Native Language Identification (NLI) is a task aimed at determining the native language (L1) of learners of second language (L2) on the basis of their written texts. To date, research on NLI has focused on relatively small corpora. We apply NLI to the recently released EFCamDat corpus which is not only multiple times larger than previous L2 corpora but also provides longitudinal data at several...

This paper tests a theory of social uses of the Internet (L opez-Sintas, Filimon, & GarcíaAlvarez, 2012), inspired by the work of Bourdieu (1984, 1986, 1989), outside the Spanish national context in which it was initially formulated. Using the OECD's PISA 2012 data for Germany and Norway, it specifically seeks to uncover differences in patterns of Information and Communication Technologies usag...

In this paper, we describe the approach of the ItaliaNLP Lab team to native language identification and discuss the results we submitted as participants to the essay track of NLI Shared Task 2017. We introduce for the first time a 2-stacked sentencedocument architecture for native language identification that is able to exploit both local sentence information and a wide set of general–purpose f...

This paper discusses and implements features both for a mobile Web and for a mobile native application, capable to provide news services enriched with indicative social networking elements. The objective was to facilitate the involvement of mobile users to produce and upload new content on the News Website and to facilitate their participation in the promotion and evaluation of the existing con...

We present a system for automatically identifying the native language of a writer. We experiment with a large set of features and train them on a corpus of 9,900 essays written in English by speakers of 11 different languages. our system achieved an accuracy of 43% on the test data, improved to 63% with improved feature normalization. In this paper, we present the features used in our system, d...

The main results: A ring R is CN if and only if for any x ∈ N(R) and y ∈ R, ((1+x)y)n+k = (1+x)n+kyn+k, where n is a fixed positive integer and k = 0, 1, 2; (2) Let R be a CN ring and n ≥ 1. If for any x, y ∈ R\N(R), (xy)n+k = xn+kyn+k, where k = 0, 1, 2, then R is commutative; (3) Let R be a ring and n ≥ 1. If for any x ∈ R\N(R) and y ∈ R, (xy)k = xkyk, k = n, n + 1, n + 2, then R is commutati...

Mobile services hold a promise of utilizing the phone also for other purposes than purely communication. However, repeated attempts at realizing mobile services in the market place have been met with limited success. This article (1) defines the architectural drivers that drive success or failure of mobile services, (2) analyzes three different architectural styles of realizing such a mobile se...

As the field nephrology is rapidly advancing, technological changes are changing the face of learning. Understanding how the current generation of “digital natives” learn and understand topics is vastly important. The current students and residents were born when computers and electronic gadgets were considered a part and parcel of their learning structures. The primary focus of this review is ...

²Web Services Resource Framework (WSRF) redefines Grid Services standards and extends Web Services by adding stateful resources. Using GT4 to develop WSRF Grid Services is a taxing work, and it is difficult to build and deploy these services dynamically. Addressing these issues, this paper proposes a unified service platform which can provide a series of unified service interfaces for accessing...

The role of direct methods in macromolecular crystallography is discussed. The common belief that such methods will still remain marginal is rejected. Different sectors are analyzed. A direct procedure for phasing reflections when diffraction data of one isomorphous derivative are available is briefly described. The applications to experimental data of some test structures succeeded, and sugges...
