Chista is a search engine based on linked data. This project is implemented and executed in Ferdowsi University of Mashhad’ WTLab. The engine’s task is to collect semantic data from the web (especially Cloud of linked open data), to index them in an RDF repository and lastly to give access to the variety of tools for searching for data. Chsita can be used by both human users (with web-based user interface) and software (web-based services). The Chista project is sponsored by Iran’s IT organization and counted as an infrastructure for researchers in semantic web fields.
