Methods, systems, and computer program products for structured representation and classification of noisy and unstructured tickets are provided herein. A method includes correlating one or more items of problem incident text data from a given problem incident identifier with items of event text data to generate items of correlated text data within the given problem incident identifier; applying a syntactic grammar to the items of correlated text data to identify in the given problem incident identifier (i) one or more domain-dependent concepts and (ii) one or more domain-independent concepts; parsing noisy and/or unstructured text from the given problem incident identifier based on analysis of (i) the domain-dependent concepts and (ii) the domain-independent concepts; and classifying the given problem incident identifier by classifying features derived from text of the given problem incident identifier subsequent to said parsing of said noisy and/or unstructured text from the given problem incident identifier.
