Gene Ontology Meta Annotator for Plants (GOMAP)

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...

The NCBO Annotator: Ontology-Based Annotation as a Web Service

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 ...

Inter-Annotator Agreement on a Linguistic Ontology for Spatial Language - A Case Study for GUM-Space

In this paper, we present a case study for measuring inter-annotator agreement on a linguistic ontology for spatial language, namely the spatial extension of the Generalized Upper Model. This linguistic ontology specifies semantic categories, and it is used in dialogue systems for natural language of space in the context of human-computer interaction and spatial assistance systems. Its core rep...

An Ontology-Based Multimedia Annotator for the Semantic Web of Language Engineering

The development of the Semantic Web, the next-generation Web, greatly relies on the availability of ontologies and powerful annotation tools. However, there is a lack of ontology-based annotation tools for linguistic multimedia data. Existing tools either lack ontology support or provide limited support for multimedia. To fill the gap, we present an ontology-based linguistic multimedia annotati...
