Personalized content suggestions in computer networks

A computing system, comprising:

• a processor;
• and
• a memory containing instructions executable by the processor to cause the processor to:
• upon receiving, via a computer network, an indication to perform a search for content items from a member of an organization having multiple members,
• identify a first node corresponding to the member in an interaction graph associated with the organization, the interaction graph having multiple nodes individually representing one of the members or a content item accessible within the organization, individual pairs of the nodes being interconnected by an interaction indicator representing prior interaction therebetween;
• identify, according to a first level of indirectness, a set of second nodes indirectly connected to the first node via multiple interaction indicators in the interaction graph;
• determine whether a number of the second nodes in the identified set is below a preset threshold;
• in response to determining that the number of the second nodes in the identified set is below the preset threshold, regenerating the set by querying the interaction graph according to a second level of indirectness higher than the first level of indirectness;
• and
• present at least some of the identified second nodes in the regenerated set as a search suggestion to the member via the computer network.

A method for providing personalized content suggestions in a computer system accessible to multiple members via a computer network, the method comprising:

• upon receiving an indication to perform a search from a member,
• identifying the member as a node on an interaction graph having interconnected nodes individually representing one of the members or a content item and linked by interaction indicators representing prior interactions therebetween;
• identifying a list of content items linked to the node representing the member in the interaction graph, wherein at least one of the content item in the list corresponds to a node that is indirectly connected to the node representing the member in the interaction graph via one or more intermediate nodes;
• determining whether a number of the content items in the identified list is below a preset threshold;
• and
• in response to determining that the number of the content items in the identified list is not below the preset threshold, presenting at least some of the content items in the regenerated list to the member via the computer network.
