Each line in the file<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; corresponds to an image, starting with the IID and is followed<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; by one or more URLs.</p>\n\n<p>&nbsp; -&gt; train{|2}_rimgsrc.txt : The URLs of the images as referenced in each<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; of the webpages. Each line of the file is of the form: IID RID<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; URL1 [URL2 ...]. This information is necessary to locate the<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; images within the webpages and it can also be useful as a<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; textual feature.</p>\n\n<p>* webupv14_{devel|test}_lists.zip</p>\n\n<p>&nbsp; -&gt; {devel|test}_conceptlists.txt : Lists per image of concepts for<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; annotation. Each line starts with an image ID and is followed by the<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; list of concepts in alphabetical order. Each ID may appear more than<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; once. In total there are 1940 image annotation lists for the<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; development set and 7291 image annotation lists for the test set. These<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; correspond to 1000 and 4122 unique images (IDs) for the development and<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; test sets, respectively.</p>\n\n<p>&nbsp; -&gt; {devel|test}_allconcepts.txt : Complete list of concepts for the<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; development/test set.</p>\n\n<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The concepts are defined by one or more WordNet synsets, which is<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; intended to make it possible to easily obtain more information about<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the concepts, e.g. synonyms. In the concept list, the first column<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (which is the name of the concept) indicates the word to search in<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; WordNet, the second column the synset type (either noun or adjective),<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the third column is the sense number and the fourth column is the<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; WordNet offset (although this cannot be trusted since it changes<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; between WordNet versions). For most of the concepts there is a fifth<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; column which is a Wikipedia article related to the concept.</p>\n\n<p>&nbsp; -&gt; {devel|test}_groundtruth.txt : Ground truth concepts for the development<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; and test sets.</p>\n\n<p>&nbsp; -&gt; {devel|test}_*urls.txt : The original URLs from where the images (iurls)<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; and the webpages (rurls) were downloaded. Each line in the file<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; corresponds to an image, starting with the IID and is followed by one<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; or more URLs.</p>\n\n<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Note: These are included only to acknowledge the source of the<br>\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; data, not be used as input to the annotation systems.</p>\n\n<p><br>\n* webupv14_baseline.zip</p>\n\n<p>&nbsp; An archive that includes code for computing the evaluation measures<br>\n&nbsp; for two baseline techniques. See the included README.txt for<br>\n&nbsp; details.</p>\n\n<p><br>\n* feats_textual/webupv14_train{|2}_textual_pages.zip</p>\n\n<p>&nbsp; Contains all of the webpages which referenced the images in the<br>\n&nbsp; training set after being converted to valid xml. In total there are<br>\n&nbsp; 262588 files, since each image can appear in more than one page, and<br>\n&nbsp; there can be several versions of same page which differ by the<br>\n&nbsp; method of conversion to xml. To avoid having too many files in a<br>\n&nbsp; single directory (which is an issue for some types of partitions),<br>\n&nbsp; the files are found in subdirectories named using the first two<br>\n&nbsp; characters of the RID, thus the paths of the files after extraction<br>\n&nbsp; are of the form:</p>\n\n<p>&nbsp;&nbsp;&nbsp; ./WEBUPV/pages/{RID:0:2}/{RID}.{CONVM}.xml.gz</p>\n\n<p>&nbsp; To be able to locate the training images withing the webpages, the<br>\n&nbsp; URLs of the images as referenced are provided in the file<br>\n&nbsp; train_rimgsrc.txt.</p>\n\n<p>* feats_textual/webupv14_train{|2}_textual.scofeat.gz</p>\n\n<p>&nbsp; The processed text extracted from the webpages near where the images<br>\n&nbsp; appeared. Each line corresponds to one image, having the same order<br>\n&nbsp; as the train_iids.txt list. The lines start with the image ID,<br>\n&nbsp; followed by the number of extracted unique words and the<br>\n&nbsp; corresponding word-score pairs. The scores were derived taking into<br>\n&nbsp; account 1) the term frequency (TF), 2) the document object model<br>\n&nbsp; (DOM) attributes, and 3) the word distance to the image. The scores<br>\n&nbsp; are all integers and for each image the sum of scores is always<br>\n&nbsp; &lt;=100000 (i.e. it is normalized).</p>\n\n<p><br>\n* feats_textual/webupv14_train{|2}_textual.keywords.gz</p>\n\n<p>&nbsp; The words used to find the images when querying image search<br>\n&nbsp; engines. Each line corresponds to an image (in the same order as in<br>\n&nbsp; train_iids.txt). The lines are composed of triplets:</p>\n\n<p>&nbsp;&nbsp;&nbsp; [keyword] [rank] [search_engine]</p>\n\n<p>&nbsp; where [keyword] is the word used to find the image, [rank] is the<br>\n&nbsp; position given to the image in the query, and [search_engine] is a<br>\n&nbsp; single character indicating in which search engine it was found<br>\n&nbsp; (&#39;g&#39;:google, &#39;b&#39;:bing, &#39;y&#39;:yahoo).</p>\n\n<p><br>\n* feats_visual/webupv14_*_images.zip</p>\n\n<p>&nbsp; Contains thumbnails (maximum 640 pixels of either width or height)<br>\n&nbsp; of the images in jpeg format. To avoid having too many files in a<br>\n&nbsp; single directory (which is an issue for some types of partitions),<br>\n&nbsp; the files are found in subdirectories named using the first two<br>\n&nbsp; characters of the IID, thus the paths of the files after extraction<br>\n&nbsp; are of the form:</p>\n\n<p>&nbsp;&nbsp;&nbsp; ./WEBUPV/images/{IID:0:2}/{IID}.jpg</p>\n\n<p>* feats_visual/webupv14_*.feat.gz</p>\n\n<p>&nbsp; The visual features in a simple ASCII text sparse format. The first<br>\n&nbsp; line of the file indicates the number of vectors (N) and the<br>\n&nbsp; dimensionality (DIMS). Then each line corresponds to one vector,<br>\n&nbsp; starting with the number of non-zero elements and followed by pairs<br>\n&nbsp; of dimension-value, being the first dimension 0. In summary the file<br>\n&nbsp; format is:</p>\n\n<p>&nbsp;&nbsp;&nbsp; N DIMS<br>\n&nbsp;&nbsp;&nbsp; nz1 Dim(1,1) Val(1,1) ... Dim(1,nz1) Val(1,nz1)<br>\n&nbsp;&nbsp;&nbsp; nz2 Dim(2,1) Val(2,1) ... Dim(2,nz2) Val(2,nz2)<br>\n&nbsp;&nbsp;&nbsp; ...<br>\n&nbsp;&nbsp;&nbsp; nzN Dim(N,1) Val(N,1) ... Dim(N,nzN) Val(N,nzN)</p>\n\n<p>&nbsp; The order of the features is the same as in the lists<br>\n&nbsp; devel_conceptlists.txt, test_conceptlists.txt and train_iids.txt.</p>\n\n<p>&nbsp; The procedure to extract the SIFT based features in this<br>\n&nbsp; subdirectory was conducted as follows. Using the ImageMagick<br>\n&nbsp; software, the images were first rescaled to having a maximum of 240<br>\n&nbsp; pixels, of both width and height, while preserving the original<br>\n&nbsp; aspect ratio, employing the command:</p>\n\n<p>&nbsp;&nbsp;&nbsp; convert {IMGIN}.jpg -resize &#39;240&gt;x240&gt;&#39; {IMGOUT}.jpg</p>\n\n<p>&nbsp; Then the SIFT features where extracted using the ColorDescriptor<br>\n&nbsp; software from Koen van de Sande<br>\n&nbsp; (http://koen.me/research/colordescriptors). As configuration we<br>\n&nbsp; used, &#39;densesampling&#39; detector with default parameters, and a hard<br>\n&nbsp; assignment codebook using a spatial pyramid as<br>\n&nbsp; &#39;pyramid-1x1-2x2&#39;. The number in the file name indicates the size of<br>\n&nbsp; the codebook. All of the vectors of the spatial pyramid are given in<br>\n&nbsp; the same line, thus keeping only the first 1/5th of the dimensions<br>\n&nbsp; would be like not using the spatial pyramid. The codebook was<br>\n&nbsp; generated using 1.25 million randomly selected features and the<br>\n&nbsp; k-means algorithm. The GIST features were extracted using the<br>\n&nbsp; LabelMe Toolbox. The images where first resized to 256x256 ignoring<br>\n&nbsp; original aspect ratio, using 5 scales, 6 orientations and 4<br>\n&nbsp; blocks. The other features colorhist and getlf, are both color<br>\n&nbsp; histogram based extracted using our own implementation.</p>\n\n<p>&nbsp;</p>",
