Abstract:
1. A computer-implemented method for automatically updating a tag embedded in a webpage that summarizes a current version of the webpage, the method comprising: extracting, by a computing device, a first model representative of the current version of the webpage, the first model including nodes defining a hierarchy of elements of the current version of the webpage; comparing, by the computing device, the first model with a second model corresponding to a previous version of the webpage to detect one or more changes to the webpage; determining by the computing device, at least one keyword corresponding to the current version of the webpage if the changes exceed a threshold, wherein determining the keyword comprises: comparing, by the computing device, the keyword corresponding to the current version of the webpage with at least one keyword corresponding to the previous version of the webpage; and updating, by the computing device, the tag of the webpage to include the keyword corresponding to the current version depending on the comparison and the likelihood score.
