摘要

时间是与大量搜索相关的重要维度，例如博客和新闻档案。到目前为止，搜索此类集合的研究主要集中在为查询定位拓扑相似的文档。遗憾的是，单独的主题相似性并不总是足以用于文档排名。在本文中，我们观察到，对于我们称之为时间敏感查询的一类重要查询，文档在新闻档案中的发布时间很重要，应结合主题相似性来推导最终文档排名。早期的工作重点是改进针对最近文档的新近度查询的检索。我们提出了一个更通用的框架来处理时间敏感的查询，我们自动识别可能对查询感兴趣的重要时间间隔。然后，我们构建了将时间方面无缝集成到整体排名机制中的评分技术。我们使用各种新闻文章数据集进行广泛的实验评估，包括TREC数据以及使用Amazon Mechanical Turk分析的真实网络数据。我们研究了几种用于检测新闻档案中查询的重要时间间隔以及将这些信息合并到检索过程中的技术。我们表明，与最先进的检索技术相比，我们的技术非常强大，可显着提高时间敏感查询的结果质量。

Answering General Time-Sensitive Queries
Wisam Dakka, Luis Gravano, and Panagiotis G. Ipeirotis, Member, IEEE

Abstract
Time is an important dimension of relevance for a large number of searches, such as over blogs and news archives. So far,research on searching over such collections has largely focused on locating topically similar documents for a query. Unfortunately,topic similarity alone is not always sufficient for document ranking. In this paper, we observe that, for an important class of queries that we call time-sensitive queries, the publication time of the documents in a news archive is important and should be considered in conjunction with the topic similarity to derive the final document ranking. Earlier work has focused on improving retrieval for "recency"queries that target recent documents. We propose a more general framework for handling time-sensitive queries and we automatically identify the important time intervals that are likely to be of interest for a query. Then, we build scoring techniques that seamlessly integrate the temporal aspect into the overall ranking mechanism. We present an extensive experimental evaluation using a variety of news article data sets, including TREC data as well as real web data analyzed using the Amazon Mechanical Turk. We examine several techniques for detecting the important time intervals for a query over a news archive and for incorporating this information in the retrieval process. We show that our techniques are robust and significantly improve result quality for time-sensitive queriescompared to state-of-the-art retrieval techniques.

推荐答案

你的家庭作业只有标题而没有细节。甚至没有关于给你这个任务时所教的内容的任何背景。 ：doh：



一般情况下，

您需要在页面上设置一个计时器，该计时器会重置每个问题或跟踪总计时间。设计您的应用程序，以便有一系列问题答案，您可以逐个显示给用户回答。跟踪用户回答特定考试所花费的时间。让时间限制的最终目标是限制用户在给定的时间范围内回答问题。



继续，将需求分成几个小步骤继续前进。如果您遇到困难，请分享您的工作并在需要帮助的地方发布具体问题。



试试！

Your homework assignment just has a title and no details. Not even any context around what was taught when this assignment was given to you. :doh:

In general,
You need to have a timer on the page which resets with every question or keeps a track of total time. Design your application such that there are series of question answers and you can show them one by one to user to answer. Track the time taken by the user to answer a particular exam. Your ultimate goal of having it time bound is to restrict user to answer questions within a given time frame.

Go ahead, divide the requirement into various small steps and move on. If you get stuck, share your effort and post specific issues where you want help on.
