		<h3>Welcome to Ontae!</h3>
		<p>Ontae is a web-based ontology-based vaccine adverse event (VAE) case reporting and analysis system. </p>
		<p>The Vaccine Adverse Event Reporting System (VAERS, <a href="http://www.vaers.hhs.gov/">http://www.vaers.hhs.gov/</a>)   is an official vaccine post-marketing safety surveillance program that   collects information about adverse events that occur after the   administration of US licensed vaccines. VAERS is supported by the   Medical Dictionary for Regulatory Activities (MedDRA) as a controlled   terminology system. However, MedDRA has many disadvantages including the   lack of definitions of terms and term relations. </p>
		<p>An ontology is a   system of consensus-based controlled vocabularies of terms and their   relationships, with associated definitions that are logically formulated   in such a way as to promote automated reasoning. Ontae primarily relies on two ontologies: the Ontology of Adverse Events (OAE), and the Vaccine Ontology (VO; <a href="http://www.violinet.org/vaccineontology/">http://www.violinet.org/vaccineontology/</a>). OAE ontologically represents various adverse events. VO includes all licensed human vaccines. The integrative usage of OAE and VO supports our Ontae development. </p>

  		<p>Ontae VAE analysis system stores all the  publicly available VAE data from VAERS system and provides both web-based data  query and analysis components. The same setting can also be used to query the  VAE data reported from our own VAE reporting system. Our Ontae  analysis  system will be developed to analyze the VAE data from VAERS as well as the data  reported to our own VAE reporting system.</p>
