How Does This Sentence Counter Work?
Our sentence counter uses advanced NLP to understand the text pattern, and its context, and break it into tokens (words). Then, it uses Sentence Boundary Detection (SBD) to split text based on full stop, exclamation & question marks, etc.
However, it skips abbreviations (like Mr., Dr., etc.) numbers, URLs, currency, and email addresses. Lastly, this tool uses its large datasets training model to understand all writing styles and provides exact sentence count, taking great care of SBDs.
