Differential Analysis of Age, Gender, Race, Sentiment, and Emotion in Substance Use Discourse on Twitter During the COVID-19 Pandemic: A Natural Language Processing Approach

Differential Analysis of Age, Gender, Race, Sentiment, and Emotion in Substance Use Discourse on Twitter During the COVID-19 Pandemic: A Natural Language Processing Approach

Recent advancements in NLP have addressed these challenges by facilitating tasks such as health information retrieval and extraction, text summarization, sentiment and emotion analysis, and the construction of medical ontologies and knowledge graphs. For instance, studies have demonstrated the utility of NLP in analyzing social media data to monitor public health trends, such as SU and mental health discussions during crises [20].

Natural Language Processing for Identification of Hospitalized People Who Use Drugs: Cohort Study

Natural Language Processing for Identification of Hospitalized People Who Use Drugs: Cohort Study

NLP has the potential to uncover hospital encounters with PWUD that may have previously been missed. Although NLP had greater PPV than diagnostic codes, its PPV remained low. We found that PWUD from racially and ethnically minoritized communities and those who had low income were more likely to be represented in the minimally documented cohort (ie, entry with NLP-only), rather than the maximally documented cohort.

Performance of Natural Language Processing versus International Classification of Diseases Codes in Building Registries for Patients With Fall Injury: Retrospective Analysis

Performance of Natural Language Processing versus International Classification of Diseases Codes in Building Registries for Patients With Fall Injury: Retrospective Analysis

To address these obstacles, natural language processing (NLP), which combines computational linguistics and deep learning models to process narrative data, can be used to automate the review process of clinical notes to detect falls [14]. Several studies have demonstrated the capability of supervised models to detect fall incidents, which have been documented in clinical notes [15-17].

Predicting Drug–Side Effect Relationships From Parametric Knowledge Embedded in Biomedical BERT Models: Methodological Study With a Natural Language Processing Approach

Predicting Drug–Side Effect Relationships From Parametric Knowledge Embedded in Biomedical BERT Models: Methodological Study With a Natural Language Processing Approach

Subsequently, ADR prediction methodologies using machine learning techniques have been developed [5-7], and with advances in natural language processing (NLP) techniques, attempts have been made to automatically extract and predict drug-side effect relationships from vast amounts of biomedical literature data [8-10].

Public Perception of the Brain-Computer Interface Based on a Decade of Data on X: Mixed Methods Study

Public Perception of the Brain-Computer Interface Based on a Decade of Data on X: Mixed Methods Study

Natural language processing (NLP) tools are instrumental in analyzing social media content, offering deeper insights into public perception. NLP methods enable the analysis of public sentiment toward specific topics, the detection of emerging trends, and the identification of demographic groups participating in these discussions. These tools have been extensively used to assess public acceptance of vaccines [19,20], guide economic investments [21], evaluate innovative products [22,23], and more.
