% OBJECTIVES
%----------------------------------------------------------------------------------------
\begin{alertblock}{Objectives}
\begin{itemize}
\item To discover \textbf{effective latent concepts} for query
expansion from from manually and automatically constructed concept graphs (or semantic networks), in which the nodes correspond to words
or phrases and the typed edges designate semantic relationships between words and phrases.
\item To leverage \textbf{large and dense concept graphs}, in which the number of candidate concepts that
are related to query terms and phrases and need to be examined increases exponentially with the distance from the
original query concepts.
\end{itemize}
\end{alertblock}

\end{itemize}
\end{block}
\begin{block}{Approximate Solution}
\begin{enumerate}
\item The candidate
concepts are \textbf{sorted} using computationally \textbf{inexpensive features}.
\item This sorting is utilized in the \textbf{second stage} to sequentially \textbf{select expansion concepts} by using computationally \textbf{expensive
features}.

% CONCLUSION
%----------------------------------------------------------------------------------------
\begin{block}{Conclusion}
The main contribution of this work is a two-stage method
for sequential selection of effective concepts for query expansion from the concept graph. The proposed method is formulated as an optimization problem with the goal of evaluating the least possible number of candidate concepts needed
to ensure a given precision of retrieval results.
