This paper describes an application for computing first-order semantic representations of English texts. It is based on a combination of hybrid shallow-deep components arranged within the middleware framework Heart of Gold. The shallow-deep semantic analysis employs Robust Minimal Recursion Semantics (RMRS) as a common semantic underspecification formalism for natural language processing components...
The acquisition of knowledge is an important factor for enterprises to stay in competition. In this context, especially the integration of structured and unstructured data is a vital task and has been subject to research for many years. Opposed to other integration strategies, we propose an architecture that relies on first-order logic as a semantical foundation. Using a controlled natural language,...
This paper provides a novel framework for semantic representation of Chinese news based on conceptual network which is described hierarchically in three layers. we first define the structure of independent concept that is the basic element of the framework. Then the domain specific semantic unit called knowledge node is illustrated. Finally, the knowledge tree which gives a well formed semantic hierarchy...
