Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The embodiment of the invention provides a method for generating a common access path of a node, which comprises the steps of generating the common access path of the given node by analyzing the subsequent access behavior of the reserved user of the given node, and optimizing the access path of the given node through the common access path. The node in the embodiment of the invention refers to a function node in software such as a website or an APP.
As shown in fig. 1, the method for generating a common access path of a node provided by the present invention includes: step 101 to step 103. In step 101, each access path of all the remaining users of a given node in a first time period to access the given node is obtained, and an access path list is generated.
In the invention, the reserved user is a user who accesses the given node in the second time period and accesses the given node again in the first time period, and the first time period and the second time period are not overlapped. The given node is a pre-designated basic node for counting user retention, a first time period and a second time period are predefined time intervals, the time of the second time period is before the first time period, and if a user visits the given node in the second time period and visits the given node again in the first time period, the user is defined as the user retention of the given node. The first time period and the second time period may be one week, one month, one quarter, or even longer if computing resources allow, and are not limited herein.
For example, the method provided by the invention is used for optimizing the access path of the 'guess-you-like' function node of the APP, and the 'guess-you-like' function node is the given node. In this step, firstly determining the remaining users of the "guess you like" functional node, if the second time period is the first quarter of 2016 and the first time period is the second quarter of 2016, determining the access user group of the functional node in the first quarter of 2016 according to the user identifier of the APP access user, and then, if there is a behavior of accessing or clicking again in the user group, and the user still using the "guess you like" module is the remaining user of the "guess you like" functional node.
In this step, an access path for each persistent user to access the given node in the second time period is obtained, where the access path also includes multiple access paths for the persistent user to access the given node multiple times in the second time period. In the invention, every two nodes adjacent to each other in front and back of an access path are defined as an access pair, and in one access pair, the former node is the former node of the access pair, and the latter node is the latter node of the access pair.
For example, one access path is: a1-a2-a3-a4-a5, wherein a1, a2, a3, a4 and a5 are nodes in the path, and the access pairs of the path are a1-a2, a2-a3, a3-a4, a4-a5, and a1 and a2 are front nodes and back nodes of a1-a2 respectively.
In step 102, counting the number of occurrences of the first access pair of each access path in the access path list in the list, sorting the first access pair of each access path according to the number of occurrences from large to small, and selecting the first n access pairs, where n is a set positive integer.
For example, the access path list generated in one step 101 includes four access paths for user 1 to user 4 to access a given node a 5:
the access path for user 1 is a1-a2-a3-a4-a5,
the access path for user 2 is a1-a2-a4-a5,
the access path for user 3 is a1-a3-a4-a5,
the access path for user 4 is a1-a2-a4-a5,
the first access pair of the access paths for user 1, user 2 and user 3 are all a1-a2, and the first access pair of the access path for user 3 are a1-a 3. The number of occurrences in the list of access pair a1-a2 is 3 and the number of occurrences in the list of access pair a1-a3 is 1, so the access pairs obtained by step 102 are sorted as a1-a2, a1-a 3.
In the invention, the access path is configured with a session label, and when the time interval between two consecutive accesses of a retention user to a given node is not more than a preset time, the access paths of the two consecutive accesses are configured as the same session label. That is, from the time when the user enters the website to the time when the user leaves the website, the interval between two consecutive visits to the node does not exceed a predetermined time (generally defined as 30 minutes in the practical application process, which is not limited in the present invention), the two visits of the user are counted as one session, and the two visits with the time interval exceeding the predetermined time are counted as two sessions respectively. The session label configured for the access path in the invention indicates the session to which the access path belongs, all the access paths corresponding to the access behavior in one session have the same session label, and the session labels of the access paths corresponding to the access behaviors of different sessions are different.
In step 102, counting the number of occurrences of the first access pair in the list for each access path in the access path list specifically includes: and counting the occurrence times in the list according to the first access pair of each access path of the session label, counting the occurrence times in the list through the rearrangement when one access pair appears in a plurality of paths with the same session label, and counting the occurrence times directly without performing the rearrangement when the access pair appears in a plurality of paths with different session labels.
As shown in fig. 1 and fig. 2, in step 103, sequentially performing the following steps a to d for each of the selected n access pairs, by which n access paths starting from the selected n access pairs are obtained through analysis, where the n access paths are the paths with the most accesses of the remaining user group of the given node, and after further performing path optimization on the n access paths, the optimization of the access path for the given node in the website or software can be achieved.
In step 103, step a is first executed, and the access pair is taken as the current access pair and stored, that is, each access pair in the access pair sequence obtained in step 102 is taken as the current access pair in turn. As illustrated in step 102, the access pairs are ordered as a1-a2 and a1-a3, so the access pair a1-a2 is now taken as the current access pair and saved, then the subsequent steps b to d are performed, and after step d is completed, the access pair a1-a3 is taken as the current access pair, and the subsequent steps c to d are performed again.
And b, counting the occurrence times of each access pair taking the rear node of the current access pair as the front node in the access path list, and taking the access pair with the maximum occurrence times as an intermediate access pair and storing the intermediate access pair. As in the above example, the access path list is:
a1-a2-a3-a4-a5，
a1-a2-a4-a5，
a1-a3-a4-a5，
a1-a2-a4-a5，
the current access pair is a1-a2, the following node is a2, the access pair with the following node of the current access pair as the preceding node, i.e. the access pair with a2 as the preceding node, is: a2-a3 and a2-a4, counting a2-a3 and a2-a4, the occurrence frequency of the access pair a2-a3 is 1, the occurrence frequency of the access pair a2-a4 is 2, so that the access pair a2-a4 is taken as an intermediate access pair and saved, and then step c is performed.
In the present invention, step b, counting the number of occurrences of each access pair in the access path list, which takes the rear node of the current access pair as the front node, includes: and according to the session label, carrying out re-counting on the occurrence times of each access pair taking the rear node of the current access pair as the front node in the list. In the same manner as the rearrangement counting in step 102, if an access pair appears in a plurality of paths having the same session label, the number of occurrences in the above path in the access pair is rearranged to 1, and conversely, if the access pair appears in a plurality of paths having different session labels, the number of occurrences is counted without performing the rearrangement.
And c, when the rear node of the intermediate access pair is not the given node, taking the intermediate access pair as the current access pair, and executing the step b. As in the example above, the middle access pair a2-a 4's successor node is not the given node a5, so step b is performed with a2-a4 as the current access pair.
In step b, the number of occurrences in the access path list of each access pair with the rear node a4 of the current access pair a2-a4 as the front node is counted, in the example, the access pair with the front node a4 is only a4-a5, and a4-a5 is taken as an intermediate access pair and saved by counting sorting, and then step c is executed.
In step c, the intermediate access is a given node to the rear node a5 of a4-a5, so step d is performed without going to step b.
Step d, concatenating all the access pairs saved in steps a to c to generate a common access path of the given node, as in the above example, the access pairs are saved in the execution process of steps a to c: a1-a2, a2-a4 and a4-a5, and the saved access pairs are connected in series to generate a common access path a1-a2-a4-a5 of a given node a 5.
Step d also comprises path optimization of the common access path. In the present invention, the path optimization of the common access path in step d includes: unnecessary nodes in the common access path are removed to shorten the distance of the common access path. The obtained common access path is analyzed, and because the access path is fixed after the user uses the specific function node, the fixed access path can be analyzed, whether the access path can be simplified or not is considered, whether a single node in the analysis path can be removed or not is analyzed, so that the previous node can directly reach the next node, the user can reach the final given node at the fastest speed, and therefore, enough stay time is kept at the final given node, and the effect of optimizing the access path of the given node is achieved.
And d, after the step d is executed, returning to the step a to repeatedly execute the steps a to d for the next access pair in the sequence. As in the example above, access pairs are ordered as a1-a2, a1-a3, and after steps a through d have been performed for access pair a1-a2, steps a through d are performed for access pair a1-a 3. And d, after all the first n access pairs in the list are subjected to the steps a to d, obtaining n common access paths of the given node, and optimizing the n common access paths. In the actual application process, after 10 access paths are optimized generally, the optimization of the remaining user access path of a given functional node can be considered to be optimal, and certainly, according to the method provided by the invention, more access paths can be continuously analyzed and optimized.
According to the method for generating the common access path of the node, the reserved user of the given node is determined, the access path of the reserved user for accessing the given node is further obtained, then the access path of the reserved user is analyzed, the most frequent access path of the reserved user is obtained, and the access path of the given node is optimized based on the most frequent access path. The subsequent access behaviors of the reserved users of the functional nodes of the website and the software are fully mined, and the access path of the specific functional node is simplified according to the access habits of the reserved users, so that the reserved users can access the specific functional node more quickly, the user stickiness of the website and the software is improved, the reserved users can continuously reserve the specific functional node, greater value is brought, and the fine operation of the website and the software is realized.
An embodiment of the present invention further provides a device for generating a common access path of a node, as shown in fig. 3, the device includes: the system comprises a list generation module 1, an access pair selection module 2 and a common path generation and optimization module 3.
