ABSTRACT
Based on internal database as big data of the Eximbank, 3,527 active customers
with the initial length of service more than 12 months, the method of data mining
is concerned, in which the mathematic methods of K-Means of cluster, Tree
Decision, and Association Analysis are applied. The findings show that
consumers’ characteristics using services at EXIMBANK are various, in which
staffs, directors as individual customers occupy a high proportion in total
customers. Based on descriptive statistics, there are eight main products, such as
VG (Visa Gold), VC (Visa Classis), MG (Master Gold), MS (Master Standard),
VP (Visa Platinum), VV (Viva Violet Card), VA (Visa Auto Card), and others are
concerned most by the customer, in which VG and VC are the two top cards used.
Directors are more interested in VG card, while staffs concern VC card. In
addition, using two cards, called the main card and the extra card, is popular. This
is a potential chance for the bank to develop cross-selling products, which the
product bundle strategies are packed into groups. Based on the method
Association Analysis, propobality of using two cards or three cards at the same
time of customers are derived. This finding basically supports the bank to address
cross-selling products of cards to customers. To do this, recommendations of the
strategies of bundle products are suggested in the thesis, together with
implementation plans

CHAPTER 1: INTRODUCTION
I.
RATIONALE OF RESEARCH
Rapid development of information technology in the banking industry has created a big
concern that the banks must think of how to explore internal data to serve competitive
strategies. In fact, currently, most banking institutions, insurances and financial services
are attempts to adopt a new approach toward data mining to the development and
innovation of services that they provide to customers. Like most other industries, big
data analytics are going to be a major change to support business units to generate
campaigns for a short term and long term strategies to attract more new customers, retain
existing ones and fight against the competitors.
Investing a big data system cause simulation that data mining is much concerned in the
banking industry, because it supports to extract valuable information form huge amounts
of data. Particularly it contributes into finding out consumer behavior and present a
market situation picture of a firm. However, it is not easy to explore big data of firms.
Data scientists developed quantitative methods as mathematic approaches, such as
descriptive and predictive analytics, etc.
Nowadays, banks have realized the importance of customer relation, this is one of
successful factors. However, challenges of how to retain most profitable customers and
to reduce a churn rate are problematic. To solve this problem, consumer behavior should
be investigated and analyzed, which big data are a worth resource and quite helpful to
measure and predict consumer behavior correctly. Therefore, the power of data is to
derive utility across various spheres of their functioning, product across selling,
regulatory compliance management, risk management, and customer service
management.
As we know, particularities of banks’ activities generate a huge amount of data from
unstructured data, such as transaction history, customer to the unstructured data such as
the customer’s activities on the website, or the mobile banking application on social
networks. However, how to explore big data available is the most problem. Although
there are not few banks who recognize that and want to turn the big data available to the
most effective weapon for the market competition, they are seemly facing problems of
new system, skills, and so on.
With changes in integration policies of Vietnam through information technology system,
together with fire competition, more and more banks in Vietnam have paid more
attention to investing a huge money for big data system and people capacity. For
example, EXIMBAK is one of the banks, who is willing to pay money to structure data
2
system very early. It realizes benefits of data warehouse to support business strategies.
In fact, the benefits of internal brought not the raise of the internal management
efficiency, but also help increase the competitive advantages, maximize profits.
Currently, the banks must be flexible for their plan toward activities of innovation, in
term of capturing needs of customers and improving satisfaction and retention of
customer. By the way, CRM is quite helpful and recognized for acquisition and retention
of customers. As a result, the bank can get more opportunism to make long lasting and
profitable relationships with customers.
To investigating big data system of the bank, Eximbank has offered a program of
building capacity for staffs, who are directly related to data analytics and business
development. In addition, the department of database is established to exploit internal
database, which the role of an employee is placed in the ecosystem talent development.
However, everything is seemly concerned and exploited more and more toward data
mining, predictive analytics on customer behavior.

RESEARCH METHODOLOGY
Data collection
Data used are extracted from data warehouse of the bank. Because of security requested,
this thesis is seriously asked to be confidential. Using information as well as findings of
this study is not convinced, it must be responsible for who going to use that.
Data pre-processing is taken into account of the data mining process, because it improves
the accuracy and efficiency of subsequent modeling (Han & Kamber, 2006). Activities
of data pre-processing techniques are data cleaning, data transformation, data integration
and data reduction, these are concerned, due to data quality.
The database used in the study is extracted from data warehouse of the bank, which the
period of study is 12 months, from January 1, 2019 to December 31, 2019. Accordingly,
the database selected has 130,000 rows, equivalent to 3,527 customers. This means one
individual customer has more transactions during study, so the rows are more than the
customer amount. As presented in table 1.1, 25 fields or variables are taken into account
of the current study. Each one has a defined measurement, such as nominal, continuous,
date, categorical.

Methods to analyze data
Data mining is one of tools concerned toward descriptive statistics. In addition,
clustering techniques is employed to cluster customers into groups, which it to satisfy
two main criteria: (i) each group or cluster is homogeneous; (ii) each group or cluster
should be different from other clusters. This method mainly gains customer
6
segmentation. In term of classification method, the cluster of K-means is employed to
segment customers (Khajvand & Tarokh, 2011).
Input variables recruited in the cluster method are generated by the RFM indicator, which
R as Recency, F as Frequency, M as Monetary are generated. Since segmentation is on
the basis of Recency – Frequency – Monetary (RFM), the selected features of data to
meet RFM is included last transaction date (purchased), count transaction (purchase)
and total monetary that customer took loan during one year and count item which refers
to variety of customer taken transaction. To count transaction, it is the frequency of
customer transactions. In data transformation, the data is transformed in a way that can
be exploited by data mining tools.
C&R Tree as “Classification and Regression Tree” is also employed to investigate
customer behavior in more detailed. It is supported to develop classification systems
toward prediction based on a set of decision rules. Application of this method known as
rule induction brings several advantages. Based on this the marketer can think and
develop campaigns to retain customers and stimulate their consumption.
Association Rules as the method of Association Analysis, it presents an association
based on antecedent and consequent. It means that once the antecedent is true, then the
consequent is also true. Association rules present a probabilistic rule and modify
probability of consequent happened exactly, given that the probability of “antecedent”
is truly happened.
Suppose there are two inputs of X and Y employed in the method. Results of Association
Analysis give indicators, which the confidence and the lift are concerned in this study.
The confidence is defined as the conditional probability to find in a group Y having
found X, while the lift presents whether the association between X and Y is positive or
not. With lift ≥ 1 it gives a message of positive association between X and Y, otherwise
negative association is happened.

CHAPTER 2: CONCEPTS CONCERNED AND ITS FRAMEWORK
I.
CONCEPTUAL FRAMEWORK
Service retention
Retaining current customers and returning them to loyalty has played an important role
to save and reduce business cost. To obtain this, currently banks have used a variety of
advanced analytical tools to find out customer behavior and grow customer relationships
for maximizing profitability. Because of the competitive market, most commercial banks
pay more attention to analytics on database available that determine habits of top
performers, rather than what drive customers, and looking forward to application of big
data in spheres like front office risk management to back office trade operations. Some
of them calls over in-person meetings to investigate necessary information.
In addition, to retain the customers, banks are wise to investigate a broad spectrum of
data and measure data points across multiple segments of clients. Once data are deeply
explored, the company can get higher efficiency with a low cost. In fact, many types of
costs can be accursed in the business unit, e.g. costs of advertising to entice new
customers, costs of a personal selling pitch to new prospects, costs of communication to
explain business procedure for new clients and dealing. These costs can be reduced if
the business units have a good approach on data mining. For example, banks in Vietnam
have a high investment on big data system to record customer behavior from different
channels.
Loyalty in retail banking: Customer loyalty is one of criteria that any company is
concerned very much. However, still some bankers have a little agreement among them
to what behaviors constitute customer loyalty and how best to stimulate these behaviors.
However it is not easy to earn loyalty, because of fierce competition. This is reason the
most bankers want to be typically of product-oriented programs. Still many retail bankers
are not clear of thinking of the customer loyalty with two distinct, e.g. customer
stratification and customer retention. As the following, classification of these two
definitions are presented.
Customer satisfaction: what the customer is expecting, she or he is fulfilled, which his
or his needs, wishes or desires on products or services are met. However, it is not
convinced to be sure guarantee of retention or loyalty (Szus & Tóth, 2008). Srivastava
& Gopalkrishnan (2015) used big data in Indian banks to analyze the customer
satisfaction measurement. Accordingly findings showed poor services and other issues
8
that customers complain. Based on that marketing strategies are suggested to Indian
banks.
Customer retention: Unlike customer satisfaction and customer loyalty, customer
retention is an ability to remain customer over time and measures a relationship between
the customer and the firm. Once customer is retained longer, expectation of loyalty is
possible (Jaiswal, et al., 2018). However, according to Kumar, et al. (2013), indicating
customer satisfaction offers only small portion of variance in loyalty, but not convince
much to enhance customer retentions.
Retail banks are often guilty of mistaking customer inertia for loyalty. Correct cognition
on customers can be on the four quadrants of behavior-attitude scale (Truly Loyal,
Accessible, Trapped, Higher Risk), also must be awareness of the differences between
the behaviors that customers display their attitudes toward the bank. Once the customer
is trapped, but not loyalty, they can be remained for a long term. But this customer can
leave any time once it realizes the bank in low esteem. As a result, to understand the
degree of loyalty gaps, the bankers need to know very well the characteristics of
customers as consumption behavior and how to connect between satisfaction and
retention. As argued by Szus & Tóth (2008), it is not easy to know that customer loyalty
can be possible to be displayed as customer retention.
Remaining good relationships between the customer and retail banking
Because of fire competition, retail banks have paid more attention to revamping loyalty
programs toward customer. This is strongly considered toward incorporating a reward
system into the bank’s plans. Currently, many retail banks offer a significant number of
potential rewards to promote and solidify customer loyalty. The banks develop a
relationship based on two-way street, which the customer will remain relationship only
once there is value in doing so. However, once the customers’ purchase volume is
increased and beneficial relationship gradually takes shape, the customers’ relationship
with banks is remained (Jaiswal, et al., 2018)
1. The concept of big data and its consideration in banking
There are many studies using big data to analyze customer consumption (Khajvand &
Tarokh, 2011), these studies mention that big data as the tool allow a business unit to
manipulate, create and manage huge data sets, also it is stored and required to support
the volume of data, characterized by variety, volume and velocity1.
Big data can be both structure and unstructured with the large volume of data. It records
activities designed in the system. If doing business, this data is recorded consumption

history of customers during period, it is enriched on a business a second-to second or
day-to-day basis by time. It will change our world completely and is not a passing fad
will a way. It is what organizations can use to investigate on business issues,
management issues or/and other sectors.
Banks internationally are beginning to harness the power of data in order to derive utility
across various spheres of their functioning, ranging from sentiment analysis, product
cross selling, regulatory compliances management, reputational risk management,
financial crime management and much more (Srivastava & Gopalkrishnan, 2015).
Big Data play an important role to extract the data value and support to obtain better
decisions. Then, the high cost of running time, which will make the problem difficult to
solve, can be avoided. Through these techniques, financial companies will have less risk
when predicting that customers will be successful in their payments. So more people can
get access to credit loans.
2. Big data in Banking and its contribution
Once the number of customer increases, this affects to a certain extent, the bank need to
think of providing quality. Practice shows that the analysis of existing data has simplified
the process of monitoring and assessing customers' credit banks and financial
institutions, based on large volumes of data such as information, dossiers personal and
other confidential information. But with the big data available, banks can exploit to
continuously monitor the behavior of the customer in real time, identify sources of data
required to collect service of offering solutions Justice. Evaluation process customer
records in real time will gradually boost operational efficiency and profitability, thereby
promoting further organizational development.
According to Forbes, 87% of companies consider Big Data will create major changes to
their industry until the end of the 2nd decade of the 21st century. Even the company also
think that without consideration on big data analytics and specific strategies based on
empirical analysis will effectively make them fall in its business.
There are many sources of Big data in most sectors and in different areas, not just in the
banking sector and financial services. Every interaction, every transaction of customers
at banks create electronic records, the backups are saved according to legal regulations,
and transactions in the office ATMs in different locations as well information stored in
the bank. Thanks to analyze Big Data, companies financial services no longer store the
data as required mandatory as in the past but now they are active, more active in the
extraction to get the results that are based on that offer solutions to improve operations,
increase the profitability of the organization.
In short, Big Data is an important resource, its nature core creates competitive advantage
in any one financial institution does especially when capturing the needs of consumers
increasingly complex though was more convenient, easier thanks to the boom of
10
technology and engineering. Big data will not only bring the new look, the creation of
the innovation process for each type of service to the customers but also ensure business
efficiency, risk and cost are minimized.
Identifying array of services, parts, functions within financial institutions, where Big
Data can be reviewed for the purpose exploited most efficiently based on a combination
of knowledge, business model and the ability to apply software technologies to create
competitive opportunities for the organization. Depending on the purpose, structure,
resources, capabilities vary from organization that will be more cases big data
applications ranging nature special, separately. Here are the use cases are the most
popular - are we research and selection - which banks and companies financial services
are performed to identify the value hidden deep inside the analysis of Big data.
Application of Big Data to investigate the customer’s spending habits
The bank has the ability to directly access information resources, abundant historical
data related to the habits and behaviors of customer spending. The bank also holds
information on the amount a customer is paid how much for example specific salary per
month, the amount to be transferred into a savings account, the money was paid to the
company provide utilities (e.g. electricity companies, companies providing internet
services, ..), while customers using banking services, etc. This provides a basis,
opportunities for banks access and deeper data analytics. Applying the information
screening function (filter function), for example as the filter time or holiday celebrations
and macroeconomic conditions (e.g. inflation, unemployment, .. ), the reasons for bank
employees can understand the cause of the impact as customer wage increases or
decreases and spending capacity of customers change how. This is one of the
fundamental elements for the process of risk assessment, screening, evaluation profile
lenders, evaluate the possibility of mortgage and offer financial products other (crossselling) to customers as insurance.
Banks benefit a lot if they know the information customers to withdraw cash - all the
money has been on payday - or if they want to keep the money on a credit card (credit
card) / debit (debit card). Take advantage of that, banks can reach customers, expand
service with the proposal, to attract customers to invest in short-term loans with high
payout ratio and the appropriate interest rate, etc.
Customer segmentation and review customer’s records
Once the initial analytics of the spending habits of customers with identifying the type
of service, channel transactions are priority customers (i.e. customers who want savings
or want to invest in loans), the will get a database serving the segment and classify
customers as appropriate based on the information and documents supplied by
clients. Customers who spend comfortable ease, investors cautious yet thorough,
11
customers pay the debts quickly, customers began to repay the maturing, Big Data will
give banks the knowledge, expertise and deep habits spending patterns of customers,
simplifying the task of identifying the needs and wants of them. By being able to track
each transaction by customers, the bank’s will be able to classify customers based on
various parameters, including services often customers use, time to use the service,
spending habits when using a credit card or even a net asset value (net worth - income
plus the value of customer assets minus liabilities).
Benefits that bring customer segmentation is that it allows banks to target customers with
better marketing campaigns relevant is designed to meet the exact needs of the customer.
Data analysis capabilities for Big Data rising companies and organizations BFSI grasp
the need to find hidden within each customer (customer insights) thereby creating
customer segments. However, the collection and evaluation of information the
requirements are investment in the infrastructure of the organization as well as
investment in affiliate network between all employees of departments, functional parts
of the organization technology, advanced engineering software for the process of
exploiting Big Data.
The sales include other services (service cross-selling)
Based on a database which banks can attract or retain customers by introducing more
other services. For example, banks can introduce investments with attractive interest
rates to customers who have idle money or investors’ always careful consideration in
making investment decisions. Or the bank has proposed short-term loans to customers
who have a habit of spending "comfortable" for the needs of their daily consumption or
customers who are having difficulty in paying old debts. Analyzing correctly on the
profile of the customer, the bank can cross-sell other services more efficient and attract
more customers with better deals to be "personalized" to focus precisely on demand
customer demand more efficiently, thereby increasing revenue for the company.
Building a system to record customer feedback
Customers can leave feedback after every transaction or every time to get advice from
the customer call center or via the feedback form, but often to share ideas through social
media, e.g. Facebook, Zalo ... Big Data tools can search for sifting through the
information and feedback publicly on the social media and collect all the data mentioned
on the brand of the bank to be able to respond quickly and fully to customers. Also
supports prevent rumors affecting business operations and customer confidence in banks,
this was already happened in some Vietnamese banks currently.
Once customers think that the bank is willing listen to them and appreciate their
comments as ideas related to service improvements, the bank can create more chances
to retain its customers. To do this better, the banks should build a data center - storage
12
centers all the interactions customers have with brands including private data base,
transaction history, browsing history, services, etc. with the purposes are to support
campaign developments to meet what the customers are expecting to increase their
loyalty.
Personalized marketing
As previously mentioned, the application of Big Data analytics into business strategy of
bank plays an important role to identify needs of each customer based on its comments,
feedback. In addition, consumption behavior is significantly explored through
transaction history. As a result, if the consumption information is clarified, it is quite
well to support the bank in direction of personalized marketing to individual customers.
Once customer segmentation is concerned by big data, banks can take advantages to
personalized marketing to target customers based on understanding of personal spending
habits of them. In addition, to obtain good database on the transaction history of
customers, the banking needs to combine data unstructured - a form of data Big Data obtained from social networking or social media such as customer profile on Facebook.
To get a more complete picture of the needs of customers based on the analysis of the
psychological desire at all times point. On the other hand, the data of the customer in the
background social media or social applications other smart will help banks analyze the
risks that may occur, but consider whether to provide loans or outside the evaluation of
dossiers as usual.
After analyzing and understanding the specific needs and particular of each customer,
the bank should continue to segment even further and provide solutions, marketing plans
accordingly to thereby obtain response rate recovery, higher conversion rate from each
customer. For example, banks use the e-mail marketing to be sent to customers the latest
information about the services for short-term loans with interest rates moderate, or
deposits with attractive interest rates, or chapters the other privileges, ... the creation of
products and services provided to each customer segment, or even each specific client
will help banks build brand image and build a good relationship in each client.
Flexible suggesting good services to customers
System Big Data can be a complex system linking various parts different functions, but
its job is to simplify the tasks of an organization officials. Whenever a customer name
or account number is entered into the system, the system of Big Data will support
screening all data and transmissions or provide the data required to serve the process
analysis. This will enable banks to optimize workflow and save both time and costs. Big
Data will also allow the organization to identify and fix problems before they affect their
customers.
