[msseminar] About my topic, I sent it to you on last Firday

[Guan Wang]

Dear Prof.Nesterenko,

I have sent my presentation topic to your cs account, which listed on the website as mikhail at cs.kent.edu, last Friday. Therefore I really hope you won't take half a grade from my final grade please. I attached the original email below.

Dear Prof. Nesterenko, 

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.

Abstract:

Due to the increasing use of RDF data, efficient processing of SPARQL
queries over RDF datasets has become an important issue.
However, existing solutions suffer from two limitations: 1) they
cannot answer SPARQL queries with wildcards in a scalable manner;
and 2) they cannot handle frequent updates in RDF repositories
efficiently. Thus, most of them have to reprocess the dataset from
scratch. In this paper, we propose a graph-based approach to store
and query RDF data. Rather than mapping RDF triples into a relational
database as most existing methods do, we store RDF data
as a large graph. A SPARQL query is then converted into a corresponding
subgraph matching query. In order to speed up query
processing, we develop a novel index, together with some effective
pruning rules and efficient search algorithms. Our method can
answer exact SPARQL queries and queries with wildcards in a uniform
manner. We also propose an effective maintenance algorithm
to handle online updates over RDF repositories. Extensive experiments
confirm the efficiency and effectiveness of our solution.

BTW. above is the abstract of the paper, should I also give you a separete abstract for my talk specifically please?

Thanks for your time.
Sincerely, 
Guan Wang

Seminar students, 

I put up a list of presentation topics for the students who contacted 
me on the course's webpage. I'll try to do the scheduling of your 
presentation this week. 

If you have not contacted me by now about either selecting a pass/fail 
option or about the topic of your presentation, half a grade will be 
subtracted from your final grade. You need to give me the topic of 
your presentation as soon as possible. Those, whom I asked 
clarification questions, you need to answer right away. 

For those students asking for a presentation topic, I suggest going to 
one of our faculty's research webpages and selecting a paper to 
present. For example, a list of my papers is available here:

Thanks,

Mikhail
