Task Representation and Retrieval in an Ontology-Guided Modelling System

Yuan Ren, Jens Lemcke, Andreas Friesen, Tirdad Rahmani, Srdjan Zivkovic, Boris Gregorcic, Andreas Bartho, Yuting Zhao, Jeff Z. Pan
2009 International Semantic Web Conference  
In this paper, we present a novel approach which integrates task pre-and post-conditions into ontologies that describe the models, and infers availability of tasks through ontology reasoning and query  ...  We illustrate this approach with an application on process modelling and show how this can be generalised to other domains.  ...  The proper interpretation of task knowledge and its integration with meta-model/model is the major challenge of an ontology-guided modelling system. 4.  ...

A Concept-Based Approach for the Design of Web Usability Evaluation Questionnaires [chapter]

Elena García, Miguel A. Sicilia, León A. González, José R. Hilera
2003 Lecture Notes in Computer Science  
In this work, we describe a novel approach to design questionnaires that is based on a knowledge representation of the concepts involved in questionnaire-based usability evaluation.  ...  As a proof of concept of the model, a prototype has also been constructed, aimed at supplying a guided questionnaire development process especially useful for novel Web designers.  ...  In the basis of the previously selected elements, tasks that guide the participants are retrieved using the relationships among the terms of the functionality and task ontology.  ...

Case Based Reasoning: Case Representation Methodologies

Shaker H., Mohammed Elmogy
2015 International Journal of Advanced Computer Science and Applications  
It shows that ontology usage in case representation needs improvements to achieve semantic representation and semantic retrieval in CBR system.  ...  The first methods depend on ontology and enhance all CBR processes including case representation, retrieval, storage, and adaptation.  ...  This model describes CBR processes using tasks and methods (PSM). These tasks and methods have global CBROnto task/method hierarchies.  ...

A Context-Driven Software Comprehension Process Model

Wen Meng, Juergen Rilling, Yonggang Zhang, Rene Witte, Sudhir Mudur, Philippe Charland
2006 2006 Second International IEEE Workshop on Software Evolvability (SE'06)  
In this paper, we present a formal process model to support the comprehension of software systems by using Ontology and Description Logic.  ...  Comprehension is an essential part of software evolution. Only software that is well understood can evolve in a controlled manner.  ...  The ability to reason about information from the ontological representation to be able to provide an active and context sensitive support in guiding the comprehension process itself. 3.  ...

Considering Inter-Case Dependencies During Similarity-Based Retrieval in Process-Oriented Case-Based Reasoning

Rahol Kumar, Alexander Schultheis, Lukas Malburg, Maximilian Hoffmann, Ralph Bergmann
2022 Proceedings of the ... International Florida Artificial Intelligence Research Society Conference  
between cases, and, 3) present our approach for Dependency-Guided Retrieval (DGR) that considers these dependencies between cases during the retrieval phase.  ...  Therefore, we 1) derive requirements that must be satisfied for considering dependencies during the retrieval phase, 2) analyze which knowledge representations are suitable for representing dependencies  ...  The candidate representations are an OWL ontology and an XML document.  ...

Effective API navigation and reuse

Awny Alnusair, Tian Zhao, Eric Bodden
2010 2010 IEEE International Conference on Information Reuse & Integration  
Our approach is semantic-based; relying on an explicit ontological representation of sourcecode.  ...  We argue that such representation opens new doors for an improved recommendation mechanism that ensures relevancy and accuracy.  ...  However, since our graph is based on an ontology model, it is enriched with additional data that guides the search and helps us obtain more precise results.  ...

Camilo C. Almendra, Carla Silva, Vítor E. Silva Souza, Renata S. S. Guizzardi, César H. Bernabé
2019 International i* Workshop  
Knowledge-based systems are a good tool to assist analysts in carrying out such analysis. This work proposes an operational ontology to represent iStar 2.0 models using OWL-DL.  ...  In an early phase of software development, it is essential not to discard alternatives until some reasoning or evaluation is taken.  ...  z) SQWRL queries can filter and retrieve individuals in OWL ontologies [10] . The query is formed by an assertion over existing individuals, using SWRL syntax, and a select clause.  ...
