The Best Answers? Think Twice: Online Detection of Commercial Campaigns in the CQA Forums
In an emerging trend, more and more Internet users search for information
from Community Question and Answer (CQA) websites, as interactive communication
in such websites provides users with a rare feeling of trust. More often than
not, end users look for instant help when they browse the CQA websites for the
best answers. Hence, it is imperative that they should be warned of any
potential commercial campaigns hidden behind the answers. However, existing
research focuses more on the quality of answers and does not meet the above
need. In this paper, we develop a system that automatically analyzes the hidden
patterns of commercial spam and raises alarms instantaneously to end users
whenever a potential commercial campaign is detected. Our detection method
integrates semantic analysis and posters' track records and utilizes the
special features of CQA websites largely different from those in other types of
forums such as microblogs or news reports. Our system is adaptive and
accommodates new evidence uncovered by the detection algorithms over time.
Validated with real-world trace data from a popular Chinese CQA website over a
period of three months, our system shows great potential towards adaptive
online detection of CQA spams.Comment: 9 pages, 10 figure
Quantum Particles as Conceptual Entities: A Possible Explanatory Framework for Quantum Theory
We put forward a possible new interpretation and explanatory framework for
quantum theory. The basic hypothesis underlying this new framework is that
quantum particles are conceptual entities. More concretely, we propose that
quantum particles interact with ordinary matter, nuclei, atoms, molecules,
macroscopic material entities, measuring apparatuses, ..., in a similar way to
how human concepts interact with memory structures, human minds or artificial
memories. We analyze the most characteristic aspects of quantum theory, i.e.
entanglement and non-locality, interference and superposition, identity and
individuality in the light of this new interpretation, and we put forward a
specific explanation and understanding of these aspects. The basic hypothesis
of our framework gives rise in a natural way to a Heisenberg uncertainty
principle which introduces an understanding of the general situation of 'the
one and the many' in quantum physics. A specific view on macro and micro
different from the common one follows from the basic hypothesis and leads to an
analysis of Schrodinger's Cat paradox and the measurement problem different
from the existing ones. We reflect about the influence of this new quantum
interpretation and explanatory framework on the global nature and evolutionary
aspects of the world and human worldviews, and point out potential explanations
for specific situations, such as the generation problem in particle physics,
the confinement of quarks and the existence of dark matter.Comment: 45 pages, 10 figure
