How to resolve disambiguation in Yago/DBpedia?

Assuming I am searching for an entity such as "Wizard of Oz" and know I am specifically interested in the book rather then movie or musical. Which query/method will return correct results on most cases?

As every book, and only books, have an ISBN, I guess you can take Steve Harris' query and, instead of asking if it is a book, you can ask if it has an ISBN.

SELECT * WHERE {
  ?s <http://dbpedia.org/property/name> ?name .
  ?s <http://dbpedia.org/ontology/isbn> ?isbn .
  FILTER(regex(STR(?name), "wizard of oz", "i"))
}

You can also do that with DBpedia Lookup:

http://lookup.dbpedia.org/api/search.asmx/KeywordSearch?QueryClass=book&QueryString=wizard+of+oz

Or with DBpedia Spotlight:

http://spotlight.dbpedia.org/rest/candidates?text=wizard+of+oz+book

You can do that with a query like:

SELECT * WHERE {
  ?s <http://dbpedia.org/property/name> ?name .
  ?s a <http://dbpedia.org/ontology/Book> .
  FILTER(regex(STR(?name), "wizard of oz", "i"))
}
