- 11. Outline of work During my internship, I created two major projects that covered all the concepts of technology (1) HOTEL BOOKING ANALYSIS The purpose of this project was to analyse hotel booking data and gain insights into the factors that influence hotel booking cancellations. The data was collected from a publicly available dataset on Kaggle, and the analysis was performed using Python and its data analytics libraries. The project involved data cleaning and pre-processing, exploratory data analysis, and data visualization to gain insights into the patterns and trends in the data. The results of the analysis provide insights into the key factors that contribute to hotel booking cancellations and offer recommendations to hotel operators to reduce cancellations and optimize revenue.
- 12. Outline of work • Identify Relevant Data Sources: Hotel Booking Dataset from Kaggle • Collect Data and Store it in a Structured Manner • Perform Data Cleaning and Pre-processing • Exploratory Data Analysis B. Data Modelling and Analysis • Determine Relevant Variables and Features: Guest Demographics, Booking Details, Hotel Information, etc. • Choose Appropriate Modelling Techniques: Linear Regression, Random Forest Regression, etc. • Evaluation of Models: Mean Squared Error, R-Squared Value, etc. C. Results and Conclusion • Insights Gained from Analysis: Key Drivers of Booking Cancellations, Popular Booking Channels, etc. • Potential Business Applications: Improve Booking Experience, Optimize Hotel Inventory Management, etc.
- 13. Outline of work OBSERVATION 'Direct' and 'Online TA' are contributing the most in both types of hotels. Aviation segment should focus on increasing the bookings of 'City Hotel’.
- 14. Outline of work In conclusion, this project has successfully analysed the hotel booking dataset and provided insights into the factors that contribute to booking cancellations. The analysis revealed that the lead time between booking and arrival, the type of booking, and the deposit type were the most significant factors contributing to cancellations. Moreover, it was found that customers who book through online travel agencies are more likely to cancel their bookings than those who book directly through the hotel website. The results of this analysis can help hotel operators to optimize their booking processes, improve customer experience, and reduce cancellations, ultimately leading to improved revenue and profitability. Further research could be conducted to explore additional factors that may influence hotel booking cancellations and to develop predictive models that can help to forecast cancellations and adjust booking policies accordingly.
