Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flowchart of a pushing method of spatial knowledge information streams provided by an embodiment of the present invention, which may be performed by any device with data processing capability. As shown in fig. 1, the method comprises the steps of:
step S110, a space knowledge base of the physical space is constructed.
The spatial knowledge base is based on spatial semantics and spatial relationships and is used for recording knowledge information in a physical space, and the knowledge information in the physical space may include knowledge information associated with entities or places in the physical space, including, for example, facility information, service information, activity information, equipment information, resource information (people, equipment, and energy), and the like.
By way of example, a physical space is understood to be a building with a business function, a business domain, such as a mall, a hospital, a museum, an office building, a school, a gymnasium, a park, etc.; taking a gymnasium as an example, a place in a physical space can be understood as a physical place with space and business functions in a mall, such as a basketball court, a volleyball court, a swimming pool, a gymnasium and the like; an entity in the physical space is understood to be any item in the gym, including a security exit sign, lights, charging dock, cup, ventilator, etc. The information (including attribute information, business domain, function, activity content, etc.) related to these physical places and articles is knowledge information in the physical space.
In specific implementation, the spatial knowledge information contained in the spatial knowledge base can be acquired in the following manner: firstly, the AI is obtained by AI identification and learning during 3D scanning reconstruction; secondly, the user marks or inputs the information through the system; thirdly, the user marks or inputs the information in an AR mode; and fourthly, the method is obtained through IoT equipment entry and AI learning. In practical application, the spatial knowledge base is continuously expanded and updated according to actual needs.
Step S120, receiving the real-time space context of any user entity in the physical space; the real-time spatial context contains the user entity name, timestamp information, and spatial coordinates of the user entity.
Real-time spatial context generally refers to information characterizing the real-time location and real-time environment of a user entity. The user entity name is a unique identifier of the user entity, and the timestamp information may be timestamp information of each event after the user entity enters the physical space. The spatial coordinates of the user entity are coordinates in a spatial relative coordinate system of a physical space, and the position has different coordinate expressions according to the coordinate system, for example, the coordinates of the center of a certain conference hall in a longitude and latitude-based coordinate system are (12947022.9340131414837329.479655989, 19.68 z), and the coordinates in the spatial relative coordinate system are (0, 0, 0).
In an alternative mode, after the user is detected to enter the physical space, the spatial position information of the user is recorded in real time, and the spatial coordinates of the user can be directly read from the background database.
Step S130, inquiring the spatial knowledge base according to the real-time spatial context to obtain the spatial knowledge information to be pushed.
The real-time spatial context of the user entity is inquired and matched with knowledge in the spatial knowledge base, so that spatial knowledge information around the user entity is collected, the spatial knowledge information to be pushed is determined, the user can receive and know the knowledge information of the space where the user is located, the user can conveniently know and use the knowledge and the information in the physical space where the user is located, and the user can conveniently use services and resources in the physical space.
Step S140, pushing the spatial knowledge information to be pushed to the user entity in the form of information stream.
Finally, the queried spatial knowledge information to be pushed is formed into an information stream to be pushed to the user entity, for example, to a mobile device of the user entity, or to a multimedia device near a real-time location of the user entity.
In an alternative mode, a real-time channel is formed between a user and a space operating system through a long TCP link to transmit a space knowledge information stream.
According to the pushing method of the spatial knowledge information flow provided by the embodiment, a spatial knowledge base of a physical space is constructed; receiving a real-time spatial context of any user entity in a physical space; the real-time spatial context comprises a user entity name, timestamp information and spatial coordinates of the user entity; inquiring a spatial knowledge base according to the real-time spatial context to obtain spatial knowledge information to be pushed; pushing spatial knowledge information to be pushed to a user entity in an information flow mode; the method can move along with the position of the user entity according to the real-time space context of the user in the physical space and the knowledge information of the physical space where the user is located, acquire, calculate and aggregate the related spatial knowledge information around the position of the user entity, and further push the content of the user, so that the effect of pushing along with walking can be realized, the method can help the user to efficiently and immediately obtain effective information in the physical space, the value of the user based on the pushed information is improved, the interference of a large amount of irrelevant information is avoided, and the method is favorable for improving the pushing conversion rate and the pushing effect.
Fig. 2 shows a flowchart of a pushing method of spatial knowledge information stream according to another embodiment of the present invention, which may be executed by any device with data processing capability, as shown in fig. 2, and the method includes the following steps:
step S210, a space knowledge base of the physical space is constructed.
In an alternative approach, a knowledge base of the physical space is constructed using knowledge-graph techniques.
Step S220, receiving the real-time space context of any user entity in the physical space; the real-time spatial context contains the user entity name, timestamp information, and spatial coordinates of the user entity.
In particular, whether the user entity enters the physical space may be detected by detecting a specific event, which may be, for example, a card swipe event, a face swipe event, a registration event, and so on. Optionally, the specific event also carries a unique identifier of the user entity, and it may be determined which user entity enters the physical space according to the user entity identifier carried in the received specific event, where the user entity identifier is allocated when the user registers or when the specific event is triggered for the first time, which is not limited in the present invention.
Step S230, querying the spatial knowledge base according to the real-time spatial context to obtain spatial knowledge information to be pushed.
And inquiring and matching according to the real-time space context of the user entity and the knowledge in the space knowledge base so as to collect the space knowledge information around the user entity and determine the space knowledge information to be pushed.
The spatial knowledge base is queried according to the entity spatial context, so as to obtain various matching algorithms used for obtaining the spatial knowledge information to be pushed, for example: a matching algorithm based on a memory and a collaborative filtering matching algorithm based on a model; the matching algorithm based on the memory includes a matching algorithm based on the content and a matching algorithm based on the proximity, and the matching algorithm based on the proximity includes a filtering algorithm based on the user cooperation and a system filtering algorithm based on the Item, or the matching processing can be performed by fusing a plurality of algorithms, which is not limited in the present invention.
And step S240, filtering the spatial knowledge information to be pushed.
The real-time spatial context also comprises parameters for screening spatial knowledge information, the parameters can represent the interest of the user entity, and the spatial knowledge information to be pushed, which is obtained by query, is filtered based on the parameters, so that the knowledge information pushed to the user entity can better meet the requirements of the user.
Specifically, the real-time spatial context further includes a subscription parameter, where the subscription parameter represents a range or a channel of knowledge information subscribed by the user, and after the spatial knowledge information to be pushed is obtained, it is determined whether the spatial knowledge information to be pushed is matched with the subscription parameter, if so, the spatial knowledge information to be pushed is retained, otherwise, the spatial knowledge information to be pushed is filtered. For example, if the user subscribes to a food channel, spatial knowledge information related to clothing in the spatial knowledge information to be pushed may be filtered, and spatial knowledge information related to food in the spatial knowledge information to be pushed may be retained. According to the method, the subscription parameters, the real-time position and the knowledge information of the place where the user is located are integrated to determine the push content for the user, so that the user can know valuable knowledge information in the current space, and the reasonability and the value of the push content can be improved.
Specifically, the real-time spatial context further includes an application identifier, where the application identifier is used to determine an application used by the user entity in real time, and on this basis, spatial knowledge information currently interested by the user entity and spatial knowledge information not interested by the user entity can be inferred, so that the spatial knowledge information to be pushed can be filtered according to the application identifier. For example, if the user entity is currently using a map application, the knowledge information irrelevant to the location information in the spatial knowledge information to be pushed may be filtered, and the spatial knowledge information relevant to the location information in the spatial knowledge information to be pushed may be retained.
In an alternative, the real-time spatial context further comprises: and the wireless equipment information scanned by the equipment corresponding to the user entity. The role of the wireless device information scanned by the device corresponding to the user entity is as follows: calculating the spatial position of the user entity according to the wireless device information scanned by the device corresponding to the user entity, for example, more accurately determining the position information of the user entity according to the position of the wireless device nearby scanned by the user entity device; and/or judging the magnetic field environment condition of the user entity; and/or generating new spatial knowledge information.
In an alternative manner, the future spatial trajectory information of the user entity is obtained by prediction according to the historical spatial trajectory information of the user entity, and then in step S230, the spatial knowledge base is queried to obtain the spatial knowledge information to be pushed, further by combining the future spatial trajectory information of the user entity and the real-time spatial context of the user entity, that is, the future possible movement trajectory of the user is predicted according to the trajectory that the user has traveled, and the pushed content matched with the future possible trajectory of the user is queried. The method can enlarge the range of the push content and provide valuable push content as much as possible for the user.
And step S250, pushing the filtered and reserved space knowledge information to be pushed to display equipment within a preset range of the real-time space position of the user entity in an information flow mode.
After the spatial knowledge information to be pushed is obtained through matching, the spatial knowledge information to be pushed is pushed to display equipment in a certain range near the real-time position of the user, wherein the display equipment comprises a mobile terminal used by the user, a display screen near the position where the user is located and the like. Of course, besides active pushing, the display device may also actively pull the spatial knowledge information to be pushed, which is not limited in the present invention.
According to the pushing method of the spatial knowledge information stream provided by the embodiment, according to the real-time spatial context of the user in the physical space and the knowledge information of the physical space where the user is located, the method can move along with the position of the user entity, and acquire, calculate and aggregate the spatial knowledge information related to the periphery of the position of the user entity, so as to push the content of the user, so that the effect of pushing along with walking can be realized, the user can be helped to efficiently and immediately acquire effective information in the physical space, the value generated for the user based on the pushed information is improved, the interference of a large amount of irrelevant information is avoided, and the pushing conversion rate and the pushing effect are improved.
Fig. 3 shows a functional block diagram of a pushing system for spatial knowledge information stream according to another embodiment of the present invention, where the system is located at a server side, and as shown in fig. 3, the system includes: the system comprises a space track recording system, an information flow calculating and pushing system and a space knowledge base system, wherein the systems can be in a cluster form.
The spatial track recording system acquires position information by adopting a positioning technology, continuously records the position information by adopting a data technology, and reads the spatial coordinates of a user from the spatial track recording system when the position information is accurate to human recording.
The space knowledge base system is provided with a three-dimensional reconstruction function and a perception network for finishing real-time updating, and is also provided with a user interface for inputting and updating.
The information flow calculating and pushing system comprises a calculating engine and a pushing system, wherein the calculating engine is used for converging the spatial knowledge around the user, and the pushing system is used for pushing the calculated spatial knowledge information flow to a display screen around the user or handheld equipment of a user entity.

As shown in the figure, when the user entity walks to the spatial location S0, the information flow calculation and pushing system pushes the spatial real-time information flow T0 to the user entity, and when the user entity walks to the spatial location S1, the information flow calculation and pushing system pushes the spatial information flow T1 to the user entity, which may be pushed to a display screen near the user or a mobile terminal of the user.
