We present memory-based learning approaches to shallow parsing and apply these to five tasks: base noun phrase identification, arbitrary base phrase recognition, clause detection, noun phrase parsing and full parsing. We use feature selection techniques and system combination methods for improving the performance of the memory-based learner. Our approach is evaluated on standard data sets and t...

This paper presents CBRetaliate, an agent that combines Case-Based Reasoning (CBR) and Reinforcement Learning (RL) algorithms. Unlike most previous work where RL is used to improve accuracy in the action selection process, CBRetaliate uses CBR to allow RL to respond more quickly to changing conditions. CBRetaliate combines two key features: it uses a time window to compute similarity and stores...

Building a new GIS project is a major investment. Choosing the right GIS software package is critical to the success and failure of such investment. Because of the complexity of the problem a number of decision making tools must be deployed to arrive at the proper solution. In this study a new decision making approach for solving GIS software selection problem was proposed by integrating Expert...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

Selecting a suitable set of available software components for a component-based software system is a laborious task, often too complex to perform manually. We present a novel approach to automatic component selection that respects dependencies between the required components, an issue not considered by existing approaches. Our approach, which utilizes semantic technologies, is based on comprehe...

An agent-based model of population dynamics is presented. The model has as its expected behaviour the population dynamics of the equation-based Webworld model, within which large communities of species can be grown on evolutionary time scales. Such communities can be used in the agent-based model without disrupting the food web structure, and hence a unified model of evolutionary time and indiv...

In many informal social settings, disagreements about music choice can lead to conflict. Alternatively, some party attendees monopolize the music selection, subjecting everyone to their musical preferences. We present PartyVote, a democratic music voting system that provides both a traditional text based music selection system and a music library visualization to help users collaboratively choo...

Typical task in process design is to determine the configuration of a separation sequence. When dealing with multicomponent mixtures, the number of possible separation methods, their combinations and process structures to be screened is huge as well as the work involved. The method used, case-based reasoning (CBR), uses existing design cases stored in the database for solving new separation pro...
