Soft Co-Occurrence Clustering for Natural Language Understanding

Liaison: Frank Elliott
Advisor: Christine Alvarado
Students: Stephen Jones (PM), Christopher Kain, George Tucker, Craig Weidert

Co-clustering is a statistical technique that groups objects that share similar features. It has applications in many fields, including natural language processing. Current co-clustering algorithms limit each item to one cluster, but in many cases items fall naturally into more than one cluster (e.g. the word “may” in natural language processing). The team used a Dirichlet mixture model to implement “soft” co-clustering, assigning each item a probability of being in each cluster.

Laserfiche

Improved Photo-Document Segmentation

Liaisons: Karl Chan ’87, Ed Heaney ’04, Kurt Rapelje
Advisor: Zachary Dodds
Students: Adam Field, Stephen Smith, Benjamin Tribelhorn (PM), Aaron Wolin

This project seeks to replace a document scanner with a hand-held digital camera as a front-end to Laserfiche’s document-management solutions. Conditions such as shadows, indistinct backgrounds, multiple documents, and occlusions make it difficult to determine the document’s location within the camera’s image: this is the segmentation problem. The team has integrated pixel-level, edge-level, and structural-level image processing routines within a probabilistic framework to find appropriate document segmentation in a variety of business cases.
