چکیده

In this paper we describe an approach for spoken language analysis for helpdesk call routing using a combination of simple recurrent networks and support vector machines. In particular we examine this approach for its potential in a difficult spoken language classification task based on recorded operator assistance telephone utterances. We explore simple recurrent networks and support vector machines using a large, unique telecommunication corpus of spontaneous spoken language. The main contribution of the paper is a combination of techniques in the domain of call routing. First, we find that simple recurrent networks perform better than support vector machines for this task. Second, we claim that the combination of simple recurrent networks and support vector machines provides slightly improved performance compared to the performance of either simple recurrent networks or support vector machines.

Proposing a Novel Cost Sensitive Imbalanced Classification Method based on Hybrid of New Fuzzy Cost Assigning Approaches, Fuzzy Clustering and Evolutionary Algorithms

In this paper, a new hybrid methodology is introduced to design a cost-sensitive fuzzy rule-based classification system. A novel cost metric is proposed based on the combination of three different concepts: Entropy, Gini index and DKM criterion. In order to calculate the effective cost of patterns, a hybrid of fuzzy c-means clustering and particle swarm optimization algorithm is utilized. This ...
