The record

Purpose: Semaphore provides a semantic layer for generative AI intended to support explainable, relevant, and trustworthy outcomes.
Capabilities: The modular platform manages knowledge models, extracts facts, classifies structured and unstructured information, and generates semantic metadata.
AI uses: The AI page lists conversational agents, document Q&A systems, semantic enterprise search, and content generation as use cases.
RAG: Semantic RAG augments prompts with enterprise data to produce contextually relevant responses and reduce hallucinations and data biases.
Governance: Business users moderate and instruct Semaphore, while subject matter experts manage, develop, and maintain knowledge models.
Transparency: Knowledge models and metadata provide a clear picture of information used and actions taken in the decision-making process.
Integrations: Progress documentation lists integration guides for MarkLogic, NiFi, OpenText, SharePoint Online, Sitecore, Solr, and WAND.
Security and governance: The AI page says semantic RAG adheres to enterprise standards for governance, lineage, and provenance.
Trial: The 30-day trial provides a personalized cloud environment, access to all capabilities, and guided onboarding.
Trial activities: During the trial, users can build an ontology, improve RAG retrieval quality, classify documents, test semantic search, and validate AI use cases with their own data.
Support: Progress lists a Support Center for logging and tracking support incidents.
Founded: 1981
Headquarters: Burlington, Massachusetts, USA
