In this work we analyzed the interfaces of several popular search tools from the user's point of view, and collected individual feedback in order to determine whether it is possible to improve interface design.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Effective bandwidth utilization is important for any distributed system. In addition, specific issues need to be addressed in order to assimilate spatio-temporal data from multiple sources. These issues include resolution of differences in datum, map-projection and time coordinate. Reduction in the complexity of data formats is a significant factor for fostering interoperability. Simplification of training is important to promote usage of the distributed system. We describe techniques that revolutionize Web-based delivery of meteorological and oceanographic data to address needs of the Naval/Marine user.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

In this paper, we propose two new metrics to evaluate the performance of information retrieval: diversity, which measures the topic coverage of a group of documents, and information richness, which measures the amount of information contained in a document. Then we present a novel ranking scheme, Affinity Rank, which utilizes these two metrics to improve search results. We demonstrate how Affinity Rank works by a toy data set, and verify our method by experiments on real-world data sets.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Here we introduce a local adaptive routing algorithm used to dynamically change the topology of the peer network based on a simple learning scheme driven by query response interactions among neighbors. We test the algorithm via simulations with 70 model users based on actual Web crawls. We find that the network topology rapidly converges from a random network to a small world network, with emerging clusters that match the user communities with shared interests.","PeriodicalId":409891,"journal":{"name":"WWW Alt.
