AAAI Conferences

Several authors (Keller and Winslett 1985, Winslett 1988, Katsuno and Mendelzon 1989, Morreau and Rott 1991) have recently argued for a distinction in the way beliefs are updated with new information. They distinguish between information that tells the agent that the world has changed over time and information that fills in or corrects the agent's picture of the world at a particular time. Similarly, one might wish to give an account of intentions and intention revision; our plans alter in the face of both kinds of information. Nobody, however, to our knowledge has worked on integrating belief revision and updating with the revision of intentions, and all of the work on belief revision mentioned above falls to make explicit the important interaction of time, belief and change. Our paper gives a unified treatment of belief change and intention revision within a dynamic logic of belief and intention.

Below I will analyze defensible inferences underlying the interpretation of conversational implicatures and presuppositions; a nonmonotoniconsequence notion will lead from premises including pragmatic generalizations to conclusions about how those sentences are best interpreted..



Towards a Logical Theory of Practical Reasoning

AAAI Conferences

However, despite a tradition that continues to the present, logicians have not produced formalisms that could be considered of any use in designing an agent that needs to act intelligently, or in helping an intelligent agent to evaluate its reasoning about action. In contrast, the decision-theoretic paradigm that grew out of the economic tradition is widely applied in many areas, including AI, and has dominated recent philosophical thinking about practical reasoning, without serious competition from the logical tradition. This lack of progress is largely due to the unavailability of qualitative mechanisms for dealing with the appropriate inference procedures. To handle even the simplest cases of practical reasoning, it is essential to deliver a reasoning mechanism that allows practical conclusions to be nonmonotonic in the agent's beliefs.


After Motel 6 immigrant arrests, hotels explain how they'll protect guest information

Los Angeles Times

Corporate leaders at Motel 6 say employees will no longer volunteer guest information to U.S. Immigration and Customs Enforcement agents after news reports that motel workers were reporting on guests in Phoenix. Corporate leaders at Motel 6 say employees will no longer volunteer guest information to U.S. Immigration and Customs Enforcement agents after news reports that motel workers were reporting on guests in Phoenix. An outcry over Phoenix-area Motel 6 employees turning over guest information to immigration officers without a warrant has prompted hotel industry officials to urge all owners to protect guest information. On Wednesday, Motel 6 corporate leaders promised to put a stop to such practices throughout their chain of 1,400 hotels. According to the Phoenix New Times, which first reported the story, workers at the Motel 6 inns routinely sent guests' names to Immigration and Customs Enforcement officials without the federal agency showing a warrant.
