All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the method is a flowchart of a method for ranking hot microblogs according to an embodiment of the present invention, and the method includes:
s101: and acquiring the blogger information, the blogger information and the interaction information of the blogger in real time.
As shown in fig. 2, the interaction information of the blog article is the number of user interactions with the blog article, including the number of comments and the number of praise with the blog article.
S102: and determining the popular blog articles meeting the set quality requirement in the specific field according to the blogger information and the blog article information.
Specifically, as shown in fig. 3, the blogger information of the real-time blogger and the keywords in the blogger information are extracted, and whether the real-time blogger belongs to the blogger in the specific field is judged through keyword matching;
and for the blog articles judged to belong to the specific field, judging the blog articles meeting the set quality requirements as the popular blog articles according to the keywords of the blog article information of the blog articles, wherein the set quality requirements comprise that the blog articles do not contain any adverse information such as political relation, yellow relation and the like, do not contain advertisement information, and the content only comprises pure numbers, pure links and the like.
S103: and determining the popularity value of each popular blog according to the determined release time and the interaction information of each popular blog.
And calculating the heat value of the microblog messages at regular time, wherein a temperature reduction strategy along with time and an interactive temperature rise strategy are involved. Specifically, as shown in fig. 4, for each of the trenbologies:
determining the time temperature of the popular blog according to the release time of the popular blog, wherein the time temperature represents the blog popularity related to the blog issue time, the time temperature is reduced along with the increase of the release time of the blog, namely, the temperature is reduced along with the time by using a Newton cooling law through a temperature reduction strategy, and the formula is calculated according to the Newton cooling law:
T'(t)＝-α(T(t)-H)
after solving the calculus equation, the following results are obtained:
this is the end result we want: the time temperature T (T) of the current period is the last time temperature Tt-1X exp (- (cooling coefficient) × 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 initial scores of all the microblog messages from the moment of release are unified to be 100 scores;
total cooling time: 48 hours;
score after cooling: 0 minute;
cooling coefficient: -0.0959;
interval time of two adjacent heat calculations: 10 minutes, 1/6 hours.
Further, for each hit word:
determining the interaction temperature of the popular blog according to the interaction information of the popular blog
The interactive temperature represents the heat of the blog article related to the interactive information of the blog article, the interactive temperature is heated according to the increase of the interaction of the user to the blog article, the content is heated in real time according to the interaction condition of the user to the blog article, and the temperature value of the information is increased; the strategy for temperature increase is to maintain several conditions:
(1) regardless of how much heat is added, it still drops to nearly 0 after 48 hours.
(2) With the prolonging of the microblog release time, the influence of the interaction number on the increase of the microblog popularity gradually weakens along with the time, and almost no influence is caused until the microblog popularity approaches 48 hours.
And determining the heat value T of the popular blog according to the time temperature and the interaction temperature.
Preferably, the heat value T of the trenbology is determined according to the following formula:
wherein the content of the first and second substances,
time temperature of the hot blog at the current calculation time is represented; t ist-1The time temperature of the popular blog article at the last calculation time, e is a natural constant, α is a cooling coefficient, t is the current calculation time, and t-1 is the last calculation time.
S104: and sorting the hit blog articles according to the heat value of each hit blog article.
Corresponding to the above method, as shown in fig. 5, the method is a schematic diagram of a hot microblog ranking device according to an embodiment of the present invention, and the device includes:
the information acquisition unit 21: the system comprises a database, a database server and a database server, wherein the database is used for storing the information of the bloggers and the interaction information of the bloggers;
