Global News Index and Extracted Features Repository (v.1.3.0)

The Cline Center Global News Index is a searchable database of textual features extracted from millions of news stories, specifically designed to provide comprehensive coverage of events around the world. In addition to searching documents for keywords, users can query metadata and features such as named entities extracted using Natural Language Processing (NLP) methods and variables that measure sentiment and emotional valence.

Archer is a web application purpose-built by the Cline Center to enable researchers to access data from the Global News Index. Archer provides a user-friendly interface for querying the Global News Index (with the back-end indexing still handled by Solr). By default, queries are built using icons and drop-down menus. More technically-savvy users can use Lucene/Solr query syntax via a ‘raw query’ option. Archer allows users to save and iterate on their queries, and to visualize faceted query results, which can be helpful for users as they refine their queries.

克莱因中心全球新闻索引（Cline Center Global News Index）是一款可检索数据库，其数据源自数百万条新闻报道中提取的文本特征，专为全面覆盖全球各类事件而打造。除支持基于关键词的文档检索外，用户还可查询元数据，以及通过自然语言处理（Natural Language Processing）方法提取的命名实体、情感与情绪效价测量变量等特征。

Archer是克莱因中心专为研究人员访问全球新闻索引数据而开发的网页应用程序。该工具为用户检索全球新闻索引提供了友好的交互界面（其底层索引服务仍由Solr提供支持）。默认情况下，用户可通过图标与下拉菜单构建检索式；对于技术能力较强的使用者，还可通过「原始检索」选项使用Lucene/Solr检索语法。Archer支持用户保存检索式并进行迭代优化，同时可对分面检索结果进行可视化展示，这一功能有助于使用者进一步完善检索策略。
