ViSPE: A Graphical Policy Editor for XACML
2015
In this paper we present the Visual Security Policy Editor (ViSPE), a policy-maker-friendly graphical editor for the eXtensible Access Control Markup Language (XACML). The editor is based on the programming language Scratch and implemented in Smalltalk. It uses a graphical block-based syntax for declaring access control polices that simplifies many of the cumbersome and verbose parts of XACML. Using a graphical language allows the editor to aid the policy-maker in building polices by providing visual feedback and by grouping blocks and operators that fit together and also indicating which blocks that stick together. It simplifies building policies while still maintaining the basic structure…
What Makes a Text Easy or Difficult to Understand?
1989
Abstract The question of what makes a text easy or difficult to comprehend is answered on the basis of an empirical investigation, which draws especially on theories related to text and memory linguistics. Easy and difficult texts, verified empirically, were analyzed on micro‐ and macro‐levels. Certain aspects of syntax, lexicon and information structure were first studied. These were followed by text‐level analyses related to the narrative and structural organization and the propositional structure of the texts. The article gives an account of the parameters that were most clearly associated with level of text comprehension. The results are also discussed in the light of the possible impli…
Case assignment, case concord, and quantificational case constructions
2011
Abstract This paper examines a controversial and particularly complex case phenomenon called quantificational case attested in a number of historically unrelated Slavonic and Finno-Ugric languages, and attempts to establish certain novel cross-linguistic generalizations and conclusions. In particular, it will be argued that (i) instead of standard one-to-one case assignment, in which one case assigner is case-related to one case assignee, a many-to-many case flow is attested; (ii) nominal case is not a privilege of full DPs, arguments or thematic roles; (iii) case reflects either local or nonlocal functional structure, whether in the verbal or nominal domain; and that (iv) there is no disti…
The influence of task-irrelevant music on language processing: syntactic and semantic structures.
2011
Recent research has suggested that music and language processing share neural resources, leading to new hypotheses about interference in the simultaneous processing of these two structures. The present study investigated the effect of a musical chord's tonal function on syntactic processing (Experiment 1) and semantic processing (Experiment 2) using a cross-modal paradigm and controlling for acoustic differences. Participants read sentences and performed a lexical decision task on the last word, which was, syntactically or semantically, expected or unexpected. The simultaneously presented (task-irrelevant) musical sequences ended on either an expected tonic or a less-expected subdominant ch…
The Regularity of Rhythmic Primes Influences Syntax Processing in Adults
2019
Recent research has shown that auditory rhythmic stimulation improves subsequent syntax processing of speech in children with and without developmental language disorders. Sensitivity to grammatica...
Extensible Visualizations of Ontologies in OWLGrEd
2019
OWLGrEd is a visual editor for OWL 2.0 ontologies that combines UML class diagram notation and textual OWL Manchester syntax for expressions. We review the basic OWLGrEd options for ontology presentation customization and consider the framework of OWLGrEd extensions that enables introducing rich use-case specific functionality to the editor. A number of available OWLGrEd extensions offering rich ontology management features to their end-users are described, as well.
A Hidden Markov Model for Automatic Generation of ER Diagrams from OWL Ontology
2014
Connecting ontological representations and data models is a crucial need in enterprise knowledge management, above all in the case of federated enterprises where corporate ontologies are used to share information coming from different databases. OWL to ERD transformations are a challenging research field in this scenario, due to the loss of expressiveness arising when OWL axioms have to be represented using ERD notation. In this paper we propose an innovative technique for estimating the most likely composition of ERD constructs that correspond to a given sequence of OWL axioms. We model such a process using a Hidden Markov Model (HMM) where the OWL inputs are the observable states, while E…
MetaEdit— A flexible graphical environment for methodology modelling
1991
Existing CASE tools are often rigid and do not support the users' native methodologies. To alleviate this, more flexible and customisable tools called CASE shells are emerging. However, the customisation of those tools is still cumbersome and error-prone, and demands several configuration files that follow a rigid syntax of some metamodelling language(s). In order to make the customisation easier, we propose a graphical metamodelling editor, MetaEdit, with which the conceptual structures of the user methodology can be modelled easily using an easy-to-grasp graphical notation. With MetaEdit, methodology models can be constructed with less effort and the configuration files for the CASE shell…
From sentence production to text production: Investigating fundamental processes
1991
The purpose of the present article is to present a nom exhaustive review about the cognitive psychology research in english and in french language, dealing with the study of the organization and the functioning of the oral and written language production mechanisms.
SEAL: A Domain-Specific Language for Novice Wireless Sensor Network Programmers
2013
A lot of the prospective wireless sensor network users are novice programmers. Their experience in general-purpose programming languages is either limited or completely nonexistent. There are both financial and scientific incentives to empower these users and allow them to write sensor network applications on their own, rather than having to rely on a qualified computer science professional. We present SEAL, a sensor network programming language designed for novice programmers. SEAL manages to avoid computer science concepts that are hard to grasp for novices, while remaining suitable for typical sensor network application scenarios. The language is extensible in application-specific way, h…
