Introduction
This book brings together for the first time the collected wisdom of international leaders in the theory and practice in the emerging field of cultural heritage crowdsourcing. It features eight accessible case studies of groundbreaking projects from leading cultural heritage and academic institutions, and four thought-‐provoking essays that reflect on the wider implications of this engagement for participants and on the institutions themselves
Understanding Task Design Trade-offs in Crowdsourced Paraphrase Collection
Linguistically diverse datasets are critical for training and evaluating
robust machine learning systems, but data collection is a costly process that
often requires experts. Crowdsourcing the process of paraphrase generation is
an effective means of expanding natural language datasets, but there has been
limited analysis of the trade-offs that arise when designing tasks. In this
paper, we present the first systematic study of the key factors in
crowdsourcing paraphrase collection. We consider variations in instructions,
incentives, data domains, and workflows. We manually analyzed paraphrases for
correctness, grammaticality, and linguistic diversity. Our observations provide
new insight into the trade-offs between accuracy and diversity in crowd
responses that arise as a result of task design, providing guidance for future
paraphrase generation procedures.Comment: Published at ACL 201
Crowd Research at School: Crossing Flows
It has become widely known that when two flows of pedestrians cross stripes
emerge spontaneously by which the pedestrians of the two walking directions
manage to pass each other in an orderly manner. In this work, we report about
the results of an experiment on crossing flows which has been carried out at a
German school. These results include that previously reported high flow volumes
on the crossing area can be confirmed. The empirical results are furthermore
compared to the results of a simulation model which succesfully could be
calibrated to catch the specific properties of the population of participants.Comment: contribution to proceedings of Traffic and Granular Flow 2013 held in
