Government and Social Media: A Case Study of 31 Informational World Cities
Social media platforms are increasingly being used by governments to foster
user interaction. Particularly in cities with enhanced ICT infrastructures
(i.e., Informational World Cities) and high internet penetration rates, social
media platforms are valuable tools for reaching high numbers of citizens. This
empirical investigation of 31 Informational World Cities will provide an
overview of social media services used for governmental purposes, of their
popularity among governments, and of their usage intensity in broadcasting
information online.Comment: In Proceedings of the 47th Hawaii International Conference on System

Promoting learner autonomy through multiliteracy skills development in cross-institutional exchanges
This contribution presents findings from two empirical case studies, which followed a task-based telecollaborative learning format. Participants included student teacher trainees, tutors, and language learners from colleges/universities in Germany, Poland, the United Kingdom, and the United States. The projects aimed at promoting learner autonomy through awareness raising of modes and meaning-making online and multiliteracy skills development based on hands-on analysis of web resources and social networking tools.
It was hoped that this awareness would foster the teachers' own autonomy in virtual learning environments and enable them to design tasks whichâin turnâwould promote learner autonomy as understood by Palfreyman (2006): the informed use of a range of interacting resources in context. We argue that this awareness is reflected in enhanced multimodal communicative competence, i.e., âthe ability to understand the combined potential of various modes for making meaningâ (Royce, 2002, p. 92), and multiliteracy, with the latter allowing teachers and learners to realize the potential of blended and online only settings for language acquisition purposes. Ideally then, while becoming gradually more versed in multimodality and multiliteracy, learners can also take over more control and self-direct their own learning when working online (Benson, 2001) which are also characteristics of autonomy
Punctuation effects in English and Esperanto texts
A statistical physics study of punctuation effects on sentence lengths is
presented for written texts: {\it Alice in wonderland} and {\it Through a
looking glass}. The translation of the first text into esperanto is also
considered as a test for the role of punctuation in defining a style, and for
contrasting natural and artificial, but written, languages. Several log-log
plots of the sentence length-rank relationship are presented for the major
punctuation marks. Different power laws are observed with characteristic
exponents. The exponent can take a value much less than unity ( 0.50 or
0.30) depending on how a sentence is defined. The texts are also mapped into
time series based on the word frequencies. The quantitative differences between
the original and translated texts are very minutes, at the exponent level. It
is argued that sentences seem to be more reliable than word distributions in
discussing an author style.Comment: 13 pages, 7 figures (3x2+1), 60 reference
Data Innovation for International Development: An overview of natural language processing for qualitative data analysis
Availability, collection and access to quantitative data, as well as its
limitations, often make qualitative data the resource upon which development
programs heavily rely. Both traditional interview data and social media
analysis can provide rich contextual information and are essential for
research, appraisal, monitoring and evaluation. These data may be difficult to
process and analyze both systematically and at scale. This, in turn, limits the
ability of timely data driven decision-making which is essential in fast
evolving complex social systems. In this paper, we discuss the potential of
using natural language processing to systematize analysis of qualitative data,
and to inform quick decision-making in the development context. We illustrate
this with interview data generated in a format of micro-narratives for the UNDP

Group influence on blogs design behaviour
Issues of national culture influence on web design behaviour have been rampant and stimulating on static web pages across the globe. The emergence of a new breed of publication-type web page brought about by the advancement of web technology however, saw a different species of online communication groups. Bloggers as these groups are called; used blogs as their communication and publication tool to distinguish themselves from other websites and online social media users. Since bloggers are groups that are recognised and credited to cultivate their own culture, the idea that national culture has an influence on blogs design behaviour and preferences may have been weakened. Bloggers groups themselves would be the influential factor that determines design preferences of bloggers in a network of blogs. To address the issue, this paper has conducted an assessment on blogs from six countries using content analysis method, national culture traits and SIDE model to ascertain design features characteristics and behaviour. Results from both the global and local blogs in each country showed that blogs design preferences in one country differ between both the global and local bloggers. Furthermore, global bloggers design preferences in countries under observation are found to be similar to one another
Cross-lingual Argumentation Mining: Machine Translation (and a bit of Projection) is All You Need!
Argumentation mining (AM) requires the identification of complex discourse
structures and has lately been applied with success monolingually. In this
work, we show that the existing resources are, however, not adequate for
assessing cross-lingual AM, due to their heterogeneity or lack of complexity.
We therefore create suitable parallel corpora by (human and machine)
translating a popular AM dataset consisting of persuasive student essays into
German, French, Spanish, and Chinese. We then compare (i) annotation projection
and (ii) bilingual word embeddings based direct transfer strategies for
cross-lingual AM, finding that the former performs considerably better and
almost eliminates the loss from cross-lingual transfer. Moreover, we find that
annotation projection works equally well when using either costly human or
cheap machine translations. Our code and data are available at
