The Minutovka – a Word Typing Web Game for Obtaining Typos to Create an Error Corpus

The paper describes the web application of a simple typing game, which we designed and implemented mainly to obtain typos and create an error corpus. We created the game for the Slovak language, as we lacked such data. However, it could be used for languages other than Slovak. We called it Minutovka (in English “One minute game”) because we set the maximum duration of the game time to one minute. During this time, a player must rewrite the words from the randomly displayed sentences as quickly as possible and with as few errors as possible. On the one hand, the player is motivated to get the highest score and beat other players in the daily, weekly, or overall rankings, while improving his typing on the keyboard. On the other hand, our motivation was to obtain data on how users write and especially what typos and errors they make during the transcription of the text. In this paper, we describe this game from the design to the implementation, including issues that have occurred during the operation of the game. We also designed fraud protection and implemented it with the proposed hacker score. At the end, we evaluate and visualize all the obtained data, which we store in the document-based database MongoDB.
