Crowdsourcing Question-Answer Meaning Representations
We introduce Question-Answer Meaning Representations (QAMRs), which represent
the predicate-argument structure of a sentence as a set of question-answer
pairs. We also develop a crowdsourcing scheme to show that QAMRs can be labeled
with very little training, and gather a dataset with over 5,000 sentences and
100,000 questions. A detailed qualitative analysis demonstrates that the
crowd-generated question-answer pairs cover the vast majority of
predicate-argument relationships in existing datasets (including PropBank,
NomBank, QA-SRL, and AMR) along with many previously under-resourced ones,
including implicit arguments and relations. The QAMR data and annotation code
is made publicly available to enable future work on how best to model these
complex phenomena.Comment: 8 pages, 6 figures, 2 table
Involving External Stakeholders in Project Courses
Problem: The involvement of external stakeholders in capstone projects and
project courses is desirable due to its potential positive effects on the
students. Capstone projects particularly profit from the inclusion of an
industrial partner to make the project relevant and help students acquire
professional skills. In addition, an increasing push towards education that is
aligned with industry and incorporates industrial partners can be observed.
However, the involvement of external stakeholders in teaching moments can
create friction and could, in the worst case, lead to frustration of all
involved parties. Contribution: We developed a model that allows analysing the
involvement of external stakeholders in university courses both in a
retrospective fashion, to gain insights from past course instances, and in a
constructive fashion, to plan the involvement of external stakeholders. Key
Concepts: The conceptual model and the accompanying guideline guide the
teachers in their analysis of stakeholder involvement. The model is comprised
of several activities (define, execute, and evaluate the collaboration). The
guideline provides questions that the teachers should answer for each of these
activities. In the constructive use, the model allows teachers to define an
action plan based on an analysis of potential stakeholders and the pedagogical
objectives. In the retrospective use, the model allows teachers to identify
issues that appeared during the project and their underlying causes. Drawing
from ideas of the reflective practitioner, the model contains an emphasis on
reflection and interpretation of the observations made by the teacher and other
groups involved in the courses. Key Lessons: Applying the model retrospectively
to a total of eight courses shows that it is possible to reveal hitherto
implicit risks and assumptions and to gain a better insight into the
interaction...Comment: Abstract shortened since arxiv.org limits length of abstracts. See

Neogeography: The Challenge of Channelling Large and Ill-Behaved Data Streams
Neogeography is the combination of user generated data and experiences with mapping technologies. In this article we present a research project to extract valuable structured information with a geographic component from unstructured user generated text in wikis, forums, or SMSes. The extracted information should be integrated together to form a collective knowledge about certain domain. This structured information can be used further to help users from the same domain who want to get information using simple question answering system. The project intends to help workers communities in developing countries to share their knowledge, providing a simple and cheap way to contribute and get benefit using the available communication technology
