ROMANIA Abstract: The goal of this paper is to present a new tool called HKS that is designed to help users to collect information about various concepts and their attributes from HTML pages. This version of the tool should facilitate the manual extraction of information from the visualized pages via a graphical user interface and the use of techniques like drag & drop and copy & paste. The ext...
Abstract In this paper, definitions of knowledge granulation and rough entropy are proposed based on dominance relations in incomplete fuzzy system (fuzzy information system), and important properties are obtained. It can be found that using the definitions can measure uncertainty of an attribute set in the incomplete fuzzy information systems. A matrix algorithm for attributes reduction is acq...
Diatoms are unicellular algae with plastids acquired by secondary endosymbiosis. They are responsible for approximately 20% of global carbon fixation. We report the 34 million-base pair draft nuclear genome of the marine diatom Thalassiosira pseudonana and its 129 thousand-base pair plastid and 44 thousand-base pair mitochondrial genomes. Sequence and optical restriction mapping revealed 24 dip...
This paper proposes an attribute clustering algorithm for grouping attributes into clusters so as to obtain meaningful modes from microarray data. First the problem of attribute clustering is analyzed and neighborhood mutual information is introduced to solve it. Furthermore, an attribute clustering algorithm is presented for grouping attributes into clusters through optimizing a criterion func...

E-mail address: [email protected] Class descriptors such as attributes, features or meronyms are rarely considered when developing ontologies. Even WordNet only includes a reduced amount of part-of relationships. However, these data are crucial for defining concepts su...
As the amount and types of remote network services increase, the analysis of their logs has become a very difficult and time consuming task. There are several ways to filter relevant information and provide a reduced log set for analysis, such as whitelisting and intrusion detection tools, but all of them require too much finetuning work and human expertise. Nowadays, researchers are evaluating...
Model transformations play a pivotal role in model-driven engineering. Since they are in many ways similar to traditional software artifacts, they have to be treated similarly. Therefore, it is necessary to assess their quality. We propose to use metrics to assess various quality attributes of model transformations In this paper, we focus on model transformations created using ATL, which ATL is...
Forest attributes such as tree heights, diameter distribution, volumes, and biomass can be modeled utilizing the relationship between remotely sensed metrics as predictor variables, and measurements of forest attributes on the ground. The quality of the models relies on the actual relationship between the forest attributes and the remotely sensed metrics. The processing of airborne laser scanni...
We describe a new knowledge acquisition tool that enabled us to develop a dialog system recommending software design patterns by asking critical questions. This assistance system is based on interviews with experts. For the interviews we adopted the repertory grid method and integrated formal concept analysis. The repertory grid method stimulates the generation of common and differentiating att...
The correlation between the performance of attributes and the overallsatisfaction such as they are perceived by the customers is often used tocalculate the importance of attributes in the crisp case. Recently, the methodwas extended, based on the standard Zadeh extension principle, to the fuzzycase, taking into account the specificity of the human thinking. Thedifficulties of calculation are im...
