Abstract:
The goal of this paper is to introduce a set of techniques we call
semantic combination in order to efficiently fuse text and image
retrieval systems in the context of multimedia information access.
These techniques emerge from the observation that image and textual
queries are expressed at different semantic levels and that a
single image query is often ambiguous. Overall, the semantic combination
techniques overcome a conceptual barrier rather than a
technical one: these methods can be seen as a combination of late
fusion and image reranking. Albeit simple, this approach has not
been used yet. We assess the proposed techniques against late and
cross-media fusion using 4 different ImageCLEF datasets. Compared
to late fusion, performances significantly increase on two
datasets and remain similar on the two other ones.
