Word Guess Game

What is the word?

Java

  • In this project, I developed AI-based guessers and word choosers for the game "Awakening of Azathoth," gaining hands-on experience with Java's built-in List and Map data structures.
  • I successfully created three distinct AI guessers that could play the game, along with two innovative word selection classes that elevated the complexity of the problem.
  • This project showcased my ability to utilize data structures effectively, and allowed me to demonstrate my proficiency in Java programming.

Words Map

Connecting...

Java

  • I developed a browser-based tool for exploring the historical usage of words in English texts. Utilizing a subset of the Google Ngram dataset, I built the back-end in Java to analyze word frequencies over time, focusing on individual words (1grams).
  • The project involved implementing various data structures and working with the WordNet semantic lexicon, which groups words into synsets and describes semantic relationships between them.
  • By harnessing the power of WordNet and data analysis techniques, I successfully created a functional tool that allows users to visualize the relative historical popularity of words in a clear and comprehensive manner.
