REMINDER: Historical Media Analysis on Migration 2003-2017 (OA edition)

Full edition for public use. The principle of free movement allows citizens of the European Union (EU) to cross EU borders to live, work, or travel in other EU member states. It is one of the “four freedoms”, and a fundamental principle of the EU. However, since the so-called “refugee movements” in 2015, free movement within Europe and migration into the EU are fiercely debated topics, particularly in the media. This dataset allows users to comprehensively map migration media coverage in seven EU countries over the past fifteen years. Data can be used to compare the salience and sentiment of coverage pertaining to the two different concepts of migration (i.e. general migration vs. intra-European mobility), as well as investigate the salience and corresponding sentiment of specific, migration-related media frames. The dataset was collected within the Horizon 2020 Project REMINDER using automated content analysis and consists of annotations of migration-related news articles published between January 1, 2003 and December 31, 2017 in Spain, UK, Germany, Sweden, Poland, Hungary, and Romania. Due to data restrictions, the dataset is divided into two subdatasets (Corpus A and Corbus B) that differ with relation to the included countries, outlets and the time span. Corpus A includes media coverage from six countries and 17 media outlets from 2003 to 2017, while Corpus B covers seven countries and 39 media outlets from 2013 to 2017.

本数据集为面向公众使用的完整版。欧盟（EU）的自由流动原则允许欧盟成员国公民跨越欧盟边境，前往其他欧盟成员国生活、工作或旅行，该原则是欧盟"四大自由"之一，亦是欧盟的核心基本原则。然而，自2015年所谓的"难民潮"事件以来，欧洲内部自由流动与欧盟外来移民问题成为舆论热议的焦点，在媒体领域尤为突出。本数据集可帮助用户全面绘制过去15年间7个欧盟国家的移民相关媒体报道图景，可用于对比两类移民相关概念（即广义移民与欧盟内部流动）的报道显著性与情感倾向，同时可探究特定移民相关媒体框架的报道显著性及其对应情感倾向。本数据集由欧盟地平线2020（Horizon 2020）研究计划下的REMINDER项目依托自动化内容分析技术采集完成，涵盖2003年1月1日至2017年12月31日期间西班牙、英国、德国、瑞典、波兰、匈牙利、罗马尼亚7国发布的移民相关新闻文章标注数据。受数据限制，本数据集分为两个子数据集，即语料库A（Corpus A）与语料库B（Corpus B），二者在覆盖国家、媒体机构及时间跨度上均存在差异：语料库A涵盖2003年至2017年间6个国家的17家媒体机构的报道数据，语料库B则覆盖2013年至2017年间7个国家的39家媒体机构的报道数据。
