David Cameron was the most tweeted-about politician over the last seven days, but his Tory party was tweeted about less than Labour, Ukip and the SNP, according to ElectUK big data app.
The app, created by Tata Consultancy Services (TCS) to demonstrate the power of big data tools to business, was launched last week.
It found that Cameron has been the most talked-about politician on Twitter, with 20.6% of all mentions, followed by Ed Miliband with 18.3% and Nigel Farage with 4.9%.
Grant Shapps, Simon Danczuk and Alex Salmond were other politicians trending on Twitter over the past seven days.
In terms of the most talked-about parties, Labour was top with 31% of tweets mentioning it, Ukip was close behind with 29.1%, followed by the SNP with 19%, then the Conservatives in fourth place.
The most tweeted general election issues were healthcare (30%), the economy (27%) and Europe (13%).

The app is free to download and is available on iOS and Android devices. It uses TCS-developed big data analytics software known as PeriVista and provide dashboards of information about the parties, candidates, political commentators and political issues.
The PeriVista big data platform crunches the numbers every 30 minutes and presents them to users in graphs and infographics. It will also have a live feed from Twitter, with tweets and the location they were sent from revealed in near-real time.
It has analysed more than 4.1 million tweets around the election so far.
TCS UK head Shankar Narayanan told Computer Weekly recently that the app demonstrates what technology can do with unstructured data. He said enterprises are using big data on an ad-hoc basis with different departments trying it out, but eventually enterprises will adopt it more formally.
Retailers are particularly interested in harnessing unstructured customer data from sources such as social media, but any company that supplies consumers can gain valuable insights, said Narayanan.
