    摘要： A data-driven, hierarchical information search and navigation system and method enable search and navigation of sets of documents or other materials by certain common attributes that characterize the materials. The invention includes several aspects of a data-driven, hierarchical search and navigation system that employs this search and navigation mode. The search and navigation system of the present invention includes features of an navigation interface, a search interface, a knowledge base and a taxonomy definition process and a classification process for generating the knowledge base, a graph-based navigable data structure and method for generating the data structure, World Wide Web-based applications of the system, and methods of implementing the system. Users are able to search or browse a particular collection of documents by selecting desired values for the attributes or by searching the attribute-value pairs. A data-driven, hierarchical information search and navigation system and method enable this navigation mode by associating terms with the materials, defining a set of hierarchical relationships among the terms, providing a guided navigation mechanism based on the relationship between the terms, and providing a search mechanism that can respond to free-text queries with single-term or multi-term interpretations. In another aspect of the invention, implementations of the invention may be scalable through parallel or distributed computation.

    摘要： The foregoing needs and other needs are addressed by the present invention, which provides, in one aspect, a mechanism for locating a data object. According to an aspect of the present invention, key values for data objects are generated, each key value may contain a first subkey value and a second subkey value. A mapping associates the first subkey values with storage locations. A particular first subkey value is mapped to storage location that contains second subkeys of a set of key values that correspond to the first subkey value. The storage location also includes additional information that may be used to locate objects associated with the set of key values.

    摘要： An Internet Protocol driver executed by a network interface card, or a network address translation module, includes a mechanism that enables a server to bypass packets associated with certain destinations, sources, or a combination of the two based upon their IP address. When a packet arrives at the network interface card, the driver extracts a source IP address and a destination IP address from the packet. The driver searches a table to locate a rule matching one of the addresses. If a match is found, the packet is bypassed. If no match is found, the packet is sent on to an indexing and caching server for further processing. The bypass rules may be adaptively and dynamically generated when a message causes a remote server to respond with an error code. The dynamically generated bypass rules prevent the first server from sending subsequent requests to the remote server, thereby insulating the indexing and caching server from unnecessary network traffic.

    摘要： A method for garbage collection in a cache of information objects is provided. A non-volatile storage device is segmented into storage areas called pools. Each pool has a pool header and a plurality of arenas. Each arena stores one or more fragments of an object. Header information for each arena is stored in the pool header in which that arena is stored. Each fragment comprises a fragment header and fragment data. The garbage collection periodically selects a pool that is storing an amount of data greater than a minimum storage value or high water mark. Each arena in the pool is examined and selected for garbage collection according to selection criteria. Each fragment within a selected arena is examined based upon a second set of selection criteria that determine whether the fragment is retained or deleted. If the fragment is deleted, all other fragments in the storage device that relate to that fragment's object are also deleted. When a fragment arena is retained, it is moved into contiguous storage in another available arena. A computer program product, computer apparatus, and data signal embodied in a carrier wave, configured to carry out the steps of the method, are also disclosed.

    摘要： A high-performance cache is disclosed. The cache is designed for time- and space-efficiency for a diverse range of information objects. Information objects are stored in portions of a non-volatile storage device called arenas, which are contiguous regions from which space is allocated in parallel. Objects are substantially contiguously allocated within an arena and are mapped by name keys and content-based object keys to a tag table, an open directory, and a directory table. The tag table is indexed by the name keys, and stores references to sets in the directory table. The tag table is compact and therefore can be stored in fast main memory, facilitating rapid lookups. The directory table is organized so that at least a frequently-accessed portion of it also usually resides in fast main memory, which further speeds lookups. The tag and directory tables are organized to quickly determine non-presence of objects. Large objects may be chunked into fragments, which are chained using a forward functional-iteration mechanism, to prevent the need for mutating existing on-disk data structures. Garbage collection periodically moves objects within an arena or to other arenas so that inactive objects are deleted and free space becomes contiguous. Because the objects are substantially contiguously allocated, reading and writing an typical object requires only one or two disk head actuator movements; thus, the cache can efficiently and smoothly stream data off of the storage device, providing optimal delivery of multimedia objects. The disclosure also encompasses a computer apparatus, computer program product, and computer data signal embodied in a carrier wave that are similarly configured.

    摘要翻译： 公开了一种高性能缓存。 高速缓存旨在为各种信息对象提供时间和空间效率。 信息对象存储在称为区域的非易失性存储设备的部分中，这些区域是并行分配空间的连续区域。 对象在竞技场内基本连续分配，并通过名称键和基于内容的对象键映射到标签表，打开目录和目录表。 标签表由名称键索引，并存储对目录表中的集合的引用。 标签表是紧凑的，因此可以存储在快速主存储器中，便于快速查找。 目录表被组织，使得至少其频繁访问的部分通常也驻留在快速主存储器中，这进一步加快了查找速度。 标签和目录表被组织以快速确定不存在对象。 可以使用前向功能迭代机制将大对象分块成片段，以阻止对现有磁盘数据结构进行突变的需要。 垃圾收集会周期性地移动竞技场内的对象或其他场所，从而删除非活动对象并使可用空间变得连续。 由于物体基本连续分配，读取和写入典型物体仅需要一个或两个盘头致动器运动; 因此，高速缓存可以有效地平滑地将数据从存储设备流出，从而提供多媒体对象的最佳传送。 本公开还包括计算机设备，计算机程序产品和体现在类似配置的载波中的计算机数据信号。
