Text Analysis

 

TEXT AND DATA MINING (TDM) is the computational analysis of vast quantities of digital information, whether free-form natural language text or structured data. Using specialized software, researchers can extract data, identify trends, look for patterns and better understand the relationships of terms within and between documents. Analysis might focus on word frequency, words that frequently appear near each other, contextual information for key words, common phrases and other patterns. Materials to be analyzed range from websites (such as publicly available Facebook posts), 16th C. manuscripts, DNA sequences, to old newspapers.
