A meta-engine for building domain-specific search engines

In recent years, domain-specific search (DSS) has emerged as a growing and important area of applied research in artificial intelligence (AI) and information retrieval (IR). Over the last 6 years of research, our group has developed a 'meta-engine' called myDIG (my Domain-specific Insight Graphs) that provides a relatively easy and customizable workflow for building DSSs without advanced technical training in crawling, information retrieval or user-interfaces. The myDIG system has been applied to some important and difficult use cases (most notably, fighting human trafficking), in addition to being used in classrooms by graduate students for building complex DSSs from scratch.
