This project focuses on enhancing existing document representations with representations of semantic content at a subdocument granularity; representing documents from multiple perspectives; and leveraging the attention and domain knowledge of end-users to improve document representations. This will lead to improvements in the retrievability of documents in future searches. The research will provide one of the first systematic studies of the potential added value of interpretation and labeling efforts contributed by a community of end users. In addition to evaluating the results of this particular approach to improving information retrieval, the work will contribute needed tools for evaluating incrementally-added indexing. An outcome of the research will be evaluation techniques that will be applicable to other research on incrementally-added indexing. The project builds a successful, interdisciplinary collaboration with the national, public, healthcare portal in Denmark, with strong participation from the government partner as well as physicians in Denmark who help to design the studies.

该项目的重点是增强现有的文档表示与语义内容表示在子文档粒度;表示文档从多个角度来看;并利用最终用户的注意力和领域知识，以改善文档表示。 这将导致在今后的检索中更好地检索文件。该研究将提供第一个系统研究的潜在附加值的解释和标签的努力，由最终用户的社区贡献。除了评估这种改进信息检索的特殊方法的结果外，这项工作还将为评估增量索引提供所需的工具。这项研究的成果将是评价技术，将适用于其他研究的增量增加索引。该项目与丹麦的国家公共医疗保健门户网站建立了成功的跨学科合作，政府合作伙伴以及丹麦的医生积极参与，帮助设计研究。
