The Crown Jewel of the Formula One Race Circuit, backdrop of the successful Hollywood Film “Crazy Rich Asian” and the honorable host of the Memorable North Korea-United States Summit, Singapore’s ability to position herself as a neutral yet vibrant destination has led to hordes of visitors setting foot onto her sunny shores. It is no surprise that the tourism sector has been developing into a growth engine for Singapore’s economy. For 2017, Singapore’s tourism sectors attained records highs in both tourists’ arrivals and spendingAccording to the data released by Singapore Tourism Board, the number of arrivals increased by 6.2 per cent to $17.4 million, while tourism receipts increased by 3.9 per cent to $26.8 million. The increasing affordability of travel, with the prevalence of low-cost carriers globally, as contribute to the opportunistic trend.
 
 
Time series data has always played an important role in understanding and evaluating past behaviours. The usage of time-series information has allowed companies and organizations to tune their operations instead of simply improving by trial and error. Time series data have also been used to evaluate whether an organization has grown throughout the years of operation. The analysis techniques for time-bound data help to describe and explore insights, while predicting the future outcomes such as revenues and profits.
 
 
 
This category of data analysis is not only constrained to the business world. A country's economic data is also a rich pool of information that can be analysed for insights. One of the important example measures that can allow us to get a glimpse would be the Consumer Price Index (CPI). Using this easily available measure, we can explore living standards of a country's citizens by understanding the factors affecting their day-to-day lives.
 
 
 
=== Use Case - Consumer Price Index ===
 
 
 
The Consumer Price Index (CPI), is a critical indicator to assess a country's consumer price inflation. To profile the weighted average price changes for households' cost of living, Singapore's CPI adopts a fixed basket of residents' commonly consumption goods and services. About 6,600 brands/varieties from 4,200 outlets are selected in the 2014-based CPI (the dataset for our study). At basket level, the composition of goods and services can be categorized into 10 major divisions, which are listed below:
 
Food, Clothing & Footwear, Housing & Utilities, Household Durables And Services, Health Care,
 
 
 
  Transport, Communication, Recreation & Culture, Education, Miscellaneous Goods & Services
 
 
 
[[Image:SG_2014_BASED_CPI.png|500px|thumb|right|Figure 1: 2014 CPI Basket Items from Singstat<ref name="singstat">Department of Statistics Singapore. [http://www.singstat.gov.sg/educational-corner/faq-on-CPI], "FAQ on Consumer Price Index (CPI)", Retrieved on 30 November 2017</ref>]]
 
To construct the CPI, two main types of data are required - the sample price data of the good or service, and the weighting data to represent the proportion of different categories' expenditure. The price data is gathered through a combination of data collection modes, while the frequency of price collection depends on the price behavior of the item. The weighting data is derived from the expenditure values collected in the Household Expenditure Survey,  the latest one came from HES 2012/13, updated to 2014 values by taking into account price changes between 2012/13 and 2014.
 
 
 
As a Price index, CPI can also be affected by other types of costs in Singapore. Indicators like COE Bidding Price<ref name="COE">Yeap, R.

These data sources are also acceptable within the proposed system design within certain format restrictions.

During our personal data analysis research and experiences, we discovered a lack of freely available analysis tools that can help us optimize the parameter settings of time-series models. The result is a large amount of time and effort utilized to enter in different combinations of parameters and waiting for the models to be trained. The time series system that we have in mind would need to help us estimate the model's accuracy rates automatically while we perform our data analyses, so we can simply choose the best models for comparison.

The ability of the analysts to grapple the data and transform the insights into actionable business decision will see their businesses flourishes.
  
Our team would also like to create exploratory and predictive models, which showcase these complex time-related trends of Singapore's CPI throughout the years (1990-2017) for different categories.

Even though Singapore is a relatively young country, it is able to provide rich data to help us explore these interesting observations. This is also in part due to the government initiative of 'SmartNation.sg'.

Background

The Crown Jewel of the Formula One Race Circuit, backdrop of the successful Hollywood Film “Crazy Rich Asian” and the honorable host of the Memorable North Korea-United States Summit, Singapore’s ability to position herself as a neutral yet vibrant destination has led to hordes of visitors setting foot onto her sunny shores. It is no surprise that the tourism sector has been developing into a growth engine for Singapore’s economy. For 2017, Singapore’s tourism sectors attained records highs in both tourists’ arrivals and spending. According to the data released by Singapore Tourism Board, the number of arrivals increased by 6.2 per cent to $17.4 million, while tourism receipts increased by 3.9 per cent to $26.8 million. The increasing affordability of travel, with the prevalence of low-cost carriers globally, as contribute to the opportunistic trend.

Motivation

During our exploratory analysis on the data comprising of the tourism arrival into Singapore, we noticed that the arrival patterns of tourists from respective countries at heterogenous. A keen understanding to the unique of arrival patterns can reveal the travel preference which is essential for businesses to attract more tourism receipts to boost their business revenue. The ability of the analysts to grapple the data and transform the insights into actionable business decision will see their businesses flourishes.

With the recent completion of Marina Cruise Centre and ongoing construction of Jewel Changi Airport, the tourism receipts are expected to continue to grow steady for the next decade, barring any black swans.

Objectives

We aim to build an interactive platform to illustrate the trends and seasonality within given time-series data on Singapore tourism sector. Users can have a better understanding of the Singapore tourism situation over the last ten years.

Through this project, we hope that the tourism industry business, especially the small and medium business (check with the SME contribution to Singapore economy or tourism industry) can make optimal marketing solutions and business decision. We attempt to create the platform that assist the business owners and analysts to detect some useful insights from the relationship between travelling revenue and expenditure to promote the economic growth.


  • The platform can give us the overview on the visitors’ arrivals pattern by country, age and different transportation methods.
  • It also provides the geographic map to illustrate the visitor density among different countries.
  • Tourism demand forecasting


Data Source

The Consumer Price Index (CPI) data is extracted from data.gov.sg[1] in a monthly format which reveals the figures from January 1961 to August 2017, while the index reference period is 2014. The data has an overall index representing changes in the price level of the whole basket with all items considered, and can also be drilled down to sub-indices and sub-sub-indices for different categories and sub-categories of goods and services. For our system analysis, we plan to use filtered data from 1990 onwards.

Methodology

Exploratory Analysis

We will explore the different trends of time-series data provided by the various economic data sets (Period cyclicity and seasonality). Different interactions of identified attributes might provide certain data insights that we can use for our analysis.

Explanatory Analysis

Relationships between our data will be explained based on our understanding of possible real-world events or causes. Using our CPI use-case as an example, the difference in CPI between the months of June and December can be explained as a result of the holiday seasons causing an increase of demand for clothing in December.

Predictive Analysis

We can use analytics techniques such as Exponential Smoothing and ARIMA to predict future trends of our time-series data, due to the data's cyclical and seasonal nature.

Application

The proposed system would have three major functions:
