Advantage of Integration in Big Data: Feature Generation in Multi-Relational Databases for Imbalanced Learning
DownloadFall 2016
Most data mining and machine learning techniques rely on a single flat table and assume balanced training data. However, most real-world applications comprise databases having multiple tables and imbalanced data. It becomes further complicated in the realm of Big Data where related information is...

An Exploration of Dialog Act Classification in Open-domain Conversational Agents and the Applicability of Text Data Augmentation
DownloadFall 2023
Recognizing dialog acts of users is an essential component in building successful conversational agents. In this work, we propose a dialog act (DA) classifier for two of our open domain conversational agents. For this, we curated a high-quality, multi-domain dataset with ∼24k user utterances...

An Interaction-driven Approach for Inferring the Polarity of Collaborations in Wikipedia and Political Preferences on Twitter
DownloadSpring 2013
In this thesis we explore interactions of users of two major information sources, namely Wikipedia and Twitter. In particular, we show that revision histories of Wikipedia articles contain interaction patterns which can be used to build collaboration profiles of editors. Such profiles can be...

Spring 2016
While the World Wide Web has always been treated as an immense source of data, most information it provides is usually deemed unstructured and sometimes ambiguous, which in turn makes it unreliable. But the web also contains a relatively large number of structured data in the form of tables,...

Fall 2014
We study the problem of classifying users in a classified ad network and its applications in further analyzing the network. Specifically, we seek to classify Kijiji users into one of the two business and non-business categories. The problem is challenging due to the sparsity of the data about...
