Artificial intelligence (AI) still can't see the future,but a new algorithm (算法) may come close: using nothing but written movie summaries,AI can consistently tell which films will play well—or awfully—to critics and audiences.If the model can be further improved,it could one day help producers predict whether a movie will be a failure at the box office,before it's even made.
To test several AI models,researchers used plot summaries of 42,306 movies from all over the world,many collected from Wikipedia.The models broke the summaries by sentences and used something called sentiment (情感) analysis to analyze each one.Sentences considered "positive",such as "Thor loves his hammer",would receive a rating closer to a positive one.And sentences that were considered "negative",like "Thor gets in a fight" would be rated closer to a negative one.
Generally,successful movies such as 1951's Alice in Wonderland—which scored 80% on the movie-rating website Rotten Tomatoes—have frequent waves in sentiment;unsuccessful ones,such as 2009's The Limits of Control,vary less.It's not important whether the films begin or end happily,the researchers say.What's important is that the sentiment changes frequently.
The sentiment ratings in each summary were then simplified into a single score to reflect how often the sentiment changed.The researchers tested three different methods of arriving at a final score.All three could predict fairly accurately whether a movie would be unpopular,and one method worked especially well for guessing which thrillers and comedies reviewers would hate.
The methods were not as efficient at guessing which movies would succeed,but they still predicted the results more accurately than random chance.In the future,the researchers say their methods could be bettered to predict the amount a movie could earn at the box office and help producers decide which movies to invest in.The system's fair judgment might give an advantage to less well-known writers,the researchers add.It could also potentially save the public from having to sit through films like Jaws: The Revenge,which online critics and audiences alike rate as terrible.
Youth Art For Healing is a non-profit organization founded by Jan Papirmeister in 2012.As the Executive Director,she makes great efforts to work with schools,hospitals and other healthcare organizations to bring works of art created by the youth into healthcare environments.She wants to provide a sense of comfort,inspiration and healing for patients,their loved ones and healthcare professionals during very challenging times.
As a child,Papirmeister donated her artworks to a volunteer group caring for dying people and a camp for children with cancer.She felt pity for them so she hoped her works could bring a little help.When she grew up,she became a school nurse and showed students how to create drawings to decorate the walls of the health office.Then,as a hospital nurse,she made the time to sit with patients and create art with them.In her job as a nurse,she realized works of art could really help patients feel better.
Her organization Youth Art For Healing is based in Bethesda,MD.It provides opportunities for students to learn about the nature of healing art,the power of art to heal,how to follow guidelines for healing art,and the value of building and strengthening community connections and spirit.As students share their talent with those in need,they come to the realization that they can make a difference.
Papirmeister was awarded a Society for the Arts in Healthcare grant to bring artworks to patients,their family and hospital staff.She also received two SCORE Awards for her efforts to comfort patients and their family.This woman is a shining example of an artist and healer who uses the healing power of art to bring huge benefits to children,patients,their loved ones,healthcare providers,and the community at large.
