The authors: Sep Kamvar, left, a computer scientist, and Jonathan Harris, an artist with a computer-science background, have used their computer and visual arts skills to mine the Internet for human feelings. The two collaborated on an interactive installation, "I Want You to Want Me," that explored people's search for love in the world of online dating (it was exhibited by the Museum of Modern Art). "We Feel Fine," originally a Web site (www.wefeelfine.org), is their latest joint project. Kamvar is a consulting professor of computational mathematics at Stanford University. His research focuses on data mining and human-computer interaction. Harris' projects range from building the world's largest time capsule to documenting an Alaskan Eskimo whale hunt. New York Arts Magazine has called him a "Renaissance man for the information age."


The book: In 2005, the authors wrote a computer program to scour blogs every few minutes, taking sentences that have the phrases "I feel" and "I am feeling" in them. They have collected more than 12 million feelings, amassing an ever-growing database of human emotion that adds more than 10,000 new feelings a day on their Web site. They track, when possible, the age, gender, weather, and location of the bloggers. With photos and quotes from the blogs, the book features some of the most moving vignettes and trends the program found on the 50 most common emotions, including fear, loneliness, shame, and pride. The book also includes the authors' observations based on statistical analysis of the data. Kamvar and Harris found, for example, that people get happier and more grateful as they get older, and that women "verbalize their emotions far more frequently than men do, and when men do verbalize their emotions, they often express them in a more attenuated manner." One infographic maps the states that report feeling the most happy, lonely, sick, and fat.

From the book: Observations about feeling awful: "When people talk about feeling awful, it is most common for them to talk about feeling physically awful. It is usually mentioned when they are feeling sick, or when they have the flu, a fever, a headache, or an infection. It is also very common for people who feel awful to say that they wake up feeling awful. People also frequently say that they feel awful for breaking up with somebody who loves them. And people also feel awful for forgetting the birthday of someone who is close to them."

Reviews: The Fort Worth Star Telegram called the book "a collection of hope, sadness, and grievance that can be seen as a global Rorschach." Dailycandy.com said that "sentiments spring to life via pages of user-contributed emotions and accompanying photos." By Katherine Federici Greenwood
