A method and a system process a stream of data in parallel across a plurality of nodes. The log processing system has a log module, a query language module, and a query processing module. The log module receives and organizes the stream of data into a sequential and nested data structure. The query language operator module defines operators that operate on the sequential and nested data structure. The query processing module processes in parallel across a plurality of nodes a query based on an operator on the stream of data.

Parallel data stream processing system

There is provided a method and system for qualification testing in a social network service. Qualification testing provides access control into a social network, wherein qualification is based on answers to questions related to a topic. In one example, members admitted to the network provide guidance, notes and research assistance to another member. The social network members access the social network from an external networked computing service, such as another social network, to facilitate easy connection to potential members. The social network may be implemented as an application overlay to the external service, or may access connections in the external network.

Method and apparatus for social network qualification systems

A method and system for forming hybrid cluster to process log files are described. In example embodiments, a method configures a node to execute as a first slave node. The first slave node executes in a first operating environment. The method also adds the first slave node to a Hadoop cluster. The Hadoop cluster includes a second slave node that operates in a second and different operating environment.

Distributed steam processing

A method and system analyze data associated with a marketplace category. In some embodiments, a query is received that identifies a marketplace category from multiple marketplace categories associated with an electronic commerce marketplace. Data associated with the marketplace category is accessed and analyzed to identify multiple keywords used to identify listings in the marketplace category. A user interface is generated to display the analysis results, including at least a portion of the multiple keywords used to identify listings in the marketplace category.

Category management and analysis

Distributed stream processing

In various exemplary embodiments, a system and method is disclosed to analyze event streams of a user session. One embodiment of the method includes logging a plurality of events from an event stream, specifying conditions to sort the plurality of events, applying the conditions to the plurality of events, producing a probability distribution of event nodes after a given node in the event stream, and producing an interactive graphical reduction of a produced graph by determining patterns in a graphical tree and unifying occurrences of the patterns.
