Role-based access control (RBAC) and attribute-based access control (ABAC) are currently the most prominent access control models. However, they both suffer from limitations and have features complimentary to each other. Due to this fact, integration of RBAC and ABAC has become a hot area of research recently. We propose an access control model that combines the two models in a novel way in ord...

Instrumentation to automatically log information – so called gameplay metrics – about the player-game interaction has become an important tool for analyzing player behavior in games. However, due to the usually large amount of gathered data, analysis of the collected data can be challenging. Visualizations have become a promising addition to statistical techniques to explore and better understa...

We present a novel technique for semantic frame identification using distributed representations of predicates and their syntactic context; this technique leverages automatic syntactic parses and a generic set of word embeddings. Given labeled data annotated with frame-semantic parses, we learn a model that projects the set of word representations for the syntactic context around a predicate to...

The numerical dissipation operator of residual-based compact (RBC) schemes of high accuracy is identified and analysed for hyperbolic systems of conservation laws. A necessary and sufficient condition (v-criterion) is found that ensures dissipation in 2-D and 3-D for any order of the RBC scheme. Numerical applications of RBC schemes of order 3, 5 and 7 to a diagonal wave advection and to a conv...

This paper examines the relationship between two important arguments in core cosubordinate construction in Filipino: namely, controller found in the matrix core and the missing argument (controllee) in the linked core using the framework Role and Reference Grammar of Van Valin (2005). This paper has proved that there is really an argument sharing between two cores and each core plays a crucial ...

Semantic Role Labeling (SRL) is an important task since it benefits a wide range of natural language processing applications. Given a sentence, the task of SRL is to identify arguments for a predicate (target verb or noun) and assign semantically meaningful labels to them. Dependency parsing based methods have achieved much success in SRL. However, due to errors in dependency parsing, there rem...

In this study, Science Applications International Corporation (SAIC) and Georgia Institute of Technology (GT) developed a quantitative-qualitative mixed methods research technique to investigate the extent to which real world characteristics of Massively Multiplayer Online Role-Playing Game (MMORPG) players can be predicted based on the characteristics and behavior of their avatars. SAIC used t...

Among access control models, Role-Based Access Control (RBAC) is very useful and is used in many computer systems. Static Combination of Duty (SCD) and Dynamic Combination of Duty (DCD) constraints have been introduced recently for this model to handle dependent roles. These roles must be used together and can be considered as a contrary point of conflicting roles. In this paper, we propose sev...

When training semantic role labeling systems, the syntax of example sentences is of particular importance. Unfortunately, for the FrameNet annotated sentences, there is no standard parsed version. The integration of the automatic parse of an annotated sentence with its semantic annotation, while conceptually straightforward, is complex in practice. We present a standard dataset that is publicly...

We propose a preliminary study for the application of Computational Linguistics techniques such as the Semantic Role Labeling of natural languages (SRL) to the case of sketch understanding. The idea of our approach originates from a psychological experiment where two groups of students were asked to produce and then recognize hand-drawn sketches, respectively. The paper presents a procedure to ...
