event relevant to road conditions, need user to open application, then reported by the control of specifying, operate often more loaded down with trivial details, user's enthusiasm is not high, makes the product of events relevant to road conditions tire out quantity few, upgrade not in time, the navigation Service etc. of electronic chart cannot be applied to.
And developing rapidly along with mobile communication technology, mobile device is also widely used in the every aspect of user's life, such as, and work, study, amusement, friend-making etc.
One of them is applied as social media (Social Media) application, also referred to as social media, social media, refer to the application allowing people to write, share, evaluate, discuss, communicate with each other, such as, immediate communication tool platform, microblogging, blog, forum etc.
User is when encountering this kind of event, and be often open the application of some social media to carry out Information issued, especially mobile device is provided convenience for issuing at any time.
Such as, suppose to construct in Hui Zhong North Road, certain user might release news in social media application, " late! Hui Zhong has constructed in North Road, harmful I around half a day! "
Therefore, the socialization navigation of one of the core idea proposing the embodiment of the present invention, by the strength of users, accumulate the event data in the social media information relevant to road conditions, and these event datas are acted on Map Services, namely user produces content (UGC, user generated content) pattern.
With reference to Fig. 1, show the flow chart of steps of a kind of service processing method embodiment based on electronic chart of the present invention, specifically can comprise the steps:
Step 101, from the social media information grabbed, searches the target social media information relevant to road conditions;
In actual applications, user can be applied by social media, is issued by the server that social media information is sent to platform.
In oneainstance, if social media provides for current platform, then directly social media information can be captured in real time at the server of current platform.
In another scenario, if social media provides for other platforms, then can by the social media information to grab in real time at the interface of other platforms.
It should be noted that, in order to ensure the right of privacy and the right to know of user, first can check whether user adds appointment plan, such as, user's shared programs etc.
If this user adds appointment plan, then confirm that the social media information scratching operation of this user to server is authorized, server can continue to perform the operation of social media information scratching, if this user does not add executive plan, then confirm that this user does not authorize the social media information scratching operation of server end, server stops performing the operation of social media information scratching.
It should be noted that, server can capture social media information in real time, from the social media information grabbed in real time, search the target social media information relevant to road conditions, to make strain to road conditions fast, issue the event relevant to road conditions as early as possible, as traffic hazard etc., be applied in the service of electronic chart.
