OKBQA 2017

The OKBQA 2017 has successfully finished. We would like to thank everyone who attended.

Introduction

The huge and rapidly increasing amount of structured and unstructured data available on the Web makes it both possible and necessary to support users in finding relevant information. The trend moves more and more towards smart knowledge services that are able to find information, aggregate them, draw inferences, and present succinct answers without requiring the user to wade through a large number of documents. The novel avenues made possible by knowledge services are numerous and diverse, including ubiquitous information access (from smartphones, tablets, smart watches, etc.), barrier-free access to data (especially for the blind and disabled) and knowledge discovery.

Over the last years, several challenges and calls for research projects have pointed out the dire need for pushing natural language interfaces. In this context, the importance of Semantic Web data as a premier knowledge source is rapidly increasing. But we are still far from having accurate natural language interfaces that allow handling complex information needs in a user-centric and highly performant manner. The development of such interfaces requires the collaboration of a range of different fields, including natural language processing, information extraction, knowledge base construction and population, reasoning, and question answering.

The main goal of this workshop is to join forces in the collaborative development of open frameworks for knowledge extraction and question answering, to share standards, and to foster the creation of an ecosystem of tools and benchmarks. The workshop will therefore not only comprise short and long paper presentations but also a hands-on session on already existing frameworks, standards, and benchmarking campaigns, as well as a social meet-up.

Paper Submissions

OKBQA 2017 solicits the submission of original research papers in two types:

• Full paper submissions (up to 8 pages, plus two extra pages for references) must describe substantial and original work.
• Short paper submissions (up to 4 pages, plus two extra pages for references) must describe an original work which may present a small, focused contribution, a work in progress, or an interesting application case.

Please use the ACM proceedings style file http://www.acm.org/publications/proceedings-template
It has L^aT_eX files, Microsoft Word templeate file, and a sample PDF file.

Before submitting your paper please ensure you have read the Instructions for Authors and that your paper uses the prescribed style files. To submit your work, please use the submission page at the following Easychair address https://easychair.org/conferences/?conf=okbqa2017.

At least one author of each paper is expected to register for the workshop and attend to present the paper.

Demo Submissions

The OKBQA2017 workshop, to be held in Tokyo, 11th August, invites proposals for system demonstrations. Submissions may range from early prototypes to mature production-ready systems. Areas of interest include all topics related to KB construction and QA. Please refer to the workshop page for a full lists topics of interest.

Submission Deadline: 5, July 2017

A proposal may be an extended abstract upto two pages including references, and is expected to include:

• summary of the system with an emphasis on innovative features,
• reference to published papers, if any,
• URL of a working system, if any,
• URL of screencast, if any,
• URL of project page, e.g., GitHub project, if any

Note that a proposal should deliver sufficient details about the system to allow evaluation of its quality, relevance to the workshop, and so on.

Please use the ACM proceedings style file http://www.acm.org/publications/proceedings-template
It has L^aT_eX files, Microsoft Word templeate file, and a sample PDF file.

Before submitting your paper please ensure you have read the Instructions for Authors and that your paper uses the prescribed style files. To submit your work, please use the submission page at the following Easychair address https://easychair.org/conferences/?conf=okbqa2017.

Accepted submissions will be included in the OKBQA2017 workshop proceedings (as abstracts), and will be presented during the workshop.
