We outline a call to action for promoting empiricism in data quality research. The action points result from an analysis of the landscape of data quality research. The landscape exhibits two dimensions of empiricism in data quality research relating to type of metrics and scope of method. Our study indicates ...

The Data Polygamy framework allows users to uncover interesting patterns and interactions in the data exhaust from different components of an urban environment. But analyzing the plethora of relationships derived by the framework is challenging. In this demo, we show how visualization can help in the discovery of relationships that ...

From tweets to urban data sets, there has been an explosion in the volume of textual data that is associated with both temporal and spatial components. Efficiently evaluating queries over these data is challenging. Previous approaches have focused on the spatial aspect. Some used separate indices for space and text, ...

Web sites have adopted a variety of adversarial techniques to prevent web crawlers from retrieving their content. While it is possible to simulate users behavior using a browser to crawl such sites, this approach is not scalable. Therefore, understanding existing adversarial techniques is important to design crawling strategies that can ...

We present ReproZip, the recommended packaging tool for the SIGMOD Reproducibility Review. ReproZip was designed to simplify the process of making an existing computational experiment reproducible across platforms, even when the experiment was put together without reproducibility in mind. The tool creates a self-contained package for an experiment by automatically ...

The analysis of provenance data for an experiment is often crucial to understand the achieved results. For long-running experiments or when provenance is captured at a low granularity, this analysis process can be overwhelming to the user due to the large volume of provenance data. In this paper we introduce, ...

Script languages are powerful tools for scientists. Scientists use them to process data, invoke programs, and link program outputs/inputs. During the life cycle of scientific experiments, scientists compose scripts, execute them, and perform analysis on the results. Depending on the results, they modify their script to get more data to ...

Collecting provenance from scripts is often useful for scientists to explain and reproduce their scientific experiments. However, most existing automatic approaches capture provenance at coarse-grain, for example, the trace of user-defined functions. These approaches lack information of variable dependencies. Without this information, users may struggle to identify which functions really ...

Focused crawlers are effective tools for applications requiring a high number of pages belonging to a specific topic. Several strategies for implementing these crawlers have been proposed in the literature, which aim to improve crawling efficiency by increasing the number of relevant pages retrieved while avoiding non-relevant pages. However, an ...

While much work has been devoted to understanding Web dynamics and using this knowledge to efficiently maintain the freshness of the indexes of generic search engines, the same is not true for domain-specific indexes constructed by focused crawlers. For the latter, the problem is compounded by the fact that it ...

As urban population grows, cities face many challenges related to transportation, resource consumption, and the environment. Ride sharing has been proposed as an effective approach to reduce traffic congestion, gasoline consumption, and pollution. Despite great promise, researchers and policy makers lack adequate tools to assess tradeoffs and benefits of various ...
