All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, a flowchart of a hot microblog sorting method according to an embodiment of the present invention is shown, where the method includes:
s101: and acquiring the blogger information, the blog information and the interaction information of the blog of the real-time blog.
As shown in fig. 2, the interaction information of the blog is the number of interactions of the users to the blog, including the number of comments and the number of endorsements to the blog.
S102: and determining the hot blog meeting the set quality requirement in the specific field according to the blog information and the blog information.
Specifically, as shown in fig. 3, extracting the blog main information of the real-time blog and keywords in the blog information, and judging whether the real-time blog belongs to the blog in a specific field or not through keyword matching;
regarding the blogs determined to belong to the specific field, according to the keywords of the blogs information of the blogs, the blogs meeting the set quality requirements, such as no reaction information such as politics and yellow, no advertisement information and content including only pure numbers, pure links and the like, are determined as the hot blogs.
S103: and determining the popularity value of each hot blog according to the determined release time and interaction information of each hot blog.
And carrying out heat value calculation on the microblog text at fixed time, wherein a cooling strategy along with time and an interactive heating strategy are involved. Specifically, as shown in fig. 4, for each hotbox:
determining the time temperature of the hot blog according to the release time of the hot blog, wherein the time temperature represents the blog Wen Redu related to the blog release time, the time temperature decreases along with the increase of the release time of the blog, namely, the temperature is reduced along with the time by utilizing Newton's law of cooling through a cooling strategy, and the temperature is calculated according to the Newton's law of cooling:
T'(t)＝-α(T(t)-H)
the method is characterized by comprising the following steps of solving a calculus equation to obtain:
this is the end result we want: the current time temperature T (T) =the last time temperature T t-1 X exp (- (cooling coefficient) x hours of interval).
For example, in the financial field, according to the relevant characteristics of stock information and factors on a microblog platform, relevant parameters are set for a calculation formula as follows:
initial score: the starting scores of all microblog texts from the moment of release are unified to be 100 points;
cooling total time: 48 hours;
score after cooling: 0 minutes;
cooling coefficient: -0.0959;
interval time between two adjacent heat calculations: 10 minutes, i.e. 1/6 hour.
Further, for each hotbox:
determining the interaction temperature of the hot blog according to the interaction information of the hot blogThe interaction temperature represents the blog Wen Redu related to the interaction information of the blog, the interaction temperature is increased according to the interaction of the user on the blog, the content is heated according to the interaction condition of the user on the blog in real time, and the temperature value of the information is increased; the strategy for temperature rise is to maintain several conditions:
(1) Regardless of the heat increase, it still drops to approximately 0 after 48 hours.
(2) With the prolongation of the microblog release time, the influence of the interaction number on the increase of the microblog heat is weakened gradually along with the time, and hardly any influence is generated until the microblog release time is close to 48 hours.
And determining a heat value T of the hot blog according to the time temperature and the interaction temperature.
Preferably, the popularity value T of the hotbox is determined according to the following formula:
wherein,,the time temperature of the hot blog text at the current calculation moment is represented; t (T) t-1 The time temperature of the hot blog at the last calculation moment; e is a natural constant, alpha is a cooling coefficient, t is the current calculation time, and t-1 is the last calculation time.
S104: and sorting the hot blogs according to the heat value of each hot blogs.
