The velocity of digital information being produced everyday
continues to outpace efficient storage and processing capacities.
The volume of data that must be manipulated presents unique challenges
in algorithm design, and makes efficiently computing statistics, finding
interesting patterns, or answering queries difficult in many practical
settings. The Search Systems Group focuses on developing new
search, processing and storage models for complex data representations.
We are also interested in understanding how to measure the quality
of results returned in a variety of search and data analytics scenarios,
and ensure that the users' information needs are satisfied.
Many computational domains that are heavily reliant on the processing of
massive data collections, such as information retrieval, question answering,
dialog search, natural language processing, machine learning,
data mining, data science, bioinformatics, and data streams benefit
from this line of research.
