Discovering and Selecting Valuable Sources for Integration


Data is becoming a commodity of tremendous value for many domains. This is leading to a rapid increase in the number of autonomous data sources, which exhibit wide variety and heterogeneity in the types of the data they provide, their quality, and the cost of accessing their data. Users who want to build upon such data, must (i) discover sources that are relevant to their applications, (ii) identify sources that collectively satisfy the quality and budget requirements of their applications, with few effective clues about the quality of the sources, and (iii) repeatedly invest many person-hours in assessing the eventual usefulness of data sources. All three steps require investigating the content of the sources manually, integrating them and evaluating the actual benefit of the integration result for a desired application. Unfortunately, when the number of data sources is large, humans have a limited capability of reasoning about the actual quality of sources and the trade-offs between the benefits and costs of acquiring and integrating sources. In this talk, we focus on the problems of automatically appraising the quality of data sources and identifying the most valuable sources for diverse applications.
