Detailed Description

The following description is based on the illustrated embodiments of the present application and should not be taken as limiting other embodiments not described in detail herein. The term "module" as used herein may be considered as a software object executing on the computing system. The various modules, engines, and services herein may be viewed as implementation objects on the computing system.

The embodiment of the application provides a method for determining a hot event, and an execution subject of the method for determining a hot event may be a hot event determining device provided by the embodiment of the application, or an electronic device integrated with the hot event determining device. Wherein the electronic device may be a server or the like.

Specific analysis is described below.

Referring to fig. 1, fig. 1 is a first flow chart of a method for determining a hot event according to an embodiment of the present application, where the method for determining a hot event may include the following steps:

101. And receiving a search request, determining a search text and a request moment according to the search request, and extracting a first keyword from the search text.

In the embodiment of the application, after receiving the search request of the client, the electronic device may determine a request time of the search request, analyze the search request, obtain a search text, and extract a keyword from the search text as the first keyword, in addition to returning the search content to the client according to the search request. It will be appreciated that the client is installed in a user terminal, which establishes a communication connection with an electronic device acting as a server.

Wherein one search request corresponds to one search text. The search text is text entered by the user in the client search field. After receiving the search text input by the user in the search bar, the client generates a search request according to the search text, and then sends the search request to the electronic equipment so that the electronic equipment returns search contents according to the search request.

The request time of the scheme may refer to the time when the client sends the search request, or may refer to the time when the electronic device receives the search request.

In addition, the extraction manner of the keywords is not particularly limited in the embodiments of the present application. For example, the electronic device may analyze the search text by a keyword extraction algorithm, and extract one or more terms from the search text as the first keywords.

102. And counting first retrieval times of the first keyword in a first preset time period from the request time, and judging whether the first retrieval times meet a first preset condition.

In the embodiment of the application, after determining the search text and the request time according to the search request and extracting the first keyword from the search text, the electronic device may use the search text in the search request received in the first preset time period from the request time as a statistical object to count the number of search texts with the first keyword. Then, the number of search texts is used as a first search number of the first keyword within a first preset time period from the request time. Then, whether the first search times meet the first preset condition is judged, if yes, the execution is continued 103 if the first keyword is likely to be a hot spot keyword, and if not, the first keyword is judged not to be a hot spot keyword.

For example, assuming that the first preset duration is 4 minutes, the electronic device a receives a search request at 10 points, determines that the search text in the search request is "double eleven shopping benefits" and the request time is 10 points, and extracts the first keyword "shopping benefits" from the "double eleven shopping benefits". The electronic device A takes the search text in the search request received in the 10-point to 10-point 4-period as a statistical object. And then counting the number of search texts with the shopping benefits, taking the number of search texts as the first search times of the shopping benefits in a first preset time period from the request time, and judging whether the first search times of the shopping benefits meet a first preset condition. If the first search count of "shopping benefits" satisfies the first preset condition, the "shopping benefits" may be hot keywords, and execution continues at 103. If the first search times of the shopping benefits do not meet the first preset condition, the shopping benefits are not determined to be hot keywords.

The first preset duration of the solution may be a duration preset in the electronic device, such as 5 minutes, 4 minutes, 3 minutes, and so on. The first preset duration of the scheme can also be a duration obtained by the electronic device in real time according to the historical hot event.

The first preset condition is preset in the electronic equipment. The first preset condition may be set manually, or may be set by the electronic device according to a certain rule.

The first search times satisfying the first preset condition may refer to a first keyword having a first search time greater than a first threshold, where the first search times satisfy the first preset condition. Or alternatively

The first search times satisfying the first preset condition may refer to a first target keyword whose ranking satisfies the first preset ranking in the ranking of the plurality of first target keywords, where the first search times satisfy the first preset condition. The first target keywords refer to first keywords, wherein the first retrieval times of the first keywords are larger than a second threshold value. Or alternatively

The first search times satisfying the first preset condition may refer to a second target keyword whose ranking satisfies a second preset ranking in ranking of a plurality of second keywords, where the first search times satisfy the first preset condition. The second target keyword refers to a first keyword, of the one or more first keywords, of which the first retrieval times are larger than a third threshold value. The plurality of second keywords are keywords extracted by the electronic device according to the plurality of search texts received within a first preset time period from a request time, and the request time refers to a request time of extracting the search text (1) of the first keywords. That is, from the reception time point of view, the search text for extracting the first keyword is the first search text of the plurality of search texts for extracting the plurality of second keywords. Thus, the first keyword is included in the plurality of second keywords.

103. If yes, obtaining second retrieval times of the first keyword in a first preset duration before the request time.

In the embodiment of the application, after determining that the first search times meet the first preset condition, the electronic device uses the search texts in the search request received in the first preset time before the request time as a statistical object to count the number of the search texts with the first keyword. Then, the number of the search texts is used as the second search times of the first keyword in the first preset time before the request time. It should be noted that the first search number of the first keyword at the time of performing this operation has satisfied the first preset condition.

For example, following the above example of "double eleven shopping benefits", after judging that the first search number of times of "shopping benefits" satisfies the first preset condition, the electronic device a takes as a statistical object the search text in the search request received during the 9 th to 10 th points 56. Then counting the number of search texts with 'shopping benefits', and taking the number of search texts as the second search times of the 'shopping benefits' in the first preset time before the request time.

104. And judging whether the search increment condition of the first keyword meets a second preset condition according to the first search times and the second search times.

In this embodiment of the present application, after obtaining the first search times and the second search times of the first keyword, the electronic device may determine a search growth condition of the first keyword according to the first search times and the second search times, and then determine whether the search growth condition of the first keyword meets a second preset condition, if yes, then the execution is continued 105 if the first keyword meets all conditions of the hot spot keyword, and if not, determine that the first keyword is not the hot spot keyword. The second preset condition is a numerical value preset in the electronic equipment. The second preset condition may be set manually, or may be set by the electronic device according to a certain rule.

Note that, the embodiment of the present application is not particularly limited as to the manner of searching for the growth condition in this scenario.

In some embodiments, when determining the search growth of the first keyword according to the first search times and the second search times, the electronic device may calculate the growth rate of the first keyword according to the first search times and the second search times, and use the growth rate as the search growth of the first keyword.

Wherein, R represents the growth rate of the first keyword, M1 represents the first retrieval times of the first keyword, M2 represents the second retrieval times of the first keyword, and the calculation formula of the growth rate is as follows:

In some embodiments, when determining the search growth of the keyword according to the first search number and the second search number, the electronic device may calculate a difference between the first search number and the second search number, and use the difference as the search growth of the first keyword.

Wherein V represents a difference value of the first keyword, M1 represents a first search number of the first keyword, M2 represents a second search number of the first keyword, and the difference value has the following calculation formula:

V＝M1-M2

105. if yes, taking the first keywords meeting the second preset conditions as hot spot keywords, acquiring events corresponding to the hot spot keywords, and determining that the events are hot spot events.

In the embodiment of the present application, after determining that the search growth condition of the first keyword meets the second preset condition, the electronic device uses the first keyword as a hotspot keyword, acquires an event corresponding to the hotspot keyword, and determines that the event is a hotspot event. The hot event is mainly presented in the form of a short sentence, and the hot event comprises the hot key word. The hotspot event and the search text for extracting the first keyword are similar in content and may be the same or different.

It can be understood that the first search times of the hot key word satisfy the first preset condition, and the search increase condition thereof satisfies the second preset condition.

As can be seen from the above, in the embodiment of the present application, when a search request is received, since the search times and the search growth condition are used as evaluation indexes to determine whether the first keyword extracted from the search text of the search request is a hotspot keyword, and further determine whether the event corresponding to the hotspot keyword is a hotspot event, the identification accuracy of the hotspot event can be improved.

In some embodiments, before counting the first number of searches of the first keyword within the first preset time period from the request time, the electronic device may further perform:

determining the type of a search text, and acquiring the types of a plurality of historical hot events;

matching the type of the search text with the types of the plurality of historical hot events, and taking the successfully matched historical hot event as a second target historical hot event;

and calculating the average hotspot determination time length according to the hotspot determination time length of the second target historical hotspot event, and taking the average hotspot determination time length as a first preset time length.

In the scheme, after determining a search text according to a search request, counting first search times of a first keyword in a first preset duration from a request time, the electronic device can determine the type of the search text, acquire the types of a plurality of historical hot events, and take the historical hot events with the same type as the search text in the plurality of historical hot events as second target historical hot events, wherein the type of the historical hot events is the same as the type of the search text, and then judging that the two historical hot events are matched. Then, the electronic device acquires the hotspot determination duration of the second target historical hotspot event, calculates the average hotspot determination duration, and takes the average hotspot determination duration as the first preset duration.

Wherein, the historical hot event is an event that the electronic device has determined to be a hot event prior to the time of the request. Each historical hotspot event includes at least one hotspot keyword. The hotspot determination duration of each historical hotspot event refers to a period from a request time of the search request for determining that the event is a hotspot event to a time for determining that the event is a hotspot event.

In addition, the embodiments of the present application are not particularly limited with respect to the type of the search text and the type of the history hot event. For example, the type of the search text includes an entertainment type, a natural disaster type, and the like.

It should be noted that, the first preset duration in the scheme is counted by the historical hot events with the same type as the search text, so that the setting of the first preset duration is more reasonable, and the identification accuracy of the hot events is improved.

In some embodiments, after acquiring an event corresponding to a hotspot keyword and determining that the event is a hotspot event, the electronic device may search the information base for push content matching the hotspot event, and set the push content on the recommendation interface. For example, the electronic device may set push content matching the hotspot event on the recommendation interface for a preset time (e.g., 5 minutes). The successfully matched push content may refer to the content with the highest matching degree, or the successfully matched content may refer to the content with the highest matching degree, the second highest matching degree, or the like.

Referring to fig. 2, fig. 2 is a second flowchart of a method for determining a hot event according to an embodiment of the present application, where the method for determining a hot event may include the following steps:

201. and receiving a search request, determining a search text and a request moment according to the search request, and extracting a first keyword from the search text.

In the embodiment of the application, after receiving the search request of the client, the electronic device may determine a request time of the search request, analyze the search request, obtain a search text, and extract a keyword from the search text as the first keyword, in addition to returning the search content to the client according to the search request. Wherein the search text is text entered by the user in the client search bar. The request time may refer to a time when the client transmits the search request, or may refer to a time when the electronic device receives the search request.

In some embodiments, upon extracting the first keyword from the search text, the electronic device may remove invalid characters in the search text; and performing word segmentation and stop word removal on the search text from which the invalid characters are removed to obtain a first keyword. Wherein, the invalid characters of the search text comprise emoji characters, space characters, messy code characters and the like. Stop words are words or characters that are automatically filtered after processing natural language text in order to increase retrieval efficiency. The stop words are mainly divided into functional words and vocabulary words, and functional words such as "yes", "and the like have no actual meaning words or words.

202. The life time of a plurality of historical hot events is obtained.

In the embodiment of the application, after determining the search text and the request time according to the search request and extracting the first keyword from the search text, the electronic device may acquire the life time lengths of the plurality of historical hot events. Wherein, the historical hot event is an event that the electronic device has determined to be a hot event prior to the time of the request. Each historical hot event has a respective life duration, and the life durations between two historical hot events may be the same or different.

It should be noted that the historical hot events can be divided into two categories: events that are still hot events at the time of the request, events that are not hot events at the time of the request. The life duration acquisition modes of the two types of historical hot events are different. For the event which is still a hot event at the request moment, the electronic device acquires the moment of determining the event as the hot event, namely, the starting moment, and determines the time from the starting moment to the request moment as the life duration of the event. For an event which is not a hotspot event at the request time, the electronic device acquires the time when the event is determined to be the hotspot event, namely the starting time, and the time when the event is removed from the hotspot event, namely the ending time, and determines the time from the starting time to the ending time as the life duration of the event.

203. And taking the historical hot events with the life time longer than the second preset time as the first target historical hot events.

In the embodiment of the present application, after acquiring the life time lengths of a plurality of historical hotspot events, the electronic device uses, as a first target historical hotspot event, a historical hotspot event with a life time length longer than a second preset time length in the plurality of historical hotspot events. The second preset duration is preset in the electronic device, and the second preset duration can be manually adjusted.

In some embodiments, after acquiring the life durations of the plurality of historical hotspot events, the electronic device may further use a historical hotspot event with a life duration within a first preset range in the plurality of historical hotspot events as the third target historical hotspot event. And then calculating the average hotspot determination time length according to the hotspot determination time length of the third target historical hotspot event, and taking the average hotspot determination time length as a first preset time length. The first preset range is preset in the electronic equipment, and the first preset range can be manually adjusted.

204. And calculating the average hotspot determination time length according to the hotspot determination time length of the first target historical hotspot event, and taking the average hotspot determination time length as a first preset time length.

In this embodiment of the present invention, after taking a history hotspot event with a life time longer than a second preset time as a first target history hotspot event, the electronic device may obtain respective hotspot determination time lengths of the first target history hotspot event, so as to obtain a plurality of hotspot determination time lengths. And then calculating the average hotspot determining duration of the plurality of hotspot determining durations, and taking the average hotspot determining duration as a first preset duration.

Wherein each historical hotspot event comprises at least one hotspot keyword. The hotspot determination duration of each historical hotspot event refers to a period from a request time of the search request for determining that the event is a hotspot event to a time for determining that the event is a hotspot event.

In some embodiments, before taking the average hotspot determining duration as the first preset duration, the electronic device may further determine whether the average hotspot determining duration is greater than a set value, if so, take the set value as the first preset duration, and if not, take the average hotspot determining duration as the first preset duration. The set value is a maximum value of a first preset duration set in the electronic device, for example, the set value may be 5 minutes.

205. And counting first retrieval times of the first keyword in a first preset time period from the request time, and judging whether the first retrieval times meet a first preset condition.

In this embodiment of the present application, after determining the first preset duration, the electronic device may use, as a statistical object, the search text in the search request received in the first preset duration from the request time, and count the number of search texts having the first keyword. Then, the number of search texts is used as a first search number of the first keyword within a first preset time period from the request time. Then, it is determined whether the first search number satisfies a first preset condition, if yes, then the first keyword is likely to be a hot spot keyword, and if not, then it is determined that the first keyword is not a hot spot keyword, then 206 is executed.

In some embodiments, when determining whether the first search number of times satisfies the first preset condition, the electronic device may determine whether the first search number of times is greater than a first threshold, where it is determined that the first search number of times satisfies the first preset condition when the first search number of times is greater than the first threshold.

It should be noted that, in this solution, the first threshold is preset in the electronic device. The first search times meeting the first preset condition means that a first keyword with the first search times being larger than a first threshold value exists.

For example, assume that the first preset time period is 3 minutes, the search text of one search request is "national celebration reader", and the request time is 12 points. The keyword extracted from the national celebration reader is the reader. The electronic equipment acquires 700 search requests received in 12-12 points 3 and determines 700 search texts of the 700 search requests. Then, the number of search texts with "reader" in the 700 search texts is counted and used as the first search times of "reader". And then, the electronic equipment judges whether the first search times of the 'reading soldier' are larger than a first threshold value, if so, the first search times of the 'reading soldier' are judged to meet a first preset condition, if not, the first search times of the 'reading soldier' are judged to not meet the first preset condition, and the 'reading soldier' is not a hot spot keyword.

In some embodiments, if there are a plurality of first keywords, when determining whether the first search times meet the first preset condition, the electronic device may determine, as the first target keyword, a first keyword whose first search times are greater than a second threshold value from the plurality of first keywords, where the first target keyword is a plurality of first target keywords; and sorting the plurality of first target keywords according to the first search times, and judging that the first search times of the first target keywords with the ranking meeting the first preset ranking in the sorting meet the first preset condition.

The second threshold and the first preset ranking are preset in the electronic equipment. The first target keyword is a first keyword whose first search number is greater than a second threshold value.

For example, assume that the first preset time period is 3 minutes, the search text of one search request is "XXX and YYY officers are wedding", and the request time is 13 points. The keywords extracted from "XXX and YYY officials" are "XXX", "YYY" and "wedding", i.e. the first keywords are "XXX", "YYY" and "wedding". The electronic equipment acquires 500 search requests received in 13-13 points 3 and determines 500 search texts of the 500 search requests. Then, the number of search texts having "XXX" among the 500 search texts is counted as the first search number of "XXX". Similarly, the first search times of "YYY" and the first search times of "wedding" are counted. Then, the electronic device determines whether the first search number of times "XXX" is greater than a second threshold, and if yes, determines that "XXX" is the first target keyword. Similarly, whether "YYY" is the first target keyword and whether "wedding" is the first target keyword are determined. When it is determined that "XXX" is the first target keyword, "YYY" is the first target keyword, and "wedding" is the first target keyword, the electronic device ranks "XXX", "YYY" and "wedding" by the first search number. If the first target keywords with the ranking meeting the first preset ranking in the ranking are XXX and wedding, the electronic equipment judges that the first retrieval times of XXX and wedding meet the first preset condition and judges that the first retrieval times of YYY do not meet the first preset condition, namely the YYY is not a hot spot keyword.

In some embodiments, when counting the first search times of the first keyword within a first preset time period from the request time and judging whether the first search times meet a first preset condition, the electronic device may acquire a plurality of search requests received within the first preset time period from the request time, and determine a plurality of search texts of the plurality of search requests; counting the number of search texts with first keywords in the plurality of search texts, wherein the number of the search texts is used as the first search times of the first keywords in a first preset time period from a request moment; determining a first keyword with the first retrieval times being larger than a third threshold value as a second target keyword, and extracting a plurality of different second keywords from the plurality of retrieval texts, wherein the plurality of second keywords comprise the first keyword; and sorting the plurality of second keywords based on the search times, and judging that the first search times of the second target keywords with the ranking meeting the second preset ranking in the sorting meet the first preset condition, wherein the plurality of second keywords comprise the second target keywords.

For example, assume that the first preset time period is 3 minutes, the search text of one search request is "XXX and YYY officers are wedding", and the request time is 13 points. The keywords extracted from "XXX and YYY officials" are "XXX", "YYY" and "wedding", i.e. the first keywords are "XXX", "YYY" and "wedding". The electronic device acquires 500 search requests received in 13-13 points 3, and determines 500 search texts of the 500 search requests, wherein the search texts of the ' XXX and YYY officers ' wedding ' are the first search texts in the 500 search texts according to the receiving time. Then, the number of search texts having "XXX" among the 500 search texts is counted as the first search number of "XXX". Similarly, the first search times of "YYY" and the first search times of "wedding" are counted. Then, the electronic device determines whether the first search number of times "XXX" is greater than a third threshold, and if yes, determines that "XXX" is the second target keyword. And similarly, judging whether YYY is a second target keyword and judging whether wedding is a second target keyword. When the XXX is judged to be the second target keyword, the YYY is judged to be the second target keyword and the wedding is judged to be the second target keyword, the electronic equipment extracts keywords of the determined 500 search texts to obtain 100 different second keywords. Among the 100 different second keywords, 3 keywords of "XXX", "YYY" and "wedding" are included. For each second keyword, the number of search texts having it among 500 search texts is counted as the number of search times. And then sorting the 100 second keywords according to the search times. If the second target keywords with the ranking meeting the second preset ranking in the ranking are XXX and wedding, the electronic equipment judges that the first search times of XXX and wedding meet the first preset condition and judges that the first search times of YYY do not meet the first preset condition, namely the YYY is not a hot spot keyword.

The third threshold and the second preset ranking are preset in the electronic equipment. The second target keyword refers to a first keyword whose first search number is greater than a third threshold value. The plurality of second keywords are a plurality of different keywords extracted by the electronic device according to the plurality of search texts received within a first preset time period from the request time.

In addition, the embodiment of the present application is not specifically limited as to the extraction manner of the second keyword. For example, the electronic device may analyze the plurality of search texts through a keyword extraction algorithm, and extract one or more word keywords from each search text, resulting in a plurality of different second keywords. Any two second keywords are different from each other.

The request time is the request time of the search text (1) from which the first keyword is extracted. That is, from the reception time point of view, the search text for extracting the first keyword is the first search text of the plurality of search texts for extracting the plurality of second keywords. Therefore, the plurality of second keywords include the first keywords and keywords other than the first keywords.

206. If yes, obtaining second retrieval times of the first keyword in a first preset duration before the request time.

207. And judging whether the search increment condition of the first keyword meets a second preset condition according to the first search times and the second search times.

Note that, the embodiment of the present application is not particularly limited as to the manner of searching for the growth condition in this scenario. For example, the search growth condition is represented by the growth rate of the first keyword, or the like.

208. If yes, taking the first keywords meeting the second preset conditions as hot spot keywords, acquiring events corresponding to the hot spot keywords, and determining that the events are hot spot events.

In some embodiments, when acquiring an event corresponding to a hotspot keyword, the electronic device may acquire a plurality of search requests received within a first preset duration from a request time, and determine a plurality of search texts of the plurality of search requests; taking a search text with a hot keyword in the plurality of search texts as a target search text; and generating an event corresponding to the hot spot keyword according to the target retrieval text.

For example, assuming that the first preset duration is 5 minutes, the search text of a certain search request is "GGG officer announces wedding" and the request time is 18 points, 700 search texts are received from 18 points to 18 points 5, and the keywords "GGG" and "wedding" extracted from the search texts are determined as hot spot keywords. The electronic device can take a plurality of pieces of search texts with GGG and wedding in 700 search texts as target search texts, and generate topic information corresponding to the multi-item target search texts according to a document topic generation model so as to represent events corresponding to GGG and wedding. For example, "GGG and DDD officers announce weddings.

209. Searching a plurality of push contents matched with the hot events in an information base.

In the embodiment of the present application, after determining that the event corresponding to the hotspot keyword is a hotspot event, the electronic device may match the hotspot event with the push content in the information base, and obtain a plurality of push contents successfully matched with the hotspot event. It will be appreciated that the information base of the electronic device stores a large amount of push content, which is mainly information uploaded by other devices that establish a communication connection with the electronic device.

210. And acquiring the basic weights and the hot point weights of the plurality of push contents, and calculating the recommendation scores of the push contents according to the basic weights and the hot point weights.
