Researcher’s paradigm is tricky concept. The problem starts with the term itself, with authors using various terms to refer to the same concept. The used terms include Researcher’s philosophy, philosophical worldview and Researcher’s framework.
Regardless, the paradigm is essentially an umbrella term that refers to the researcher’s ontology and epistemology.
According to Oxford Advanced Learner's Dictionary, Ontology refers to the branch of philosophy that deals with the nature of existence. Epistemology on the other hand refers to the part of philosophy that deals with knowledge. Epistemology is a theory of knowledge, especially with regard to its methods, validity, and scope, and the distinction between justified belief and opinion.

A great resource I found online is an article by Professor Ørjan Totland, I found on the Norwegian University of Science and Technology website. Here http://www.idi.ntnu.no/grupper/su/publ/html/totland/ch032.htm
