Biomedical Text Mining (BioTM) is providing valuable approaches to the automated curation of scientific literature. However, most efforts have addressed the benchmarking of new algorithms rather than user operational needs. Bridging the gap between BioTM researchers and biologists’ needs is crucial to solve real-world problems and promote further research.We present @Note, a platform for BioTM that aims at the effective translation of the advances between three distinct classes of users: biologists, text miners and software developers. Its main functional contributions are the ability to process abstracts and full-texts; an information retrieval module enabling PubMed search and journal crawling; a pre-processing module with PDF-to-text conversion, tokenisation and stopword removal; a semantic annotation schema; a lexicon-based annotator; a user-friendly annotation view that allows to correct annotations and a Text Mining Module supporting dataset preparation and algorithm evaluation.@Note improves the interoperability, modularity and flexibility when integrating in-home and open-source third-party components. Its component-based architecture allows the rapid development of new applications, emphasizing the principles of transparency and simplicity of use. Although it is still on-going, it has already allowed the development of applications that are currently being used. 相似文献

目的 通过实验探讨EDTA在塑化根管再疏通治疗中是否能够溶解酚醛树脂.方法 分别制作聚合24 h、7 d、30 d、180 d的条形酚醛树脂实验模型,各取1 cm长20段,将一端0.5 cm长浸入EDTA凝胶,分别在1 min、5 min、10 min后取出,在显微镜下观察酚醛树脂表面形态.结果 不同聚合时间形成的酚醛树脂,经EDTA处理过的一端与未处理过的一端表面形态相比均无明显差异,且不随EDTA作用时间延长而改变.结论 在塑化根管再疏通治疗时所使用的EDTA并不能溶解酚醛树脂. 相似文献

针对中医药古籍文献进行语义标注,以《健康信息学—中医药学语言系统语义网络框架》中医药学语言系统的语义网络框架为标准,参考清代医籍的语料分类模式,结合中医古籍文献的特点,面向中医临床证治主题,选取与临床诊疗密切相关的“病—证—治—方—药”术语,探索性标注9类语料实体,提出中医药语料实体标注流程规范、总原则,并同时基于标注实践对在标注过程中产生的易混淆的实体进行进一步细化区分,以期为中医药文献语料实体标注研究提供参考,帮助研究人员快速、准确地进行知识检索与获取。 相似文献
