On the evening of July 19, the multilingual WebCrow crossword solver faced off against human experts in live and online session as part of the IEEE World Congress in held in Padua, Italy.
The WebCrow artificial intelligence software, developed by the University of Siena in collaboration with expert.ai, challenged professional crossword puzzle developers and solvers, computational intelligence experts, data scientists, crossword puzzle enthusiasts and students. WebCrow was put to the test by participants in both the Italian and English competitions.
How did it go? Let’s take a look at the results.
Artificial Intelligence prevailed at the live, multilingual competition where WebCrow stood out for its ability to solve crossword puzzles in both English and Italian with greater success in terms of quality and less total time to solve the puzzles.
A total of 82 human competitors took part in the Italian crossword puzzle challenge, including 35 in-person and 47 remote. WebCrow participated in 5 different versions, with a total of 87 participants.
For the challenge on American crossword puzzles, there were 58 participations, including 37 in-person and 21 online. WebCrow participated in 2 different versions, with a total of 60 participants.
The challenge on Italian crossword puzzles
Below are the rankings for the Italian (onsite and online) and English (onsite and online) competitions.
WebCrow placed 4th in the Italian challenge with online participants but still managed to come in second in terms of the “quality” of the proposed solutions, with only one incorrect character out of the two official competition schemes. The details of this error are shown below. Two competitors managed to beat WebCrow in the scoring based on speed of solving, but with one wrong character. Congratulations “Danilo” for solving the two crossword puzzles perfectly and in a remarkable time.
The challenge on American crosswords
When I heard the premise of this competition I was immediately inspired with a concept for a crossword theme. Around the idea of technological advancements there is often a bit of panic: computers are going to replace people, robots are going to replace people, artificial intelligence is going to replace people. I don’t personally think that’s likely anytime soon, but the thought did lead to the puzzle I wrote for this competition, entitled “AI Is Going to Replace People!!” The theme, in some ways, is one that might be tricky for a nonhuman solver, so I will be curious to see how it fares. I can’t say more about that without giving things away, but I can say that both I and Byron Walden — who composed the second puzzle for the competition, a themeless crossword — tried to write puzzles that would, ideally, be fairly accessible to an international audience while still giving the flavor of a modern American crossword. We hope you enjoy them! (Francis Heaney)
