1. A method, comprising: analyzing a web browsing interaction history of a user associated with a given web page, the web browsing interaction history indicating that the user interacted with at least one element of the given web page; constructing a document object model (DOM) of the given web page; identifying, based on the analyzing, a node within the DOM corresponding to the at least one element in the given web page; identifying an ancestor node of the node; determining a distribution of node tag types for a set of child nodes associated with the identified ancestor node; and determining that the identified ancestor node comprises an item list including the at least one element within the given web page based on at least the distribution satisfying a given threshold, wherein each item in the item list corresponds to a child node in the set of child nodes, wherein determining that the identified ancestor node comprises an item list further comprises: determining, based on the distribution, a number of matching child tags associated with each of the set of child nodes, wherein each of the matching child tags is a structure based tag, and wherein a structure based tag affects a structure of a web page; determining if the number of matching child tags satisfies the given threshold; based on at least the number of matching child tags satisfying the given threshold, identifying the identified ancestor node as a candidate node comprising the item list; and based on at least the number of matching child tags failing to satisfy the given threshold, determining that the identified ancestor node comprises the item list.
