| Research Abstract |
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

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
