The RuleML Doctoral Consortium is part of the RuleML International Symposium on Rules since 2011. It attracts Ph.D. researchers in the area of Rules and Markup Languages from different backgrounds (e.g. theoretical, application, vertical domain-specific) and encourages a constructive and fruitful interdisciplinary approach. At the doctoral symposium, students present their ideas in a dynamic and friendly setting as well as interact with academics and commercial experts in the field, who evaluate their research projects from both theoretical and application points of view.

The Human Language Technology Track addresses the knowledge acquisition bottleneck that arises when converting the vast amount of regulatory text on the Web expressed in natural language to formal, machine-processable rules. Six papers in total were accepted to the Track, three of which appear in the associated LNCS volume and three of which appear in this volume. Topics represented in the Track include using controlled languages, extracting semantic information from legislative text, and mapping English onto fuzzy logic. There are six talks and one tutorial.

We warmly thank all authors, students, supervisors, referees, co-chairs, members of the program committee and the organizing team that made the RuleML2013 Symposium, International Web Rule Challenge, and Doctoral Consortium a great success.
