Fig. 1 illustrates an exemplary system architecture 100 of a method for obtaining information or an apparatus for obtaining information to which embodiments of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.

The terminal devices 101, 102, and 103 may have various information collecting applications installed thereon, such as an image collecting application, an identity recognition application, a device information query application, an instant messaging tool, a mailbox client, social platform software, and the like.
The terminal apparatuses 101, 102, and 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices supporting information collection, including but not limited to cameras, tablet computers, mobile phones, card readers, laptop portable computers, desktop computers, and the like. When the terminal apparatuses 101, 102, 103 are software, they can be installed in the electronic apparatuses listed above. It may be implemented as a plurality of software or software modules (for example, for providing distributed services), or as a single software or software module, which is not specifically limited herein.
The server 105 may be a server that provides various services, for example, a server that provides support for various information collected by the terminal apparatuses 101, 102, 103. The server may receive each piece of information collected by the terminal devices 101, 102, and 103, and fuse each piece of information to obtain fused information corresponding to a specified target (e.g., a user).

When the server is software, it may be implemented as a plurality of software or software modules (for example, to provide distributed services), or may be implemented as a single software or software module, and is not limited specifically 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 in accordance with the present disclosure is shown. The method for acquiring information comprises the following steps:
in step 201, each information acquisition device in a plurality of information acquisition devices acquires at least one piece of initial information of a specified target.
In the present embodiment, an 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 a wired connection manner or a wireless connection manner. The terminal devices 101, 102, and 103 may be information collecting devices distributed in different geographic spaces. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
The prior art can acquire various types of information through various information acquisition devices. However, the number of types of information acquired by the information acquisition apparatus is limited, and the data format may differ between information acquired by different information acquisition apparatuses. Although the information collected by different information collecting devices can be fused in a bridging mode, a bridging node is required when the information is fused. Therefore, some information which is not directly related cannot be identified through bridging, and partial information cannot be fused easily. Moreover, the bridging mode is not easy to directly understand the information fusion process, and the difficulty of information fusion is increased. Therefore, the prior art is not easy to realize the information fusion collected by a plurality of information collecting devices.
Before information is fused, an execution main body of the application can establish information connection with information acquisition equipment (namely terminal equipment 101, 102 and 103) in various ways to acquire at least one piece of initial information acquired by each information acquisition equipment. Wherein each of the plurality of information acquisition devices acquires at least one piece of initial information of a specified target.
The fusion of the information is performed aiming at a specific specified target. Wherein the specified target may be a specified certain user. For example, a certain user is acquired by a plurality of information acquisition devices to obtain different initial information, and the execution main body of the application can fuse the information acquired by the plurality of information acquisition devices to acquire the fused information corresponding to the user. Similarly, the execution agent may implement fusion of the initial information of each designated user.
After obtaining at least one piece of initial information of the plurality of information acquisition devices, the execution main body may first construct an information relationship diagram 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 detection device, and the security detection device may query information of a plurality of electronic devices carried by a user. Simultaneously, the facial image of the user can be collected. In this way, the facial image of the user and other collected information can be constructed into an information relationship graph. The information relationship graph can characterize the association relationship 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 implementation manners of this embodiment, the constructing an information relationship diagram 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 the construction of the information relationship graph, the execution subject may use the initial information as a node, and connect the initial information with the association relationship through a line. Therefore, the mutual relation among all information is clarified, and the interpretability of the constructed 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 mobile phone number and an Imei code. When the information acquisition equipment acquires initial information of a certain 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 both 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 collected by each of the information collection apparatuses 1 to 5 is shown in fig. 3, wherein ①, ②, ③ · represents initial information, and a connection line between the initial information represents that the two pieces of initial information connected have an association relationship.
In some optional implementation manners of this embodiment, the constructing an information relationship diagram by using the at least one piece of initial information may further include: and responding to the sub-graph existing in the information relation graph, and performing information fusion on the sub-graph through reference data corresponding to the specified target.
As can be seen from the above description, the execution subject may associate some initial information (e.g., the above-mentioned mobile phone number and Imei code) with obvious association. In practice, the information acquisition device can acquire a plurality of pieces of initial information of the same user, which do not have obvious association relationship. For example, the initial information may be a mobile phone number, an Imei code, an identification number, and the like. The mobile phone number and the Imei code have a clear association relationship. And there is no clear association between the mobile phone number and the identity card number. At this time, when the information relationship graph is constructed, a sub graph occurs. The sub-graph may include a part of the initial information in at least one piece of initial information acquired by the corresponding information acquisition device. When the subgraph appears, the correlation relation cannot be established for all the initial information acquired by the information acquisition equipment.
Therefore, the execution main body of the application can inquire the reference data and perform information fusion on the subgraph through the reference data. The reference data may be user information collected by an organization with higher reliability. For example, the reference information may be the user's identification number, cell phone number, fingerprint, gender, age, etc. The execution main body can establish the incidence relation between the initial information acquired by the information acquisition equipment according to the reference data, and further realize the information fusion of the subgraph. For example, in the above-mentioned mobile phone number, Imei code, and identity card number, the mobile phone number and Imei code form a sub-graph, and the identity card number also forms a sub-graph (a sub-graph containing only one piece of initial information). The reference data acquired by the execution main body may be an identity card number, a mobile phone number, a fingerprint, a gender, an age, and the like of the user, and the reference data is related to the user. At this time, the execution main 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 correlation 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 graphs corresponding to the plurality of information acquisition devices to obtain fused information corresponding to the specified target.
As can be seen from the above description, the information collected by different information collecting devices may be different. The above describes a process in which the information acquisition device constructs an information relationship diagram for at least one piece of initial information acquired by the information acquisition device, and information fusion is realized. And then, the execution main body can also fuse the information relation graphs corresponding to all the information acquisition devices to obtain the fusion information of the specified target. Therefore, information fusion of a plurality of information acquisition devices can be realized, and fusion information is finally obtained. Therefore, the information fusion of the initial information acquired by a plurality of different information acquisition devices is realized in a graph fusion mode.
In some optional implementation manners of this embodiment, the fusing the plurality of information relationship graphs corresponding to the plurality of information acquisition devices to obtain fused information corresponding to the designated target may include the following steps:
and the first step, inquiring at least one piece of common initial information among the plurality of information relationship graphs.
In order to establish the association relationship between different information relationship diagrams and realize information fusion, the execution subject may first query the common initial information between the information relationship diagrams. The common initial information may be present in at least two information relationship graphs of a plurality of information relationship graphs. That is, the common initial information is the initial information common to the at least two information relationship maps.
And secondly, fusing the plurality of information relation graphs based on the at least one piece of common initial information to obtain fused information corresponding to the specified target.
After the common initial information is determined, the execution subject can establish the incidence relation among the initial information in the plurality of information relation graphs according to the common initial information, realize the information fusion of the plurality of information relation graphs in a graph fusion mode, and finally obtain the fusion information.
The acquisition of the common initial information and the fusion information on the basis of fig. 4 is shown in fig. 5.
In some optional implementation manners of this embodiment, the fusing the plurality of information relationship graphs based on the at least one piece of common initial information to obtain fused information corresponding to the designated target may include the following steps:
the method comprises the following steps of firstly, taking at least one piece of public initial information as a starting point, and associating initial information in at least two information relation graphs associated with the at least one piece of public initial information to obtain an initial fusion graph corresponding to the at least one piece of public initial information.
There may be a plurality of common initial information. For each piece of common initial information, the execution subject may perform fusion with the common initial information as a starting point. Specifically, the execution subject may use the common initial information as a starting point to fuse the initial information in at least two information relationship graphs corresponding to the common initial information, so as to obtain an initial fusion graph. For example, some common initial information corresponds to two information relationship graphs. The initial information contained in the two information relationship graphs can be: information relationship fig. 1 is: information 1-information 2-information 3-information 4; the information relationship fig. 2 is: information 5-information 6-information 7-information 3. Wherein, the information 3 is common initial information. The executing agent may fuse the information relationship graph with the information 3 starting point to obtain an initial fused graph. The initial fused graph may contain three information chains: a first information chain: [ information 3-information 4 ]; a second information chain: [ information 3-information 2-information 1 ]; a third information chain: [ information 3-information 7-information 6-information 5 ]. Here, "-" may be used to indicate that two pieces of initial information connected have an association relationship.
In practice, different information acquisition devices may acquire the same initial information, and when an initial fusion graph is obtained through common initial information, a case may occur where one initial fusion graph includes a plurality of pieces of the same initial information. At this time, the execution body may retain only one of the repeated initial information. The association of the deleted other duplicate initial information may be recursive. For example, a chain of information 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 "information 6" is: [ 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 associated information relationship maps exist of a plurality of common initial information. At this time, the execution principal may further acquire the confidence of the common initial information. Wherein the confidence level is used for representing the reliability degree 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 common initial information is an identification number and a mobile phone number. At this time, the execution main body may consider that the execution degree of the identification number is higher than that of the mobile phone number. Thereafter, the execution subject may associate from the identification 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.
The common initial information typically does not appear in all information relationship graphs at the same time. That is, the number of the initial fusion maps obtained is usually plural. At this time, the execution subject may further merge (i.e., map merge) the plurality of initial merged maps to obtain a merged map. The initial information in the fusion graph is the fusion information corresponding to the designated target.
In some optional implementation manners of this embodiment, the merging at least one initial fusion graph into a fusion graph and obtaining fusion information corresponding to the designated target according to the fusion graph may include the following steps:
the first step, responding to the existence of at least one fused subgraph in the fused subgraph, and constructing at least one piece of virtual information corresponding to the at least one fused subgraph.
The initial information in the fusion graph may have an association relationship with each other, or there may be initial information that cannot be associated with other initial information to form a complete information chain. That is, there may be a fused subgraph within the fused graph. At the moment, the execution main body builds virtual information to establish the incidence relation of the initial information among the fused subgraphs. The virtual information may be used to establish an association relationship of the initial information between the at least one fused subgraph.
As shown in fig. 5, the fused information in the fused graph has a fused subgraph, such as a fused subgraph formed by the initial information in two dashed circles in the fused graph. At this time, the execution subject may construct virtual information based on the fused subgraph.
And secondly, associating the at least one piece of virtual information with the at least one fusion subgraph to obtain fusion information.
After the virtual information is constructed, the execution main body can establish the incidence relation of the initial information among the multiple fusion subgraphs through the virtual information to obtain the fusion information. That is, the fusion information at this time is an information chain in which all the initial information acquired by the plurality of information acquisition devices are associated with each other.
In some optional implementation manners of this embodiment, the constructing at least one piece of virtual information corresponding to the at least one fused sub-graph may include the following steps:
the first step is to inquire the position information of each initial information in at least one piece of initial information contained in the at least one fused subgraph.
In practice, different information collecting devices are often distributed in different physical spaces, i.e. the information collecting devices have location information. In order to establish the association relationship of the initial information in the fused subgraph, the execution main body may first acquire the position information of each initial information in the fused subgraph.
And secondly, calculating at least one distance value corresponding to the initial information in the at least one fused subgraph according to the position information.
The fusion subgraph comprises a plurality of initial information and corresponds to a plurality of position information. The execution subjects may calculate distance values between the position information two by two.
And thirdly, constructing the 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 equipment usually acquires initial information of a large number of users, the time for acquiring the initial information of a designated target by different information acquisition equipment is short, and correspondingly, the relevance of the initial information of the designated target acquired by different information acquisition equipment is larger. That is, when a distance value smaller than a set distance threshold exists between the fused subgraphs, a plurality of pieces of initial information corresponding to the distance value can be constructed as virtual information.
It should be noted that after the association relationship between the initial information in the fused subgraph is established through the virtual information, the initial information in the fused subgraph corresponding to the virtual information will be replaced by the virtual information. The corresponding association relationship is also transferred from the corresponding plurality of initial information to the virtual information.
As shown in fig. 6, the execution body determines initial information numbered 9, 15, and 17 by calculating a distance value, and may construct virtual information. Wherein the initial information with the number of 9 comes from the information acquisition equipment 3; the initial information numbered 15 comes from the information acquisition device 4; the initial information numbered 17 comes from the information collecting apparatus 5. It is explained that the actual positions of the information collection device 3, the information collection device 4, and the information collection device 5 satisfy the distance threshold. After that, the virtual information X is constructed from the initial information numbered 9, 15, and 17. Other initial information having an association relationship with the initial information numbered 9, 15 and 17 has an association relationship 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 by each to the server 105. The server 105 constructs corresponding information relation graphs of the initial information by taking the information acquisition equipment as a unit. Finally, the server 105 fuses the information relationship graph to obtain fused information.
The method provided by the above embodiment of the present disclosure first obtains at least one piece of initial information acquired by a plurality of information acquisition devices; then, an information relation graph is constructed through at least one piece of initial information, and information fusion of the initial information acquired by the single information acquisition equipment is realized; and finally, fusing a plurality of information relation graphs corresponding to a plurality of information acquisition devices to obtain fused information corresponding to the specified target. The method and the device realize 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 illustrated. The process 800 of the method for obtaining information includes the following steps:
in step 801, each information acquisition device of a plurality of information acquisition devices acquires 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 is not described in detail here.
The content of step 802 is the same as that of step 202, and is not described in detail here.
The content of step 803 is the same as that of step 203, and is not described in detail here.
When the execution main body receives the information query request corresponding to the specified target, the execution main 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. The information quantity and the information accuracy of the initial information of the specified target are improved.
