Abstract

An intelligent home network service method based on ontology is provided to prevent collision between services and present multimedia service which is provided to a confirmed user through a user interface. First multimedia service information is presented as a user selects one among first location information, first tool information and first service information. According to modifying request of a user about the first multimedia service information, second multimedia service information is generated by modifying one or more information among information included in the first multimedia service information. A priority table(310) in which each priority of location information, tool information and service information included in the multimedia service information is defined and is referred to establish the priority of the second multimedia service information.

Description

Intelligent Home Network Service Method Using Ontology {Intelligent Home Network Service Method using Ontology}

The present invention relates to a home network service method, and more particularly, to a method for providing an intelligent home network service based on ontology.

Home network technology, a leader in digital convergence, has recently emerged as a cutting-edge item in the telecommunications and electronics industries. The home network is a key component of the digital home, the future home environment where information is connected to the home network and service is provided regardless of the device, time, or place.

However, there are only a few realistic models for providing knowledge services using the home network technology as described above. First, CoBrA (Context Broker Architecture) has been developed as a prior study for efficiently managing and sharing various knowledge or information and making context inference. The CoBrA was developed for a broker agent that manages a context sharing model for all computing entities existing in the intelligent space. In addition, Standard Ontology for Uniquitous and Pervasive Applications (SOUPA) has been developed with the aim of a common ontology supporting ubiquitous computing environments.

Many problems arise when applying these existing models to the actual home network service. First of all, the solution of a collision between multiple users for a single device is insufficient, which may cause a service failure. In the case of providing a multi-service provided by the device information, location information, and service information, the same risk exists in the event of a collision between services.

In addition, since there is no practical model to represent the actual device, it does not provide the scalability of the home network service system for the increasingly diverse digital home appliances, and there is no model for configuring the dynamic service according to the user's request. .

An object of the present invention is to provide an ontology-based intelligent home network service method for preventing conflicts between services when providing multiple services.

Another object of the present invention is to provide an ontology-based intelligent home network service method for presenting multiple services available to a user through a user interface.

The object of the present invention is to provide an intelligent home network service using ontology-based location information, device information, or service information having mutual relations, wherein the first location information, the first device information, and the first device information are selected by a user. A first step of obtaining and presenting first multi-service information including at least one of 1 service information; A second step of generating second multiple service information by modifying at least one of information included in the first multiple service information according to a modification request of the user for the first multiple service information; And a third step of setting the priority of the second multiple service information by referring to a priority table in which the priority of each of the location information, the device information, or the service information included in the multi-service information is defined. Is achieved by intelligent home network service method.

The ontology-based intelligent home network service method according to the present invention has the effect of providing multiple services composed of a combination of at least one ontology class without mutual collision.

In addition, the present invention has an advantage that it is possible to efficiently provide an ontology-based home network service by providing only multiple services that can be provided to the identified user.

The terms or words used in this specification and claims are not to be construed as being limited to their ordinary or dictionary meanings, and the inventors may appropriately define the concept of terms in order to best describe their invention. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an embodiment of a home network service model according to the present invention. Referring to FIG. 1, an embodiment of a home network service model according to the present invention may include at least one ontology class of at least one person information, entity information, location information, and service information. Ontology Class (110) is configured to include, the ontology class (110) enables the provision of intelligent home network services by interworking with each other.

Here, the user information ontology class is an ontology for storing information related to the user, and includes basic information about the user, health information of the user, membership information on the group to which the user belongs, and user's It may have ontology subclasses 120 such as interest.

In addition, the device information ontology class is an ontology capable of storing and managing information on various devices for providing a home network service, and includes sensor information for collecting information, basic information about a device, and a device. Ontology subclasses 120, such as attribute information (Actuator) for the attribute of may have.

In addition, the location information ontology class is an ontology for managing a home network space, and has ontology subclasses 120 such as home location information for home locations and office location information for office locations. Can be.

In addition, the service information ontology class is an ontology for configuring and managing the contents of a home network service. The service information ontology class includes session information regarding session use, task information about a task (service), subtask information (Subtask), Ontology subclasses 120 such as device operation information (Operation) related to the device operation service may be provided.

As described above, the ontology classes 110 have ontology subclasses 120, and each subclass 120 is composed of various properties. A property refers to a relationship between objects or data values of an object, and is composed of two types: an object property referring to an object of a class (ObjectProperty) and a data type property (DataTypeProperty) having a specific data value.

The ontology model for providing a home network service according to the present invention provides an intelligent home network service by clearly defining a relationship between a device, an object, such as a location and a service, necessary on the home network using the above components. . In particular, the object property includes information about which class of object the object property refers to, and through the object property, the relationship between each object in the ontology model for providing a home network service according to the present invention can be clearly defined. Can be.

For example, if you look at the user information ontology class, you can prevent the leakage of personal information by including 'privacyLevel', an object property for determining whether a user's profile is disclosed in the ontology that stores information related to personal information. In addition, it is possible to facilitate service management for multiple users by defining a membership information ontology for each group to which each individual belongs as a subclass of the user information ontology class.

In addition, when looking at the device information ontology class, by defining all the sensor information ontology subclasses of sensor-related ontology in the same format, it provides the scalability to easily configure the home network service by easily adding the necessary sensors in the future, Sensor information can be utilized in various devices by including 'hasSensor', an object property that can refer to the sensor information ontology subclass, in the ontology subclass. Here, the 'hasSensor' is an object property for storing information about a sensor used for collecting information such as a state and operation of a device.

In addition, referring to the location information ontology class, the location information ontology class includes information about various sensors and devices, including names of the home spaces and sensors located in the space, to provide an optimal home network service based on location information. I can support them. By linking with devices located in each space, it is possible to efficiently provide services optimized for users.

In addition, when looking at the service information ontology class, the service information ontology class provides extensibility to provide various services by clearly defining service units such as sessions, tasks, and subtasks. On the other hand, by including the user information in the session information ontology subclass to refer to the 'priority' of the user information ontology class, it is possible to prevent a conflict between users in providing a service. Here, the 'priority' is an object property for storing information about priority between users.

2 is a block diagram showing an embodiment of a home network service system according to the present invention. 2, an embodiment of a home network service system according to the present invention is largely composed of a user interface 210 and a home network server 220.

The user interface 210 is for input / output of multiple services to be provided to a user, displays multiple services that can be provided to the user, receives service request information according to a user's selection, and transmits the received service request information to the home network server 220.

The user interface 210 for this purpose includes a communication unit for transmitting and receiving information with the home network server 220, a converter for data conversion when transmitting and receiving information with the home network server 220, and information received from the home network server 220. And a display unit for displaying.

The home network server 220 receives and processes the request information of the user from the user interface 210, and transmits the processed information to the user interface 210 to be displayed through the user interface 210.

The home network server 220 for this purpose includes a communication unit for transmitting and receiving information with the user interface 210, a conversion unit for data conversion when transmitting and receiving information with the user interface 210, and an ontology DB for storing and managing multiple service information. do. It also includes a control unit for controlling the home network server 220 including them.

Here, the multi-service means a service based on the interrelationship between at least one user information ontology class, device information ontology class, location information ontology class, and service information ontology class.

3 is an embodiment of a priority table according to the present invention. Priority table 310 according to the present invention defines the priority of each of the ontology classes 110 that can be selected and provided to the user, and is stored and managed in the ontology DB, to prevent conflicts that may occur when providing a service can do.

For example, as shown in FIG. 3, the priority table 310 defines priorities for at least one user information ontology class, device information ontology class, location information ontology class, and service information ontology class. Of course, the priority may be set and managed by a predetermined quantitative value such as an integer.

Referring to the priority table 310 illustrated in FIG. 3, the first user P1 has a higher priority than the second user P2, and the first service S1 is assigned to the second service S2. The priority is set higher than that, and these priorities are defined and managed by predetermined quantitative values. In addition, the first user P1 has the highest priority in the first location L1, and the first device E1 has the highest priority among the first user P1 and the second user P2.

Meanwhile, the priorities of multiple services are as follows.

That is, the priority of the first multiple services 'E1-L1-S1' and the second multiple services 'E1-L1-S2' among the multiple services selectable by the first user will be described based on the quantitative value. The priority quantification value of the multiple services is the sum of the priority quantification values of 'E1', 'L1' and 'S1', and the priority quantification value of the second multiple service is 'E1', 'L1' and 'S2'. Is the sum of the priority quantitative values.

In other words, the priority quantitative value of the first multiple service is 'E1' because the priority quantitative value 10 ('E1' includes the priority 'P1' and 'P1' has the priority quantitative value 10 is 'E1'. The priority quantitative value of 'is 10), the priority quantitative value of' L1 'is 10 (the same way as' E1' is, and the priority quantitative value of 'L1' is 10), and the priority quantitative value of 'S1' is 10 The sum is 30, and the priority quantitative value of the second multiple service is 25 by the same method as the method of obtaining the priority quantitative value of the first multiple service, so that the first multiple service that can be provided to the first user is obtained. 2 It has higher priority than multiple services.

As described above, the priority among the multiple services is automatically determined by intelligent processing of the home network server 220 based on the priority table 310, not the user's manipulation.

At this time, when the first user wants to receive the third service S3, which is one of the service information ontology classes not provided to the user, through the first device E1 at the first location L1, first, 'E1-L1-S3', which is a third multiple service for one user, is received from the user through the user interface 210, and priority for the third multiple service is given priority over the first and second multiple services. The ranking may be compared to determine a priority for the third multiple service. In addition, the first multi-service or the second multi-service provided by another method is modified to the third multi-service, and the priority of the first multi-service or the priority of the second multi-service is modified according to the modification setting of the multi-service. It may be modified to set the priority of the third multiple services.

Meanwhile, the priority table 310 according to the present invention is merely an example for explaining the present invention, and is stored and managed as an ontology such as the ontology class 110 or the ontology subclass 120 to be referred to and used through object properties. Can be.

4 is an embodiment of a display through a user interface of the present invention. Referring to FIG. 4, ontology classes related to device information, location information, and service information, which are multiple services that a user may receive, are displayed through the user interface 210.

In other words, the home network server 220 confirms user information through a user authentication process through a login process to the server, and extracts multiple services that can be provided to the identified user from the ontology DB to the user interface 210. Display via.

When the user selects a specific ontology class through the user interface 210, the home network server 220 receives a request from the user interface 210, such as the user's selection, and sends the request to the ontology DB according to the received request. Based on the relationship between the ontology class information being stored and managed and each ontology class, information related to the selected ontology class is extracted and displayed through the user interface 210.

An example of providing a home network service is as follows.

First, when the first user is located on the home network, the home network server 220 identifies the first user through the user interface 210 and extracts information about the first user from the ontology DB. The server 220 authenticates the first user through the extracted information and starts a service.

The server 220 secures the first user information ontology class, extracts multiple service ontology classes related to the first user information ontology class from the ontology DB, and transmits the same to the user interface 210. The user interface 210 receives and displays multiple service ontology classes that may be provided to the first user from the server 220.

When the user selects the first location information ontology class among the multiple service ontology classes displayed in the user interface 210, the server 220 confirms that the first location information ontology class is selected from the user interface 210, and determines the relationship. Based on the multi-service ontology classes related to the first location information ontology class, except for the location information ontology classes, it is extracted from the ontology DB and transmitted to the user interface 210. The user interface 210 receives and displays from the server 220 service information ontology classes and device information ontology classes, which are multiple service ontology classes that can be provided to a first user except for location information ontology classes.

Subsequently, when the user selects the first service information ontology class among the multiple service ontology classes displayed on the user interface 210, the server 220 may be provided in the first location information ontology class state from the user interface 210. After confirming that the first service information ontology class is selected, the user interface 210 is extracted by extracting multiple service ontology classes related to the first service information ontology class except the location information ontology classes and service information ontology classes based on the relationship. To send). The user interface 210 receives and displays from the server 220 device information ontology classes, which are multiple service ontology classes that can be provided to a first user except for location information ontology classes and service information ontology classes.

Finally, the user selects the first device information ontology class among the multiple service ontology classes displayed on the user interface 210, so that the server 220 receives the user's selection information from the user interface 210 and according to the selected ontology class. The first service is provided through the first device at the first location.

Of course, the multi-service may be provided through at least one of location information, service information, and device information.

Meanwhile, when the first multiple services are displayed and provided through the user interface 210 as described above, the modification of the provided multiple services and the priority change of the changed multiple services will be described in detail as follows.

First, when a user modifies at least one of the ontology classes of the first multiple service displayed through the user interface 210 to another ontology class, the server 220 changes the first multiple service to the second multiple service. The first multiple services receive the modified information modified by the second multiple services, and modify the first multiple services on the ontology DB that can be provided to the user according to the received modified information to the second multiple services.

Here, modifying multiple services on ontology DB means modifying the relationships among ontology classes belonging to multiple services.

In addition, the home network server 220 may modify and set the priority of the first multiple services according to the priority of the modified second multiple services with reference to the priority table 310 of FIG. 3.

Although the present invention has been shown and described with reference to the preferred embodiments as described above, it is not limited to the above embodiments and those skilled in the art without departing from the spirit of the present invention. Various modifications and variations are possible without departing from the spirit of the present invention and equivalents of the claims to be described below.
