there are many fake projects on Kickstarter and Indiegogo, and they are usually hard to distinguish from real projects. This research is a pioneer study to try to find a way for helping humans to identify possible fake projects. We propose to extract keywords from the projects, the extracted keywords would give the user a better understanding of the project. We compared keyword extraction for crowdfunding projects by using RAKE, NLTK, LIAAD/YAKE, BERT, and Gensim models. We measured the keyword extraction performance of each model using the precision, recall, and F1 scores. According to the results, the NLTK model is the most efficient, with a precision of 54.40% and an F1 of 70.47%.
