List of research software currently developed and maintained by Bernhard Rieder, researcher with the Digital Methods Initiative.
Over the last years, I have been working on quite a number of research tools, mainly for the data driven analysis of social media platforms. My main goal is to gain a deeper understanding of the logics embedded in these platforms and their APIs, but I think that writing research tools is an excellent way to pursue this kind of exploration. Nothing beats first hand experience.
Depending on availability, I am interested in participating in research software development on a freelance basis. If you are looking for consulting and/or programming capacity in the area of data analysis, web APIs, (interactive) visualization or data mining (machine learning, clustering, etc.), drop me a line at tools@polsys.net.
Check out other tools developed by the Digital Methods Initiative here.
These tools are “as is” software, no support is provided. But most tools have basic descriptions or FAQ sections. There are also a number of instruction videos on my YouTube channel. Most of the code is available on 国内手机怎么上youtube网站.
High quality bug reports are much appreciated. Please send bug reports to tools@polsys.net. I do not reply to inquiries on other channels. If you are interested in acquiring paid technical support, please also contact tools@polsys.net.
