Systems and methods for organizing and identifying documents via hierarchies and dimensions of tags

An apparatus comprising:

• a memory device that stores a set of instructions;
• and
• at least one processor configured to execute the set of instructions to:
• access, via one or more data storage devices, an object model, wherein:
• the object model comprises cells, relationships among the cells, and combinations of tags and tag values associated with the respective cells,
• data items are associated with cells of the object model based on corresponding combinations of tag values associated with the respective data items, and
• relationships among the cells are based at least in part on relationships among tag values of tags associated with the cells;
• receive, via a user interface, search criteria for searching the plurality of data items, wherein the search criteria include indications of one or more tags;
• and
• responsive to receiving the search criteria:
• determine a first cell of the object model matching the one or more tags indicated in the search criteria;
• determine a second cell of the object model that is related to the first cell based on a relationship indicated by the object model;
• identify at least one or more data items associated with the second cell;
• and
• provide, for displaying in the user interface, indications of the one or more data items associated with the second cell.
