FAQ
What types of data can you label?
I can label both text and image datasets. For text, I handle classification, sentiment, and intent labeling. For images, I can perform tagging, categorization, and basic bounding box annotations.
Do you use any automated labeling tools?
No, all labeling is done manually and carefully verified to ensure accuracy and consistency. Automation can introduce bias or mistakes, so I only use tools to speed up workflow (not to replace human review).
What file formats do you accept?
I can work with Excel (.xlsx), CSV, JSON, or TXT files. For images, I can handle JPG, PNG, or ZIP archives with labeled data references.
Can you follow my custom labeling guide or taxonomy?
Absolutely. You can provide your own labeling instructions, or I can create a structured guide for you based on sample data and your project goals.
Can you clean and organize the data before labeling?
Yes, data cleaning is included in the Standard and Premium packages. I’ll remove duplicates, fix formatting errors, and make sure your dataset is consistent before labeling.
How do I send you large datasets or image folders?
You can share your files using Google Drive, Dropbox, OneDrive, or WeTransfer links. Just make sure the files are accessible or set to “Anyone with the link.”
What if I’m not satisfied with the results?
Every order includes revisions. I’ll adjust the labeling or formatting until it meets your expectations, within the agreed project scope.
Can you handle recurring or long-term labeling projects?
Definitely! I regularly collaborate on ongoing AI data projects. You can contact me for a custom offer based on your volume and labeling frequency.
How fast can you deliver?
Small projects (Basic) are usually ready in 1 day. Larger datasets depend on complexity, but I always deliver on time and I can provide progress updates if needed.
