Optimizing interactive information retrieval interfaces is a new trend in IR which focuses more on the interface design and formalizes interactive IR. However, none of existing work has proposed a system to support both ...

A lot of digital ink has been spilled on "big data" over the past few years, which is often characterized by an explosion of information. Most of this surge owes its origin to the unstructured data in the wild like words, ...

This thesis describes the design and implementation of the Database module in a novel Cloud-based Open Lab for Data Science (COLDS) system. COLDS is a general infrastructure system to support data science programming ...

This thesis describes the design and implementation of the search engine module in a novel Cloud-based Open Lab for Data Science (COLDS) system. COLDS is a general infrastructure system to support data science programming ...

The rapid development of modern information technology has significantly facilitated the generation, collection, transmission and storage of all kinds of data. With the so-called “big data” generated in an unprecedented ...

An unprecedented development of various kinds of social media platforms, such as Twitter, Facebook and Foursquare, has been witnessed in recent years. This huge amount of user generated data are multi-dimensional in nature. ...

I conduct a systematic study of probabilistic latent variable models (PLVMs) with applications to knowledge discovery and optimization. Probabilistic modeling is a principled means to gain insight of data. By assuming that ...

A large portion of real world data is either text or structured (\eg, relational) data. Such data objects are often linked together (\eg, structured product information linking with their descriptions and customer reviews.). ...
