Locating A Snippet Using Location Data

Tisane provides structured location data to help pinpoint flagged text fragments.

The three key location attributes are:

• sentence_index : Zero-based index of the sentence containing the snippet.
• offset: Zero-based position of the first character in the snippet within the sentence.
• length : Number of characters in the snippet.

How To Get The String

1. Find the sentence text containing the snippet:
   • Navigate to the sentence_list node.
   • Select a node where index = sentence_index.
   • Alternatively, retrieve the sentence directly from the sentence list array.
2. Get the substring:
   • Use the offset and length values to get the substring from the sentence.

Why Relative Offsets Instead Of Absolute Positions?

We use sentence-based indexing instead of absolute offsets because many users need an actual sentence with the snippet for context.
