Information Retrieval Literature

Here are lists of major information retrieval conferences, journals, and databases where you can nd good literature in related areas. Among these venues, the SIGIR conference (special interest group on information retrieval) and ACM TOIS (Transactions on Information Systems) are two of the highly regarded. Most of these can be accessed through:

Large-scale and distributed information retrieval

The goal was to investigate basic principles underlying efficient and effective search operations given the magnitude of information (big data) and distributed computing resources (cloud). I developed the theory of clustering paradox in distributed IR and studied its impacts on searching in large-scale information networks (see representative publication to appear in ACM TOIS 2013).

Scatter/Gather browser on a news collection

We implemented a Scatter/Gather browser using 33k news documents provided by HARD track from the Text REtrieval Conference (TREC). Scatter/Gather provides a different approach (from classic paradigms of searching and browsing) to finding information and is often useful in situations where the user may feel difficult to formulate a search query. The included image is a snapshot a working/demo system, which can be accessed at:
