Hypernymy relation acquisition has been widely investigated, especially because taxonomies, which often constitute the backbone structure of semantic resources are structured using this type of relations. Although lots of approaches have been dedicated to this task, most of them analyze only the written text. However relations between not necessarily contiguous textual units can be expressed, t...

Online user comments contain valuable user opinions. Comments vary greatly in quality and detecting high quality comments is a subtask of opinion mining and summarization research. Finding attentive comments that provide some reasoning is highly valuable in understanding the user’s opinion particularly in sociopolitical opinion mining and aids policy makers, social organizations or government s...

In this paper, we discuss different methods which use meta information and richer context that may accompany source language input to improve machine translation quality. We focus on category information of input text as meta information, but the proposed methods can be extended to all textual and non-textual meta information that might be available for the input text or automatically predicted...

Theories of discourse structure hypothesize a hierarchical structure of discourse segments, typically tree-structured. While substantial work has been done on identifying and automatically recognizing the textual and prosodic correlates of discourse structure in monologue, comparable cues for dialogue or multiparty conversation, and in particular humancomputer dialogue remain relatively less st...

Text analysis traditions in France and the United States include discourse analysis, critical linguistics, French functional linguistics, Bakhtinian dialogics, and “generous reading.” These frames have not been used, however, in crosscultural analysis of university student writing. The author presents a study of 250 student texts from French and U.S. introductory university courses, using a met...

The following main ideas have been pointed out and put to work within our paper: (a) Information Structure (IS) theories (topic-focus, theme-rheme, background-contrast, informational and contrastive focus, focus projection rules, etc.) on text are shown to behave currently as a consistent linguistic tool that can stand behind a correct, language and contextual-depending, mapping of text into sp...

[Context and motivation] Natural language is the main presentation means in industrial requirements documents. In such documents, system behavior is specified either in the form of scenarios or in the form of automata described in natural language. The behavior descriptions are often incomplete: For the authors of requirements documents some facts are so obvious that they forget to mention them...

Several studies have proposed meta-models for textual representations of use cases. Each of these meta-models has different goals and viewpoints, with either varying concepts and relationships or different semantics for the same concept. In Model-Driven Engineering approaches where there is no compatible proposal or a more appropriate viewpoint, or where there is no intention to limit the appro...

In this paper I propose that the principles of Emergent Grammar (Hopper 1987, 1998) can be applied to lexical semantics. I discuss three instances of discourse semantics to show why an emergent view of semantics can provide a realistic account of semantics in discourse. The three cases are: 1) emergence and negotiation of meaning due to participant interaction in discourse; 2) (re)distribution ...
