问题
Does DBpedia name have any standard or convention? By that, I mean, e.g., United Kingdom has a resource named United_Kingdom. But I'm seeing that the fact of having an underscore and having each word being capitalized doesn't hold. For instance, take University_of_Manchester; if you type it as University_Of_Manchester with a capital ‘O’ in “of,” you won't get the resource. Is it obligatory to do a filtering to get the resource name in the proper case, because we may want to make all letters lowercase, have underscore in spaces and just make a query because doing in filtering in the SPARQL do takes some time.
Any suggestions? I've just started to learn about DBpedia, so I may be missing something.

DBpedia encodes the information available in Wikipedia, and its naming convention is based on the names of Wikipedia articles. The DBpedia wiki page, The DBpedia Data Set, says, in Section 3. Denoting or Naming “Things”:
Each thing in the DBpedia data set is denoted by a de-referenceable IRI- or URI-based reference of the form http://dbpedia.org/resource/Name, where Name is derived from the URL of the source Wikipedia article, which has the form http://en.wikipedia.org/wiki/Name. Thus, each DBpedia entity is tied directly to a Wikipedia article. Every DBpedia entity name resolves to a description-oriented Web document (or Web resource).
Until DBpedia release 3.6, we only used article names from the English Wikipedia, but since DBpedia release 3.7, we also provide Internationalized Datasets that contain IRIs like http://xx.dbpedia.org/resource/Name, where xx is a Wikipedia language code and Name is taken from the source URL, http://xx.wikipedia.org/wiki/Name.
Thus, since the Wikipedia article is University of Manchester, not University Of Manchester, the DBpedia resource is http://dbpedia.org/page/University_of_Manchester, and not http://dbpedia.org/page/University_Of_Manchester.
