Checking UML and OCL Model Behavior with Filmstripping and Classifying Terms

open access: closed, 2017
This tool paper discusses how model behavior expressed in a UML and OCL model can be analysed with filmstrips and classifying terms in the tool USE. Classifying terms are a means for systematic construction of test cases. In the case of behavior models these test cases correspond to testing the model with different sequence diagrams.

Classifying Class and Finding Community in UML Metamodel Network

open access: closed, 2005
Composed of many classes or modules, big software can be represented with network model. By extracting the topology of UML metamodel from the UML metamodel specification, the scale-free, small-world networks properties are revealed. Based on this observation, we come up with our algorithms that can classify all classes in UML metamodel into three kinds:

Constraining Type Parameters of UML 2 Templates with Substitutable Classifiers

open access: closed, 2009
Generic programming is a field of computer science which consists in defining abstract and reusable representations of efficient data structures and algorithms. In popular imperative languages, it is usually supported by a template-like notation, where generic elements are represented by templates exposing formal parameters.

Using distributional analysis to semantically classify UMLS concepts.

open access: closedStudies in health technology and informatics, 2007
The UMLS is a widely used and comprehensive knowledge source in the biomedical domain. It specifies biomedical concepts and their semantic categories, and therefore is valuable for Natural Language Processing (NLP) and other knowledge-based systems. However, the UMLS semantic classification is not always accurate, which adversely affects performance of

Combining contextual and lexical features to classify UMLS concepts.

AMIA ... Annual Symposium proceedings. AMIA Symposium, 2008
Semantic classification is important for biomedical terminologies and the many applications that depend on them. Previously we developed two classifiers for 8 broad clinically relevant classes to reclassify and validate UMLS concepts. We found them to be complementary, and then combined them using a manual approach.
