Bhargava, Hemant K. and Feng, Juan (2002): Paid placement strategies for internet search engines. In: Proceedings of the 2002 International Conference on the World Wide Web 2002. pp. 117-123. Available online

Internet search engines and comparison shopping have recently begun implementing a paid placement strategy, where some content providers are given prominent positioning in return for a placement fee. This bias generates placement revenues but creates a disutility to users, thus reducing user-based revenues. We formulate the search engine design problem as a tradeoff between these two types of revenues. We demonstrate that the optimal placement strategy depends on the relative benefits (to providers) and disutilities (to users) of paid placement. We compute the optimal placement fee, characterize the optimal bias level, and analyze sensitivity of the placement strategy to various factors. In the optimal paid placement strategy, the placement revenues are set below the monopoly level due to its negative impact on advertising revenues. An increase in the search engine's quality of service allows it to improve profits from paid placement, moving it closer to the ideal. However, an increase in the value-per-user motivates the gatekeeper to increase market share by reducing further its reliance on paid placement and fraction of paying providers.

Bhargava, Hemant K. (1995): Using Quiddities for Detecting Semantic Conflicts in Information Systems. In Journal of Organizational Computing, 5 (4) pp. 379-400.

When multiple people are involved in designing an information systems application, there can be conflicts in terminologies used by them for various elements represented in the application. These problems are recognized in database design, federated databases, knowledge-based systems, mathematical modeling systems, and cooperative work systems. A computer-based method for detecting such naming conflicts, once the users have declared certain additional information for all of the represented elements, is presented. The approach extends earlier work by Bhargava, Kimbrough, and Krishnan in the context of model integration. There is a description of how this additional information (called quiddity) is to be formulated and represented, and several automated procedures are presented that detect naming conflicts on the basis of this information. The practical utility of this approach is also discussed.

Bhargava, Hemant K., Krishnan, Ramayya and Whinston, Andrew B. (1994): On Integrating Collaboration and Decision Analysis Techniques. In Journal of Organizational Computing, 4 (3) pp. 297-316.

We discuss how methods for computer-based collaboration and computer-aided decision analysis may be combined to yield a new generation of decision support systems. We examine the role of these technologies using a three-phase model (problem definition; problem structuring; modeling/analysis) of decision making activities. We argue that decision making is a recursive mesh of these three phases; i.e., each phase involves argumentation/discussion, structuring, and analysis. Representations and methods suited to one kind of activity (e.g., discussion) are not directly suited to the others. Decision support systems, therefore, should facilitate the use of all of these methods in a way that information represented under each of them may be combined effectively, supporting the decision makers in switching from one activity to another.
