摘要： An information retrieval system uses phrases to index, retrieve, organize and describe documents. Phrases are extracted from the document collection. Documents are the indexed according to their included phrases, using phrase posting lists. The phrase posting lists are stored in an cluster of index servers. The phrase posting lists can be tiered into groups, and sharded into partitions. Phrases in a query are identified based on possible phrasifications. A query schedule based on the phrases is created from the phrases, and then optimized to reduce query processing and communication costs. The execution of the query schedule is managed to further reduce or eliminate query processing operations at various ones of the index servers.

摘要： A system detects hidden elements in a document that includes a group of elements. The system may identify each of the elements in the document and create a structural representation of the document. The structural representation may provide an interconnection of the group of elements in the document. The system may also determine whether one or more elements of the group of elements are hidden based at least in part on locations or other attributes or properties of the one or more elements in the structural representation.
摘要翻译：系统检测包含一组元素的文档中的隐藏元素。系统可以识别文档中的每个元素并创建文档的结构表示。结构表示可以提供文档中的该组元素的互连。该系统还可以至少部分地基于结构表示中的一个或多个元素的位置或其他属性或属性来确定该组元素中的一个或多个元素是否被隐藏。

摘要： Described herein are systems and methods for bidirectional matching. In overview, various embodiments provide software, hardware and methodologies underlying a bidirectional matching approach that implements a multi-level importance weighting procedure. Generally speaking, potential relationships between parties are scored on the basis of criterion matches. In some embodiments, a value is assigned to each criterion match based on a function of predefined factor, which is optionally experientially defined, and a further factor, which is defined based on individual preferences.

摘要： A server provides the user's desired data without the server knowing the contents or keywords of data by using a method of searching the desired data without decrypting the encrypted data, such that the privacy for the important data of the user can be secured. Also, the present invention shortens the operation time when searching the encrypted data, such that it can prevent the degradation in efficiency due to excess operation involved in the previous existing methods based on the pairing operation.
摘要翻译：服务器通过使用搜索所需数据而不解密加密数据的方法来提供用户期望的数据，而无需服务器知道数据的内容或关键字，从而可以确保用户的重要数据的隐私。此外，本发明缩短了搜索加密数据时的操作时间，从而可以基于配对操作来防止由于先前存在的方法中涉及的超量操作而导致的效率的降低。

摘要： Technology is described for associating semantic meaning with data elements. The system can include a messaging module configured to receive a message having data elements. A storage module can store the data elements from the message in a structured format. A message dictionary can be configured to identify a type of the message received and to lexically identify data elements of the message using the message dictionary and the type of message. In addition, a taxonomy module can be configured to provide a semantic meaning for the data elements of the lexically identified portions of the message. Further, a data definition tag repository can store data definition tags and link the message dictionary, the taxonomy, and storage location of the data elements in the storage module. The data definition tags can enable the semantic meaning of data elements to be queried.

摘要： Methods, systems, and apparatus, including computer program products are provided for ranking distinct book content items based on implicit links to other distinct book content items. The implicit links are defined based on the identification of matching features in the distinct book content items. In some implementations, the matching features are uncommon phrases in textual content of the distinct book content items. Edges representing implicit links are generated between distinct nodes representing distinct book content items in a weighted graph. Search results for distinct book content items can be ordered based on the edges connected to the distinct nodes in the weighted graph that represent the distinct book content items.

摘要： A domain-specific sentiment classifier that can be used to score the polarity and magnitude of sentiment expressed by domain-specific documents is created. A domain-independent sentiment lexicon is established and a classifier uses the lexicon to score sentiment of domain-specific documents. Sets of high-sentiment documents having positive and negative polarities are identified. The n-grams within the high-sentiment documents are filtered to remove extremely common n-grams. The filtered n-grams are saved as a domain-specific sentiment lexicon and are used as features in a model. The model is trained using a set of training documents which may be manually or automatically labeled as to their overall sentiment to produce sentiment scores for the n-grams in the domain-specific sentiment lexicon. This lexicon is used by the domain-specific sentiment classifier.

摘要： A system and method for determining a similarity between a document and a query includes building a weight vector for each of a plurality of documents in a corpus of documents stored in memory and building a weight vector for a query input into a document retrieval system. A weight matrix is generated which distinguishes between relevant documents and lower ranked documents by comparing document/query tuples using a gradient step approach. A similarity score is determined between weight vectors of the query and documents in a corpus by determining a product of a document weight vector, a query weight vector and the weight matrix.

摘要： Embodiments employ knowledge from network searches to enrich features useable to describe an advertisement. Advertisement content may be segmented to generate key phrases that are rank ordered based on a phrase's pointwise mutual information value with Ad keywords and term frequency-inverse document frequency (TF-IDF) scores. These key phrases are employed to generate a plurality of query searches that are performed to generate a plurality of search result snippets. The snippets are then analyzed and ranked to identify query expansion features having a TF-IDF value over a given threshold. A subset of these ranked phrases are combined with the Ad keywords to be used to rebuild an Ad index for the given advertisement. When content is to be delivered to a client device, content keywords are compared to the Ad index to select an advertisement to be provided with the content to the client device.
摘要翻译：实施例采用来自网络搜索的知识来丰富可用于描述广告的特征。广告内容可以被分割以产生基于具有广告关键词和术语频率 - 逆文档频率（TF-IDF）分数的短语的点互信息值进行排序的关键短语。采用这些关键短语来产生多个查询搜索，以便生成多个搜索结果片段。然后对片段进行分析和排序，以识别具有超过给定阈值的TF-IDF值的查询扩展特征。将这些排名短语的一部分与用于重建给定广告的广告索引的广告关键字相结合。当将内容传送到客户端设备时，将内容关键字与广告索引进行比较，以选择要向客户端设备提供内容的广告。
