In the work here presented, we apply textual and sequential methods to assess the outcomes of an unconstrained multiparty dialogue. In the context of chat transcripts from a collaborative learning scenario, we demonstrate that while low-level textual features can indeed predict student success, models derived from sequential discourse act labels are also predictive, both on their own and as a s...

Detection of discourse structure is crucial in many text-based applications. This paper presents an original framework for describing textual parallelism which allows us to generalize various discourse phenomena and to propose a unique method to recognize them. With this prospect, we discuss several methods in order to identify the most appropriate one for the problem, and evaluate them based o...

We study the relationship between the structure of" discourse and a set of summarization heuristics that are employed by current systems. A tight coupling of the two enables us to learn genre-specific combinations of heuristics that can be used for disambiguation during discourse parsing. The same coupling enables us to construct discourse structures that yield summaries that contain textual un...

Social media provides a unique platform enabling public discourse around cross-cutting ideologies. In this paper, we provide a methodological lens for studying the discourses around the controversial topic of abortion on social media. Drawing from the theoretical framework of “Critical Discourse Analysis”, we study discourse around abortion on Twitter through analysis of language and the manife...

We present the Prague Discourse Treebank 1.0, a collection of Czech texts annotated for various discourse-related phenomena "beyond the sentence boundary". The treebank contains manual annotations of (1), discourse connectives, their arguments and senses, (2), textual coreference, and (3), bridging anaphora, all carried out on 50k sentences of the treebank. Contrary to most similar projects, th...

In any discourse domain, certain chunks are particularly frequent and deserve attention by the novice to be initiated and by the expert to maintain a sense of community. To make a relevant contribution to the awareness about applied linguistics texts and discourse, this study attempted to develop lists of lexical chunks frequently used in the abstracts of applied linguistics journals. The abstr...

We describe ongoing work in semi-automatic annotating corpus, with the goal to answer “why” question in question answering system and give a construction of the coherent tree for text summarization. In this paper we present annotation schemas for identifying the discourse relations that hold between the parts of text as well as the particular textual of span that are related via the discourse r...

The present study aims at proving that yalla ‘hurry’ is a discourse marker in Jordanian Spoken Arabic (henceforth, JSA). It also investigates the textual functions of different contexts. data consisted 104 scenarios, including JSA yalla. researchers relied mainly on observation to collect needed for study. A panel four raters, who were professors linguistics, tested validity data. Moreover, gro...
