In this paper we propose an approach to lightweight acquisition, sharing and annotation of experience-based corpora via mobile devices. Corpora acquisition is the crucial and often costly process in speech and language science and engineering. To address this problem, we have built a system for creating a location based corpora annotated with multimedia tags (e.g. text, speech, image) generated by end-users. We describe a relevant case study for the collection of mobile user life logs. We plan to make publicly available such tools and platforms to the research community for collaborative development and distributed experiential corpora collection.
