AUTOMATIC INDEXING OF AUDIO-TEXTUAL DOCUMENTS BASED ON THEIR COMPREHENSION DIFFICULTY

摘要

The server (SD) automatically indexes audio-textual (DAT) and audio-visual digital documents in particular with a difficulty of comprehensibility index (IDC) of each specific document based on an index (IVE) resulting from a comparison of the elocution speed of the assessed document with at least a threshold. The difficulty of comprehensibility index may also depend on the numbers (nbFG) of predetermined grammatical structures included in each document as well as a vocabulary index (IVC) determined relative to predetermined glossaries. Each document is thus associated with a label assembling all the indices thereof to enable in particular students and teachers of a foreign language in front of their terminals (TE) to search for the documents in a base (SGBD) depending on their comprehension and their knowledge of the language of the documents.
