The field of Culturomics exploits “big data” to explore human society at population scale. Culturomics increasingly needs to consider geographic contexts and, thus, this research develops a geospatial visual analytical approach that transforms vast amounts of textual data into emotional heatmaps with fine-grained spatial resolution. Fulltext geocoding and sentiment mining extract locations and latent...
According to some researchers, the wave of crowds we are witnessing in recent years is another example of the challenges for the CSCW community, a line of research that fights against the dilemma of fragmentation. The reflexes of this phenomena in projects of different branches have caused a change of paradigm in how products and services are idealized and how the projects are conducted in a collaborative...
This paper contains analysis and simulation of recent dynamic models, describing human emotion. The pharmacological discussions lead to a new model of drug taking, which also have a better performance for description of psychological and psychiatric phenomena. Studying the effects of the order of fractional model, obtains an advantage of the fractional order model over the integer order one.
Human flesh search or human-powered search is created by Chinese internet users. It means one question is issued by network platform, the answer is not given by algorithm of machine search engine but by internet users. It often searches some information that net does not contain, and has been a popular phenomenon of the net. So, it is very meaningful to research on its information transfer mechanism.
Vandalism is a main problem of the Wikipedia and other content management systems that have open-edit policy. Due to its popularity, Wikipedia has been attacked very regularly. To detect and clean up these bad contents, it requires a lot of human time to inspect the changes between revisions which should not be much wasted for such task. There have been many attempts to alleviate vandalisms. Some...
A network of concepts is built from Wikipedia documents using a random walk approach to compute distances between documents. Three algorithms for distance computation are considered: hitting/commute time, personalized page rank, and truncated visiting probability. In parallel, four types of weighted links in the document network are considered: actual hyperlinks, lexical similarity, common category...
In order to talk to each other meaningfully, conversational partners utilize different types of conversational knowledge. Due to the fact that speakers often use grammatically incomplete and incorrect sentences in spontaneous language, knowledge about conversational and terminological context turns out to be as much important in language understanding as traditional linguistic analysis. In the context...
Though largely spontaneous and loosely regulated, the process of peer production within online communities is also supplemented by additional coordination mechanisms. In this respect, we study an emergent organizational practice of the Wikipedia community, the use of template messages, which seems to act as effective and parsimonious coordination device to signal quality concerns or other issues that...
The 3 dimensional anatomical data visualization is necessary for better understanding and describing of functionality of anatomical parts in education process and medical treatment. This paper proposes a platform that provides 3 dimensional visualization of the VKH (Visible Korean Human) data. The VKH is an extensive real image database made on the base of photographs of sliced in 0.2 mm intervals...
In recent years, the explicit semantic analysis (ESA) method has got a good performance in computing semantic relatedness (SR). However, ESA method has failed to consider the given context of the word-pair, and generates the same semantic concepts for one word in different word-pairs. It canpsilat exactly determine the intended sense of an ambiguous word. In this paper, we propose an improved method...
Ontologies are becoming more and more popular as background knowledge for intelligent applications. Up to now, there has been a schism between manually assembled, highly axiomatic ontologies and large, automatically constructed knowledge bases. This paper discusses how the two worlds can be brought together by combining the high-level axiomatizations from the standard upper merged ontology (SUMO)...
Wikipedia is nowadays one of the most valuable information resources; nevertheless, its current structure, which has no formal organization, does not allow to always have a useful browsing among topics. Moreover, even though most Wikipedia pages include a "See Also" section for navigating through those articles' related Wikipedia pages, the only references included here are those which authors...
