Many WordPress installs suffer from cramming hundreds or thousands of varied taxonomy terms in to a limited number of ill-suited, all-purpose taxonomies (eg. the default “categories” and “tags”).
These are better off split in to dedicated taxonomies. For example, storing “Bill Gates” and “Microsoft” terms in “tags” is not optimal, because one is a person whilst the other is a company.
There is no straightforward way to split up existing taxonomies more granularly in this way, except for labour-intensive and manual, technical effort. So, many WordPress installs continue to suffer from not having created granular taxonomies intentionally at the outset.
Term Tidier tidies up messy taxonomies like these automatically. It uses natural language processing and knowledge graph technology to determine the real <a href="https://gcloud.readthedocs.io/en/latest/_modules/google/cloud/language/entity.html#EntityType" rel="nofollow ugc">entity type</a> of existing terms, then re-assigns them each to a more appropriate, alternative taxonomy.
<h3>How it works</h3>
Term Tidier uses Google Cloud’s Natural Language Processing features via API calls.
Users set a “source taxonomy”, the taxonomy they want to be tidied up.
For each term within that taxonomy, Term Tidier calls Google Cloud to examine the term name, aiming to return a determination as to its true “entity”.
The plugin receives one of eight “entity” type determinations from Google Cloud – UNKNOWN, PERSON, LOCATION, ORGANIZATION, EVENT, WORK_OF_ART, CONSUMER_GOOD or OTHER.
For each entity type, users specify a target taxonomy to which a matching term will be moved. For example, you can map all terms found to be a “LOCATION” to your own “Places” taxonomy, if it exists.
For each term in the source taxonomy, if a particular entity was determined, Term Tidier moves the term to your corresponding taxonomy.
<h4>Usage</h4>
Use Term Tidier from the WordPress Tools menu (Tools > Context Term Tidier).
The plugin page confirms your settings as set in Settings, displaying the taxonomy and terms which will be examined.
Click the “Tidy Terms” button to execute the operation.
Term Tidier will cycle through each term, seeking an “entity” determination and re-assigning any terms possible.

Through the use of the WordPress custom Taxonomy API you can add sub categories to your posts such as eCommerce, Books or Plugins. 
This can be especially useful if you have an eCommerce platform which uses custom post types in conjunction with custom taxonomies.
<h4>Custom Taxonomies</h4>
In case you are not familiar with custom taxonomies there are two parts when you create a custom taxonomy. 
There is the taxonomy itself and the terms associated with that taxonomy. So for the Tag taxonomy, for example, 
the taxonmy is Tag and the terms are the tags which are added to posts. In the case of categories the taxonomy is 
Categories and the terms are each category value which have beed added.
<h4>Features</h4>
The features of the Toolkit are :-
<ul>
<li>Bulk removal of terms from posts</li>
