摘要： Improved privacy preservation techniques are disclosed for use in accordance with data mining. By way of example, a technique for preserving privacy of data records for use in a data mining application comprises the following steps/operations. Different privacy levels are assigned to the data records. Condensed groups are constructed from the data records based on the privacy levels, wherein summary statistics are maintained for each condensed group. Pseudo-data is generated from the summary statistics, wherein the pseudo-data is available for use in the data mining application. Principles of the invention are capable of handling both static and dynamic data sets.

摘要： Techniques are disclosed for detecting new events in a video stream that yield improved detection efficiency in real time. For example, a method determines whether a given event is a new event in a video stream. The video stream includes a plurality of events. A first step extracts a first set of features (e.g., text features) from the given event. The first set of features is computationally less expensive to process as compared to a second set of features (e.g., image features) associated with the given event. A second step computes one or more first dissimilarity values between the given event and one or more previous events in the video stream using only the first set of features when one or more first dissimilarity criteria exist. A third step determines whether the given event is a new event based on the one or more computed first dissimilarity values.

摘要： Methods and apparatus for performing intelligent crawling are provided. Particularly, the intelligent crawling techniques of the invention provide a crawler mechanism which is capable of learning as it crawls in order to focus the search for documents on the information network being explored, e.g., world wide web. This crawler mechanism stores information about the crawled documents as it retrieves the documents, and then uses the information to further focus its search appropriately. The inventive techniques result in the crawling of a small percentage of the documents on the world wide web.

摘要： Distributed privacy preserving data mining techniques are provided. A first entity of a plurality of entities in a distributed computing environment exchanges summary information with a second entity of the plurality of entities via a privacy-preserving data sharing protocol such that the privacy of the summary information is preserved, the summary information associated with an entity relating to data stored at the entity. The first entity may then mine data based on at least the summary information obtained from the second entity via the privacy-preserving data sharing protocol. The first entity may obtain, from the second entity via the privacy-preserving data sharing protocol, information relating to the number of transactions in which a particular itemset occurs and/or information relating to the number of transactions in which a particular rule is satisfied.

摘要： A method of performing a flexible similarity search is provided. In one embodiment, the method comprises the steps of: (i) constructing an indexed representation of one or more documents to be used in the similarity search; (ii) specifying a target document and a similarity function to be used for the search of the one or more documents for which the indexed representation is constructed; and (iii) finding a document among the one or more documents for which the indexed representation is constructed which is similar to the target document, based on the specified similarity function. Thus, the invention creates a universal index for text similarity searches so that a user can specify a function at the time of query.

摘要： Periodic patterns in time series data can be hierarchical in nature, where a higher level pattern may comprise repetitions of lower level patterns. In the presence of noises, these repetitions of lower level patterns may not be perfect. A novel model, namely a meta-pattern, is provided in accordance with the present invention to capture these higher level patterns. The meta-pattern can not only provide a more compact representation of patterns but also capture the regularities of pattern evolutions, which may not be expressed by previous models due to the presence of noise. A method is provided to mine meta-patterns in an iterative manner by discovering meta-patterns and their supporting subsequences in the form of lists of segments of contiguous repetitions of a meta-pattern. The number of pattern repetitions in each said segment is at least a predefined threshold min_rep and the distance between any two adjacent segments is at most a predefined threshold max_dis.

摘要： Methodologies are provided which use affinity lists in order to perform query retrieval more effectively and efficiently. The invention comprises a two phase method. In the first phase, we find a threshold number k of candidate documents which are retrieved by the method. In the second phase, we calculate the affinity value to each of these k documents and report them in ranked order of affinities. The first phase of finding the k most valuable candidates is accomplished using an iterative technique on the affinity lists. Once these candidates have been found, the affinity to each document in the set is obtained, and the resulting documents are rank ordered by affinity to the target document.

摘要： The present invention is an apparatus, system, and method for providing reservations for restroom use. In one embodiment, a passenger on an airplane may submit a reservation request to the system for restroom use. The reservation system determines when the request can be accommodated and notifies the passenger when a restroom becomes available. The system improves airline safety by minimizing the time passengers spent standing while an airplane is in flight.

摘要： A proxy strategy not only caches objects but actively sets update schedules for channel information disseminated from different servers. Based on available bandwidth, this proxy strategy formulates a mathematical function that can be solved to establish the proxy update schedules by maximizing the overall currency of information received by the clients. Clients whose update requests do not result in receiving the most upto-date information for a given channel may also be recorded. After the next scheduled proxy update for a given channel, the proxy actively sends the most up-to-date information for this channel to the recorded clients. The client interest for a given channel is measured based on the client updates the proxy received since last scheduled update for this channel, and the currency of information received by these clients. A dynamic update can be performed by the proxy for channels with high client interest before their respective scheduled updates based on the available bandwidth. Upon performing a dynamic update for a given channel, the proxy can delay the next schedule update for this channel by a whole regular proxy update interval.
摘要翻译：代理策略不仅缓存对象，而且主动设置从不同服务器传播的渠道信息的更新计划。基于可用带宽，该代理策略制定一个数学函数，可以通过最大化客户端接收的信息的总体货币来解决以建立代理更新计划。更新请求不会导致接收给定频道最新信息的客户端也可以被记录。在给定频道的下一个计划的代理更新之后，代理将主动向记录的客户端发送该频道的最新信息。基于客户端更新从该频道上次调度更新以来收到的代理以及这些客户端收到的信息的货币，来衡量给定频道的客户兴趣。可以由代理针对具有高客户机感兴趣的信道在基于可用带宽的各自的调度更新之前对其进行动态更新。在对给定频道执行动态更新时，代理可以通过整个常规代理更新间隔延迟该频道的下一个调度更新。

摘要： A method and system provides collaborative caching of transformed Web objects in a proxy network. The proxies collaboratively provide a set of object transformations by partitioning the different types of object transformations, and caching the transformed Web objects among proxies in order to reduce duplicate object transformation and caching effort. The transformations may include language translations, currency conversions, units of measure conversions, shipping cost calculations and sales taxes calculations. Other transformations are also possible.
