LlamaIndex Consulting in Derry

Retrieval advice for Derry organisations, beginning with the artefact most projects skip. Before building anything you need a set of real questions with known correct answers — because without it, every subsequent decision about chunking, embedding and ranking is settled by whoever tried the most convincing example.

Why this comes up

The problem

Two approaches were compared by asking each a few questions, and the team picked the one that felt better that afternoon.

What you get

What we deliver

  • An evaluation set of genuine questions with verified answers and sources
  • Retrieval measured against it, so improvements are demonstrated not asserted
  • Document corpus assessed for what is actually answerable from it
  • Architecture chosen against your document types and question patterns
  • Cost and latency modelled at expected volume before building
  • A view on where retrieval will not help and something else is needed

LlamaIndex Consulting in Derry — common questions

Why build an evaluation set first?
Because it is the only way to know whether a change helped. Retrieval improvements are frequently trade-offs — better on one question type, worse on another — and hand-testing a few examples systematically favours whatever the tester happened to try.
How many questions do we need?
Fewer than people assume, provided they are representative. Fifty real questions covering the range users actually ask, with correct answers and the source that contains them, is enough to detect meaningful differences between approaches.
What if the answer is not in the documents?
Then no retrieval system will find it, and the honest finding is that the corpus is the problem. Organisations frequently discover the knowledge people ask for lives in individuals rather than documents, which is a different project entirely.
When is retrieval the wrong approach?
When questions need aggregation or reasoning across many documents rather than finding the right passage. Counting, comparing and trend questions are poorly served by retrieval, and pointing that out early avoids a system that disappoints on exactly those.
Do you work with businesses across County Londonderry?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Derry businesses do you usually work with?
Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
Do you cover the areas around Derry?
Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
