When dealing with real-world data, dirty data is the norm rather than the exception. We continuously need to predict correct values, impute missing ones, and find links between various data artefacts such as schemas and records. We need to stop treating data cleaning as a piecemeal exercise (resolving different types of errors in isolation), and […]

Graph Pattern Matching Queries – Approximation and User-Friendliness
Graphs are a ubiquitous model to represent objects and their relations. Examples include communication and computer systems, the World Wide Web, online social networks, biological networks, transportation systems, epidemic networks, chemical networks, and hidden terrorist networks. All these systems can be modeled as graphs, in which individual components interact with a specific set of components, […]
