Final answer:
The correct option is B) Text mining. Text mining tools are utilized to analyze large unstructured data sets and discover patterns and relationships by identifying connections between ideas.
Step-by-step explanation:
The tools used to analyze large unstructured data sets like e-mail, memos, survey responses, etc., to discover patterns and relationships are known as Text mining tools. They are used to identify relationships between ideas, patterns of organization, and interplay between verbal and nonverbal elements in a diverse range of texts. By employing sophisticated algorithms, text mining applications can parse through huge amounts of textual content to extract meaningful quantitative data and support the identification of previously unknown patterns or relationships within the data. This process often utilizes methodologies such as eigen-based principal components analysis, multidimensional scaling, cluster analysis, and other forms of data ordination to provide a comprehensive analysis of text-based data.
The correct answer is Text mining (option B). Text mining tools are used to analyze large unstructured data sets, such as e-mail, memos, survey responses, etc., to discover patterns and relationships in the text. These tools employ techniques like natural language processing, machine learning, and statistical analysis to extract meaningful information from the text.
