A method and a system for evaluating the quality of a contribution made by a user in a distributed online community framework are disclosed. The quality of contribution is assessed by creating a reputation profile of the user across multiple online communities. The reputation profile contains a reputation score indicating the credibility of the user, user identification information, user participation statistics and user contribution information. Such reputation score is calculated based on the feedback provided by other users for the contribution made by the user. The system also allows maintaining and publishing a unique reputation profile across the distributed online communities. Maintaining the reputation profiles incentivizes users to contribute better quality content. This improves the overall quality of the community discourse.

A computer program product is provided as a business rating system to rank business that are relevant to a given Internet search topic. Business ratings are stored in a ranking repository that can be optionally searched by the user along with a user-defined search engine query. The business ratings are compiled from on-line questionnaires attached to the search engine results and/or on-line surveys obtained through other web based rating services. The business ratings assess the quality of the businesses in terms of “interactive” criteria such as customer satisfaction, professionalism, and cost and ease of use of the businesses' products or services. The business rating system is comprised of an on-line indexing engine, a query transformer, a search results transformer, a ranking based result sorter, an on-line ranking system, a metadata repository, and an on-line ranking repository. The business rating system integrates the ratings with the search results, and ranks the search results based on such business ratings. In this manner, the user of a search engine receives feedback from other users about businesses of interest. Eventually, businesses with higher ratings will be ranked at the top of the search list, while business with lower ratings will be ranked lower.

A method for producing an assured image from image data that is transferred from a first entity to a second entity acquires image data, transfers the acquired image data from the first entity to the second entity, forms secure assurance data according to image quality measurements obtained from the acquired image data, and forms an assured image that includes the acquired image data and the secure assurance data. At least one image quality message is generated that indicates the transfer of the acquired image data from the first entity to the second entity and is representative of the image quality measurements. The at least one image quality message is presented to at least one of the first entity and the second entity.

An open community model for information exchange enables individuals to plan and attain superior outcomes in a dynamic environment. A continually “world model” maintains information about the dynamic environment that is valuable for individuals of the open community. An open community model application publicizes a specification of relevant types of information it receives from suppliers and provides to consumers. Suppliers provide information consistent with the specification. Consumers utilize received information to reduce uncertainties or errors in the assumed environment so they can generate improved plans or improve their expected outcomes. Consumers give feedback to the open community model about the quality of information they received. A “world model” application combines information received to update and improve its understanding of the dynamic environment and its estimates of relevant parameters. The community model simplifies the creation and operation of information markets where innovative products are naturally selected and economically reinforced.

The invention provides polymers comprising pendent photochrome or near IR dye groups, as well as polymeric matrices made from these polymers, which can be used as or in association with a medical article. The polymers can be synthesized using methods that facilitate the preparation of medical articles having good biocompatibility. Exemplary polymeric matrices are in the form of lubricious coatings on medical devices, such as catheters. Visualization by irradiation of the photochrome or near IR dye can improve detection of the polymeric matrix on a device or in the body. This, in turn can improve aspects of a medical procedure, such as device insertion or matrix formation, as well as being useful for assessing the quality of the matrix.

A processing system employs a processing tool to process workpieces, for example cold working holes and/or installing expandable members into holes. Sensors sense various aspects of the processing.
