    "description": "<p>The HWRT database of handwritten symbols contains on-line data of handwritten symbols such as all alphanumeric characters, arrows, greek characters and mathematical symbols like the integral symbol.</p>\n\n<p>The database can be downloaded in form of bzip2-compressed tar files. Each tar file contains:</p>\n\n<ul>\n\t<li>symbols.csv: A CSV file with the rows symbol_id, latex, training_samples, test_samples. The symbol id is an integer, the row latex contains the latex code of the symbol, the rows training_samples and test_samples contain integers with the number of labeled data.</li>\n\t<li>train-data.csv: A CSV file with the rows symbol_id, user_id, user_agent and data.</li>\n\t<li>test-data.csv: A CSV file with the rows symbol_id, user_id, user_agent and data.</li>\n</ul>\n\n<p>All CSV files use \";\" as delimiter and \"'\" as quotechar. The data is given in YAML format as a list of lists of dictinaries. Each dictionary has the keys \"x\", \"y\" and \"time\". (x,y) are coordinates and time is the UNIX time.</p>\n\n<p>\u00a0</p>\n\n<p>About 90% of the data was made available by Daniel Kirsch via github.com/kirel/detexify-data. Thank you very much, Daniel!</p>",
