Keywords:Database, Minna de Honkoku, Open collaboration, Crowdsource
“Minna de Honkoku” (https://honkoku.org/) is crowdsourced and online collaborative project to transcribe historical materials written in old Japanese and is a good example of open collaboration or open science. "Minna de Honkoku" was launched as an online citizen science project to transcribe earthquake-related historical materials from Earthquake Research Institute Library, the University of Tokyo. On July 2019, we have upgraded the system of Minna de Honkoku to support IIIF, International Image Interoperability Framework. We can now transcribe broader range of manuscripts on digital archives adopting IIIF. We have extended the subjects of the project, which now covers wide variety of historical materials as well as earthquake-related materials. We have also implemented AI-assisted transcription. Two AI engine suggest transcription of character, when users asked to help. "Minna de Honkoku" consists of viewer of document image and vertical (Japanese-style) editor for transcription. Users can input transcribed texts viewing its image. The ranking of characters transcribed is displayed to keep motivation of users. Until February 2022, over 6,500 people registered for the project. We have loaded 1851 documents on the project. Total number of characters transcribed is about 10 million.
