Many process modeling techniques, such as Petri-net, UML Activity Diagram, and EPC, are used to design process models. In this paper, we analyze ubiquitous process design based on workflow patterns. In particular, we focus on process design using active rules that have the form of Event-Condition-Action, and deal with the WS-ECA language, which was devised for ubiquitous web services coordination. We first check whether workflow patterns can be designed with ECA rules, and we then provide WS-ECA representations for ECA rules of the patterns. The contribution of this paper is that ECA rule-based process models were presented based on workflow patterns and they can be a guideline for ubiquitous process modeling.

로봇은 특수 분야에서 일반 산업 및 가정에 이르기까지 다양한 경로를 통해 사람에게 유용한 서비스를 제공해왔다. 하지만 로봇의 아키텍처 및 인터페이스의 비표준화로 인해 호환성 및 생산성의 문제가 야기되었다. 본 논문에서는 ECA규칙을 이용하여 컴포넌트의 동적 추가 및 확장이 가능한 로봇 아키텍처를 제안한다. 센서와 동작기 부분의 인터페이스를 표준화하였으며 ECA규칙 적용을 위한 DB스키마 및 규칙 정보 관리를 위한 테이블 구조를 제시하였다. ECA규칙은 구조가 단순하여 기계학습의 응용에도 적합하다. 제안하는 아키텍처는 컴포넌트 조합이 바뀔 때마다 동적으로 새로운 규칙을 적용할 수 있고 공개된 컴포넌트가 가진 어휘를 이용하여 확장된 규칙을 정의할 수 있다.

As recent business environments are changed and become complex, a more efficient and effective business process management are needed. This paper proposes a new approach to the automatic execution of business processes using Event-Condition-Action (ECA) rules that can be automatically triggered by an active database. First of all, we propose the concept of blocks that can classify process flows into several patterns. A block is a minimal unit that can specify the behaviors represented in a process model. An algorithm is developed to detect blocks from a process definition network and transform it into a hierarchical tree model. The behaviors in each block type are modeled using ACTA formalism. This provides a theoretical basis from which ECA rules are identified. The proposed ECA rule-based approach shows that it is possible to execute the workflow using the active capability of database without users' intervention.

유비쿼터스 환경에서 사용자에게 최적의 서비스를 제공하기 위해서는 사용자 행동 및 서비스 이력을 기반으로 사용자의 상황에 적합한 새로운 서비스 규칙을 발견하는 것이 중요하다. 이 논문에서는 사용자의 상황을 고려하기 위한 컨텍스트 온톨로지를 기반으로 사용자의 행동 및 서비스 패턴을 능동적으로 마이닝할 수 있는 ECA규칙 기반의 시스템 구조를 제안한다.

Wireless sensor network is a technology that collects the information about object in real-time. Sensor data has a characteristic that is generated an unprecedented volume data in short time. Analysis is essential to define the relationship between the data, including more of the data from a large volume data stream which is acquired from the sensor. In order to effectively handle the sensor data stream, in this paper, using ECA rules to organize data in a meaningful and more practical real-time monitoring systems is proposed.

In this paper collaboration of web-based distributed business systems is analyzed and the need of timely collaboration is derived and described in terms of inter-organizational contracts. A method of event-condition-action (ECA) rule based timely collaboration to meet the need and an active functionality component (AFC) to provide the method are proposed. The proposed method supports high level rule programming and event-based immediate processing so that system administrators and programmers can easily maintain the timely collaboration independently to the application logic. The proposed AFC uses HTTP protocol to be applied through firewalls. It is implemented using basic trigger facilities of a commercial DBMS for practical purpose.

The development of IT technology has brought many changes in military operations. For example, the way of transmitting and receiving information from one another has changed. Partiicularly, in the case of the ROK Navy, they utilize encrypted real-time chattig over wire wireless network in operations and tranings. However, text communication is being utilized more in exanging of simple informations, and not for the partical informations required in the operations and exercises, doctrines and guidebooks are still being used in these cases. Therefore, I have designed a rule-based engine which can provide real-time informations by linking ECA rules to text communication, and it has been verified by running virtual scenarios. As a rusult, this engine showed an accuracy of 83%.

능동데이터베이스(active database)는 일반 데이터베이스와 능동 규칙을 결합한 형태로서, 데이터베이스 스스로 상태 변화에 대응한 조치를 취할 수 있는 시스템을 말한다. 이러한 능동데이터베이스에서는 규칙의 설계가 데이터베이스 활용의 큰 비중을 차지한다. 이러한 규칙의 효율적인 설계를 위해서는 simulator의 도움이 필요하다. 이에 본 논문에서는 이러한 능동데이터베이스의 규칙을 효율적으로 설계하기 위한 도구의 설계에 대해서 연구한다.

ECA 규칙에 근거한 능동성 개념은 실시간 데이터베이스에서 중요한 연구 분야이다. 기존에 연구된 실시간 동시성 제어 기법들은 능동성 개념을 지원하지 않기 때문에 실시간 능동 데이터베이스를 위한 동시성 제어 기법을 제안한다. 기존에 제안된 실시간 다중버전 동시성 제어 기법을 능동 데이터베이스에 적용하여 시간 제약과 능동 규칙을 동시에 만족하도록 고안하였다. 특히, 본 연구에서 제안한 동시성 제어 기법은 ECA 규칙에 의해서 실행된 트랜잭션들 사이의 선행관계와 능동관계를 연관시켜 데이터베이스의 일관성을 유지한다.

Timely collaboration among businesses is required these days such as in B2B E-Commerce. That is, emergency requests or urgent information among businesses should be processed in an immediate mode. In this paper we investigate the semantics on timing constraints of timely collaboration among businesses in terms of event, data, and action and present ECA rule construction related to the timing constraints and its violation. The prototype is implemented using web-based active functionality component.
