Working Paper

As digital information is increasingly becoming multimodal, the days of single-language text-only retrieval are numbered. Take as an example Wikipedia where a single topic may be covered in several languages and include non-textual media such as image, audio, and video. Moreover, non-textual media may be annotated with text in several languages in a variety of metadata fields such as object caption, description, comment, and filename. Current search engines usually focus on limited numbers of modalities at a time, e.g. English text queries on English text or maybe on textual annotations of other media as well, not making use of all information available. Final rankings are usually results of fusion of individual modalities, a task which is tricky at best especially when noisy modalities are involved.
