Such an approach will also miss what might be termed secondary messages from other sources, such as eye-witnesses, who may provide interesting and informative details about a story. A similar problem occurs with a second possible option, namely using keywords (including hashtags) to filter incoming messages. This recasts the task as a search task with the attendant risks: all tweets that contain the search terms will be retrieved, including repetitions and redundant messages, while tweets that are relevant but do not contain the specified terms will be missed.

The variation is likely due to the different nature of the two matches considered and the volume of tweets generated. Repeating over more matches would give us a clearer indication of quality, but clearly the algorithm does find a large number of the most important events. Other systems have been proposed to discover events within sporting fixtures, but these typically are designed to find only events of pre-defined classes, such as goals or bookings [42, 43]. In contrast, ours is agnostic about the specific nature of the event, relying only on shifts in the word-use used by multiple users to describe it.

The scale and diversity of these sites raise the question: how can users (whether journalists or non-professional “news consumers”) find newsworthy topics from sites such as Twitter? One option would be for them to simply identify and follow some Twitter accounts that tend to Tweet regularly about the news, such as @CNN or @BBCNews. This approach has drawbacks however. Major news organizations tend to follow similar agendas, meaning that when an event occurs, either all the accounts will send equivalent messages, flooding the user with redundant messages, or none will send messages and the consumer will never learn of the story.
