1 Text mining of industry 4:0 job advertisements
استخراج متن آگهی های شغلی صنعت 4:0-2020
Since changes in job characteristics in areas such as Industry 4.0 are rapid, fast tool for analysis of job advertisements is needed. Current knowledge about competencies required in Industry 4.0 is scarce. The goal of this paper is to develop a profile of Industry 4.0 job advertisements, using text mining on publicly available job advertisements, which are often used as a channel for collecting relevant information about the required knowledge and skills in rapid-changing industries. We searched website, which publishes job advertisements, related to Industry 4.0, and performed text mining analysis on the data collected from those job advertisements. Analysis of the job advertisements revealed that most of them were for full time entry; associate and mid-senior level management positions and mainly came from the United States and Germany. Text mining analysis resulted in two groups of job profiles. The first group of job profiles was focused solely on the knowledge related to Industry 4.0: cyberphysical systems and the Internet of things for robotized production; and smart production design and production control. The second group of job profiles was focused on more general knowledge areas, which are adapted to Industry 4.0: supply change management, customer satisfaction, and enterprise software. Topic mining was conducted on the extracted phrases generating various multidisciplinary job profiles. Higher educational institutions, human resources professionals, as well as experts that are already employed or aspire to be employed in Industry 4.0 organizations, would benefit from the results of our analysis.

3 Business analytics for strategic management: Identifying and assessing corporate challenges via topic modeling
تجزیه و تحلیل کسب و کار برای مدیریت استراتژیک: شناسایی و ارزیابی چالش های شرکت از طریق مدل سازی موضوع-2020
Strategic management requires an assessment of a firms internal and external environments. Our work extends the body of management tools (e.g., SWOT analysis or growth-share matrix) by proposing an automated text mining framework. Here we draw on narrative materials from firms (e.g., financial disclosures) and perform topic modeling so as to identify the key issues faced by an organization. We then quantify the use of language along two dimensions: risk and optimism. This reveals a firms strengths and weaknesses by identifying business units, activities, and processes subject to risk, while also comparing it with competitors or the market.

4 What can the news tell us about the environmental performance of tourist areas? A text mining approach to China’s National 5A Tourist Areas
چه خبرهایی می تواند از عملکرد زیست محیطی مناطق توریستی به ما بگوید؟ یک رویکرد استخراج متن به مناطق گردشگری ملی 5A در چین-2020
This study aims to evaluate the environmental performance status of tourist areas and explore the influencing factors using text mining of web news. As the leading tourist attractions in China, the National 5A Tourist Areas face severe environmental challenges, and were hence chosen to exemplify the rapid assessment approach in the big data era. This study used over 1,300,000 words from online news sources and assessed the environmental performance of 120 National 5A Tourist Areas to conclude that (1) water is the most impacted environmental resource; (2) tourist area environmental performance can be classified into (a) environmental pollution, (b) ecological and resource pressure, (c) landscape character issues and (d) others; and (3) the primary factors influencing the environment are tourism and business operating activities, with the tourist areas’ environmental performance types being strongly related to their spatial locations and weakly related to their resource types. By comparing the environmental performance types in this paper with related research the effectiveness of this study’s approach is validated. These conclusions and this approach can provide guidelines and tools for environmental assessment and promote tourist area management

5 The Diffusion Barriers of AI Mobility Service: the Case of TADA
موانع انتشار خدمات تحرک هوش مصنوعی: مورد TADA-2020
TADA, AI-based smart mobility service in Korea, has been indicted for violating the act in Korea despite the uncertainty of whether it is illegal or not. The main reason for this is that TADA has not found a way to coexist with traditional mobility companies. The TADA case shows that the diffusion of innovation is affected by a variety of social issues, not just technical or business issues. Thus, this study analyzes public perceptions of the TADA case and discusses what are the social barriers to AI innovation. The results of this study show that the diffusion of innovative services requires discussions with various stakeholders in addition to technical or business efforts.

داده کاوی برای سیستمهای حقوقی هوشمند-2019
Smart legal systems carry immense potential to provide legal community and public with valuable insights using legal data. These systems can consequently help in analyzing and mitigating various social issues. In Pakistan, since last couple of years, courts have been reporting judgments online for public consumption. This public data, once processed, can be utilized for betterment of society and policy making in Pakistan. This study takes the first step to realize smart legal system by extracting various entities such as dates, case numbers, reference cases, person names, etc. from legal judgments. To automatically ex- tract these entities, the primary requirement is to construct dataset using legal judgments. Hence, firstly annotation guidelines are prepared followed by preparation of annotated dataset for extraction of various legal entities. Experiments conducted using variety of datasets, multiple algorithms and annotation schemes, resulted into maximum F1-score of 91.51% using Conditional Random Fields

7 Detecting adverse drug reactions in discharge summaries of electronic medical records using Readpeer
بررسی عوارض جانبی دارویی در خلاصه تخلیه سوابق پزشکی الکترونیکی با استفاده از Readpeer-2019
Background: Hospital discharge summaries offer a potentially rich resource to enhance pharmacovigilance efforts to evaluate drug safety in real-world clinical practice. However, it is infeasible for experts to read through all discharge summaries to find cases of drug-adverse event (AE) relations. Purpose: The objective of this paper is to develop a natural language processing (NLP) framework to detect drug- AE relations from unstructured hospital discharge summaries. Basic procedures: An NLP algorithm was designed using customized dictionaries of drugs, adverse event (AE) terms, and rules based on trigger phrases, negations, fuzzy logic and word distances to recognize drug, AE terms and to detect drug-AE relations. Furthermore, a customized annotation tool was developed to facilitate expert review of discharge summaries from a tertiary hospital in Singapore in 2011. Main findings: A total of 33 trial sets with 50 to 100 records per set were evaluated (1620 discharge summaries) by our algorithm and reviewed by pharmacovigilance experts. After every 6 trial sets, drug and AE dictionaries were updated, and rules were modified to improve the system. Excellent performance was achieved for drug and AE entity recognition with over 92% precision and recall. On the final 6 sets of discharge summaries (600 records), our algorithm achieved 75% precision and 59% recall for identification of valid drug-AE relations. Principal conclusions: Adverse drug reactions are a significant contributor to health care costs and utilization. Our algorithm is not restricted to particular drugs, drug classes or specific medical specialties, which is an important attribute for a national regulatory authority to carry out comprehensive safety monitoring of drug products. Drug and AE dictionaries may be updated periodically to ensure that the tool remains relevant for performing surveillance activities. The development of the algorithm, and the ease of reviewing and correcting the results of the algorithm as part of an iterative machine learning process, is an important step towards use of hospital discharge summaries for an active pharmacovigilance program

8 Validation of text-mining and content analysis techniques using data collected from veterinary practice management software systems in the UK
اعتبارسنجی تکنیک های استخراج متن و تجزیه و تحلیل محتوا با استفاده از داده های جمع آوری شده از سیستم های نرم افزار مدیریت دامپزشکی در انگلستان-2019
Electronic patient records from practice management software systems have been used extensively in medicine for the investigation of clinical problems leading to the creation of decision support frameworks. To date, technologies that have been utilised for this purpose such as text mining and content analysis have not been employed significantly in veterinary medicine. The aim of this research was to pilot the use of content analysis and text-mining software for the synthesis and analysis of information extracted from veterinary electronic patient records. The purpose of the work was to be able to validate this approach for future employment across a number of practices for the purposes of practice based research. The approach utilised content analysis (Prosuite) and text mining (WordStat) software to aggregate the extracted text. Text mining tools such as Keyword in Context (KWIC) and Keyword Retrieval (KR) were employed to identify specific occurrences of data across the records. Two different datasets were interrogated, a bespoke test dataset that had been set up specifically for the purpose of the research, and a functioning veterinary clinic dataset that had been extracted from one veterinary practice. Across both datasets, the KWIC analysis was found to have a high level of accuracy with the search resulting in a sensitivity of between 85.3–100%, a specificity of between 99.1–99.7%, a positive predictive value between 93.5–95.8% and a negative predictive value between 97.7–100%. The KR search, based on machine learning, was utilised for the clinic-based dataset and was found to perform slightly better than the KWIC analysis. This study is the first to demonstrate the application of content analysis and text mining software for validation purposes across a number of different datasets for the purpose of search and recall of specific information across electronic patient records. This has not been demonstrated previously for small animal veterinary epidemiological research for the purposes of large scale analysis for practice-based research. Extension of this work to investigate more complex diseases across larger populations is required to fully explore the use of this approach in veterinary practice.

9 Using big data database to construct new GFuzzy text mining and decision algorithm for targeting and classifying customers
استفاده از بانک اطلاعاتی داده های بزرگ برای ساخت الگوریتم تصمیم گیری متن کاوی GFuzzy برای هدف قرار دادن و طبقه بندی مشتریان-2019
After an enterprise builds a data warehouse, it can record information related to customer interactions using structured and unstructured data. The intention is to convert these data into useful information for decisionmaking to ensure business continuity. Hence, this study proposes a new Chinese text classification model for the project management office (PMO) using fuzzy semantics and text mining techniques. First, content analysis is performed on the unstructured data to convert important textual information and compile it into a keyword index. Next, a classification and decision algorithm for grey situations and fuzzy (GFuzzy) is used to categorize textual data by three characteristics: maximum impact, moderate impact, and minimum impact. The purpose is to analyze consumer behaviors for the accurate classification of customers. Lastly, a more effective marketing strategy is formulated to target the various customer combinations, growth models, and the best mode of service. A company database of interactions with customers is used to construct a text mining model and to analyze the decision process of its PMO. The purpose is to test the feasibility and validity of the proposed model so that enterprises are provided with better marketing strategies and PMO processes aimed at their customers

10 A decision support system based on ontology and data mining to improve design using warranty data
یک سیستم پشتیبانی تصمیم گیری مبتنی بر هستی شناسی و داده کاوی برای بهبود طراحی با استفاده از گارانتی داده ها -2019
Analysis of warranty based big data has gained considerable attention due to its potential for improving the quality of products whilst minimizing warranty costs. Similarly, customer feedback information and warranty claims, which are commonly stored in warranty databases might be analyzed to improve quality and reliability and reduce costs in areas, including product development processes, advanced product design, and manufacturing. However, three challenges exist, firstly to accurately identify manufacturing faults from these multiple sources of heterogeneous textual data. Secondly, accurately mapping the identified manufacturing faults with the appropriate design information and thirdly, using these mappings to simultaneously optimize costs, design parameters and tolerances. This paper proposes a Decision Support System (DSS) based on novel integrated stepwise methodologies including ontology-based text mining, self-organizing maps, reliability and cost optimization for identifying manufacturing faults, mapping them to design information and finally optimizing design parameters for maximum reliability and minimum cost respectively. The DSS analyses warranty databases which collect the warranty failure information from the customers in a textual format. To extract the hidden knowledge from this, an ontology-based text mining based approach is adopted. A data mining based approach using Self Organizing Maps (SOM) has been proposed to draw information from the warranty database and to relate it to the manufacturing data. The clusters obtained using SOM are analyzed to identify the critical regions, i.e., sections of the map where maximum defects occur. Finally, to facilitate the correct implementation of design parameter changes, the frequency and type of defects analyzed from warranty data are used to identify areas where improvements have resulted in the greatest reliability for the lowest cost.
Keywords: Ontology | Self-Organizing Maps | Warranty data | Text mining | Decision support
