Context-Specific grounding of web natural descriptions to human-centered situations

作者:

Highlights:

• This novel W2S method is effective in grounding web natural descriptions into human-centered situations. With the grounded knowledge, human-centered situations could be effectively understood.

• The influence of environmental context towards humans’ activities could be measured. The context involvements in situation representation could improve the accuracy of situation understanding.

• The proposed semantic analysis method could evaluate the situation-involvement degree of the knowledge entities (i.e., objects and environmental context) and their relations. Based on the involvement degree, the key features including objects, environmental context, and their mutual relations could be extracted to accurately represent a situation.
