Increasing amounts of data have made the use of machine learning techniques much more widespread. A lot of research in machine learning has been dedicated to the design and application of effective and efficient algorithms to explain or predict facts. The development of intelligent machines that can learn over extended periods of time, and that improve their abilities as they execute more tasks...

Literature base discovery has been used for many years as a way to identify possible discoveries of related concepts where the concepts have never been mentioned previously in the same document. Linking concepts and the nature of the relationship between the hidden discovery and the linking concepts may be gleaned from the documents using existing relationship extraction techniques. Little has ...

Quantitative structure activity relationships (QSARs) are functions that predict bioactivity from compound structure. Although almost every form of statistical and machine learning method has been applied to learning QSARs, there is no single best way of learning QSARs. Therefore, currently the QSAR scientist has little to guide her/him on which QSAR approach to choose for a specific problem. T...

Remote, automated cognitive impairment (CI) diagnosis has the potential to facilitate care for the elderly. Speech is easily collected over the phone and already some common cognitive tests are administered remotely, resulting in regular audio data collections. Speech-based CI diagnosis leveraging existing audio is therefore an attractive approach for remote elderly cognitive health monitoring....

Abstract The relationship between firms’ owners and managers is a quintessential example of costly principal–agent interaction. Optimal design monetary incentives supervision mechanisms are the two traditional ways reducing agency costs in this relationship. In paper, we show evidence which consistent with third mechanism: firms have whose economic preferences aligned owners' interests. We unco...

Several metadata schemas focusing on Dublin Core metadata are now in operation around the world. In this demonstration, we support participants in exploring various components that make up the IEMSR metadata schema registry: a desktop tool enabling creation of simple DC vocabularies and application profiles and their addition to the registry; a Web client that enables the registry to be browsed...

Introduction: The two-sided matching model of Gale and Shapley (1962) can be interpreted as one where a non-empty finite set of firms need to employ a non-empty finite set of workers. Further, each firm can employ at most one worker and each worker can be employed by at most one firm. Each worker has preferences over the set of firms and each firm has preferences over the set of workers. An ass...

Customer response is a crucial aspect of service business. The ability to accurately predict which customer profiles are productive has proven invaluable in customer relationship management. An area that has received little attention in the literature on direct marketing is the class imbalance problem (the very low response rate). We propose a customer response predictive model approach combini...

The relationship between labour demand and job-to-job movement is investigated, both theoretically and empirically, at the macro level. It concentrates on the role of the employment regime (hiring, do-nothing or ® ring) and the hiring and ® ring costs. The exact upper bounds of the marginal hiring costs of an employed worker are derived, for which job mobility between two ® rms yields a positiv...

Numerous gift exchange experiments have found a positive wage-effort relationship. In (almost) all these experiments the employer both owns and controls the firm. This paper explores to what extent the separation of ownership and control affects the wage-effort relationship. We compare the standard bilateral gift exchange game between an owner-manager and a worker with two trilateral ones where...
