Comparing Information Needs of Users with Different Personalities in Public Health Emergencies
[Objective]This paper explores the relationship between personalities and information needs.[Methods]First,we constructed a personality classification model based on linguistic and behavioural characteristics.Then,we utilized key phrase extraction method,Jaccard text clustering,and ERG theory for mining information needs.Finally,we used a one-way analysis of variance and logistic regression analysis to examine the relationship between the public's personalities and information needs.[Results]Public information needs encompass nine main themes:medical resources,prevention,symptoms,diagnosis and treatment,public symptom emotion sharing,emotional support,disease awareness,social impact,and epidemic development.We categorized the themes into three types:survival information needs,relational information needs,and growth information needs.Survival information needs were positively correlated with conscientiousness;relational information needs were positively related to extraversion and negatively related to neuroticism;growth information needs were positively related to neuroticism and agreeableness.[Limitations]This study does not consider the dynamic nature of information needs.Future studies could analyze the information needs at different stages of public health emergencies.[Conclusions]This paper can help government departments understand the public's information needs and conduct targeted intelligent information disclosure and risk management.
