Kurzfassung
Without the proliferation of formal semantic annotations, the
Semantic Web is certainly doomed to failure. In earlier work we
presented a new paradigm to avoid this: the 'Self Annotating Web',
in which globally available knowledge is used to annotate
resources such as web pages. In particular, we presented a
concrete method instantiating this paradigm, called PANKOW
(Pattern-based ANnotation through Knowledge On the Web). In
PANKOW, a named entity to be annotated is put into several
linguistic patterns that convey competing semantic meanings. The
patterns that are matched most often on the Web indicate the
meaning of the named entity --- leading to automatic or
semi-automatic annotation.
In this paper we present C-PANKOW (Context-driven PANKOW),
which alleviates several shortcomings of PANKOW. First, by downloading
abstracts and processing them off-line, we avoid the generation of large
number of linguistic patterns and correspondingly large
number of Google queries.
Second, by linguistically analyzing and normalizing the downloaded
abstracts, we increase the coverage of our pattern matching
mechanism and overcome several limitations of the earlier pattern
generation process. Third, we use the annotation context in order
to distinguish the significance of a pattern match for the given
annotation task. Our experiments show that C-PANKOW
inherits all the advantages of PANKOW (no training required etc.),
but in addition it is far more efficient and effective.
