Alternative search methods
- [Instructor] So far, we have covered text-based information retrieval, but voice, image, and sound can also be used to search for information. In these cases, the same semantic search approach applies but the input is a little different. For images, the image is parsed into vectors or pixels to search against the vectors in the database. There isn't as much semantics involved in that unless the description of the image is used to search for other images, in which case, the vectors are still used but now the subjects of the image are also needing to be recognized, and that's usually through pattern recognition tools. For voice, there is a lot more semantics involved in this type of search. The way humans verbally describe what they're looking for has a wider range of variables, not to mention the way that humans interpret what those things mean.
