Abstract: An offline semantic processor of a resource-constrained voice-enabled device such as a mobile device utilizes an offline grammar model with reduced resource requirements to parse voice-based queries received by the device. The offline grammar model may be generated from a larger and more comprehensive grammar model used by an online voice-based query processor, and the generation of the offline grammar model may be based upon query usage data collected from one or more users to enable a subset of more popular voice-based queries from the online grammar model to be incorporated into the offline grammar model. In addition, such a device may collect query usage data and upload such data to an online service to enable an updated offline grammar model to be generated and downloaded back to the device and thereby enable a dynamic update of the offline grammar model to be performed.

Abstract: A method includes receiving a first set of de-identified records for individuals from a first type of database for a first set of entities. The first type of database does not include longitudinal information that links the first set of de-identified records across the first set of entities. The method includes receiving a second set of de-identified records for a single individual from a second type of database for a second set of entities. The second type of database includes longitudinal information that links the second set of de-identified records across the second set of entities including over time. The method includes integrating the first type of databases and the second type of databases, which matches the individuals and the single individual. The method includes adding longitudinal information to the first type of database for the individuals based on the longitudinal information of the second type of database.

Abstract: The invention relates to a method for finding a position of a data pattern in reference data. For this a reference index data structure comprising a reference data structure, a sorted index and a jump table is generated. The sorted index comprises for each position in the reference data structure an entry. Each entry comprises a position field which value refers to an associated position in the reference data structure. By means of the position a reference data pattern corresponding to said position could be reconstructed from the reference data structure. The entries of the sorted index are sorted according to the reference data pattern associated with the value in the position field. A search is performed through the sorted index by reconstructing a reference data pattern from the reference data structure and comparing it with the data pattern to be matched.

Abstract: A retrieval system retrieves content data stored in a database using an index. The retrieval system includes a first registration unit configured to register a set definition including an index object item indicating a data item serving as the index and an acquisition condition for acquiring the content data from the database; an acquisition unit configured to acquire, when the set definition is registered by the first registration unit, content data included in the set definition, which satisfy the acquisition condition, from the database; and a generation unit configured to extract the index object item included in the set definition, to generate the index, in the content data acquired by the acquisition unit.

Abstract: Embodiments of the present invention provide a metadata querying method and apparatus. The method includes: sampling at least one piece of first metadata from to-be-searched-for metadata; using at least a part of feature values in each piece of the sampled first metadata as an index, and searching a sparse index table preset in a memory for a corresponding container identifier, where the sparse index table records container identifiers, and a location index of each container identifier in the index table is at least a part of feature values of metadata stored in a container corresponding to the container identifier; selecting, according to the number of times that a same container identifier is found, a container corresponding to a container identifier that meets a set condition; loading metadata in the selected container into a metadata cache; and searching the metadata cache for a data block that is the same as the to-be-searched-for metadata. In the embodiments of the present invention, querying performance can be improved and occupied memory space can be reduced.

Abstract: Examples of the present disclosure describe systems and methods for enhancing the privacy of a personal search index. In some aspects, a personal cleartext document may be used to generate an encrypted document digest and an encrypted document on a first device. A second device may decrypt the document digest, build a personal search index based on the decrypted document digest, and store the encrypted document in a data store. The first device may subsequently receive a cleartext search query that is used to query the personal search index on the second device for encrypted documents.

Abstract: A method for updating a database for anonymous visitor tracking includes receiving (402) at least one cookie from a visitor to a first domain name. Based on the at least one cookie, the method determines (404) whether the visitor has an associated unique identity for the first domain name. When the visitor does not have an associated unique identity, the method includes determining (406), for each affiliated domain name in a plurality of affiliated domain names, whether the visitor has an associated unique identity for the affiliated domain name. When the visitor does not have an associated unique identity for the affiliated domain name, the method includes generating (408) a unique identity associated with the visitor and storing the unique identity with the first domain name in an associated identity database. A record associated with the unique identity is updated (410) with a time at which the visitor navigated to the first domain name. An updated first-party cookie, including the unique identity, is generated and transmitted for storage on a device associated with the visitor.
