Supporting ontological analysis of taxonomic relationships (2001, methodology): “The taxonomy we have chosen makes intuitive sense prima facie, and in most cases the taxonomic pairs were taken from existing ontologies such as Wordnet [25], Pangloss [21], and CYC [22].”
Predication (2001, unknown): “Hand-coding word meanings, as in WordNet (Miller, 1996), or hand-coding a complete lexical knowledge base, as in the CYC project (Lenat & Guha, 1990), has been the traditional approach.”
Essentials of General Intelligence: The Direct Path to Artificial General Intelligence (2007, background): “Moving further away from embodied cognitive science to purely classical research in general intelligence, perhaps the best known system is the Cyc project being pursued by [19].”
Overview and analysis of methodologies for building ontologies (2002, background): “The phases for building the Cyc ontology are (Lenat et al ., 1990) given below (see also Figure 1): • The ﬁrst phase proposes manually coding the explicit and implicit knowledge appearing in the knowledge sources without the help of natural language and learning systems.”
Computing Semantic Relatedness Using Wikipedia-based Explicit Semantic Analysis (2007, background): “It has long been recognized that in order to process natural language, computers require access to vast amounts of common-sense and domain-specific world knowledge [Buchanan and Feigenbaum, 1982; Lenat and Guha, 1990].”
Ontology Matching (2007, methodology): “Examples are the upper Cyc ontology (Lenat and Guha 1990), the Suggested Upper Merged Ontology (SUMO) (Niles and Pease 2001), the Unified Foundational Ontology (UFO) (Guizzardi 2005), and Descriptive Ontology for Linguistic and Cognitive Engineering (DOLCE) (Gangemi et al.”
Word Sense Disambiguation: The State of the Art (2005, background): “In the mid-1980's, several efforts began to construct large-scale knowledge bases by hand (for example, WordNet (Miller et al., 1990; Fellbaum, forthcoming-a), CyC (Lenat and Guha, 1990), ACQUILEX (Briscoe, 1991), COMLEX (Grishman et al., 1994; Macleod et al., forthcoming), etc.”
Dynamic Ontologies on the Web (2000, background): “As is common in many ontology efforts, such as Ontolingua (Farquhar, Fikes, and Rice 1997) or Cyc (Lenat and Guha 1990), SHOE ontologies build on or extend other ontologies, forming a lattice with the most general ontologies at the top and the more specific ones at the bottom.”
