摘要： Described herein are various technologies pertaining to provision of query suggestions to a user independent of a query log. Key phrases are automatically identified in documents of a document corpus, and a forward index and inverted index are generated. The forward index indexes key phrases by documents, and the inverted index indexes documents by key phrases. A query is received from a user, and documents relevant to the query are retrieved. Key phrases in the retrieved documents are identified via the forward index, and a subset of the key phrases are selected as query suggestions by determining coverage of the key phrases as identified in the inverted index.

摘要： Semantic object characterization and its use in indexing and searching a database directory is presented. In general, a first binary hash code is generated to represent a first representation or view of a semantic object which when compared to a characterized version of a second representation or view of the same semantic object in the form of a second binary hash code, the first and second binary hash codes exhibit a degree of similarity indicative of the objects being the same object. In one implementation the semantic objects correspond to peoples' names and the first and second representations or views correspond to two different languages. Thus, a user can search a database of information in one language with a search query in another language.
摘要翻译： 介绍了语义对象表征及其在索引和搜索数据库目录中的用途。 通常，生成第一个二进制哈希码以表示语义对象的第一表示或视图，当与第二二进制散列码的形式的相同语义对象的第二表示或视图的特征版本进行比较时， 第一和第二二进制散列码表现出相似度的程度，表示对象是相同的对象。 在一个实现中，语义对象对应于人们的名字，并且第一和第二表示或视图对应于两种不同的语言。 因此，用户可以使用另一种语言的搜索查询来搜索具有一种语言的信息的数据库。

摘要： Browsing sequence phrase identification technique embodiments are presented that generally extract topically-related phrases from the pages visited by a user in a browsing session. The topically-related phrases can be used for a variety of purposes, including aiding a user in re-finding previously visited sites. This phrase identification task is performed by considering not just the pages of a user's browsing sequence individually, but also pages visited immediately before and immediately after each page. In this way, phrases found in a page can be analyzed in the context in which the page was viewed, rather than in isolation. The identified phrases are further filtered by picking those that appear on a pre-populated topic list, and then clustering to find the most informative ones.
摘要翻译： 提供了浏览序列短语识别技术实施例，其通常从浏览会话中由用户访问的页面提取局部相关的短语。 局部相关的短语可以用于各种目的，包括帮助用户重新查找以前访问过的网站。 这个短语识别任务是通过单独考虑用户的浏览序列的页面，而不仅仅考虑每个页面之前和之后立即访问的页面来执行的。 以这种方式，可以在页面被查看的上下文中而不是孤立地分析页面中发现的短语。 通过挑选出现在预先填充的主题列表中的那些进一步过滤所识别的短语，然后进行聚类以找到最有帮助的。

摘要： An approach is described for using a query expressed in a source language to retrieve information expressed in a target language. The approach uses a translation dictionary to convert terms in the query from the source language to appropriate terms in the target language. The approach determines viable transliterations for out-of-vocabulary (OOV) query terms by retrieving a body of information based on an in-vocabulary component of the query, and then mining the body of information to identify the viable transliterations for the OOV query terms. The approach then adds the viable transliterations to the translation dictionary. The retrieval, mining, and adding operations can be repeated one or more or times.

摘要： The keyword extraction technique described herein extracts keywords from Uniform Resource Locators (URLs) in web logs. The technique leverages the content and the structure of URLs to extract relevant keywords. First, a URL is divided into multiple components based on its structure. A set of keywords are extracted from each component of the URL independently with the help of a controlled vocabulary. Then a second set of keywords are generated by forming combinations of terms from different segments of the URL. Only those combinations which are present in the controlled vocabulary are retained as keywords. Finally, the keywords are scored with a function which took into account of a wide set of features.

摘要： Various technologies described herein pertain to suggesting context dependent keywords for advertising. A set of seed queries can be identified from a context, where the context is a source keyword, a search query, a category, or a landing page. Moreover, the set of seed queries can be inputted to a search engine. A predetermined number of web pages returned by the search engine upon executing the set of seed queries can be retrieved. Candidate keywords can be extracted from the web pages returned by the search engine. Further, keywords from the candidate keywords can be selected from the candidate keywords based on relevance scores of the candidate keywords.
