Predictive process monitoring emerged as a technique to anticipate the outcome of a running instance of a business process. To this end, it first constructs a forecast model based on an encoding of traces of past process executions that are labelled with the prediction target. This model is then used to predict the outcome of a running process instance. However, existing approaches neglect that real-world...
As spatiotemporal sensor data collections are becoming more available, the ability to generate insights from them is turning increasingly complex for scientists in this domain. Organizing such voluminous data and keeping track of analysis results get tedious from day to day. In this paper, we propose a system comprising a distributed workflow execution engine, a storage framework with flexible spatiotemporal...
Email is a reliable, confidential, fast, free and easily accessible form of communication. Due to its wide use in personal, but most importantly, professional contexts, email represents a valuable source of information that can be harvested for understanding, reengineering and repurposing undocumented business processes of companies and institutions. Few researchers have investigated the problem of...
Cloud service monitoring is a critical need for both providers and customers to assess the state of resources and the level of delivery of services. However, existing Cloud service monitoring methods are typically inapplicable in case the targeted service parameters are inaccessible, e.g., Cloud Service Providers do not allow external access to some service parameters for varied reasons (proprietary...
Cloud platforms and services usually provide an APIlayer as decoupled, language agnostic interface for both front-endclient integration and back-end data and/or function access. Theavailability and performance of the APIs have significant impact onthe quality of end user or client experiences due to its nature ofinteraction endpoints. However, the extreme dynamics, complexityand scale of the current...
Optimum Bid price estimation is crucial for Amazon Elastic Compute Cloud (EC2) consumers if they want to secure uninterrupted access to Spot instances at reduced costs. We recently reported that Bid price estimation is an implicit function of seasonal components and extreme spikes in the Spot price history. In this paper we apply time series forecasting to further substantiate this claim. In particular,...
This paper is faced with group sensing problem, where HD map producers motivate private cars to collect data from real world. Group sensing needs vehicles to communicate physically, and drivers to collaborate strategically. First we consider communication module, three VANET-based methods are proposed to achieve inter-vehicle message relaying. Secondly, we consider collaboration module which motivates...
Finding parking at a desired spot and time is tough, especially in an urban area. Users may also want to pay more to get a parking spot during urgent need. Although the existing infrastructure-based approaches can solve this problem partially, they require a high initial investment and maintenance cost. As a consequence, deploying such approaches on a large scale in the real world is infeasible. A...
While there are several metrics to measure business process performance, recently there is an additional requirement from businesses to evaluate business processes based on their impact on users. In this work, we evaluate business process performance using social media analytics. We view a marketing campaign as a business process and we evaluate its performance based on its impact on the Twitter....
In the cloud platform, there exist multiple providers offering the same web service, and multiple consumers requiring the same web service. Web service providers (consumers) compete against each other to make a deal with service consumers (providers). Each service provider needs to determine a proper ask to sell the service, while each consumer needs to determine a proper bid to purchase the service...
