Use Stanford NLP with Android

Posted on May 14, 2016 | Leave a comment

Steps:
1. Download the whole nlp from the site.
2. Copy stanford-postagger.jar file and paste it in the app>libs folder
3. Right click on it and click add to library.
4. Now write the example code available in the net with class tagText{} and in MainActivity.java
5. import library import import edu.stanford.nlp.tagger.maxent.MaxentTagger;

This video may help.

Update: It is giving errors with android.

					x++;
					triangularNumber=triangularNumber+x;
				}
				
				if(triangularNumber==number){
					return true;
				}else
				{
					return false;
				}
				
			}
		}
		Number myNumber = new Number();
		myNumber.number=7;
		System.out.println(myNumber.isTriangular());
	}

}

public class NumShape {

public static void main(String[] args) {

class Number{

int number;

public boolean isTriangular(){

int x=1;

int triangularNumber=1;

while(triangularNumber<number)

int main()

{

int counts=0;

for(int i=1000; i>=1; i--)

{

counts++;

printf("%d\t",i);

if(counts%5==0)

{

printf("\n");

}

return 0;

}

2nd approach:

#include<iostream>
#include<cstdio>
using namespace std;
int main()
{

    for(int i=1000; i>=1; i--)
    {
        if((i!=1000)&&(i%5==0))
        {
             printf("\n");
        }
         printf("%d\t",i);
    }

    return 0;
}
