14. A method to improve results of a search query, comprising: selecting, by at least one computing device, as at least one utility node, a first subset of a plurality of taxonomy nodes of a catalog of items based at least in part on a plurality of utility scores corresponding to the plurality of taxonomy nodes, the plurality of utility scores being based at least in part on a user interaction history of an electronic commerce system with respect to the search query; selecting, by the at least one computing device, as at least one relevant node, a second subset of the plurality of taxonomy nodes based at least in part on a plurality of relevance scores corresponding to the plurality of taxonomy nodes, the plurality of relevance scores being based at least in part on the search query; selecting, by the at least one computing device, at least one of the plurality of taxonomy nodes according to a convergence of the at least one utility node and the at least one relevant node as the improved results of the search query; and communicating, by the at least one computing device, an indication of the at least one of the plurality of taxonomy nodes to a client device facilitating a browsing of the catalog of items responsive to the search query and a selected one of the at least one of the plurality of taxonomy nodes.

The method of claim 14 , further comprising determining the convergence by: excluding, by the at least one computing device, from the convergence, a descendant node included in the at least one relevant node and excluded from the at least one utility node, the descendant node having an ancestor node in the at least one utility node; and including, by the at least one computing device, in the convergence, the ancestor node.
