Are your teams now posing potentially confidential questions to consumer tools such as Bard and ChatGPT, relying on their responses? Or have you noticed a slowdown in your research process due to information overload, hindering the ability to swiftly identify critical findings?
Whatever the reason, you’ve acknowledged the pressing need for a dedicated AI-based chat application for your teams. If this scenario resonates with you, allow us to guide you to the next level.
In addition to these requirements, any application striving to thrive in today’s world must meet a minimum standard, which is already set quite high, for user experience (UX), performance, and availability.
Before we attempt to meet these requirements, let’s pause to understand the strengths and weaknesses of LLMs. LLMs essentially rely on statistical probabilities derived from extensive training data, determining the likelihood of word sequences within sentences. Consequently, if the training data lacks an answer to a query, the model resorts to generating sentences based solely on these statistics, resulting in nonsensical outputs or “hallucinations.”
Moreover, if the training data contains inherent biases, the generated answers are prone to reflecting those biases. Additionally, since the model is trained on data without preserving its sources, it lacks the technical capability to provide source links for generated responses.
Given that the training data for LLMs comprises essentially all text accessible on the internet, maintaining an LLM to incorporate the latest information consistently is an exceedingly costly endeavor.
Nevertheless, LLMs excel in summarizing text, generating content, and interpreting human language.
At SciBite, through persistent efforts, our teams conducted rigorous experiments involving various flavors of LLMs, vector-based retrieval, ontologies-based retrieval, and hybrid approaches. We also integrated ontologies enrichment at different stages of the question-answer flow. The culmination of these efforts has resulted in an AI chat application that fulfills all requirements.
As an advantage, the application renders the answer-generation process entirely transparent. It utilizes ontologies to provide clarity on how and why results were identified. It maintains not only a list of relevant documents but also segments of the documents utilized for answer generation, along with an explanation of why it considers them to contain the answers. This stands in contrast to any other system that operates as a black box and lacks the ability to offer this level of transparency.
Use of ontologies also facilitates structuring the natural language question, ensuring reproducibility, and allowing saving or approval.
In the next part, I will explore further how utilization of ontologies for enrichment at various stages addresses gaps in a RAG application and enhances its accuracy, reliability, and efficiency.
