Tear-Insert-Fold grammars

Content Provider ACM Digital Library
Author Scott, Elizabeth Johnstone, Adrian
Abstract Context Free Grammars (CFGs) are simple and powerful formalisms for defining languages (sets of strings) whose semantics are specified hierarchically --- the meaning of a string is determined by terminals and the meanings of substrings. This hierarchy is captured in the derivation tree corresponding to the string. Derivation trees usually contain more structure than is strictly required to determine the semantics of the string so in practice a simplified or abstract syntax tree is used as an internal representation of a concrete text. Indeed, much of the work of a compiler or source-source translator may be described in terms of stepwise transformation of such trees, culminating in a final traversal during which the translated text is output. This paper introduces Tear-Insert-Fold grammars which add tree-manipulation annotations to standard CFGs. These annotations allow typical abstract forms to be constructed directly from the grammar for the concrete syntax and provide a convenient and concise specification of the relationship between the set of derivation trees and the set of abstract trees for a parser. More significantly, for any TIF grammar $Γ_{0}$ there is a TIF grammar $Γ_{1}$ whose derivation trees are the abstract trees produced by $Γ_{0}.$

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
