To assure traceability and reproducibility of the data/results is the most important role of Open Science in addition to sharing the results of researches among wide societies. However, a time a researcher can spend to read one research paper seems to keep decreasing in these days as a result of the continuous increase in the number of published papers per year. Consequently, number of papers that pick up and cite the results and conclusions of other papers without checking their reproducibility/traceability also seems to increase recently. This trend seems to be enhanced by journals publishing short papers that present only the digest of results and conclusions with highly interpretative figures in the main text, and raw data, evaluation of their reliability, explanation on their processing to secondary data are not given in the main text but put in supplements and/or data repository. This style makes it difficult and time-consuming to trace back to the raw data. Consequently, most of readers except those who really are interested in the results and conclusions, do not trace back to the raw data and evaluate their reproducibility and traceability. Moreover, evaluation of reliability, reproducibility, and traceability of the data stored in supplements and/or repository by reviewers and editors seems less sufficient in many cases. As a result, there seem to exist many cases that is not clear how the authors convert the raw data to the processed (secondary) data, or error or reproducibility is not properly evaluated for the processed data.
On the other hand, there exist honest researchers who care about reproducibility and traceability of their data, and desire to properly present and explain assumptions to process their raw data, limitations to apply their processed and interpretative data, and so on. PEPS cares about reproducibility of the result, and spends great deal of efforts to make the raw data easy to be traced and make the result easy to reproduce within the main text. In the presentation, I would like to introduce PEPS’s efforts and facing problems on this subject, and hope to have constructive opinions and advices from the audience.
