A corpus search methodology for focus realization
Poster presentation, 157th Meeting of the Acoustical Society of America. Abstract appears in J. Acoust. Soc. Am. Volume 125, Issue 4, pp. 2573-2573.We describe a methodology for investigating the semantic-grammatical
conditioning and phonetic realization of contrastive intonation using a web
harvest of particular word strings followed by grammatical and acoustic
analysis. A commercial audio web search engine using speech recognition
retrieved 179 MP3 files purportedly containing a token of the string 'than I
did.' In this comparative clause fragment, contrastive focus commonly falls
on the subject 'she did more than I_F did' , on 'did', 'I wish I had done more
than I did_F', or following 'I said more now than I did before_F' . The 96 true
tokens of 'than I did' were classified into the categories 'subject', 'did',
and 'following' by grammatical and semantic criteria. For each token, 5
segment intervals were hand-annotated and more than 300 acoustic parameters
extracted using a Praat script. SVM machine learning classifiers were
trained that identify focus classes by acoustic criteria. On a 10-fold crossvalidation
test, the classifier achieves 90.2% accuracy in discriminating the
dominant 'subject' and 'following' classes. In a listening task, human subjects
achieved comparable accuracy of 90.3 given only the acoustic target
'than I did'. Stepwise logistic regression revealed measures of duration, f0,
intensity, formants, and formant bandwidths among the significant factors
Realization of Semantic Atom Blog
Web blog is used as a collaborative platform to publish and share
information. The information accumulated in the blog intrinsically contains the
knowledge. The knowledge shared by the community of people has intangible value
proposition. The blog is viewed as a multimedia information resource available
on the Internet. In a blog, information in the form of text, image, audio and
video builds up exponentially. The multimedia information contained in an Atom
blog does not have the capability, which is required by the software processes
so that Atom blog content can be accessed, processed and reused over the
Internet. This shortcoming is addressed by exploring OWL knowledge modeling,
semantic annotation and semantic categorization techniques in an Atom blog
sphere. By adopting these techniques, futuristic Atom blogs can be created and
deployed over the Internet
Challenges and potential of the Semantic Web for tourism
The paper explores tourism challenges and potential of the Semantic Web from a theoretical and industry perspective. It first examines tourism business networks and explores a main theme of network interoperability - data standards- followed by technology deficiencies of Web 1.0 and 2.0 and Semantic Web solutions. It then explicates Semantic opportunities and challenges for tourism, including an industry perspective through a qualitative approach. Industry leaders considered that the new Web era was imminent and heralded benefits for supply and demand side interoperability, although management and technical challenges could impede progress and delay realisation
A Semantic Web of Know-How: Linked Data for Community-Centric Tasks
This paper proposes a novel framework for representing community know-how on
the Semantic Web. Procedural knowledge generated by web communities typically
takes the form of natural language instructions or videos and is largely
unstructured. The absence of semantic structure impedes the deployment of many
useful applications, in particular the ability to discover and integrate
know-how automatically. We discuss the characteristics of community know-how
and argue that existing knowledge representation frameworks fail to represent
it adequately. We present a novel framework for representing the semantic
structure of community know-how and demonstrate the feasibility of our approach
by providing a concrete implementation which includes a method for
automatically acquiring procedural knowledge for real-world tasks.Comment: 6th International Workshop on Web Intelligence & Communities (WIC14),
