Google Refine is a power tool for cleaning up raw data, making it consistent, linking it to data registries like Freebase, augmenting it with more data from other data sources, transforming it into the required format for other tools to consume, and contributing it back to some data sources like Freebase. Google Refine is not a web service but a desktop app that runs on your own computer, so you can process sensitive data with privacy.
The LDSpider project aims to build a web crawling framework for the linked data web. Requirements and challenges for crawling the linked data web are different from regular web crawling, thus this projects offer a web crawler adapted to traverse and harvest sources and instances from the linked data web. We offer a single jar which can be easily integrated into own applications.
