About the Edition

Declarative data quality has been an active research topic. The fundamental principle behind a declarative approach to data quality is the use of declarative statements to realize data quality primitives on top of any relational data source. A primary advantage of such an approach is the ease of use and integration with existing applications.Over the last couple of years several similarity predicates have been proposed for common quality primitives (approximate selections, joins, etc.) and have been fully expressed using declarative SQL staterrrents. In this thesis, new similarity predicates are proposed along with their declarative realization, based on notions of probabilistic information retrieval. Then, full declarative specifications of previously proposed similarity predicates in the literature are presented, grouped into classes according to their primary characteristics. Finally, a thorough performance and accuracy study comparing a large number of similarity predicates for data cleaning operations is performed.

  9 Examples of Functional Benchmarking posted by John Spacey, Ap Functional benchmarking is the practice of comparing results across diverse industries and processes using commonalities in functional capabilities. This is often done to compare results to an industry that achieves superior results in a particular area. The Community Foundation, sponsored by Boulder County, Colorado, publishes a Boulder County Trends Report on Key Indicators which leverages external benchmarking to provide context to the performance in Boulder County. Figure 5 is a snapshot of one page of the report, which emphasizes the county's desire to become more diverse.

  Attributes, Predicates, and Sentences: The Building Blocks of Context. Michel Prompt, CEO & Founder 1 Comment. We covered the key role of attributes in my last blogpost, moving from the blunter scope of groups and roles to the more fine-grained approach of attributes. Now we’re going to take this progression a step further, as we narrow in on. A predicate is a conditional expression that, combined with the logical operators AND and OR, makes up the set of conditions in a WHERE, HAVING, or ON clause. In SQL, a predicate that evaluates to UNKNOWN is interpreted as FALSE. A predicate that can exploit an index to retrieve rows from a table is called name comes from the phrase search argument-able.

Benchmarking declarative approximate selection predicates by Oktie Hassanzadeh Download PDF EPUB FB2

Several similarity predicates have been proposed in the past for common quality primitives (approximate selections, joins, etc.) and have been fully expressed using declarative SQL : Oktie Hassanzadeh.

we study declarative realizations of several similarity predicates for the popular approximate (flexible) selection operation for data de-duplication [17]. A similarity predicate is a predicate that numerically quantifies the “similarity” or “closeness” of two (string) tuples.

Given a. Fundamental to data cleaning is the need to account for multiple data representations. We propose a formal framework that can be used to reason about and manipulate data representations. The framework is declarative and combines elements of a generative grammar with database querying.

Abstract. In information integration systems, duplicate records bring problems in data processing and analysis. To represent the similarity between two records from different data sources with different schema, the optimal bipartite graph matching is adopted on the attributes of them and the similarity is measured as the weight of such by: 4.

Abstract. Given a large collection of objects, finding all pairs of similar objects, namely similarity join, is widely used to solve various problems in many application ation time of similarity join is critical issue, since similarity join requires computing similarity values for all possible pairs of l existing algorithms adopt prefix filtering to avoid Cited by: A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.
