    "description": "<p><strong><a href=\"https://data.gesis.org/tweetscov19/\">TweetsCOV19</a></strong><strong> </strong>is a semantically annotated corpus of Tweets about the COVID-19 pandemic. It is a subset of <a href=\"https://data.gesis.org/tweetskb\">TweetsKB</a> and aims at capturing online discourse about various aspects of the pandemic and its societal impact. <strong>Metadata</strong> information about the tweets as well as extracted <strong>entities</strong>, <strong>sentiments</strong>, <strong>hashtags</strong>, <strong>user mentions</strong>, and <strong>resolved URLs </strong>are exposed in RDF using established RDF/S vocabularies*.</p>\n\n<p>We also provide a <em><strong>tab-separated values (tsv)</strong></em> version of the dataset. Each line contains features of a tweet instance. Features are separated by tab character (&quot;\\t&quot;). The following list indicate the feature indices:</p>\n\n<ol>\n\t<li>Tweet Id: Long.</li>\n\t<li>Username: String. Encrypted for privacy issues*.</li>\n\t<li>Timestamp: Format ( &quot;EEE MMM dd HH:mm:ss Z yyyy&quot; ).</li>\n\t<li>#Followers: Integer.</li>\n\t<li>#Friends: Integer.</li>\n\t<li>#Retweets: Integer.</li>\n\t<li>#Favorites: Integer.</li>\n\t<li>Entities: String. For each entity, we aggregated the original text, the annotated entity and the produced score from <a href=\"https://github.com/yahoo/FEL\">FEL</a> library. Each entity is separated from another entity by char &quot;;&quot;. Also, each entity is separated by char &quot;:&quot; in order to store &quot;original_text:annotated_entity:score;&quot;. If FEL did not find any entities, we have stored &quot;null;&quot;.</li>\n\t<li>Sentiment: String. <a href=\"http://sentistrength.wlv.ac.uk/\">SentiStrength</a> produces a score for positive (1 to 5) and negative (-1 to -5) sentiment. We splitted these two numbers by whitespace char &quot; &quot;. Positive sentiment was stored first and then negative sentiment (i.e. &quot;2 -1&quot;).</li>\n\t<li>Mentions: String. If the tweet contains mentions, we remove the char &quot;@&quot; and concatenate the mentions with whitespace char &quot; &quot;. If no mentions appear, we have stored &quot;null;&quot;.</li>\n\t<li>Hashtags: String. If the tweet contains hashtags, we remove the char &quot;#&quot; and concatenate the hashtags with whitespace char &quot; &quot;. If no hashtags appear, we have stored &quot;null;&quot;.</li>\n\t<li>URLs: String: If the tweet contains URLs, we concatenate the URLs using &quot;:-: &quot;. If no URLs appear, we have stored &quot;null;&quot;</li>\n</ol>\n\n<p>To extract the dataset from <a href=\"https://data.gesis.org/tweetskb\">TweetsKB</a>, we compiled a seed list of 268 COVID-19-related <a href=\"https://data.gesis.org/tweetscov19/keywords.txt\">keywords</a>.</p>\n\n<p><em>* For the sake of privacy, we anonymize&nbsp;user IDs&nbsp;and we do not provide the text of the tweets.</em></p>",
