Block Duplicate Work Items

This extension provides the ability to block duplicate work item creation, similarity between work items is currently determined based on Dice's Coefficient.

Checks are automatically performed on work items of the same type | all types and on the following fields (configurable from the project's admin hub) :

• Title
• Description

As we are more interested in the textual content before performing our similarity check we normalize our text:

1. Removing all HTML tags.
2. Removing the following punctuation !"#$%&'()*+,-./:;?@[\]^_`{|}~.
3. Convert to lowercase.

Similarity is established based on an index 0.0 - 1.0 :

• 0.0 being least similar
• 1.0 being most similar.

By default this extension leverages a default threshold of 0.80 for similarity index, this threshold is configurable from the project's admin hub.

This extension can be leveraged in combination with the Find similar workitems extension to establish which work items are similar to the current item.
