Abstract: Described are methods and systems to identify missing connections, facilitate establishing new connections by identifying an intermediary, and present the intermediaries and missing connections as an ordered set based on the connection criterion. According to various embodiments, the system receives a selection of a connection criterion from a first member and identifies a set of contact members. The system determines one or more contact members from the set of contact members and identifies a set of introduction members connected to the one or more contact members. The system determines one or more connected introduction members associated with the contact members. The system generates a contact order score for each contact member and causes presentation of the one or more contact members and the one or more connected introduction members based on the contact order scores.
