Hi,
As mentioned in the Knowledge Base article [**Twitter, sentiment analysis and Denodo**](https://community.denodo.com/kb/view/document/Twitter,%20sentiment%20analysis%20and%20Denodo?category=Custom+Elements), to apply sentiment analysis within Denodo, you need to create a custom function using the Denodo4E plugin.
The Denodo Express license has some limitations compared to a full license which imposes that importing extensions (jars) is **not allowed** in Denodo express. Hence it is not possible to develop\import custom connectors to sources, custom policies or custom functions in the Denodo Express.
You can also refer to the section [**Limitations of the Denodo Express License**](https://community.denodo.com/docs/html/browse/7.0/platform/installation/appendix/limitations_of_the_denodo_express_license/limitations_of_the_denodo_express_license#limitations-of-the-denodo-express-license) of the Denodo Platform Installation Guide for more information.
On the other hand, the **Denodo Templates for Twitter** provides quick and easy access to tweets, users, messages and other data accessible through a Twitter API account and you can download it from the Denodo Support Site under “**Downloads > Denodo Connects**” option only if you have a valid Denodo Support account.
However in Denodo Express, if you would like to integrate to twitter from Denodo, then you create a JSON data source using the Twitter API. In order to do so, you perform the steps as mentioned in the section [Connecting Twitter and the Denodo Platform](https://community.denodo.com/kb/view/document/Twitter,%20sentiment%20analysis%20and%20Denodo?category=Custom+Elements) of the Knowledge Base article Twitter, sentiment analysis, and Denodo.
Hope this helps!
