[Objective] This paper reveals the change of uers’ interests in the crowdfunding projects and analyzes the dynamic evolution of their online comments on these projects. [Methods] First, we retrieved 497,936 online comments on 6,537 technology-related projects from Kickstarter as corpus. Then, with the help of LDA model, we analyzed the topic evolution of these comments. Finally, we obtained the dynamic evolution model of the topics with the help of cosine similarity. [Results] In the initial stage of financing, the comments were mainly on basic project information. Then, the comments focused on return of investments and product information. In the final stage, these comments were on the shipping issues. For successful projects, the topics developed from project description to waiting time for products and deliveries. For the failed projects, the comments gradually evolved into the possible relaunch and prospect of a new project. [Limitations] We did not distinguish the project categories, which need to be analyzed in the future. This paper only examined the reward based crowdfunding model, which also needs to be expanded. [Conclusions] This article analyzes reviews of online crowdfunding projects and expands the application of LDA in the field of crowdfunding, which provides practical suggestion for platforms, project sponsors and investors.
Hi there,I love what you are working on！ From the purpose to the design, there is so much potential. One of the stop motion shots I'm working on now （and for a while） involves a delay so a sheet of plastic can stabilize between frames. Wpuld it be it possible with RGKit Play to automate that delay? Or is there a way to synchronize but dissonate two motor actions?
The shelves that attach to the yellow arms and the yellow arms are definitely of interest. Basically gear that can be modified to length and attach to your motors to help move products. My concern is having motors that I end up having to build new gear for all the time for different uses.
Would it be possible to buy camera slide as an add-on
Content creator kit is no longer available. I’m unable to edit my reward.
Hi creators, is there any nee with regard shipment and customs specially for UK? It is very important to know what we are expecting in terms of time and cost. Thanks
I've been rewatching your videos on instagram and i really can't wait to get my RGKit Play ！！！ Good luck with the production guys.
