Construction of a Personal Experience Tweet Corpus for Health Surveillance

Keyuan Jiang, Ricardo Calix, Matrika Gupta
2016 Proceedings of the 15th Workshop on Biomedical Natural Language Processing  
Studies have shown that Twitter can be used for health surveillance, and personal experience tweets (PETs) are an important source of information for health surveillance.  ...  To mine Twitter data requires a relatively balanced corpus and it is challenging to construct such a corpus due to the labor-intensive annotation tasks of large data sets.  ...  This work was supported in part by the National Institutes of Health grant 1R15LM011999-01.  ...

SmokEng: Towards Fine-grained Classification of Tobacco-related Social Media Text [article]

Kartikey Pant, Venkata Himakar Yanamandra, Alok Debnath, Radhika Mamidi
2019 arXiv   pre-print
In this paper, we create a dataset of 3144 tweets, which are selected based on the presence of colloquial slang related to smoking and analyze it based on the semantics of the tweet.  ...  Contemporary datasets on tobacco consumption focus on one of two topics, either public health mentions and disease surveillance, or sentiment analysis on topical tobacco products and services.  ...  Our schema for categorization targets posts on public health as much as tobacco related products, therefore allowing us to know the number and type of tweets used in public health surveillance for the  ...

Aditya Joshi, Ross Sparks, Sarvnaz Karimi, Sheng-Lun Jason Yan, Abrar Ahmad Chughtai, Cecile Paris, C. Raina MacIntyre, Eric Forgoston
2020 PLoS ONE  
We experiment with two variations of an existing surveillance architecture: the first aggregates tweets related to different symptoms together, while the second considers tweets about each symptom separately  ...  We demonstrate the value of social media for automated surveillance of infectious diseases such as the West Africa Ebola epidemic.  ...  Personal health mention classification: This step is necessary because a tweet containing a symptom word may not be the report of a symptom.  ...
