I'm doing a project and asp.net is one of my possible choices (the other one being php). I need to implement some semantic functionality to improve searches. I know some php frameworks support semantics but i want to know if asp.net has any[The most used] tool (3rd party or built in) that will also support this.
I've been reading more about this subject and i think what i'm really looking for is tools in order to deliver more accurate results to user searches by not only matching word but its meanings.
I'm sorry if the semantic web term caused confusion but my guide teacher called it like that
You should look into dotNetRDF and ARC PHP.
Other good resources
That last one is about the recommended way to markup HTML with semantic meaning. Improving your search results to include meaning can be done a number of ways and may or may not include using the semantic web technology stack per se. Perhaps you only mean adding tags to blogs, or faceted searching such as that provided by SOLR. You may need to clarify what kind of searching you want to do.
