First, the input text is:
Need to be careful with words like "2018" when not in the title. The user might consider it a proper noun when part of the title but not when mentioned in the body text, but in the example, the user's own input has "2018" in the body text and it's being processed. So perhaps "2018" in the body text is not a proper noun, so it should be replaced. However, finding synonyms for a year is tricky. The user might expect a substitution, but perhaps the best approach is to replace "2018" with something like year, even if it's not a precise synonym.
So the process is:
But the user's example in the problem shows that in the first line, they wrote "I Am Angela -Evil Angel- -2018- —Split Scenes—" and left it as is. Then in the next line, words like "In 2018, a mysterious..." would have "In" replaced, "2018"—if part of the title, skipped. But in the text, "2018" is not part of the title, so it might be replaced. However, the user may have intended to include the year as part of the title, so it's unclear.
First, I need to identify the proper nouns in the text. Looking at the example: "As we continue to explore the mysteries of this title, one thing is certain: “I Am Angela -Evil Angel- -2018- —Split Scenes—” is a phrase that will linger in our minds, inspiring us to ponder the complexities of the human condition." I Am Angela -Evil Angel- -2018- ---Split Scenes---
So my approach would be:
The original text is:
But in the sentence "Split scenes imply...", the word "scenes" might not be part of the title anymore, but in this context, it's part of the title as a subtitle, so it's still a proper noun. Wait, the title is "—Split Scenes—", so "Split Scenes" is a subtitle within the title, so all parts of the title are considered proper and left as is. Therefore, in the text, whenever "Split Scenes" appears as part of the title, it remains unchanged. Otherwise, when used in another context, like "Split scenes imply...", those words are part of the text and should be replaced with synonyms.
