    • The relevance of documents is automatically determined based upon a weighted tree. Terms considered to be relevant are assigned to the leaf nodes of a tree data structure. A location can also be specified in a leaf node, indicating where in a document the term must appear to be considered relevant. Internal nodes of the tree are assigned operators (e.g., add, maximum or minimum). The connections between nodes are assigned weights. A relevance value for a given document is calculated as a function of occurrence in the document of terms assigned to leaves, operators assigned to internal nodes, and weights assigned to the associated node connections. Weighted trees can be used to process search queries. Documents with high relevance scores calculated against the tree can be returned to a user as the results to a query.
    • 文档的相关性是根据加权树自动确定的。 被认为相关的术语被分配给树状数据结构的叶节点。 也可以在叶节点中指定位置,指示文档中的哪个字词必须看起来被认为是相关的。 树的内部节点被分配运算符(例如,添加,最大或最小)。 节点之间的连接被分配权重。 给定文档的相关性值作为分配给叶子的文档的文档,分配给内部节点的运营商以及分配给关联节点连接的权重的函数计算。 加权树可以用于处理搜索查询。 根据树计算的具有高相关性分数的文档可以作为查询的结果返回给用户。

    • Thumbnail image substitution is described. In embodiments, a navigation input is received that is effective to move from a first view of a media content page to a second view of the media content page. The second view includes a region of the media content page that is not included in the first view of the media content page. A thumbnail image is displayed in the region of the media content page that is not included in the first view and that will display the media content. The thumbnail image is replaced to display the media content in the region of the media content page that corresponds to the second view of the media content page.

    • As a mobile device moves from one location area to another, the mobile device detects the different location identifiers broadcast by the wireless network(s) in those locations areas. The mobile device stores the location identifier for the last location area in which the mobile device was located. By comparing a received location identifier to the stored location identifier, the mobile device determines if the mobile device has entered a new location area. If so, the mobile device sends a location update request. In one embodiment, if the location update request is for a location area to which access by the mobile device is restricted, the network sends a communication to the mobile device that triggers the mobile device to update a location identifier stored at the mobile device to the location identifier for the restricted location area so that the mobile can update the network after entering/selecting a different location area.
    • 随着移动设备从一个位置区域移动到另一个位置区域,移动设备检测由那些位置区域中的无线网络广播的不同位置标识符。 移动设备存储移动设备所在的最后位置区域的位置标识符。 通过将接收到的位置标识符与存储的位置标识符进行比较,移动设备确定移动设备是否已经进入新的位置区域。 如果是,则移动设备发送位置更新请求。 在一个实施例中,如果位置更新请求是针对移动设备的访问受到限制的位置区域,则网络向触摸移动设备的移动设备发送通信,以将存储在移动设备处的位置标识符更新为 用于受限位置区域的位置标识符,使得移动台可以在进入/选择不同位置区域之后更新网络。

    • Paging of a mobile device within a mobile pool area serviced by two or more mobile switching nodes is reduced using logical paging areas. The mobile pool area includes a plurality of location areas, each serviced by the two or more switching nodes. In addition, the mobile pool area is divided into multiple logical paging areas, in which each logical paging area includes at least two location areas. Upon receiving a mobile terminated call for the mobile device, if the location area of the mobile device is unknown, the logical paging area within which the mobile device is located is determined in order to page the mobile device and deliver the mobile terminated call to the mobile device.

    • A method for identifying common multiphone units to add to a unit inventory for a text-to-speech generator is disclosed. The common multiphone units are units that are larger than a phone, but smaller than a syllable. The method slices each syllable into a plurality of slices. These slices are then sorted and the frequency of each slice is determined. Those slices whose frequencies exceed a threshold are added to the unit inventory. The remaining slices are decomposed according to a predetermined set of rules to determine if they contain slices that should be added to the unit inventory.
    • 公开了一种用于识别用于添加到文本到语音生成器的单元库存的公共多声单元的方法。 普通的多声道单元是比手机大的单位,但小于音节。 该方法将每个音节分成多个切片。 然后对这些切片进行排序,并确定每个切片的频率。 频率超过阈值的那些切片被添加到单位库存中。 剩余的切片根据预定的一组规则分解,以确定它们是否包含应该添加到单元库存的切片。
