My presentation provides an eeort towards nding a common understanding on how user and learner modeling systems, if seen as agents, can communicate with the applications. The fundamental characteristics of the communication between application agents (Apps) and user or learner modeling systems (ULMSs) will be examined in order to draw some conclusions on what features should be considered withi...

Understanding the context, structure, activities, and content of software development processes found in practice has been and remains a challenging problem. In the world of free/open source software development, discovering and understanding what processes are used in particular projects is important in determining how they are similar to or different from those advocated by the software engin...

Requirements analysis usually results in a set of di erent speci cations for the same system which must be integrated Integration involves the detection and elimination of discrepancies between them Discrepancies may be due to di erences in representation models modeling perspectives or practices As instances of the semantic heterogeneity problem D Gangopadhyay and T Barsalou discrepancies are ...

Diorama artists produce a spectacular 3D effect in a confined space by generating depth illusions that are faithful to the ordering of the objects in a large real or imaginary scene. Indeed, cognitive scientists have discovered that depth perception is mostly affected by depth order and precedence among objects. Motivated by these findings, we employ ordinal cues to construct a model from a sin...

We present a featureless pose estimation method that, in contrast to current Perspective-n-Point (PnP) approaches, it does not require n point correspondences to obtain the camera pose, allowing for pose estimation from natural shapes that do not necessarily have distinguished features like corners or intersecting edges. Instead of using n correspondences (e.g. extracted with a feature detector...

Requirements analysis usually results into a set of different specifications for the same system, which must be integrated. Integration involves elimination of discrepancies completion and validation and proceeds in stages of analysis and synthesis. Realizing that discrepancies between specifications may be due to differences in representation models and/or modeling perspectives and practices, ...

Business modelling research is increasingly interested in exploring how domain ontologies can be used as reference models for business models. The Resource Event Agent (REA) ontology is a primary candidate for the ontology-driven modelling of business processes because the REA point of view on business reality is close to the conceptual modelling perspective on business models. In this paper On...

According to the OT error-driven ranking model of language acquisition, the learner performs a sequence of slight re-rankings triggered by mistakes on the incoming stream of data, until it converges to a ranking that makes no more mistakes. This learning model is very popular in the OT acquisition literature, in particular because it predicts a sequence of rankings that models gradualness in ch...

In this paper we explore the possibility of using a language action perspective to extend an analysis of organizational processes based on role activity diagramming (RAD). We have previously used role activity diagramming to show the large scale communication flows in an organizational domain and wanted to apply a language action approach to arrive at a finer level of detail for particular inte...
