Analogy is heavily used in instructional texts. We introduce the concept of analogical dialogue acts (ADAs), which represent the roles utterances play in instructional analogies. We describe a catalog of such acts, based on ideas from structure-mapping theory. We focus on the operations that these acts lead to while understanding instructional texts, using(More)
Word sense disambiguation is an important problem in learning by reading. This paper introduces analogical word-sense disambiguation, which uses human-like analogical processing over structured, relational representations to perform word sense disambiguation. Cases are automatically constructed using representations produced via natural language analysis of(More)
One challenge faced by cognitive systems is how to organize information that is learned by reading. Analogical reasoning provides a method for immediately using learned knowledge, and analogical generalization potentially provides a means to integrate knowledge across multiple sources. To use analogy requires organizing information into effective cases.(More)
One of the original motivations for qualitative reasoning was to capture the informal, intuitive notions about the continuous world that we all share, learned via a combination of experience and culture. For example, prior research suggests that qualitative dynamics can play an important role in natural language semantics. However, the constraints of(More)
