Digital image data including discrete photographic images of a variety of different subjects, times, and so forth, are collected and analyzed to identify specific features in the photographs. In an embodiment of the invention, distinctive markers are distributed to aid in the identification of particular subject matter. Facial recognition may also be employed. The digital image data is maintained in a database and quarried in response to search requests. The search requests include criteria specifying any feature category or other identifying information, such as date, time, and location that each photograph was taken, associated with each photograph. Candidate images are provided for review by requesters, who may select desired images for purchase or downloading.

A methodology through which a host site may automatically insert relevant links into a set of text. In this methodology, the contents of the text are compared against a database containing character strings, and the character strings from the database contained in the text are identified. Each of the character strings in the database has an associated link that connects to other webpages on the same website or other websites. For each character string of the database found in the contents of the text, the associated link is inserted into the text. In this way, only relevant links are inserted into the text.

The invention provides, in one aspect, a method of searching an RDF triples data store of the type in which the triples are maintained in accord with a first storage schema. The method includes inputting a first query specifying RDF triples that are to be identified in the data store. That first query assumes either (i) that the triples are stored in a schema-less manner (i.e., with no storage schema) or (ii) that the triples are maintained in accord with a second storage schema that differs from the first. The method further includes generating, from the first query, a second query that specifies those same RDF triples, yet, that reflects the first storage schema. That second query can be applied to the RDF triples data store in order to identify and/or retrieve the desired data.

A method for detecting and locating occurrence in a data stream of any complex string belonging to a predefined complex dictionary is disclosed. A complex string may comprise an arbitrary number of interleaving coherent strings and ambiguous strings. The method comprises a first process for transforming the complex dictionary into a simple structure to enable continuously conducting computationally efficient search, and a second process for examining received data in real time using the simple structure. The method may be implemented as an article of manufacture having a processor-readable storage medium having instructions stored thereon for execution by a processor, causing the processor to match examined data to an object complex string belonging to the complex dictionary, where the matching process is based on equality to constituent coherent strings, and congruence to ambiguous strings, of the object complex string.

In an internet based system, a method of ranking products includes storing and outputting data identifying a plurality of suggested paradigms. The suggested paradigms each includes a set of suggested weighting factors that represent a specific consumer preference. A consumer selects one of the suggested paradigms and further inputs a set of weighting factors that includes at least one of the suggested weighting factors from the selected paradigm. The consumer thereafter inputs a query related to a product that is received by a server. A server generates and returns a ranking of a plurality of products based on the set of weighting factors input by the consumer and stored data related to a plurality of products, as a response to the query.

Classifying an electronic document in a computer-based system is disclosed. For each classification instance in a plurality of classification instances, a confidence data indicating a degree of confidence that the electronic document is associated with that classification instance is determined. A classification, based on a first classification instance in the plurality of classification instances, is assigned without human intervention to the electronic document if the confidence data associated with the first classification instance exceeds a first threshold.

Techniques to improve query caching performance by efficiently selecting queries stored in a cache for evaluation and increasing the cache hit rate by allowing for inexact matches. A list of candidate queries stored in the cache that potentially could be used to answer a new query is first determined. This list may include all cached queries, cached queries containing exact matches for select list items, or cached queries containing exact and/or inexact matches. Each of at least one candidate query is then evaluated to determine whether or not there is a cache hit, which indicates that the candidate query could be used to answer the new query. The evaluation is performed using a set of rules that allows for inexact matches of aggregates, if any, in the new query. A query plan is generated for the new query based on a specific candidate query with a cache hit.

In one embodiment, scanning data is received for wireless access points whose wireless signals were observed by the one or more scanning devices in a target area. For each group of scanning data that shares a common identifier of a Wi-Fi access point, a centroid of the scanning data is determined, a set of scanning data of the group that exceeds a threshold distance from the centroid is designated as having potential error, and a location of the Wi-Fi access point is calculated. The calculated location of the Wi-Fi access point for each group of scanning data is stored in a reference database. Upon receiving a request for a location of a mobile device, an identity of one or more Wi-Fi access points in range of the mobile device is determined, and the location of the mobile device is computed using calculated locations from the reference database.

Embodiments of the disclosed innovations provide systems and methods for locating data associated with rendered documents. Some embodiments support the use of a handheld document data capture device.
