To run the example project, run pod try objc-ngram.
The demo loads sentences.txt and lets you search for free-formed text in it.
objc-ngram is available through CocoaPods, to install it add the following line to your Podfile:
pod "objc-ngram"
Import OCNDictionary.
#import <objc-ngram/OCNDictionary.h>Create an OCNDictionary and add objects to it with a given key. The key must be a string and is split into 3-grams.
OCNDictionary *dict = [OCNDictionary dictionary];
[dict addObject:@"red brown fox" forKey:@"red brown fox"];
[dict addObject:@"white big bear" forKey:@"white big bear"];
[dict addObject:@"hiding rabbit" forKey:@"hiding"];
NSArray *results = [dict matchObjectsForKey:@"white fox"];
for (OCNObjectScore *result in results) {
NSLog(@"'%@' has a score of %f", result.object, result.score);
}This will output the following.
'white big bear' has a score of 1.416667
'red brown fox' has a score of 0.181818
You can create a OCNDictionary with a different n-gram size.
OCNDictionary *dict = [OCNDictionary dictionaryWithNgramWidth:4];See CONTRIBUTING.
