Figure 1 – Big data analysis in mobile Internet services

As a new technology, big data analysis in the mobile Internet services environment is different from general
big data analysis. Details are given below:
a) Complicated data flow: The big data analysis processes may include data collection, data
transaction, data analysis, data storage, and data application. A possible example of data flow is
shown in Figure 2.

Figure 2 – An example of data flow
b) Asynchronous structure: The diagram in Figure 2 shows that not only is the data flow rich and
complicated but the flow of data may also be asynchronous in nature and reaching near real time
may be challenging.

Generally, big data analysis in mobile Internet services constitutes of the following entities:
a) The data collection entity, which collects data from smart devices.
b) The data pre-processing entity, which aggregates data, unifies the data collected in different
formats, extracts data from unstructured data or semi-structured data into structured data.
c) The data analysis entity, which analyses the data of mobile Internet services in various data types
and formats.
d) The data application entity, which applies the big data results for services.
