The aim of the work package is to develop generalizable measurement methods to capture online-based innovations in the household sector. Different instruments of innovation research will be investigated and evaluated in this context. Previously identified interaction platforms in the three fields of action sustainable energy, sustainable mobility and sustainable urban development will be evaluated with the help of netnographic analyses to identify innovation activities. Netnography - derived from the words Internet and ethnography - investigates social behaviour on online platforms. The publicly available information of selected communities is collected, processed and analysed by means of web-scraping. Text mining, social network analysis and machine learning methods are used to identify innovations in the respective communities in a largely automated way. Whether this approach is transferable to other communities will be tested and evaluated. The suitability and meaningfulness of the developed indicators will be discussed and interlinked with the results of the qualitative investigations.
