- 823 sameAs 823.
- 823 abstract "Local aspects of Web search --- associating Web content and queries with geography --- is a topic of growing interest. However, the underlying question of how spatial variation is manifested in search queries is still not well understood. Here we develop a probabilistic framework for quantifying such spatial variation; on complete Yahoo! query logs, we find that our model is able to localize large classes of queries to within a few miles of their natural centers based only on the distribution of activity for the query. Our model provides not only an estimate of a query's geographic center, but also a measure of its spatial dispersion, indicating whether it has highly local interest or broader regional or national appeal. We also show how variations on our model can track geographically shifting topics over time, annotate a map with each location's ``distinctive queries,'' and delineate the ``spheres of influence'' for competing queries in the same general domain.".

- 826 sameAs 826.
- 826 abstract "This paper presents an extensive study about the evolution of textual content on the Web. That is, how some new pages are created from scratch while others are created using already existing content. We show that a significant fraction of the Web is a byproduct of the later case. We present an estimation of how our finds can be applied to other Web data sets. We introduce the concept of Web genealogical tree, in which every page in a Web snapshot is classified into a component. We study in detail these components, characterizing the copies and identifying the relation between a source of content and a search engine, by comparing page relevance measures, documents returned by real queries performed in the past, and click-through data. We observe that sources of copies are more frequently returned by queries and more clicked than documents in general.".

- 828 sameAs 828.
- 828 abstract "Typical web sessions can be hijacked easily by a network eavesdropper in attacks that have come to be designated ``sidejacking.'' The rise of ubiquitous wireless networks, often unprotected at the transport layer, has significantly aggravated this problem. While SSL can protect against eavesdropping, its usability disadvantages often make it unsuitable when the data is not considered highly confidential. Most web-based email services, for example, use SSL only on their login page and are thus vulnerable to sidejacking. We propose SessionLock, a simple approach to securing web sessions against eavesdropping without extending the use of SSL. SessionLock is easily implemented by web developers using only JavaScript and simple server-side logic. Its performance impact is negligible, and all major web browsers are supported. Interestingly, it is particularly easy to implement on single-page AJAX web applications, e.g. Gmail or Yahoo mail: they could deploy it with only 200 lines of JavaScript and 50 lines of server-side verification code.".
