    • A method, an apparatus and an article of manufacture for modeling a task-site allocation. The method includes generating a task-site allocation network based on at least one site-task pair and at least one site-centric constraint of at least two sites, wherein generating a task-site allocation network comprises generating a task-specific constraints model based on task context information and generating a task-site pair that satisfies at least one constraint based on the task-specific constraints model, and determining a preferred allocation of task to site by comparing estimated task-site allocation cost between a single site allocation and a distributed site allocation among the at least two sites.

    • A method and system for optimizing resource usage in an information retrieval system. Meta information in query results describes data items identified by identifiers. A chunk of the identifiers and a set of meta information are loaded into a first cache and a second cache, respectively. A portion of the set of meta information is being viewed by a user. The portion describes a data item identified by an identifier included in the chunk and in a sub-chunk of identifiers that identifies data items described by the set of meta information. If a position of the identifier in the sub-chunk satisfies a first criterion, then a second set of meta information is preloaded into the second cache. If a position of the identifier in the chunk satisfies a second criterion, then a second chunk of the identifiers is preloaded into the first cache.
    • 一种用于优化信息检索系统中的资源使用的方法和系统。 查询结果中的元信息描述了标识符标识的数据项。 标识符和一组元信息的块分别被加载到第一高速缓存和第二高速缓存中。 一组元信息的一部分正在由用户查看。 该部分描述由标识符识别的标识符的数据项,所述标识符包括在标识符的子块中以及标识符的子块中,该标识符标识由所述一组元信息描述的数据项。 如果子块中的标识符的位置满足第一标准,则将第二组元信息预加载到第二高速缓存中。 如果组块中的标识符的位置满足第二标准,则将第二组标识符预加载到第一高速缓存中。

    • Computer-implemented methods, systems, and computer program products for autonomic recovery of messages are provided. A computer-implemented method includes creating a temporary file for a communication session. The temporary file identifies a communication partner to the communication session and a start time of the communication session. The computer-implemented method also includes monitoring the communication session. Upon the occurrence of a triggering event, the computer-implemented method includes logging the time of the triggering event in the temporary file, logging the time of any messages received after the time of the triggering event, and storing the messages in the temporary file. The computer-implemented method further includes presenting the messages in response to initiation of another communication session with the communication partner.

    • A method and system that allows efficient shredding of large instances of hierarchical data structures into relational data structures. Large instances of hierarchical data structures, which are able to be larger than the random access storage of a computer used to shred them into relational data structures, are incrementally shredded into a temporary storage. When the amount of data shredded into the temporary storage reaches or exceeds a predetermined commit count, the data in the temporary storage is transferred to a relational data structure maintained by a relational database manager. A Document Type Description annotation is provided to allow the end user to specify execution order for SQL commands and to specify commit count values.
    • 一种方法和系统,允许将大型实例的分层数据结构高效地分解成关系数据结构。 能够比用于将它们分割成关系数据结构的计算机的随机存取存储器更大的分级数据结构的大型实例被递增地切割成临时存储器。 当切入临时存储器的数据量达到或超过预定提交计数时,临时存储器中的数据被传送到由关系数据库管理器维护的关系数据结构。 文档类型说明注释用于允许最终用户指定SQL命令的执行顺序并指定提交计数值。
