概要	The online research diary method is a data collection technique in which participants document their experiences, thoughts, or behaviours in structured or open-ended digital diary entries over a defined period. Delivered via email, web forms, blogging platforms, or dedicated apps, it captures temporally proximate, naturalistic data that retrospective interviews cannot provide. It is widely used in health research, education, psychology, and social sciences.	An online semi-structured interview is a qualitative data collection technique in which a researcher conducts a guided but flexible conversation with a participant over a digital medium — video call, telephone, chat, or email — using a prepared interview guide with open-ended questions while remaining free to probe, reorder, or add follow-up questions as the dialogue unfolds. It combines the accessibility of remote communication with the depth and adaptability of semi-structured inquiry.
