Kiran Ramnath, Leda Sari, Mark Hasegawa-Johnson and Chang Yoo. "Worldly Wise (WoW) – Cross-Lingual Knowledge Fusion for Fact-based Visual Spoken-Question Answering", Annual Conference of the North American Chapter of the Association for Computational Li

Although Question-Answering has long been of research interest, its accessibility to users through a speech interface and its support to multiple languages have not been addressed in prior studies. Towards these ends, we present a new task and a synthetically-generated dataset to do Fact-based Visual Spoken-Question Answering (FVSQA). FVSQA is based on the FVQA dataset, which requires a system to retrieve an entity from Knowledge Graphs (KGs) to answer a question about an image. In FVSQA, the question is spoken rather than typed. Three sub-tasks are proposed: (1) speech-to-text based, (2) end-to-end, without speech-to-text as an intermediate component, and (3) cross-lingual, in which the question is spoken in a language different from that in which the KG is recorded. The end-to-end and cross-lingual tasks are the first to require world knowledge from a multi-relational KG as a differentiable layer in an end-to-end spoken language understanding task, hence the proposed reference implementation is called WorldlyWise (WoW). WoW is shown to perform endto-end cross-lingual FVSQA at same levels of accuracy across 3 languages – English, Hindi, and Turkish.
