Today’s enterprises need unfettered-yet-intentional access to information. By combining methods like a unified index, hybrid retrieval, user behavior, and numerous machine learning models to not only source related documents but also evaluate by relevance, enterprises can build a dynamic experience that scales as their business does.
Unified Index
A unified index centralizes access to data across all sources and repositories. This way, a user does not need to know where a document is stored; instead, they can simply query the index and get a response. Coveo’s unified index also incorporates early-binding security (meaning it indexes permissions at the document level) and role-based access controls, so users only ever have access to the documents they have permission to see.
Documents are also chunked and vectored at time of indexing, making it easier to quickly retrieve relevant passages instead of whole documents. This provides guardrails against AI hallucinations and bad answers.
Hybrid Retrieval
Hybrid retrieval combines the precision of lexical search with the contextual understanding of semantic search. The information retrieval system first uses a lexical method to retrieve documents that match the query or prompt submitted. It then layers in semantic/vector search to expand results to relevant, related documents that could also match the query.
The addition of AI enhances traditional keyword-focused approaches, particularly in the areas of personalization and predictive search, by allowing the system to understand user behavior patterns and create “digital twins.” It can learn from one user’s successful interactions to improve results for similar users.
User Behavior
By capturing signal data on every user’s action, modern search platforms can determine intent. And by accounting for personal data (including geo-location), the platform can match a query to mapped content and retrieve the most relevant results.
Machine Learning
Coveo adds an additional, proprietary layer of relevance into the traditional RAG methodology, adding in an additional R. AI retrieves the most pertinent results within an enterprises’ unified index, and then from that selection, the most relevant chunks of information are selected to then be fed to a generative model for output. With Coveo’s fully managed Relevance Generative Answering, enterprises can harness RAG as a Service to embed accurate, secure generative answering throughout their digital experience.
In addition to Relevance Generative Answering, Coveo also offers a deep suite of enterprise-grade ML models that streamline and enhance the digital experience across all touchpoints.
