Public Member Functions | |
| PorterStemmer () | |
| virtual void | Reset () |
| reset() resets the stemmer so it can stem another word. If you invoke the stemmer by calling add(char) and then stem(), you must call reset() before starting another word. | |
| virtual void | Add (char ch) |
| Add a character to the word being stemmed. When you are finished adding characters, you can call stem(void) to process the word. | |
| override System.String | ToString () |
| After a word has been stemmed, it can be retrieved by toString(), or a reference to the internal buffer can be retrieved by getResultBuffer and getResultLength (which is generally more efficient.) | |
| virtual System.String | Stem (System.String s) |
| Stem a word provided as a String. Returns the result as a String. | |
| virtual bool | Stem (char[] word) |
| Stem a word contained in a char[]. Returns true if the stemming process resulted in a word different from the input. You can retrieve the result with getResultLength()/getResultBuffer() or toString(). | |
| virtual bool | Stem (char[] wordBuffer, int offset, int wordLen) |
| Stem a word contained in a portion of a char[] array. Returns true if the stemming process resulted in a word different from the input. You can retrieve the result with getResultLength()/getResultBuffer() or toString(). | |
| virtual bool | Stem (char[] word, int wordLen) |
| Stem a word contained in a leading portion of a char[] array. Returns true if the stemming process resulted in a word different from the input. You can retrieve the result with getResultLength()/getResultBuffer() or toString(). | |
| virtual bool | Stem () |
| Stem the word placed into the Stemmer buffer through calls to add(). Returns true if the stemming process resulted in a word different from the input. You can retrieve the result with getResultLength()/getResultBuffer() or toString(). | |
| virtual bool | Stem (int i0) |
Static Public Member Functions | |
| static void | Main (System.String[] args) |
| Test program for demonstrating the Stemmer. It reads a file and stems each word, writing the result to standard out. Usage: Stemmer file-name | |
Properties | |
| virtual int | ResultLength [get] |
| Returns the length of the word resulting from the stemming process. | |
| virtual char[] | ResultBuffer [get] |
| Returns a reference to a character buffer containing the results of the stemming process. You also need to consult getResultLength() to determine the length of the result. | |
Stemmer, implementing the Porter Stemming Algorithm
The Stemmer class transforms a word into its root form. The input word can be provided a character at time (by calling add()), or at once by calling one of the various stem(something) methods.
