This paper describes the University of Sydney’s WSD and Lexical Substitution systems for SemEval-2007. These systems are principally based on evaluating the substitutability of potential synonyms in the context of the target word. Substitutability is measured using Pointwise Mutual Information as obtained from the Web1T corpus. The WSD systems are supervised, while the Lexical Substitution syst...

There is a renewed interest in word sense disambiguation (WSD) as it contributes to various applications in natural language processing. Applications for which WSD is potentially an issue are: Machine Translation, Information Retrieval (IR), QA systems, Dialogue systems,etc. In this paper we survey vector-based methods for WSD in machine learning approache.

In this paper we revisit the classical NLP problem of prepositional phrase attachment (PPattachment). Given the pattern V −NP1−P−NP2 in the text, where V is verb,NP1 is a noun phrase, P is the preposition and NP2 is the other noun phrase, the question asked is where does P −NP2 attach: V or NP1? This question is typically answered using both the word and the world knowledge. Word Sense Disambig...

background: this was a population-based study to examine whether the campaign for world aids day 2005 in iran was suc­cessful. methods: a random sample of the general population was asked whether they had seen the campaign and knew the mes­sage. they were also asked whether it was attractive; there was anything offensive, whether the campaign could raise aware­ness, and how they rated the campa...

the 21st century is an era of great challenge for humankind; we are combating terrorism, climate change, poverty, human rights issues and last but not least non-communicable diseases (ncds). the burden of the latter has become so large that it is being recognized by world leaders globally as an area that it is in need of much greater attention. in light of this concern, the world health organiz...

The definition of sepsis was updated to sepsis-3 in February 2016. However, the performance of the previous and new definition of sepsis remains unclear in China. This was a retrospective multicenter study in six intensive care unit (ICUs) from five university-affiliated hospitals to compare the performance between sepsis-1 and sepsis-3 in China. From May 1, 2016 to June 1, 2016, 496 patients w...

background: sepsis is a common clinical diagnosis. knowing the outcome of these patients is very important because it alerts the physicians. the goal of this research is to find an easy, inexpensive and accessible way for this purpose and to study the correlation between thyroid hormones and cortisol levels and the outcome of patients in sepsis. methods: in this study 55 sepsis patients were ex...

An electronic sepsis surveillance system (ESSV) was developed to identify severe sepsis and determine its time of onset. ESSV sensitivity and specificity were evaluated during an 11-day prospective pilot and a 30-day retrospective trial. ESSV diagnostic alerts were compared with care team diagnoses and with administrative records, using expert adjudication as the standard for comparison. ESSV w...
