With the increasing number of mobile platforms available, developers aiming to bring their products to the larger number possible of consumers are required to program for different platforms, using different development environments, and often resulting in applications with different user experiences. A possible solution for this problem are development frameworks supporting develop once, deplo...

Attempts to profile authors based on their characteristics, including native language, have drawn attention in recent years, via several approaches using machine learning with simple features. In this paper we investigate the potential usefulness to this task of contrastive analysis from second language acquistion research, which postulates that the (syntactic) errors in a text are influenced b...

We outline the first application of Native Language Identification (NLI) to Finnish learner data. NLI is the task of predicting an author’s first language using writings in an acquired language. Using data from a new learner corpus of Finnish — a language typology quite different from others previously investigated, with its morphological richness potentially causing difficulties — we show that...

Most current statistical models for downscaling the remotely sensed land surface temperature (LST) are based on the assumption of the scale-invariant LST-descriptors relationship, which is being debated and requires an in-depth examination. Additionally, research on downscaling LST to high or very high resolutions (~10 m) is still rare. Here, a simple analytical model was developed to quantify ...

background heat, chemical and organic pollution are three types of environmental pollution, caused by refinery and petrochemical industries. problems caused by hear and chemical pollutants are currently resolved to some extent but organic pollution such as poly aromatic hydrocarbons (pahs) are still considered as important problems of industry and environment. objectives a laboratory study was ...

Tests of foreign accent usually treat native listeners as reliable providers of accentedness ratings, and pay too little heed to task-specific effects on non-native speakers' performance. This paper details a number of factors which in fact influence native listeners' perceptions, and the nativelike behaviour of non-native speakers' productions, based on the results of a large study of phonetic...

The effects of synthesized voice warning parameters on perceived urgency were examined in order to build a detailed and usable description of the relation between the parameters of synthesized voice warnings and perceived urgency. Ten native and 10 non-native English speakers participated in 4 experiments to evaluate and quantify the effects of the voice parameters. The results showed that spee...

This study examines the coda voicing effect in English on production of preceding vowel by comparing L1 and L2 speech. Particular attention is paid to how coda voicing contrast is encoded in temporal vs. spectral dimensions, how the effect interacts with information structure (with varying focus types), and how the use of information structure differs in L1 vs. L2. Both English (native) and Kor...

In this paper, we systematically explore lexicalized and non-lexicalized local syntactic features for the task of Native Language Identification (NLI). We investigate different types of feature representations in singleand cross-corpus settings, including two representations inspired by a variationist perspective on the choices made in the linguistic system. To combine the different models, we ...

His companion papers spurred large amounts of research, debating changes that are requ...
