Tier: 1-Beginner
Calculating the frequency of words in a block of text is a technique which has various uses in algorithms such as searching, sorting, and semantic analysis. The objective of the Word Frequency app is count the frequency of words in a block of text and create a tabular display of each unique word in the text along with its frequency, in descending order by frequency.
- User can see a text input box, a 'Translate' button, and a word frequency table.
- User can enter text (or cut and paste) into the input box. This input box must allow the entry of large blocks of text (maximum of 2048 characters).
- User can click the 'Translate' button to analyze the word frequency in the text that has been input.
- User can see an error message if the text input box is empty.
- User can see the word frequency table populated when the 'Translate' button is clicked. Each row in the table contains a word and the number of times it occurs in the input text.
- User can see the word frequency table ordered in descending sequence by word frequency.
- User can see a graphical representation of the word frequency in a bubble chart, column chart, or any other form of graphical representation the developer chooses.
- User may choose to enter the URL of a web page whose content is to be analyzed instead of manually entering text. (Hint: See the Podcast Directory application for ideas).
