Sentiment polarity classification algorithms optionally determine whether opinion information comprises a positive or negative opinion and assign a polarity score. An influencer score of the opinion holder is optionally assigned to the opinion information. Exibir menos

Methods and apparatus are provided for automatically transcoding media files. An exemplary method comprises obtaining an input media file having an input file format and encoded with a codec of a first type; automatically determining output media file formats for transcoding the input media file based on statistics of previously transcoded files and statistics of trending media formats for previously downloaded files; and transcoding the input media file into transcoded output media files using… Exibir mais

Methods and apparatus are provided for automatically transcoding media files. An exemplary method comprises obtaining an input media file having an input file format and encoded with a codec of a first type; automatically determining output media file formats for transcoding the input media file based on statistics of previously transcoded files and statistics of trending media formats for previously downloaded files; and transcoding the input media file into transcoded output media files using a codec of a second type to obtain the determined output media file formats. The output media file formats can be automatically determined using a weighting scheme. Transcoding algorithms are optionally automatically selected based on transcoding algorithms previously used to transcode proximally similar files as the input media file. Input files can be dynamically prioritized for transcoding based on a complexity rating of the determined output media file formats and a ranking of selected transcoding algorithms Metadata is optionally generated for transcoded output media files and stored in the transcoded output media files and/or a separate media catalogue.

Scale-out network attached storage (NAS) file systems can employ an Ingest, Transform, Store (ITS) framework for data processing. In one aspect, the ITS-NAS file systems comprise NAS nodes and high performance computing (HPC) nodes that operate under a common operating system and that are coupled to each other via a common high-bandwidth, low-latency private network infrastructure. The NAS nodes can present data to the HPC nodes as well as dispatch the execution of transform services to the HPC… Exibir mais

The NAS nodes can present data to the HPC nodes as well as dispatch the execution of transform services to the HPC nodes. The ITS-NAS file systems enable massive parallelization of operations on files, for example, complex distributed operations on large files and/or simple parallel operations on large collections of small files, all within the same hardware and software architecture Exibir menos

Described herein are technologies pertaining to automatically summarizing contents of a dataset and visualizing a summary of the dataset together with summaries of other datasets. A schema that defines the structure and content of a dataset is received, and pre-processing is undertaken on the schema to generate an enriched schema. Portions of the enriched schema are selected to generate a semantic summary of the schema, which is included with at least one exemplary entry of the dataset to… Exibir mais

A hot folder mechanism is employed to provide a truly integrated architecture for easy-to-use, easy-to-deploy scale-out computation and scale-out storage. A folder of an Ingest, Transform, Store (ITS)-Network attached storage (NAS) system can be configured as “hot.” The configured hot folder can then detect changes on its content, analyze such content, perform transform services on the content, and output the computation results as files on other specified output folders. In one aspect, file… Exibir mais

An exemplary method comprises providing a plurality of databases having different database types; translating ontology definition language database commands obtained from a user into a plurality of data definition language and/or data manipulation language commands supported by the different database types in order to replicate data from the user to each of the different database types; obtaining a query specified in a query language of a given database; and delegating the query to the given database. A plurality of cluster gateways optionally manage a corresponding plurality of clusters of database instances and wherein queries are delegated to a given database instance by delegating the queries to the appropriate cluster gateway. Dark data that was not queried by any supported query language in a predefined period of time can be detected. Exibir menos
