Originally an enterprise search and discovery tool for SharePoint, Delve is a mix of search, social networking, and machine learning. Delve connects workers through social feeds, content, and activities. This is done through personalized profiles as well as machine learning to assess which projects are likely relevant to employees.
Delve departs from Microsoft’s previous approaches for search and discovery in the enterprise. With this departure, you get a unified and secure interface for working with all the resources that your Office 365 users have access to e.g., SharePoint, OneDrive for Business, Office 365 Groups. The interface is dynamic, personalized and interactive. Searches can be based on content, activities and relationships. Users can also locate content by accessing the activity feeds of coworkers who have worked with a particular item.
