The platform not only measures how many mentions companies get online, but also uses sentiment analysis to measure brand perception, to see just what those mentions are actually saying. To measure sentiment, has turned to Lexalytics, a vendor of a sentiment and intent analysis platform.

PR crisis

Sentiment analysis is "a very important tool when dealing with any kind of PR crisis," Bubele said.

By combing through what's being said online during a crisis, like the PR crisis around the delayed Iowa caucus results right now, brands can monitor how well public relations efforts are working. They can measure if efforts are intensifying the crisis or making it worse and can then adjust strategies accordingly.

Using Lexalytics, can automatically perform sentiment analysis. Lexalytics, founded in 2003 and headquartered in Amherst, Mass., supports 22 different languages with dozens of machine learning models per language, said Paul Barba, chief scientist at Lexalytics.

The challenges with automatic sentiment analysis in marketing, Bubele said, don't necessarily lie with Lexalytics, but rather with the technology in general.

"Sentiment is definitely not an exact science," Bubele said. It's difficult to teach a machine sarcasm or slang, for example, especially over text.

News articles are particularly tricky to automatically perform sentiment analysis on, Bubele said, as they can contain numerous negative and positive statements about a company in one article. Even for a human, it can become difficult to assign a positive or a negative sentiment to one news story, she said. 

"It's a bit of a hit or miss, but the general trend is quite clear," she said. Individual social media posts, news articles and blog posts can be difficult to automatically pull sentiment from, but, given enough posts or articles, a picture becomes clearer.

Over the last few years, the Lexalytics platform has gotten better at picking out sentiment, and it has added support for more languages, which has been positive for, which supports around 20 languages, said Bubele. Since partnering with Lexalytics, the company hasn't considered using another tool.
