Understanding cancer symptom management using Amazon reviews: a human-annotated corpus
ABSTRACT
Background:
Complementary therapies are being increasingly used by cancer patients. As a channel for customers to share their feelings, outcomes, ideas, and perceived knowledge about the products purchased from e-commerce platforms, Amazon online reviews are a valuable real-world data source for health care studies.
Objective:
In this study, we aim to highlight the potential of using Amazon consumer reviews in mining the outcomes of cancer symptom management, provide a freely accessible corpus, and develop natural language processing (NLP) baseline models to demonstrate the usability of the annotated dataset.
Methods:
We preprocessed the Amazon review dataset and conducted content analysis. We then designed an annotation guideline, annotated 159 reviews, and developed baseline models based on deep learning and large language model (LLM) for name entity recognition and text classification tasks.
Results:
The annotation labels were designed to capture cancer types, indicated symptoms, and symptom management outcomes. The resulting annotation corpus contains 2,067 labels from 159 Amazon reviews. It’s publicly accessible, together with the annotation guideline through the Open Health Natural Language Processing (OHNLP) Github. Our baseline model, bert-base-cased, achieved highest weighted average F1, i.e., 66.92%, for NER, and LLM gpt4-1106-preview-chat achieved the highest F1 for text classification tasks, i.e., 66.67% for “Harmful outcome”, 88.46% for “Favorable outcome” and 73.33% for “Ambiguous outcome”.
Conclusions:
Results showed the potential of using Amazon reviews in mining the outcomes of cancer symptom management. The annotation corpus and baseline models provide a foundation for future enhanced methodology development to facilitate cancer symptom management in cancer patients using Amazon consumer reviews.
