Hi, All.
I've implemented some sample code using NSLinguisticTagger class and i've found
some weird behavior.
I'me using the following code to analyze a simple english phrase:
NSRange textrange = NSMakeRange(0, [phrase length]);
[tagger enumerateTagsInRange:textrange
scheme:NSLinguisticTagSchemeLexicalClass
options:0
usingBlock:
^(NSString *wordType,
NSRange wordRange,
NSRange sentenceRange, BOOL *stop)
{
if(wordType == NSLinguisticTagNoun)
{
// Show tag
}
if(wordType == NSLinguisticTagPronoun)
{
// Show tag
}
if(wordType ==
NSLinguisticTagDeterminer)
{
// Show tag
}
…etc for each NSLinguisticSomething
constant.
}];
If I analyze the phrase: "I am a woman" I got the correct result :
I --> pronoun
am --> verb
A --> determiner
woman --> noun
but if i analyze the phrase: "I am a man" I got the result:
I --> otherword
am --> otherword
a --> otherword
man --> otherword.
I've initialized the NSLinguisticTagger class as follow:
NSArray *tagScheme = [NSArray
arrayWithObjects:NSLinguisticTagSchemeLexicalClass,
NSLinguisticTagSchemeNameType,
NSLinguisticTagSchemeLanguage, nil];
tagger = [[NSLinguisticTagger alloc] initWithTagSchemes:tagScheme
options:0];
So where is my mistake? Why I get an error if I try to analyze a simple phrase
like "I am a man"?
The behavior is the same on the device (iOS 5.0.1) and on the simulator. I'm
using MaOS X 10.7.2 with Xcode 4.2.
Thanks for any answer.
Luca.
