“…The most crucial task in signaling annotation is the selection of signal types. The taxonomy of discourse signals used in this project is adapted from that of Das and Taboada (2017), with additional types and subtypes to better suit other genres. Two new types and four new subtypes of the existing types are proposed: the two new types are Visual and Textual in which the subtype of the former is Image and the subtypes of the latter are Title, Date, and Attribution.…”

Recent research on discourse relations has found that they are cued not only by discourse markers (DMs) but also by other textual signals and that signaling information is indicative of genres. While several corpora exist with discourse relation signaling information such as the Penn Discourse Treebank (PDTB, Prasad et al. 2008) and the Rhetorical Structure Theory Signalling Corpus (RST-SC, Das and Taboada 2018), they both annotate the Wall Street Journal (WSJ) section of the Penn Treebank (PTB, Marcus et al. 1993), which is limited to the news domain. Thus, this paper adapts the signal identification and anchoring scheme to three more genres, examines the distribution of signaling devices across relations and genres, and provides a taxonomy of indicative signals found in this dataset.

“…Rhetorical Structure Theory (RST, Mann and Thompson 1988) is a well-known theoretical framework that extensively investigates discourse relations and is adopted by Das and Taboada (2017) and the present study. RST is a functional theory of text organization that identifies hierarchical structure in text.…”

“…DMs are widely believed to be the most reliable signals of coherence relations. Accordingly, their role in discourse interpretation has been extensively studied both in (psycholinguistic) discourse processing (see Das [2014] for an overview) and computational discourse applications such as discourse parsing (Hernault et al, 2010;Lin et al, 2014), machine translation (Meyer et al, 2011), text summarization (Alonso i Alemany, 2005), or argumentation mining (Kirschner et al, 2015).

The RST Signalling Corpus (Das et al, 2015) Furthermore, it has also been shown that on a great many occasions relations can simultaneously be indicated by multiple signals (Das, 2014;Das & Taboada, 2018b). In Example [7] from the RST Signalling Corpus (Das et al, 2015), the Circumstance relation between the text segments is signalled by three signals: (i) the DM "since", (ii) the change of tense between two clauses (simple past → present perfect), and (iii) an indicative phrase ("last December").…”

In this paper, we investigate the signalling of coherence relations when they are simultaneously indicated by more than one signal. In particular, we examine the co-occurrence of discourse markers and other relational signals when they are used together to mark a single relation. With the goal to identify the source of the usage of multiple signals, we postulate a twofold hypothesis: the co-occurrence of discourse markers and other textual signals can result from the type of the discourse markers themselves, or it can be triggered by the semantics of the relations in question. We conduct a corpus study, examining instances of multiple signals (co-occurrence of discourse markers and other signals) in the RST Signalling Corpus (Das et al., 2015). We analyze discourse markers that appear as part of multiple signals and also relations that frequently employ multiple signals as their indicators. Our observations suggest that the signalling of relations by multiple signals is a complex phenomenon, since the co-occurrence of discourse markers and other textual signals appears to arise from multiple sources.

“…Dada la relevancia de estas relaciones, su indagación ostenta un lugar privilegiado tanto en los estudios del discurso como en aquellos psicolingüísticos centrados en la comprensión. En cuanto a los primeros, existe una extensa investigación en torno a sus tipos y cantidad (Grosz y Sidner, 1986;Mann y Thompson, 1988;Sanders, et al, 1992;Renkema, 2009;Da Cunha, Torres-Moreno & Sierra, 2011;Ibáñez, Moncada, y Santana, 2015) a nuevas metodologías para su anotación (Taboada y Das, 2013;Hoek, Evers-Vermeul, y Sanders, 2017;Scholman, Evers-Vermeul, y Sanders, 2016) y a los marcadores discursivos que las explicitan (Duque, 2014;2016;Santana, Nieuwenhuijsen, Spooren y Sanders, 2017;Taboada & Das, 2013;Das y Taboada, 2017;Taboada y Gómez-González, 2012).…”

Resumen. El presente estudio tuvo por objetivo determinar el efecto de los conectores en la eficiencia del procesamiento de relaciones de coherencia causal en lectores con diversos grados de conocimiento previo. Se implementó un experimento con estudiantes universitarios de una misma área disciplinar utilizando el paradigma de lectura autocontrolada con ventana cumulativa y combinando mediciones en línea (tiempos de lectura) y fuera de línea (precisión en una tarea de verificación). Para controlar su grado de conocimiento previo, los participantes fueron agrupados según el paradigma Experto-Novato dependiendo del año de estudios en el que se encontraban. Nuestros datos muestran, a nivel general, que, pese a que los conectores causales incrementan los tiempos de lectura, facilitan una comprensión más profunda. En cuanto a la comparación entre grupos, si bien nuestros datos no muestran diferencias entre ellos, revelan el mismo patrón general. Estos datos sugieren que, al menos en entornos especializados, los conectores desencadenan una lectura intencionada, lo que en el caso de lectores con alto grado de conocimiento disciplinar, como los de nuestro estudio, involucra que los recursos cognitivos son utilizados para asegurar una comprensión profunda. Asimismo, nuestros datos sugieren que una lectura más veloz, no necesariamente asegura la construcción de una representación mental coherente. Palabras clave: Conectores, relaciones de coherencia, coherencia causal, conocimiento previo [en] Interaction between connectives and previous knowledge in the processing of causal coherence Abstract. The current study aimed at determining the effect of connectives on low and high knowledge readers' processing efficiency of causal coherence relations. To achieve this goal, we carried out an experiment with college students from the same program using the self-paced reading paradigm with cumulative windows and combing online (reading times) and offline measures (accuracy in a verification task). To control their previous knowledge, participants were grouped based on the Novice-Expert paradigm (first and fifth year, respectively). Our data show, in a general level, that although causal connectives trigger higher reading times they facilitate a deeper comprehension. Regarding the comparison across groups, although our data do not show differences between Novice and Experts, they reveal the same general pattern. These findings suggest that, at least in highly specialized contexts, connectives trigger a planned reading, which involve that high-knowledge students (like ours) use their cognitive resources to ensure a deeper comprehension. Likewise, our data suggest that faster reading does not necessarily translate into the construction of a coherent mental representation.
