A Survey on Multimodal Information Retrieval Approach

There has been more content with various types needed by users. It comes from specific websites or databases. It causes a need to access the content through a retrieval system that can produce content that meets the demand. The existing searching applications still provide services aimed at only one particular modality, such as text, audio, or video. Therefore, research aimed at developing multimodal searching systems is still a significant opportunity in this field. In this paper, we review the multimodal information retrieval systems that have proposed in the previous research. And they discussed the components and mechanisms of the multimodal retrieval used by them. In this way, it will be clear on how they apply their approach to problem-solving on multimodality content searching. At the end of the discussion, there are some ideas or issues related to the problem.
