本文介绍了一个数据组织系统和真正的内容寻址存储器称为WEBSOM。它是一个两层自组织映射（SOM）架构，其中文档以描述其内容相似性的几何顺序映射为上层地图上的点。通过标准浏览工具，可以从文档的地图子集中选择最相似的文档。还可以提交关于所需文档的自由格式查询，从而WEBSOM定位最匹配的文档。本文所用的文档地图有10万多个地图结点，每个结点有315个输入，组织了100多万个文档，该系统已在通用计算机上用软件实现。
This paper describes a data organization system and genuine content-addressable memory called the WEBSOM. It is a two-layer self-organizing map (SOM) architecture where documents become mapped as points on the upper map, in a geometric order that describes the similarity of their contents. By standard browsing tools one can select from the map subsets of documents that are most similar mutually. It is also possible to submit free-form queries about the wanted documents whereby the WEBSOM locates the best-matching documents. The document map exemplified in this paper has over 100000 map nodes, with 315 inputs at each, and over 1000000 documents have been organized by it. The system has been implemented by software on a general-purpose computer.
