I created an influencers analytics solution some years ago (tribalytics.com), and Social Network Analysis (SNA) applied to people's followers got us much better results: Instead of analyzing a twitter user's bio, we would also cluster their followers into communities (according to how they follow each other), then summarize each community's characteristics. This gave us multiple accurate segments allowing to qualify a person
e.g.:
* 35% marketing and social media professional
* 10% foodie
* 15% kayak fan
* etc...
I'm not active anymore on this solution though, as that analysis was quite expensive and too complex for what our target customers marketers were looking for...
Also who are the big leaders in the influencer search tool space these days?

I'm a bit rusty as the landscape evolves quickly, and I'm not much active anymore on the influence marketing sphere. Two actors which look relevant to me:
