1. A method comprising: receiving text associated with a content item, the text including a plurality of term strings, each term string including one or more terms; determining, by a computing device, a set of relevance intervals for a corresponding set of terms in the text, wherein each relevance interval of the set of relevance intervals identifies one or more sections of the content item that are relevant to a corresponding term; generating a first set of nodes for a first term string from the plurality of term strings, wherein the first set of nodes includes a node for each term in the first term string, and at least one node for a term different from the terms in the first term string but whose corresponding relevance interval includes the first term string; generating a second set of nodes for a second term string from the plurality of term strings, wherein the second set of nodes includes a node for each term in the second term string, and at least one node for a term different from the terms in the second term string but whose corresponding relevance interval includes the second term string; and determining a plurality of connections between nodes in the first set of nodes and the second set of nodes, wherein the plurality of connections includes a subset for a first node from the first set of nodes, wherein the subset for the first node includes a connection for each node from the second set of nodes; and using the first set of nodes, second set of nodes or plurality of connections to identify one or more segment boundaries within the content item.

The method of claim 1 , wherein a first connection of the subset for the first node is a connection strength that includes a contextualized measurement of the relatedness between the first node and a second node in the second set of nodes.
