2. How to use big data in tourism forecasting
Predictive analytics gives marketing professionals more
insight into customer preferences, which can be used to
understand tourists better and improve tourism
firms/destination competitiveness
Data mining techniques can be exploited to help
tourism forecasting with big data
Differentiate big data from traditional tourism
forecasting techniques
3. How to use big data in tourism forecasting
Making sure that tourism business benefits are derived from big
data. It is important to set specific business goals rather than
just dealing with the big data itself.
Visualizing the big data with a view to understanding the nature
and characteristics of the data.
Structuring the big data according to the requirements of
traditional forecasting techniques
4. How to use big data in tourism forecasting
In order to apply traditional forecasting method to big data, we
have to simplify the structured big data
One of the solutions is to shrink the big data and get the most important
information in a suitable format that can be easily applied to the traditional
forecasting models.
Mixed frequency model with big data
Using a novel forecasting method with the mixed-data sampling (MIDAS)
approach to fully utilize the high frequency search engine data
Factor model and forecasting combination
The best way to forecast the low frequency series (such as tourism
demand) using high frequency data is to combine the shrinkage method
with the mixed frequency models.

6. Challenges
Can the patterns that emerged from big data analysis or forecasting be
generalized?
The second challenge is to find the right talents capable of both
working with the new forecasting technologies and interpreting the
data to find meaningful business insights.
Third is to overcome the obstacle of data access and connectivity,
which requires the right platforms to aggregate and manage the big
data.
The fourth problem is how to find new ways of leveraging big data in
tourism forecasting.
