Towards a Theory of Discourse Processing | Flashback Sequences Described by D-trees
نویسنده
چکیده
This paper is concerned with an approach to discourse processing via a new more general interpretation of Tree Adjoining Grammars (TAG) proposed by Vijay-Shanker (1992). This formalism is based on so-called Description trees (D-trees) (Marcus et al. 1983, Back-ofen 1995). I will discuss a discourse phenomenon commonly used as a stylistic device, namely ashback sequences. These sequences are particularly interesting, since they contradict the naively assumed pre-supposition that everything has to be described in the order in which it happened. My approach is based on a Tree Description Grammar (TDG) using D-trees for the rhetorical relations (e.g. narration, elaboration and ashback) which hold between the discourse segments. This TDG allows us to model a exible discourse structure which can account for a wide range of diicult to explain discourse eeects including ashback sequences. This discourse grammar allows the discourse structure to be reened simply by adding further information.

Nowadays, the clustering of proteins and enzymes in particular, are one of the most popular topics in bioinformatics. Increasing number of chitinase genes from different organisms and their sequences have beenidentified. So far, various mathematical algorithms for the clustering of chitinase genes have been used butmost of them seem to be confusing and sometimes insufficient. In the...
متن کاملParallel Generation of t-ary Trees
A parallel algorithm for generating t-ary tree sequences in reverse B-order is presented. The algorithm generates t-ary trees by 0-1 sequences, and each 0-1 sequences is generated in constant average time O(1). The algorithm is executed on a CREW SM SIMD model, and is adaptive and cost-optimal. Prior to the discussion of the parallel algorithm a new sequential generation with O(1) average time ...
متن کاملA New Approach to Public Policy Studies Relying on the Theory of Critical Discourse Analysis Studies the State as a Discourse
Understanding the policy cycle, as well as scrutinizing the text of hidden and obvious policies and rules, requires a model of discourse analysis based on which discursive ap-proaches of policy makers are understood and estimated. However, when it comes to presenting a policy model, we have to use the views of policy theorists to see how a problem as a "public goods" can be found in the policy ...
متن کاملIncorporating Punctuation Into the Sentence Grammar: A Lexicalized Tree Adjoining Grammar Perspective
Punctuation helps us to structure, and thus to understand, texts. Many uses of punctuation straddle the line between syntax and discourse, because they serve to combine multiple propositions within a single orthographic sentence. They allow us to insert discourse-level relations at the level of a single sentence. Just as people make use of information from punctuation in processing what they re...
