| This example application analyzes and stores customer feedback cards. Specifically, | ||
| it fulfills the need of a fictitious hotel in New York City. The hotel receives feedback | ||
| from guests in various languages in the form of physical comment cards. That feedback | ||
| is uploaded into the app through a web client. | ||
|
|
||
| After an image of a comment card is uploaded, the following steps occur: | ||
| </para> | ||
| <itemizedlist> | ||
| <listitem> | ||
| <para>Text is extracted from the image using &TEXTRACT;.</para> | ||
| </listitem> | ||
| <listitem> | ||
| <para>&CMP; determines the sentiment of the extracted text and its language.</para> | ||
| </listitem> | ||
| <listitem> | ||
| <para>The extracted text is translated to English using &TSL;.</para> | ||
| </listitem> | ||
| <listitem> | ||
| <para>&POL; synthesizes an audio file from the extracted text.</para> | ||
| </listitem> | ||
| </itemizedlist> | ||
| <para> The full app can be deployed with the &CDK;. For source code and deployment | ||
