Research related to online discussions frequently faces the problem of analyzing huge corpora. Natural Language Processing (NLP) technologies may allow automating this analysis. However, the state-of-the-art in machine learning and text mining approaches yields models that do not transfer well between corpora related to different topics. Also,…

This paper reports on the development of a prototype tool which shows how learners can be helped to reflect upon the accuracy of their writing. Analysis of samples of freely written texts by intermediate and advanced learners of English as a foreign language (EFL) showed evidence of weakness in the use of tense and aspect. Computational discourse…

While many may disparage the online website Rate my Professor, it remains a popular public evaluation site for students to post their evaluations and commentary on their professors. What implications can be drawn about students' perceptions of instruction and what are the implications of students' perceptions for professors and their work? Using…

Numerous studies have affirmed the value of asynchronous online communication as a learning resource. Several investigations, however, have indicated that discussions in asynchronous environments are often neither interactive nor coherent. The research reported sought to develop an enhanced understanding of interactional coherence, argumentation,…

Corpus-based instruction, also referred to as corpus-based linguistics, is essentially the study of genre texts for the production of materials that fit a specific group of second language learners. For example, if a group of students is learning the language in order to read medical articles, a specific teaching program can be set up based on the…

Consisting of two separate papers, "Representational Issues in Systemic Functional Grammar," by Christian Matthiessen and "Systemic Grammar and Functional Unification Grammar," by Robert Kasper, this document deals with systemic aspects of natural language processing and linguistic theory and with computational applications of…
