Refining Goal Models by Evaluating System Behaviour
Nowadays information systems have to perform in complex, heterogeneous environments, considering a variety of system users with different needs and preferences. Software engineering methodologies need to cope with the complexity of requirements specification in such scenarios, where new requirements may emerge also at run-time and the system’s goals are expected to evolve to meet new stakeholde...
متن کاملRefining Generative Language Models using Discriminative Learning
We propose a new approach to language modeling which utilizes discriminative learning methods. Our approach is an iterative one: starting with an initial language model, in each iteration we generate 'false' sentences from the current model, and then train a classifier to discriminate between them and sentences from the training corpus. To the extent that this succeeds, the classifier is incorp...
متن کاملBuilding and Refining Rhetorical-Semantic Relation Models
We report results of experiments which build and refine models of rhetoricalsemantic relations such as Cause and Contrast. We adopt the approach of Marcu and Echihabi (2002), using a small set of patterns to build relation models, and extend their work by refining the training and classification process using parameter optimization, topic segmentation and syntactic parsing. Using human-annotate...
متن کاملRefining internal choice in PEPA models
In a previous paper [GHH96] the authors presented a program development technique for stochastic process algebra models which was centred on the translation from a model into an abstract program skeleton which presents the structural and behavioural information from the model in programming language notation. The intention of this work, which we continue here, is to support the methodical devel...
متن کاملRefining Building Facade Models with Images
Laser data and optical data have a complementary nature to 3D features’ extraction. Building reconstruction by fusion of the two data sources can reduce the complexity of approaches from either side. In this paper we present a model refinement method, which uses the strong lines extracted from close-range images to improve building models reconstructed from terrestrial laser point clouds. First...
