In this paper, we investigate two research questions: RQ1) How is uncertainty related to revert, RQ2) What kinds of category is uncertainty divided into? The result of the study is as follows. For RQ1, since the cause of the bug is uncertain in revert commits, there are many cases where revert is performed as a response. In addition, in the case of reverted commits, there are many cases where a commit that has been provisionally processed is later reverted. On the other hand, for RQ2, uncertainty in OSS projects can be divided into the following five categories: uncertainty in the content of an exception, uncertainty associated with bugs, uncertainty about future changes, uncertainty related to changes, and uncertainty about the code. In addition, we have found that uncertainty related to bugs tends to appear frequently. Uncertainty to be fixed with high priority is uncertainty in which the cause of the bug is unclear or uncertainty dealt with exceptionally.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"929","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"918","bibliographicIssueDates":{"bibliographicIssueDate":"2020-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"61"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00204243","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"}}
