Sentiment of keywords from annual reports of Slovak commercial bank

The dataset represents extracted keyword bigrams from documents published by commercial banks for the years 2007-2022. Lemmatization was applied to the extracted keywords and subsequently the sentiment (positive, negative, neutral) of these keywords was determined. The documents are divided into the categories of Pillar 3 Disclosure, which are documents that are required to be disclosed under Pillar 3. The second category is Pillar 3 Related, which are documents that are not directly required to be disclosed, but are related to mandatory disclosure. In the case of subcategories, we designated financial reports published at the level of a year and half a year with the summary category financial reports. The remaining subcategories match the name (type) of the document. The NAN value in the cells represents that the observed keyword did not appear in the observed document in that year.本数据集提取自2007至2022年间商业银行发布的文档中的关键词二元组（keyword bigrams）。首先对提取得到的关键词执行词形还原（lemmatization）处理，随后判定这些关键词的情感倾向，分为积极、消极、中性三类。文档分为两大类别：其一为第三支柱披露文档（Pillar 3 Disclosure），即依据巴塞尔协议第三支柱要求必须公开的官方文档；其二为第三支柱相关文档（Pillar 3 Related），即虽未被强制披露要求直接覆盖，但与强制披露内容存在关联的文档。关于子分类设置，我们将按年度及半年度发布的财务报告归入"财务报告"总分类；其余子分类均直接与文档的名称（类型）保持一致。表格单元格中的NAN（Not a Number）值代表对应年份的观测文档中未出现该关键词。
