title = {Towards a Big Data View on South Asian Linguistic Diversity},
abstract = {South Asia with its rich and diverse linguistic tapestry of hundreds of languages, including many from four major language families, and a long history of intensive language contact, provides rich empirical data for studies of linguistic genealogy, linguistic typology, and language contact. South Asia is often referred to as a linguistic area, a region where, due to close contact and widespread multilingualism, languages have influenced one another to the extent that both related and unrelated languages are more similar on many linguistic levels than we would expect. However, with some rare exceptions, most studies are largely impressionistic, drawing examples from a few languages. In this paper we present our ongoing work aiming at turning the linguistic material available in Grierson’s Linguistic Survey of India (LSI) into a digital language resource, a database suitable for a broad array of linguistic investigations of the languages of South Asia. In addition to this, we aim to contribute to the methodological development of large-scale comparative linguistics drawing on digital language resources, by exploring NLP techniques for extracting linguistic information from free-text language descriptions of the kind found in the LSI.},

title = {How can big data help us study rhetorical history?},
abstract = {Rhetorical history is traditionally studied through rhetorical treatises or selected rhetorical practices, for example the speeches of major orators. Although valuable sources, these do not give us the answers to all our questions. Indeed, focus on a few canonical works or the major historical key figures might even lead us to reproduce cultural self-identifications and false generalizations. However, thanks to increasing availability of relevant digitized texts, we are now at a point where it is possible to see how new research questions can be formulated – and how old research questions can be addressed from a new angle or established results verified – on the basis of exhaustive collections of data, rather than small samples, but where a methodology has not yet established itself. The aim of this paper is twofold: (1) We wish to demonstrate the usefulness of large-scale corpus studies (“text mining”) in the field of rhetorical history, and hopefully point to some interesting research problems and how they can be analyzed using “big-data” methods. (2) In doing this, we also aim to make a contribution to method development in e-science for the humanities and social sciences, and in particular in the framework of CLARIN. },

VTeX, with two aligned versions of the same text – before and after editing – and covers a variety of textual infelicities that proofreaders have edited. While previous shared tasks focused solely on grammatical errors (Dale and Kilgarriff, 2011; Dale et al., 2012; Ng et al., 2013; Ng et al., 2014), this time edits cover other types of linguistic misfits as well, including those that almost certainly could be interpreted as style issues and similar “matters of opinion”. The latter arise because of different language editing traditions, experience,
and the absence of uniform agreement on what “good” scientific language should look like. Initiating this task, we expected the participating teams to help identify the characteristics of “good” scientific language, and help create a consensus of which language improvements are acceptable (or necessary). Six participating teams took on the challenge.},

compare different domain adaptation techniques and find that a weighted combination of the two

improve classification when in-domain data with annotated proficiency levels is not available.},

The resource is based on a corpus of coursebook texts, and thus describes receptive vocabulary learners are exposed to during reading activities, as opposed to productive vocabulary they use when speaking or writing. The paper describes the methodology applied to create the list and to estimate the frequency distribution. It also discusses some chracteristics of the resulting resource and compares it to other lexical resources for Swedish. An interesting feature of this resource is the possibility to separate the wheat from the chaff, identifying the core vocabulary at each level, i.e. vocabulary shared by several coursebook writers at each level, from peripheral vocabulary which
is used by the minority of the coursebook writers.},

Our theorem provers use the technique theory exploration, which is a method to systematically discover interesting conclusions about a mathematical theory. We use the existing theory exploration system QuickSpec which conjectures properties for a program that seem to hold based on testing. The idea is to try to prove these explored conjectures together with the user-stated goal conjecture. By using this idea and connecting it with our previous work on Hip, the Haskell Inductive Prover, we were able to take new leaps in field of inductive theorem proving.
Additionally, we have developed a benchmark suite named TIP, short for Tons of Inductive Problems, with benchmark problems for inductive theorem provers, and a tool box for converting and manipulating problems expressed in the TIP format. There were two main reasons to this initiative. Firstly, the inductive theorem proving field lacked a shared benchmark suite as well as a format. Secondly, the benchmarks that have been used were outdated: all contemporary provers would solve almost every problem. We have so far added hundreds of new challenges to the TIP suite to encourage further research.

title = {From Distributions to Labels: A Lexical Proficiency Analysis using Learner Corpora},
abstract = {In this work we look at how information from second language learner essay corpora can be used for the evaluation of unseen learner essays. Using a corpus of learner essays which have been graded by well-trained human assessors using the CEFR scale, we extract a list of word distributions over CEFR levels. For the analysis of unseen essays, we want to map each word to a so-called target CEFR level using this word list. However, the task of mapping from a distribution to a single label is not trivial. We are also investigating how we can evaluate the mapping from distribution to label. We show that the distributional profile of words from the essays, informed with the essays’ levels, consistently overlaps with our frequency-based method, in the sense that words holding the same level of proficiency as predicted by our mapping tend to cluster together in a semantic space. In the absence of a gold standard, this information can be useful to see how often a word is associated with the same level in two different models. Also, in this case we have a similarity measure that can show which words are more central to a given level and which words are more peripheral.

title = {Seeking an Anchorage. Stability and Variability in Tonal Alignment of Rising Prenuclear Pitch Accents in Cypriot Greek},
abstract = {Although tonal alignment constitutes a quintessential property of pitch accents, its exact characteristics remain unclear. This study, by exploring the timing of the Cypriot Greek L*+H prenuclear pitch accent, examines the predictions of three hypotheses about tonal alignment: the invariance hypothesis, the segmental anchoring hypothesis, and the segmental anchorage hypothesis. The study reports on two experiments: the first of which manipulates the syllable patterns of the stressed syllable, and the second of which modifies the distance of the L*+H from the following pitch accent. The findings on the alignment of the low tone (L) are illustrative of the segmental anchoring hypothesis predictions: the L persistently aligns inside the onset consonant, a few milliseconds before the stressed vowel. However, the findings on the alignment of the high tone (H) are both intriguing and unexpected: the alignment of the H depends on the number of unstressed syllables that follow the prenuclear pitch accent. The ‘wandering’ of the H over multiple syllables is extremely rare among languages, and casts doubt on the invariance hypothesis and the segmental anchoring hypothesis, as well as indicating the need for a modified version of the segmental anchorage hypothesis. To address the alignment of the H, we suggest that it aligns within a segmental anchorage–the area that follows the prenuclear pitch accent–in such a way as to protect the paradigmatic contrast between the L*+H prenuclear pitch accent and the L+H* nuclear pitch accent.},

abstract = {Corpora and web texts can become a rich language learning resource if we have a means of assessing whether they are linguistically appropriate for learners at a given proficiency level. In this paper, we aim at addressing this issue by presenting the first approach for predicting linguistic complexity for Swedish second language learning material on a 5-point scale. After showing that the traditional Swedish readability measure, Läsbarhetsindex (LIX), is not suitable for this task, we propose a supervised machine learning model, based on a range of linguistic features, that can reliably classify texts according to their difficulty level.Our model obtained an accuracy of 81.3% and an F-score of 0.8, which is comparable to the state of the art in English and is considerably higher than previously reported results for other languages. We further studied the utility of our features with single sentences instead of full texts since sentences are a common linguistic unit in language learning exercises. We trained a separate model on sentence-level data with five classes, which yielded 63.4% accuracy. Although this is lower than the document level performance, we achieved an adjacent accuracy of 92%. Furthermore, we found that using a combination of different features, compared to using lexical features alone, resulted in 7% improvement in classification accuracy at the sentence level, whereas at the document level, lexical features were more dominant. Our models are intended for use in a freely accessible web-based language learning platform for the automatic generation of exercises, and they will be available also in the form of web-services.},

Each lexical item on the list is connected to its frequency distribution over the six levels of proficiency defined by the Common European Framework of Reference (CEFR) (Council of Europe, 2001}. To make this list a more reliable resource, we experiment with normalizing L2 word-level errors by replacing them with their correct equivalents.

title = {Huvudansatser för parsningsmetoder. Om programutvecklingens förutsättningar i en svensk kontext},
abstract = {Syftet med denna text var att ge en inblick i området (syntaktisk) parsning. Tanken
var att ge en bild av utvecklingen som var 1) fri från alltför tekniska detaljer, då
området är programmeringstekniskt, och 2) beskriven ur ett svenskt perspektiv.
Bakgrunden till valet av ämne till texten, som var tänkt att finnas med i antologin
Text och kontext, var att parsning är relativt okänt för många personer verksamma
inom närliggande områden, samtidigt som det är ett absolut nyckelbegrepp för
den som ägnar sig åt datorlingvistik eller språkteknologi.
Målet var alltså att ge en ganska allmän utifrånblick på några centrala sidor av
utvecklingen, samtidigt som det tydligt är så att den som själv arbetat med
utveckling kan ha starka åsikter och preferenser rörande metodval, något som i
ärlighetens namn kanske inte heller denna text är lösgjord från.
Hur ska det göras? Konsten att utveckla automatisk syntaxanalys av naturlig text
kan läras ut från ett flertal perspektiv. Det kan t.ex. ske med fokus på användandet
av en viss grammatikformalism, med fokus på beräkningssnabbhet, med fokus på
entydiggörande av möjliga ambiguiteter. Tolkningsval kan göras med hjälp av
antingen handskrivna regler eller inhämtad statistik.
En sorts huvudtema i denna text är hur metoder för parsning på senare år uppvisar
förändringar som kanske kan förklaras med att programmen har fått andra
användningsområden och att metoderna har anpassats därefter (en annan tolkning
är att flera senare system inte längre gör parsning i strikt mening).
När detta tänkta ”kapitel” var färdigt fick det kommentaren att det inte var
anpassat för antologins målgrupp. Det fick skrivas en annan kapiteltext, men det
kom samtidigt ett förslag att publicera texten om parsning här som denna rapport.},

Unlike previous models, based solely on a certain aspect of language abilities (i.e. on written or spoken language alone), the project is comprehensive and more likely to provide new insights in the area of dementia detection and improve practices applied so far. The project builds on the success stories of the past and focus on the interplay between various types of technologies that hold the potential to provide reliable estimates for the detection of cognitive decline. The project emphasizes its interdisciplinary nature, by bringing together researchers from humanities (computational linguistics / language technology), computer science and medicine, and foresees the development of a comprehensive set of novel analytic approaches not explored jointly in the past
GOAL: discovering evidence about linguistic performance and identifying whether the addition of new ways for investigating, combining and evaluating measurement and other parameters for improvement of established models can advance our understanding of: i) the boundaries between normal aging and dementia; ii) its effects on linguistic performance extrapolated from various sources and iii) whether effects of cognitive decline can be seen across (daily) language production.

abstract = {The purpose of the Workshop on “Resources and ProcessIng of linguistic and extra-linguistic Data
from people with various forms of cognitive/psychiatric impairments” (RaPID-2016) was to provide
a snapshot view of some of the current technological landscape, resources, data samples and also
needs and challenges in the area of processing various data from individuals with various types of
mental and neurological health impairments and similar conditions at various stages; increase the
knowledge, understanding, awareness and ability to achieve useful outcomes in this area and
strengthen the collaboration between researchers and workers in the field of clinical/nursing/medical
sciences and those in the field of language technology/computational linguistics/Natural Language
Processing (NLP).
Although many of the causes of cognitive and neuropsychiatric impairments are difficult to foresee
and accurately predict, physicians and clinicians work with a wide range of factors that potentially
contribute to such impairments, e.g., traumatic brain injuries, genetic predispositions, side effects of
medication, and congenital anomalies. In this context, there is new evidence that the acquisition and
processing of linguistic data (e.g., spontaneous story telling) and extra-linguistic and production
measures (e.g., eye tracking) could be used as a complement to clinical diagnosis and provide the
foundation for future development of objective criteria to be used for identifying progressive decline
or degeneration of normal mental and brain functioning.
An important new area of research in NLP emphasizes the processing, analysis, and interpretation of
such data and current research in this field, based on linguistic-oriented analysis of text and speech
produced by such a population and compared to healthy adults, has shown promising outcomes. This
is manifested in early diagnosis and prediction of individuals at risk, the differentiation of individuals
with various degrees of severity forms of brain and mental illness, and for the monitoring of the
progression of such conditions through the diachronic analysis of language samples or other extralinguistic
measurements. Initially, work was based on written data but there is a rapidly growing body
of research based on spoken samples and other modalities.
Nevertheless, there remains significant work to be done to arrive at more accurate estimates for
prediction purposes in the future and more research is required in order to reliably complement the
battery of medical and clinical examinations currently undertaken for the early diagnosis or
monitoring of, e.g., neurodegenerative and other brain and mental disorders and accordingly, aid the
development of new, non-invasive, time and cost-effective and objective (future) clinical tests in
neurology, psychology, and psychiatry.},

However, there are many languages which are not yet automatically processed, for instance minority and informal languages. Many of these languages are only spoken and do not exist in a written format. Social media platforms and new technologies have facilitated the emergence of written format for these spoken languages based on pronunciation. The latter are not well represented on the Web, commonly referred to as under-resourced languages, and the current available ALI tools fail to properly recognize them. In this paper, we revisit the problem of ALI with the focus on Arabicized Berber and dialectal Arabic short texts. We introduce new resources and evaluate the existing methods. The results show that machine learning models combined with lexicons are well suited for detecting Arabicized Berber and different Arabic varieties and distinguishing between them, giving a macro-average F-score of 92.94%.},

title = {Retrieving Occurrences of Grammatical Constructions},
abstract = {Finding authentic examples of grammatical constructions is central in constructionist approaches to linguistics, language processing, and second language learning. In this paper, we address this problem as an information retrieval (IR) task. To facilitate research in this area, we built a benchmark collection by annotating the occurrences of six constructions in a Swedish corpus. Furthermore, we implemented a simple and flexible retrieval system for finding construction occurrences, in which the user specifies a ranking function using lexical-semantic similarities (lexicon-based or distributional). The system was evaluated using standard IR metrics on the new benchmark, and we saw that lexical-semantical rerankers improve significantly over a purely surface-oriented system, but must be carefully tailored for each individual construction.

title = {Gulf Arabic Resource Building for Sentiment Analysis},
abstract = {This paper deals with building linguistic resources for Gulf Arabic, one of the Arabic variations, for sentiment analysis task using machine learning. To our knowledge, no previous works were done for Gulf Arabic sentiment analysis despite the fact that it is present in different online platforms. Hence, the first challenge is the absence of annotated data and sentiment lexicons. To fill this gap, we created these two main linguistic resources. Then we conducted different experiments: use Naive Bayes classifier without any lexicon; add a sentiment lexicon designed basically for MSA; use only the compiled Gulf Arabic sentiment lexicon and finally use both MSA and Gulf Arabic sentiment lexicons. The Gulf Arabic lexicon gives a good improvement of the classifier accuracy (90.54 %) over a baseline that does not use the lexicon (82.81%), while the MSA lexicon causes the accuracy to drop to (76.83%). Moreover, mixing MSA and Gulf Arabic lexicons causes the accuracy to drop to (84.94%) compared to using only Gulf Arabic lexicon. This indicates that it is useless to use MSA resources to deal with Gulf Arabic due to the considerable differences and conflicting structures between these two languages.},

title = {Syllable Repetition vs. Finger Tapping: Aspects of Motor Timing in 100 Healthy Adults.},
abstract = {In this study we systematically compared syllable repetition and finger tapping in healthy adults, and explored possible impacts of tempi, metronome, musical experience, and age on motor timing ability. One hundred healthy adults used finger-tapping and syllable repetition to perform an isochronous pulse in three different tempi, with and without a metronome. Results showed that the motor timing was more accurate with finger tapping than with syllable repetition in the slowest tempo, and the motor timing ability was better with the metronome than without. Persons with musical experience showed better motor timing accuracy than persons without such experience, and the timing asynchrony increased with increasing age. The slowest tempo 90 bpm posed extra challenges to the participants. We speculate that this pattern reflects the fact that the slow tempo lies outside the 3-8 Hz syllable rate of natural speech, which in turn has been linked to theta-based oscillations in the brain.},

The data we are currently collecting consists of audio-recorded spoken language samples; transcripts of the audio recordings and eye tracking measurements. From these data we plan to extract, evaluate and model features to be used for learning classification models in order to test how well a differentiation between the aforementioned subject groups can be made. Features will be also correlated with outcomes from e.g. other language-related scores, such as word fluency, in order to investigate whether there are relationships between various variables.},
