| Abstract: | Digital transformation has been a source of advancement for many a field, including Risk Management. As the information flows grow, so does the ambition to convert unstructured data into insights. The focus has been limited, however, in the pursuit of isolating information of quality. This thesis aims to investigate potential indicators of information value through the scope of housing corporation risk management. The study objectives are achieved by the examination of potential information value indicators in literature and practice. To this end, the components of a housing corporation risk tool that act as a "filter" of valuable information, and can contribute to Ontology Learning, are developed. These components include a housing corporation risk ontology, a web crawler, and a text classifier. In the implementation phase, information that is crawled from digital news sources is classified as "housing corporation risk" or "not housing corporation risk" in multiple iterations. As the model is trained, we observe successful attempts in reducing information waste, but a challenge in identifying risk-related items with high accuracy. |
