中文简介:
英国医学杂志集团(BMJ Group)有一个广泛的和可变的内容集,包括一套医学杂志,在线学习材料,最佳实践指南,临床证据总结,一个医生2-doc在线论坛,和一个端口- folio系统。有一种新出现的需求是聚合这些内容类型,提供一个统一的标签和链接系统,以便相关的内容可以跨组检索。主要用例包括改进的搜索和浏览功能,以及(半)自动构建\专业门户,这些门户可能是医学性质的(如糖尿病)或非医学性质的(如NHS改革)。这对标准模式分析算法提出了挑战,部分原因是文档的高度技术性。以前的工作主要集中在针对医学本体(如MetaMap和UMLS)自动索引的工具的使用上,但是这种方法在计算资源、缺乏用户控制和仅对医学概念的限制方面存在缺陷。一种基于统计和语义方法的混合方法似乎有一些优点,可能是未来的发展方向。本报告将集中讨论采用这两种方法的初步工作,并讨论在此过程中出现的一些特定的技术问题。这是基于与Jonathon Peterson、Chris Wroe和Rob Challen的合作。
课程简介: The British Medical Journal Group (BMJ Group) has a wide and var- ied content set, including a suite of medical journals, online learning materials, best practice guidelines, clinical evidence summaries, a doc-2-doc online forum, and a port- folio system for doctors. There is an emerging need to aggregate accross these content types, providing a uni ed tagging and linking system, so that related content can eas- ily be retrieved across the group. The main use-cases include an improved search and browse capability, and the (semi-)automatic construction of \specialty portals", which may be medical in nature (e.g. diabetes) or non-medical (e.g. NHS reform). This pro- vides a challenge to standard Pattern Analysis algorithms, due in part to the highly technical nature of the documents. Prior work has mainly been focussed on the use of tools that automatically index against a medical ontology (such as MetaMap and UMLS), but this approach has drawbacks in terms of computational resources, lack of user control, and limitations to medical-only concepts. A hybrid approach based on statistiscal and semantic methods appears to have some merit, and may be the way forward. The presentation will focus on preliminary work taking the two approaches, and talk about some speci c technical issues that have arisen along the way. This is based on joint work with Jonathon Peterson, Chris Wroe, and Rob Challen.
