<BODY>Dear Prof.Nesterenko,<BR><BR>I have sent my presentation topic to your cs
account, which listed on the website as <A
href="mailto:mikhail@cs.kent.edu">mikhail@cs.kent.edu</A>, last Friday.
Therefore I really hope you won't take half a grade from my final grade please.
I attached the original email
below.<BR><BR>----------------------------------------------------------------------------------------------------------------------------------<BR><BR>Dear
Prof. Nesterenko, <BR><BR>The topic I want to talk about is semantic
search, especially focus on a recently published paper called "gStore: Answering
SPARQL Queries via Subgraph Matching". I will also mention the basic concepts of
RDF, SPARQL as well as previous important semantic search engines. And I
prefer to do it in November if possible please.<BR><BR>Abstract:<BR><BR>Due to
the increasing use of RDF data, efficient processing of SPARQL<BR>queries over
RDF datasets has become an important issue.<BR>However, existing solutions
suffer from two limitations: 1) they<BR>cannot answer SPARQL queries with
wildcards in a scalable manner;<BR>and 2) they cannot handle frequent updates in
RDF repositories<BR>efficiently. Thus, most of them have to reprocess the
dataset from<BR>scratch. In this paper, we propose a graph-based approach to
store<BR>and query RDF data. Rather than mapping RDF triples into a
relational<BR>database as most existing methods do, we store RDF data<BR>as a
large graph. A SPARQL query is then converted into a corresponding<BR>subgraph
matching query. In order to speed up query<BR>processing, we develop a novel
index, together with some effective<BR>pruning rules and efficient search
algorithms. Our method can<BR>answer exact SPARQL queries and queries with
wildcards in a uniform<BR>manner. We also propose an effective maintenance
algorithm<BR>to handle online updates over RDF repositories. Extensive
experiments<BR>confirm the efficiency and effectiveness of our
solution.<BR><BR>BTW. above is the abstract of the paper, should I also give you
a separete abstract for my talk specifically please?<BR><BR>Thanks for your
time.<BR>Sincerely, <BR>Guan Wang <BR>2011-09-30

<BR>Content-Type: text/plain; charset=us-ascii <BR><BR>Seminar students,
<BR><BR>I put up a list of presentation topics for the students who contacted
<BR>me on the course's webpage. I'll try to do the scheduling of your
<BR>presentation this week. <BR><BR>If you have not contacted me by now about
either selecting a pass/fail <BR>option or about the topic of your presentation,
half a grade will be <BR>subtracted from your final grade. You need to give me
the topic of <BR>your presentation as soon as possible. Those, whom I asked
<BR>clarification questions, you need to answer right away. <BR><BR>For those
students asking for a presentation topic, I suggest going to <BR>one of our
faculty's research webpages and selecting a paper to <BR>present. For example, a
list of my papers is available here:
