Uncovering the Hidden Gems of Psoriasis Literature: An Neural Language Model-Assisted Interactive Web Tool

Abstract

AbstractBACKGROUNDThe comprehensive data on psoriasis research are numerous and complex, making it difficult to retrieve and classify manually. The ability to quickly mine literature based on various fine topics using deep learning natural language processing technology to assess research topics and trends in the field of psoriasis disease will have a significant impact on doctors’ research and patients’ health educationMETHODA neural topic model is used to identify fine topics of psoriasis literature published in the PubMed database from 2000 to 2021. Dermatologists evaluate the algorithm-modeled topics, summarize the categories into the most effective topics, and perform linear trend model analysis. The accurate classified topics are presented on an interactive web page to identify research hotspots and trends.RESULTSAt the categorical level, after review by clinicians, 158 out of 160 generated topics were found effective and categorized into 8 groups: Therapeutic methods (34.34%), pathological mechanisms (23.46%), comorbidity (20.04%), Clinical manifestations and differential diagnosis (12.77%), experimental modalities and methods (3.22%), diagnostic tools (2.99%), epidemiology (1.75%), and meetings/guidelines (1.43%). A linear regression model had good accuracy (MSE=0.252602, SSE=42.1845) and strong correlation (R-Squared=0.898009). ANOVA results showed that categories significantly impacted the model (p<=0.05), with experimental modalities and methods having the strongest relationship with year, and clinical manifestations and differential diagnosis having the weakest. An interactive web tool (https://psknlr.github.io) facilitates quick retrieval of titles, journals, and abstracts in different categories, as well as browsing literature information under specific topics and accessing corresponding article pages for professional knowledge on psoriasis.CONCLUSIONSThe neural topic model and interactive web tool can effectively identify the research hotspots and trends in psoriasis literature, assisting clinicians and patients in retrieving and comparing pertinent topics and research accomplishments of various years.
