When you submit text, it is analyzed by Google’s advanced natural language processing technology. This analysis determines the salience of various topics, entities, and keywords within your text. Salience is assessed based on several factors including the frequency of entities, their placement within the document (whether they appear at the beginning, middle, or end), the frequency with which sentences start with these entities, and other relevant factors.
All of this is meticulously processed by Google’s API to provide a comprehensive understanding of the importance and relevance of each entity in your text.
