Integrated Support for e-Commence and e-Procurement Based on Database for Business Rules

发展电子商务、电子采购、电子政务等技术，可以促进全社会生产力的提高，提高经济运行效率。在本研究中，我们专注于建立销售合同的营销功能，并支持销售合同的执行。在企业对企业(B2B)电子商务和电子采购中，销售商品不仅要根据价格进行比较，还应该根据各种类型的附加值、折扣规则和取消政策进行比较。将这些业务规则用逻辑语言表示并存储在数据库中，可以用于开发包括拍卖在内的营销应用程序，以及基于销售合同生成工作流定义等。这类文本，如机票和租车合同，通常都是用统一的句子写成的，并提供了转换TE…更多的模板可以极大地帮助转换任务。这些模板以约束语言生成业务规则，并存储在本研究开发的动态约束数据库中。可以查询数据库中的那些规则以获得逻辑可满足性和隐含。为了更好地理解业务规则的趋势和特点，提出了一种构建反映业务规则属性间关联程度的用户界面的方法。使用此界面，用户可以很容易地构建用户可配置的商品，如组装PC，因为我们的界面可视化了业务规则属性之间的相关性，这反映了如何独立选择部件，从而减少了约束违规。对于组织间流程协作，我们开发了一个电子合同数据库，其中包含协议、责任、最后期限、例外等条款。通过将组织内工作流程与这些电子合同联系起来，我们可以监控电子合同的执行情况。我们还开发了查询工作流案例以获取相关电子合同调用的方法，以及针对电子合同关系查询类似的工作流案例的方法。较少

Developing technologies for e-commerce, e-procurement and e-government can contribute for promoting productivity of the entire society as well as improving efficiency of economy. In this research, we focused on marketing functionality for establishing selling contracts, and supporting execution of selling contracts. In business-to-business (B2B) e-commerce and e-procurement, selling goods shall be compared not only by price, but also by various types of added values, discount rules, and cancel policies. Representing such business rules in a logical language and storing them in a database can be utilized for developing applications such as marketing including auctions, generating workflow definitions based on selling contracts, and so on.In this research, we developed a technology for extracting business rules from natural language texts in web pages. Such texts, like airline tickets and rent-a-car contracts, are often written in mostly uniform sentences, and providing transformation te … More mplates can greatly help the transformation task. The templates produce business rules in a constraint language and stored in a dynamic constraint database developed in this research. Those rules in the database can be queried for logical satisfiablity and implication. We showed evaluation results as well as query optimization methods.For understanding tendencies and characteristics of business rules, we proposed a method for constructing a user interface which reflects degree of relevancy between attributes of business rules. Using this interface, user-configurable goods, such as assembling PCs, can be easily constructed by users, because our interface visualizes relevancy between attributes of business rules, which reflects how parts can be independently chosen, thus reducing constraint violations.,For inter-organizational process collaboration, we have developed a database of e-contracts, where e-contracts hold clauses of agreements, duties, deadlines, exceptions, and so on. By linking intra-organizational workflows with these e-contracts, we can monitor execution of e-contracts. We also developed methods for querying workflow cases to obtain relevant e-contract calluses, and querying similar workflow cases in respect to e-contract relationships. Less
