Title of thesis: Health/Clinical Text Processing in Social Media using NLP
The use of social media has made it a valuable source of information for various domains, including healthcare. However, the unstructured nature of social media data makes collecting relevant information for healthcare studies difficult. Social media sites such as Twitter, Facebook, and Instagram have been popular in Indonesia for discussing health-related concerns such as illness outbreaks, drug usage, and healthcare experiences.
The goal of this PhD thesis is to use NLP techniques to address the issues of health and clinical text processing in non-english languange, in particular using Indonesian languange. The goal of this research is to create and test an NLP pipeline for analysing Indonesian social media data relevant to health and clinical issues. To extract meaningful information from the text, the pipeline will use multiple NLP techniques such as tokenization, part-of-speech tagging, named entity identification, and sentiment analysis using CLAMP method (Soysal et al 2018).
The second objective is to apply the developed pipeline to a large dataset of Indonesian social media posts related to health and clinical issues. The dataset will be compiled from tweets with the hashtags #longcovid and #covid and will include a variety of COVID-related health concerns. The processed data will subsequently be used for a variety of purposes, including illness surveillance, detection of adverse drug events, and study of sentiment analysis for COVID-19.
