The present invention relates to an inference device for providing an adaptive service in a knowledge-based home network, and more particularly, based on a user's profile, location, and behavior pattern in a home network system based on a ubiquitous environment. The present invention relates to an inference device that enables a user to provide a desired service.

Ubiquitous environment refers to an environment in which a user can freely access a network and receive various services regardless of a place without a computer or a network. In other words, ubiquitous refers to an environment in which information can be exchanged economically and conveniently at any time, anywhere, any device, and any device.

The home network, which opens the ubiquitous era, is based on wired and wireless communication networks such as mobile communication and high-speed internet, and it provides a wide range of services regardless of device, time, and place as A / V, data communication, and information appliances are connected to each other through a network. It is an environment that can provide a safe and smart automation service because it can be managed throughout the house through a central home server. In addition, its purpose is to maximize the user's convenience by providing services through complex and knowledgeable interoperability with various user requests and environments.

As technology research for the development of home network is accelerating, in order to build a future-oriented home network, the physical space to which devices are connected in a simple form must be transformed into an intelligent ubiquitous environment, which is a more intelligent and adaptive computing environment. do. In order to realize such an intelligent environment, autonomous and diverse entities need to recognize and exchange common contexts, and context-aware technology to provide optimal services for a given situation. . In other words, it should not be a passive environment that operates only by a user's direct service request, but an environment that can be provided with an 'Invisible Service' that provides services without the user's awareness.

In particular, the home network system based on the ubiquitous environment provides appropriate information in various input / output (Multimodal) methods according to the tastes, interests, and contexts of each user, and relates the interests and knowledges of each user. It can be expressed through ontology. In addition, by collecting, analyzing, processing, and processing information collected from sensors in the home, the voice, text, and graphics are reported, and based on such information, an adaptive user-oriented best service can be provided. In order to further advance such services, it is urgently required to develop a reasoner that can infer each event when an event occurs in a home network environment.

By the way, the current reasoning device (Reasoner) provides a basic service according to the location of the user based on the "Rule-Based Engine", or the service of the service based on the static information stored as a profile (Profile) through the "Reasoning Engine" Provision is being developed mainstream.

However, in the current "Rule-Based Engine", how general the rules used are, so they can be applied in various ubiquitous environments and home networks, and the radius of the user's actions that can be included in the rules. It is becoming a form based on the provision of specialized services that are lacking in terms of diversity of services and services. In addition, the current "Reasoning Engine" alone can provide a service for the user's static pattern, but it is insufficient for the operation of the home appliance or to configure an efficient service.

Therefore, these two engines must be operated in one module to infer contextual services. However, in order to infer a service, basic system rules for inferring a situation in accordance with the inference operation framework and needs of a module and implementation of a service rule for providing and operating a service are required. However, these rules are currently limited in scope and limited to basic services.

Therefore, based on the existing "Reasoning Engine" and "Rule-Based Engine" to provide the necessary services according to the user's location coordinates or requests, or to provide a service for the static pattern specified by the user by inferring the time and space relationship The development of the reasoning engine is urgently needed.

The present invention has been proposed to meet the above demands, and provides an inference device that enables a user to provide a desired service based on a user's profile, location, and behavior pattern in a home network system based on a ubiquitous environment. The purpose is.

The present invention allows a user to receive a desired service based on his / her profile, location and behavior pattern, and stores a basic profile for the user and home appliances, based on the user's profile. We want to provide a service for patterns according to basic rules that will operate on propensity and movement.

To this end, in the present invention, various and efficient query API (Application) in the "Reasoning Engine" in order to solve the problems of vulnerabilities and constraints in providing various and general services generated in the existing reasoning device (Reasoner) Programming Interface) Implementation and System & Service Rule are systematically implemented.

In this case, the Query API enables faster and more effective relationship inference about profiles. In addition, by giving priority to each rule applied through a system rule, the rule is organized, and the applicability of each rule is improved by increasing the applicability between the rules. Enable reuse of rules. In addition, the service rule is a general configuration, and is not limited to a specific region, but is configured to provide various services only by changing a profile.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of an inference apparatus for providing a user adaptive service according to the present invention.

As shown in FIG. 1, the inference apparatus for providing the user adaptive service in the knowledge-based home network according to the present invention includes a query input unit (Query API) for converting and transmitting an input query to be applied to inference ( 11) a fact translator 12 for converting and storing associations between user profiles, appliances, and services into facts applicable to inference, and system rules for situation inference ( Rule Translator 13 for transforming and storing System Rule and Service Rule for service provision and operation so that it can be applied to inference, and user command and sensed data. Context Translator 14 for converting the data into a context that can be applied to inference, and save and update dynamic changes to the fact and analysis of the query in real time. In addition, the reasoning engine 15 for constructing service facts individually for effective analysis management, application of relevant rules to facts, facts and Inference of pattern matcher 16 and inference of pattern matcher 16 to infer context-adaptive services suitable for users through inference of relation between rules and inference of results of context An execution engine 18 for executing a service according to the result is included. In addition, the rule for the policy inferred result between the rules through the pattern matcher 16 (that is, the configuration and priority of rules for priority management of various rules themselves and application of the same rules) It further includes a proposal module (Agenda) for applying the rank change and update process).

The Query API 11 allows the Reasoning Engine 15 to understand queries sent from other modules (ie, Miner, Interfacing Engine). Convert and send.

In fact, the fact translator 12 uses the Knowledge Repository's Ontology Context Model to establish an association between user profiles, appliances, services, and events. The value converted in the triple form (association value) is converted into fact (Fact) and stored so that the pattern matcher 16 can apply it to inference.

The rule translator 13 converts the rule that is stored in the rule set of the knowledge repository so that the pattern matcher 16 can apply it to inference. Manage.

The context translator 14 converts the information (sensing data) and the user command transmitted through the sensor to be used by the pattern matcher 16.

The Reasoning Engine 15 manages the query in real time through the analysis and the dynamic changes to the facts and saves and updates the data, and provides individual service facts for effective analysis / management. Configure (Service Fact). And a data filtering function.

Based on the information transmitted through the translators 12 to 14 (ie, association values, facts, rules, contexts, and the like), the pattern matcher 16 may be connected to facts. Infer the context-sensitive service that is suitable for the user by applying the relevant rule for the user and the result inference about the relation between the fact and the rule, the command and the request (that is, the context). . In addition, the fact values for Priority and Access Level, the priority for applying Priority and the handling of redundancy, the priority for Conflict occurrence ) Based on the rule, and send after inferencing the user and location, the differential application through the relevant information, the application of the user's privacy (Fact) to the fact (Fact).

At this time, the agenda module 17 applies a policy on the inferred result between rules for the transmitted result. In this case, the policy is applied to prioritize various rules and to configure and update priorities of the rules for updating the same rules. .

The resulting information, which is passed through the Agenda module 17, is sent to the Execution Engine 18, which is insufficient for more detailed or dynamic configuration of the facts or information and for the accurate provision of services. Context is redirected to the Reasoning Engine 15 for re-inference and application of other rules, or if it contains a context that requires inferred results, the Service Manager It includes the function to send.

Here, the service manager is capable of integrated management of each service unit, and maintains and observes each service unit, establishes an action plan, and operates each action according to a schedule.

In this way, it is possible to support the improvement of inference accuracy, enhancement of service provision range, and efficiency through reuse of rules, compared to existing reasoners.

For example, when the sensor recognizes the user's appearance and delivers it to the system, the reasoning apparatus according to the present invention searches the user's profile to determine the user's disposition and provides basic services for the user and the location. Infer home appliances for the purpose and provide appropriate services. In addition, the service can be provided after checking the existing service with respect to the user's command and checking the conflict. In addition, for multiple users, in order to provide each requested service or basic service, the priority of the user and the priority of the access level and space for the home appliance to provide the service are set. Inferring the result through the transmission.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
