Generalization for Explanation-Based Schema Acquisition
نویسنده
چکیده
This paper is about explanation-based learning for heuristic problem solvers which "build" solutions using schemata (frames like scripts) as both "bricks" and "mortar". The heart of the paper is a description of a generalization method which is designed to extract as much information as possible from examples of successful problem solving behavior. A' related generalizer, (less powerful but more efficient), has been implemented as part of an experimental apprentice.*

The Amphichronic Program vs. Evolutionary Phonology
Evolutionary Phonology. Evolutionary Phonology seeks to derive typological generalizations from recurrent patterns of language change, themselves assumed to be rooted in perception, production, and acquisition. The goal is to eliminate UG by providing diachronic explanations for the cross-linguistic evidence that has been used to motivate it. (2) shows a schema of this program, where the arrows...
متن کاملL2 Learners' Acquisition of English Nominal Clauses: Effects of Textual Enhancement, Metalinguistic Explanation, and Self-Regulation
This study aimed to investigate the impact of textual enhancement and metalinguistic explanation as focus-on-form tasks tending to encourage the acquisition of nominal clauses (NCs) in English. It explored (a) whether textual enhancement and metalinguistic explanation would promote and enhance the knowledge of NCs, (b) whether these two tasks would differ in terms of enhancing learners' knowled...
متن کاملRepresenting Generalization/Specialization in XML Schema
XML is an effective universal data-interchange format, and XML Schema has become the preeminent mechanism for describing valid XML document structures. Generalization/specialization and its constraints are fundamental concepts in system modeling and design, but are difficult to express and enforce with XML Schema. This mismatch leads to unnecessary complexity and uncertainty in XML-based models...
متن کاملOn the Development of Case Theory: Triumphs and Challenges
X-bar theory, introduced in Chomsky 1970, constituted a major step toward explanatory adequacy, dramatically limiting the range of possible phrase structure rules. As with most explanatory advances, the resulting theory encounters serious descriptive problems. In the present instance, the major virtue of X-bar theory-the generalization of the phrase structure schema-immediately encountered empi...
متن کاملErratum to "Map generalization and schema transformation of geospatial data combined in a Web Service context [Computers, Environment and Urban Systems 34 (2010) 79-88]
The integration of multiple geodata sets is a major challenge for developing Spatial Data Infrastructures (SDIs). Currently, this integration is achieved using schema transformation processes. However, as SDIs mature and the need for more complex transformation processes increases, generalization provides appropriate tools for supporting complex transformations for the integration of different ...
