In a ‘mixed methods’ research approach, researchers collect and analyze both quantitative and qualitative data as part of the same study.
Text mining, or text data mining, is the process of deriving high-quality information from text. This information is typically obtained by devising patterns and trends by means such as statistical pattern learning. Text mining usually involves the process of structuring the input text, deriving patterns, and then evaluating and interpreting the output. 'High quality' in text mining usually refers to some combination of relevance, novelty, and interest. Typical text mining tasks include text categorization, text clustering, concept/entity extraction, production of granular taxonomies, sentiment analysis, document summarization, and entity relation modeling.

A systematic review attempts to collate all empirical evidence that fits pre-specified eligibility criteria in order to answer a specific research question.
"Reliability refers to how dependably or consistently a test measures a characteristic. If a person takes the test again, will he or she get a similar test score, or a much different score? A test that yields similar scores for a person who repeats the test is said to measure a characteristic reliably. "
"Validity refers to what characteristic the test measures and how well the test measures that characteristic."
"It is important to understand the differences between reliability and validity. Validity will tell you how good a test is for a particular situation; reliability will tell you how trustworthy a score on that test will be. You cannot draw valid conclusions from a test score unless you are sure that the test is reliable. Even when a test is reliable, it may not be valid. You should be careful that any test you select is both reliable and valid for your situation."

First: Ask yourself whether you absolutely need the data for your purpose, and only collect the data you need.
