Social Media Mining for Health Applications (SMM4H) Workshop & Shared Task 2018

(For the Shared Task, please follow this link…)


*** Proceedings on ACL anthology is now available here ***

The total number of users of social media continues to grow worldwide, resulting in the generation of vast amounts of data. Popular social networking sites such as Facebook, Twitter and Instagram dominate this sphere. According to estimates, 500 million tweets and 4.3 billion Facebook messages are posted every day.1 The latest Pew Research Report 1, nearly half of adults worldwide and two-thirds of all American adults (65%) use social networking. The report states that of the total users, 26% have discussed health information, and, of those, 30% changed behavior based on this information and 42% discussed current medical conditions. Advances in automated data processing, machine learning and NLP present the possibility of utilizing this massive data source for biomedical and public health applications, if researchers address the methodological challenges unique to this media.

This workshop aims to provide a forum for the ACL community members to present and discuss NLP advances specific to social media use in the particularly challenging area of health applications, following on the success of a session and accompanying Workshop on the topic that was hosted at the Pacific Symposium in Biocomputing (PSB) in 2016 and the AMIA Annual Conference in 2017. The workshop seeks to attract researchers interested in automatic methods for the collection, extraction, representation, analysis, and validation of social media data for health informatics. It serves as a unique forum to discuss novel approaches to text and data mining methods that are applicable to social media data and may prove invaluable for health monitoring and surveillance.

Although social media text mining research for health applications is still very much its infancy, the domain has seen a surge in interest in recent years. Numerous studies have been published of late in this realm, including studies on pharmacovigilance,3 identifying user behavioral patterns patterns,4 identifying user social circles with common experiences (like drug abuse),5 monitoring malpractice,6 and tracking infectious/viral disease spread.7,8 Population/public health topics are most commonly addressed, although different social networks maybe suitable for specific targeted tasks. For example, while Twitter data has been utilized for surveillance and content analysis, a significant portion of research using Facebook has focused on communication rather than lexical content processing.9,10 For health monitoring and surveillance research from social media, the most common topic has been influenza surveillance.11,12 From the perspective of informatics and NLP, proposed techniques have typically been in the areas of data collection (e.g., keywords and queries),13,14 text classification,15,16 and information extraction.17 While innovative approaches have been proposed, there is still a lot of progress to be made in this domain.

Effective utilization of the health-related knowledge contained in social media will require the joint effort by the research community, and the bringing together of researchers from distinct fields including NLP, machine learning, data science, biomedical informatics, medicine, pharmacology and public health. The knowledge gaps among researchers in these communities need to be reduced by community sharing of data and the development of novel applied systems. Our workshop attempts to achieve precisely these goals and appeal to researchers applying NLP methods in those domain areas and that might not typically consider ACL/EMNLP/NAACL. Topics of interest include, but are not limited to:

  • Methods for the automatic detection and extraction of health-related concept mentions in social media
  • Mapping of health-related mentions in social media to standardized vocabularies
  • Deriving health-related trends from social media
  • Information retrieval methods for obtaining relevant social media data
  • Geographic or demographic data inference from social media discourse
  • Virus spread monitoring using social media
  • Mining health-related discussions in social media
  • Drug abuse and alcoholism incidence monitoring through social media
  • Disease incidence studies using social media
  • Sentinel event detection using social media
  • Semantic methods in social media analysis
  • Classifying health-related messages in social media
  • Automatic analysis of social media messages for disease surveillance and patient education
  • Methods for validation of social-media derived hypothesis and datasets.
