The Application of Artificial Intelligence in Project Management Research: A Review
The field of artificial intelligence is currently experiencing relentless growth, with innumerable models emerging in the research and development phases across various fields, including science, finance, and engineering. In this work, the authors review a large number of learning techniques aimed at project management. The analysis is largely focused on hybrid systems, which present computational models of blended learning techniques. At present, these models are at a very early stage and major efforts in terms of development is required within the scientific community. In addition, we provide a classification of all the areas within project management and the learning techniques that are used in each, presenting a brief study of the different artificial intelligence techniques used today and the areas of project management in which agents are being applied. This work should serve as a starting point for researchers who wish to work in the exciting world of artificial intelligence in relation to project leadership and management

Establishment of Landslide Groundwater Level Prediction Model Based on GA-SVM and Influencing Factor Analysis
The monitoring and prediction of the landslide groundwater level is a crucial part of landslide early warning systems. In this study, Tangjiao landslide in the Three Gorges Reservoir area (TGRA) in China was taken as a case study. Three groundwater level monitoring sensors were installed in different locations of the landslide. The monitoring data indicated that the fluctuation of groundwater level is significantly consistent with rainfall and reservoir level in time, but there is a lag. In addition, there is a spatial difference in the impact of reservoir levels on the landslide groundwater level. The data of two monitoring locations were selected for establishing the prediction model of groundwater. Combined with the qualitative and quantitative analysis, the influencing factors were selected, respectively, to establish the hybrid Genetic Algorithm-Support Vector Machine (GA-SVM) prediction model. The single-factor GA-SVM without considering influencing factors and the backpropagation neural network (BPNN) model were adopted to make comparisons. The results showed that the multi-factor GA-SVM performed the best, followed by multi-factor BPNN and single-factor GA-SVM. We found that the prediction accuracy can be improved by considering the influencing factor. The proposed GA-SVM model combines the advantages of each algorithm; it can effectively construct the response relationship between groundwater level fluctuations and influencing factors. Above all, the multi-factor GA-SVM is an effective method for the prediction of landslides groundwater in the TGRA
Artificial Intelligence Enabled Project Management: A Systematic Literature Review
In the Industry 5.0 era, companies are leveraging the potential of cutting-edge technologies such as artificial intelligence for more efficient and green human-centric production. In a similar approach, project management would benefit from artificial intelligence in order to achieve project goals by improving project performance, and consequently, reaching higher sustainable success. In this context, this paper examines the role of artificial intelligence in emerging project management through a systematic literature review; the applications of AI techniques in the project management performance domains are presented. The results show that the number of influential publications on artificial intelligence-enabled project management has increased significantly over the last decade. The findings indicate that artificial intelligence, predominantly machine learning, can be considerably useful in the management of construction and IT projects; it is notably encouraging for enhancing the planning, measurement, and uncertainty performance domains by providing promising forecasting and decision-making capabilities
On the Role of Genetic Algorithms in the Pattern Recognition Task of Classification
In this dissertation we ask, formulate an apparatus for answering, and answer the following three questions: Where do Genetic Algorithms fit in the greater scheme of pattern recognition? Given primitive mechanics, can Genetic Algorithms match or exceed the performance of theoretically-based methods? Can we build a generic universal Genetic Algorithm for classification? To answer these questions, we develop a genetic algorithm which optimizes MATLAB classifiers and a variable length genetic algorithm which does classification based entirely on boolean logic. We test these algorithms on disparate datasets rooted in cellular biology, music theory, and medicine. We then get results from these and compare their confusion matrices. For those unfamiliar with Genetic Algorithms, we include a primer on the subject in chapter 1, and include a literature review and our motivations. In Chapter 2, we discuss the development of the algorithms necessary as well as explore other features necessitated by their existence. In Chapter 3, we share and discuss our results and conclusions. Finally, in Chapter 4, we discuss future directions for the corpus we have developed

Analisis Sentimen pada Ulasan Buku Berbahasa Inggris Menggunakan Information Gain dan Support Vector Machine
Informasi yang terdapat di Internet sangat bermacam-macam, salah satunya adalah informasi mengenai buku. Jika informasi tersebut diolah dengan baik maka akan diperoleh kualitas buku dari informasi tersebut. Dengan membaca ulasannya, maka kita akan mengetahui kualitas dan juga menganalisis sentimen positif dan juga sentimen negatif dari buku tersebut. Namun, begitu banyaknya opini akan mempersulit pengguna lain untuk memperoleh kualitas dari informasi tersebut. Analisis sentimen merupakan penilaian seseorang tentang topik yang dibahas baik itu sentimen positif ataupun sentimen negatif. Untuk mempercepat dalam menganalisis banyaknya sentimen yang ada, digunakanlah metode klasifikasi yaitu Support Vector Machine . Kelebihan dari SVM ini yaitu untuk menentukan hyperplane yang dapat menghasilkan margin yang maksimal antara kelas yang satu dengan kelas yang lainnya. Tetapi SVM mempunyai kelemahan terhadap pilihan fitur atau parameter yang dapat mempengaruhi akurasi. Maka dari itu, pada penelitian ini mengunakan metode Information Gain agar dapat meningkatkan akurasi dengan mengurangi jumlah fitur yang akan dianalisis dan Support Vector Machine sebagai metode klasifikasi untuk menangani permasalahan ini dan hasil dari penelitian ini menghasilkan nilai rata-rata F1-score sebesar 82.35%

Analisis Sentimen Pengguna Sistem Pay Later Menggunakan Support Vector Machine Metode Pembobotan Lexicon
Layanan pay later sangat mudah dengan cepat populer di masyarakat, hal ini disebabkan karena fitur ini cenderung mudah digunakan dan populer karena tertanam pada e-commerce. Banyaknya penyedia layanan pay later menyebabkan diperlukannya pemilahan penyedia paylater mana yang akan digunakan berdasarkan berbagai pertimbangan termasuk review dari pengguna lain. Di sisi lain, review pengguna lain dapat diperoleh dari Twitter. Data dari Twitter menunjukkan terdapat ribuan tweets pada tahun 2021 hingga 2022 berisikan opini masyarakat terkait penggunaan pay later. Tweets tersebut membahas tentang keunggulan, keluhan, dan ulasan dari penggunaan pay later. Namun, beberapa keunggulan, keluhan, dan ulasan tersebut banyak yang bersifat abstrak sehingga masih belum optimal pemanfaatannya. Penelitian ini bertujuan untuk mengklasifikasikan data tweet yang berkaitan dengan pay later menggunakan algoritma Support Vector Machine (SVM). Dari penelitian ini telah berhasil dibangun model klasifikasi SVM untuk kasus sentimen Shopee Paylater dan Go Paylater. Pada pemodelan sentimen Shopee Paylater diperoleh bahwa model telah dapat memprediksi kelas data uji dengan akurasi 89.74%. Pada pemodelan sentimen Go Paylater diperoleh bahwa model telah dapat memprediksi kelas data uji dengan akurasi 90.27%.
