Browse ComptoxAI data

ComptoxAI provides several flexible options for browsing its graph database. These different options are intended for various users and use case scenarios.

Interactive data portal

Level of usability: Beginner

Launch data portal

The interactive data portal is a simplified interface for ComptoxAI's graph database. Users can interactively search for nodes (entities) in the database by specifying a node type (e.g., "Chemical", or "Disease") and querying properties that are defined for that node type. When you select a node, you can then load all relationships that the node has with other nodes in the graph database.

The data portal also includes a tool for visualizing the shortest paths connecting any two nodes in the database. To use this, find two nodes separately using the node search tool, and click "Path Start Node" and "Path End Node" respectively. The shortest path between the two nodes will be identified, and it will be reconstructed into a graph visualization of the nodes and relationships comprising the shortest path. The visualization interface allows panning, zooming, and selecting individual nodes in the path for further inspection.

Neo4j Graph Database browser

Level of usability: Intermediate

Launch Neo4j browser
Note: Users do not need to authenticate to access the database. Click "Connect" on the authentication form using the default options to access the database in read-only mode.
ComptoxAI in Protege

ComptoxAI's graph database is implemented using the Neo4j graph database management system. The Neo4j browser is an interface that allows users to graphically interact with nodes and relationships in the database by either randomly sampling node or relationship types, or by executing database queries in the Cypher query language (which is analogous to SQL, but designed for use with graph databases rather than relational databases).

We recommend that new users read the official "Introduction to Cypher" tutorial to learn how to get the most out of the Neo4j interface.

Web API documentation

ComptoxAI's REST Web API allows programmatic access to the graph database. The base URL for the API is:

ComptoxAI OWL2 Ontology

Level of usability: Advanced

Download ontology without individuals (103 KB) Download fully-populated ontology (598 MB)

The contents of ComptoxAI's graph database are extracted from a large, fully-featured OWL2 ontology that defines the semantic meaning of each entity and relationship in the database, as well as each of the data properties attached to each node.

ComptoxAI in Protege

The ontology plays a central role in the development of ComptoxAI. Briefly, the database maintainers first specify the types of entities and the relationships between them by constructing a class hierarchy in the ontology, and then define the types of relationships—known as object properties—that can link those types of relationships. The ontology is then populated with individuals (nodes in the database) by parsing source databases and storing the individual elements as instances of those node types, and the same is done for relationships between the elements. Finally, the contents of the ontology are imported into Neo4j using the neosemantics (n10s) extension tool, which converts OWL2 data into a Neo4j database.

We like to use Protege to view and edit ontologies.
