Dark data is often just untapped data that can be valuable but is not recovered because of a lack of resources, skilled analysts and the sheer volume of dark data that exists. Now because of big data and AI tools, Machine Learning and data mining techniques, precious insights and a treasure trove of information can be excavated from dark data and turned into optimized data. Software such as RPA (Robotic Process Automation) automates and streamline operations. Dark data needs to be tended to regularly and organized within the repository.
Data analytics is traditionally linked to structured data but dark data analytics is the process of unearthing untapped data to find hidden opportunities. Dark data analytics sifts through three categories of information; traditional instructed data that already organizations have already stored (i.e. emails, documents); non-traditional unstructured data are usually media assets that cannot be processed through big data methods; and huge volumes of data found in the deep web which is curated from a variety of sources (government agencies, third-party domains, etc.).
Organizations should monitor dark data for the following factors:
