aziyan99/SwiftTfIdf

An ordinary swift package, have a bunch looping of calculating TFIDF

Take a peek

Install

Just install like usual, using swift package manager

  1. File > Add Packages...
  2. Paste https://github.com/aziyan99/SwiftTfIdf in the search form (top-right)
  3. Choose the first one SwiftTfIdf with main branch

How to use

Use it like usual, no magic here (magic will be add in the future :v)

  1. import the package import SwiftTfIdf
  2. Instance it let tfIdf = SwiftTfIdf(text: String, stopWords: [String], topN: Int). text is the raw text that need to be ranking, stopWords the stop words (array of String), and topN how much the top words that want to get.
  3. Call the .finalCount() function to get the results let results = tfIdf.finalCount(). The funcion will returning array of dictionary [(key: String, value: Float)] with key is the words and value is ranking value.

How it works

The calculation happend base on looping and sequentials, splitting the text to a bunch of array of sentences and words, calculate the tf, calculate the df and the tfidf, sorting the results, and ranking it. That means the more words that are processed the longer the execution time. An example of implementation will be adding soon. <br /> <br /> <img src="https://i.redd.it/4npl9yfg5js11.jpg" alt="https://i.redd.it/4npl9yfg5js11.jpg" style="height: 300px; width:300px;"/>

Todo

  • [ ] Writing the test case
  • [ ] Adjust & improving the looping performance
  • [ ] Restructuring the code
  • [ ] Improve time complexity
  • [ ] Adding logo (maybe will make it cool :v)
