background :  sequence-based identification of various microorganisms including archaea, bacteria, cyanobacteria, diatoms, fungi, and green algae necessitates an efficient and reproducible genome extraction procedure though which a pure template dna is yielded and it can be used in polymerase chain reactions (pcr). considering the fact that dna extraction from these microorganisms is time consu...

Among the huge number of attributes or features present in real-life data sets, only a small fraction of them are effective to represent the data set accurately. Prior to analysis of the data set, selecting or extracting relevant and significant features is an important preprocessing step used for pattern recognition, data mining, and machine learning. In this regard, a novel dimensionality red...

In this research, we have compared three different attribute selection measures algorithms. We have used ID3 algorithm, C4.5 algorithm and CART algorithm. All these algorithms are decision tree based algorithm. We have got the accuracy of three different algorithms and we observed that the accuracy of ID3 algorithm is greater than C4.5 algorithm. But the accuracy of CART algorithm is greater th...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

The Web has become the most major information source of our daily activities. In this project, we consider a special information need: finding the instance-attribute information from the Web, and particularly, we focus on the instance domain of person. Examples include the contact information (attribute) and research interests (attribute) of faculty or students (person). Most of such personal i...

In this paper, we study the problems of opinion expression extraction and expression-level polarity and intensity classification. Traditional fine-grained opinion analysis systems address these problems in isolation and thus cannot capture interactions among the textual spans of opinion expressions and their opinion-related properties. We present two types of joint approaches that can account f...
