WebService::GoogleHack::Rate
To use this module you would also need some extra files. They are: adjectives_list.txt nouns_list.txt adverbs_list.txt verbs_list.txt.
You would also need the WebService::GoogleHack::Text package to use this module.
use WebService::GoogleHack::Rate; my $search = WebService::GoogleHack::Rate->new(); #create an object of type Rate $results=$search->measureSemanticRelatedness("string 1", "string 2");
The PMI measure is stored in the variable $results, and it can also be accessed as $search->{'PMI'};
$results=$search->predictSemanticOrientation("file", "positive", "negative","trace file");
The resutls can be accessed through $results->{'prediction'} & $results->{'PMI Measure'}
or $search->{'prediction'} & $search->{'PMI Measure'}
WebService::GoogleHack::Rate - This package uses Google to do some basic natural language processing. For example, given two words, say "knife" and "cut", the module has the ability to retrieve a semantic relatedness measure, commonly known as the PMI (Pointwise mututal information) measure. The larger the measure the more related the words are. The package can also predict the semantic orientation of a given paragraph of english text. A positive measure means that the paragraph has a positive meaning, and negative measure means the opposite.
