Abstract
An online system generates a taxonomy to classify objects that resemble each other. To compare different objects against each other, the online system generates canonical form data structures to represent the objects. The online system uses the canonical form data structures to standardize unstructured information about objects, for example, objects received from different sources of information to generate the taxonomy. The online system can determine a level of resemblance between objects based on parameter values of the canonical form data structures. The online system uses the taxonomy to exclude content items that are unlikely to be of interest to a user of the online system. The taxonomy may be represented by a graph data structure including nodes connected by edges.
