Description

Offline store state sharing service provision system {SYSTEM FOR PROVIDING OFFLINE STORE INFORMATION SHARING SERVICE}

The present invention relates to a system for providing an offline store state sharing service, and provides a platform for sharing information that satisfies immediateness and presentness by checking whether or not to open in real time or periodically based on business hours.

Location-Based Service is being analyzed as a new business resource including automatic local advertisement, with location-based search and advertisement taking the largest proportion. The LBS business based on location information collected from smartphones has been developed as a service that analyzes the characteristics of locations from various location information APIs and provides them as individual applications, and is used for indoor positioning, navigation of cars and ships, and gradually expands its scope. Therefore, it is being used for advertisements, location-based marketing, location-based AR games, and services using drones. In terms of public service, the technology of inquiring location information for rescue work in situations where rescue is necessary as a social safety net is also gradually developing. Although cases of using individual location information are evolving, it is still necessary to develop a technology that combines various location information already presented and performs a normalization process to reprocess it into more accurate information.

At this time, research and development of a platform for predicting store business hours or sharing food truck information was conducted. In this regard, Korean Patent Registration No. 10-2084920 (announced on March 5, 2020) and Korea In Public Patent No. 2019-0105186 (published on September 16, 2019), data on the business status of neighboring living facilities corresponding to power consumption data for collecting power consumption data of neighborhood living facilities and for supervised learning. Input the power usage data of the neighborhood living facilities collected by the power usage information collection unit and the operation status data of the neighborhood living facilities entered by the actual measurement data input unit for more than a preset period to perform machine learning. The configuration to create a model for predicting business hours of neighborhood living facilities using electricity consumption data and business availability data as parameters, and the location information of food trucks, representative photos, business hours, and through the social network service of the food truck store owner. Each of the configurations for extracting information on the current business status and extracting information on food prices, food types, and types of ingredients used are disclosed as attributes of the restaurant industry.

However, making predictions using big data is literally a prediction or prediction, and cannot be a means of confirming whether it is currently operating or not. In addition, even if food truck information is extracted through SNS, if there is no SNS feed for the food truck, the food truck does not exist online. Customers search to find the information they need at the present time, but ironically, the searched data is data created at a time in the past, but it is less reliable to judge by looking at past data to determine whether it is currently operating or not. . Therefore, the customer must call to check whether it is open or not, and even in the case of non-store stores, there is no phone number, so the instantaneous discovery of the location as the customer passes by is required, and there is a way to notify the customer even the business hours. none. Accordingly, there is a need for research and development of a method to check the business status in real time and share it.

In one embodiment of the present invention, the store's business hours, product information, and vacation information are uploaded and stored from at least one affiliated store terminal, but the business status independent from the business hours is real-time or periodic communication with at least one affiliated store terminal. Through this, it checks whether it is open or not, and whether to keep the open state or change the open state to the closed state. In the case of a non-store store without a store, if the start business button on the affiliated store terminal is selected, check it as open and share it. In the case of a non-store store that changes its location, the real-time location of the affiliated store terminal is continuously checked until the business end button is pressed so that the customer can search based on location or search word, even if the store is moving. It is possible to provide a method of providing offline store status sharing services that enable customers to search and use not only stores but also stores that are non-stores. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention searches for at least one store based on a location or a search word, and includes business hours, open status, and vacation information of at least one store. When the store is registered by uploading the user terminal that outputs status information, the store's location, business name, store information including business hours and vacation information, and a response signal to a real-time or periodic call signal is in wakeup state By transmitting, at least one affiliated store terminal that uploads open status and a storage unit that registers and stores store information from at least one affiliated store terminal, and transmits a real-time or periodic call signal to at least one affiliated store terminal, and responds to the call signal. In the case of receiving a response signal, an upload unit that detects the wake-up of at least one affiliated store terminal and uploads whether it is open, and a display unit that displays at least one affiliated store terminal that wakes up based on a time searched by the user terminal as open. It includes a server that provides a state sharing service.

According to any one of the above-described problem solving means of the present invention, the store's business hours, product information, and vacation information are uploaded and stored from at least one affiliated store terminal, but the business status is determined by at least one affiliated store terminal and It checks whether it is open through real-time or periodic communication of, and checks whether to keep the open state or change the open state to the closed state.In the case of a non-store store without a store, when the start button of the affiliated store terminal is selected, In the case of a non-store store that checks open, shares, and changes its location, the real-time location of the affiliate store's terminal is continuously checked until the business end button is pressed so that customers can search based on location or search word, even if it is a moving store. Through this, customers can search and use not only stores with stores but also stores without stores.

2 is a block diagram illustrating a state sharing service providing server included in the system of FIG. 1, and FIGS. 3 and 4 illustrate an embodiment in which an offline store state sharing service is implemented according to an embodiment of the present invention. It is a drawing for explanation.

Referring to FIG. 2, the state sharing service providing server 300 includes a storage unit 310, an upload unit 320, a display unit 330, a non-store management unit 340, a location sharing unit 350, and a mobile sharing unit ( 360), a leadership unit 370, a review sharing unit 380, and may include a change unit 390.

The state sharing service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with the at least one user terminal 100 and at least one affiliated store terminal 400 share the offline store state When transmitting a service application, program, app page, web page, etc., at least one user terminal 100 and at least one affiliated store terminal 400 may provide offline store state sharing service applications, programs, app pages, web pages, etc. Can be installed or opened. In addition, a service program may be driven in at least one user terminal 100 and at least one affiliated store terminal 400 by using a script executed in a web browser. Here, the web browser is a program that allows you to use the Web (WWW: World Wide Web) service, which means a program that receives and displays hypertext described in HTML (Hyper Text Mark-up Language). For example, Netscape , Explorer, Chrome, etc. In addition, the application refers to an application program on the terminal, and includes, for example, an app running on a mobile terminal (smartphone).

Referring to FIG. 2, the storage unit 310 may register and store store information from at least one affiliated store terminal 400. The at least one affiliated store terminal 400 may register a store by uploading store information including store location, business name, business hours, and vacation information. In this case, the business hours may be set based on weekdays, weekends, or the like, or may be set for each day of the week. For example, it may be set for each day of the week from 8 am to 12 pm Monday to Friday, 9 am to 2 am on Saturday, 9 am to 1 am on Sunday, and so on. In addition, the affiliated store terminal 400 may be a terminal that sets the type, menu, and price of products to be sold by designating a product category tag.

The upload unit 320 transmits a real-time or periodic call signal to at least one affiliated store terminal 400, and when receiving a response signal corresponding to the call signal, detects the wakeup of at least one affiliated store terminal 400, and You can upload whether it is open or not. The at least one affiliated store terminal 400 transmits a response signal to a real-time or periodic call signal when it is in a wakeup state, and uploads whether it is open or not. The reason for sending the call signal was indicated by business hours, but it was not actually open because part-time workers did not go to work, or the business was temporarily closed for several weeks due to the recent coronavirus (COVID-19), or extended in case of holidays. This is because there may be cases or cases of opening earlier and vice versa.

In this case, the affiliated store terminal 400 may be a POS terminal in the case of a store with a store, and most of the POS terminals are turned on after a part-time job student or store owner goes to work. When the POS terminal is not turned on, it is data that can confirm in real time that the door is almost closed. In an embodiment of the present invention, after sending a signal to the POS terminal, it can be confirmed that the opening is not possible if there is no response thereto. It may be a PING signal, but is not limited thereto. In addition, SaaS (Software as a Servcie) may be used so that the upload unit 320 and the affiliated store terminal 400 can communicate with each other without purchasing a separate application or program.

SaaS is easily accessible from anywhere on the Internet, and can be accessed from anywhere with a web browser. At this time, it is also possible to add more BaaS (Backend as a Service) according to the requirements of the affiliated store. Of course, in the case of affiliate stores that do not have an infrastructure or platform itself, various infrastructure resources such as server resources, IP, network, storage, and power required for server operation can be flexibly and quickly provided through IaaS (Infrastructure as a Service). IaaS can easily add or remove resources and provide an operating system, so a familiar environment can be given. In addition, a service can be provided through PaaS (Platform as a Service), which provides a stable environment and APIs for developing application programs that use the environment. PaaS can easily build and deploy source code, and it is easy to scale out according to usage. BaaS is a mobile application-specific service, and it can provide server-side applications such as merchant management, push, and file processing that are difficult to handle in mobile applications. PaaS platform can be used, and the provided backend module can be configured to be used immediately through REST API or library CALL.

In addition, an embodiment of the present invention is at least one camera or affiliated store interlocked with the affiliated store terminal 400 in consideration of the probability that the affiliated store terminal 400 may function incorrectly (Malfunction), or a delay or error of a signal may occur. It may be configured to check whether a person exists in a store or a non-store store exists in a corresponding location in real time using a camera vision sensor of a camera that illuminates the location of the terminal 400. The camera sensor is capable of acquiring a variety of intelligent information such as tracking a person, identifying the number of people, and performing a person's actions. Using a camera vision sensor, it is possible to analyze the occupancy and behavior of a person, or detect a moving person. At this time, since a person may be in a static state for a long time, it can be set to identify a person without movement as a person, and non-human objects can stop or remove tracking. Basically, people counting is performed, and when the number of people reaches 0, it can be estimated as the end time. Background modeling and foreground extraction continuously update the background and search for multiple foreground objects. Because of the movement of people and objects, motion is data suitable for human detection and tracking. It is also possible to increase the tracking performance of an object by using a motion history image (MHI) as motion information.

The display unit 330 may display at least one affiliated store terminal 400 that wakes up based on a time searched by the user terminal 100 as open. Accordingly, the user terminal 100 may search for at least one store based on a location or a search word, and output status information including business hours, open status, and vacation information of the at least one store. Of course, it is possible to select and show only regular stores near the house, but is not limited thereto.

In the case of a non-store store without a store, the non-store management unit 340 may set to open and upload when a business start button is selected from at least one affiliated store terminal 400. The location of non-stores is not constant. Of course, there are cases where you pay a tax and do business in a fixed place, but there are cases where it is not. In the former case, a business location and business hours may be set, and in the latter case, a location of a time when a business start button is pressed on the affiliated store terminal 400 may be set as the business location. In the latter case, the business location may be updated by tracking the location of the affiliated store terminal 400 periodically, for example, in an hour unit or a moving time unit. And, even if there are business hours, most of the business ends when the ingredients run out, so you can press the business end button separately from business hours so that there are no customers who leave the business hours and make a fuss about it. .

The location sharing unit 350, in the case of a non-store store without a store, when selecting a business start button from at least one affiliated store terminal 400, the GPS of at least one affiliated store terminal 400 at the time when the business start button is selected. By setting the location as the location of a non-store shop, you can upload it as open. However, GPS accuracy is limited due to delay time errors of signals received from satellites, effects of the ionosphere, satellite clock errors, and errors due to multiple paths. The location accuracy of commercial GPS is known to be about 10 [m] horizontally and about 20 [m] vertically. In the case of non-store stores, the location accuracy must be provided enough for customers to see and visit the map. At this time, the easiest approach for improving location accuracy is RTK (Real Time Kinematic)-GPS, A-GPS (Assisted GPS), DGPS (Differential GPS), CDGPS (Carrior phase DGPS), which include correction algorithms for various errors. Etc. can be used.

However, these methods can obtain accurate location information, but require a separate communication link, additional infrastructure, and high cost. Accordingly, a method of correcting the location information of the low specification GPS by performing matching between the location information of the low specification GPS can be used. If a vehicle such as a food truck is always driving on the road, iteratively targets the location information of the center line included in the map information and the location information of the low-spec GPS acquired for a certain time from the present to the past while the vehicle is driving. The rotation matrix and translation vector of the location information of the low-spec GPS obtained based on the location information of the center line of the map are calculated through the Closest Point (ICP) algorithm, and by using this, the low-spec GPS It is also possible to use a method of improving the location accuracy of the low-spec GPS by performing additional correction by correcting the location information to approximate the center line of the map and projecting the additionally corrected low-spec GPS location information to the center line of the map.

Usually, the ICP algorithm is an algorithm that calculates a rotation matrix and a translation vector that minimizes the distance difference between two point groups. 2D or 3D point cloud data of the environment acquired from the previous frame and the current frame from sensors (images, LIDAR, RADAR, etc.) Although it is used in the field of creating a map or estimating the location by matching each other, the method according to an embodiment of the present invention newly expands the field of the iterative nearest point algorithm, and the center line of map information is not matched between scanned sensor data. Since it can be used for matching between location information and low-spec GPS location information to improve the location accuracy of low-spec GPS, it does not require an additional sensor, and a relatively small amount of calculation is required due to the matching between location information and location information. Even if your mobile phone has a low specification, you can use it without limitation of computing and networking resources.

The mobile sharing unit 360, when a non-store store without a store is a mobile store, when a business start button is selected from at least one affiliated store terminal 400, at least one affiliated store terminal 400 at a time when the business start button is selected. ), the location of the non-store store is set as the location of the non-store store, uploaded, and the GPS location of at least one affiliated store terminal 400 is tracked for each preset period, and the location can be shared until the business end button is selected.

The leadership unit 370 selects any one of the menu category tags from at least one affiliated store terminal 400 to designate the type of product to be sold, and when the user terminal 100 searches for a menu category tag, It may be overlaid on the location of at least one affiliated store terminal 400. In this case, the menu category tag may not be a fixed classifier but a flexible classifier.

Analysis of information resources is required for data purification and classification, but the products sold by each franchisee according to the different terms used in various types of products and different human resources and material resources. In many cases, you cannot express your own information with a preset tag. At this time, if the tag (optional) does not exist, most platforms create other boxes and write information that can express the product on others.In order to tag the described data, one embodiment of the present invention In the following, words and sentences included in other boxes are expressed in a vector form, and then words and sentences of other boxes expressed in a vector form are clustered. At this time, clustering is a representative unsupervised learning method that is widely applied in studies in the fields of text mining and information retrieval, and according to the clustering method, hierarchical clustering, partitional clustering, and spectral structure clustering Clustering).

The most commonly used clustering algorithms are the agglomerative hierarchical clustering algorithm and the K-means algorithm, and the K-means algorithm is evaluated as an efficient clustering algorithm although its performance is lower than that of bottom-up hierarchical clustering. Accordingly, in an embodiment of the present invention, the K-means algorithm may be applied as a clustering algorithm by focusing more on efficiency than on clustering performance. Of course, the bottom-up hierarchical clustering algorithm is not excluded. In this case, the K-means algorithm is performed under the premise that K center points in the vector space can be expressed as K clusters, and in general, clusters are formed by calculating the cosine similarity of each vector. The K-means algorithm can further use various extension algorithms such as bisecting, antipole, and multipole, depending on the cluster creation method.

The above-described process will be described in detail as follows.

First, a morpheme analysis and stopword removal process of words and sentences described in other boxes may be performed. In order to perform K-means with words and sentences written in other boxes, data written in other boxes should be converted into a form suitable for performing clustering. To this end, a numerical process is performed to convert words and sentences into vectors. Morphological analysis of words and sentences is performed for numerical work, and as a result, each morpheme forms the dimension of a vector. Depending on whether the corresponding morpheme is included, each vector element has a value of 1 or 0, and a morpheme analyzer can be used in this process.

The second is to create a tag pool. Distance measurements and comparable criteria between other boxes in which words and sentences are written are achieved through vector multiplication. To this end, it is necessary to define a standard vector that contains information on all morphemes, and the tag pool extracted from all other boxes can be used with this standard vector. The tag pool refers to a pool that contains all tags extracted from words and sentences included in all other boxes without overlapping.

The third is the process of creating a tag hierarchy, which is created based on the previously created tag pool. A vector for generating a tag hierarchy may be assigned a vector value according to how many times there are arbitrary tags included in the same tag pool while comparing elements of the tag pool with each other. For example, a vector value is assigned according to the degree to which two arbitrary tags are simultaneously input from a word and sentence entered by a plurality of franchisees in one other box. Each of the tag vectors calculated according to this method is converted into a unit vector and then clustered through K-means, and vectors having high similarity are grouped together through cluster analysis, and thus can be classified into several tag groups. And again, it is possible to create a tag hierarchy for the entire tag set by repeatedly applying the above clustering operation to each group.

Finally, the tag vector needs to be calculated, and finally, through the process of creating the tag vector, all preparations for performing the clustering algorithm are completed. Through this process, a criterion for inferring how similar information each other box has to each other is established. In addition, in order to reflect the tag hierarchy in the tag vector, a value calculated based on the hierarchy structure can be used, and the vector value assigned at this time can use, for example, Leacock-Chodorow Measure, but is not limited thereto. . Since the Leacock-Chodorow Measure expresses vocabulary similarity with values ranging from 0 to infinity, it can be applied to update the weight of the tag vector.

When all preparations for clustering are completed in this way, a new tag can be derived by tying each other box. At this time, to determine the first clustering K value, when applying K-means clustering, the number of groups as a result of clustering (K) has an important influence on the clustering performance. In most cases, K is set as a static variable and the clustering results are derived according to the number, but it is very difficult to determine a constant K value when considering the characteristics of having tags in different directions due to the direction and specificity of different products. to be.

Accordingly, in the method according to an embodiment of the present invention, it is possible to set different K values according to different tags according to words and sentences included in other boxes. K-means regenerate clusters repeatedly until an optimal cluster is generated. That is, once a cluster is created by K-means, the centroid value is recalculated for all clustered groups, and vector multiplication is performed on K clusters in order for all tag pools. After that, the tag pool is allocated again to the group with the largest vector product as a result of the execution, and vector product and allocation process is performed until the last tag pool. Accordingly, when a new clustering result is calculated, the process of obtaining the center value is repeatedly performed to achieve an optimal clustering state. At this time, the end point is when no change occurs when the newly formed results are compared with the previous clustering results.

The user terminal 100 is a plurality of user terminals 100 corresponding to different subjects, and the review sharing unit 380 is a rating and review for at least one affiliate store and product received from the plurality of user terminals 100 May be mapped with at least one affiliated store terminal 400, stored, and displayed on a map. At this time, the evaluation criteria used to evaluate each product did not reflect the opinions of different consumers for each product, and the characteristics and themes of the product were extracted through online reviews reflecting consumer opinions and used as evaluation criteria. There is a limitation in that evaluation criteria with a low correlation to and from being extracted or inappropriate words are not refined. Accordingly, the review sharing unit 380 extracts an evaluation criterion candidate group from the review using a latent Dirichlet Allocation (LDA) technique and uses a k-Nearest Neighbor Approach (k-NN) You can use a model to refine it.

The above-described model consists of a preparation step and an extraction step. In the preparatory stage, a word embedding model and a k-NN classifier are created to refine the evaluation criteria candidate group. In the extraction step, the candidate group for evaluation criteria is refined using the k-NN classifier and the mention ratio, and the final result is derived. For performance evaluation, the noun frequency extraction model, the LDA frequency extraction model, and the evaluation criteria provided by the actual product evaluation site can be selected as three comparison models, and the results can be tested by conducting a questionnaire and scoring for comparison with the three models. have. Accordingly, it can be used to derive the dimensions for each product group reflecting the characteristics of a product or food, that is, reflecting the characteristics of the review, rather than a 5 star rating by grouping the ratings. You can contribute.
