Blacklist From an exhaustive set of Wikipedia topic titles was derived a blacklist consisting of entries that had to satisfy four criteria: 1) no more than three words in length; 2) has no closed-class words, such as prepositions or adverbs; 3) must begin with an adjective and end with a noun (determined by WordNet); and 4) does not contain any numerical characters or miscellaneous symbols that are usually not meaningful in English.
each title in the resultant list is literally a short noun phrase with adjectives as premodifiers.
