    摘要： Described herein are various technologies pertaining to provision of query suggestions to a user independent of a query log. Key phrases are automatically identified in documents of a document corpus, and a forward index and inverted index are generated. The forward index indexes key phrases by documents, and the inverted index indexes documents by key phrases. A query is received from a user, and documents relevant to the query are retrieved. Key phrases in the retrieved documents are identified via the forward index, and a subset of the key phrases are selected as query suggestions by determining coverage of the key phrases as identified in the inverted index.

    摘要： A method for providing searching and alerting capabilities in traffic content at access points in data networks is disclosed. Typical access points for Internet, intranet and wireless traffic are described. Traffic flow through an Internet Service Provider is used as a preferred embodiment to exemplify the data traffic used as the input source in the invention. The invention teaches how proper privacy and content filters can be applied to the traffic source. The filtered data stream from the traffic flow can be used to improve the quality of existing searching and alerting services. The invention also teaches how a cache can be developed optimized for holding fresh searchable information captured in the traffic flow. It is further disclosed how the said cache can be converted to a searchable index and either separately or in cooperation with external search indexes be used as a basis for improved search services. The invention also discloses how the traffic flow can be analyzed in order to derive added information for measuring document relevance, access similarity between documents, personalized ranking of search results, and regional differences in document accesses.

    摘要： In a method for determining contextual summary information across documents retrieved in response to a user query applied to a collection of documents the documents matching the query are identified. A query-dependent subsection of each of the matching documents is selected. Document properties associated with the document subsection are selected and associated with localized structures within the document. Relationships between localized document properties and user queries are determined and used to compute contextual summary information, whereby localized document properties are profiled across the retrieved documents in a contextual manner. The method allows a user query to select localized structures within a matching document and is generally applicable in information retrieval and the analysis of retrieved information.

    摘要： An ECG gated ultrasonic imaging compounding system and method for synthesizing a cineloop of a compound ultrasonic image such as a cardiac cycle is presented. In real-time operation, a series of image frames may be recorded at a frame rate over a cardiac cycle and stored in a cineloop memory. A second series of image frames are recorded over a second cardiac cycle. The image frames of the second cardiac cycle are frame-by-frame aligned in time and space with the corresponding image frames from the cineloop memory. The aligned frames are then combined to form a series of synthesized image frames which then replace the original image frames in the cineloop memory. Subsequent series of image frames are also combined with the synthesized image frames in the cineloop memory to form new synthesized image frames which then replace the old synthesized image frames in the image array, and so forth. The series of image frames may be triggered to begin at a cardiac event such as the R-event.
