Publish or be damned? The fate of abstracts presented at the International Continence Society Meeting 2003

AIMS: This study examined the presented abstracts from the International Continence Society (ICS) Meeting, 2003. It analyzed the rate and timing of full publication, the factors predicting successful publication, the consistency of reporting between presented abstracts and published abstracts, and the barriers to publication. MATERIALS AND METHODS: The abstracts presented at ICS 2003, were categorized according to topic, nationality, and a range of methodological factors. Using keywords and author names, PubMed was searched for published papers corresponding to the work presented. For abstracts that had been published, the original abstract was compared with the abstract accompanying the full-text paper. For abstracts that could not be identified in PubMed, the main authors were surveyed with an email questionnaire, asking about reasons for non-publication. RESULTS: Of 130 presented abstracts, 77 (61.6%) had been published in full by February 2006. Authors from the US were significantly more likely to have had their work published. Uniquely among topics, "Clinical Pharmacology" abstracts were significantly more likely to have been published. Fourteen (18.2%) abstracts were classified as having major inconsistencies between the presented abstract and the abstract accompanying the full-text paper. Inconsistencies between presented and published abstracts were significantly associated with delay in publication on Kaplan-Meier analysis. Most unpublished abstracts had never been submitted for publication. CONCLUSIONS: The high publication rate reflects well on the scientific quality of the ICS meeting. All authors should be encouraged to publish their work after presentation. Caution is advised when referencing or generalizing from abstracts that have not been published in full.

基于领域数据库的科技期刊知识服务模式的探索与实践

【目的】 探讨科技期刊与相关领域数据库相结合的模式,为读者提供多资源、多层次的知识服务内容,为科技期刊探索知识服务的范围及方法提供参考和借鉴。【方法】 以整合生物学期刊网的3种中文学术期刊——《植物生态学报》《植物学报》《生物多样性》为研究对象,分析科技期刊基于学科领域专业数据库提供知识服务的可能性及意义,提出设计思路及整体架构,探索科技期刊与不同类型数据库的合作方式。【结果】 经过实践,所提出的知识服务模式已在3种中文期刊中全面应用,促进了知识传播,提升了期刊影响力。【结论】 基于领域数据库的科技期刊知识服务模式实现了多资源、多层次的“网络化”“立体化”出版,可为读者提供广泛而精准的专业知识服务。此模式可供其他学科领域科技期刊、期刊群、期刊全文数据库参考应用。     

基于中医药领域本体的信息检索模型研究

针对传统基于关键词匹配的中医药信息检索存在查全率和查准率低下的缺陷,将本体与潜在语义索引相结合,提出一种基于中医药领域本体的语义信息检索模型.该模型基于本体概念扩展树构建相应的查询扩展方法和语义向量空间模型,将用户查询和文档集映射到同一潜在语义空间,通过计算查询向量与文档之间的相似度返回检索结果.着重阐述了该模型的体系结构、实现过程和关键技术,并对其实用性进行论证.     

Using CISMeF MeSH "Encapsulated" terminology and a categorization algorithm for health resources

INTRODUCTION: CISMeF is a Quality Controlled Health Gateway using a terminology based on the Medical Subject Headings (MeSH) thesaurus that displays medical specialties (metaterms) and the relationships existing between them and MeSH terms. Objective: The need to classify the resources within the catalogue has led us to combine this type of semantic information with domain expert knowledge for health resources categorization purposes. Material and METHODS: A two-step categorization process consisting of mapping resource keywords to CISMeF metaterms and ranking metaterms by decreasing coverage in the resource has been developed. We evaluate this algorithm on a random set of 123 resources extracted from the CISMeF catalogue. Our gold standard for this evaluation is the manual classification provided by a domain expert, viz. a librarian of the team. RESULTS: The CISMeF algorithm shows 81% precision and 93% recall, and 62% of the resources were assigned a "fully relevant" or "fairly relevant" categorization according to strict standards. DISCUSSION: A thorough analysis of the results has enabled us to find gaps in the knowledge modeling of the CISMeF terminology. The necessary adjustments having been made, the algorithm is currently used in CISMeF for resource categorization.

知识元标引在中医古籍临证文献标引中的应用

中医古籍临证文献数量庞大,内容复杂,包括理、法、方、药等方面,如要获取和利用古籍中的临证知识,必须建立一套相对严谨的知识网络和语义关系网络。知识元标引是对古籍文献内容进行合理解构,揭示古籍中蕴含的知识和信息,成为发现知识的重要方法和途径。
