Information Retrieval from Unstructured Sources

Hi Guys, A PhD student in civil Engineering here. I'm bit of a stuck in my research. As objective 1 I tried to carry a Qualitative Research to understand why construction professionals resist the technology. I found out that they don't even understand what structured data and unstructured data is. Anyways I proposed a solution that should not be technically difficult. I came across a paper" Using semantic documentation to management software project management" and proposed I could use it. I think I was pretty clear that I'm improving Semantics in the data and aim to improve data integration and information Retrieval.But the committee has asked me I need to be more specific what to do, improving data Accessibility, availability or what. I'm really confused in this part. My supervisor is a civil engineer and doesn't understand himself, therefore I'm here
