Questions tagged [extract]

Questions related to retrieving specific information from a (typically minimally structured) data source, such as a web site, media file, source code collection or compressed archive (in which case the desired information is one or more original, uncompressed files). When using this tag, please include additional tags to clarify which specific environment/language/scenario your question refers to.

Data extraction is a term with many different but related meanings, including:

  • Parsing files (such as HTML pages) or file metadata in order to obtain certain information. This often involves

  • Retrieving single frames from audio, video or image files

  • Breaking up functionality in a single source code unit (e.g. a function) into multiple units:

  • Retrieving the original files from a (optionally compressed) archive file, such as a .zip or .tar file.

and should be added as a synonym for this tag.
