Distributional semantic models are strongly dependent on the size and the quality of the reference corpora, which embeds the commonsense knowledge necessary to build comprehensive models. While high-quality texts containing large-scale commonsense information are present in English, such as Wikipedia, other languages may lack sufficient textual support to build distributional models. This paper proposes using the combination of a lightweight (sloppy) machine translation model and an English Distributional Semantic Model (DSM) to provide higher quality word vectors for languages other than English. Results show that the lightweight MT model introduces significant improvements when compared to language-specific distributional models. Additionally, the lightweight MT outperforms more complex MT methods for the task of word-pair translation.

Different semantic interpretation tasks such as text entailment and question answering require the classification of semantic relations between terms or entities within text. However, in most cases, it is not possible to assign a direct semantic relation between entities/terms. This paper proposes an approach for composite semantic relation classification using one or more relations between entities/term mentions, extending the traditional semantic relation classification task. The proposed model is different from existing approaches which typically use machine learning models built over lexical and distributional word vector features in that is uses a combination of a large commonsense knowledge base of binary relations, a distributional navigational algorithm and sequence classification to provide a solution for the composite semantic relation classification problem. The proposed approach outperformed existing baselines with regard to F1-score, Accuracy, Precision and Recall.

This paper provides a comparative analysis of the performance of four state-of-the-art distributional semantic models DSMs over 11 languages, contrasting the native language-specific models with the use of machine translation over English-based DSMs. The experimental results show that there is a significant improvement average of 16.7i¾?% for the Spearman correlation by using state-of-the-art machine translation approaches. The results also show that the benefit of using the most informative corpus outweighs the possible errors introduced by the machine translation. For all languages, the combination of machine translation over the Word2Vec English distributional model provided the best results consistently average Spearman correlation of0.68.

Investigation of the chaotic behavior of traffic streams at urban intersections due to signals has involved researchers in endeavoring to predict a smooth traffic flow model for stabilizing traffic congestion and avoid unnecessary delays. In this paper, we study a hybrid adaptive model, based on a combination of coloured Petri nets, fuzzy logic and learning automata, to efficiently control traffic signals. We show that in comparison with results found in the literature, vehicle delay time is significantly reduced using the proposed method.

In this paper, a technical approach to particle swarm optimization method is presented. The main idea of the paper is based on local extremum escape. A new definition has been called the worst position. With this definition, convergence and trapping in extremumlocal be prevented and more space will be searched. In many cases of optimization problems, we do not know the range that answer is that.In the results of examine on the benchmark functions have been observed that when initialization is not in the range of the answer, the other known methods are trapped in local extremum. The method presented is capable of running through it and the results have been achieved with higher accuracy. DOI: http://dx.doi.org/10.11591/ij-ai.v1i1.367

Increasing number of vehicles, as the natural consequence of population growth, has caused a significant bottle-neck in transportation network and consequently major delays at intersections. Hence, in this paper we study a hybrid adaptive model, based on combination of Coloured Petri Nets, Fuzzy Logic and Learning Automata to efficiently control traffic signals. We show that in comparison with the results found in the literature the vehicle delay time is drastically reduced using the proposed method.

In this article an algorithm is presented for edges coloring of the graph. In this algorithm the node that we discuss represented by an Agent and then all the nodes of a graph like multi-agent system. Each node independently colours its edges with respect to cellular automata using distributed and paralleling of the process. Innovation of this method is on distributing of the process for each node so that each node updates its edges color only with the use of its neighbors in some steps until all graphs are colored completely. At the end the results are being tested on some Standard graphs and the results are presented. In this method, each graph is colored using one rule repetition for each node with high speed on its edges.

Designing user interface has special importance in Virtual Learning. Considerable portion of students' time is spent in attempting to learn system, work with present lists in user interface and so forth. Perhaps virtual education system has several computational powers, but it lacks adequate user interface. Then, using system would be difficult and user may encounter many confuses during the work and would be unsuccessful in reaching their goals. These are results of unfamiliarity with fundamental principles and in user interface design and disusing them in generating virtual learning systems. Thus, in any virtual learning system design, it is necessary to consider fundamental principles and rules of the user interface design in such system, and in this manner, in this research an adequate user interface is suggested for e-learning Environment in which has been evaluated with regard to these fundamental principles and rules. Evaluations have been done on this interface show its desirable ability to attract users' satisfaction.
