Attributes in data records are identified. Episodes corresponding to the respective attributes include respective data records. The episodes are scored, where scoring of a particular one of the episodes is based on relative time densities between successive data records of the particular episode. A visualization of at least some of the episodes to provide an alert of time-dense episodes.

A method for generating sum maries of text is described. The method includes the step of extracting features from text of text lists from summaries. The explanatoriness of the text is then evaluated, wherein evaluating the explanatoriness of text includes evaluating the features of the text, including at least the step of evaluating the discriminativeness of the features of the text by comparing the text to a first text data set, wherein the first text data set is derived from a topic label. The evaluated text is then ranked based on the explanatoriness evaluation.

An open station as a stream analysis operator container is disclosed. In an example, a method is stored as instructions on computer readable media and executable by a processor. The method includes packaging graph-structured stream transformations into a topology of a top-level dataflow process including stream transformation operators (STOs) on open stations. The method also includes sending a tuple from one of the STOs to every other STO in the topology subscribed to a data stream of the tuple.
摘要:
Pixels representing attributes of data records are into discrete rings of a graphical visualization, where the discrete rings correspond to respective ones of the attributes, and where the pixels are arranged in each of the discrete rings according to time intervals of the data records. A correlation ring is provided in the graphical visualization in addition to the discrete rings, where the correlation ring has visual indicators for indicating degrees of correlation between at least two of the attributes.

There is provided a method (200) for querying a data stream. The method includes receiving a query plan based on a query specifying the data stream and a window. The method (200) further includes receiving one or more stream elements from the data stream during the window. Additionally, the method (200) includes applying the query to the one or more stream elements by passing the one or more stream elements from a scan operator at a leaf of the query plan to an upper layer of the query plan on a tuple-by-tuple basis. The method (200) also includes committing a result of the query based on the one or more stream elements.

A sentiment cube system is disclosed. In one example, the system discloses a sentiment storage, including a sentiment cube data structure having a set of cells arranged by a set of dimensions. The system includes a computer programmed with executable instructions which operate a set of modules, wherein the modules comprise: a sentiment storage module which receives sentiment values associated with a set of entity features, and then populates a hierarchy of the cells in the sentiment cube with the sentiment values. A sentiment analysis module effecting a set of operations on the sentiment cube.

Systems and methods of data staging for results of analytics are disclosed. An example of a method includes maintaining current results from the analytics in a first data structure, the first data structure having a label identifying first data structure as a target for queries. The method also includes maintaining prior results from the analytics in at least one other data structure. The method also includes changing the label of the first data structure after a predetermined time. The method also includes assigning the label to one of the other data structures, wherein the label identifies the one of the other data structures as the target for queries.
摘要:
A query engine receives a continuous stream of data and applies a Structured Query Language (SQL) query to the data. The data is processed on a chunk-by-chunk basis with a query rewind mechanism that sustains the SQL query as a single long-standing query that allows a state of the SQL query to be maintained.

The present invention, an object display system, provides a system and method for positioning objects on a viewing area. One embodiment can be viewed as providing a method comprising the steps of specifying a plurality of objects, specifying a plurality of object pairs from the plurality of objects, specifying a potential function for each one of the specified object pairs, specifying a similarity value (s) for each one of the specified object pairs, determining an energy (e) for each one of the potential functions and solving for the minimum total energy (E) of the plurality of potential functions such that a distance (r) between each of the specified object pairs is determined.
摘要:
A method is provided for generating a user-defined function (UDF) on a database engine of a database server. A user-function is sent to the database engine. The user-function includes a relational declaration with application and query logic. When the database engine receives the user-function, the database engine generates a function shell. The UDF processes the relational declaration of the user-defined function. The UDF includes the user-function and the function shell. The function shell returns a final data result of the user-defined function through the shell from the database engine.
