Variation ontology: annotator guide

Variation ontology: annotator guide

BACKGROUND Systematic representation of information related to genetic and non-genetic variations is required to allow large scale studies, data mining and data integration, and to make it possible to reveal novel relationships between genotype and phenotype. Although lots of variation data is available it is often difficult to use due to lack of systematics. RESULTS A novel ontology, Variati...

A Rule-based Semantic Annotator: Adding top-level ontology Tags

Understanding natural language texts is a simple task for human beings, but despite recent advances, it is still a challenge for computational devices. An important step in allowing machines to understand texts in natural language is to annotate lexemes with semantic information. Semantic information has several levels and aspects, but a type of semantic annotation that has the ability to help ...

Sequence Ontology Annotation Guide

This Sequence Ontology (SO) [13] aims to unify the way in which we describe sequence annotations, by providing a controlled vocabulary of terms and the relationships between them. Using SO terms to label the parts of sequence annotations greatly facilitates downstream analyses of their contents, as it ensures that annotations produced by different groups conform to a single standard. This great...

A Hitchhiker's Guide to Ontology

In this talk, I will present our recent work in the area of knowledge bases. It covers 4 areas of research around ontologies and knowledge bases: The first area is the construction of the YAGO knowledge base. YAGO is now mulitlingual, and has grown into a larger project at the Max Planck Institute for Informatics and Télécom ParisTech. The second area is the alignment of knowledge bases. This i...
