Hiring is one of the important challenges in the context of online labor marketplace. Unlike traditional hiring, where workers are hired either as a full time employee or as a contractor, hiring from online marketplaces are done for individual jobs of short duration. As these marketplaces are open for anyone, hiring becomes challenging due to the large number of freelancers applying for a posted job...
In this paper we study the trustworthiness of the crowd for crowdsourced software development. Through the study of literature from various domains, we present the risks that impact the trustworthiness in an enterprise context. We survey known techniques to mitigate these risks. We also analyze key metrics from multiple years of empirical data of actual crowdsourced software development tasks from...
The emergence of online labor markets has concentrated a lot of attention on the prospect of using crowdsourcing for software development, with a potential to reduce costs, improve time-to-market, and access high-quality skills on demand. However, crowdsourcing of software development is still not widely adopted. A key barrier to adoption is a lack of confidence that a task will be completed on time...
Stories occupy a central role in training and instruction, and in many professional contexts is an intrinsic element in the enculturation and education of novice practitioners. “War stories” are valuable pieces of information that experienced mentors share with trainees, and when appropriately selected, can illustrate a concept when the learner is in a position to best understand and apply that concept...
As technological approaches to instruction become more widely available (and expected), developers have turned to authoring tools as a solution to two classic problems: (1) how can software be produced more easily and rapidly; (2) how can teacher practitioners and instructional designers create sophisticated, technology-enhanced curriculum materials without relying on computer programmers and researchers?...
We present and evaluate a software development methodology that addresses key challenges for the application of Crowd sourcing to an enterprise application development. Our methodology presents a mechanism to systematically break the overall business application into small tasks such that the tasks can be completed independently and in parallel by the crowd. Our methodology supports automated testing...
In this paper, we present a distributed way to automatically map users' requirements to reference process models. In a prior paper [9], we presented a tool called Process Model Requirements Gap Analyzer (ProcGap), which combines natural language processing, information retrieval, and semantic reasoning to automatically match and map textual requirements to domain-specific process models. Although...
This paper describes how a computer program can support learning by retrieving and presenting relevant stories drawn from a video case base. Although this is an information retrieval problem, it is not a problem that fits comfortably within the classical IR model of Salton and McGill. In the classical model the computer system is passive: it is assumed that the user will take the initiative to formulate...
