摘要： Exemplary embodiments allow performance of stream computations on real-time data streams using one or more map operations and/or one or more update operations. A map operation is a stream computation in which stream events in one or more real-time data streams are processed in a real-time manner to generate zero, one or more new stream events. An update operation is a stream computation in which stream events in one or more real-time data streams are processed in a real-time manner to create or update one or more static “slate” data structures that are stored in a durable manner.
摘要翻译：示例性实施例允许使用一个或多个地图操作和/或一个或多个更新操作来执行对实时数据流的流计算。地图操作是流计算，其中一个或多个实时数据流中的流事件以实时方式被处理以产生零个一个或多个新的流事件。更新操作是流计算，其中以实时方式处理一个或多个实时数据流中的流事件以创建或更新以耐用方式存储的一个或多个静态“平板”数据结构。

摘要： Systems and methods are disclosed herein for performing classification of documents or performing other tasks based on rules. A rule generator receives a request for a rule that will receive as an input a document and output an outcome such as a classification of the document, addition of the document to a whitelist or blacklist, or occurrence of some other outcome. The rules are applied to a document and the document and outcome of the rules are presented to a rater. A rating of the accuracy of the outcome is received from the rater and the rating is propagated to quality metrics of rules that contributed to the outcome. Rules with a quality metric above a threshold may be added to a production rule set. Rules with a quality metric below a threshold may be removed.
摘要翻译：本文公开了用于执行文档分类或基于规则执行其他任务的系统和方法。规则生成器接收到将作为输入文档接收的规则的请求，并输出结果，例如文档的分类，将文档添加到白名单或黑名单，或发生某种其他结果。规则适用于文件，规则的文件和结果将提交给评估者。从评分者获得结果的准确性评级，评级被传播到有助于结果的规则的质量度量。质量指标高于阈值的规则可能会添加到生产规则集中。质量指标低于阈值的规则可能会被删除。

摘要： Systems and methods are disclosed herein for ranking the quality of documents, such as documents shared or referenced in postings by users. For a first set of documents quality attributes that are indicative of quality or lack of quality are identified. Ratings of the quality of the first set of documents are received. Classifiers are associated with each document and the ratings and quality attributes for each attribute used to train class-specific models corresponding to the classifiers. Subsequently received documents are then classified and corresponding quality attributes are evaluated using the corresponding class-specific model in order to rank the quality of the document.

摘要： A method for merging two taxonomies is disclosed. Top levels of first and second taxonomies are merged. For the second taxonomy nodes are evaluated and selectively merged with nodes of the first taxonomy according to comparison of scores for these nodes with a threshold. The score for a node of the first taxonomy is a combination of one or more of a lineage quality score, Jaccard distance, string edit distance, and category depth score. After an iteration, mergings between nodes of the first and second taxonomies may be reversed if child nodes of the merged nodes were not likewise merged. Iterations may be repeated until no nodes are merged in an iteration.

摘要： Methods are disclosed for converting a directed graph to a taxonomy using guidelines from a user. An initial tree is output from a first pruning step in which subtree preferences (and other weights) are applied to preserve or remove paths from a node to one or more levels of descendent nodes. Subtree preferences (and infoboxes) may specify rules for automatically generating recommendations during application to nodes. In a second pruning step, the directed graph is again processed with additional weightings applied to edges in the graph in accordance with the recommendations. The recommendations may be human defined. Recommendations may specify a recommended ancestor for a particular node and may include a weighting to be applied to the recommendation itself, if there are multiple conflicting recommendations for the same node. Recommendations may also specify what standard weight to apply to the edge of the best parent.

摘要： Disclosed are methods for returning to a user an answer to the question “what is .” Concepts and classes to which the concepts belong are determined from a corpus, such as taxonomy. The concepts are mapped to categories according to the structure of the taxonomy. Homonyms for words are collected and scored according to likeliness of use. Concept vectors are assembled for the identified concepts based on articles in the corpus and social media usage. Words are evaluated for generic-ness and a generic score is associated therewith. In responding to a query, the generic-ness of the terms of the query is evaluated and additional context solicited if the terms are generic. Candidate homonym concepts for a string in the query are selected according to context vectors for the homonym concepts. One or more homonym concepts are selected and the one or more categories corresponding to these concepts are returned.
