Collection of examples is an important part that determines the basis of language research on actually used language data. The conventional collection method of usage examples can be primarily divided into two cases: (i) A case where a researcher personally collects examples from media, such as newspapers or novels, and (ii) a case where a researcher uses a public corpus constructed based on these media. However, the distinction between such cases became diluted with the emergence of new media. This is because of the shift that occurred from a print-based to a digital-based era, allowing anyone, including individual researchers, to collect examples and build a corpus easily. The software and online homepage introduced in this study are typical examples of easy establishment of a “multimedia corpus equipped with ‘keyword in context’ (KWIC) video automatic generation technique” based on user videos. Further studies need to be conducted to examine the characteristics of language research in an era where the boundary between collection of examples and the corpus construction is blurred.
