摘要： An optimization-based framework is utilized to extract broad query aspects from query reformulations performed by users in historical user session logs. Objective functions are optimized to yield query aspects. At run-time, the best broad but unspecified query aspects relevant to any user query are presented along with the results of the run time query.

摘要： An improved system and method is provided for detecting a web page template. A web page template detector may be provided for performing page-level template detection on a web page. In general, the web page template classifier may be trained using automatically generated training data, and then the web page template classifier may be applied to web pages to identify web page templates. A web page template may be detected by classifying segments of a web page as template structures, by assigning classification scores to the segments of the web page classified as template structures, and then by smoothing the classification scores assigned to the segments of the web page. Generalized isotonic regression may be applied for smoothing scores associated with the nodes of a hierarchy by minimizing an optimization function using dynamic programming.

摘要： Methods, computer programs, and systems for generating a link title for a URL (Uniform Resource Locator) within a context webpage to be shown as a web result are provided. The method evaluates generation parameters for a plurality of sources for picking words from the link title. Further, the method generates candidates for the link title, and a likelihood is computed for each candidate. When computing the likelihood, the generation parameters, the context webpage and the words are considered. In addition, the method selects a candidate with the highest likelihood from all the computed likelihoods, and presents the URL with the selected candidate as the title.

摘要： According to techniques described herein, the best set of quicklinks is picked to maximize the benefits for a majority of the users of a search engine, since the “real estate” on a search results page is constrained and valuable. Quicklinks are navigational shortcuts that are displayed below the website homepage on a search results page. Using user browsing trails obtained from browser toolbars, and a simple probabilistic model, the quicklink selection program is formulated as a combinatorial optimization problem. Two techniques are proposed herein: a greedy technique and a tree-based technique. The tree-based technique finds an optimal solution, but may do so in a greater amount of time than the greedy technique takes to find a solution that is not guaranteed to be optimal. The tree-based technique may incorporate natural constraints on the set of chosen quicklinks.
摘要翻译：根据本文描述的技术，由于搜索结果页面上的“房地产”被限制和有价值，所以选择最佳的一组快速链接以使搜索引擎的大多数用户的利益最大化。快速链接是在搜索结果页面上显示在网站首页下方的导航快捷方式。使用从浏览器工具栏获得的用户浏览轨迹，以及简单的概率模型，将快速链接选择程序作为组合优化问题。本文提出了两种技术：贪心技术和基于树的技术。基于树的技术找到一个最佳解决方案，但可能会比贪婪技术花费更多的时间来找到不能保证是最佳的解决方案。基于树的技术可以在所选择的快速链接集合上引入自然约束。
