Conclusion from literature review Our literature review shows that, despite significant research in the areas of text mining and NLP, there is a strong dominance by supervised methods built on well-curated data that do not transfer well to practical scenarios. This is partially reflected by the number of industrial text mining/NLP studies that incorporated rule-based methods and the use of domain lexicons, except a few areas (e.g., the legal domain) where high quality curated resources are abundant. The majority of industrial studies also look at single and sometimes simplified tasks, but do not report a full process in an end-to-end fashion, particularly with a lack of details on how data heterogeneity and inconsistency is dealt with by their methods. Further, no prior work has focused on the healthcare domain. Our work will address these gaps.
