The present research addressed the prosodic realization of global and local text structure and content in the spoken discourse data produced by Persian EFL learners. Two newspaper articles were analyzed using Rhetorical Structure Theory. Based on these analyses, the global structure in terms of hierarchical level, the local structure in terms of the relative importance of text segments and the ...

in this work, sio2 –zro2 mixed oxides was prepared by the polymeric sol–gel route. the characterization of pore structure, which determines the permeation process of membrane, is of great importance. so far, most investigations have focused on such pore structure as specific surface area and pore size distribution, but the surface fractal, the important parameter reflecting the roughness of por...

Technical documentation such as user manual and manufacturing document is now an important part of the industrial production. Indeed, without such documents, the products can neither be manufactured nor used according to their complexity. Therefore, the increasing volume of such documents stored in the electronic format, needs an automatic classification system in order to categorize them in pr...

XML repositories are usually queried both on structure and content. Due to structural heterogeneity of XML, queries are often interpreted approximately and their answers are returned ranked by scores. Computing answer scores in XML is an active area of research that oscillates between pure content scoring such as the wellknown tf*idf and taking structure into account. However, none of the exist...

The outer regions of galaxies are expected to contain important clues about the way in which galaxies are assembled. Although quantitative study of these parts has been severely limited in the past, breakthroughs are now being made thanks to the combination of wide-area star counts, deep HST imagery and 8-m class spectroscopy. I review here several recent results concerning substructure, star c...

This paper describes experiments on cleaning web corpora. While previously described approaches focus mainly on the visual representation of web pages, we evaluate approaches that rely on content and structure. We have evaluated a heuristics-based approach, as well as approaches based on decision trees, a genetic algorithm and language models. The best performance was achieved using the heurist...
