Abstract: There is a need for more effective and efficient document summarization. This need can be addressed by, for example, techniques for contextual summarization using semantic intelligence. In one example, a method includes identifying a plurality of senses associated with a plurality of words in a document; for each word-sense pair, determining a word-sense probability score; determining, based at least in part on each word-sense probability score for a word-sense pair, one or more context buckets for the document and one or more sense buckets for the document; determining, based at least in part on the one or more context buckets for the document and the one or more sense buckets for the document, the contextual summarization of the document; and performing one or more document processing actions based at least in part on the contextual summarization.

Abstract: There is a need for solutions that perform preprocessing and/or searching of documents with semantic intelligence. This need can be addressed by, for example, by performing pre-processing of each document of a plurality of documents to generate an indexed representation for the document by identifying sentences in the document; determining, for each n-gram of one or more n-grams associated with the document, one or more n-gram semantic scores based semantic proximity indicators for the n-gram; determining, based at least in part on each one or more n-gram semantic scores, one or more sentence semantic labels for each sentence in the document; and determining the indexed representation for the document based at least in part on the one or more sentence semantic labels for the document; performing the search query based each indexed representation associated with a document; and transmitting the result to a computing device associated with the search query.

Abstract: Systems, apparatuses, methods, and computer program products are disclosed for searching electronic documents. An example method includes receiving a set of electronic documents, wherein each electronic document in the set of electronic documents comprises a set of sentences. The example method further includes generating a contextual index that associates each sentence with one or more of contexts. The example method further includes receiving an electronic search query comprising a plurality of search terms. Subsequently, the example method includes generating a contextual search ranking for a subset of the set of electronic documents based on the search terms and the contextual index.

Abstract: An exemplary security system includes a credential holder having a credential database that contains specified secured area credential information indicating at least one secured access location between a specified secured area and a specified adjacent area where the credential information is valid for authorized access. An access control device at a selected position corresponding to the secured access location is configured to receive the credential information when the credential holder is near the access control device. A processor of the access control device has stored access control information including indications of the specified secured area, the specified adjacent area and the secured access location. The processor autonomously determines that access to the specified secured area will be granted when the received credential information corresponds to the stored indications.

Abstract: Methods for compression of sonic log data include STC processing, sorting peak components in the sonic data; filtering the sorted peak components to remove high-frequency portions in the peak components; and decimating the filtered peak components according to a selected ratio to produce compressed data. One method for telemetry transmission of downhole sonic log data includes sorting peak components in the sonic log data; compressing the sorted peak components to produce compressed data; packing the compressed data to produce data packets for telemetry transmission; and sending the data packets using telemetry.

Abstract: An improved physical access control system has an online portion and an offline portion. A smartcard is configurable to transport access control information between the online portion and offline portion. The smartcard is further configurable to receive an offline reader identifier from an offline reader, and to control access of the smartcard holder to an offline entry/exit point. The smartcard is further configurable to carry a revoked list that is transmitted to each offline reader accessed. Methods of operating the improved physical access control system are also disclosed.
