Researcher and CfP
Researchers spend a lot of time deleting dozens of useless CfPs from their email inboxes;
They spend even more time looking for relevant CfPs on the Web;
It is the very common situation when a researcher receives a word about an appropriate CfP a day after the submission deadline;
The Challenge: Semantically enhanced CfP
Can we target two opposite sides of the CfP publication process:
1. Solutions for semantic search, filtering and recommendation of CfPs should be designed for researchers;
2. Semantically rich tools and workflows for the dissemination of CfPs targeted at CfP providers;
State of the Art: Where CfPs are now?
Mailing Lists and Blogs;
Web Based Services;
Adding Semantics to HTML;
Parsing Plain CfP Data;
CfP Related Representation Frameworks
Mailing Lists and Blogs
Mailing lists’ examples:
dbworld
AISWorld
Not very efficient solution in terms of filtering data or semantic search;
Ability of blogs to provide the semantic meaning for posts is limited by the RSS vocabulary
Web Based Services
Try to implement a semantic approach to processing the CfP data:
WikiCFP;
eventseer.net;
Conference Alerts;
PapersInvited;
AllConferences.Com;
etc;
Use HTML with no semantic markup;
Limited, not compatible vocabularies
Adding Semantics to HTML
Technologies that support applying semantics to HTML:
Microformats – has very limited vocabulary;
RDFa – not a clear prospect after end of XHTML2;
Microdata – a new player, almost isn’t used at all, no web browser supports microdata at the moment
Parsing Plain CfP Data
The first attempts were conducted in 1989;
Limitations:
Absence of unified CfP vocabulary;
Complex, multi-level structures of CfPs;
Continuously extended types of data used in CfPs do not allow for overall data extraction
CfP Related Representation Frameworks
CfP vocabulary;
LODE – Linking Open Descriptions of Events;
ESWC2006 Conference Ontology;
AKT Portal;
SWRC – Semantic Web for Research Communities;
SWPortal – Semantic Web Portal;
SwetoDblp;
SEDE – Scholarly Event Description Ontology
Findings in Analysis of Existing CfP Practices
Difference between the original CfPs and their analogues in WikiCFP – based on vocabulary web-form scaffolds event organizers to provide information in more standardised manner;
We found that all used concepts can be categorised into six groups: Events, Places, Submissions, Publications, Dates, and People
DESIGNING THE CALL ONTOLOGY
Call ontology: concepts for Events
Call ontology: concepts for Submissions
Call ontology: concepts for Dates
Call ontology: concepts for Publications
Call ontology: concepts for People and Organizations
Two Usage Scenarios for Call Ontology
1. Timeliner – a tool for supporting collaborative scientific writing;
2. Novel conference management system ginkgo
Timeliner
Timeliner – concept of a mash-up tool supporting the orchestration of collaborative writing process;
Timeliner aggregates CfP-related data into a joint multi-level timeline inspired by Gantt chart
If CfP is accepted by user, all related deadlines (submission, acceptance, registration etc) and links to resources are placed on the timeline.
Layered Timeliner architecture
Ginkgo – Modern Conference Management System
ginkgo supports Research 2.0 practices with all the phases and roles involved in the organization of events;
ginkgo could apply the Call ontology presented here together with an easy-to-use editor;
ginkgo would provide a SPARQL endpoint where crawler could access all available CfPs of events managed with the system
Future Challenges
The existing conference management systems should be examined for the purpose of services integration;
Design of a service capable of aggregating and making use of semantic-rich CfP data generated by conference management systems. This service should:
1. Consume advertised CfPs;
2. Provide a structured and personalized access to such data for researchers
