Twitter Mapping Example

Twitter Mapping Example

Your organization, Hypomarket Corporation, needs to review all the tweets that mention your product HypoBasket with a positive attitude since the time you released the product in February 2012.
Create a mapping that identifies tweets that contain the word HypoBasket and writes those records to a table.
You can use the following objects in a Twitter mapping:
Twitter input
The mapping source is a Twitter data object that contains the resource Search.
Create a physical data object and add the data object to the mapping. Add the Search resource to the physical data object. Modify the query parameter with the following query:
QUERY=HypoBasket:)&since:2012-02-01
Sorter transformation
Optionally, sort the data based on the timestamp.
Add a Sorter transformation to the mapping. Specify the timestamp as the sort key with direction as ascending.
Mapping output
Add a relational data object to the mapping as a target.
After you run the mapping, Data Integration Service writes the extracted tweets to the target table. You can use text analytics and sentiment analysis tools to analyze the tweets.
