Development of an infrastructure for the implementation of a thematic access in the German Archives Portal (Archivportal-D) using exemplary archival holdings concerning the “Weimar Republic”

该项目第二阶段的目标是，在该项目第一阶段的示范专题访问“魏玛共和国”的基础上，优化以前开发的组成部分，确保它们的长期安全，并为后续用例处理它们。德国档案馆门户网站可以在国家级档案馆的档案字体和数字化材料中进行具体的、以研究为导向的调查。专题检索“魏玛共和国”以方便用户和通用的特点扩展了以前的研究选择。迄今为止，“魏玛共和国”(德国档案馆)和“君主制共和国-数字共和国”(巴登-符腾堡州)项目中数字化的档案字体一直是“魏玛共和国”的基础。随后将在第二个项目阶段提供更多档案数据。专题检索的基础是从参考词汇表系统中用不同实体类型的索引词丰富档案字体。因此，将这些术语与综合权威文件(GND)连接起来，加强了档案记录与语义网的整合。为了扩大专题访问范围内的研究可能性，将在第二项目阶段提供一个新的方面，即实体类型“人”。随后，通过这一首次完成的专题检索，将建立基础设施和工作流程，使研究机构和其他档案馆能够设计和维护自己的专题检索。为此，除了出版《魏玛共和国》参考词汇系统外，还将开发和提供不同实体类型的词汇系统和词汇模板。德国档案馆门户网站中的专题访问旨在成为一个完整的历史科学研究相关搜索工具，能够由档案馆和研究人员作为不同研究相关主题的协作信息中心建立和填充。作为新基础设施的一部分，为丰富档案类型而创建的索引工具将向科学界和公众开放，使用户能够作为网络2.0组件的一部分进行协作索引。在这方面，还将编写关于其他专题领域的一整套算法索引试验性工作。将进一步探讨通过算法进行自动标引的结果改进。

The goals of the second phase of this project are to optimize previous components developed on the basis of the exemplified thematic access “Weimarer Republik” within the first phase of the project, to secure them on a long term basis and to process them for following-up use cases. The German Archives´ Portal enables specific and research-orientated investigation within archival fonds and digitized material of archives at national level. The thematic access “Weimarer Republik” extends previous research options by user-friendly and generic features.Archival fonds digitized within the projects “Weimar – die erste deutsche Demokratie” (Bundesarchiv) and “Von der Monarchie zur Republik – Digitalisierung von Quellen des Landesarchivs zur Demokratiegeschichte“ (Landesarchiv Baden-Württemberg) have been the basis for “Weimarer Republik” so far. Data of further archives will follow during the second project phase.The thematic access is based on enriching archival fonds with index-terms of different entity types out of a referenced vocabulary system. Hereby, connecting the terms with the Integrated Authority File (GND) enhances the integration of archival records into semantic web.To expand research possibilities within the thematic access, a new facet, entity typ “person”, will be made available during the second project phase. Subsequently, by means of this first completed thematic access, infrastructure and workflows which make it possible for research institutions and other archives to devise and maintain own thematic accesses will be established.For this purpose, templates for vocabulary systems and vocabulary of the different entity types will be developed and made available in addition to the publication of the referenced vocabulary system of “Weimarer Republik”. The thematic accesses in the German Archives´ Portal intend to become an integral research-relevant searchtool-offer for historical sciences, able to be established and filled as collaborative information hubs for different research-relevant topics by both archives and researchers.As a part of the new infrastructure, the indexing tool which has been created to enrich archival fonds will be opened for scientific communities and the public to enable collaborative indexing by users as part of a web 2.0-component. In this context, the generalization of the experimental work package of algorithmic indexing will also be prepared with regard to other thematic areas. Further result improvements of automatic indexing by means of algorithms will be approached.
