Cognitive agents are typically utilized in autonomous systems for automated decision making. These systems interact at real time with their environment and are generally heavily power constrained. Thus, there is a strong need for a real time agent running on a low power platform. This paper examines how some of the components of a cognitive agent can be mapped onto lookup tables stored in memristor...
The paper describes building systems for computational linguistics based on an approach to the image text comprehension. There had been suggested a set theoretical formalization for such type of systems using the fuzzy sense relationship. The possibilities of conceptual approach had been demonstrated on the solution examples of such tasks as searching for reference words, building lexical ontology...
Geovideo is a sort of video data with spatial reference, an organism composed of video data and geographic space. It covers different kinds of information, such like images, sounds, positions and space-time information, which are all in the united georeferenced. This kind of video data can be obtained from monitoring system and other video with georeference. Obviously, Geovideo is applicable to public...
This paper describes a new heuristic approach letting an agent in a multi-agent system make a decision for selecting tasks to undertake. The proposed approach consists in giving the agent a profile including preferences and physical parameters, and a description of its beliefs about the environment. The decision engine allowing the agent to do a specific task is local to the agent and takes into account...
Text Generation is a challenging task in Natural Language Processing (NLP). Its purpose is to generate grammatically correct text from machine representation source such as a knowledge base. One of the most recent semantic representation is Rich Semantic Graph (RSG). It exploits not only the semantic representation techniques but also the Language structure and writing styles. Our work is a part of...
Mathematical and uncertainty modelling is an important component of data fusion (the fusion of unprocessed sensor data) and information fusion (the fusion of processed or interpreted data). If uncertainties in the modelling process are not or are incorrectly accounted for, fusion processes may provide under- or overconfident results, or in some cases incorrect results. These are often owing to incorrect...
In this paper, we represent the context based weighting scheme for vector space model to evaluate the relation between concept and context in Information storage and retrieval system. A meaning of a word is relatively decided by a context dynamically. A vector space model, generally use a static weighting scheme for term document matrix like latent semantic indexing (LSI), co-occurrence or correlations...
MOOCs (Massive Open Online Courses), a new form of learning, are characterized by a large scale of subscription. Thus, appropriate assessment strategies should be implemented to support massive data flows. In this paper, we are interested in studying the Peer Assessment in MOOCs based on Inquiry Based Learning (IBL), iMOOCs. Our contribution is a continuation of our previous research work. In fact,...
In this paper, we show how computational methods can help attaining uniformity in interpretation, a valuable asset in the legal field, and even a duty itself in our use case of choice: the 1980 Vienna Sales Convention (CISG). We investigate the common ground between traditional and computational models and describe some tools for the representation and interpretation of the CISG terminology that can...
Ontology Based DataBase (OBDB) is a database model that allows both ontologies, which is a formal representation of terms related to specific domain, and their instances to be stored and queried in a single database. In this paper, we propose the construction of OBDB for the development of medical system. The idea is to automatically construct OBDB using rules and used it in the construct of medical...
Example tracing tutors has proven to be one of the simplest methods for modelling domain limited scenarios within intelligent tutoring systems [1]. The intelligence embedded within this type of tutors lies in the feedback it possesses during creation and how it is triggered based on learner interaction with the example. Since real-life tutoring in 1-to-1 scenarios proves to have the ultimate learning...
This paper presents the composition model of semantically oriented technologies and SOA. The design of the service interface allows machine machine communication, which enables an automated access to and use of the government administration public services. The creation of knowledge ontology on a unique web location eases the user's search for a service. The solutions are implemented by the combination...
Due to the fact that most of current E-learning systems have problems of insufficient personalization, this paper puts forward the idea that completes the personalized knowledge search based on the open source E-learning system, then constructs domain ontology that are used to build user interest model, and finally, this model is embedded in Notch search engine to realize the personalized knowledge...
SmartRoom is a system supporting collaboration activities localized in a room: a set of digital services is available for organizers and participants. The Smart-M3 platform is used to set up a networked knowledge sharing environment on top of which the SmartRoom service set is deployed. In this paper we introduce the methodology and design of the SmartRoom system. We consider realization of digital...
In this paper, the representation method of user interest model is a combination of vector space model with Ontology. It introduces the algorithm of semantic similarity when calculating the term weight, and considers the semantic similarity of words, and then the term weight is updated through the Bayesian network. This paper focuses on the steps of building and updating the user interest model, and...
The Reference Model for an Open Archival Information System has been extraordinarily influential within the digital preservation community. The Preserving Virtual Worlds project explored the application of the OAIS Reference Model for the preservation of computer games, videogames and electronic literature within a research library setting. This paper identifies practical problems in determining the...
Computer games is a form of real-time interactive software wrapped in creatively crafted media that offers game-players engaging, goal-directed play. Designing computer games requires adequate experience and great attention to detail to describe the rules, play and aesthetics that compose the interactive experience. For inexperienced game designers, formalised methods such as game design languages...
Analyze the cases that concepts in ontology are similar, establish a concept similarity computation model based on domain ontology; The computation of concept similarity not only considers the semantic distance between concepts, but also considers the conceptual layer factor and superior concepts coincidence degree, quantizing semantic similarity between concepts nodes in ontology network more comprehensively;...
High-Definition Environmental-Protection Multimedia Intelligent Conference System is aiming at innovation and integration innovation. It is realized to control of network and integration from basic control to information display though the optical-transmission technology. Electronic meeting systems, high definition camera system, high definition display systems, video attendance-register meeting system,...
In order to lighten the burden of worknet and shorten the respond time of ISMBDI mode, a cache mechanism for ISMBDI mode is built, and correspondingly a new cache replacement policy LRAFU is presented. This policy well integrates the traditional cache replacement policies LRU (Least Recently Used) and LFU (Least Frequently Used), not only avoids the problem of cache pollution, fits the character of...
