A Simple Context Dependent Suggestion System

Dwaipayan Roy, Ayan Bandyopadhyay, Mandar Mitra
2013 Text Retrieval Conference  
In this paper, we present our approach to providing user and context dependent suggestions.  ...  The Contextual Suggestion Problem focuses on search techniques for complex information needs that are highly dependent on context and user interest.  ...  A system is expected to return a ranked list of at least 50 suggestions for each given user-context pair.  ...

Empirical Study of KMS Impact on Decision Support

Kursad OZLEN, Meliha HANDZIC, Nermina DURMIC
2014 Eurasian Journal of Business and Economics  
In contrast, greater KMS sophistication made no difference to system usage behaviour and decision performance in complex contexts.  ...  The results indicate that the positive impact of KMS sophistication was limited to simple decision contexts only.  ...  Finally, given the contradictory and limited nature of current findings Table 1 : 1 Descriptive results for system use variables by context and KMS Dependent Simple Context Complex Context Variable  ...

Orienting the Interaction Compass: Resource Availability as a Major Driver of Context Dependence

Elizabeth G. Pringle
2016 PLoS Biology  
Their results suggest that a complex continuum of interaction outcomes can result from the simple combined effects of nutrient availability and density-dependent population dynamics.  ...  Using a simple laboratory system, Hoek and colleagues present evidence that resource availability can be a primary driver of variation between interactions.  ...  Work on positive interactions between plants had in fact previously suggested a general "stress gradient hypothesis" for predicting these context-dependent outcomes: interactions should transition from  ...

On the context-dependent scaling of consumer feeding rates

Daniel Barrios-O'Neill, Ruth Kelly, Jaimie T. A. Dick, Anthony Ricciardi, Hugh J. MacIsaac, Mark C. Emmerson, Greg Grether
2016 Ecology Letters  
The stability of consumer-resource systems can depend on the form of feeding interactions (i.e. functional responses).  ...  However, little is known about how interaction contexts (e.g. simple or complex habitats) might alter scaling relationships.  ...  We envisage a Context-Dependent Scaling (CDS) of feeding rates as consumer-resource systems move between contexts that systematically modify a consumer's search space and encounter rate with resources.  ...

A latent attractors model of context selection in the dentate gyrus–hilus system

Simona Doboli, Ali A. Minai, Phillip J. Best
1999 Neurocomputing  
In this paper, we speculate that the dentate gyrus}hilus (DGH) system, with its disynaptic recurrent connectivity plays a central role in creating context-dependent place representations.  ...  The origin of this context dependence is not known.  ...  Theoretical model Context dependence in place "elds suggests the existence of a multi-stable attractor-based context system in the hippocampus.  ...

Contexts, Domains, and Software [chapter]

Alfs Berztiss
1999 Lecture Notes in Computer Science  
We survey some issues that relate to context dependence and context sensitivity in the development of software, particularly in relation to information systems by defining a range of context-related concepts  ...  Domain models are identified as the appropriate framework for dealing with context-related issues.  ...  This two-way split suggests a partitioning of contexts into internal and external. The term internal context relates to cases in which the actions of a software system depend on internal factors.  ...

A Context Space Model for Detecting Anomalous Behaviour in Video Surveillance

Arnold Wiliem, Vamsi Madasu, Wageeh Boles, Prasad Yarlagadda
2012 2012 Ninth International Conference on Information Technology - New Generations  
A comparative analysis is conducted between a context-based system which employs the proposed context space model and a system which is implemented based on one of the existing approaches.  ...  This paper proposes a context space model which has two benefits: (a) It provides guidelines for the system designers to select information which can be used to describe context; (b) It enables a system  ...  A. Scenario description We created a simple scenario from the video clips provided in CAVIAR dataset 1 for outlining the advantage of the context-based system over the existing system.  ...

Exploring location-dependency in process modeling

Xinwei Zhu, Jan Recker, Guobin Zhu, Flávia Maria Santoro
2014 Business Process Management Journal  
Findings -This paper introduces location-awareness as a new perspective to extend context-awareness in BPM research, by introducing relevant location concepts such as location-awareness and location-dependencies  ...  Design/methodology/approach -This paper uses a pattern-based approach to identify location-dependency in process models. We design specifications for these patterns.  ...  We regard our paper as a conceptual starting point for further exploration of the concept of location dependency in the management of business processes, as well as the related challenges.  ...

Interactions between the hippocampus, prefrontal cortex, and amygdala support complex learning and memory

Ersin Yavas, Sarah Gonzalez, Michael S. Fanselow
2019 F1000Research  
In most situations, memory requires interactions between these circuits and they can act in a facilitative manner to generate adaptive behavior.  ...  One of the guiding principles of memory research in the preceding decades is multiple memory systems theory, which links specific task demands to specific anatomical structures and circuits that are thought  ...  Contexts are complex stimuli made of many features, all of which may lack the salience of the sudden onset of a simple auditory stimulus such as a tone 8 .  ...

Aspect-driven Context-aware Services

Karel Cemus, Filip Klimes, Tomas Cerny
2017 Proceedings of the 2017 Federated Conference on Computer Science and Information Systems  
Such architecture involves adaptive, context-aware services preserving simple maintenance while addressing information reuse and crosscuts across services.  ...  Nowadays enterprise software solutions must deal with ever-growing complexity and a multitude of business processes. The mainstream system design decomposes the system into small reusable services.  ...  However, the approach itself is general and there are more evolved specializations such as Microservices pattern [9] . 2 Microservices pattern suggests a use of a simple connection and smart endpoints  ...

In this paper, we demonstrate our query suggestion system called CONQUER, which allows to efficiently suggest queries for a given partial query and a number of available query context observations.  ...  The context-awareness allows for suggesting queries tailored to a given context, e.g., the user location or the time of day.  ...  DEMONSTRATION Explore Context Dependency The GUI allows to change the values of the context parameters on the fly so that the context dependency of the suggestion can be explored dynamically.  ...

SemEval-2012 Task 1: English Lexical Simplification

Lucia Specia, Sujay Kumar Jauhar, Rada Mihalcea
2012 International Workshop on Semantic Evaluation  
The task requires that annotators and systems rank a number of alternative substitutes -all deemed adequatefor a target word in context, according to how "simple" these substitutes are.  ...  This is the first time such a shared task has been organized and its goal is to provide a framework for the evaluation of systems for lexical simplification and foster research on context-aware lexical  ...  The best systems on the shared task were those that relied on this association, and integrated both context-dependent and context-independent features.  ...
