Convert a collection of raw documents to a matrix of TF-IDF features. TfidfTransformer applies Term Frequency Inverse Document Frequency normalization to a sparse matrix of occurrence counts. However, CountVectorizer tokenize the documents and count the occurrences of token and return them as a sparse matrix.

# Sample data for analysis
data1 = "Java is a language for programming that develops a software for several platforms. A compiled code or bytecode on Java application can run on most of the operating systems including Linux, Mac operating system, and Linux. Most of the syntax of Java is derived from the C++ and C languages."
data2 = "Python supports multiple programming paradigms and comes up with a large standard library, paradigms included are object-oriented, imperative, functional and procedural."
data3 = "Go is typed statically compiled language. It was created by Robert Griesemer, Ken Thompson, and Rob Pike in 2009. This language offers garbage collection, concurrency of CSP-style, memory safety, and structural typing."

df1 = pd.DataFrame({'Java': [data1], 'Python': [data2], 'Go': [data2]})
