Experiencing information, acquiring knowledge, and making decisions regarding web accessibility

Acquiring Comparative Commonsense Knowledge from the Web

Applications are increasingly expected to make smart decisions based on what humans consider basic commonsense. An often overlooked but essential form of commonsense involves comparisons, e.g. the fact that bears are typically more dangerous than dogs, that tables are heavier than chairs, or that ice is colder than water. In this paper, we first rely on open information extraction methods to ob...

Methods and Tools for Acquiring and Presenting Information and Knowledge in the Web

Aiming at a qualitatively new model of processing information in a heterogeneous environment such as the current and the future Web, it is desirable to focus among others on investigating new ways of working with information and knowledge in a heterogeneous environment, especially with imperfect and vague information from perhaps dubious sources. They should include acquiring information and kn...

Exploiting Domain Knowledge in Making Delegation Decisions

In multi-agent systems, agents often depend on others to act on their behalf. However, delegation decisions are complicated in normgoverned environments, where agents’ activities are regulated by policies. Especially when such policies are not public, learning these policies become critical to estimate the outcome of delegation decisions. In this paper, we propose the use of domain knowledge in...

Beyond information searching and browsing: acquiring knowledge from digital libraries

As one of the most complex and advanced forms of Internet information systems, digital libraries serve as an increasingly important channel to a vast array of information sources and services. However, from the standpoint of satisfying human’s information needs, the current digital library systems suffer from the following two shortcomings: (i) inadequate strategic level cognition support; (ii)...
