Conversational Machine Comprehension: a Literature Review

Conversational Machine Comprehension (CMC), a research track in conversational AI, expects the machine to understand an open-domain natural language text and thereafter engage in a multi-turn conversation to answer questions related to the text. While most of the research in Machine Reading Comprehension (MRC) revolves around single-turn question answering (QA), multi-turn CMC has recently gained prominence, thanks to the advancement in natural language understanding via neural language models such as BERT and the introduction of large-scale conversational datasets such as CoQA and QuAC. The rise in interest has, however, led to a flurry of concurrent publications, each with a different yet structurally similar modeling approach and an inconsistent view of the surrounding literature. With the volume of model submissions to conversational datasets increasing every year, there exists a need to consolidate the scattered knowledge in this domain to streamline future research. This literature review attempts at providing a holistic overview of CMC with an emphasis on the common trends across recently published models, specifically in their approach to tackling conversational history. The review synthesizes a generic framework for CMC models while highlighting the differences in recent approaches and intends to serve as a compendium of CMC for future researchers.Comment: Accepted to COLING 202

Beyond the literal meaning of words in children with klinefelter syndrome: two case studies

Literature on children with Klinefelter Syndrome (KS) points to general linguistic difficulties in both comprehension and production among other cognitive functions, and in the majority of cases, these coexist with an intellectual level within the norms. In these conditions, children having language delay generally engage in language therapy and are systematically monitored across ages. In this article, we present the profiles of two children with KS (47, XXY), aged 9.1 (Child S) and 13 (Child D), whose language development was assessed as adequate at age 3, and for this reason, did not receive any language treatment. At the present stage, their IQ, as measured by Wechsler Scales (Child S: 92; Child D: 101), is within the norm, but they both present marked weaknesses in pragmatic skills such as figurative language comprehension. The analysis of these two cases points to the need to go beyond global indexes of verbal abilities, as the same global index may mask a wide diversification of individual profiles. In addition, this study underlines the importance of monitoring the developmental trajectories of children like Child D and Child S, because weaknesses in pragmatic skills that are relevant for both academic achievement and social adaptation could emerge at later stages

A Review and Assessment of Technology and Materials For English Language Teaching and Learning

As an increasing number of materials and language learning resources have become available online, English language learners of any level can easily access an unlimited number of websites and applications at the swipe of a finger. For teachers and students concerned with the quality of these online tools, being directed to websites that are trustworthy and truly educational can become a daunting task. This two-part article aims to support teachers in this challenge. In Section One, titled Website Review and Assessment for Listening Instruction , the results of a review and assessment conducted to determine the quality of readily available online resources and study materials intended for English language teaching and learning are presented. In Section Two, titled Online English Language Course Assessment, a review and assessment of an online language course suitable for either self-study or for use within the context of the English as a Foreign Language (EFL) classroom will be presented

The Professional Learning Motivation Profile (PLMP): A Tool for Assessing Instructional Motivation

This article chronicles the collaboration of administrators from six districts and three college professors as they assessed professional learning during the first year of teaching. The examination led to the development of a Professional Learning Motivation Profile. Results from the profile indicated a traditional model of professional development was not effective in growing the professional learning motivation of beginning teachers. Anecdotal data shared includes how administrators used the data to inform conversations designed to support teachers in their journey toward courageous, effective instruction

Conversation therapy for agrammatism: exploring the therapeutic process of engagement and learning by a person with aphasia.

A recent systematic review of conversation training for communication partners of people with aphasia has shown that it is effective, and improves participation in conversation for people with chronic aphasia. Other research suggests that people with aphasia are better able to learn communication strategies in an environment which closely mirrors that of expected use, and that cognitive flexibility may be a better predictor of response to therapy than severity of language impairment. This study reports results for a single case, one of a case series evaluation of a programme of conversation training for agrammatism that directly involves a person with aphasia (PWA) as well as their communication partner. It explores how a PWA is able to engage with and learn from the therapy, and whether this leads to qualitative change in post-therapy conversation behaviours

Promoting Student Success: Bilingual Education Best Practices and Research Flaws

This paper first determines the benefits which bilingual education offers and then compares transitional, dual-language, and heritage language maintenance programs. After exploring the outcomes, contexts, and practical implications of the various bilingual programs, this paper explores the oversight in most bilingual studies, which assess students’ syntax and semantics while neglecting their understanding of pragmatics and discourse structures (Maxwell-Reid, 2011). Incorporating information from recent studies which question traditional understandings of bilingualism and argue that biliteracy requires more than grammatical and vocabulary instruction, this paper proposes modifications in current research strategies and suggests best practices for transitional, dual-language, and heritage maintenance programs
