    News Coverage, the Expansion of Discourse, and Conflict

    The universe of news cultures--comprising providers and consumers-has never been static. It perpetually evolves, sometimes in small increments, sometimes with dazzling leaps. We are now in one of the latter phases, with new technologies driving change at high speed. This alteration of the news universe is a mix of reshaping and expansion, and it has a profound effect on social and political life throughout much of the world. It has particular impact on how policy makers and the public evaluate and respond to conflict

    Reinventing ‘Many Voices’: MacBride and a Digital New World Information and Communication Order

    The MacBride Commission Report was arguably one of the most significant multilateral interventions in the history of international communication. This article charts its emergence at the time of deeply contested Cold War politics, coinciding with the rise of the southern voices in the global arena, led by the non-aligned nations. Thirty-five years after the report's publication, has the global media evolved into a more democratic system, demonstrating greater diversity of views and viewpoints? Despite the still formidable power of US-led western media, the article suggests that the globalisation and digitisation of communication has contributed to a multi-layered and more complex global media scene, demonstrating the “rise of the rest”

    Large expert-curated database for benchmarking document similarity detection in biomedical literature search

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
