Method Summary

Methods

Modifier and Type	Method and Description
AnalyzedTokenReadings	createNullToken(String token, int startPos) Create the AnalyzedToken used for whitespace and other non-words.
AnalyzedToken	createToken(String token, String posTag) Create a token specific to the language of the implementing class.
List<AnalyzedTokenReadings>	tag(List<String> sentenceTokens) Returns a list of AnalyzedTokens that assigns each term in the sentence some kind of part-of-speech information (not necessarily just one tag).

Method Detail

tag

List<AnalyzedTokenReadings> tag(List<String> sentenceTokens)
                                throws IOException

Returns a list of AnalyzedTokens that assigns each term in the sentence some kind of part-of-speech information (not necessarily just one tag).

Note that this method takes exactly one sentence. Its implementation may implement special cases for the first word of a sentence, which is usually written with an uppercase letter.

Parameters:

sentenceTokens - the text as returned by a WordTokenizer

Throws:

IOException

createNullToken

AnalyzedTokenReadings createNullToken(String token,
                                    int startPos)

Create the AnalyzedToken used for whitespace and other non-words. Use null as the POS tag for this token.

createToken

AnalyzedToken createToken(String token,
                        String posTag)

Create a token specific to the language of the implementing class.
