Frog launched a website that allows you to explore the last 25 years of news in Portugal, through the archives of the agency Lusa and articles for various websites, totaling seven million texts.
The tool, called Time Machine and developed by the Faculty of Engineering of the University of Porto in partnership with Frog Labs, lets you search by a person (the politicians to footballers) to see all items in which this person was referred, access a list of quotes that the media did and still see a network of relationships with other personalities. Are indexed about 100 thousand people.
A survey by Pedro Passos Coelho, for example, shows that it was mentioned in 25402 since November 28 last year, a period during which the prime minister was cited 3313 times by the media. The web of relationships (calculated from the frequency with which other persons also appear in articles in which Pedro Passos Coelho is mentioned) shows that Paulo Portas is the strongest bond – meaning that the Deputy Prime Minister is the figure that more often appears in news which also include the prime minister. Other common names are António José Seguro and Aníbal Cavaco Silva.
project leader, Benjamin Jr., says that one of the objectives is now to embed photos and videos. “I want people to surf at 20 years of photos of Mário Soares,” he explains. Use images raises, however, new challenges classification.
For elements such as text or photographs may be used in Time Machine, they must have associated information that computers can interpret as a date. But many of the photographs that the project will come to show do not have enough information associated. Therefore, the team Time Machine is to develop algorithms to recognize faces, objects and patterns, so that a computer can automatically identify stakeholders and to try to determine the date of a photograph, photographed from the elements and any information that exists in the legends of the image.
tool now available had been shown last year at Toad Codebits, event programming and technology at PT.
The Time Machine also shows the most frequent figures in the news in recent days. Over the last week, the list is led by Cristiano Ronaldo, mentioned in 804 articles. Here are Cavaco Silva, Mário Soares, Paulo Fonseca (Porto coach), Pedro Passos Coelho and Benfica coach Jorge Jesus.
