unstructured data lacks a predefined manner of arrangement. An example of unstructured data is
data collected from social media responses. Inducing structure into text-based data is the process
of classifying text data into fields with records or files which makes it easier to analyze. There
are several ways that text-data can be converted into structured data (Tu et al., 2016).
In order to structure text-data, an individual or organization can begin with the creation of
data dictionary which identifies some commonly repeated texts with important implications in
data analysis. These key words are words that the system finds to recur. After creating the
