Skip graphs are a novel distributed data structure, based on skip lists, that provide the full functionality of a balanced tree in a distributed system where resources are stored in separate nodes that may fail at any time. They are designed for use in searching peer-to-peer systems, and by providing the ability to perform queries based on key ordering,(More)
In this paper, we explore the use of domain-independent and domain-specific ontologies to find matching service descriptions. The domain-independent relationships are derived using an English thesaurus after tokenization and part-of-speech tagging. The domain-specific ontological similarity is derived by an inference on the semantic annotations associated(More)
One of the principal problems in Information Lifecycle Management is to align the business value of data with the most cost-effective and appropriate storage infrastructure. In this paper, we present ACE: a framework of tools for ILM, that classifies data and storage resources, and generates a data placement plan for informed utilization of the available(More)
Poisoning is a common preventable cause of morbidity and mortality in children. Most of the poisoning in children less than 5 years of age is accidental. Objective of the study was to study the clinical profile and outcome of childhood poisoning and intoxication. This was a retrospective study done in patients who were admitted in pediatric wards and(More)
BACKGROUND Pneumonia is a leading cause of morbidity and mortality in children. OBJECTIVE The aim of study was to evaluate the efficacy of Zinc supplementation in treatment of severe pneumonia in hospitalized children. DESIGN/METHODS A double blind randomized, placebo- controlled clinical trial conducted at a tertiary care centre of a teaching hospital.(More)
In this paper, we address the problem of searching schema databases for semantically-related schemas. We first give a method of finding semantic similarity between pair-wise schemas based on tokenization, part-of-speech tagging, word expansion, and ontology matching. We then address the problem of indexing the schema database through a semantic hash table.(More)
