Agents and the Semantic Web

by James Hendler - IEEE INTELLIGENT SYSTEMS , 2001
"... Many challenges of bringing communicating multiagent systems to the Web require ontologies. The integration of agent technology and ontologies could significantly affect the use of Web services and the ability to extend programs to perform tasks for users more efficiently and with less human interve ..."

Extracting Relations from Large Plain-Text Collections

by Eugene Agichtein, Luis Gravano , 2000
"... Text documents often contain valuable structured data that is hidden in regular English sentences. This data is best exploited if available as a relational table that we could use for answering precise queries or for running data mining tasks. We explore a technique for extracting such tables fr ..."

introduces novel strategies for generating patterns and extracting tuples from plain-text documents. At each iteration of the extraction process, Snowball evaluates the quality of these patterns and tuples without human intervention, and keeps only the most reliable ones for the next iteration

ALLIANCE: An Architecture for Fault Tolerant Multi-Robot Cooperation

by Lynne E. Parker - IEEE Transactions on Robotics and Automation , 1998
"... ALLIANCE is a software architecture that fa- cilitates the fault tolerant cooperative control of teams of heterogeneous mobile robots performing missions composed of loosely coupled subtasks that may have ordering dependencies. ALLIANCE allows teams of robots, each of which possesses a variety of hi ..."
Abstract - Cited by 508 (13 self) - Add to MetaCart
architecture allows the robot team members to respond robustly, reliably, flexibly, and coherently to unexpected environmental changes and modifications in the robot team that may occur due to mechanical failure, the learning of new skills, or the addition or removal of robots from the team by human

The benefits of being present: Mindfulness and its role in psychological well-being

by Kirk Warren Brown, Richard M. Ryan - Journal of Personality & Social Psychology , 2003
"... Mindfulness is an attribute of consciousness long believed to promote well-being. This research provides a theoretical and empirical examination of the role of mindfulness in psychological well-being. The development and psychometric properties of the dispositional Mindful Attention Awareness Scale ..."

selfawareness. An experience-sampling study shows that both dispositional and state mindfulness predict self-regulated behavior and positive emotional states. Finally, a clinical intervention study with cancer patients demonstrates that increases in mindfulness over time relate to declines in mood disturbance

Cortical surface-based analysis. I. Segmentation and surface reconstruction

by Anders M. Dale, Bruce Fischl, Martin I. Sereno - Neuroimage , 1999
"... Several properties of the cerebral cortex, including its columnar and laminar organization, as well as the topographic organization of cortical areas, can only be properly understood in the context of the intrinsic two-dimensional structure of the cortical surface. In order to study such cortical pr ..."

properties in humans, it is necessary to obtain an accurate and explicit representation of the cortical surface in individual subjects. Here we describe a set of automated procedures for obtaining accurate reconstructions of the cortical surface, which have been applied to data from more than 100 subjects

What good are positive emotions

by Barbara L. Fredrickson - Review of General Psychology , 1998
"... This article opens by noting that positive emotions do not fit existing models of emotions. Consequently, a new model is advanced to describe the form and function of a subset of positive emotions, including joy, interest, contentment, and love. This new model posits that these positive emotions ser ..."

Programs with Common Sense

by John McCarthy - Semantic Information Processing , 1968
"... This paper will discuss programs to manipulate in a suitable formal lan- guage (most likely a part of the predicate calculus) common instrumental statements. The basic program will draw immediate conclusions from a list of premises. These conclusions will be either declarative or imperative sentence ..."

These actions may include printing sentences, moving sentences on lists. and reinitiating the basic deduction process on these lists. Facilities will be provided for communication with humans in the system via manual

Policies to Foster Human Capital

by James J. Heckman, James J. Heckman, James J. Heckman - Research in Economics 54 , 2000
"... This paper considers the sources of skill formation in a modern economy and emphasizes the importance of both cognitive and noncognitive skills in producing economic and social success and the importance of both formal academic institutions and families and firms as sources of learning. Skill format ..."

Autograph: Toward automated, distributed worm signature detection

by Hyang-ah Kim - In Proceedings of the 13th Usenix Security Symposium , 2004
"... Today’s Internet intrusion detection systems (IDSes) monitor edge networks ’ DMZs to identify and/or filter malicious flows. While an IDS helps protect the hosts on its local edge network from compromise and denial of service, it cannot alone effectively intervene to halt and reverse the spreading o ..."

Generation of the worm signatures required by an IDS—the byte patterns sought in monitored traffic to identify worms—today entails non-trivial human labor, and thus significant delay: as network operators detect anomalous behavior, they communicate with one another and manually
