Abstract: In this paper, we propose a new approach to extracting question-context-answer triples from online discussion forums. More specifically, we propose a general framework based on Conditional Random Fields (CRFs) for context and answer detection, and also extend the basic framework to utilize contexts for answer detection and to better accommodate the features of forums.

Abstract: The present invention provides a new approach to extracting question-answer pairs from online forums. The system develops a classification-based technique to discover questions in forums using sequential patterns automatically extracted from both questions and non-question sentences in forums as features. Once the questions are discovered, the system discovers the answers. The invention includes a graph-based method is that it is complementary with supervised methods for knowledge extraction, and techniques for question answering.

Abstract: A question search system provides a collection of questions having words for use in evaluating the utility of the questions based on a language model. The question search system calculates n-gram probabilities for words within the questions of the collection. The n-gram probability of a word for a sequence of n−1 words indicates the probability of that word being next after that sequence in the collection of questions. The n-gram probabilities for the words of the collection represent the language model of the collection. The question search system calculates a language model utility score for each question within a collection that indicates the likelihood that a question is repeatedly asked by users. The question search system derives the language model utility score for a question from the n-gram probabilities of the words within that question.
Abstract translation: 问题搜索系统提供了具有用于评估基于语言模型的问题的效用的单词的问题的集合。 问题搜索系统计算收集问题内的单词的n-gram概率。 n-1个词序列的单词的n-gram概率表示该词在该问题集合中的该序列之后的概率。 集合词的n-gram概率表示集合的语言模型。 问题搜索系统计算集合中每个问题的语言模型效用得分，其指示用户重复询问问题的可能性。 问题搜索系统从该问题中的单词的n-gram概率得出问题的语言模型效用得分。

Abstract: Techniques for unsupervised management of a question and answer (QA) forum include labeling of answers for quality purposes, and identification of experts. In a QA thread, a ranking of answers may include an initial labeling of the longest answer in each thread as the best answer. Such a labeling provides an initial point of reference. Then, in an iterative manner answerers are ranked using the labeling. The ranking of answerers allows selection of experts and poor or inexpert answerers. A label update is performed using the experts (and perhaps inexpert answerers) as input. The label update may be used to train a model, which may describe quality of answers in one or more QA threads and an indication of expert and inexpert answerers. The iterative process may be ended upon convergence or upon a maximum number of iterations.
Abstract translation: 用于无人管理问答（QA）论坛的技术包括为质量目的标识答案，并确定专家。 在QA线程中，答案的排名可能包括每个线程中最长答案的初始标签作为最佳答案。 这样的标签提供了初步的参考点。 然后，以迭代的方式，使用标签对答复者进行排名。 回答者的排名允许选择专家和穷人或无经验的回答者。 使用专家（或许不太实际的回答者）作为输入进行标签更新。 标签更新可以用于训练模型，其可以描述一个或多个QA线程中的答案的质量以及专家和不熟练的答复者的指示。 迭代过程可以在收敛或最大迭代次数时结束。

Abstract: A method and system for presenting questions that are relevant to a queried question based on clusters of topics and clusters of focuses of the questions is provided. A question search system provides a collection of questions. Each question of the collection has an associated topic and focus. Upon receiving a queried question, the question search system identifies questions of the collection that may be relevant to the queried question and generates a score or ranking indicating relevance of the identified questions. The question search system clusters the identified questions into topic clusters of questions with similar topics. The question search system may also cluster the questions within each topic cluster into focus clusters of questions with similar focuses.

Abstract: Systems, methods, and computer-readable media for dynamically generating text associated with an advertisement are provided. Core text associated with an advertisement is received from an advertiser, as is at least one attribute relevant to the advertiser and/or a user. Based upon the received attribute(s), it is determined whether customization of the core text is desired. If customization is desired, the core text is modified and presented in association with the advertisement. If customization is not desired, the core text is presented in association with the advertisement. In one embodiment, target advertisement placement information may also be utilized to determine whether customization of the core text is desired.

Abstract: Described herein are techniques for extracting data records containing user-generated content from documents. The documents may be processed into document trees in which sub-trees represent the data records of the document. Domain constraints may be used to locate structured portions of the document tree. For example, anchor trees may be located as being sets of sibling sub-trees with similar tag paths that contain the domain constraints. The anchor trees may then be used to determine a record boundary (e.g., the start offset and length) of the data records. Finally, the data records may be extracted based on the anchor trees and the record boundaries.
