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.

About

TILDE (Term Independent Likelihood moDEl) is a passage re-ranking and expansion framework built on BERT, designed to enhance retrieval performance by combining sparse term matching with deep contextual representations. The original TILDE model pre-computes term weights across the entire BERT vocabulary, which can lead to large index sizes. To address this, TILDEv2 introduces a more efficient approach by computing term weights only for terms present in expanded passages, resulting in indexes that are 99% smaller than those of the original TILDE. This efficiency is achieved by leveraging TILDE as a passage expansion model, where passages are expanded using top-k terms (e.g., top 200) to enrich their content. It provides scripts for indexing collections, re-ranking BM25 results, and training models using datasets like MS MARCO.
