Little is known about what causes anti-social behavior online. The paper at hand analyzes vandalism and damage in Wikipedia with regard to the time it is conducted and the country it originates from. First, we identify vandalism and damaging edits via ex post facto evidence by mining Wikipedia’s revert graph. Second, we geolocate the cohort of edits from anonymous Wikipedia editors using their ...

This thesis aims to augment the Geographic Information Retrieval process with information extracted from world knowledge. This aim is approached from three directions: classifying world knowledge, disambiguating placenames and modelling users. Geographic information is becoming ubiquitous across the Internet, with a significant proportion of web documents and web searches containing geographic ...

While current GIS research has focused on technological issues of visualization and data organization, the emergence of new forms of collective authorship suggest we need new information frameworks and behaviors. How do individuals contribute place-based information to a digital commons? What are the authorship dynamics of such collective effort? For my research, I will use spatial data mining ...

In this paper, we describe the collection of a large structured dataset of temporally anchored relational data, obtained from the full revision history of the English Wikipedia. By mining (attribute, value) pairs from this revision history, we are able to collect a comprehensive, temporally-aware knowledge base that contains data on how attributes change over time. We discuss different characte...

At NTCIR-9, we participated in the cross-lingual link discovery (Crosslink) task. In this paper we describe our approaches to discovering Chinese, Japanese, and Korean (CJK) cross-lingual links for English documents in Wikipedia. Our experimental results show that a link mining approach that mines the existing link structure for anchor probabilities and relies on the “translation” using cross-l...

• Data mining: the techniques, methods and algorithms for finding patterns in structured data. • Data warehousing: the methods and techniques for managing data and processing complex analytical decision-support queries in databases. • Information Retrieval: the techniques, methods, algorithms and data models for finding information in unstructured (primarily, but not always, textual) data. • Co...

Pattern is a package for Python 2.4+ with functionality for web mining (Google + Twitter + Wikipedia, web spider, HTML DOM parser), natural language processing (tagger/chunker, n-gram search, sentiment analysis, WordNet), machine learning (vector space model, k-means clustering, Naive Bayes + k-NN + SVM classifiers) and network analysis (graph centrality and visualization). It is well documente...

We propose a method to mine novel, document-specific associations between terms in a collection of unstructured documents. We believe that documents are often best described by the relationships they establish. This is also evidenced by the popularity of conceptual maps, mind maps, and other similar methodologies to organize and summarize information. Our goal is to discover term relationships ...
