Big Data Applications
Abstract
In the previous chapter, we examined big data analysis, which is the
final and most important phase of the value chain of big data. Big data analysis
can provide useful values via judgments, recommendations, supports, or decisions.
However, data analysis involves a wide range of applications, which frequently
change and are extremely complex. In this chapter, the evolution of data sources
is reviewed. Then, six of the most important data analysis fields are examined,
including structured data analysis, text analysis, website analysis, multimedia
analysis, network analysis, and mobile analysis. This chapter is concluded with a
discussion of several key application fields of big data.
6.1
Application Evolution
Recently, big data and big data analysis has been proposed for describing datasets
and as analytical technologies in large-scale complex programs, which need to
be analyzed with advanced analytical methods. As a matter of fact, data driven
applications have emerged in the past decades. For example, as early as 1990s,
business intelligence has became a prevailing technology for business applications
and, network search engines based on massive data mining processing emerged
in the early twenty-first century. Some potential and influential applications from
different fields and their data and analysis characteristics are discussed as follows.
Evolution of Commercial Applications
: The earliest business data was generally
structured data, which was collected by companies from old systems and then
stored in RDBMSs. Analytical technologies used in such systems were prevailing
in 1990s and was intuitive and simple, e.g., reports, instrument panels, special
queries, search-based business intelligence, online transaction processing, inter-
active visualization, score cards, predictive modeling, and data mining [

the beginning of twenty-first century, networks and websites has been providing a
unique opportunity for organizations to have online display and directly interact
