1---------Java call Nlpir (ICTCLAS2016) for word breaker

Remark: Win7 64-bit system, NetBeans programming

Nlpir participle System, formerly known as the 2000 ictclas,2009 year. Created by Dr. Zhang Huaping.

implementation Steps :

1, in NetBeans, file → new project →java→java application; project name: CWORDSEG;
2. Copy the code from the Nlpirtest.java \sample\jnatest_nlpir\src\code in the Nlpir file into the Cwordseg.java;

The initial modification code is shown:

(1) Revise the package declaration to cwordseg;
(2) refactoring the class name nlpirtest to Cwordseg;
Methods: Right-click cwordseg.java→ reconstruction → Rename, renamed to cwordseg→ Reconstruction;

If you simply modify the class name in the code, you still need to refactor, or the runtime will error: The main class cwordseg cannot be found.
(3) Import Utils. Systemparas; Not used, temporarily commented out.

3. Copy the Utils folder under the Nlpir file ... \sample\jnatest_nlpir\src directly to the SRC folder of the project cwordseg;

4, the Nlpir file under the \sample\jnatest_nlpir\lib under the Jna-4.0.0.jar import into the project library;
Method (1): Right-click library → add jar→ select Jna-4.0.0.jar Import;
Method (2): Copy the Jna-4.0.0.jar file directly into the project ... \cwordseg\lib folder.
After the guide, the project catalogue is as follows:

5. Create a new folder in the Project Cwordseg folder file:
(1) Copy all the data folders in the Nlpir to the file folder;
(2) The \lib\Win64 folder is also copied to the file folder ( Note : If it is Win32 or Linux, select the corresponding folder).

6. Modify part of Code 2:
(1) Modify the path where the file NLPIR.dll is located, and it is copied into the Win64 folder in the 5th step, for example:
D:\\netbeansprojects\\cwordseg\\file\win64\\nlpir
Note : The last Nlpir is the file name, do not add the suffix . dll.
Attached: has been tested, if the 64-bit operating system, the use of 32-bit files will be error.

(2) The path where the data folder is repaired (that is, the Data folder in step 5th), as shown in:
D:\\netbeansprojects\\cwordseg\\file

(3) Other places that can be changed:
Encoding format: int charset_type = 1; Change to a different value.
Among them: GBK corresponding to 0,utf-8 corresponding 1,big5 corresponding to 2, containing traditional Chinese GBK corresponding to 3.

The following code is simplified :

Systemparas; 5 Importcom.sun.jna.Library; 6 Importcom.sun.jna.Native; 7   8 /** 9  *  Ten * Function: Basic word-breaker function One * Last updated: March 14, 2016 21:01:21 A  */   -    -  Public classcwordseg { the     //define interface Clibrary, inherit from Com.sun.jna.Library -      Public InterfaceClibraryextendsLibrary { -         //defines and initializes a static variable for the interface, which is used to load NLPIR.dll, the path points to the file NLPIR.dll, but without the suffix DLL -Clibrary Instance = (clibrary) native.loadlibrary ("D:\\netbeansprojects\\cwordseg\\file\\win64\\nlpir", CLibrary.class);  +         //initialization function declaration: Sdatapath is the initialization path address, including the core thesaurus and the path to the configuration file, encoding the encoded format of the input character -          Public intNlpir_init (String Sdatapath,intencoding,string Slicencecode);  +         //word breaker function declaration: SSRC is a string to be divided, bpostagged=0 means not to do part-of-speech labeling, bpostagged=1 means to do pos tagging A          PublicString Nlpir_paragraphprocess (String sSrc,intbpostagged);  at         //gets the function declaration of the last error message -          PublicString nlpir_getlasterrormsg ();  -         //Exit Function Declaration -          Public voidNlpir_exit ();  -     }   -        in      Public Staticstring transstring (String aidstring,string ori_encoding,string new_encoding) { -         Try {   to             return NewString (Aidstring.getbytes (ori_encoding), new_encoding);  +}Catch(unsupportedencodingexception e) { - E.printstacktrace ();  the         }   *         return NULL;  $     }  Panax Notoginseng        -      Public Static voidMain (string[] args)throwsException { theString Argu = "D:\\netbeansprojects\\cwordseg\\file";//This path points to the Data folder (System kernel thesaurus) +         //String system_charset = "UTF-8";  A         intCharset_type = 1;//UTF-8 encoding mode, the other GBK corresponding to 0,big5 corresponding to 2, including the traditional Chinese GBK corresponding 3 the         intInit_flag = CLibrary.Instance.NLPIR_Init (Argu, Charset_type, "0");//Run initialization function, Success returns 1, failure returns 0 + String nativebytes;  -    $         //initialization failure Prompt $         if(0 = =Init_flag) {   -Nativebytes = CLIBRARY.INSTANCE.NLPIR_GETLASTERRORMSG ();//Get error message -SYSTEM.ERR.PRINTLN ("Initialization failed! Reason: "+nativebytes);  the             return;  -         }  Wuyi            theString SInput = "This is a book about information retrieval. ";//Manual input of string sinput -         Try {   WuNativebytes = CLibrary.Instance.NLPIR_ParagraphProcess (sInput, 1);//Run the word breaker function -SYSTEM.OUT.PRINTLN ("Participle result is:" + nativebytes);//Output Word Segmentation results AboutCLibrary.Instance.NLPIR_Exit ();//Exit $}Catch(Exception ex) { -             //TODO auto-generated Catch block - Ex.printstacktrace ();  -         }   A     }   +}

Operation result :

Error resolved : Main class cwordseg not found

The class name is modified in the 2nd step and needs to be modified in the correct way, or by refactoring.
