Output Term Frequency-inverse Document (TFIDF) Matrix
Apr 7, 2014
I have this code that outputs the tfidf for all words in each file in the directory. I'm trying to transfer this to a matrix where each row correspond to each file in the directory and each column to all words in the files and I have some difficulty in doing it . Here is my try
public class TestTF_IDF {
public static void main(String[] args) throws UnsupportedEncodingException, FileNotFoundException{
//Test code for TfIdf
TfIdf tf = new TfIdf("E:/Thesis/ThesisWork/data1");
//Contains file name being processed
String file;
tf.buildAllDocuments();
I am doing final year project on keyphrase extraction from document. I complete extraction which has only nouns. Now I want to calculate TFIDF for those nouns. I don't know how to do that. I prefer java.
public static void main(String[]args) { Scanner input = new Scanner(System.in); System.out.print("Type your text: "); String text = input.nextLine(); int counter = text.length(); if(text.length()> 16)
[Code] ....
And input is: abcdefghijklm
output is:
Java Code:
a b c d e f g h i j k l m x x x mh_sh_highlight_all('java');
So all i want is, if i type: abcdefghijklm
I want this output:
Java Code:
a e i m b f j x c g k x d h l x mh_sh_highlight_all('java');
I have to find where in the fibonacci sequence a at number belongs, using a while loop.
Example
>55 is a Fibonacci number whose order in the sequence is 11 >35 is not a Fibonacci number. However, it lies between Fibonacci numbers 34 (order: 10) and 55 (order: 11)
import java.util.Scanner; public class While { public static void main(String[] args) { System.out.println("Welcome to the Fibonacci Sequence Detector");
Nearly all of hte sample Java Applet is pre-made by the teacher. I'm running into the issue where, if I use the string arithmetic inverse method provided by the textbook, it refuses to recognize variables such as s1, s2, and i. So I'm now trying to use stringbuilder, and running into a similar issue. It doesn't recognize hte symbol "buffer". Under the "else if ( e.getSource() == inverseStr ) {" is where my code starts. The "Your Code Here" was put there by the teacher, and I'm just using it as an easy way to create blank lines if I delete a method that isn't working for me in the above section.
import javax.swing. * ; import java.awt. * ; import java.awt.event. * ; public class HW07 extends JApplet { public void init() { setSize( 400, 300 ); add( new MyGUI() );
[code]....
When I launch the applet in TextPad, there will be an Inverse button, and when I click that, it should reverse the word provided in the applet window, and show it in the inverse there. I had the StringBuilder working once, but it showed its result in a separate command prompt.
I'm trying to write a program that counts the number of times each number in an array occurs. In theory I understand how it work, you take the first element in the array, compare it again the rest of the array and any time it occurs in the array you increment a counter by 1. Then move onto the next element A[1] and so on...
This is what I've done so far :
public static void main(String[] args) { int[] array = {5,6,2,5,2,2,0,1,6}; int count = 0; for(int i = 0; i <array.length; i++) { int val = array[i]; for(int j = i+1; j<array.length; j++)
[Code] .....
I think I'm on the right track as it correctly prints out the frequency of the first 3 elements, but I'm definitely going wrong somewhere as it just doesn't do it right after that!
I have a source code here that counts the frequency of alphabetic characters and non-alphabetic characters (see the source code below).
import java.io.*;
public class letterfrequency { public static void main (String [] args) throws IOException { File file1 = new File ("letternumberfrequency.txt"); BufferedReader in = new BufferedReader (new FileReader (file1));
[Code] ....
But, let's just say that now I have the following characters in the text file, "letternumberfrequency.txt": 71 geese - 83 cars - 58 cows- 64 mooses- 100 ants- 69 bangles- 90 molehills - 87 noses
The numbers inside that text file would be considered as strings, am I right? But I want to extract the numbers so that I can also be able to count their frequency - not as individual digits but as whole numbers (that is how many "71", "83", "58", "64", etc. are there...). Would using "Double.parseDouble ()" work?
Design and implement an application that creates a histogram that allows you to visually inspect the frequency distribution of a set of values . The program should read in an arbitrary number of integers that are in the range 1 to 100 inclusive; then produce a chart similar to the one below that indicates how many input values fell in the range 1 to 10, 11 to 20, and so on. Print one asterisk for each value entered.
No input prompt
Terminate input by typing CTRL/Z (two keys typed at the same time) on a separate input line (use CTRL/D on Linux/UNIX systems)
Use hasNextInt() to terminate your input
Format as below (slightly different from the text example)
Z:dbraffittWeek10> javac Histogram.java
Z:dbraffittWeek10> java Histogram
10 10 10 10 10 20 20 20 20 20 20
20 25 35 45 55 65 75 85 95
ctrl/z
1 - 10 | *****
11 - 20 | *******
21 - 30 | *
31 - 40 | *
41 - 50 | *
51 - 60 | *
61 - 70 | *
71 - 80 | *
81 - 90 | *
91 - 100 | *
What I can not figure out is how to use hasNextInt() to terminate the loop. How to not have an input prompt. How to use ctrl z to terminate the input. Or to make it where it doesn't involve range values like -1.

I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() { System.out.println("There are " + findUniqueWords(root, 0) + " unique words."); } private int findUniqueWords(Node subTree, int uniqueCount) { // Base Case: At the end of the branch if(subTree == null){ return uniqueCount;
How could I read an XML document from the web? I've seen people use SAX or DOM methods, but I've unable to make them work due to lack of experience so I would need a pretty brief overview not just 2 bits of code without any imports etc.
Also how would I be able to COMPARE the information? Like if it's " Sunny " I set a label text sunny etc.?!
I'm want to write a program to design single page documents. It needs the following features.Drag text and place it anywhere on the page, ideal I would like to add a 'snap to grid' optionDraw boxsAdd simple images (logos)
I plan to do it using Swing, but I've not done anything with this since finishing Uni. how to structure this and what swing components will be best suited for this task?
My current calculator (currently available on my site) launches your default webbrowser with the CalculatorHistory file allowing you to print through your browser, but I been working on self contain the html page in a the JEditorPane which is great it does what i want, so I started working on the printing side and I am stuck...
The code I have was from a example (modified) but when I run the code I get the following error:
Exception in thread "main" java.lang.IllegalArgumentException: services must be non-null and non-empty at javax.print.ServiceUI.printDialog(Unknown Source) at gcclinux.co.uk.PrintReport.main(PrintReport.java:28)
The Line 28 equals to PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
I have created a small application for editing text using StyledDocument and JTextPane. Now, you can set the font size, font colour, and other font related stuff. My question is, how could I save this document? What is the format? When I reopen this document, all the decorations I have done to the file should be there. How do I do this?
I have task for last years in campus , how do you scan document with scanner peripheral in java program? I have browsing on internet, and I have an API like TWAIN.
So - working on some new document composition tasks today, and realised my life would be made easier if I could have an application to allow me to compare two documents and highlight the differences...I know I could use a number of other tools, even word compare but it would be more fun if I could do it myself. Plus - there's the thrill of using non-approved technology at my workplace...I'm a maverick.
Just looking for the high level steps I should go through in creating an application which could be delivered to users in my team as an executable file (I have admin rights to my works laptop, but my direct reports do not have this on theirs) so would need to be able to run the app without installing if possible...
