ner-pk: named entity recognition for Pakistani news

A fine-tuned XLM-RoBERTa-large model that finds 20 kinds of entities in Pakistani news text: people, government bodies, political parties, laws, CNIC numbers, money and more.

Training data came from two LLM labellers with agreement filtering, plus synthetic pattern sentences, trained in two stages. A regex rules layer and a document-level consistency pass sit on top, and it ships as a CPU-ready command-line tool that reads text, JSONL or CoNLL.

    Smart EV Charging Station Planning

    Two linked problems on a Karachi road network. Kruskal with Union-Find builds a minimum spanning forest and repairs it after road failures; an exact 0/1 multiple-knapsack DP assigns charging requests to stations within capacity. About 340 automated tests and a Next.js results dashboard.

    API Incident Triage Expert System

    A rule-based "virtual SRE". You describe what's broken and answer a few yes/no questions; a forward-chaining engine with 60+ hand-written rules names the root cause, the failing layer, the fix and its reasoning.

    Smart Parking DFA Simulator

    An interactive deterministic finite automaton for a parking controller: each sensor event is an input symbol, with an animated state diagram, step-by-step trace and Mealy/Moore outputs.

Lab

Two projects you can run on this page.

Exhibit AEntity highlighter

Runs the project's rules layer and a small word list in your browser. The real system is the fine-tuned XLM-RoBERTa model.

Exhibit BKruskal + Union-Find

Roads are tried cheapest first. Solid roads join two separate groups; dashed ones would close a loop and are skipped.
