User
-
specific requirements



Send complex queries to the portal and knowledge base



Which authors are most often mentioned regarding a specific topic?



The top five/ most relevant papers regarding a topic?



The most relevant conferences regarding a topic?



Who is engaged in a specific topic (pot. Community) ?



Adjoining communities?



(Semi
-
)automatic extraction of an implicitly given community profile



Bibster is knowledge base



Definition of a “rough” user profile



Automatic Community detection with Invitation

=> Portal Generation


=> Peer2Peer meets


Semantic Web Technology!!!

Approach

Community
-
Portal



How can the community
-
buildup be supported with semantic
web technologies?



Extraction of information from locally stored papers + Chat
+ extraction of information from web sites (Text
-
To
-
Onto?) +
publication lists/ team or staff descriptions



Semantic portal showing bibliographic information + links
to papers/ persons/ projects,



Usage logging
-
> Extraction of rules



Automatic genefration of additional information using pre
-
defined rules

Objective for One Day


Wrap one Peer behind a KAON portal


User friendly complex querying of the P2P
Network via the portal


Extract link between locally stored .pdfs
and locally stored Bibtex


Rank the most relevant Persons based on
the stored Papers


Rank the most relevant Papers based on
the stored Papers

Problems


Data integration


KAON labels


SWRC ontology in DAML


Properties in SWRC are not in RDFS


Virtual Integration in one day?


RDFS export of BIBSTER needs major
adaptation


Solution e.g.

grep "<rdfs:Class" $1 | gawk
-
F
\
" '{print $2}' | gawk
-
F
\
; '{print "<kaon:Label
rdf:ID=
\
""systime()"
-
c"NR"
\
"
\
nkaon:value=
\
""$2"
\
">
\
n<kaon:inLanguage
rdf:resource=
\
"&kaon;en
\
"/>
\
n <kaon:references
rdf:resource=
\
""$0"
\
"/>
\
n</kaon:Label>
\
n
\
n"}'grep "<rdf:Property" $1 | gawk
-
F
\
"
'{print $2}' | gawk
-
F
\
; '{print "<kaon:Label rdf:ID=
\
""systime()"
-
p"NR"
\
"
\
nkaon:value=
\
""$2"
\
">
\
n<kaon:inLanguage
rdf:resource=
\
"&kaon;en
\
"/>
\
n <kaon:references
rdf:resource=
\
""$0"
\
"/>
\
n</kaon:Label>
\
n
\
n"}'
