Text Mining: Links and Cirrus of Hong Kong Government’s Responses
The outbreak of SARS had a noticeable impact on Hong Kong. We attempted to analyse the government’s response to the challenges brought by the virus.The following Voyant visualisations will display word links associated with the government responses. The two Voyant visualisations in this subpage are known as:
- Cirrus
- Links
Information of what they consist of will be provided below the visualisations.
Using Voyant
In the “Cirrus”, the size of the words correspond to its frequency in the documents! You can decide the number of frequently-used terms shown in the visualization by dragging the “term” bar. You may also select the word cloud of the entire corpus or different documents in the ‘scale’ column.
In the “Links” analysis, you can find the interesting connections between words by zooming in, when you stop on one of them, the links between words will be more obvious! You can select keywords that you would like to investigate on the bottom left corner
You can click the picture to jump to the Voyant tool to learn more about the correlations between terms and try out more different tools!
Cirrus of Words Related to the Government’s Response to SARS
Description of the Cirrus
Responses of the government on SARS were mostly related to the medical aspect. The outbreak of pandemic peaked at March, and measures taken on SARS patients at that time are related to public resources in the hospitals, such as staff management.
Links of Words Related to the Government’s Response to SARS
Description of the Links
As a response, the government reserved fiscal resources for emergency usage. Words like “quarantine”, “isolation”, “tracing” and “contact”, demonstrate that the government took quarantine as a measure to prevent the public from being infected by the SARS patients. Hospitals had a strong relationship with control and infection. Thus, facilities were reserved for quarantine. Words like “Wales”, “Princess”, “Queen” and “8a” demonstrate the institutions for hospitalisation. Furthermore, the government traced close-contact personas to detect potential disease carriers. Also, the government prepared more protective equipment, like facemasks or PPE, to prevent people from being infected. Surgical masks, N95, were having a significant performance on it.
