A Content Model is the digital representation in Grooper of a document set's content. What content you want to glean from your documents is all set up within a Content Model, including the system for classifying documents and what data you want to extract from them.

Content Models are the fundamental Content Type.  Other Content Types, such as Document Types, are established within a Content Model.  Content Models have two main purposes in Grooper:  

• Document Classification
• Data Extraction

Let's look at how Document Classification and Data Extraction can be used on a Content Model:

Document Classification is an important task that the Content Model helps facilitate.

The very first property of a Content Model is the Classification Method. This tells Grooper how to classify documents. This can be done one of five ways: GPT Embeddings Labelset-Based Lexical Rules-Based Visual

Another important tenet of classification that is relied upon by both Grooper and the Content Model is the Document Type. This is a child object of the Content Model that is used to identify certain documents through positive extractors. For more information on Document Types, click here: [1] For Documents that are more difficult for Grooper to classify, or if you don't want to set up a Classification Method, you can set a Default Content Type. This is optional. If you have multiple Document Types, it's best just to set a Classification Method on the Content Model. You will need to have a Document Type created in order to do so.

FYI	GPT Embeddings is a fairly new Classification Method and is still currently in beta.

Content Models define the classification taxonomy for a set of documents.  This means a list of distinct types of documents (via Document Types), their hierarchical structure within the Content Model (via optional Content Categories). How a document is classified is defined here as well (via the Classification Method and the Document Types).  

Hand-in-hand with the classification taxonomy, Content Models also define the hierarchical data structure for the documents and document set (via Data Models of the various Content Types in the Content Model). The Data Models and their Data Elements define what data is extracted from documents and how that is accomplished.
