What’s New0 No open-source job application provides job semantic matching
0 All the job hunting web services just provide the searching result according to the latest creation time of the job position.
0 How to convert Json to RDF format0 We checked lots of converters however few of them provide this
feature, but most of them can only convert semantic file format.1.RDF Translator: http://ebusiness-unibw.org (NG)2.Karma:http://github.com/InformationIntegrationGroup/Web-Karma (Good)
