Projects

Geography Query Parsing (CLEF Geographical Information Retrieval Track)

• Geography name entity identification. Extracting geography names entity with corresponding from Wikipedia.
• Geography name entity disambiguation. Designing components to disambiguate locations by estimating the distance between two locations and geography context information.
• Query type identification. Classifying the query type by identifying the nearest-neighbor nodes in semantic knowledge networks.

Collaborative Filtering Search System (NSF)

• Mining the data from Citeulike for system training and evaluations.

Toward Classify Exploratory Search Results with Wikipedia (Prelim Exam)

• Classifying exploratory search results to support people for Request For Information (RFI) search task.
• Identifying the potential concepts in search queries using Wikipedia entries, and evaluating the effectiveness of the approach
• Demonstrating the possibility of using Wikipedia articles as training data sets to help classification task. And concluding some rules for collecting training data sets for this task.

GALE Project

• Passage-level precision recall evaluation
• Continuing and completing the passage-level precision and recall evaluation tool component. This tool is Java-based with inputs of snippets and outputs of passage-level precision.
• Implementing the algorithm for combining two annotators evaluations for the ground truth.
• More information welcome to our Gale Project Website

Design and Implementation Tools for Object-Oriented Design Flaws Detection (Master Degree Thesis)

• Studyed on the detections of Object-Oriented (OO) Design Flaws, using metrics to quantitize the quality of the OO softwares.
• Reviewed metrics for detecting OO design flaws and proposed metric framework for OO Design Flaws according to the Goal-Driven Measurement Process.
• Implemented Java-based tool sets, providing basic object-oriented statistics data of Jave scripts and predicting the potential design flaws according to the framework I proposed for users.
