There are numerous applications (e.g., video surveillance, fraud detection, cybersecurity) in which we wish to identify unexplained sets of events. Most related past work has been domain-dependent (e.g., video surveillance, cybersecurity) and has focused on the valuable class of statistical anomalies in which statistically unusual events are considered. In contrast, ...

There are numerous applications where we wish to discover unexpected activities in a sequence of time-stamped observation data--for instance, we may want to detect inexplicable events in transactions at a website or in video of an airport tarmac. In this paper, we start with a known set $({\cal A})$ of ...

Though subgraph matching has been extensively studied as a query paradigm in semantic web and social network data environments, a user can get a large number of answers in response to a query. Just like Google does, these answers can be shown to the user in accordance with an importance ...

Most real-world databases have at least some missing data. Today, users of such databases are “on their own” in terms of how they manage this incompleteness. In this paper, we propose the general concept of partial information policy (PIP) operator to handle incompleteness in relational databases. PIP operators build upon ...

This SpringerBrief proposes a general framework for reasoning about inconsistency in a wide variety of logics, including inconsistency resolution methods that have not yet been studied. The proposed framework allows users to specify preferences on how to resolve inconsistency when there are multiple ways to do so. This empowers users ...
