The real words
What text data is, and why visualise it
Text dataInformation expressed through words, sentences or documents. It carries information, but its structure is not immediately visible.
The deck gives four reasons to visualise it, and they make a clean four-mark answer.
- Understanding the high-level themes, topics and sentiment
- Grouping similar documents without reading each one
- Comparing the language, style or content of different authors
- Correlating relationships between concepts, entities or keywords
