A practical web-based approach to generating topic hierarchy for text segments

Shui-Lung Chuang, Lee-Feng Chien
2004 Proceedings of the Thirteenth ACM conference on Information and knowledge management - CIKM '04  
In this paper, we address the problem of generating topic hierarchies for diverse text segments with a general and practical approach that uses the Web as an additional knowledge source.  ...  Different from traditional clustering algorithms, which tend to produce cluster hierarchies with a very unnatural shape, the approach tries to produce a more natural and comprehensive hierarchy.  ...  In this paper, we address the problem of generating topic hierarchies for diverse text segments, and present a practical approach that deals with the problem using the Web as an additional knowledge source  ...

A Lightweight Coordination Approach For Resource-Centric Collaborations [chapter]

Morteza Ghandehari, Eleni Stroulia
2013 REST: Advanced Research Topics and Practical Applications  
To meet the need for flexibly coordinating people, interactive tools, and automated services, we have developed a coordination approach and a supporting framework.  ...  All these types of collaborative work share a few key properties. They usually involve a variety of interactive tools.  ...  I would also like to thank my colleagues in GRAND and CWRC projects who helped me a lot in this thesis.  ...

A practical approach to hypothetical database queries [chapter]

Henning Christiansen, Troels Andreasen
1998 Lecture Notes in Computer Science  
Thus the answer to a hypothetical query h > q, with a hypothesis h, is in principle the result of evaluating q against the database revised with h.  ...  In case h is inconsistent with the database, query evaluation becomes a special case of counterfactual reasoning.  ...  The restriction to examining a single world together with an efficient evaluator makes our approach appropriate for practical database application, which is certainly not the case for any treatment of  ...

Consumption Practices: A Virtue Ethics Approach

Pablo Garcia-Ruiz, Carlos Rodriguez-Lluesma
2014 Business Ethics Quarterly  
We build on MacIntyre's goods-virtues-practices-institutions framework and Beabout's concept of a domain-relative practice and argue that when engaging in consumption activities, agents may pursue goods  ...  This paper proposes virtue ethics as a more apt conceptual framework for the ethical analysis of consumption because it takes into account the developmental dynamic triggered by engagement in consumption  ...  A third advantage of our approach is a practical one. Virtue ethics is an apt approach to induce people to consume moderately, thereby fostering human and environmental flourishing.  ...

Gastrointestinal lymphoproliferative lesions: a practical diagnostic approach

Marco Pizzi, Elena Sabattini, Paola Parente, Alberto Bellan, Claudio Doglioni, Stefano Lazzi
2020 Pathologica  
To reach to confident conclusions, a stepwise approach is highly recommended. Histological evaluation should first assess the benign versus neoplastic nature of a given lymphoid infiltrate.  ...  The diagnosis of these diseases is challenging and an integrated approach based on clinical, morphological, immunohistochemical and molecular data is needed.  ...  A practical approach will be followed, by grouping GI LPDs into major diagnostic categories, discussing their general features and considering their differential diagnosis.  ...

A practical approach to dialogue response generation in closed domains [article]

Yichao Lu, Phillip Keung, Shaonan Zhang, Jason Sun, Vikas Bhardwaj
2017 arXiv   pre-print
We show that, in a closed domain like customer service, the selected templates cover $>$70\% of past customer inquiries.  ...  Furthermore, the relevance of the model-selected templates is significantly higher than templates selected by a standard tf-idf baseline.  ...  We would also like to thank the customer service associates who helped us evaluate our system and provided domain-specific feedback on its design.  ...

Furthermore, by applying such a structured modeling approach, we were able to reveal several issues in the original requirements specifications.  ...  To achieve this, we performed a case study, in which we created models for requirements and functionality for a part of a Siemens train automation system.  ...  However, evaluating how well the approach performs, when used with the requirements specification of a productive system would be a major step towards introducing the approach into industrial practice.  ...
