Calculate the average sentiment score for each feedback category, such as room cleanliness or customer service, and visualize the results using a bar chart to highlight areas with the lowest scores.

Perform a cohort analysis to compare feedback patterns across different customer segments, such as business travelers or families, to identify if certain groups are more dissatisfied than others.

Use sequence analysis to identify common complaint patterns over time, such as issues reported during check-in leading to dissatisfaction with room quality, and visualize these patterns using a flow diagram.

Apply association rule mining to identify frequently co-occurring feedback themes, such as 'poor Wi-Fi' and 'slow check-in process', to uncover hidden relationships between different service aspects.
