How do I start an NLP project?

Define one user decision, output, error cost and baseline first. Then establish data rights and an evaluation set before selecting a model.

What is a good first NLP project?

A bounded, frequent and reviewable task such as routing messages or extracting defined fields is usually easier to evaluate than open-ended generation.

How much NLP training data is needed?

There is no universal number. Requirements depend on task variability, labels, languages, pretrained-model fit and error costs. Use pilot learning curves and slice evaluation.

Should an NLP project use rules or machine learning?

Start with the simplest adequate baseline. Rules work for stable explicit patterns; machine learning helps when variation and context exceed manageable rules.

How should NLP data be split?

Group duplicates, threads, templates and related sources before splitting. Hold out sites, customers or time periods when those represent the required generalization.

When is an NLP model ready for production?

Only after representative quality, workflow value, privacy, security, latency, fallback, monitoring and ownership criteria pass in a controlled pilot.

What should be monitored after launch?

Monitor input and language shifts, task quality, unsupported outputs, corrections, latency, cost, incidents and the downstream business outcome.
