With the advent of Semantic Web, knowledge-based interoperability faces a new technological shift, in which ontologies and semantic web technologies play a major role. Exploiting the explicit semantic description of the domain of discourse allows reasoning and automatically acquiring semantic relations between two different domains of discourses. Such semantic relations would be further applied...

With the expanding of the Semantic Web and the availability of numerous ontologies which provide domain background knowledge and semantic descriptors to the data, the amount of semantic data is rapidly growing. The data mining community is faced with a paradigm shift: instead of mining the abundance of empirical data supported by the background knowledge, the new challenge is to mine the abunda...

Computational Narrative has provided several examples of how to process narrations using semantical approaches. While many useful concepts for computational management of stories have been unveiled, a common barrier has hindered their development: semantic knowledge is still too complex to handle. In this paper, a focus shift based on narrative structure is proposed. Instead of digging deeper i...

The paper offers a new type of approach to the semantic phenomenon of adverbial aspect shift within the framework of finitestate temporal semantics. The heart of the proposal is a supervaluational concept of underspecification, and the idea of treating the meanings of temporal prepositions as dynamic presuppositions. The simple shifting algorithm used in the present approach derives the correct...

We present a shift-reduce rhetorical parsing algorithm that learns to construct rhetorical structures of texts from a corpus of discourse-parse action sequences. The algorithm exploits robust lexical, syntactic, and semantic knowledge sources.

Among Quine’s main concerns in his “On What There Is”, there was that of solving a problem of expressibility for ontological denials. His proposed solution to such a problem was, in a purely Carnapian vein, a shift of attention to the semantic features of ontological claims – what Quine called the strategy of “semantic ascent”. Quine’s relevant assumption is that talk about language is much les...

We discuss novel data involving attitude predicates in American Sign Language. We offer evidence against the uniform treatment of attitudes by revealing new structural and interpretive differences between proffering and doxastic embedding predicates. Besides providing evidence for this distinction from a new domain, the data also advance the current understanding of the formal syntactic/semanti...

Several semantic based user profile approaches have been introduced in the literature to learn the users’ interests for personalized search. However, many of them are ill-suited to cope with a domain of information that evolves and user interests that may change over time. In this paper, we propose a novel dual representation of a user’s semantic profile to deal with this problem: (1) a lower-l...
