1,664 | 0 | Moral Sentiments in Multi-Agent Systems We present a simulation of a society of agents where some of them have "moral sentiments" towards the agents that belong to the same social group, using the Iterated Prisoner's Dilemma as a metaphor for the social interactions. Besides the well-understood phenomenon of short-... | [

1,666 | 4 | Interactive Maps for a Digital Video Library The Informedia Digital Video Library contains over 1200 hours of video. Through automatic processing, descriptors are derived for the video to improve library access. A new extension to the video processing is the extraction of geographic references from these descriptors. T... | [

1,667 | 3 | Incremental Maintenance for Materialized Views over Semistructured Data Semistructured data is not strictly typed like relational or object-oriented data and may be irregular or incomplete. It often arises in practice, e.g., when heterogeneous data sources are integrated or data is taken from the World Wide Web. Views ... | [

1,670 | 3 | Answering Queries by Semantic Caches There has been growing interest in semantic query caches to aid in query evaluation. Semantic caches are simply the results of previously asked queries, or selected relational information chosen by an evaluation strategy, that have been cached locally.
