Analyzing Clusters and Constellations from Untwisting shortened links on Twitter using Conceptual Graphs
TL;DR: This paper describes a case study in which conceptual graphs were used to underpin an exploration of a corpus of tweets relating to the Transportation Security Administration, and demonstrates the emerging model built up of the data landscape involved and of the business structures that underlie the technical frameworks relied upon by microblogging software.
Journal ArticleDOI
Temporal, spatial, and constraint handling in the Conceptual Programming environment, CP
TL;DR: A model of logic synthesis that uses technology-specific design rules and extends rule-based search to functional decomposition and technology mapping is presented, which improves design quality by taking advantage of the target technology but is not robust to technology changes.
Book ChapterDOI
Games of inquiry for collaborative concept structuring
Mary Keeler,Heather D. Pfeiffer +1 more
TL;DR: It is suggested that games of inquiry can be developed to formalize user collaboration and technology needs, for improved specification of tool requirements in the testbed context.
The effect of data structures modifications on algorithms for reasoning operations using a conceptual graphs knowledge base
TL;DR: It is believed that changing the reasoning operation's algorithm and providing adequate data structures for them can improve the implementation of the operation for use in intelligent systems; therefore, making them faster and more efficient.
Book ChapterDOI
Building a pragmatic methodology for KR tool research and development
Mary Keeler,Heather D. Pfeiffer +1 more
TL;DR: It is claimed that methodological theory suggests a prag-matic method for KR research and tool advancement in the form of an open-ended game somewhat like a child's game of building blocks, in which the forms of the "blocks" would be propositional rather than physical, with conditional propositions establishing the "dimensions," in place of the physical dimensions of blocks.
