Brain microarray: finding needles in molecular haystacks.
Introduction When technical advances generated novel genetic markers in the 1980s, they were combined with linkage analysis allowing thousands of genes to be profiled simultaneously (Botstein et al., 1980; Weber and May, 1989). This capability has been used to isolate the molecular causes of most monogenetic disorders of the brain. With this success as a backdrop, the persistent difficulty in i...
متن کاملGuest Editors' Introduction: Information Discovery--Needles and Haystacks
For thousands of years, people have realized the importance of archiving and finding information. With the advent of computers, it became possible to store large amounts of information in electronic form — and finding useful needles in the resulting haystacks has since become one of the most important problems in information management. Many systems exist to help users navigate the considerable...
متن کاملFinding semantic needles in haystacks of Web text and links∗
Content and links are used to search, rank, cluster and classify Web pages. Here I analyze and visualize similarity relationships in massive Web datasets to identify how content and link analysis should be integrated for relevance approximation. Human-generated metadata from Web directories is used to estimate semantic similarity. Highly heterogeneous topical maps point to a critical dependence...
متن کاملNeedles and Haystacks: A Search Engine for Personal Information Collections
Information retrieval systems can be partitioned into two main classes: large-scale systems that make use of an inverted index or some other auxiliary data structure, intended for massive volumes of data; and the small-scale systems based upon sequential pattern matching that most computer users employ when hunting for missing email and news items. In this paper we describe a hybrid approach th...
متن کاملNeedles and Haystacks: Finding Funding for Medical Education Research.
Medical education research suffers from a significant and persistent lack of funding. Although adequate funding has been shown to improve the quality of research, there are a number of factors that continue to limit it. The competitive environment for medical education research funding makes it essential to understand strategies for improving the search for funding sources and the preparation o...
