Abstract

Crowdsourced Labelling is a large scale data labelling process, solicits a large group of people to label the data, usually via Internet. This paper discusses about design and implementation of Web-based Crowdsourced Labelling. Supervised learning classification methods need labelled training data for its training phase. Unfortunately, in many cases, there aren’t any already available labelled training data. Large scale data labelling is a tedious and time consuming work. This research develops a web-based crowdsourced labelling which able to solicit a large group of people as data labeler to speed up the data labelling process. This system also allows multiple labeler for every data. The final label is calculated using Weighted Majority Voting method. We grabbed and used Facebook comments from the two candidates’ Facebook Page of 2014 Indonesian Presidential Election as testing data. Based on the testing conducted we can conclude that this system is able to handle all the labelling steps well and able to handle collision occurred when multiple labeler labelling a same data in the same time. The system successfully produces final label in CSV format, which can be processed further with many sentiment analysis tools or machine learning tools. Index Terms - Crowdsources labeling, web-based system, supervised learning, weighted majority voting.

Abstract

In this paper we will discuss how to design and analysis a repository system in university, Duta Wacana Christian University (DWCU). The system is web-based, and implements Dublin Core (DC) metadata, using tagging systems, and implements Open Archive Initiatives-Protocol for Metadata Harvesting (OAI-PMH) data provider. The term Institutional Repository (IR) appears since 2003 and is now widely used in various institutions including universities. IR university is a place that contains digital work data, both scientific and non-scientific research from entire academic community of the university. IR univesitry contains many formats such as documents (text), audio (sound), and video. Development of the system has been conducted by the author and team and produce a repository that has appropriate permissions to the stored data, it is applying the standard DC metadata and tagging on each of its file, it has preview feature, and able to perform searching based on tag and DC metadata that previously stored in it. The results concluded that implementation of DC metadata that store permanently in each file, causes each file has a unique metadata signature, so that each file downloaded from the system is actually (originally) comes from UKDW institutional repository. The use of tagging on each file allows categorization and retrieval based on tags, and OAIPMH protocol implementation allows IR data provider collaborate and integrate with other OAI-PMH systems, such as Portal Garuda that owned by Indonesian Higher Education (DIKTI). Index Terms - Institutional Repository (IR), metadata, Dublin Core (DC, tagging, OAI-PMH data provider.

Abstract

Implementation of Information Technology in agriculture sector is able to raise farming productivity. One of the Information Technology implementation is mapping system for agriculture land which has not only data collection but also strategic role. This paper discusses literature review of implementation of web mapping system, either from user perspective and functional perspective. On the end of the paper will discuss feature, opportunities, and challenges to develop and implement Web Mapping System. This paper also gives some recommendatios in order to support web mapping system implementation.
