講題：(1) Contents, Data and Tools: Why Openness Benefits Research
(2) The one and many maps: participatory and temporal diversities
in OpenStreetMap
摘要：
(1)
We shall review a few key notions in open content, open data, and open source.
We will use a few examples to illustrate why openness is good for (your) research.
In this presentation, we wish to emphasize the use of free software in making
research results more accessible and reusable.

OpenStreetMap is an open and collaborative project with thousands of people
contributing GPS traces and other data into the making of a global map of places
and networks. It is open in the sense that everyone can contribute to the project,
and results from the project are free for everyone to reuse. This is contrary to
traditional cartography where often a central authority controls the making of the
map and its release. Is OpenStreetMap more democratic, and in what sense?
Is OpenStreetMap more relevant to the mass, and how can we judge?
We define and use several metrics to measure temporal properties of defined
areas in OpenStreetMap, and to sample modes of participation in these areas.
These metrics are used to graph the datasets representing the current
OpenStreetMap so as to reveal unevenness in user participation and data temporality.
We use the dataset about Taiwan as a test case to observe participatory and
temporal diversities among different areas of Taiwan in OpenStreetMap.
