Information Extraction as a Stepping Stone toward Story Understanding

Historically, story understanding systems have depended on a great deal of hand-crafted knowledge. Natural language understanding systems that use conceptual knowledge structures [Schank and Abelson, 1977; Cullingford, 1978; Wilensky, 1978; Carbonell, 1979; Lehnert, 1981; Kolodner, 1983] typically rely on enormous amounts of manual knowledge engineering. While much of the work on conceptual kno...

Intelligent Network-Based Stepping Stone Detection Approach

This research intends to introduce a new usage of Artificial Intelligent (AI) approaches in Stepping Stone Detection (SSD) fields of research. By using Self-Organizing Map (SOM) approaches as the engine, through the experiment, it is shown that SOM has the capability to detect the number of connection chains that involved in a stepping stones. Realizing that by counting the number of connection...

Sensitivity of Perfect and Stone-Wales Defective BNNTs Toward NO Molecule: A DFT/M06-2X Approach

The monitoring and controlling of environmental pollutions are very important in biological and industrial processes, and a great interest is growing with the development of suitable gas–sensitive materials and hazardous chemical removal devices. In this work, the highly parameterized, empirical exchange–correlation functional M06–2X were employed to investigate the electronic sensitivity of pe...
