Claim 0:
1. A method, comprising:
for each document in a group of annotated documents:
extracting a set of words from the annotated document, and each of the words is positioned in a respective field of the annotated document; and
assigning a subset of the words as keywords;

using an aggregation function to determine, with respect to a first one of the fields, a similarity of each one of the annotated documents to all of the other annotated documents in the group;
creating a document layout graph that comprises nodes, wherein each node of the document layout graph corresponds to a respective annotated document, and each node is connected to all other nodes for which a similarity threshold for the first one of the fields has been met;
running a maximal clique algorithm on the document layout graph to identify a clique of the annotated documents, and each annotated document in the clique has a similar layout to respective layouts of the other annotated documents in the clique; and
performing, based on the group of annotated documents, an inference process with respect to a new document and, depending upon an outcome of the inference process, the new document is either added to the clique, or to another clique.
