Abstract: In an embodiment, a set of related documents (105) is selected (305). Each document may include at least one table of data (107). The tables may not include semantic or structural data that can be used to understand the data in the tables. Each table is processed to determine a schema for the table that includes a name and type for each column of the table (320). A consolidated schema is received for a consolidated table (320). The consolidated schema includes a name and type for each column of the consolidated table. The data from each table is extracted from the table and added to the consolidated table based on the schema associated with the table and the schema associated with the consolidated table (325). Later, the data in the consolidated table can be visualized to help identify one or more trends (400).
