Embodiments of the present invention provide systems and methods for automatically generating tag terms (or tags) for objects in databases of a web site. The metadata of the objects (or data) of the web site are processed and parsed to automatically generate tag terms for the corresponding objects. Information (or data, or content) downloaded from the Internet often comes with metadata, which can exist in titles, description, sources, and authors of the information, etc. The metadata of downloaded information can be process and parsed to generate tag terms for the corresponding objects. The system can automatically generate tag terms for the data, which are stored as objects in the databases, and make the data (or objects) searchable. In addition, the automatically generated tag terms allow associated data to maintain their relationship. For example, data from the same sources, same authors, or same subjects can be identified based on the common tag terms. Automatically generated tag terms enable searching and association of data (or objects) in databases in a web site.
