- Hierarchical online text
classification for real-time problem classification in large-scale
distributed technical support services. Comparing to the traditional
batch learning algorithms, this online learning framework can
significantly decrease the computational complexity of the training
process by learning from new instances on an incremental fashion. In the
same time this reduces the amount of memory required to store the
training instances.

- Large-scale text classification with application to email spam
filtering. Proposed a novel two-level cascaded Naive Bayes
model. The model was further augmented by collaborative filtering to
improve the performance. Results on Hotmail data shows substantial
improvement against previous methods.

- Co-designed
and improved real-time on-line entity extraction algorithms, designed
and implemented three demo systems that may eventually lead to
product(s) on the live site. The algorithms showed better running time,
as well as better precision and recall, compared to some of the current
wildly-used extraction algorithms. The demo systems involved processing
of both unstructured and semi-structured data, including entity extraction
from generic HTML pages.
