Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure 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 disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In one example, fig. 1 is a flowchart of a method for linkage adjustment of a point of interest situation according to an embodiment of the present disclosure, where the embodiment is applicable to a multi-location situation linkage adjustment, and the method may be executed by a device for linkage adjustment of a point of interest situation, where the device may be implemented by at least one of software and hardware, and may be generally integrated in an electronic device. Accordingly, as shown in fig. 1, the method comprises the following operations:
and step 110, when the situation state change of the target interest point is detected, acquiring a target child interest point taking the target interest point as a parent interest point.
The target interest point can be a place which needs information linkage and has a geographic position and a name. Alternatively, the target points of interest may include, but are not limited to, landmark points present in a digital map. Illustratively, the target points of interest may include shops, schools, fast food restaurants, banks, hotels, etc. in the digital map. The present state may be used to reflect the most up-to-date status of the geospatial information provided by the map. The target child point of interest may be a location with a geographic location and name within the target point of interest range as a parent point of interest. The target sub-points of interest may be infrastructure (e.g., north, west, south, north, etc.) in the target point of interest, or may be merchants in the target point of interest.
In the embodiment of the disclosure, the presence state of the target interest point may be detected, and when the presence state of the detected target interest point changes, the target interest point may be further obtained within the target interest point area range, and the target interest point is used as a target child interest point of the parent interest point.
It can be understood that, when the target interest point which is normally operated stops operating, the target interest point which is originally operated is normally operated again, or a new target interest point is generated, the situation status of the target interest point is changed.
And step 120, performing linkage adjustment on the situation state of each target sub interest point according to the parent-child relationship compactness of each target sub interest point and each target interest point.
The parent-child relationship closeness can be used for reflecting the change frequency degree of the target child interest points in the target interest points. Generally, merchants in a store are frequently replaced, infrastructure in the store is not basically changed, and the closeness of parent-child relationships between target child interest points and target interest points can be described by using the change frequency degree of the target child interest points in the store (the closeness of the parent-child relationships between the infrastructure and the store is higher than that between the merchants and the store).
In the embodiment of the present disclosure, the closeness of the parent-child relationship between each target child interest point and the target interest point may be determined according to the change frequency degree of each target child interest point at the target interest point, so as to update the present status of each target child interest point according to the current present status of the target interest point and the closeness of the parent-child relationship between each target child interest point and the target interest point, thereby implementing the linkage adjustment of the present statuses of the target interest point and the target child interest point.
According to the technical scheme of the embodiment of the disclosure, when the situation state change of the target interest point is detected, the target interest point is acquired as the target interest point, and then the situation state of each target interest point is adjusted in a linkage manner according to the closeness of the parent-child relationship between each target interest point and each target interest point. Because the parent-child relationship exists between the target interest point and the target interest point, the situation that the data cannot be updated in time because the situation state of the target interest point is not adjusted when the situation state of the target interest point changes can be avoided by performing linkage adjustment on the situation state of the target interest point according to the parent-child relationship compactness between the target interest point and the target interest point, the problem of high data updating cost existing in the process of carrying out the situation updating on a single target sub interest point can be solved, the problem of poor user travel experience caused by the fact that the situation state of the interest point cannot be updated in time in the prior art is solved, a parent-child linkage strategy can be introduced in the situation of situation change mining of the interest point, better travel experience can be provided for a user, and the data updating cost is greatly reduced.
In an example, fig. 2a is a flowchart of a linkage adjustment method for a probability of occurrence of an interest point provided by an embodiment of the present disclosure, and this embodiment provides an optional implementation manner for establishing parent-child relationship closeness between each child interest point and a parent interest point to which the target interest point belongs before acquiring a target child interest point taking the target interest point as the parent interest point when a probability state change of the target interest point is detected. Accordingly, as shown in fig. 2a, the method comprises the following operations:
and step 210, establishing a parent-child relationship among the interest points according to at least one of the interest point addresses, the interest point longitudes and latitudes and the interest point names of the interest points.
The point of interest address may be a location where the point of interest is located. The point of interest longitude and latitude may be used to describe the geographic coordinates of the point of interest. The point of interest name may be a location name of the point of interest.
In the embodiment of the present disclosure, the address, longitude and latitude, and name of each point of interest may be obtained based on the existing digital map and global positioning technology, and the affiliation relationship between the points of interest is determined according to at least one of the address, longitude and latitude, and name of each point of interest, and then the parent-child relationship between the points of interest is established according to the affiliation relationship between the points of interest.
Step 220, establishing parent-child relationship closeness of each child interest point and the parent interest point to which the child interest point belongs according to the interest point attribute of each child interest point.
The interest point attribute may be a feature of the interest point itself. Optionally, the point of interest attributes include, but are not limited to, a presence status, a point of interest name, a point of interest type, and a presence confidence (i.e., a confidence of the presence status), etc. The situational confidence coefficient can be characterized by available state information (signboard information, comment, reservation information, navigation times and the like) of the interest point, and the state prediction of the interest point is obtained through a known model (such as a GBDT & TCN model and the like). Illustratively, the situational confidence may be represented by a numerical value in the range of 0-1, the higher the numerical value, the more likely the situational state of the point of interest is an outdated state. The disclosed embodiment does not limit the value interval corresponding to the situational confidence and the corresponding relationship between the value and the possibility of the expired state.
In the embodiment of the present disclosure, the change frequency of each child interest point may be determined based on the interest point attribute of each child interest point, so that the parent-child relationship closeness between each child interest point and the parent interest point to which the child interest point belongs is established according to the change frequency of each child interest point. The parent-child relationship between the interest points is determined through the information such as the geographic positions and/or names of the interest points, the accuracy of the parent-child relationship between the interest points can be ensured, and wrong information linkage is avoided.
In an optional embodiment of the present disclosure, establishing parent-child relationship closeness between each child interest point and the parent interest point to which the child interest point belongs according to the interest point attribute of each child interest point may include: matching the interest point attribute of the currently processed sub interest point with an in-region infrastructure element library; if the matching is successful, determining that the closeness of the parent-child relationship between the currently processed child interest point and the belonged parent interest point is strong closeness; and if the matching fails, determining that the closeness of the parent-child relationship between the currently processed child interest point and the belonged parent interest point is weak and tight density.
Wherein, the currently processed child interest point can be a child interest point which needs to determine the closeness of the parent-child relationship with the belonged parent interest point currently. The intra-area infrastructure element library may be a database of infrastructure-related data present within the parent point-of-interest area. Alternatively, the infrastructure element library may include, but is not limited to, infrastructure type, and infrastructure name, etc.
In the embodiment of the present disclosure, a parent interest point to which a currently processed child interest point belongs may be determined first, and then an in-region infrastructure element library matched with the parent interest point is obtained, so that the interest point attribute of the currently processed child interest point is matched with the in-region infrastructure element library. If the current processing child interest point exists in the infrastructure element library in the region, the matching of the interest point attribute of the current processing child interest point and the infrastructure element library in the region is successful, and the closeness of the parent-child relationship between the current processing child interest point and the parent interest point can be determined to be strong closeness. If the current processing child interest point is not in the in-region infrastructure element library, it indicates that the interest point attribute of the current processing child interest point fails to be matched with the in-region infrastructure element library, and it may be determined that the closeness of the parent-child relationship between the current processing child interest point and the belonging parent interest point is weak density. By matching the currently processed sub interest points with infrastructure elements in the region, the parent-child relationship between the interest points with the determined parent-child relationship compactness can be ensured, and information linkage errors are avoided.
And step 230, when the situation state change of the target interest point is detected, acquiring a target child interest point taking the target interest point as a parent interest point.
In the embodiment of the present disclosure, when the business status of the target point of interest is changed from business to closed, it may be detected that the current status of the target point of interest is changed from normal status to expired status. When the business state of the target interest point is changed from off to business, the situation state of the target interest point can be detected to be changed from an expired state to a normal state. And when the target interest point is the generated new interest point, the detected state of the target interest point is a normal state. By detecting the situation state of the target interest point, whether the situation state of the target interest point is changed or not can be determined in time, and accurate information linkage is carried out on the target sub interest point matched with the target interest point.
And 240, performing linkage adjustment on the current state of each target sub interest point according to the parent-child relationship compactness of each target sub interest point and each target interest point.
In an optional embodiment of the present disclosure, performing linkage adjustment on the situation status of each target sub interest point according to parent-child relationship compactness of each target sub interest point and each target interest point may include: identifying a first type of sub interest points with strong parent-child relationship compactness in each target sub interest point; and performing linkage adjustment on the situation state of each first-type sub interest point according to the situation state change result of the target interest point.
The first type of child interest points may be interest points whose parent-child relationship closeness with the target child interest points is strong closeness. The change result of the current situation may be a change result of the current situation of the target point of interest.
In the embodiment of the disclosure, the target sub interest points may be screened according to the closeness of the parent-child relationship between each target sub interest point and each target interest point, so as to obtain the target sub interest points with the strong closeness of the parent-child relationship with the target interest points, as the first type of sub interest points, further obtain the current state change result (such as an expired state or a normal state) of the target interest points, synchronize the current state change result of the target interest points to each first type of sub interest points, implement information linkage adjustment of the target interest points and each first type of sub interest points, and prevent the problem of poor user experience caused by untimely information linkage.
For example, when the business status of the target point of interest is changed from business to off, the current status of the first type of sub-point of interest may be changed from normal status to expired status. When the business state of the target interest point is changed from off to business, the current state of the first type of sub interest point can be changed from an expired state to a normal state. When the target interest point is a new generated interest point, the state of the first type of sub-interest point can be updated to be a normal state.
In an optional embodiment of the present disclosure, detecting that the probability state change occurs in the target interest point may include: detecting that the present state of the target interest point is changed from a normal state to an expired state; performing linkage adjustment on the present status of each target sub-interest point according to the closeness of the parent-child relationship between each target sub-interest point and each target interest point, which may include: identifying a second type of sub interest points with weak and tight parent-child relationship density in each target sub interest point; and performing linkage adjustment on the situation state of each second type of sub interest point according to the situation state change basis of the target interest point.
The second type of interest can be interest points of which the closeness of parent-child relationship is weak tight density in the target interest points.
In the embodiment of the present disclosure, after it is detected that the present state of the target interest point is changed from the normal state to the outdated state, the target interest points may be screened according to parent-child relationship closeness between each target interest point and the target interest point, so as to obtain the target interest points with the parent-child relationship closeness with the target interest point being weak tight density, and the target interest points are used as the second type of interest points. Further, the situation state change basis of the target interest point is obtained, information linkage is carried out on the situation state of each second type of sub-interest point according to the situation state change basis of the target interest point, accurate linkage adjustment of the target interest point and each second type of sub-interest point is achieved, and the problem of poor user experience caused by untimely information linkage is solved.
In an optional embodiment of the present disclosure, the performing the linkage adjustment on the situation status of each of the second type sub interest points according to the situation status change basis of the target interest point may include: and if the situation state change basis of the target interest point is determined to be manual feedback change, the situation state of each second type of sub interest point is adjusted to be an overdue state in a linkage mode.
In the embodiment of the present disclosure, if the present state of the target point of interest is the past due state and the present state change criterion of the target point of interest is changed by the manual feedback, the present state linkage of the second type of sub-point of interest is adjusted to the past due state. Because the accuracy of the information fed back manually is high, when the situation state of the target interest point is determined to be changed through manual feedback, the probability of the change of the situation state of the target interest point is high, the situation state of each second type of sub-interest point and the situation state of the target interest point are changed in a linkage mode, the situation state of the interest point can be updated in time, and the updating accuracy of the situation state can be guaranteed.
In an optional embodiment of the present disclosure, the performing the linkage adjustment on the present status of each of the second type sub interest points according to the present status change basis of the target interest point may include: if the situation state change basis of the target interest point is determined to be model prediction change, calculating the proportion of the second type of sub interest points with the situation states of overdue in all the second type of sub interest points; and if the specific gravity exceeds a preset threshold value, the current state of each second type of sub interest point is adjusted to be an overdue state in a linkage manner.
The threshold value may be a preset proportional value.
In the embodiment of the present disclosure, the current state of the target interest point may be predicted based on a trained model, when the current state of the target interest point is determined to be an expired state according to the model prediction, the proportion of the second type of sub interest points whose current states are the expired state in all the second type of sub interest points may be calculated, and if the proportion exceeds a preset threshold, the current states of the second type of sub interest points are adjusted to be the expired state in a linkage manner.
Due to the fact that the model prediction has error, when the proportion of the second type of sub interest points with the overdue state in all the second type of sub interest points exceeds a preset threshold value, the situation of the situation state of each second type of sub interest point is adjusted to the overdue state in a linkage mode, and the situation that the situation of wrong updating of the situation state of the interest points caused by the model prediction error can be avoided.
Illustratively, the topological relation (parent-child relation between the interest points) of the interest points can be constructed according to the addresses of the interest points and the longitude and latitude of the interest points, and the strong closeness can be identified by using a number 1, and the weak closeness can be identified by using a number 2.
In a specific example, suppose that the point of interest a is mcdonald's (world wide web store), the point of interest B is world wide web-west, and the point of interest C is world wide web, and the three point of interest topological relationships are stored as follows:
key point of interest a (mcdonald (world-wide-forward), value { 'parent point of interest': the interest point C is collected in a ' flag ' 2 ' manner, and the interest point A is a child interest point of the interest point C, and the parent-child relationship compactness of the interest point A and the interest point C is weak compactness. key point of interest B (muster), value { 'parent point of interest': the interest point C is collected in a 'flag' 1 manner, and the interest point B is a child interest point of the interest point C, and the parent-child relationship compactness of the interest point B and the parent-child relationship compactness of the interest point C are strong compactness. key point of interest C (universal sink), value { 'parent point of interest': no, 'flag':0} indicates that the interest point C has no parent interest point.
For example, when the interest point is manually fed back to be closed or is predicted to be closed based on the model (the probability confidence exceeds a set threshold), the probability state of the interest point can be changed from a normal state to an overdue state. And when the name of the interest point is fed back manually or is sensed to be changed through a situational technology, the name of the interest point is changed in real time. For example, when the interest point name of a parent interest point is changed, the addresses of all the child interest points of the interest point and the store names of the names need to be modified.
According to the technical scheme of the embodiment of the disclosure, parent-child relationships among the interest points are established according to at least one of the interest point addresses, the longitude and latitude of the interest points and the interest point names of the interest points, and then the parent-child relationship closeness of each child interest point and the corresponding parent interest point is established according to the interest point attributes of each child interest point, so that when the situation state change of the target interest point is detected, the target child interest point taking the target interest point as the parent interest point is obtained, and further, the situation state of each target child interest point is subjected to linkage adjustment according to the parent-child relationship closeness of each target child interest point and the target interest point. The parent-child relationship between the interest points is determined through the information such as the geographic positions and/or names of the interest points, and the accuracy of the parent-child relationship between the interest points can be ensured. The method has the advantages that the parent-child relationship exists between the target interest point and the target child interest point, the situation of the target child interest point that data cannot be updated in time due to the fact that the situation of the target child interest point is not adjusted in the situation when the situation of the target interest point changes can be avoided by performing linkage adjustment on the situation state of the target child interest point according to the parent-child relationship closeness of the target child interest point and the target interest point, the problem that the data updating cost is high due to the fact that the situation of the target child interest point is not adjusted in the situation of the target interest point can be solved, the problem that the user travel experience is poor due to the fact that the situation of the interest point cannot be updated in time in the prior art is solved, a parent-child linkage strategy can be introduced in the situation change mining scene of the interest point, better travel experience can be provided for the user, and the cost of data updating is greatly reduced.
In an example, fig. 2b is a flowchart of linkage adjustment of a point of interest situational provided by an embodiment of the present disclosure, and as shown in fig. 2b, the method includes:
step 2100, establishing a parent-child relationship among the points of interest according to at least one of the point of interest addresses, the point of interest longitudes and latitudes, and the point of interest names of the points of interest.
Step 2110, matching the interest determination attributes of the currently processed child interest points with the infrastructure element library in the region, if the matching is successful, determining that the parent-child relationship compactness of the currently processed child interest points and the affiliated parent interest points is strong compactness, and if the matching is failed, determining that the parent-child relationship compactness of the currently processed child interest points and the affiliated parent interest points is weak compactness.
And step 2120, identifying the first type of sub interest points with parent-child relationship compactness as strong compactness in each target sub interest point.
And 2130, performing linkage adjustment on the situation states of the first type of sub interest points according to the situation state change result of the target interest point.
Step 2140, in each target sub interest point, a second type of sub interest point with parent-child relationship compactness as weak and tight density is identified.
And step 2150, performing linkage adjustment on the situation state of each second type sub interest point according to the situation state change basis of the target interest point.
In an optional embodiment of the present disclosure, step 2150 may include the steps of, if the situational state change of the target point of interest is changed by human feedback, performing step 2151; if the situational state change criterion is a model prediction change, then steps 2152 and 2153 are performed.
And step 2151, if the situation state change basis of the target interest point is determined to be manual feedback change, adjusting the situation state of each second type of sub interest point to be in an overdue state in a linkage mode.
Step 2152, if it is determined that the change of the situation state of the target interest point is based on model prediction change, calculating the proportion of the second type of sub interest points with the situation state of overdue in all the second type of sub interest points.
And step 2153, if the specific gravity exceeds the preset threshold, adjusting the present state of each second type of sub interest point to an overdue state in a linkage manner.
