A method and apparatus are provided for building a searchable multi-dimensional index tree that indexes a plurality of data objects. In one aspect of the invention, the index tree divides dataspace into three subspaces and indexes the data objects using a single dimension. If too many data objects map to the same point in that dimension, the dimension is switched to a new dimension of the data object and the data object is indexed using the new dimension. A split node having a split value is used to keep track of the indexing. In another aspect of the invention, the index tree divides dataspace into two subspaces, and equal bits are used in the split nodes to track the content of the data objects in the subspaces. If too many data objects sharing the same key within the same dimension map to a single point, then the dimension is switched to a new dimension and the data objects are indexed using the new dimension. Also disclosed is the multi-dimensional index tree itself as well as a router that uses the multi-dimensional index tree of the present invention to provide packet classification functions.

A system and related techniques execute search queries against both remote Internet or other search services, as well as local or remote email stores. A user may access a search service Web site or other search interface, and enter search inputs or terms. That search input may be transmitted to a remote search service via the Internet or other network, as well as through access logic which communicates the same search inputs to the user's local or remote email store. Web sites as well as email messages or other content that matches the search input may be retrieved both from the remote search service as well as the email store, and presented to the user in combined or separate fashion. The access logic may manage the transmission of necessary authentication credentials to remote servers or otherwise to access and retrieve the email portion of the results. According to embodiments, email search results may be cached to improve access time and integration with results retrieved from the search service.

The present invention relates to a system and methodology to facilitate extraction of information from a large unstructured corpora such as from the World Wide Web and/or other unstructured sources. Information in the form of answers to questions can be automatically composed from such sources via probabilistic models and cost-benefit analyses to guide resource-intensive information-extraction procedures employed by a knowledge-based question answering system. The analyses can leverage predictions of the ultimate quality of answers generated by the system provided by Bayesian or other statistical models. Such predictions, when coupled with a utility model can provide the system with the ability to make decisions about the number of queries issued to a search engine (or engines), given the cost of queries and the expected value of query results in refining an ultimate answer. Given a preference model, information extraction actions can be taken with the highest expected utility. In this manner, the accuracy of answers to questions can be balanced with the cost of information extraction and analysis to compose the answers.

A method and system for providing a network-based photosharing service is disclosed. The photosharing service includes a central photosharing site having a server, and a plurality of peer nodes each containing digital images. The method and system include associating metadata with each image that is to be shared. The images are shared by uploading the metadata associated with each image from the peer nodes to the peer server, while maintaining storage of the images on the respective peer nodes. In response to the peer server receiving search criteria based on the metadata submitted from a first one of the peer nodes, the peer server returns a list of image locators for images matching the search criteria to the first peer node. The method and system further include dynamically generating on the first peer node an image album that contains at least a portion of the matching images.

A search system analyzes a user's search requests and identifies prior semantically-similar search requests that have provided well-received results. Each search request is classified, based on the semantics of the search request, and the user's satisfaction with the effectiveness of the search request is monitored and recorded within the determined class (or set of classes). As a particular user's search session continues, the classification of the user's search request is also used to identify other searches in the determined class, and the user is provided the option of modifying or replacing the user's current request with one of these semantically similar searches. The system may also be configured to identify the most favored results provided by these semantically similar searches, and allow the user to select from among these results. The system may also provide incremental updates over time, as new results or new semantically-similar search requests are found.
