MeaningCloud
The Qlik MeaningCloud connector uses the Sentiment Analysis API to fetch the sentiment score for a text. The Sentiment Analysis API returns other sentiment information such as, subjectivity, irony, and agreement.
In previous versions of the Qlik Web Connectors, the MeaningCloud API was accessible through the Sentiment and Text Analytics Connector.
Supported offerings
- Qlik Sense Desktop
- Qlik Sense Enterprise on Windows
- QlikView
This connector must be installed separately.
Ways to access your data
To access your MeaningCloud data, you need to authenticate the connector with your MeaningCloud API key. Your MeaningCloud API key is the same as your license key.

Response | Value | Possible values |

Using the Sentiment table to get sentiment data for comments
The most effective way to use the MeaningCloud Connector is to pass data from a table into to the MeaningCloud Connector to produce a new table with the connector results. The example script below loads a table from an xlsx file, passes rows of data into the MeaningCloud connector, and produces a new table.
Example:
When you load data with a script like the one above, you should see one table called MeaningCloudConnector_Sentiment that has all of the MeaningCloud sentiment fields plus the two columns from the original data table. The original table that is used to pass data into the RegEx engine should not be available in Qlik Sense.
Working with the MeaningCloud API quota limits
The Qlik Web Connectors use the MeaningCloud API to extract data from MeaningCloud and load it into your Qlik Sense app. While reloading you MeaningCloud-based app, you might receive an error message that the connector has reached the MeaningCloud API rate limit and that all subsequent API calls will fail until the connector falls back under the throttling limit. If you receive this error message, then you have exceeded one of the API rate limits.
You receive an error message that you have reached the API rate limit
Reference - MeaningCloud developer documentation
You can refer to the MeaningCloud API documentation to learn more about the requirements and restriction imposed by the MeaningCloud API.
Troubleshooting
You receive an error message that you have reached the API rate limit
Possible cause
You have exceeded the API limits that are imposed on the Qlik Web Connectors by one of the MeaningCloud APIs.
Proposed action
To reduce the impact of reaching the API rate limits, develop your app with the following in mind:
- Extract only the data you need.
- Reload one MeaningCloud-based application at a time.
- Ensure that loops in your script that make API calls will not result in infinite loops.
