In accordance with the compositionality criterion and hierarchy principle of Rhetorical Structure Theory, this study reframes each tree in the RST Discourse Treebank into three new dependency trees with ultimate nodes being clauses, sentences, and paragraphs, respectively, which also draw on an analogy between syntactic and discourse trees. Detailed percentages of various RST relations at the three granularity levels are examined, illuminating the discourse processes of organizing units of one granularity level into those of the next upper level and suggesting (...) certain homogeneity and interaction across levels in the Treebank, particularly at the two upper levels. The study demonstrates the applicability of RST analysis between same-level terminal units. With unique analytical advantages, the newly constructed discourse dependency trees provide new research prospects. (shrink)

In contrast to symbol-manipulation approaches, Cognitive Linguistics offers a modal rather than an amodal account of meaning in language. From this perspective, the meanings attached to linguistic expressions, in the form of conceptualisations, have various properties in common with visual forms of representation. This makes Cognitive Linguistics a potentially useful framework for identifying and analysing language-image relations in multimodal texts. In this paper, we investigate language-image relations with a specific focus on intersemiotic convergence. Analogous with research on gesture, we extend (...) the notion of co-text images and argue that images and language usages which are proximal to one another in a multimodal text can be expected to exhibit the same or consistent construals of the target scene. We outline some of the dimensions of conceptualisation along which intersemiotic convergence may be enacted in texts, including event-structure, viewpoint, distribution of attention and metaphor. We take as illustrative data photographs and their captions in online news texts covering a range of topics including immigration, political protests, and inter-state conflict. Our analysis suggests the utility of Cognitive Linguistics in allowing new potential sites of intersemiotic convergence to be identified and in proffering an account of language-image relations that is based in language cognition.
