Pheme (project)
Pheme is a 36-month research project into establishing the veracity of claims made on the internet.〔(【引用サイトリンク】url=http://www.telegraph.co.uk/technology/social-media/10647974/Scientists-develop-a-lie-detector-for-tweets.html )〕
==Introduction==
Unverified content is dominant and prolific in social media messages. While big data typically presents challenges in its information volume, variety and velocity, social media presents a fourth: establishing veracity. The Pheme project aims to analyse content in real time and determine how accurate the claims made in it are.〔(【引用サイトリンク】url=http://news.sky.com/story/1214023/scientists-plan-lie-detector-for-tweets )〕 As claims propagate through a social network, each individual chooses whether or not to pass on information, based on how accurate they think it is. Analysing the language used and the spread of information through a network, as well as the spatial and temporal context of the information, is used to build a real-time lie detector for social media. This will help, for example, emergency services (who already integrate social media as part of their alerting and response systems) to flag potential hoax emergencies.〔(【引用サイトリンク】url=http://www.arabnews.com/news/528436 )〕
Evaluating the authority of sources automatically is also a project goal, based on the treatment of the news and information that comes from them. For example, a tweet of a BBC news article would hold more weight than one from an unknown source.〔(【引用サイトリンク】url=http://www.engadget.com/2014/02/19/twitter-lie-detector/ )〕
The project is named after the Greek goddess Pheme.
