InactiveUS6988132B2Improve utilizationMaximize utilizationInterconnection arrangementsSpecial service for subscribersContext recognitionStatus changed
A system and method for identifying and establishing preferred modalities or channels for communications based on participants' preferences and capabilities is provided. In one approach, the system attempts to optimize the inferred or directly accessed preferences of a contactee given the accessed or inferred preferences, capabilities and goals of the contactor while keeping the rationale and context of the contactee private. Such optimization can be achieved using preferences and policies concerning handling the attempted contact based on a deterministic specification or through inferring context, content and task under uncertainty by employing decision-theoretic inferences to attempt to maximize the expected utility of the communication to the contactee. The methods may include a consideration of metadata within a standard schema that is transmitted along with a communication attempt, representing information about such attributes as the identity of the contactor, the task at hand, the overall context of the contactor, and the communication capabilities available to the contactor. The invocation of the communication service may be performed in a variety of ways, including single button invocations, and via a communication service that is more deeply integrated with other applications and functionalities. The service can also include automated rescheduling of communications based on a consideration of forecasts of availability of both the contactor and contactee.

Readability and context identification and exploitation
InactiveUS20070067294A1Targeted optimizationDigital data information retrievalDigital data processing detailsReading levelContext recognition
Search systems and methods address the subjective nature of the relevancy of matches to users' queries through the use of readability formulae. As a result, the documents are ranked by relevance not only to user queries, but specifically to the user. In one approach, the searchable web (or a searchable corpus of documents) is categorized on one or more servers. Each document is designated by reading level or other parameter(s) relevant to the user's reading ability. In one embodiment, searching is carried out utilizing the user's search query, and documents are ranked based on relevance to the query and on their degree of readability to the user—e.g., the degree to which the contents of each document correspond to the user's reading level. Advertisement displays may be targeted to both the search tokens entered and the user's age as determined from his reading level, rendering search-related advertisements significantly more effective in reaching their intended audiences.

A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN / UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN triggering initiation of the packet-switched handover from the GERAN / UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN / UTRAN cell.

Automatic detection and application of editing patterns in draft documents
ActiveUS20070106494A1Natural language data processingSpeech recognitionContext recognitionPaper document
An error detection and correction system extracts editing patterns and derives correction rules from them by observing differences between draft documents and corresponding edited documents, and / or by observing editing operations performed on the draft documents to produce the edited documents. The system develops classifiers that partition the space of all possible contexts into equivalence classes and assigns one or more correction rules to each such class). Once the system has been trained, it may be used to detect and (optionally) correct errors in new draft documents. When presented with a draft document, the system identifies first content (e.g., text) in the draft document and identifies a context of the first content. The system identifies a correction rule based on the first content and the first context. The system may use a classifier to identify the correction rule. The system applies the correction rule to the first content to produce second content.
