Abstract
Desired content, metadata, or both can be isolated from the full content of social media websites having content-rich pages. Achieving this can include obtaining from the content-rich pages a language-independent representation having a hierarchical structure of nodes and then generating a node representation for each node. Feature vectors for the nodes are generated and a label is assigned to each node representation according to a schema. Assignment can occur by executing a trained classification algorithm on the feature vectors. The schema has schema elements and each schema element corresponds to a label. For each schema element, all node representations having matching labels are gathered and then one node representation is elected from among those with matching labels to be assigned to a schema element field in a template. The template can be applied to extract desired content, metadata, or both according to the schema from all the content-rich pages.
