i would know if i can install dbpedia spotlight on os windows 7 (x64) and set up the DBpedia Spotlight environment on Eclipse.
if i can pleas give me any tutorial , can't find any one talking about dbpedia spotlight and win7.
DBpedia Spotlight runs on the Java Virtual Machine, so it should run on Win7 if it has some implementation of the JVM installed. http://www.java.com/en/download/testjava.jsp
If you do have Java, you can just run the service from the jar.
See the quickstart instructions: https://github.com/dbpedia-spotlight/dbpedia-spotlight#run-your-own-server
