TogoStanza

TogoStanza integrates RDF-encoded genomic and annotation data and provides Semantic Web components for SPARQL-based querying and semantic comparative genomics.

Key Features:

• Semantic Web integration: Uses Resource Description Framework (RDF) for data representation and SPARQL for dynamic querying to integrate heterogeneous genomic datasets.
• Modular architecture: Implements independently deployable modules usable as IFRAMEs or Web Components to expose reusable information blocks within genome resources.
• Semantic-faceted search: Enables ontology-driven faceted search across gene functional annotations, taxonomy, phenotypes, and environmental factors.
• Comparative genomics interface: Supports semantic comparative genomics to identify pan-organism and organism-specific genes using functional annotations and cross-taxa combinations.

Scientific Applications:

• Semantic data integration: Integrates heterogeneous genomic datasets into an RDF-based knowledge graph to support cross-dataset queries.
• Gene discovery and annotation queries: Facilitates discovery of genes and annotations via ontology-based faceted searches across function, taxonomy, phenotype, and environment.
• Comparative genomics analyses: Enables cross-taxa analyses to identify pan-organism and organism-specific gene sets based on semantic annotations.

Methodology:

Represents data in RDF, employs ontologies for semantic annotation, and executes SPARQL queries for data retrieval and semantic faceted search.
