The OKE challenge invites researchers and practitioners from academia as well as industry to compete to the aim of pushing further the state of the art in knowledge extraction from text for the Semantic Web. The challenge has the ambition to provide a reference framework for research in this field by redefining a number of tasks typically from information and knowledge extraction by taking into account Semantic Web requirements and has the goal to test the performance of knowledge extraction systems.

This year, the challenge goes in the fourth round and consists of four tasks which include named entity identification, disambiguation by linking to a knowledge base as well as relation and knowledge extraction. The challenge makes use of small gold standard datasets that consist of manually curated documents and large silver standard datasets that consist of automatically generated synthetic documents. The performance measure of a participating system is twofold based on (1) Precision, Recall, F1-measure and on (2) Precision, Recall, F1-measure with respect to the runtime of the system.

This year, the challenge comprises the following tasks:
Task 1: Focused Named Entity Identification and Linking
Task 2: Broader Named Entity Identification and Linking
Task 3: Relation Extraction
Task 4: Knowledge Extraction

Participants will be expected to describe their solution and results on the training datasets over a 5 page paper. In particular, a short summary of the approach chosen, a link to the experimental results and an analysis of the strengths and weaknesses of the approach are expected.
