A recent EMC-sponsored MeriTalk survey1, involving over 150 federal agency video surveillance experts and leaders, reports that 99% of federal agencies believe video surveillance technology will improve their agency’s operations and ability to prevent crime, theft, and terrorism over the next five years. The survey also reveals that 79% believe their agency needs to improve collaboration betwee...

The paper proposed a new syntactic annotation scheme --functional chunk, which tried to represent information about grammatical relations between sentence-level predicates and their arguments. Under this scheme, we built a Chinese chunk bank with about two million Chinese characters, and developed some learned models for automatically annotating fresh text with functional chunks. We also propos...

Chunking, an experience based-learning mechanism, improves Soar's performance a great deal when viewed in terms of the number of subproblems required and the number of steps within a subproblem. This high-level view of the impact of chunking on performance is based on an deal computational model, which says that the time per step is constant. However, if the chunks created by chunking are expen...

Chess experts store domain-specific representations in their long-term memory; due to the activation of such representations, they perform with high accuracy in tasks that require the maintenance of previously seen information. Chunk-based theories of expertise (chunking theory: Chase & Simon, 1973; template theory: Gobet & Simon, 1996) state that expertise is acquired mainly by the acquisition...

Story statements cluster into episodes, so we expected the memory representations of statements to cluster into separate episode chunks in memory. Experiment 1 confirmed this chunking idea by showing that the recall of episode actions depends on the length of that episode, but not on the lengths of other episodes. Specifically, adding more actions to an episode increased recall of the original ...

In Situational Method Engineering, the concepts of both fragment and chunk have been proposed as the atomic element. These are examined here in terms of their conceptual integrity and in terms of how they may be used in method construction, drawing parallels to show that the similarities are more than the differences. The new ISO/IEC 24744 standard metamodel is used as a conceptual framework to...

Most new materials are introduced by selectively comparing their properties against those of steels. Steels set this standard because iron and its alloys have so much potential that new concepts are discovered and implemented with notorious regularity. In this 52nd Hatfield Memorial Lecture, I describe a remarkably beautiful microstructure consisting of slender crystals of ferrite, whose contro...

The present study adapted a paradigm used in visual perception by Biederman, Glass, and Stacy (1973) and analyzed the in ̄ uence of a coherent global context on the detection and recognition of musical target excerpts. Global coherence was modi® ed by segmenting minuets into chunks of four, two, or one bar. These chunks were either reordered (Experiments 1, 3, 4, 5) or transposed to different ke...

After reviewing the relevant theory on chess expertise, this paper re-examines experimentally the finding of Chase and Simon (1973a) that the differences in ability of chess players at different skill levels to copy and to recall positions are attributable to the experts' storage of thousands of chunks (patterned clusters of pieces) in long-term memory. Despite important differences in the expe...

The Termolator is a high-performing terminology extraction system, which will soon be available as open source software. The Termolator combines several different approaches to get superior coverage and accuracy. The system identifies potential instances of terminology using a chunking procedure, similar to noun group chunking, but favoring chunks that contain out-of-vocabulary words, nominaliz...
