Considering Documents in Lifelog Information Retrieval

Abstract

Lifelogging is a research topic that is receiving increasing attention and although lifelog research has progressed in recent years, the concept of what represents a document in lifelog retrieval has not yet been sufficiently explored. Hence, the generation of multimodal lifelog documents is a fundamental concept that must be addressed. In this paper, I introduce my general perspective on generating documents in lifelogging and reflect on learnings from collecting multimodal lifelog data from a number of participants in a study on lifelog data organization. In addition, the main motivation behind document generation is proposed and the challenges faced while collecting data and generating documents are discussed in detail. Finally, a process for organizing the documents in lifelog data retrieval is proposed, which I intend to follow in my PhD research.
