It can be applied across different statistical machine translations and with languages that have complicated morphological paradigms. In our method, we first identify morpho-syntactic word classes to build up our statistical language model. Then, we apply a semantic word clustering algorithm for English. The obtained semantic word classes are projected from the English side to the featured Arabic side. This projection is based on available word alignment provided by the alignment step using GIZA++ tool. Finally, we apply a new process to incorporate semantic classes in order to improve the SMT quality. We show its efficacy on small and larger English to Arabic translation tasks. The experimental results show that introducing morpho-syntactic and semantic word classes achieves 7.7% of relative improvement on the BLEU score.","PeriodicalId":420808,"journal":{"name":"Int. J.

Building a service model is an indispensable part of this approach. The design aims to improve the competitiveness of the enterprise by extracting effective user value, establishing a product service system, satisfying the user's needs, and analysing the method of extracting the shape. In this paper, the researcher first selects the target user, draws the user journey map, analyses the user's psychological activities, and uses the innovative design thinking to extract the user value. Secondly, according to the positive value element, the 'human-object' three-dimensional ecological circle is created, at the same time, using AHP hierarchical analysis software to analyse product modelling and build the product service model. Finally, the reliability of the model construction method was verified by the intelligent air quality monitor product service system, and the requirements to meet the needs of users were met. At the same time, it can also provide certain reference for other product service design, reflecting the market competitive advantage of the product.","PeriodicalId":420808,"journal":{"name":"Int. J.

It is the procedure to construct a collision-free path from specified source to destination point. Earlier, classical techniques were widely implemented to solve path planning problems. Classical techniques are very easy to implement but they are time-consuming and are not effective in case of uncertainties. But meta-heuristic techniques have the ability even to perform in an approximate and uncertain environment. This makes the use of meta-heuristic techniques in a more focused manner for the optimal path planning research. This paper presents the Overview, recent trends and advancement from year 2001 to 2017 in the field of optimal path planning using meta-heuristic techniques. During the study, different meta-heuristic algorithms are analysed and classified into three categories: swarm-based meta-heuristic techniques, other than swarm-based techniques and combinational meta-heuristic techniques. In addition, basic understanding and applicability of specific algorithms for path planning are also discussed along with its strengths and downsides.","PeriodicalId":420808,"journal":{"name":"Int.

In bug triaging process, if the first recommended developer cannot fix a bug, it is tossed to another developer and the tossing process is continued till the bug gets assigned and resolved. Existing approaches to the best of our knowledge have not considered developer's contributions and performance assessment metrics for bug triaging process. In this paper, we proposed a novel and improved two phase bug triager that involves a developer profile creation and assignment phases. In this, developer profile is built by using individual contributions (IC) and performance assessment (PA) metrics. Contribution and performance of a developer in pre-fixed bug reports are analysed to calculate a developer's weighted score. This score indicates the level of expertise to fix and resolve a newly reported bug. This approach is tested on two open source projects - Eclipse and Mozilla. Empirical results show that proposed approach has achieved a significantly higher F-score up to 90% for both projects and has effectively reduced bug tossing length up to 11.8% as compared to existing approaches.","PeriodicalId":420808,"journal":{"name":"Int.

While, boundary of optic disc and cup were segmented in feature extraction step. Finally, a cup-to-disc ratio of an exploited image will compute to assess glaucoma in the image.

In this paper, by employing nonparametric non-Gaussianity (NG) measure, a blind source separation/extraction (BSS/BSE) algorithm is derived to separate or extract statistically dependent source signals from their underdetermined or determined linear mixtures. Firstly, we show that maximisation NG measure can separate/extract statistically weak dependent source signals. Then, the nonparametric NG measure is defined by statistical distances between different cumulative distribution function (CDF) of separated signals, which can be estimated by quantiles and order statistics (OS) using L2 norm efficiently. Finally, the nonparametric NG measure aided algorithm is optimised by a deflation procedure. Simulation results for synthesis and real world data show that the proposed algorithm can extract the desired dependent source signals and yield expected performance.","PeriodicalId":420808,"journal":{"name":"Int.

Software datasets comprise of redundant features that hinder effective application of techniques resulting inappropriate defect prediction. Hence, it requires newer application of nonlinear manifold detection techniques (nonlinear MDTs) that has been examined for accurate prediction of defects at lesser time and cost using different classification techniques. In this work, we analysed and tested the effect of nonlinear MDTs to find out accurate and best classification technique for all datasets. Comparison has been made between the results of without or with nonlinear MDTs and paired two-tailed T-test has been performed for statistical testing and verifying the performance of classifiers using nonlinear MDTs on all datasets.

The fundamental assumption made is that for high speed applications, the requirement for an optimal path is secondary to the requirement for short processing times, provided that a solution, if it exists, is found. The proposed solution is benchmarked against the original A* algorithm and shows a reduction in search space of up to 84% and a reduction in processing time of up to 97%. Results for the trajectory planner are also presented, though no direct comparative evaluation against the original tentacles algorithm was executed. The combined path and trajectory processing time of the proposed solution translates to less than 2 mm of travel distance before a reaction to a change in the environment can be processed.","PeriodicalId":420808,"journal":{"name":"Int.

For that, agent paradigm is very promising in ubiquitous healthcare systems. But, the inherent complexity of information security is bigger because agents are characterised by autonomy, intelligence and not under the control of a single entity. Indeed, the big challenge in agent-based ubiquitous healthcare systems is to assure that emergency workers and doctors can access personal information fast and whenever needed but with high level security. The idea, in this paper, is to lighten agents with simple cryptography concepts while strengthening the surveillance and make it collaborative. Consequently, all agents of the system are concerned by security and collaborate to maintain it. The proposed agents are implemented in JADE-LEAP platform designed for restricted devices.","PeriodicalId":420808,"journal":{"name":"Int. J. Intell. Syst. Technol.
