NIF（神经科学信息框架）项目的首要目标是成为神经科学的一站式商店。本文提供了一个技术概述如何设计系统。第一版NIF系统的技术目标是开发一个信息系统，神经科学家可以使用它通过简单的关键字查询从各种信息源中找到相关信息。虽然用户只提供关键词来检索信息，但NIF系统的设计是将它们视为概念，其含义由系统解释。因此，对术语的搜索应该找到包含该术语的同义词的记录。该系统的目标是从网页、出版物、数据库、建立在数据库基础上的网站、XML文件和任何其他可能发布此类信息的方式中查找信息。我们设计了一个系统来实现这个功能。在该系统中的一个中心元素是一个本体称为NIFSTD（NIF标准），通过合并一些已知的和新开发的本体构建。我们的本体管理模块OntoQuest使用NIFSTD对数据源进行基于本体的搜索。NIF体系结构目前提供了三种不同的机制来搜索异构数据源，包括关系数据库、网站、XML文档和出版物全文。NIF系统的1.0版目前正在进行beta测试，可通过http://nif.nih.gov访问。
The overarching goal of the NIF (Neuroscience Information Framework) project is to be a one-stop-shop for Neuroscience. This paper provides a technical overview of how the system is designed. The technical goal of the first version of the NIF system was to develop an information system that a neuroscientist can use to locate relevant information from a wide variety of information sources by simple keyword queries. Although the user would provide only keywords to retrieve information, the NIF system is designed to treat them as concepts whose meanings are interpreted by the system. Thus, a search for term should find a record containing synonyms of the term. The system is targeted to find information from web pages, publications, databases, web sites built upon databases, XML documents and any other modality in which such information may be published. We have designed a system to achieve this functionality. A central element in the system is an ontology called NIFSTD (for NIF Standard) constructed by amalgamating a number of known and newly developed ontologies. NIFSTD is used by our ontology management module, called OntoQuest to perform ontology-based search over data sources. The NIF architecture currently provides three different mechanisms for searching heterogeneous data sources including relational databases, web sites, XML documents and full text of publications. Version 1.0 of the NIF system is currently in beta test and may be accessed through http://nif.nih.gov.
