A system and method for creating and editing graph schema data structures in a collaborative, real time graphical editing environment is disclosed. The system and method further operates to integrate external sources of data as components of the graph schema. The system and method outputs definition files for the graph schema data structure and mapping files that enable the population of a graph database.

The invention is a system for integrating data sets organized in one organization type with data sets organized in a second organization type so that data queries submitted to be processed in the manner of the first organization type can be translated into queries usable by the data set in the second data organization type and the results returned to satisfy the first query.

System for accessing a relational database using semantic queries

This invention is a system for integrating data sets organized in one organization type with data sets organized in a second organization type so that data queries submitted to be processed in the manner of the first organization type can be translated into queries usable by the data set in the second data organization type and the results returned to satisfy the first query.

This invention is a system for integrating relational databases into a semantic web framework utilizing a simple mapping process and the SQL query optimizer present in the SQL database engine.

This system comprises methods that simplify the creation of multidimensional OLAP models from one or more semantically enabled data sources. The system also comprises methods enabling interoperability between existing OLAP end-user interfaces, the system's representation of OLAP and the underlying data sources. This includes web-enabled OLAP interfaces.

A system and method for generating structured data outputs from a semi-structured data source. The steps of this method include generating an example output from an example generator. The example output is generated in response to the acquisition of a sequence of annotated strings. The annotated strings are generated in response to the acquisition and modification of at least one data example and corresponding coarse structure from a predetermined input source. Also, a second sequence of annotated strings is generated from input from a semi-structured data source. Both the example output and second sequence of annotated strings are input to an acquisition engine that implements a grammar layer incorporating a top-down parsing method and a comparison layer. The structured data outputs are generated through the cooperation of the comparison layer and the grammar layer.

A plurality of parallel processing elements are connected in a binary tree configuration, with each processing element except those in the highest and lowest levels being in communication with a single parent processing element as well as first and second (or left and right) child processing elements. Each processing element comprises a processor, a read/write or random access memory, and an input/output (I/O) device. The I/O device provides interfacing between each processing element and its parent and children processing elements so as to provide significant improvements in propagation speeds through the binary tree. The I/O device allows the presently preferred embodiment of the invention to be clocked at 12 megahertz, producing in the case of a tree of 1023 processors, each having an average instruction cycle time of 1.8 .mu.s, a system with a raw computational throughput of approximately 570 million instructions per second. The I/O device communicates data and queries from the root processing element to all other N processing elements in the array in one processor instruction cycle instead of in O(log.sub.2 N) processor instruction cycles as in prior art binary tree arrays. Primitive queries are executed in parallel by each processing element and the results made available for reporting back to the root processing element. In several important cases, these results can be combined and reported back to the root processing element in a single processor instruction cycle instead of in O(log.sub.2 N) processor instruction cycles as in prior art binary tree arrays. Thus, the elapsed time for a broadcast and report operation is in effect a constant time regardless of the number of processors in the array.
