To allow efficient and systematic retrieval of statements from Medline we have developed EBIMed, a service that combines document retrieval with co-occurrence-based analysis of Medline abstracts. Upon keyword query, EBIMed retrieves the abstracts from EMBL-EBI's installation of Medline and filters for sentences that contain biomedical terminology maintained in public bioinformatics resources. The extracted sentences and terminology are used to generate an overview table on proteins, Gene Ontology (GO) annotations, drugs and species used in the same biological context. All terms in retrieved abstracts and extracted sentences are linked to their entries in biomedical databases. We assessed the quality of the identification of terms and relations in the retrieved sentences. More than 90% of the protein names found indeed represented a protein. According to the analysis of four protein-protein pairs from the Wnt pathway we estimated that 37% of the statements containing such a pair mentioned a meaningful interaction and clarified the interaction of Dkk with LRP. We conclude that EBIMed improves access to information where proteins and drugs are involved in the same biological process, e.g. statements with GO annotations of proteins, protein-protein interactions and effects of drugs on proteins.

为了能够从Medline中高效且系统地检索语句,我们开发了EBIMed,这是一项将文献检索与基于共现的Medline摘要分析相结合的服务。在进行关键词查询时,EBIMed会从EMBL-EBI安装的Medline中检索摘要,并筛选出包含公共生物信息学资源中维护的生物医学术语的句子。提取的句子和术语用于生成一个关于在相同生物学背景下使用的蛋白质、基因本体(GO)注释、药物和物种的概述表。检索到的摘要和提取的句子中的所有术语都与其在生物医学数据库中的条目相关联。我们评估了检索到的句子中术语和关系识别的质量。发现超过90%的蛋白质名称确实代表一种蛋白质。根据对Wnt信号通路中四对蛋白质-蛋白质对的分析,我们估计包含这样一对的语句中有37%提到了有意义的相互作用,并阐明了Dkk与LRP的相互作用。我们得出结论,EBIMed改善了在蛋白质和药物参与相同生物学过程的情况下的信息获取,例如具有蛋白质的GO注释、蛋白质-蛋白质相互作用以及药物对蛋白质影响的语句。
