搜索引擎已成为 web 内容的主要入口点, 而 web 的大部分 "可见" 包含它们作为最高检索结果呈现的内容。因此, 如果第一个结果是整个结果集的代表性样本, 那将是可取的。本文对 "克隆" 或 "移民" 等有争议的查询的搜索引擎结果中包含的观点进行了初步研究。为此, 我们从网页中提取情感元数据, 并比较多个查询的搜索引擎结果。此外, 我们还将最高结果中表达的意见与其他检索结果中表达的意见进行比较, 以从意见的角度检查排名靠前的页面是否是所有结果的良好样本。在初步实证分析中, 我们比较了来自3个商业搜索引擎的14个有争议的查询的多达50个结果, 以研究情感、主题和排名之间的关系。

| 课程简介: |
Search Engines have become the main entry point to Web content, and a large part of the \visible" Web consists in what is presented by them as top retrieved results. Therefore, it would be desirable if the fi rst few results were a representative sample of the entire result set. This paper provides a preliminary study about opinions contained in search engine results for controversial queries such as "cloning" or "immigration". To this end, we extract sentiment metadata from web pages, and compare search engine results for several queries. Furthermore, we compare opinions expressed in the top results to those in other retrieved results to examine whether the top-ranked pages are a good sample of all results from an opinion perspective. In a preliminary empirical analysis, we compare up to 50 results from 3 commercial search engines on 14 controversial queries to study the relation between sentiments, topics, and rankings.
