A Methodology to Create Legal Ontologies in a Logic Programming Based Web Information Retrieval System

Web legal information retrieval systems need the capability to reason with the knowledge modeled by legal ontologies. Using this knowledge it is possible to represent and to make inferences about the semantic content of legal documents. In this paper a methodology for applying NLP techniques to automatically create a legal ontology is proposed. The ontology is defined in the OWL semantic web language and it is used in a logic programming framework, EVOLP+ISCO, to allow users to query the semantic content of the documents. ISCO allows an easy and efficient integration of declarative, object-oriented and constraint-based programming techniques with the capability to create connections with external databases. EVOLP is a dynamic logic programming framework allowing the definition of rules for actions and events. An application of the proposed methodology to the legal web information retrieval system of the Portuguese Attorney General’s Office is described.     

基于数据依赖图的主域变量识别方法*

随着企业/组织中大量遗留系统的产生,遗留系统的业务逻辑提取技术也受到越来越多的关注。对于提取业务逻辑,主域变量是一个很好的入口点。在应用领域中,主域变量对应着重要的业务对象,分析主域变量的状态变化以及主域变量间的关系可以获得大部分的业务逻辑。但现今,国内外对于主域变量识别技术的研究大多只提到它的重要性,并没有提出如何提取主域变量的具体方法。给出了一种基于数据依赖图(DDG)的主域变量识别方法,并将该方法运用到一大型遗留系统的业务逻辑提取中。实践证明该方法大大提高了提取效率,并有效地降低了出错的可能性。     

Enterprise Modeling and Decision-Support for Automating the Business Rules Lifecycle

Business rules represent policies, procedures and constraints regarding how an enterprise conducts its business. To get the full benefits of modeling business rules requires an approach to managing them through their full lifecycle, from acquisition through deployment and evolution. The research reported in this paper is aimed at determining what infrastructure capabilities are needed to provide this lifecycle support. The solution embodies a modeling framework that captures the structure of the enterprise, in terms of which the business rules can be expressed, and decision-support capabilities for reasoning about and deriving business rules. The paper demonstrates the possibility of automatic support of the business rules lifecycle by automatically generating business rules from the captured information, along with data representing domain assumptions in a case study (the London Ambulance System). A system was implemented to illustrate the methodology and to demonstrate the feasibility of the approach. The methodology also gives guidance on how to deal with pragmatically important situations such as rules that involve both automated and human tasks, nondeterministic rules, and goal-oriented versus operational rules.     

Domain Modelling and the Co-Design of Business Rules in the Telecommunication Business Area

This paper discusses the development of an enterprise domain model in an environment where part of the domain knowledge is vague and not yet formalised in company-wide business rules. The domain model was developed for a young company starting in the telecommunications sector. The company relied on a number of stand-alone business support systems and sought for a manner to integrate them. There was opted for the development of an enterprise-wide domain model that had to serve as an integration layer to coordinate the stand-alone applications. A specific feature of the company was that it could build up its information infrastructure form scratch, so that many aspects of its business were still in the process of being defined. The paper will highlight parts of the Enterprise Model where there was a need for co-designing business rules together with the domain model. A result of this whole effort was that the company got more insight into important domain knowledge and developed a common understanding across functional areas of the way of doing business.

EFSOC: A Layered Framework for Developing Secure Interactions between Web-Services

Enterprises are rapidly extending their relatively stable and internally-oriented business processes and applications with loosely-coupled enterprise software services in order to support highly dynamic, cross-organizational business processes. These services are no longer solely based on internal enterprise systems, but often implemented, deployed and executed by diverse, external service providers. The ability to dynamically configure cross-organizational business processes with a mixture of internal and external services imposes new security requirements on existing security models. In this paper, we address the problem of defining and enforcing access control rules for securing service invocations in the context of a business process. For this purpose, we amortize existing role-based access control models that allow for dynamic delegation and retraction of authorizations. Authorizations are assigned on an event-driven basis, implementing a push-based interaction protocol between services. This novel security model is entitled the Event-driven Framework for Service Oriented Computing (EFSOC). In addition, this article presents an experimental prototype that is explored using a realistic case study. This work has been partially funded by the Netherlands Organization for Scientific Research (NWO) as part of the PRONIR project. Recommended by: Asuman Dogac

Reusing enterprise models to build platform independent computer models

Enterprises use enterprise models to represent and analyse their processes, products, decisions, organisation, information flows, etc. Nevertheless, the enterprise knowledge that exists in enterprise models is not used beyond these purposes. The main goal of this paper is to present a framework that allows enterprises to reuse enterprise models to build software. The framework includes these dimensions: (1) a methodology that guides the use of the other dimensions in the reutilisation of enterprise models in software generation; (2) a set of metamodels to represent enterprises at the Computation Independent Model (CIM) level; (3) a modelling guide to make enterprise models using the metamodels proposed in this paper; (4) an extraction algorithm to discriminate the part of the CIM model to reuse; and (5) a set of transformation rules to reuse enterprise models to build Platform Independent Models. In addition, a case example is shown to validate the work that was carried out and to identify limitations.

在利用Agent模板语言(APL)进行多Agent系统(MAS)快速开发的基础上,提出了基于APL和多Agent系统的面向过程的企业应用集成框架。根据业务过程的一般结构与特征,框架采用分层的业务逻辑模型,实现业务逻辑与业务执行的分离。通过这种方式避免企业业务流程的局部变化引起系统整体结构的较大变动。同时在利用APL对业务过程进行描述的过程中引入了角色与结构化活动,一方面使得用户能够根据角色把业务过程分解为子过程,另外结构化活动的引入弥补了APL在描述复杂业务流程方面的不足。通过这种方式,使得用户能够利用所提出框架,提高企业应用集成系统的开发效率,增强系统的灵活性。     

A methodology and tool support for managing business rules in organisations

Business rules are evidently important for organisations as they describe how they are doing business. Their value has also been recognised within the information system (IS) domain, mostly because of their ability to make applications flexible and amenable to change. In this paper, we propose a methodology that helps business people and developers to keep business rules at the business level inline with the rules that are implemented at the system level. In contrast to several existing approaches that primarily focus on business rules in the scope of an application, our methodology addresses the entire IS of an organisation. The paper also describes requirements for a tool support that would be appropriate to support the methodology.
