Disease Classification from Clinical Text Records
Build a machine learning model to classify diseases based on clinical reports using advanced natural language processing (NLP) techniques.Hospitals generate massive amounts of textual data daily — including doctor’s notes, discharge summaries, pathology reports, and radiology interpretations. Manually reviewing this data for disease classification is time-consuming and error-prone. Clinical text mining with machine learning enables automated understanding and classification of medical records, allowing faster diagnosis support, better record-keeping, and improved clinical decision support systems. Handling medical text also presents unique challenges like abbreviations, misspellings, and complex terminologies, making this a rich domain for NLP applications.
Using datasets containing anonymized clinical texts labeled with disease categories, machine learning models like Support Vector Machines, BERT transformers, or CNN-based text classifiers can predict associated diseases. Preprocessing involves tokenization, removing medical stopwords, abbreviation expansion, and named entity recognition (NER). Fine-tuning transformer models like BioBERT or ClinicalBERT further enhances classification accuracy by capturing domain-specific medical language patterns.

Advanced Portfolio Project
Showcase skills in healthcare-specific NLP, text classification modeling, and transformer-based deep learning models — a growing tech field.
Start by collecting anonymized clinical notes labeled with disease categories. Preprocessing steps like text normalization, medical abbreviation expansion, stopword removal, and tokenization are applied. Machine learning models like TF-IDF+SVM, CNNs, LSTM classifiers, or transformer-based models (BioBERT, ClinicalBERT) are trained to map clinical text inputs to disease classes. Fine-tuning and domain-specific embeddings significantly improve model performance in healthcare contexts.
- Collect clinical datasets like MIMIC-III discharge summaries, n2c2 datasets, or Kaggle clinical notes collections.
- Preprocess text data: clean, tokenize, handle abbreviations, create embeddings (Word2Vec, BioWordVec), or fine-tune BERT models.
- Train classification models to predict diseases like diabetes, heart failure, COPD, infections based on clinical text inputs.
- Evaluate models using F1-score, precision, recall, and AUC-ROC, ensuring reliable disease classification with minimal false negatives.
- Deploy a simple web app where clinical texts can be entered to get instant disease classification predictions.
