Test collections have a long history of supporting repeatable
and comparable evaluation in Information Retrieval (IR).
However, thus far, no shared test collection exists for IR
systems that are designed to index and retrieve multimodal
lifelog data. In this paper we introduce the first test col-
lection for personal lifelog data. The requirements for such
a test collection are motivated, the process of creating the
test collection is described, along with an overview of the
test collection and finally suggestions are given for possible
applications of the test collection, which has been employed
for the NTCIR12-Lifelog task
