A SNOMED CT Browser offers a user-friendly view of the terminology to support basic functions like:

• Search: Browser provide the ability to search SNOMED CT content using terms, partial terms, or component identifiers. Browsers can also provide different ways to filter the search results, by active status, semantic tag, module, etc.

• Hierarchy navigation: Most browsers provide a way for the user to navigate the SNOMED CT hierarchy via the parents and children of each concept.

• Concept details: Browsers allow users to view the properties of each component, including the identifiers, effective times, descriptions, axioms, relationships and reference set members.

• Reference set browsing: Some browsers present a list of available reference sets and display their member components and attribute values.

• ECL queries: Some browsers allow users to enter and execute ECL (Expression Constraint Language) queries. ECL provides an advanced mechanism to filter SNOMED CT content and is used to support a range of implementation use cases, including constraining data entry in clinical applications, supporting meaning-based data analytics, and quality assurance.

• Graphical views: Some browsers can display the definition of each concept as a diagram which follows the SNOMED diagramming guidelines, or display a graph that shows the hierarchical relationships between a set of concepts.
