rsemmed

rsemmed provides a programmatic interface to the Semantic MEDLINE database for searching biomedical concepts, finding paths between concepts, and summarizing and visualizing those paths.

Key Features:

• Concept Search: Provides functions for searching the Semantic MEDLINE database for biomedical concepts.
• Path Finding: Finds paths between concepts in the Semantic MEDLINE database.
• Customizable Path Searching: Path searching can be tailored by placing restrictions on concept types and the type of link between concepts.
• Summarization: Provides functions for summarizing paths between concepts.
• Visualization: Provides functions for visualizing paths between concepts.

Scientific Applications:

• Biomedical Literature Mining: Enables programmatic access to the Semantic MEDLINE database for extracting relationships between biomedical concepts.
• Knowledge Graph Exploration: Supports discovery of connections between concepts in biomedical knowledge networks with user-specified constraints.

Methodology:

The package interfaces programmatically with the Semantic MEDLINE database to query concepts and traverse paths between them, with optional filtering by concept types and link types.
