background: personal information management (pim) refers to the tools and activities to save and retrieve personal information for future uses. this study examined the pim activities of faculty members of iran university of medical sciences (iums) regarding their preferred pim tools and four aspects of acquiring, organizing, storing and retrieving personal information.   methods : the qualitati...

The notion of 'integration' in the context of health information systems is ill-defined yet in widespread use. We identify a variety of meanings ranging from the purely technical integration of information systems to the integration of services. This ambiguity (or interpretive flexibility), we argue, is inherent rather than accidental: it is a necessary prerequisite for mobilizing political and...

Neural maps project data from an input space onto a neuron position in a (often lower dimensional) output space grid in a neighborhood preserving way, with neighboring neurons in the output space responding to neighboring data points in the input space. A map-learning algorithm can achieve an optimal neighborhood preservation only, if the output space topology roughly matches the effective stru...

People can organize information items by placing them into folders or by tagging them with labels. Over the years there has been considerable discussion on the relative merits of folders vs. labels. But there is relatively little empirical data directly comparing people’s experiences with each model of organization on comparable sets of information.. We compared participants’ experiences organi...

The hybridisation of different classification and mining techniques coming from different areas such as the numeric and the symbolic worlds can produce a significant enhancement of the overall classification and retrieval performance in a Data Mining or Information Retrieval context. This paper introduces an experimental methodology to match an explicative structure issued from a symbolic class...

We introduce a method for deriving a metric, locally based on the Fisher information matrix, into the data space. A self-organizing map (SOM) is computed in the new metric to explore financial statements of enterprises. The metric measures local distances in terms of changes in the distribution of an auxiliary random variable that reflects what is important in the data. In this paper the variab...

Structured Abstract Purpose. Research has shown that when presenting large amounts of social media information on small devices, design should consider multiple contexts which include user preferences, time, location, environment and so on. It should also take into account the purpose of use, for example, the kind of tasks undertaken by users. However, little research has been done on the organ...

A new family of self-organizing maps, the Winner-Relaxing Kohonen Algorithm, is introduced as a generalization of a variant given by Kohonen in 1991. The magnification behaviour is calculated analytically. For the original variant a magnification exponent of 4/7 is derived; the generalized version allows to steer the magnification in the wide range from exponent 1/2 to 1 in the one-dimensional ...

Green information systems (Green IS) are innovative tools that can assist in achieving environmental sustainability. We investigate the manner in which institutional arrangements are brought about during the development of the Vessel Management System (VMS), a Green IS that was developed by a South Australian regulator and used for monitoring compliance with environmental protection legislation...
