- 830 abstract "The combined efforts of human volunteers have recently extracted numerous facts from Wikipedia, storing them as machine-harvestable object-attribute-value triples in Wikipedia infoboxes. Machine-learning systems, such as Kylin, use these infoboxes as training data, accurately extracting even more semantic knowledge from natural language text. But in order to realize the full power of this information, it must be situated in a cleanly-structured ontology. This paper introduces KOG, an autonomous system for refining Wikipedia’s ontology towards this end. We cast the problem of ontology refinement as a machine learning problem and solve it using both SVMs and a more powerful joint-inference approach expressed in Markov Logic Networks. We present experiments demonstrating the superiority of the joint-inference approach and evaluating other aspects of our system. Using these techniques, we build a rich ontology, integrating Wikipedia’s infobox-class schemata with WordNet. We demonstrate how the resulting ontology may be used to enhance Wikipedia with improved query processing and other features.".

- 840 sameAs 840.
- 840 abstract "Yahoo Answers (YA) is a very diverse, and very large question-answer forum, acting not only as a medium for sharing technical knowledge, but as a place where one can seek advice, gather opinions, and satisfy one’s curiosity about a countless number of things. In this paper, we want to understand YA's knowledge sharing and activity. We analyze the forum categories and cluster them according to content characteristics and patterns of interaction among the users. While interactions in some categories resemble expertise sharing forums, others incorporate discussion, everyday advice and support. With such a diversity of categories in which one can participate, we find that some users focus narrowly on specific topics, while others participate across categories. This not only allows us to map related categories, but to characterize the entropy of the users’ interests. We find that lower entropy correlates with receiving higher answer ratings, but only for categories where factual expertise is primarily sought after. We combine both user attributes and answer characteristics to predict, within a given category, whether a particular answer will be chosen as the best answer by the asker.".

- 846 sameAs 846.
- 846 abstract "In this paper we study the characteristics of search queries submitted from mobile devices and report the query patterns derived from 20 million English queries by users in US, Canada, Europe, and Asia using various Yahoo! mobile oneSearch applications during a 2 months period in the second half of 2007. We examine the query distribution and the topical categories the queries belong to. We compare and contrast the search patterns between US and international queries, between search interfaces (XHTML vs. SMS), and between search options. We also have compared our results with previous studies wherever possible, and have confirmed some of the previous findings while finding interesting differences in the query distribution.".
