BACON. 4 is a production system that discovers empirical laws. The program represents information at varying levels of description, with higher levels summarizing the levels below them. BACON. 4 employs a small set of data-driven heuristics to detect regularities in numeric and nominal data.

BACON. 4 is a production system that discovers empirical laws. The program represents information at varying levels of description, with higher levels summarizing the levels below them. BACON. 4 employs a small set of data-driven heuristics to detect regularities in numeric and nominal data. These heuristics note constancies and trends, causing BACON. 4 to formulate hypotheses, to define theoretical terms, and to postulate intrinsic properties. The introduction of intrinsic properties plays an im portant role in BACON. 4's rediscovery of Ohm's law for electric circuits and Archime des' law of displacement. When augmented with a heuristic for noting common divisors, the system is able to replicate a number of early chemical discoveries, arriving at Proust's faw of definite proportions, Gay-Lussae's law of combining volumes, Cannizzaro's determination of the relative atomic weights, and Prout's hypothesis. The BACON. 4 heuristics, including the new technique for finding common divisors, appear to be general mechanisms applicable to discovery in diverse domains.

西蒙是著名的人工智能专家。他送给本刊发表的这篇文章介绍了人工智能研究新进展的一个重要方面,即用计算机发现科学定律。这里介绍的BACON.4是一种发现经验定律的生成子系统。该程序可以用不同的描述层次来表现信息,并在高一层次概括它们。它采用数据推导的试探程序来检测数字数据与名词性数据的规律性。这种程序注意到守恒量和倾向性,从而导致BACON.4提出假说、定义理论项、假设固有性质。这种试探程序还具有发现公约数的新技术,从而可以应用于不同的领域发现科学定律。

The amount of geophysical data available to scientists is becoming more overwhelming every day.However, those data exist in diverse formats. The data format problem is one of the most serious barriers faced by modem scientific data management and analysis. It hampers the data inter-operability and data sharing among data management and analysis systems. A solution, the standard format, has been tried but the problem has not been significantly diminished.One of the most exciting recent developments in geophysical data management is the creation and application of data description languages (DDL). Instead of constraining data to a small set of″standard″formats, the DDL approach confronts the diversity of data formats directly by describing data format explicitly using a data description mechanism. With this mechanism, format-independent data access and analysis tools can be developed to process data in any format describable by the mechanism, and datasets with their descriptions will be inter-operable between data management and analysis systems.This paper introduces the concept of data description language, discusses the benefit of DDL approach for solving the format problem, and details FREEFORM DDL with related data access system developed by NGDC and their applications in the geophysical data management.

科学家所能运用的科学数据每天都在增加,但这些数据都是以各种不同格式存在的。数据格式问题已成为当今数据管理和分析中的一大问题,它直接妨碍了数据的共享与通用性。其中一个解决办法是采用标准格式,但此方法经试验证明不能显著减轻格式问题。当前科学数据管理的最新进展之一,是数据描述语言的发展与采用。数据描述语言方法不限制数据于几种标准格式中,而是通过一种描述机制来直接描述所面临的各种格式。在这种机制下,我们可以发展格式独立的数据存取与分析系统来处理和分析任何可以被此机制所描述的格式的数据。同时,带有数据描述的数据可以在数据管理和分析系统中通用。本文介绍了数据描述语言的概念,讨论了数据描述语言方法在解决数据格式问题上的优越性,并着重介绍了由美国国家地球物理数据中心发展的数据描述语言FREEFORM及其相应的数据存取系统和它们在地球物理数据管理中的应用。
