Abstract
Due to the proliferation of information systems and technology, businesses increasingly have the capability to accumulate huge amounts of customer data in large databases.
However, much of the useful marketing insights into customer
characteristics and their purchase patterns are largely hidden and untapped.
Current emphasis on customer relationship management makes the marketing function an ideal application area to greatly benefit from the use of data mining tools for
decision support.
A systematic methodology that uses data mining and knowledge management techniques is proposed to manage the marketing knowledge and support marketing decisions. This methodology can be the basis for enhancing customer relationship management.
Introduction
In recent years, the advent of information technology
has transformed the way marketing is done and
how companies manage information about their customers.
The availability of large volume of data on
customers, made possible by new information technology
tools, has created opportunities as well as
challenges for businesses to leverage the data and
gain competitive advantage.
Wal-Mart, the largest retailer in the U.S.,
for example, has a customer database that
contains around 43 tera-bytes of data,
which is larger than the database used by the Internal
Revenue Services for collecting income taxes.
The Internet and the World Wide Web have made
the process of collecting data easier, adding to the
volume of data available to businesses. On the one
hand, many organizations have realized that the
knowledge in these huge databases are key to supporting
the various organizational decisions.
Particularly,the knowledge about customers from
These databases is critical for the marketing function.
But,much of this useful knowledge is hidden and untapped.
On the other hand, the intense competition and
increased choices available for customers have
created new pressures on marketing decision-makers
and there has emerged a need to manage customers
in a long-term relationship.
This new phenomenon, called customer relationship management,
requires that the organizations tailor their products and services
and interact with their customers based on
actual customer preferences, rather than some assumed
general characteristics.
As organizations move towards customer relationship management,
the marketing function, as the front-line to interact with customers,
is the most impacted due to these changes.
There is an increasing realization that
effective customer relationship management can be
done only based on a true understanding of the needs
and preferences of the customers. Under these conditions,
data mining tools can help uncover the hidden
knowledge and understand customer better, while a
systematic knowledge management effort can channel
the knowledge into effective marketing strategies.
This makes the study of the knowledge extraction
and management particularly valuable for marketing.
Developments in database processing,
data warehousing, machine learning
and knowledge management have contributed
greatly to our understanding of the data mining process.
More recent research on data mining
and knowledge discovery has further enhanced
our understanding of the application of data
mining and the knowledge discovery process. But,
most research has focused on the theoretical and
computational process of pattern discovery and a
narrow set of applications such as fraud detection or
risk prediction. Given the important role played by
marketing decisions in the current customer-centric
environment, there is a need for a simple and integrated
framework for a systematic management of
customer knowledge. But, there is a surprising lack
of a simple and overall framework to link the extraction
of customer knowledge with the management
and application of the knowledge, particularly in the
context of marketing decisions. While data mining
studies have focused on the techniques, customer
relationship studies have focused on the interface to
the customer and the strategies to manage customer
interactions. True customer relationship management
is possible only by integrating the knowledge discovery
process with the management and use of the
knowledge for marketing strategies. This will help
marketers address customer needs based on what the
marketers know about their customers, rather than a
mass generalization of the characteristics of customers
We address this issue in this paper by presenting
an integrated framework for knowledge discovery
and management, in the context of marketing decisions.
Marketing decisions based on discovered
customer knowledge leads to knowledge-based Marketing.
