🌌 plexus-accelerator-ner-v3
plexus-accelerator-ner-v3 is a high-performance, multilingual Named Entity Recognition (NER) engine. It serves as the critical Triage and Accelerator Layer for the Plexus V4.2 Adaptive Intelligence Engine, a system designed to assist users with executive dysfunction and ADHD through proactive AI coaching.
🏗 System Role: The "Accelerator" Layer
In the Plexus V4.2 architecture, this model sits at Layer 1 (The Accelerator). Its primary goal is to resolve user intent with minimal computational overhead.
- Semantic Routing: Extracts entities (Project Names, Deadlines, Categories) to create anonymized intent templates.
- LLM Bypass: Allows the system to execute "Automatic Paths" (>98% confidence) without invoking expensive LLMs like GPT-4o, reducing latency by ~85%.
- Privacy-First: Operates as a "Data Sanitizer," ensuring that personally identifiable information (PII) is tokenized before being passed to cloud-based reasoning layers.

Entity Schema
The model is fine-tuned to recognize the following specialized labels:
B-PROJECT: Start of a project or goal name.B-TIME: Temporal constraints and deadlines.B-CATEGORY: Task classification (Work, Social, Health).B-URGENCY: Priority markers in natural language.
🛡 Ethical Considerations & Privacy
This model is built on the principle of Local-First AI. By performing NER locally, Plexus minimizes the surface area for data leaks. This is particularly critical for users tracking sensitive medical or professional data.
🔗 Project Context
This model is part of the Plexus Project, an initiative to democratize executive function support.
