Introducing @MentionMachine Social Index

@MentionMachine Social Index is a Washington Post news app that monitors Twitter for mentions of companies in the NASDAQ-100, revealing trends and spikes that show where the conversation is.

There are a few ways Twitter variables, or mentions, can be measured or extrapolated to examine trends. Growth in number of legitimate followers or a high recurrence of retweets are both indicative of growing grass-roots support. A spike in the number of times a company is mentioned on Twitter might signal an event that could alter the business day.

@MentionMachine Social Index displays the percentage change in the average in Twitter mentions for a company over a 24-hour time period, and ranks the 100 companies from most positive percentage change to least.

There are many engagement presentations across The Washington Post site that will display @MentionMachine Social Index counts to show these variables.

Toolbar — An overlay on Washington Post business content showcases the @MentionMachine Social Index ranking for each company in the NASDAQ-100. This shows what company had the greatest positive percentage increase in Tweets in a moving 24- hour window relative to their norm.

Company pages — Data-rich displays for each company in the NASDAQ-100 that include interactive charts detailing Twitter trends and spikes over the past 24 hours, along with a stream of the latest news on the company and navigation to its relative financial data.

Company comparisons — A leaderboard tracks Twitter mention “scores” by percentage change from norm for each company in the NASDAQ-100.

Methodology and Functionality

@MentionMachine Social Index was developed exclusively by The Washington Post. It leverages the Twitter streaming API to capture and analyze Tweets that include the company ticker symbol. The exception is for Electronic Arts and CA Technologies as these ticker symbols are too commonly referenced in other contexts. The app is searching for their full company name mentions.
