retrieves a fixed number (top K) of relevant pages
-- compute TF/IDF
-- extraction of Named entities (NEs)
and Web-related information
the entity-relationship (ER) graph
(3)web page ranking
Overview of the approach(3/3)
focus on developing and learning a new
c(u,v) can help designing a better similarity function s(u,v)
s(u,v) lebals data with the threshold τ and the δ-band approach
-用來計算 feature-based similarity f(u,v)
The value of w-（ ）is chosen to be zero when is less than a certain threshold, and it is chosen to be 1 when it is above this threshold. The value for this threshold itself is learned from the data.
The remainder pages are displayed in the order of the affinity to the selected cluster.

2.middleware approach （ˇ）
Testing disambiguation quality—Experiment 1 （disambiguation quality : overall）
Testing disambiguation quality— Experiment 2 （disambiguation quality :group identification）
Testing disambiguation quality— Experiment 3 （disambiguation quality :queries with context）
Testing disambiguation quality— Experiment 4 （ quality of generating cluster sketches）
1.由於透過第三者 (NE extractor, GATE) 摘錄NEs， 一開始的下載及前處理，每個網頁需要用3.82秒。
2.假如用 server-side approach, 前處理過程就可以離線事先做好。
