信息检索的数据库方法:语言模型和区域模型之间的显著关系

A database approach to information retrieval: The remarkable relationship between language models and region models

Djoerd Hiemstra, Vojkan Mihajlovic

摘要:

在这份报告中,我们统一了两种截然不同的信息检索方法:区域模型和语言模型。区域模型被开发用于结构化文档检索。它们提供了定义良好的行为和简单的查询语言,使应用程序开发人员能够快速开发应用程序。语言模型对于推理搜索结果的排名和开发新的排名方法特别有用。统一模型允许应用程序开发人员将复杂的语言建模方法定义为文本数据库上的逻辑查询。我们展示了一个显着的区域查询和语言模型,他们代表了各种各样的应用程序之间的一对一的关系:简单的ad-hoc搜索,跨语言检索,视频检索和Web搜索。

英文摘要:

In this report, we unify two quite distinct approaches to information retrieval: region models and language models. Region models were developed for structured document retrieval. They provide a well-defined behaviour as well as a simple query language that allows application developers to rapidly develop applications. Language models are particularly useful to reason about the ranking of search results, and for developing new ranking approaches. The unified model allows application developers to define complex language modeling approaches as logical queries on a textual database. We show a remarkable one-to-one relationship between region queries and the language models they represent for a wide variety of applications: simple ad-hoc search, cross-language retrieval, video retrieval, and web search.
