Contents of files<br>
-----------------

* scaleconcept16.concepts.tar.gz

  -&gt; scaleconcept16.concepts.txt

     List of 251 concepts for the 2016 challenge. File format:<br>
     wordnet-offset \t category-word.pos.## \t list,of,synonyms,separated,by,commas \t defintiion

  -&gt; scaleconcept16.concepts_hierarchy.txt

     The hierarchy structure of the 'general level' categories. File format:<br>
     *category \t *parent-category \t definition.<br>
     For example, *mammal is the child of *animal. '#' represents the root node.

  -&gt; scaleconcept16.concepts_to_parents.txt

     List of 'general level' category parent(s) for each 251 concept. A concept may<br>
     have multiple parents (separated by commas). File format:<br>
     category \t *parent1,*parent2

 

* Features/scaleconcept16_ImgID.txt_Mod.tar.gz

  IDs of the images in the dataset.

<br>
* Features/scaleconcept16_TextID.txt_Mod.tar.gz

  IDs of the webpages in the dataset.

<br>
* Features/scaleconcept16_ImgToTextID.tar.gz

  IDs of images that appear on corresponding web pages

<br>
* Features/scaleconcept16.teaser.TrainTestSplit.*.tar.gz

  For Teasers 1 and 2: IDs of images and webpages, split into approximately<br>
  300K for training and exactly 200K for testing.<br>
  The 200K test data cannot be explored during training for both teaser tasks.

 

* Features/Textual/scaleconcept16_data_textual.scofeat.tar.gz    

  The processed text extracted from the webpages near where the images<br>
  appeared. Each line corresponds to one image, having the same order<br>
  as the data_iids.txt list. The lines start with the image ID,<br>
  followed by the number of extracted unique words and the<br>
  corresponding word-score pairs. The scores were derived taking into<br>
  account 1) the term frequency (TF), 2) the document object model<br>
  (DOM) attributes, and 3) the word distance to the image. The scores<br>
  are all integers and for each image the sum of scores is always<br>
  &lt;=100000 (i.e. it is normalized).

<br>
* Features/Textual/scaleconcept16_data_textual.webpages.tar.gz

  Contains all of the webpages which referenced the images in the<br>
  dataset set after being converted to valid xml. In total there are<br>
  525766 files, since each image can appear in more than one page, and<br>
  there can be several versions of same page which differ by the<br>
  method of conversion to xml. To avoid having too many files in a<br>
  single directory (which is an issue for some types of partitions),<br>
  the files are found in subdirectories named using the first two<br>
  characters of the RID, thus the paths of the files after extraction<br>
  are of the form:

    ./scaleconcept16_data_textual.webpages/{RID:0:2}/{RID}.{CONVM}.xml.gz

 

* Features/Visual/scaleconcept16_images.zip

  Contains thumbnails (maximum 640 pixels of either width or height)<br>
  of the images in jpeg format. To avoid having too many files in a<br>
  single directory (which is an issue for some types of partitions),<br>
  the files are found in subdirectories named using the first two<br>
  characters of the image ID, thus the paths of the files after extraction<br>
  are of the form:

    ./scaleconcepts16_images/{IID:0:2}/{IID}.jpg

<br>
* Features/Visual/scaleconcept16_*.{s|d}feat.gz

  The visual features in a simple ASCII text format either in sparse<br>
  (*.sfeat.gz files) or dense (*.dfeat.gz files). The first<br>
  line of the file indicates the number of vectors (N) and the<br>
  dimensionality (DIMS). Then each line corresponds to one vector.<br>
  For the dense features each line has exactly DIMS values separated<br>
  by spaces, i.e., the format is:

    N DIMS<br>
    Val(1,1) Val(1,2) ... Val(1,DIMS)<br>
    Val(2,1) Val(1,2) ... Val(2,DIMS)<br>
    ...<br>
    Val(N,1) Val(N,2) ... Val(N,DIMS)

  For the sparse features, each line starts with the number of non-zero<br>
  elements and is followed by dimension-value pairs, being the first<br>
  dimension 0, i.e., the format is:

    N DIMS<br>
    nz1 Dim(1,1) Val(1,1) ... Dim(1,nz1) Val(1,nz1)<br>
    nz2 Dim(2,1) Val(2,1) ... Dim(2,nz2) Val(2,nz2)<br>
    ...<br>
    nzN Dim(N,1) Val(N,1) ... Dim(N,nzN) Val(N,nzN)

  The order of the features is the same as in the list data_iids.txt.

  The procedure to extract the SIFT based features in this<br>
  subdirectory was conducted as follows. Using the ImageMagick<br>
  software, the images were first rescaled to having a maximum of 240<br>
  pixels, of both width and height, while preserving the original<br>
  aspect ratio, employing the command:

    convert {IMGIN}.jpg -resize '240&gt;x240&gt;' {IMGOUT}.jpg

  Then the SIFT features where extracted using the ColorDescriptor<br>
  software from Koen van de Sande<br>
  (http://koen.me/research/colordescriptors). As configuration we<br>
  used, 'densesampling' detector with default parameters, and a hard<br>
  assignment codebook using a spatial pyramid as<br>
  'pyramid-1x1-2x2'. The number in the file name indicates the size of<br>
  the codebook. All of the vectors of the spatial pyramid are given in<br>
  the same line, thus keeping only the first 1/5th of the dimensions<br>
  would be like not using the spatial pyramid. The codebook was<br>
  generated using 1.25 million randomly selected features and the<br>
  k-means algorithm. The GIST features were extracted using the<br>
  LabelMe Toolbox. The images where first resized to 256x256 ignoring<br>
  original aspect ratio, using 5 scales, 6 orientations and 4<br>
  blocks. The other features colorhist and getlf, are both color<br>
  histogram based extracted using our own implementation.

<br>
* Features/Visual/scaleconcept16_data_visual_vgg16-relu7.dfeat.gz

  Contains the 4096 dimensional activations of the relu7 layer of Oxford<br>
  VGG's 16-layer CNN model, extracted using the Berkeley Caffe library.<br>
  More details can be found at https://github.com/BVLC/caffe/wiki/Model-Zoo.

 

* DevData/MainSubTasks/scaleconcept16.dev.viusal.bbox.*.tar.gz

  Development set ground truth localised annotations for sub task 1.

  The format for the development set of annotated bounding boxes of<br>
  the concepts is

  &lt;image_ID&gt; &lt;seq&gt; &lt;Concept&gt;  &lt;confidence&gt; &lt;xmin&gt; &lt;ymin&gt; &lt;xmax&gt; &lt;ymax&gt;

  The development set contains 1,979 images. The bounding boxes may enclose<br>
  single instances (a single tree) or grouped instances (e.g. group of trees),<br>
  depending on the context. The annotations are not exhaustive: the emphasis<br>
  is on concepts that are interesting enough to be described in the image,<br>
  although background objects are also optionally annotated by our annotators<br>
  in many cases. Also note that a person might not be annotated if the<br>
  annotator could not decide whether the person is a man/woman/boy/girl.

<br>
* DevData/MainSubTasks/scaleconcept16.dev.textdesc.*.tar.gz

  Development set ground truth textual description annotations of images for<br>
  Subtask 2

  The format is:

  &lt;image_ID&gt; \t &lt;text_description_seq&gt; \t &lt;textual_description&gt;

  The development set contains 2,000 images with 5 to 51 textual descriptions<br>
  per image (mean: 9.492, median: 8). Please note that the sentences contain a<br>
  mix of both American and British English spelling variants (e.g. color vs<br>
  colour) -- we have decided to retain this variation in the annotations to<br>
  reflect the challenge of real-world English spelling variants. Basic<br>
  spell-correction has been performed on the textual descriptions, but we cannot<br>
  guarantee that they are completely free from spelling or grammatical error.

<br>
* DevData/MainSubTasks/scaleconcept16.subtask3.dev.input_bbox.*.gz

  Input bounding boxes for Subtask 3. This is a selected subset of 500 development<br>
  images from scaleconcept16.dev.visual.bbox above (please refer to above for file format).

<br>
* DevData/MainSubTasks/scaleconcept16.subtask3.dev.textdesc.*.gz

  Annotated textual descriptions for 500 development images, to be used to evaluate<br>
  the content selection ability of the text generation system in the clean track of<br>
  SubTask 3. The format is the same as the original scaleconcept16.dev.textdesc<br>
  file, except that we further annotated textual terms with their corresponding<br>
  input bounding boxes, for example [[[dogs|0,4]]] in a textual description refers<br>
  to the two instances of dogs with the bounding box id 0 and 4 in<br>
  scaleconcept16.subtask3.dev.input_bbox.

  Note that not all descriptions from the original scaleconcept16.dev.textdesc are<br>
  used in this version, and as such the sequence numbers of the descriptions may not<br>
  necessarily be contiguous as we retained the sequence numbers from the original<br>
  file for consistency.

 

* DevData/TeaserTasks/scaleconcept16.teaser_dev_id.*.tar.gz

  -&gt; scaleconcept16.teaser_dev.ImgID.txt<br>
     IDs of 3339 images for the development set of both teaser tasks. Note that 2 images<br>
     are near-duplicates and will thus not be used in this dataset. We have left them<br>
     intact to avoid having participants re-download the visual features.

  -&gt; scaleconcept16.teaser_dev.TextID.txt<br>
     IDs of 3337 webpage documents for the development set of both teaser tasks.
