+Captions
+========
+
+
+The dev and test caption files follow the naming scheme:
+
+"img_<LANGUAGE>-en.tok.lc.filtered.(dev|test)"
+
+<LANGUAGE> is a two-letter code (de = German, fr = French, 
+ru = Russian).
+
+
+The format of the parallel image-caption pairs is:
+
+"imagename<tab>foreign_caption ||| english_caption"
+
+
+
+Dev and Test Images
+===================
+
+The images have to be downloaded manually. We provide a simple 
+bash-script for downloading, which makes use of the following 
+perl-script:
+
+https://commons.wikimedia.org/wiki/User:AzaToth/wikimgrab.pl
+
+Simply enter the "images" directory and call the script 
+"download_dev_test.sh" from there, e.g.:
+
+$ cd images
+$ source ./download_dev_test.sh
+
+Downloading the Full Corpus
+===========================
+
+We also provide a script for downloading the full corpus, i. e. 
+(monolingual and multilingual) image annotations and their
+associated images directly from Wikimedia commons. Note that 
+this may take a very long time (depending on your local bandwidth)
+and that we recommend distributing the task onto serveral machines.
+The script can be found in the "full_corpus" directory.
+
+We have compiled an index of 3.816.940 images on Wikimedia Commons.
+To download, for example, the first 20.000 images from the full 
+corpus (and their annotatins) do the following:
+
+$ cd full_corpus
+$ ./download_full_corpus.sh 0 20000 
+
+The images will be placed in sequentially numbered directories,
+one directory containg a maximum of 10.000 images. 
+
+The annotations will be written to files named XX.captions, where XX
+is a language identifier (en.cpations contains English captions, etc.)
+The files are tab-seperated in the following format:
+
+Corpus index <tab> Filename <tab> Annotated caption (including HTML "div"
+ with metadata)
+
+Please note that some images might have been deleted since the 
+index was created. They will be skipped.
