In an automatic context adaptive search and result generation, a server obtains an email corpus of a user for a current time period. The server identifies a set of triggering semantics in the email corpus, and using an ontology, identifies a set of topic-context pairs corresponding to each triggering semantic. The server identifies a set of paths in the ontology activated by the set of topic-context pairs and compares the set of activated paths with paths in each heatmap of a set of heatmaps, where each heatmap corresponds to a document in a set of documents. The server identifies one or more heatmaps of the set of heatmaps including one or more paths matching an activated path of the set of activated paths. The server then outputs a search result including the one or more documents corresponding to the one or more heatmaps.
