New Academic Study from Lithium Technologies' Data Science Team Identifies Expertise Across Social Networks


SAN FRANCISCO – September 8, 2016 – An academic research paper by the Lithium Technologies data science team, “Mining Half a Billion Topical Experts Across Multiple Social Networks,” has been published in the Social Network Analysis and Mining Journal. Analyzing and ranking topic experts across Twitter, Facebook, LinkedIn and Google+, the study analyzes more than 12 billion messages and ranks 500 million experts on more than 9,000 topics. This expert ranking system flows directly into Lithium’s products, allowing brands to better understand their Total Community of customers. It also offers brands a way to identify what social networks specific topic experts are engaging on.

“We’re drawing the line between social media popularity and credibility as our team of data scientists map out the social web, tapping into the wealth of data at their disposal,” said Sunil Rajasekar, CTO, Lithium Technologies. “We’re happy to make the methodology and results available to further the discipline. There’s still lots to be done as new social channels rise in prominence and more and more people come online, but we’re up to the task.”

“Brands need to evolve past simply trying to reach the people with the most followers, or taking a scattershot approach of engaging with anyone and everyone on digital channels,” said Rob Tarkoff, President and CEO of Lithium Technologies. “We’re making it easier for brands to identify the right experts for their product or service but that’s just the first step – they then need to work on cultivating authentic relationships with them.”

Since acquiring Klout in 2014, Lithium has been working to integrate its wealth of data across its entire portfolio of products to help businesses connect, engage and understand their Total Community. Specific examples pertaining to the topic experts data include:

  • Profile Plus in Lithium Communities – leveraging topic experts data science, brands can personalize the community experience based on member interests and expertise, and identify top influencers by topic
  • Lithium Response – brands can intelligently route and prioritize customers’ questions and complaints based on their topic expertise, giving consumers more relevant and personalized service in a timely manner.
  • Lithium Reach – Reach’s data-driven recommendations empower brands to publish content their customers want. Early results show that this leads to a 25% increase in engagement.
