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

THE ROLE OF JAVANESE CULTURE IN CHARACTER BUILDING AT ELEMENTARY SCHOOL

Nowadays, character education becomes a major concern in Indonesia. Character development has been done by various strategy, but the results is yet to be seen. Character development should beginin elementary school in order that the children's charactercould formed early so that it could be developed until they are mature. One of the efforts of character building is integrating the local wisdom in learning. One of them is the Javanese culture. Javanese culture has a variety of rules called the "unggah-ungguh" that always give good models to the public community, especially to the Javanese. Along with the times, the Javanese culture that upholds ethics began to degraded and replaced by foreign cultures that came later. The parents’ roles in instilling the Javanese culture to their children also decreased gradually. This paper will examine the Javanese culture’s roles toward the character building in elementary schools’ students. Descriptive method supported by a depth review of the literature and the previous studies is used in this paper as a method. Based on the results of these reviews, we obtain some information about the types and mechanisms of Javanese culture in character building of students, especially elementary school students
