Targeted sentiment

Targeted sentiment analysis identifies the sentiments expressed about entities mentioned in the text. Amazon Comprehend assigns a sentiment rating to each mention of an entity, along with a confidence rating and other information. A sentiment rating can be neutral, positive, negative, or mixed.

In the Analyzed text panel, the console underlines each of analyzed entities. The color of the underlined text indicates the overall sentiment of the entity. If you hover your cursor over an entity, the console displays additional information in a pop-up window.

        The Targeted sentiment tab.

The Results table provides additional detail about each entity. If there are multiple mentions of the same entity, called a co-reference group, the table displays these mentions as a collapsible set of rows associated with the main entity.

In the following example, the entity is a person named Zhang Wei. The targeted sentiment analysis recognizes that each mention of your is a reference to the same person. The console displays these mentions as sub-entries of the main entity.
