Abstract

Lack of data and data quality issues are among the main bottlenecks that prevent further artificial intelligence adoption within many organizations, pushing data scientists to spend most of their time cleaning data before being able to answer analytical questions. Hence, there is a need for more effective and efficient data cleaning solutions, which, not surprisingly, is rife with theoretical and engineering problems. This report addresses the problem of performing holistic data cleaning incrementally, given a fixed rule set and an evolving categorical relational dataset acquired in sequential batches. To the best of our knowledge, our contributions compose the first incremental framework that cleans data (i) independently of user interventions, (ii) without requiring knowledge about the incoming dataset, such as the number of classes per attribute, and (iii) holistically, enabling multiple error types to be repaired simultaneously, and thus avoiding conflicting repairs. Extensive experiments show that our approach outperforms the competitors with respect to repair quality, execution time, and memory consumption., Comment: 29 pages, 13 figures

42. cx-Sim: A Metric Access Method for Similarity Queries with Additional Conditions

Abstract

The fast growth of complex data repositories, such as images, videos and time series, in recent years is intensifying the importance of developing efficient search strategies over these data types. Applications that deal with complex data employ similarity queries to retrieve data, often combining similarity conditions with conditions over other associated attributes of traditional data types. There are several indexing structures for answering similarity queries, however most of them do not work when there are additional search conditions. The existing structures that answer queries combining conditions over complex and traditional attributes only support keyword-based conditions. This article presents a new metric access method to efficiently execute similarity queries with additional conditions over complex data. The proposed method, called the Condition-eXtended Similarity tree (cx-Sim tree), is a composite index that is able to answer similarity queries with general conditions (not only keyword-based), combining an ordered tree to store a traditional attribute with a forest of similarity trees to store a complex attribute. The article also presents results of experiments using three real datasets that show that our approach outperformed existing methods in a great extent.
