In this work, we report an ongoing study that aims to apply cluster validation measures for analyzing email communications at an organizational level of a company. This analysis can be used to evaluate the company structure and to produce further recommendations for structural improvements. Our initial evaluations, based on data in the forms of emails logs and organizational structure for a large...
Textual description of requirements is a specification technique that is widely used in industry, where time is key for success. How requirements are specified textually greatly depends on human factors. In order to study how requirements processing is affected by the level of detail in textual descriptions, this paper compares enriched textual requirements specifications with non-enriched ones. To...
Recommender systems take inputs from user history, use an internal ranking algorithm to generate results and possibly optimize this ranking based on feedback. However, often the recommender system is unaware of the actual intent of the user and simply provides recommendations dynamically without properly understanding the thought process of the user. An intelligent recommender system is not only useful...
Free/Open Source Software developers come from a myriad of different backgrounds, and are driven to contribute to projects for a variety of different reasons, including compensation from corporations or foundations. Motivation can have a dramatic impact on how and what contribution an individual makes, as well as how tenacious they are. These contributions may align with the needs of the developer,...
Spreadsheets serve as a basis for decision-making processes in many companies and bugs in spreadsheets can therefore represent a considerable risk to businesses. Systematic tests can help to locate such bugs, but providing test cases can be cumbersome and complex for large real-world spreadsheets. To make the specification of test cases easier, we propose to split spreadsheets into smaller logically...
Process-aware Information Systems (PAIS) have become ubiquitous in companies. Thus the amount of data that can be used to analyze and monitor process executions is vast. The event logs generated by PAIS might contain information about decision making processes and can support the understanding and improving of procedures in companies. Mining decisions and constraints from logs has already been investigated,...
This paper is concerned with the benefits of a price responsive scheme as a demand response program focus on residential end-users. We consider several retail companies operating in the retail market and the Distribution System Operator optimizing the physical resources of the distribution networks. The price responsive scheme is modeled as an OPF problem. We use a decomposition model to formulate...
In task allocation problems one usually only considers a single round in which players participate. In practice, many allocation problems are of repeated nature, in which players can decide to keep participating or leave. Players' participation, or behavior, influences the outcome, or social welfare, of these problems. In this paper, we use a fuzzy connective to model agents' behavior in regard to...
Considering different aspects of knowledge functioning, context is poorly understood in spite of intuitively identifying this concept with environmental recognition. For dynamic knowledge, context especially seems to be an essential factor of change. Investigation on the impact of context on knowledge dynamics or more generally on the relationship between knowledge and its contextual interpretation...
Crowd-based requirements engineering (CrowdRE) is promising to derive requirements by gathering and analyzing information from the crowd. Setting up CrowdRE in practice seems challenging, although first solutions to support CrowdRE exist. In this paper, we report on a German software company's experience on crowd involvement by using feedback communication channels and a monitoring solution for user-event...
Feedback communication channels allow end-users to express their needs, which can be considered in software development and evolution. Although feedback gathering and analysis have been identified as an important topic and several researchers have started their investigation, information is scarce on how software companies currently elicit end-user feedback. In this study, we explore the experiences...
In requirements elicitation interviews, ambiguities identified by analysts can help to disclose the tacit knowledge of customers. Indeed, ambiguities might reveal implicit or hard to express information that needs to be elicited. The perception of ambiguity might depend on the subject who is acting as analyst, and different analysts might identify different ambiguities in the same interview. Based...
This paper presents PURE (PUblic REquirements dataset), a dataset of 79 publicly available natural language requirements documents collected from the Web. The dataset includes 34,268 sentences and can be used for natural language processing tasks that are typical in requirements engineering, such as model synthesis, abstraction identification and document structure assessment. It can be further annotated...
Being able to quickly and accurately capture requirements is crucial when using agile methodologies. Requirements, to that end, are often captured in an as-needed and informal manner, with continuous stakeholder interaction. Techniques such as interviews, user stories, rapid feedback, and text mining are commonly used in the industry to gather such informal requirements, which are often congruent...
The amount of raw data related to electricity companies is increasing rapidly with the increase of construction sites, population and Qatar preparation for 2022 world cup. A question arises from this situation is: How can top level managers keep track of the consumption and plan ahead for the future? The solution is a customized web application that provides an easy way for visualizing the electricity...
In this paper, we propose a method for constructing a judging model of closeness in human relations, which plays an important role in human communication. The purpose of this model is to clarify the correlation between linguistic honorific expressions and closeness in order to develop a support tool related to the utilization of honorific expressions using information technology. Existing studies...
Technical support scams have become more prevalent and turned into a profitable business. We engage 10 technical support scammers from different fake support sites via a live chat and study what kinds of actions they take once we let them control our machine over a remote connection. We then provide a qualitative analysis on the main characteristics of technical support scams that have received little...
Due to the collapse of the bubble economy, many Japanese ICT companies are faced with a tough situation. Each company has implemented various management reforms to restore competitive advantage. However, such attempts were unsuccessful. Although they have large shares in the domestic market, despite struggle against China and Korean companies they have smaller share compared to these two countries...
Consumers in everyday life, especially in terms of the use of cooking food can not be separated from edible oils, especially now many edible oil products on the market made in the form of packaging. Consumers in this case would be to buy the product based on the aspects and criteria in accordance with their wishes. Consumers will buy these products not only look from one criterion alone, there are...
Password advice is constantly circulated by standards agencies, companies, websites and specialists. But there appears to be great diversity in terms of the advice that is given. Users have noticed that different websites are enforcing different restrictions. For example, requiring different combinations of uppercase and lowercase letters, numbers and special characters. We collected password advice...
