论文摘要
查询建议是指向搜索引擎用户建议相关和相关查询的任务,以帮助查询配方过程并以最少的努力加快信息检索。在搜索要求尚未充分了解并因此被搜索引擎广泛采用以指导用户的搜索活动的情况下,它非常有用。对于新闻网站,用户查询在其中固有的时间敏感性。当发生一些新事件时,与该事件有关的查询突然发生了,并且此类查询在一段时间内持续了一段时间,然后消失了该事件。除了在新闻网站上发射的搜索查询的这一时间方面外,它们还具有不同的质量,即,它们旨在获得与事件相关的信息的大多数时代。现有的生成查询建议的工作涉及分析查询日志,以建议与用户的搜索意图相关的查询。但是,对于新闻网站的情况,当与特定事件有关的信息突然爆发时,没有其他用户发出的搜索查询足以导致缺乏点击数据,因此给出了与某些旧事件甚至一些无关的建议有关的查询建议。在在线新闻的背景下,查询日志的另一个问题是,它们主要包含与流行事件有关的查询,因此未能捕获不流行的事件或事件,这些事件或事件被其他一些更具轰动性的事件所掩盖。我们提出了一种新颖的方法,使用新闻媒体发表的新闻文章的元数据生成以事件为中心的查询建议。我们将我们提出的框架与Google新闻,Bing News,Google Search和Bing搜索各种参数提供的现有最先进的建议机制进行了比较。
Query suggestion refers to the task of suggesting relevant and related queries to a search engine user to help in query formulation process and to expedite information retrieval with minimum amount of effort. It is highly useful in situations where the search requirements are not well understood and hence it has been widely adopted by search engines to guide users' search activity. For news websites, user queries have a time sensitive nature inherent in them. When some new event happens, there is a sudden burst in queries related to that event and such queries are sustained over a period of time before fading away with that event. In addition to this temporal aspect of search queries fired at news websites, they have an addition distinct quality, i.e., they are intended to get event related information majority of the times. Existing work on generating query suggestions involves analyzing query logs to suggest queries which are relevant and related to the search intent of the user. But in case of news websites, when there is a sudden burst in information related to a particular event, there are not enough search queries fired by other users which leads to lack of click data, and hence giving query suggestions related to some old event or even some irrelevant suggestions altogether. Another problem with query logs in the context of online news is that, they mostly contain queries related to popular events and hence fail to capture less popular events or events which got overshadowed by some other more sensational event. We propose a novel approach to generate event-centric query suggestions using metadata of news articles published by news media. We compared our proposed framework with existing state of the art query suggestion mechanisms provided by Google News, Bing News, Google Search and Bing Search on various parameters.
