Reports Summarize Database Management Study Results from Stanford University

March 4, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Researchers detail new data in Database Management. According to news reporting out of Stanford, California, by VerticalNews editors, research stated, "Entity resolution (ER) identifies database records that refer to the same real-world entity. In practice, ER is not a one-time process, but is constantly improved as the data, schema and application are better understood."

Our news journalists obtained a quote from the research from Stanford University, "We first address the problem of keeping the ER result up-to-date when the ER logic or data 'evolve' frequently. A na < ve approach that re-runs ER from scratch may not be tolerable for resolving large datasets. This paper investigates when and how we can instead exploit previous 'materialized' ER results to save redundant work with evolved logic and data. We introduce algorithm properties that facilitate evolution, and we propose efficient rule and data evolution techniques for three ER models: match-based clustering (records are clustered based on Boolean matching information), distance-based clustering (records are clustered based on relative distances), and pairs ER (the pairs of matching records are identified)."

According to the news editors, the research concluded: "Using real datasets, we illustrate the cost of materializations and the potential gains of evolution over the na < ve approach."
