Fair media should present reliable and objective information. In practice there is an observable positive or negative bias concerning named entities (e.g. politicians) mentioned in the on-line news headlines.<br> Our dataset consists of 3819 human-labelled political news headlines coming from several major on-line media outlets in English and Polish.</p> <p>Each record contains a news headline, a named entity mentioned in the headline and a human annotated label (one of &ldquo;positive&rdquo;, &ldquo;neutral&rdquo;, &ldquo;negative&rdquo;&nbsp;). Our SEN dataset package consists of 2 parts: SEN-en (English headlines that split into SEN-en-R and SEN-en-AMT), and SEN-pl (Polish headlines). Each headline-entity pair was annotated via&nbsp;team of volunteer researchers (the whole SEN-pl dataset and a subset of 1271 English records: the SEN-en-R subset, &ldquo;R&rdquo; for &ldquo;researchers&rdquo;) or via the Amazon Mechanical Turk service (a subset of 1360 English records: the SEN-en-AMT subset).</p> <p>During analysis of annotation outlying&nbsp;annotations and removed . Separate version of dataset without outliers is marked by &quot;noutliers&quot; in data file name.</p> <p>Details&nbsp;of&nbsp;the process of preparing the dataset and presenting its analysis are presented in the&nbsp;paper.<br> &nbsp;</p> <p>In case of any questions, please contact one of the authors.
