Detailed Description
The present disclosure is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 illustrates an exemplary system architecture 100 to which a method for acquiring information or an apparatus for acquiring information of an embodiment of the present disclosure may be applied.
As shown in fig. 1, a system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is used as a medium to provide communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
The user may interact with the server 105 via the network 104 using the terminal devices 101, 102, 103 to receive or send messages or the like. Various information collection applications, such as image collection applications, identification applications, device information query applications, instant messaging tools, mailbox clients, social platform software, etc., may be installed on the terminal devices 101, 102, 103.
The terminal devices 101, 102, 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices supporting information gathering, including but not limited to cameras, tablets, cell phones, card readers, laptop and desktop computers, and the like. When the terminal devices 101, 102, 103 are software, they can be installed in the above-listed electronic devices. Which may be implemented as multiple software or software modules (e.g., to provide distributed services), or as a single software or software module, without limitation.
The server 105 may be a server providing various services, such as a server providing support for respective information collected by the terminal devices 101, 102, 103. The server may receive the respective information collected by the terminal devices 101, 102, 103, and fuse the respective information to obtain fused information corresponding to a specified target (for example, may be a certain user).
It should be noted that, the method for acquiring information provided by the embodiments of the present disclosure is generally performed by the server 105, and accordingly, the apparatus for acquiring information is generally provided in the server 105.
The server may be hardware or software. When the server is hardware, the server may be implemented as a distributed server cluster formed by a plurality of servers, or may be implemented as a single server. When the server is software, it may be implemented as a plurality of software or software modules (for example, to provide a distributed service), or may be implemented as a single software or software module, which is not specifically limited herein.
It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for obtaining information according to the present disclosure is shown. The method for acquiring information includes the steps of:
in step 201, each of a plurality of information collecting apparatuses collects at least one piece of initial information of a specified target.
In the present embodiment, the execution subject of the method for acquiring information (e.g., the server 105 shown in fig. 1) may acquire at least one piece of initial information from the terminal devices 101, 102, 103 by wired connection or wireless connection. Wherein the terminal devices 101, 102, 103 may be information collecting devices distributed in different geographical spaces. It should be noted that the wireless connection may include, but is not limited to, 3G/4G connections, wiFi connections, bluetooth connections, wiMAX connections, zigbee connections, UWB (Ultra Wideband) connections, and other now known or later developed wireless connection means.
The prior art can collect various different types of information through various information collecting devices. However, the number of types of information acquired by the information acquisition apparatuses is limited, and the data formats may also be different between the information acquired by the different information acquisition apparatuses. Although the information collected by different information collecting devices can be fused in a bridging mode, a bridging node is needed when the information is fused. Therefore, some information without direct association cannot be identified through bridging, and partial information cannot be fused easily. And the bridging mode is not easy to directly understand the information fusion process, so that the difficulty of information fusion is increased. Therefore, the information fusion collected by a plurality of information collecting devices is not easy to realize in the prior art.
Before the information is fused, the execution body of the application can establish information connection with the information acquisition devices (namely, the terminal devices 101, 102 and 103) in various modes so as to acquire at least one piece of initial information acquired by each information acquisition device. Wherein each of the plurality of information collection devices collects at least one piece of initial information of the specified target.
The information fusion is carried out aiming at a specific appointed target. Wherein the specified target may be a specified certain user. For example, when a user acquires different initial information from a plurality of information acquisition devices, the execution subject of the present application may fuse the information acquired from the plurality of information acquisition devices, thereby acquiring fused information corresponding to the user. Similarly, the execution subject may implement fusing of the initial information for each specified user.
And 202, constructing an information relation diagram through the at least one piece of initial information.
After obtaining at least one piece of initial information of the plurality of information acquisition devices, the execution subject may first construct an information relationship graph according to the initial information acquired by each information acquisition device. The information relation graph can be used for representing the association relation between at least one piece of initial information acquired by the information acquisition equipment. For example, the information acquisition device may be a security inspection detection device, and the security inspection detection device may query information of a plurality of electronic devices carried by a user. While facial images of the user may be acquired. Thus, the facial image of the user and other acquired information can be constructed into an information relationship graph. The information relationship graph can characterize the association between the various information of the user. The information fusion of the initial information acquired by the single information acquisition equipment is realized.
In some optional implementations of this embodiment, the constructing an information relationship graph by using the at least one piece of initial information may include: and taking the initial information as a node, and connecting the initial information with the association relationship through a line to obtain an information relationship graph.
In order to facilitate construction of the information relationship graph, the execution subject may connect the initial information having the association relationship through a line with the initial information as a node. Thus, the interrelationship among the information is clarified, and the interpretability of the construction of the information relation graph is improved. Wherein the association relationship may be an inherent relationship between the initial information. For example, the initial information may be a cell phone number and an Imei code. When the information acquisition device acquires initial information of a user, the mobile phone number and the Imei code are acquired at the same time, and the mobile phone number and the Imei code are related to the user. At this time, the execution subject may consider that the mobile phone number and the Imei code have an association relationship.
For example, the information acquired by each of the information acquisition apparatuses 1 to 5 is shown in fig. 3. Wherein (1), (2) and (3) are the initial information. The connection line between the initial information indicates that the two initial information of the connection have an association relationship.
In some optional implementations of this embodiment, the constructing an information relationship diagram by using the at least one piece of initial information may further include: and in response to the existence of the subgraph in the information relation graph, carrying out information fusion on the subgraph through the reference data corresponding to the specified target.
As can be seen from the above description, the executing body may have some initial information (such as the mobile phone number and the Imei code described above) with obvious association relation. In practice, the information collection device may collect a plurality of initial information of the same user, which do not have obvious association relation. For example, the initial information may be a cell phone number, an Imei code, an identification card number, etc. The mobile phone number and the Imei code have a clear association relationship. And the mobile phone number and the identity card number have no clear association relation. At this time, when the information relation graph is constructed, a case of a sub-graph occurs. The sub-graph may include a part of initial information in at least one piece of initial information acquired by the corresponding information acquisition device. When the subgraph appears, the association relation cannot be built in all of the plurality of initial information acquired by the information acquisition equipment.
Therefore, the execution subject of the application can inquire the reference data, and the sub-graph is subjected to information fusion through the reference data. The reference data may be user information collected by a mechanism with higher reliability. For example, the reference information may be a user's identification number, cell phone number, fingerprint, gender, age, etc. The execution main body can establish the association relation between the initial information acquired by the information acquisition equipment according to the reference data, so that the information fusion of the subgraphs is realized. For example, in the mobile phone number, the Imei code and the identification card number, the mobile phone number and the Imei code form a sub-graph, and the identification card number also forms a sub-graph (a sub-graph containing only one initial information). The reference data acquired by the executing body can be an identification card number, a mobile phone number, a fingerprint, gender, age and the like of the user, and the reference data are all relevant to the user. At this time, the executing body can form an information relation diagram by the mobile phone number, the Imei code and the identity card number through the reference data.
The association relationship between the initial information in fig. 3 is modified by the reference data, as shown in fig. 4.
And 203, fusing a plurality of information relation diagrams corresponding to the plurality of information acquisition devices to obtain fused information corresponding to the specified target.
From the above description, it is clear that the information collected by different information collecting devices may be different. The above describes the process that the information acquisition device constructs an information relationship diagram for at least one initial information acquired by itself, so as to realize information fusion. And then, the execution main body can fuse the information relation diagrams corresponding to all the information acquisition devices to obtain fusion information of the designated targets. Thus, information fusion of a plurality of information acquisition devices can be realized, and fusion information can be finally obtained. Thus, the information fusion of the initial information acquired by the plurality of different information acquisition devices is realized in a graph fusion mode.
In some optional implementations of this embodiment, the fusing the plurality of information relationship graphs corresponding to the plurality of information collecting devices to obtain the fused information corresponding to the specified target may include the following steps:
first, at least one piece of common initial information among the plurality of information relationship graphs is queried.
In order to establish the association relationship between different information relationship graphs and realize information fusion, the execution subject can firstly inquire the public initial information between the information relationship graphs. Wherein the common initial information may be at least two information relationship graphs existing in the plurality of information relationship graphs. That is, the common initial information is initial information common to at least two information relationship graphs.
And secondly, fusing the plurality of information relation diagrams based on the at least one piece of public initial information to obtain fused information corresponding to the specified target.
After the public initial information is determined, the execution main body can establish the association relation between the initial information in the plurality of information relation diagrams according to the public initial information, realize information fusion of the plurality of information relation diagrams in a diagram fusion mode, and finally obtain fusion information.
The acquisition of common initial information and fusion information on the basis of fig. 4 is shown in fig. 5.
In some optional implementations of this embodiment, the fusing the plurality of information relationship graphs based on the at least one common initial information to obtain the fused information corresponding to the specified target may include the following steps:
The first step, the initial information in at least two information relation graphs associated with the at least one public initial information is associated with the at least one public initial information as a starting point, and an initial fusion graph corresponding to the at least one public initial information is obtained.
There may be a plurality of common initial information. For each common initial information, the execution subject may fuse with the common initial information as a starting point. Specifically, the execution subject may fuse initial information in at least two information relationship graphs corresponding to the common initial information with the common initial information as a starting point, to obtain an initial fusion graph. For example, a common initial message corresponds to two message relationship graphs. The initial information contained in the two information relationship diagrams may be: information relation fig. 1 is: information 1-information 2-information 3-information 4; information relation fig. 2 is: information 5-information 6-information 7-information 3. Wherein information 3 is common initial information. The executing body can fuse the information relation graph with the starting point of the information 3 to obtain an initial fusion graph. The initial fusion map may contain three information chains: first information chain: [ information 3-information 4]; second information chain: [ information 3-information 2-information 1]; third information chain: [ information 3-information 7-information 6-information 5]. Wherein "-" may be used to indicate that two initial information of a connection have an association relationship.
In practice, different information acquisition devices may acquire the same initial information, and when an initial fusion map is obtained through common initial information, a situation that one initial fusion map includes a plurality of pieces of same initial information may occur. At this time, the execution body may retain only one initial information among the repeated initial information. The association relation of the deleted other repeated initial information can be recursively deduced. For example, a certain information chain is: [ information 3-information 7-information 6-information 5]. However, when the duplicate initial information "information 6" needs to be deleted, the information chain after deleting the "information 6" is as follows: [ information 3-information 7-information 5]. The "information 5" is an association relationship established with the "information 7" in a recursive manner.
In practice, it may also occur that the related information relationship diagram has a plurality of pieces of common initial information. At this time, the execution subject may further acquire the confidence of the common initial information. Wherein the confidence level is used to characterize the reliability of the common initial information. And then fusing by taking the public initial information with high confidence as a starting point. The confidence level may be related to the type of initial information. For example, when the public initial information is an identification card number and a mobile phone number. At this time, the executing body can consider that the executing degree of the identification card number is higher than that of the mobile phone number. Then, the executing body can associate with the identification card number as a starting point.
And secondly, merging at least one initial fusion graph into a fusion graph, and obtaining fusion information corresponding to the specified target according to the fusion graph.
Common initial information typically does not appear in all information relationship diagrams at the same time. That is, the initial fusion map obtained is typically a plurality. At this time, the execution body may further merge (i.e., map fusion) the plurality of initial fusion maps to obtain a fusion map. The initial information in the fusion map is the fusion information corresponding to the specified target.
In some optional implementations of this embodiment, the merging at least one initial fusion graph into a fusion graph, and obtaining fusion information corresponding to the specified target according to the fusion graph may include the following steps:
and a first step of constructing at least one piece of virtual information corresponding to at least one fusion sub-graph in response to the existence of the at least one fusion sub-graph.
The initial information in the fusion graph can have an association relationship with each other, and initial information which cannot be associated with other initial information to form a complete information chain can also exist. That is, there may be a fusion subgraph within the fusion graph. At this time, the execution subject opens and constructs virtual information to establish the association relationship of the initial information between the fusion subgraphs. The virtual information may be used to establish an association relationship of initial information between the at least one fusion sub-graph.
As shown in fig. 5, the fusion information in the fusion graph has a fusion subgraph, such as a fusion subgraph formed by initial information in two dotted circles in the fusion graph. At this time, the execution subject may construct virtual information based on the fused subgraph.
And step two, correlating the at least one piece of virtual information with the at least one fusion sub-graph to obtain fusion information.
After the virtual information is constructed, the execution main body can establish the association relation of the initial information among the plurality of fusion sub-images through the virtual information to obtain the fusion information. That is, the fusion information at this time establishes an information chain after the association relationship for all the initial information acquired by the plurality of information acquisition devices.
In some optional implementations of this embodiment, the constructing at least one virtual information corresponding to the at least one fusion sub-graph may include the steps of:
and a first step of inquiring the position information of each piece of initial information in at least one piece of initial information contained in the at least one fusion subgraph.
In practice, different information collecting devices are often distributed in different physical spaces, i.e. the information collecting devices have position information. In order to establish the association relationship of the initial information in the fused sub-graph, the execution subject may first acquire the position information of each initial information in the fused sub-graph.
And a second step of calculating at least one distance value corresponding to the initial information in the at least one fusion subgraph according to the position information.
The fusion subgraph comprises a plurality of initial information and a plurality of corresponding position information. The execution body may calculate the distance value between the position information every two.
And thirdly, constructing initial information corresponding to the distance value smaller than the set distance threshold value in the at least one distance value as virtual information.
The smaller the distance value, the closer the two information acquisition devices are in practice. The information acquisition devices generally acquire a large amount of initial information of users, the time for acquiring the initial information of the designated target by different information acquisition devices is shorter, and correspondingly, the correlation of the initial information of the designated target acquired by each information acquisition device is larger. That is, when there is a distance value smaller than the set distance threshold between the fusion subgraphs, a plurality of initial information corresponding to the distance value may be constructed as virtual information.
It should be noted that, after the association relationship between the initial information in the fusion sub-graph is established through the virtual information, a plurality of initial information in the fusion sub-graph corresponding to the virtual information will be replaced by the virtual information. The corresponding association relationship is transferred from the corresponding plurality of initial information to the virtual information.
As shown in fig. 6, the execution body can construct virtual information by calculating distance values, determining initial information numbered 9, 15, and 17. Wherein the initial information numbered 9 comes from the information acquisition device 3; the initial information numbered 15 comes from the information acquisition device 4; the initial information numbered 17 comes from the information acquisition device 5. The positions of the information acquisition device 3, the information acquisition device 4, and the information acquisition device 5 in practice are explained to satisfy the distance threshold. Thereafter, virtual information X is constructed from the initial information numbered 9, 15, and 17. The other initial information having an association with the initial information numbered 9, 15, and 17 has an association with the virtual information X.
With continued reference to fig. 7, fig. 7 is a schematic diagram of an application scenario of the method for acquiring information according to the present embodiment. In the application scenario of fig. 7, the terminal devices 101, 102, 103 send the initial information collected respectively to the server 105. The server 105 constructs the initial information into corresponding information relationship maps in units of information acquisition devices, respectively. Finally, the server 105 fuses the information relationship graphs to obtain fusion information.
The method provided by the embodiment of the present disclosure firstly obtains at least one piece of initial information collected by a plurality of information collecting devices; then constructing an information relation diagram through at least one piece of initial information, and realizing information fusion of the initial information acquired by the single information acquisition equipment; and finally, fusing a plurality of information relation diagrams corresponding to the plurality of information acquisition devices to obtain fused information corresponding to the specified target. The application realizes the information fusion of the initial information acquired by a plurality of different information acquisition devices in a graph fusion mode.
With further reference to fig. 8, a flow 800 of yet another embodiment of a method for obtaining information is shown. The process 800 of the method for obtaining information includes the steps of:
at step 801, each of a plurality of information collecting apparatuses collects at least one piece of initial information of a specified target.
The content of step 801 is the same as that of step 201 and will not be described in detail here.
Step 802, constructing an information relation diagram through the at least one piece of initial information.
The content of step 802 is the same as that of step 202 and will not be described in detail here.
Step 803, fusing a plurality of information relationship graphs corresponding to the plurality of information acquisition devices to obtain fused information corresponding to the specified target.
The content of step 803 is the same as that of step 203 and will not be described in detail here.
Step 804, in response to receiving an information query request corresponding to a specified target, obtaining target information corresponding to the information query request according to the fusion information.
When the execution body receives the information query request corresponding to the specified target, the execution body can acquire the fusion information of the specified target according to the information query request, and query the information specified by the information query request from the fusion information.
