Generating and processing bilateral collaboration topic data

A computer-implemented method for preserving computing and network resources for communications between users, comprising:

• accessing a knowledge graph for a user, the knowledge graph comprising a plurality of nodes and a plurality of edges, the plurality of nodes corresponding to a plurality of contacts of the user and a plurality of data objects of the user, the plurality of edges corresponding to interactions between each of the plurality of contacts and each of the plurality of data objects;
• determining a set of contacts from the plurality of contacts of the knowledge graph for the user;
• determining a plurality of topics from the plurality of data objects of the knowledge graph for the user;
• for a contact of the set of contacts, determining at least one candidate topic from the plurality of topics based on corresponding interactions stored in the knowledge graph between the contact and corresponding data objects of the plurality of data objects;
• and
• responsive to at least one of navigating to the contact, a meeting with the contact and a communication with the contact, causing display of the contact with the at least one candidate topic corresponding to the contact.

One or more computer storage media having computer-executable instructions embodied thereon that, when executed by a computing system having at least one processor and at least one memory, cause the at least one processor to perform operations comprising:

• accessing a knowledge graph for a user, the knowledge graph comprising a plurality of nodes and a plurality of edges, the plurality of nodes corresponding to a plurality of contacts of the user, a plurality of data objects of the user, and a plurality of topics extracted from the plurality of data objects, the plurality of edges corresponding to interactions between each of the plurality of contacts and each of the plurality of data objects and relationships between each of the plurality of data objects and each of the plurality of topics;
• determining a set of contacts from the plurality of contacts of the knowledge graph for the user;
• for each contact of the set of contacts:
• accessing a subgraph of the knowledge graph, the subgraph of the knowledge graph comprising a set of nodes from the plurality of nodes and a set of edges from the plurality of edges corresponding to each contact;
• determining a set of candidate topics from the set of nodes based on corresponding interactions stored in the subgraph between each contact and corresponding data objects and corresponding relationships between the corresponding data objects and the set of candidate topics;
• ranking the set of candidate topics for each contact;
• and
• generating a number of topics for each contact based on the ranking of the set of candidate topics;
• and
• responsive to at least one of navigating to a particular contact of the set of contacts, a meeting with the particular contact of the set of contacts and a communication with the particular contact of the set of contacts, causing display of a first topic, from the number of topics, generated for the particular contact.
