LITERATURE CONSTRUCTION AND EXTENSION

我们已经开始研究如何使用大量的语料库 关于主题的文献，以最有效地扩展 在这样的数据库中按相关材料存储文件。这是 从根本上不同于如何找到 与单个文档密切相关的文档。一张是给的 更多的数据。到目前为止，我们已经使用了LOGDS方法 取得了一些成功。我们希望尝试的另一种方法 未来是基于以下方面的邻里数据的汇集 数据库中的单个文档。这样的汇集可能会给一个 对可能有用的材料有很好的想法。这 整个可拓问题也可以从 初步建构了一种文学的观点。 我们也希望看到这个问题，并建议采取措施 一种方法的成功取决于必须有多少文件 被检查以找到给定数量的相关 文件。

We have begun work on how to use a large corpus of literature on a topic to most efficiently extend the set of documents in such a database by related material. This is fundamentally different than the problem of how to find a document closely related to a single document. One is given much more data. Thus far we have used a logodds approach with some success. Another approach which we hope to try in the future is the pooling of neighborhood data based on single documents in the database. Such pooling may give a good idea of what is likely to be useful material. This whole problem of extension can also be studied from the point of view of the initial construction of a literature. We hope to look at this problem also and propose to measure the success of a method by the number documents that must be examined in order to find a given number of relevant documents.
