In web corpus construction, crawling is a necessary step, and it is probably the most costly of all, because it requires expensive bandwidth usage, and excess crawling increases storage requirements. Excess crawling results from the fact that the web contains a lot of redundant content (duplicates and near-duplicates), as well as other material not suitable or desirable for inclusion in web cor...

Wikipedia is a “free” online encyclopedia. It contains millions of entries in many languages and is growing at a fast pace. Due to its volume, search engines play an important role in giving access to the information in Wikipedia. The “free” availability of the collection makes it an attractive corpus for information retrieval experiments. In this paper we describe the evaluation of a search en...

Focused proof systems provide means for reducing and structuring the non-determinism involved in searching for sequent calculus proofs. We present a focused proof system for a first-order logic with inductive and co-inductive definitions in which the introduction rules are partitioned into an asynchronous phase and a synchronous phase. These focused proofs allow us to naturally see proof search...

Case 1. Kierra Malcom,† a 17 year old with homozygous sickle cell disease (HbSS), was on chronic erythrocytapheresis after she suffered a stroke at 8 years of age. With the intervention, her hemoglobin S level was consistently maintained between 25% and 35%. Iron chelation was commenced at the age of 10 years. She is currently on oral deferasirox and has a ferritin level of 1400 ng/mL. T2* live...

_ People query search engines to find answers to a variety of questions on the Internet. Search cost would have been greatly reduced if search engines could accept natural language questions as queries, and provide summaries that contain the answers to these questions. We introduce the notion of Answer-Focused Summarization, which is to combine summarization and question answering. We develop a...

The joining of high-intensity focused ultrasound with high-resolution MR guidance has created a system that can produce tissue destruction deep within solid organs without any invasion. Accurate targeting and thermal mapping are provided by MRI and allow very accurate deposition of energy in tissues that can be altered in response to near real-time thermal imaging produced by MR so that the var...

The space-time focusing of a (continuous) succession of localized X-shaped pulses is obtained by suitably integrating over their speed, i.e., over their axicon angle, thus generalizing a previous (discrete) approach. New superluminal wave pulses are first constructed and then tailored so that they become temporally focused at a chosen spatial point, where the wave field can reach very high inte...

The need for more and more specific reply to a web search query has prompted researchers to work on focused web crawling techniques for web spiders. Variety of lexical and link based approaches of focused web crawling are introduced in the paper highlighting important aspects of each. General Terms Focused Web Crawling, Algorithms, Crawling Techniques.
