In this paper we present a first version of the LifeSeeker interactive
lifelog retrieval engine that is under development at Dublin City
University. This retrieval engine has been designed as a platform
onto which future lifelog annotation and retrieval engines will be
built. The first implementation of LifeSeeker has been designed for
the LSC’19 comparative benchmarking challenge and it takes the
form of a faceted search and browsing interface with the addition
of query expansion to help solve the lexical-gap between novice
users and the concept annotation tools employed for annotating
the collection.
