Abstract: A robust process for automating the tuning and maintenance of decision-making systems is described. A configurable multi-stage mutation-based evolutionary algorithm optimally tunes the decision thresholds and internal parameters of fuzzy rule-based and case-based systems that decide the risk categories of insurance applications. The tunable parameters have a critical impact on the coverage and accuracy of decision-making, and a reliable method to optimally tune these parameters is critical to the quality of decision-making and maintainability of these systems.

Abstract: A delegated administrative tool for administrating information in a database directory using at least one arbitrary group of users. The delegated administrative tool enables an administrator to form administrative domains and sub-domains using the at least one arbitrary group of users. Also, the delegated administrative tool enables an administrator to delegate administration and various types of administrative authority to other users within a community of users.

Abstract: Searching and matching a set of query strings used for accessing information in a database directory. In this disclosure, a user community administration tool queries a database directory containing user information associated with a user community. In the user community administration tool, there is an input query generation component that generates an input query having a search pattern that includes a combination of attribute names, logical, operators and attribute values. An accessing component accesses a library of queries used for accessing the user information in the database directory. A partitioning component partitions each of the queries in the library into logical units. Each logical unit comprises a combination of an attribute name, logical operator and attribute value. A comparing component compares the search pattern of the input query to each partitioned logical unit for each of the queries in the library.

Abstract: A delegated administrative tool for administrating information in a database directory using attribute permissions. The delegated administrative tool enables an administrator to form administrative domains and sub-domains having user attribute permissions that define administrative operations that an administrator can and cannot perform on a user attribute. Also, the delegated administrative tool enables an administrator to define restricted values for assigning to the user attributes.

Abstract: A delegated administration tool for administrating information in a database directory. The delegated administration tool enables an administrator to delegate administration and various types of administrative authority to other users within a community of users. In particular, an administrator with proper authority may create new administrative domains and assign authority referred to as delegation authority and edit authority to other users. The creation of additional administrative domains and the assignment of the delegation authority and edit authority can continue to an arbitrary level within the community.

Abstract: Establishment and maintenance of a managed community. In this disclosure there is an approach and tool that enables an administration tool to manage communities whose information resides in separate and differently structured directories and databases. In addition, this disclosure describes an approach and tool that enables an administration tool to establish information to be managed from the broad range of directories and databases, which includes defining information that is to be managed and information that is not to be managed and the discovering of new information to manage.
