What is the course

What is the Text Preprocessing Techniques programme?

A practical, outcome-focused training programme designed to help teams build knowledge, apply tools and improve performance in real work situations.

The programme gives participants a structured approach to profiling text, removing noise, standardising formats, handling common text variations and preparing cleaner inputs for downstream NLP tasks.

UnderstandKey concepts and best practices

ApplyTools and techniques in real situations

ImproveTeam performance and business outcomes

Is this right for your team

Is this built for your team?

This course is ideal for many organisations, but may not be the best fit for every situation. Here’s a quick guide to help you decide.

Ideal for teams who:

Want to understand how text is processed and represented in NLP systems
Need practical knowledge of tokenization techniques and word embedding methods
Are developing chatbots, text classification tools, or other language-based applications
Want to strengthen their foundational NLP skills through private, tailored corporate training

Another course may be better if:

You are looking for a public, open-enrolment course
You need a highly technical or specialist certification
Your team is not yet ready for this level of training
You are primarily looking for consultancy rather than training

?Not sure this is the right course?Talk to our team for a quick, no-obligation discussion. We’ll help you find the best solution for your goals.Request a Consultation Customised Training

Real business impact

Which workplace issues does this course fix?

Turn common challenges into opportunities. This course helps address the real issues teams face in today’s workplace.

Inconsistent text formatsStandardise casing, spacing, punctuation and formatting so similar text follows consistent rules.

Too much noise in raw textRemove or manage irrelevant characters, markup, boilerplate and other noise that can distort analysis.

Cleaning choices are made inconsistentlyUse explicit rules for handling punctuation, numbers, URLs, contractions and other text variations.

Over-cleaning damages useful informationRecognise when aggressive cleaning can remove context, meaning, domain terms or other signals needed for the task.

Poor visibility into text-data qualityProfile datasets, inspect recurring problems and document preprocessing decisions before downstream analysis.

Preprocessing does not match the NLP taskChoose preprocessing steps according to the task, language characteristics and intended model or analysis.

Tangible results

What outcomes will participants achieve?

Practical learning. Measurable impact. Participants leave with the skills, confidence and tools to make a real difference at work.

Better text-data qualityInspect raw text and identify the quality issues that should be addressed before downstream NLP work.

More consistent preprocessing decisionsApply repeatable rules for cleaning, normalising and standardising text while retaining task-relevant information.

Better preparation for NLP workflowsPrepare text for tokenisation, feature creation, modelling or analysis with clearer data and process requirements.

A documented preprocessing workflowRecord preprocessing steps, assumptions and exceptions so teams can reproduce and review the workflow.

More reliable downstream analysisReduce avoidable data inconsistencies that can affect NLP analysis, reporting and model development.

Course objectives

By the end of this course, participants will be able to:

Explain why preprocessing matters in an NLP workflow and how it affects downstream analysis
Profile a text dataset and identify common quality, formatting and consistency problems
Apply cleaning steps for whitespace, casing, punctuation, markup, URLs, numbers and other common noise
Choose appropriate normalisation steps for a defined text-processing task
Apply tokenisation and text segmentation appropriately for the intended NLP workflow
Use task-aware approaches to stop-word handling, stemming and lemmatisation where appropriate
Prepare cleaned text for downstream feature extraction or NLP analysis
Validate preprocessing results using before-and-after comparisons and quality checks
Recognise when preprocessing can remove useful meaning, introduce bias or create inconsistent results
Document preprocessing rules, assumptions, exclusions and exceptions for review
Communicate preprocessing decisions clearly to analysts, developers and other stakeholders
Build a practical preprocessing checklist for recurring text-data workflows

A practical, step-by-step approach

The 2-day learning journey

A structured, hands-on journey designed to build knowledge, apply skills and create real momentum for change.

1InspectProfile raw text and identify the sources of noise, inconsistency and missing structure.

2CleanRemove unnecessary characters, markup and formatting noise while preserving useful information.

3NormaliseApply consistent rules for casing, spacing, punctuation and other recurring variations.

4TransformPrepare text for realistic business scenarios and evaluate suitable preprocessing approaches.

5ValidateCompare before-and-after results, test consistency and document the final preprocessing workflow.

Detailed and practical

Inside the curriculum

Eight focused modules covering text quality, cleaning, normalisation, tokenisation, linguistic processing and validation.

2Cleaning Raw TextHandle whitespace, punctuation, markup, URLs, numbers, special characters and other common sources of noise.

6Normalisation and StandardisationApply consistent casing, spacing, spelling and formatting rules while protecting task-relevant information.

3Tokenisation and Text SegmentationPrepare text for tokenisation and sentence segmentation in the intended NLP workflow.

7Linguistic Preprocessing ChoicesUse stop-word handling, stemming and lemmatisation when appropriate for the task.

4Task-Aware Preprocessing and Feature PreparationChoose preprocessing steps that support classification, search, extraction, sentiment or other downstream tasks.

8Building and Validating a Preprocessing WorkflowSequence preprocessing steps, check outputs, document rules and identify next steps for the text pipeline
