Semantic enriched search

The abundance of resources on the Internet has imposed challenges to users¡¦ information access. Self-Organizing Maps (SOM) provide a novel navigation method to respond to users¡¦ diverse requirements.However, as an increasing number of studies have adopted SOM as their representation methods, the quality of these methods becomes critical to determine whether users are receiving high-quality navigation assistance/information. Therefore, I am studying the improvement of SOM representation quality by integrating various semantic features.

Exploratory Search

Nowadays, users not only look up answers on the Internet but also learn and live with the Web. Exploratory search provides broader information support while users are seeking information online. We were trying to build and support exploratory search in the ¡§Teenie¡¨ Harris Archive from the Carnegie Museum of Art. Named-entity based faceted browsing was proposed to achieve the goal.

How could we provide useful resources to different students with different learning backgrounds and progresses? We are trying to detect relevant resources and also novel material to our students.
