People in the locality of earthquakes are publishing anecdotal information about the shaking within seconds of their occurrences via social network technologies, such as Twitter. In contrast, depending on the size and location of the earthquake, scientific alerts can take between two to twenty minutes to publish. We describe TED (Twitter Earthquake Detector) a system that adopts social network ...

data envelopment analysis (dea) is one of the scientific method that computes the efficiency by using a powerful mathematics basic. data envelopment analysis is a non-parametric technique to evaluate the efficiency of a set of decision making units (dmu) with multi inputs and outputs . since dea’s models classifies decision making units into two categories of efficient and inefficient, so most ...

Scientific publication is immensely important to the scientific endeavour. There is, however, concern that rewarding scientists chiefly on publication creates a perverse incentive, allowing careless and fraudulent conduct to thrive, compounded by the predisposition of top-tier journals towards novel, positive findings rather than investigations confirming null hypothesis. This potentially compo...

Recent decades have seen a trend towards scientific publications with many authors. There is not an agreed way of counting coauthored publications. This research in progress contribution compares the behaviour of four representative methods of counting research outputs. We present differences between those methods of counting evaluated at the level of whole universities, their faculties, or non...

Natural language processing (NLP) is a sub-field of computational sciences which addresses the operation and management of texts, as inputs or outputs of computational devices. As such, this domain includes a large amount of distinct topics, depending which particular service is considered. Nowadays, with the Internet spreading as a worldwide tremendous reservoir of knowledge, NLP is highly sol...
