Domain scoping for subject matter experts

Abstract

Exploring web and in particular social media data is an essential task to many of the subject matter experts in order to discover content around their subject of interest. It is important to provide them with a tool to define their scope of vocabulary, i.e what to search for, and suggest them commonly used terms besides the serendipitous terms allowing them to define their scope of explorations. This paper presents methods on constructing "domain models" which are families of keywords and extractors to enable focus on social media documents relevant to a project using multiple channels of information extraction.
