Delivering a search result is disclosed. A query is received. A term in the query that is a first portion of an abbreviation pair is identified. A second portion of the abbreviation pair is determined. A search result for the query is determined based at least in part on the second portion of the abbreviation pair and the search result is returned.

Topic relevant abbreviations

Category affinity may be used as a consideration in providing search results. A taxonomy of substantive categories is created and/or obtained. A corpus of document is compared with the taxonomy to determine the category(ies) with which the documents affine. A query is also compared with the taxonomy to determine the category(ies) with which the query affines. A document may receive a category score based on how well the document's category(ies) match the query's category(ies). This document score may be combined with other scores, such as a text score, a link score, and a distance score, and/or any other factors, to determine an overall relevance score. The relevance score may then be used to rank and present search results.

Information retrieval using category as a consideration

Delivering a search result is disclosed. A category is associated with a document based at least in part on one or more scores that measure the relevance of that document to a base category. A search query is obtained. One or more results is delivered in a manner that includes an indication of at least one category with which the result is associated.

Delivering search results

One embodiment of the present invention provides a system that facilitates automatically organizing digital images using metadata which is embedded in the digital images. The system operates by receiving a digital image with embedded metadata, wherein the embedded metadata includes Global Positioning System (GPS) data. The system uses the embedded metadata, including the GPS data, to identify additional metadata associated with the digital image. The system then saves the digital image on a storage medium. In addition, the system saves the embedded metadata and the additional metadata on the storage medium in a searchable format.

Method and apparatus for organizing digital images with embedded metadata

The method disclosed herein effectively caches timestamps in the memory of a query server. Each index file contains a base time and a set of documents with encoded timestamps. The base timestamp stored represents the index build time. The indexer encodes the timestamp of each document stored in the data directory. The difference of the absolute timestamp and the base timestamp is telescopically quantized into segmented time units. The compressed value of the segmented time units is stored in the index. During the querying process, the encoded timestamps for an individual document is recreated by applying a decoding process carried out in the query server. The reverse of the telescopic quantization is conducted to determine the absolute timestamp.
