Sommario/riassunto |
|
Written for practitioners of data mining, data cleaning and database management. Presents a technical treatment of data quality including process, metrics, tools and algorithms.Focuses on developing an evolving modeling strategy through an iterative data exploration loop and incorporation of domain knowledge.Addresses methods of detecting, quantifying and correcting data quality issues that can have a significant impact on findings and decisions, using commercially available tools as well as new algorithmic approaches.Uses case studies to illustrate applications in real |

Sommario/riassunto |
|
The chapters in this volume focus on how we might understand the concept of 'unit' in human languages. It is an analytical notion that has been widely adopted by linguists of various theoretical and applied orientations but has recently been critically examined by both typologically oriented and interactional linguistics. |
