项目摘要

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

发展电子商务、电子采购、电子政务等技术，有助于提高整个社会的生产力，提高经济效率。在本研究中，我们重点关注用于建立销售合同和支持销售合同执行的营销功能。在企业对企业（B2B）电子商务和电子采购中，销售商品不仅要比价格，还要比各种附加值、折扣规则、取消政策等。用逻辑语言表示此类业务规则并将其存储在数据库中，可用于开发应用程序，例如营销（包括拍卖）、基于销售合同生成工作流定义等。在本研究中，我们开发了一种从网页中的自然语言文本中提取业务规则的技术。诸如机票和租车合同之类的文本通常都是用基本统一的句子编写的，提供转换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这些规则的逻辑可满足性和含义。我们展示了评估结果以及查询优化方法。为了了解业务规则的趋势和特征，我们提出了一种构建反映业务规则属性之间的相关程度的用户界面的方法。使用此界面，用户可以轻松构建可配置的商品，例如组装 PC，因为我们的界面可视化业务规则属性之间的相关性，这反映了如何独立选择零件，从而减少约束违规。对于组织间的流程协作，我们开发了一个电子合同数据库，其中电子合同包含协议、职责、截止日期、例外等条款在。通过将组织内部的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程案例以获得相关电子合同调用的方法，以及查询有关电子合同关系的类似工作流程案例的方法。较少的
