Manually read tweets and label their relevance to a topic (3)

**This requires a native English speaker.** The task is to read through a spreadsheet of 950 tweets. You will be asked to mark whether each tweet is about a particular topic (in this case, artificial intelligence) , as well as whether your classification is obvious or uncertain. The primary skills required are: native fluency in English, the ability to use an Excel spreadsheet, basic familiarity with the topic (expertise not required, just the level of familiarity an average American would be expected to have), and patience and detail-orientedness. I expect this to take about 6 hours of time, and need it done ASAP (ideally within the next 24 hours.) It is tedious, but easy. I will pay $95 for good work turned around quickly. Detailed instructions and the spreadsheet are attached. I am looking for multiple people to independently repeat this task and will post multiple similar projects. Feel free to bid on multiple since I can only assign each project to one person -- but I will not assign you more than one of the same topic.
