Abstract: Calculating a failure intensity value for a group of search sessions is provided. In one example, a method for calculating a failure intensity value for a group of search sessions is provided. The method includes obtaining, by a computing device comprising a processor device, the group of search sessions, where each search session of the group of search sessions includes user input that identifies a search query. The method further includes classifying each search session of the group of search sessions into one or more result categories, where each result category is indicative of an outcome of a search session. The method additionally includes calculating the failure intensity value for the group of search sessions based on a combination of weighted values of the group of search sessions, where the weighted values are based on the one or more result categories of the group of search sessions.
