We review lexical Association Measures (AMs) that have been employed by past work in extracting multiword expressions. Our work contributes to the understanding of these AMs by categorizing them into two groups and suggesting the use of rank equivalence to group AMs with the same ranking performance. We also examine how existing AMs can be adapted to better rank English verb particle constructions and light verb constructions. Specifically, we suggest normalizing (Pointwise) Mutual Information and using marginal frequencies to construct penalization terms. We empirically validate the effectiveness of these modified AMs in detection tasks in English, performed on the Penn Treebank, which shows significant improvement over the original AMs. © 2009 ACL and AFNLP

The availability of large historical corpora, such as Google Books Ngram, makes it possible to extract various meta information about the evolution of human languages. Together with advances in machine learning techniques, researchers recently use the huge corpora to track cultural and linguistic shifts in words and terms over time. In this paper, we develop a new approach to quantitatively recognize semantic changes of words during the period between 1800 and 1990. We use the state-of-the-art FastText approach to construct word embedding for Google Books Ngram corpus for the decades within the time period 1800-1990. We use a time series analysis to identify words that have a statistically significant change in the period between 1900 and 1990. We conduct a performance evaluation study to compare our approach against related work, we show that our system is more robust against morphological language variations.

The emerging trend of distributed and renewable energy sources encourages energy trading in the electricity market. Various forms of energy markets are evolving for successful energy trading. The local energy market is one of them in which various participants are actively coordinating for optimal utilization of power. Such type of local energy markets provides individual prosumers to trade their surplus energy in the neighbourhood in peer-to-peer topology. The complexity of such type of local energy market is increasing in terms of structure, control, coordination, and cost estimation. For the cooperative behaviour of the local energy markets, a dual auction coordination control scheme is important to encourage more prosumers for energy trading. We proposed a novel scheme that performs dual auctions for prosumers in a decentralized fashion. We assessed dual auction matching by coordinating prosumers and consumers to sell and purchase energy in the local energy market. The aggregator performed balancing in the proposed dual auction scheme as an autonomous entity. The results were simulated in MATLAB and JADE for the complex prosumer peer-to-peer network. Our proposed scheme shows each peer dual auction matching improves from 0.95 to 2.03 for optimal hierarchal energy trading in energy markets. For peer participation, the participation ratio increased from 0.684 to 1.74 and optimal aggregator coordination from 9.18% to 19% in the local energy markets. © 2023 IEEE.

This paper contributes to solve effectively stochastic resource allocation problems known to be NP-Complete. To address this complex resource management problem, previous works on pruning the action space of real-time heuristic search is extended. The pruning is accomplished by using upper and lower bounds on the value function. This way, if an action in a state has its upper bound lower than the lower bound on the value of this state, this action may be pruned in the set of possible optimal actions for the state. This paper extends this previous work by proposing tight bounds for problems where tasks have to be accomplished using limited resources. The marginal revenue bound proposed in this paper compares favorably with another approach which proposes bounds for pruning the action space.

Web extension is a software that can be installed on a web browser. A web-extension link is displayed as an icon on the toolbar of the browser. Based on browsing activity, the extension works automatically or by clicking the extension icon depending on the functionalities made in the extension software. In this work, we developed a web extension on Google Chrome browser to verify online texts by simply clicking on an extension button. Upon clicking the button, the underlying algorithm in the extension software retrieves the texts from the current web-page being displayed. Verification and authentication of texts are performed by comparing the retrieved texts with text database. According to the comparison, texts are highlighted in colors. We consider authentication of Arabic Hadith texts for a case study. The authentic Hadith texts are highlighted by green color;authentic texts with partial diacritics, by yellow;and unauthentic texts, by red. This technique can also be used to authenticate laws, constitutions and Government documents in any language. © 2019 IEEE.

software development involves a significant amount of team effort where collaboration and communication of the team members are crucial. The team meetings are core activities in all stages of the software development process. Even though these meetings often are conducted face-to-face (F2F) with a lackof technology utilization, changing global conditions such as the COVID-19 pandemic require other solutions urgently without interrupting the software development schedule. For this purpose, online collaborative tools provide new opportunities for software teams to work together avoiding waste in time and resources and the relevant literature is immature. This study aims to assess the factors affecting the integration of online collaborative tools to SE practices with a special reference to review meetings. For this purpose, a sample of 73 SE sophomore and junior students who are future software professionals participated in experimental review meetings based on predefined scenarios. The findings indicate that the utilization of OCT's has positive effects on the participants' actual performance and improves the interaction between team members compared to F2F meetings. © 2021 IEEE

The problem researched is that there presently does not exist a set of success factors which are common across organizations and have some predictability relationship to software reuse. For completeness, this research also investigated possible predictive relationships between software reuse and both productivity and quality. A 1995 survey was conducted to determine the state-of-the-practice. The data from the survey was statistically analyzed to evaluate the relationships among reuse capability, productivity, quality, and the individual software reuse success factors. The results of the analysis showed some of the success factors to have a predictive relationship to software reuse capability. software reuse capability also had a predictive relationship to productivity and quality. Based on the research results, the leading indicators of software reuse capability are: product-line approach, architecture which standardizes interfaces and data formats, common software architecture across the product-line, design for manufacturing approach, domain engineering, management which understands reuse issues, software reuse advocate(s) in senior management, state-of-the-art tools and methods, precedence of reusing high level software artifacts such as requirements and design versus just code reuse, and trace end-user requirements to the components (systems, subsystems, and/or software modules) which support them. © 1997 ACM.

Image deblurring techniques that uses deep learning have shown great potential but due to low generalizability, noise immunity and the correlation among different pixels is not addressed in detail that results in unwanted artifact that appears in the deblurred image. To tackle this problem an end-to-end approach is proposed for the recovery of sharp image from blurred one without the estimation of blur kernel. A special type of attention module known as crosshatch attention is used after Residual Block of Generator model for removing noise and for the collection of correlation of different pixels in an image. Hybrid Loss function is defined which focus on different part of image and improve edges and texture details. The performance of the model for deblurring is measured on GoPro dataset. Our proposed model has slightly higher objective and subjective evaluation i-e PSNR, SSIM value and the visual results. © 2024 IEEE.

This study investigates the performance of traditional Machine Learning (ML) models for Sentiment Analysis (SA) in the Turkish language, addressing the growing need for robust Natural Language Processing (NLP) techniques in low-resource languages. We compare the efficacy of Logistic Regression (LR), Support Vector Machine (SVM), Random Forest (RF), and Naive Bayes (NB) classifiers on two recently developed large-scale Turkish sentiment datasets: "Vitamins and Supplements Customer Review" (VSCR) and "Turkish Sentiment Analysis version 1" (TRSAv1). Our research leverages advanced hyperparameter tuning techniques to optimize these models, providing benchmarks and practical insights for Turkish SA. The study contributes to the field by establishing performance baselines on new open-source datasets, enhancing understanding of NLP models for agglutinative languages, and analyzing factors affecting classifier performance in binary and multi-class scenarios. Our findings reveal the strengths and limitations of each model within the context of Turkish language SA, offering valuable guidance for future research and applications in this domain. © 2024 IEEE.

Wireless sensor networks (WSNs) have emerged as one of the most promising technology to provide a wide variety of industrial applications. However, it is still failing to respond in a timely fashion service. In contrast to existing studies, we propose a more practical standard known as Data Distribution Service (DDS), as a middleware standard for interoperable Data Centric Publish-Subscribe (DCPS) architecture with real-time data distribution capabilities, and a candidate for standards based realizations of equally data centric WSN environments. Especially, this paper aims to evaluate on customized design features for real-time WSNs of an applicable and supportive architecture of DDS-based middleware. In the meantime, to integrate the underlying heterogeneous WSN and DDS, a supportive wireless protocol design is required and, thus, those features could be taken into account in designing the protocol. © 2014 SERSC.
