X2R是一個能夠幫助使用者將舊有資料輕鬆的轉換至RDF格式的工具,以現有的技術要將舊有資料轉換至RDF是十分耗費使用者對於鏈結資料相關技術知識並且相當耗時。現有轉換技術大多為在轉換前先處理舊有資料,使其能符合轉換工具之要求,若對於此轉換流程不熟悉的初學者直接將尚未經過處理的舊有資料進行轉換,則有可能會產生bad node (壞點),而X2R的訴求就是要幫助使用者處理這些包含bad nodes的檔案。X2R能夠幫助使用者至網路上搜尋能夠取代這些bad nodes的URI(統一資源標誌符)並且將其替換,以產出能夠被重複利用、完整的RDF檔案。如此一來轉換的門檻降低,相信鏈結資料也能更加的普及。
X2R is a tool for translating data in legacy formats to linked data in RDF format. By observing, the conversion processes are challenging and time consuming for many developers in general. Pre-processing of the input data is typically necessary in order to capture the semantics of the input data and make the data conform to the conventions of the selected translator. If a novice developer decided to skip this step and to use the default settings. As a result, this RDF file produced automatically often contain temporary URIs generated by the translator. The file may also have blank nodes. Clearly, one cannot search for these types of nodes. Their presence in a file hinders the discovery of the content of the file. For this reason, we refer to them as bad nodes. To improve the quality of the RDF file produced by post-processing. We present X2R to help the developer who is not familiar with RDF format and related techniques. X2R performs the replacement of bad nodes minted by translators with reusable URIs found in popular endpoints and internal ontology by supporting URI searching and URI replacing functionalities.
