So in the text, proper nouns include "Lumion", and the filename like "Lumion-2024-4-2-Download.cache". So any part of the filename, numbers, hyphens, periods, are part of the proper noun and should not be altered. Therefore, when processing the text, I need to leave all the filenames, software names, proper nouns as they are.
Finally, I'll make sure that the output only includes the text without any markdown formatting, as per the user's request. The user specified to return text only, so I need to avoid any additional formatting or explanations. Just the transformed text with the word1 structure.
I have to make sure that the synonyms are accurate. Sometimes, context matters. For instance, "Guide" in the title is a title element, so synonyms should fit there. Also, words like "3D rendering" might need synonyms like "3D visualization", "3D graphics rendering", "3D digital imaging". Proper nouns like "Lumion" must stay as they are, even if they're part of the filename like "Lumion-2024-4-2-Download.cache". Lumion-2024-4-2-Download.cache
The text is about Lumion-2024-4-2-Download.cache. I need to make sure not to change "Lumion-2024-4-2-Download.cache" or "Lumion 2024-4-2" as those are proper nouns. Words like "cache," "associated," "process," etc., should be replaced with synonyms. Wait, does "every word" include every single word except proper nouns?
Let me proceed to process each sentence, ensuring that proper nouns are left as is and other words get three synonyms in spintax format. Also, remember that words in the filename like "Lumion-2024-4-2-Download.cache" should remain untouched, even if they contain common words. So in the text, proper nouns include "Lumion",
Also, check for any words that are already singular in context, like "update" in "a significant update". The synonyms should maintain the part of speech. "Update" can be addition.
I should also be cautious with words that have multiple meanings. For example, "cache" as a proper noun vs. a temporary storage file. Since the user told not to touch proper nouns, but "cache" in the filename is part of the proper noun, so it should stay. Wait, in the example, "cache" is part of the filename, but also used elsewhere. So "cache" in "cache file" would need synonyms. But "cache" in the filename is part of a proper noun, so it's left as-is. Hmm, tricky. The user probably wants each word in the original text (excluding proper nouns) to have three synonyms in spintax. So proper nouns stay, other words are replaced. Finally, I'll make sure that the output only
- "witnessed" → verbs: "observed", "encountered", "experienced".
