背景：Medline 等在线出版物和其他来源的快速增长提出了如何有效获取相关信息的问题。例如，对于一名实验科学家来说，持续监控相关出版物非常重要。对于临床医生来说，随时随地访问患者记录也很重要。尽管耗时，但这种搜索过程通常相似且简单。它可能涉及搜索引擎和可视化界面。不同的词语或组合反映了不同的研究主题。本研究的目的是通过将这些单词/术语记录在数据库和在线资源中，并使用这些信息进行自动搜索和检索，从而使这一繁琐的过程自动化。检索到的信息将通过安全的网络服务器随时随地提供。 结果：我们开发了这样一个数据库，存储搜索术语、期刊等，并实现了一个自动搜索医学主题索引源（例如 Medline 和其他在线源）的软件。返回的信息按原样存储在本地服务器上，并通过基于 Web 的界面可见。搜索是每天或以其他方式安排的，用户可以随时登录网站，无需输入任何文字。该系统有可能从非医学主题索引文献或临床信息系统等特权信息源中进行类似检索。因此，解决了检索信息的安全性、呈现和可视化等问题。无线接入等演示问题之一也进行了实验。一项用户调查显示，个性化在线搜索节省了时间并提高了相关性。手持设备也可用于访问存储的信息，但不太令人满意。结论：网络搜索软件或类似系统有潜力成为实验室科学家和临床医生满足日常信息需求的有效工具。
BACKGROUND: The rapid growth of online publications such as the Medline and other sources raises the questions how to get the relevant information efficiently. It is important, for a bench scientist, e.g., to monitor related publications constantly. It is also important, for a clinician, e.g., to access the patient records anywhere and anytime. Although time-consuming, this kind of searching procedure is usually similar and simple. Likely, it involves a search engine and a visualization interface. Different words or combination reflects different research topics. The objective of this study is to automate this tedious procedure by recording those words/terms in a database and online sources, and use the information for an automated search and retrieval. The retrieved information will be available anytime and anywhere through a secure web server.RESULTS: We developed such a database that stored searching terms, journals and et al., and implement a piece of software for searching the medical subject heading-indexed sources such as the Medline and other online sources automatically. The returned information were stored locally, as is, on a server and visible through a Web-based interface. The search was performed daily or otherwise scheduled and the users logon to the website anytime without typing any words. The system has potentials to retrieve similarly from non-medical subject heading-indexed literature or a privileged information source such as a clinical information system. The issues such as security, presentation and visualization of the retrieved information were thus addressed. One of the presentation issues such as wireless access was also experimented. A user survey showed that the personalized online searches saved time and increased and relevancy. Handheld devices could also be used to access the stored information but less satisfactory.CONCLUSION: The Web-searching software or similar system has potential to be an efficient tool for both bench scientists and clinicians for their daily information needs.
