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

发展电子商务、电子采购和电子政务技术，有助于提高整个社会的生产力和经济效率。在这项研究中，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，销售商品不仅要通过价格进行比较，还要通过各种附加值、折扣规则和取消政策进行比较。用逻辑语言表示这些业务规则并将其存储在数据库中可以用于开发应用程序，例如包括拍卖在内的市场营销，基于销售合同生成工作流定义等。在这项研究中，我们开发了一种从Web页面中的自然语言文本中提取业务规则的技术。这类文本，如机票和租车合同，通常都是用统一的句子写的，并提供转换功能。 ...更多信息 mplates可以极大地帮助转换任务。模板产生的业务规则的约束语言和存储在一个动态的约束数据库在这项研究中开发。这些规则在数据库中可以查询逻辑可满足性和蕴涵。给出了评价结果和查询优化方法，提出了一种基于业务规则属性间关联度的用户界面构建方法，以更好地理解业务规则的倾向性和特征。使用这个接口，用户可以很容易地构造用户可配置的商品，例如组装PC，因为我们的接口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零件，从而减少了约束违反。为了实现组织间的流程协作，我们开发了电子合同数据库，在电子合同中包含协议、责任、期限、例外等条款。通过将组织内的工作流与这些电子合同连接起来，我们可以监控电子合同的执行情况。我们还开发了用于查询工作流案例以获得相关电子合同调用的方法，以及查询关于电子合同关系的类似工作流案例的方法。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
