What method can help determine if the word "Paris" refers to the city or the character in "The Iliad"?

Using linked entities extraction from the Language service is the most effective method for determining whether the word "Paris" refers to the city or the character in "The Iliad." Linked entity extraction identifies and disambiguates entities within text by linking them to known entities in a knowledge base.

In this case, when the term "Paris" appears in a context, linked entity extraction can help identify its specific reference by looking at the surrounding text and connecting it with established knowledge about the city of Paris versus the character from Greek mythology. This contextual understanding allows for accurate differentiation between multiple meanings of an entity.

The other methods provided do not effectively resolve ambiguity. Extracting key phrases may highlight "Paris," but it does not provide context to distinguish between the two meanings. Sentiment analysis focuses solely on the emotional tone of the text without addressing entity identification. Detecting the language of the text merely identifies what language is being used, rather than providing clarity on what the specific references in that language mean.
