Imagine a system that can push highly selective information right to our hands when and only when we need it. This requires a mind-reading machine, but unfortunately we don't have one --- yet. User profiling attempts to estimate what is most important ...

Question-Answering (QA) service is a growing area of research study, and commercial QA systems have recently been developed. We are motivated to provide complementary QA service that answers questions in advertisements (ads). These days with almost all ...

In this paper, we experimentally study how web searchers select the keywords to describe their information needs and specifically we investigate whether query keyword selections are influenced by the results the users reviewed for a previous search. For ...

As the volume of multimedia data available on internet is tremendously increasing, the content-based similarity search becomes a popular approach to multimedia retrieval. The most popular retrieval concept is the k nearest neighbor (kNN) search. For a ...

For an XPath expression q and a DTD D, q is satisfiable under D if there exists an XML document t such that t is valid against D and that the answer of q on t is nonempty. Evaluating an unsatisfiable XPath expression is meaningless, since such an ...

Generalization of web sessions is an effective approach used to overcome two major challenges in web usage mining, namely quality and scalability. Given a concept hierarchy, such as a website, generalization replaces actual page-clicks with their ...

Seed sets are of significant importance for trust propagation based anti-spamming algorithms, e.g., TrustRank. Conventional approaches require manual evaluation to construct a seed set, which restricts the seed set to be small in size, since it would ...

Contextual advertising seeks to place relevant ads to generic web pages based on their contents. Recently, it has been observed that classifying web pages into a well-organized taxonomy of topics is promising for matching topically relevant ads to web ...

In this paper, we present how to use graph model for clustering Vietnamese document incrementally. Graph based model allows us to model completely the structure of not only each document but also the whole collection of documents. The graph structure is ...

Many bursty topics which are difficult to summarize and search exist in web forums. Most existing topic detection and tracking (TDT) methods deal with the news stories, but the language used in web forums are much casual, oral and informal compared with ...

A large number of wrappers generate tables without column names for human consumption because the meaning of the columns are apparent from the context and easy for humans to understand, but in emerging applications, labels are needed for autonomous ...

The first task any individual faces after joining an online social network (OSN) is locating friends that are present on that particular site. Most OSNs offer some variation of a tool that imports email contact lists to facilitate the task of finding ...

Ambiguous personal names are common on the Web, which pose a challenge for many different tasks. The traditional disambiguation employs the clustering methods. However, without reference entity tables, the clustering method can only identify whether two ...

We propose a method for finding an intermediate entity between two examples on the Web. For example, a user wants to find events that occurred between the Battle of Red Cliffs and the death of Cao Cao. In this situation, the user wants to find something ...

In this paper we introduce a novel approach for the thematic organization of bibliographic records that builds upon a semantic relatedness measure we have implemented for this task. In particular, we introduce the Omiotis measure, which captures the ...
