About

ColBERT is a fast and accurate retrieval model, enabling scalable BERT-based search over large text collections in tens of milliseconds. It relies on fine-grained contextual late interaction: it encodes each passage into a matrix of token-level embeddings. At search time, it embeds every query into another matrix and efficiently finds passages that contextually match the query using scalable vector-similarity (MaxSim) operators. These rich interactions allow ColBERT to surpass the quality of single-vector representation models while scaling efficiently to large corpora. The toolkit includes components for retrieval, reranking, evaluation, and response analysis, facilitating end-to-end workflows. ColBERT integrates with Pyserini for retrieval and provides integrated evaluation for multi-stage pipelines. It also includes a module for detailed analysis of input prompts and LLM responses, addressing reliability concerns with LLM APIs and non-deterministic behavior in Mixture-of-Experts.

About

T-NEX Chatbot is a company knowledge assistant tailored to answer recurring questions from approved business content. It can retrieve maintained answers and show their recorded source references, or add a separately scoped retrieval-augmented generation (RAG) function that composes responses from relevant document passages. The solution can include an interface for authorised staff to create, edit and categorise knowledge entries, with source documents and ownership maintained alongside answers. It is designed for internal employee questions or defined customer-service information, such as work instructions, internal processes and service offerings. Project setup can define content permissions, treatment of unanswered questions, human handover, and evaluation against a question set before expanding sources or users. The language model is optional; data, access and conversation handling are tailored to the use case.
