Online digital library sampling based on query related graph

Purpose Digital library sampling is used to obtain a collection of random literature records from the backend database, which is a crucial issue for a variety of important purposes in many online digital library applications. Digital libraries can only be accessed through their query interfaces. The challenge is how to ensure the randomness of the sample via the autonomous query interface. Design/methodology/approach This paper presents an iterative and incremental approach to obtain samples through the query interface of a digital library. In the approach, a novel graph model, query-related graph, is proposed to transform the flat literature records into a graph structure, and samples are obtained iteratively by traveling the query-related graph. Besides query-related graph, the key components, query generation, termination condition and amending deviation, are also discussed in detail. Findings The extensive experiments over two real digital libraries, ISTIC and IEEE Xplore, show the proposed approach results in a better performance. First, the approach is very effective to obtain high-quality samples which are evaluated by the measure “sample deviation.” Second, the sampling process is very efficient by only submitting fewer random queries. Third, the approach is robust. Research limitations/implications This sampling approach is limited by the query interfaces on a web page. In rare cases (<3 per cent), this approach cannot access query interfaces by sophisticated techniques. Practical implications Digital library sampling is very useful for a variety of important purposes: subject distribution analysis, literature quality evaluation, digital library size estimation, source selection in digital library integration and content freshness evaluation. Social implications Myriads of online digital libraries can be accessed online. Digital library sampling is a useful way to understand digital libraries for many important applications. Originality/value Most of the attributes of a digital library query interface have infinite values, such as keyword attributes, which cannot be handled effectively by the existing sampling approaches.

Evidence-based nursing on the extubation early of stomach tube after hepatectomy

Objective To utilize evidence-based nursing to extubate stomach tube early for one patients with postoperative hepatectomy, and to evaluate clinical effects and the impact on postoperative rehabilitation. Methods According to patient′s condition and clinical issues of PICO principle, we retrieve Ovid-EBM Reviews, Medline, Trip Database, CNKI, Wanfang Database, VIP Database and so on from 1995 to 2014 to acquire the clinical guideline, system evaluation, random control trail, evidence abstract and literature review and other evidences, and assess the quality of acquired evidences. Results There were 2 system evaluation, 3 random control trail, 1 non-random control trail. The extubation of stomach tube early after hepatectomy could minimize the discomfort incidences of pharynx, promote the recovery of gastrointestinal function, and could not increase the complication incidences of patients′ nausea, vomiting, ventosity, pulmonary infections and so on. Combined with patient′s condition and intention, the stomach tube could be extubate 10 hrs after hepatectomy and patients could discharged 7 d after operation. Conclusions The extubation of stomach tube early after hepatectomy is a safe and feasible method which is beneficial for patients′ recovery. Key words: Hepatectomy; Stomach tube; Postoperative complications; Evidence-based nursing

A Cost Efficient Algorithm for System Reliability Calculation with Aleatory and Epistemic Uncertainties Using Evidence Theory

In reliability calculation of complex system, it is always in the situation that experimental data is inadequate, or information is not complete, which makes the system not only involving aleotory uncertainty, but also epistemic uncertainty. To reduce the cost of reliability calculation, an effective approach with evidence theory is developed. In this approach, the mean of belief and plausibility function is taken as the approximation of system reliability. The discretization methods for uncertain parameters are discussed when system involves only aleatory uncertainty, and involves aleatory and epistemic uncertainties simultaneously, respectively. Algorithms for belief and plausibility function evaluation are proposed for monotonic and non-monotonic system. Four numerical examples with different conditions are studied. Simulation results show that, the proposed method is much more effective than Monte Carlo method without sacrificing the accuracy of resulting reliability, and is a general method which is applicable for various systems with different types of information

On Communicating the Uncertainty of Risk

There are now a number of guides to help civil engineering professionals communicate risk. However the available techniques to deliberate on, identify and manage risk still require development especially for dealing with uncertain open world ‘wicked’ problems with low probability and high impact as confirmed by a recent high level government review in the UK. A well known, but not well understood, paradox at the heart of practical life is that on the one hand we routinely make risky practical decisions perfectly well but on the other hand our judgements about statistically testable risks are sometimes significantly in error. We maintain that managing uncertainty is the key; that classifying uncertainty as either aleatoric or epistemic is insufficient; and that standard probability theory has to become an interval measure which we characterise as an ‘Italian Flag’. A framework is proposed, based on evidence theory, through which all types of uncertainties about risk can be expressed in a way which is simpler to communicate, easier to understand and hence is a basis for improved risk management
