structure.Then to the SMS goal,the principle of design,the system construction and the system
major function module will carry on the explanation,has given the future SMS system exhaustive
demand analysis.In view of the existing SMS insufficiency,in line with revolves “as center
provides the policy-making support take the customer” the thought that proposed will increase
the consumer behavior analysis,the customer community in the existing SMS foundation to
devide functions and analysis and customer value localization analysis provides the
policy-making support to future digital television service development.Then in view of the local
actual situation as well as the existing sample database peaceful lag’s database
characteristic,proposed when carries on the customer consumer behavior analysis uses only needs
the FP-growth algorithm which carries on two times traversal to implement the connection rule
excavation,which decrease the number of visiting database greatly,with the aim of discovering the
customer fast to program meal fondness,provides the policy-making support for the program
meals’s order and the preferential benefit strategy’s formulation.After analyzing the customer
community and comparing with each kind of cluster analysis method characteristic, According to
the sample database characteristic, synthesized based on the density and proposed based on the
grid method thought one kind of new CLIQUE the algorithm, this algorithm synthesized the
above two method merit to be able good to discover the digital television customer community
the characteristic, what thus was better was aims at the different client base formulation
marketing strategy to provide the policy-making support. When carries on the customer value
localization analysis, has analyzed the decision tree method characteristic, according to the
sample database characteristic, has chosen compares in the speed and the accurate aspect has the
superiority ID3 algorithm. Because ID3 has the strict limit in the usable aspect, difficulty with
truly applies, therefore proposed in the ID3 algorithm's foundation one kind of improvement's
ID3 algorithm and confirmed its accuracy to adapt the sample database request, has provided the
policy-making support for the customer retention and the development. Finally, has carried on the
summary to the full text, pointed out that is unable under the existing condition with the CAS
engagement question as well as take each program as in unit's frequency bundle to implement,
also has indicated the direction for the later work.
