LinkedTV Keyword Extraction Tool for Hypervideo

This online demo performs keyword extraction on German and Dutch text. The screen is split in two parts (for German and Dutch respectively). The form enables users to fill a text box with a document and indicate its name, and to submit the document for analysis. The document is then indexed, which may take a while depending on length. After indexing 20 top keywords are displayed on top of the screen. For the keyword extraction, the algorithm employs Part of Speech taggers for German and Dutch, also making feasible identification of key-phrases. Under the form, a list of already uploaded and indexed documents is shown. By clicking on the document name, the keywords extracted from the document along with its contents are displayed. Moreover, the user can update the text of an existing document and re-submit it for analysis. The uploaded documents can be deleted by clicking the cross symbol [X] placed after the document name.The preloaded documents have been built from content provided by LinkedTV partners' RBB (RBB Aktuell) and Sound & Vision (Tussen Kunst & Kitsch, AVRO).
