The semantics of Chemical Markup Language (CML) for computational chemistry : CompChem

open access: yesJournal of Cheminformatics, 2012
This paper introduces a subdomain chemistry format for storing computational chemistry data called CompChem. It has been developed based on the design, concepts and methodologies of Chemical Markup Language (CML) by adding computational chemistry ...

Combining link and content-based information in a Bayesian inference model for entity search

open access: yes, 2012
An architectural model of a Bayesian inference network to support entity search in semantic knowledge bases is presented. The model supports the explicit combination of primitive data type and object-level semantics under a single computational framework.

Adjunctions for exceptions

open access: yes, 2012
An algebraic method is used to study the semantics of exceptions in computer languages. The exceptions form a computational effect, in the sense that there is an apparent mismatch between the syntax of exceptions and their intended semantics.

Indistinguishability in controlled query evaluation over prioritized description logic ontologies

open access: yesWeb Semantics
In this paper we study Controlled Query Evaluation (CQE), a declarative approach to privacy-preserving query answering over databases, knowledge bases, and ontologies. CQE is based on the notion of censor, which defines the answers to each query posed to

Fast Search Using k-d Trees with Fine Search for Spectral Data Identification

open access: yesMathematics
Spectral identification is an essential technology in various spectroscopic applications, often requiring large spectral databases. However, the reliance on large databases significantly increases computational complexity.

Semantics representation in a sentence with concept relational model (CRM) [PDF]

open access: yes, 2009
The current way of representing semantics or meaning in a sentence is by using the conceptual graphs. Conceptual graphs define concepts and conceptual relations loosely.
