In 2017, the contact center industry generated $200 billion in revenue worldwide, contributing to a significant proportion of market share, and yet businesses lost $75 billion due to poor customer satisfaction. Around 48% of consumers prefer using phones as their mode of communication with contact centers. Analysis of these calls can give insights into customer views and help businesses improve their customer engagement. To understand the structure and flow of the conversation, the conversation transcript can be segmented into meaningful sections such as “greeting exchange” “problem description” and “problem resolution”, to name a few. In this paper, we present a comparative study of various unsupervised methods of dialogue segmentation. We choose three classic unsupervised text segmentation techniques: TextTiling, TopicTiling, and Content Vector Segmentation, and evaluate their performance on 50 manually labeled dialogue conversation transcripts. The transcripts used span across contact center calls, live chat, interactions with chat-bots and talk show conversations. Additionally, we build on the TextTiling algorithm by incorporating semantic word embeddings for text representation. We show that this modification outperforms the three benchmarked approaches with a mean Pk value of 0.31, indicating that 69% of the boundaries are identified accurately at an average.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128713585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Comparison of Different Spatial Interpolation Techniques to Thematic Mapping of Socio-Economic Causes of Crime Against Women","authors":"Aamil Rastogi, Smriti Sridhar, R. Gupta","doi":"10.1109/SIEDS49339.2020.9106690","DOIUrl":"https://doi.org/10.1109/SIEDS49339.2020.9106690","url":null,"abstract":"The increase in the crime rate numbers and a rise in the need to find better solutions to handle information about criminality is affected by the ever-changing socio-economical order of the world. Despite the number of solutions implemented for reducing crime (against women), cities continue to have an unsafe environment. The prime drawback lies in the inability to provide a prompt response in real-time when in danger. Thus, the effective utilization of technology in public safety management is important. The present state of the art solutions focus on technological innovations with limited human intervention and are insufficient in ensuring the safety of the women as and when required. To dig deeper into the root cause of preventing a crime from occurring in a particular place, it is vital to analyze the parameters and factors contributing to the crime in a community. This research applies the Information Communication Technologies (ICT) along with harnessing big data tools to identify crime hotspots and patterns. After a comprehensive literature review, it has been noted that there are different social-economic factors affecting the crime in an area. The proposed work aims to integrate the socio-economic attributes leading to increasing crime against women. Interpolation strategies used for thematic maps generation also play a major role in predicting and studying the area affected by a crime. This research initially identifies the various social-economical parameters that affect crime against women. Some of them to mention include unemployment, illiteracy, population, sex ratio, traffic, age, no. of schools, and location of liquor shops. Subsequently, a comparison of major interpolation methods used in crime mapping: Inverse Distance Weighted (IDW), Kriging, and Spline are formulated to understand the overall contribution of socio-economic factors on the crime thematic map to further ascertain if one parameter poses substantially more important than the other. The comparison of different Interpolation techniques used in pixel by pixel error analysis on high definition satellite images of the crime site, of resolution as high as 2.5m x 2.5m, is created using visualization libraries like Matplotlib and Seaborn. Finally, the thematic maps are created using the best Interpolation technique chosen and help in predicting the pattern of the crime. The proposed framework developed using Geographic Information System (GIS) based visualization and big data tools for crime mapping can then be applied in the development of user interactive platforms and designing safety strategies to help the needy in real-time. To validate the methodology, a case study is performed with real data, in the Jhunjhunu district of Rajasthan, India.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115839907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Ryan White HIV/AIDS Program (RWHAP) provides funding for HIV medical care and medications for people living with HIV. The RWHAP program received 2.34 billion dollars in 2018 and the Ending the HIV Epidemic initiative was awarded 117 million dollars in 2020. However, even with increased funding, geographic barriers to accessing HIV care can prevent people from obtaining treatment. Additionally, the impact of insurance status (none, Medicaid, Affordable Care Act plans) on drive times to HIV care is not well understood. Geographic access to RWHAP clinics in the contiguous United States was examined. Using spatial analysis techniques, the duration of drive time from the center of every county equivalent to the nearest accessible RWHAP clinic was measured. Counties were characterized in terms of social determinants of health and HIVrelated variables and their associations with access to HIV care were examined.The effect of insurance status on drive times was analyzed in order to measure its impact by being uninsured, enrolled in Medicaid, or enrolled in either the least or most expensive Affordable Care Act plans.Four hundred twenty-seven RWHAP locations were identified with a median county-level drive time of 64.6 minutes (interquartile range (IQR) 40.9-97.9) for counties with five or more diagnosed HIV cases. The median drive time for Medicaid access was 69.3 minutes (IQR 42.2-106.0), with some states impacted more than others. These findings were used to make specific policy recommendations to improve access and reduce barriers to HIV care.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115598217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the onset of online banking services, it has become important to both understand the latent behavioral patterns behind attrition and predict the event of attrition well before losing a customer. Presently, attrition models measure hard attrition, the event of a customer closing their account. By introducing a new latent probabilistic response variable, soft attrition, we aim to identify customers that tend towards attrition, which (i) increases the comprehensiveness of the customer base that is likely to churn, (ii) improves capability of predicting attrition events early, and (iii) helps identify key features associated with attrition. This paper introduces and evaluates methods that help redefine the attrition response variable and proposes techniques that improve on the existing attrition models, specifically in the retail banking industry.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114218925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ignoring active stop signs and crossing arms on school buses that are boarding and deboarding children at stops is a serious traffic violation, but it is difficult to prosecute drivers who are guilty of these offenses due to the lack of surveillance and monitoring systems that can provide critical violation information to law enforcement agencies. This study aims to address the issue of illegal passing of school buses prevailing in small towns and cities where lack of sufficient oversight exists. A detection system incorporating a solid-state LiDAR unit and a dashcam, both of which are controlled by a Raspberry Pi computer, was designed. The primary function of the system is to capture an image of the license plate of the violating vehicle and make that data available to law enforcement agencies, enabling those agencies to take appropriate enforcement action, which in turn will serve as a deterrent to mitigate future accidents. Several state legislative bodies have passed related bills and have urged researchers to find solutions to address the issue. This detection system achieves two keys goals: reducing overall cost of system implementation and reducing video review time. It is a potential component for a comprehensive solution to the school bus passing problem.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128145047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When such conflicts arise, it takes time to get everyone back into a receptive state of mind so that they engage in reflective discussion rather than unproductive arguing. It has been proposed by some that the use of social robots equipped with social abilities such as emotion regulation through rapport building may help to deescalate these situations to facilitate critical operational decisions. However, in military settings, the same AI agent used in the pre-brief of a mission may not be the same one used in the debrief. The purpose of this study was to determine whether a brief rapport-building session with a social robot could create a connection between a human and a robot agent, and whether consistency in the embodiment of the robot agent was necessary for maintaining this connection once formed. We report the results of a pilot study conducted at the United States Air Force Academy which simulated a military mission (i.e., Gravity and Strike). Participants’ connection with the agent, sense of trust, and overall likeability revealed that early rapport building can be beneficial for military missions.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126529282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

National Airspace System (NAS) present a fundamental challenge to capacity growth under ever-increasing traffic volumes, and lead to significant financial burdens that reverberate across a multitude of aviation industry stakeholders. Roughly 20% of passengers’ total travel time is due to such delays, causing $35 billion annually in lost revenue and impacting not only the airline industry, but the retail, lodging, restaurant, and tourism industries, as well. The Federal Aviation Administration’s effort in aiding decision-making at airports is readily apparent in the Next Generation Air Traffic Control (NextGen) System’s System-Wide Information Management (SWIM) program, and in-flight delay information from the FAA Air Traffic Control System Command Center (ATCSCC). Academic researchers are concurrently developing various algorithms to predict flight delays that include advanced statistics, machine learning, and graph theory using various network topologies. Other stakeholders have initiated delay prediction methods to adjust their operational schedules. This suggests an opportunity to centralize, validate, and integrate the various delay prediction methods under development; furthermore, these methods are limited in scope with regard to geography, operators, and efficacy.The authors propose here a platform supporting the FAA’s Collaborative Decision-Making (CDM) process with the intent of reducing flight delays in the NAS. Building upon existing deep learning algorithms and utilizing the NextGen SWIM program, this research suggests a central delay prediction platform suited to the complex and dynamic needs of America’s airport infrastructure. assessments of risks and sustainability of the proposed platform are presented. The authors interviewed experts in industry and academic fields related to aviation and information technology, and used the information obtained to refine the model. It is anticipated that this model will accurately produce location-specific departure and arrival delay forecasts that can further be integrated into the CDM and Ground Delay Program (GDP) initiatives.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121700235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, are they looking at the most important metrics and more broadly, how should they identify employees to promote? The literature predominantly focuses on the measurement of performance, but businesses also need instruments that can predict management potential for promotional decision-making. This paper utilizes the data contained in the Human Resources Information System (HRIS) of a company to analyze drivers of potential for promotion among a sample of its workers. Numerous prior studies have been conducted of human resource variables in a variety of organizations. These studies share in common the use of linear models to report which explanatory variables are statistically significant determinants of the dependent variable – in most cases the performance of employees with a focus on the individual’s output. What they do not deliver, and what this study provides, in addition to regression studies on employee performance, is an analysis of the drivers of promotion potential for management roles. The perspective of our analysis diverges from others in that its primary focus is to identify future leaders of a company rather than identifying strong individual contributors. The methods used consist of basic statistical procedures, multiple classification methods and graph theory analysis. In our study of managerial potential drivers, the logistic regression model performs with the best predictive accuracy and recognizes which factors in a manager reveals leadership potential. In our study of promotion potential from a teamwork perspective, we show that graph network-based methods adapt well to employee data containing several bilateral relationships while preserving the hierarchy of an organization and providing defensible accuracy.","PeriodicalId":331495,"journal":{"name":"2020 Systems and Information Engineering Design Symposium (SIEDS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121125639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper provides a framework for how smartphone sensor data can be collected, cleaned, stored, and modeled to effectively predict human states as a step towards health monitoring. To develop robust contextual models, a three-week study was conducted to collect data through a mobile crowdsensing application named Sensus. In this study, participants used multiple sensing strategies, ranging from infrequent sampling to continuous sampling, to determine the effect each has on data integrity and battery life. For a future study, a dynamic data collection strategy was developed that uses a machine learning model trained on existing data collected from 220 participants to forecast when a smartphone will be active and trigger sensor sampling accordingly. Results of this study include 1) extraction of model features that deliver maximized data quality with minimized battery consumption as compared to pre-existing baseline models, 2) implementation of context-driven modeling of user smartphone data on user's contextual environment, and 3) customization of a time-series database for optimized data queries used in metadata visualizations.
