Incompleteness in information integration

Proceedings of the VLDB Endowment, 2008
Information integration is becoming a critical problem for both businesses and individuals. The data, especially the one that comes from the Web, is naturally incomplete, that is, some data values may be unknown or lost because of communication problems, hidden due to privacy considerations.

The Robustness of Equilibria to Incomplete Information [PDF]

Econometrica, 1997
Summary: A number of papers have shown that a strict Nash equilibrium action profile of a game may never be played if there is a small amount of incomplete information (see, for example, Carlsson and van Damme (1993)). We present a general approach to analyzing the robustness of equilibria to a small amount of incomplete information. A Nash equilibrium

Bargaining under Incomplete Information

Operations Research, 1983
This paper presents and analyzes a bargaining model of bilateral monopoly under uncertainty. Under the bargaining rule proposed, the buyer and the seller each submit sealed offers that determine whether the good in question is sold and the transfer price.

Incomplete Information in Relational Databases

Journal of the ACM, 1984
ABSTRACT This paper concerns the semantics of Codd's relational model of data. Formulated are precise conditions that should be satisfied in a semantically meaningful extension of the usual relational operators, such as projection, selection, union, and join, from operators on relations to operators on tables with “null values” of various kinds ...

On deductive databases with incomplete information

ACM Transactions on Information Systems, 1995
In order to extend the ability to handle incomplete information in a definite deductive database, a Horn clause-based system representing incomplete information as incomplete constants is proposed. By using the notion of incomplete constants the deductive database system handles incomplete information in the form of sets of possible values, thereby ...

Stochastic Programs with Incomplete Information

Operations Research, 1976
This paper treats a simple recourse problem. We consider the problem of reducing the feasible set into a smaller efficient set when partial information about the random parameters is known. We analyze some examples and give applications to stochastic programs with compete information.

Dynamic scheduling with incomplete information

Proceedings of the tenth annual ACM symposium on Parallel algorithms and architectures - SPAA '98, 1998
We consider the following scheduling problem: Our goal is to execute a given amount of arbitrarily decomposable work on a distributed machine as quickly as possible. The work is maintained by a central scheduler that can assign chunks of work of an arbitrary size to idle processors. The difficulty is that the processing time required for a chunk is not

games with incomplete information

1987
Classical economic models almost universally assume that the resources and preferences of individuals (or firms) are known not only to the individuals themselves but also to their competitors. In practice, this assumption is rarely correct. Once the attempt is made to include uncertainty (not just about the environment but also about other strategic ...

The Value of Information in Negotiations with Incomplete Information

2006 International Conference on Information Technology: Research and Education, 2006
The paper considers bilateral negotiations between a buyer agent and a seller agent, where incomplete information exists on the reservation price of both agents. We analyzed a symmetrical negotiation model in which delay is the only signalling device.

Sequential defaults and incomplete information

The Journal of Risk, 2004
We propose a multi-firm first-passage credit model in which investors have incomplete information. In this model, investors observe neither a firm's value nor its default barrier. The model accounts for the short term risk inherent in default events, the market-wide impact of defaults on security prices due to counterparty relations among firms, and ...
