Use of c-contexts to capture extra information not represented in underlying schemas, and the use of inference operations to reason about information content. 1.

متن کاملFrom Data to Semantic Information
There is no consensus yet on the definition of semantic information. This paper contributes to the current debate by criticising and revising the Standard Definition of semantic Information (SDI) as meaningful data, in favour of the Dretske-Grice approach: meaningful and well-formed data constitute semantic information only if they also qualify as contingently truthful. After a brief introducti...

متن کاملFrom Metadata to Fuzzy Knowledge Representation
Abstract: In this paper we present an approach to organize Web-accessible courseware according to knowledge domains, by means of fuzzy clustering. A new modified version of the Fuzzy C-Means clustering algorithm that employs a non-Euclidean metric is proposed and some preliminary trials with the new metric are presented. The experimental results show that the modified algorithm performs better ...
متن کاملFrom Surface Dependencies towards Deeper Semantic Representations
In the past, a divide could be seen between ’deep’ parsers on the one hand, which construct a semantic representation out of their input, but usually have significant coverage problems, and more robust parsers on the other hand, which are usually based on a (statistical) model derived from a treebank and have larger coverage, but leave the problem of semantic interpretation to the user. More re...
