ILCM - A Virtual Research Infrastructure for Large-Scale Qualitative Data.

The iLCM project pursues the development of an integrated research environment for the analysis of structured and unstructured data in a Software as a Service architecture (SaaS). The research environment addresses requirements for the quantitative evaluation of large amounts of qualitative data with text mining methods as well as requirements for the reproducibility of data-driven research designs in the social sciences. For this, the iLCM research environment comprises two central components. First, the Leipzig Corpus Miner (LCM), a decentralized SaaS application for the analysis of large amounts of news texts developed in a previous Digital Humanities project. Second, the text mining tools implemented in the LCM are extended by an Open Research Computing (ORC) environment for executable script documents, so-called notebooks. This novel integration allows to combine generic, high-performance methods to process large amounts of unstructured text data and with individual program scripts to address specific research requirements in computational social science and digital humanities.
