SemEval-2016 task 5 : aspect based sentiment analysis
International audienceThis paper describes the SemEval 2016 shared task on Aspect Based Sentiment Analysis (ABSA), a continuation of the respective tasks of 2014 and 2015. In its third year, the task provided 19 training and 20 testing datasets for 8 languages and 7 domains, as well as a common evaluation procedure. From these datasets, 25 were for sentence-level and 14 for text-level ABSA; the latter was introduced for the first time as a subtask in SemEval. The task attracted 245 submissions from 29 teams
Computational Sociolinguistics: A Survey
Language is a social phenomenon and variation is inherent to its social
nature. Recently, there has been a surge of interest within the computational
linguistics (CL) community in the social dimension of language. In this article
we present a survey of the emerging field of "Computational Sociolinguistics"
that reflects this increased interest. We aim to provide a comprehensive
overview of CL research on sociolinguistic themes, featuring topics such as the
relation between language and social identity, language use in social
interaction and multilingual communication. Moreover, we demonstrate the
potential for synergy between the research communities involved, by showing how
the large-scale data-driven methods that are widely used in CL can complement
existing sociolinguistic studies, and how sociolinguistics can inform and
challenge the methods and assumptions employed in CL studies. We hope to convey
the possible benefits of a closer collaboration between the two communities and
conclude with a discussion of open challenges.Comment: To appear in Computational Linguistics. Accepted for publication:

Language contact and language decay. Socio-political and linguistic perspectives
The present linguistic situation in Malta is a reflection of historical and political
permutations of the past. The simultaneous presence of two languages in Malta –
generally described as a bilingual situation, but which in fact includes a number of
features which can be defined more appropriately through diglossia – gives rise to a
context wherein language contact is extremely frequent: this occurs through both
inter- and intrasentential code-switching as well as through the constant integration of
foreign terms, mainly from Italian and English, into Maltese. Language policies in Malta are frequently caught in the midst of these dynamic diachronic and synchronic linguistic processes and often operate on two fronts: on the one hand internal changes inherent to the Maltese language must be taken into
consideration, on the other hand language use, characterized by the presence of both
English and Maltese, also must be accounted for.peer-reviewe
Sentiment Analysis in Digital Spaces: An Overview of Reviews
Sentiment analysis (SA) is commonly applied to digital textual data,
revealing insight into opinions and feelings. Many systematic reviews have
summarized existing work, but often overlook discussions of validity and
scientific practices. Here, we present an overview of reviews, synthesizing 38
systematic reviews, containing 2,275 primary studies. We devise a bespoke
quality assessment framework designed to assess the rigor and quality of
systematic review methodologies and reporting standards. Our findings show
diverse applications and methods, limited reporting rigor, and challenges over
time. We discuss how future research and practitioners can address these issues
and highlight their importance across numerous applications.Comment: 44 pages, 4 figures, 6 tables, 3 appendice
