Quote: web search concerns authoritativeness instead of relevance; trusted source of correct information that has a strong web presence [»boroA2_2005]

Quote: hyperlinks are endorsements for web pages; a network of recommendations that identifies authoritative documents [»boroA2_2005]

Quote: want authoritative results from broad-topic queries; the set of relevant results is too large [»kleiJM9_1999]

Quote: even though the World Wide Web was built on the idea of links, global navigation has been replaced by search engines [»furnGW3_1997]

Quote: Google records proximity, font size, and raw HTML for all pages [»brinS4_1998]

Quote: a search for "Bill Clinton" should return reasonable results

Quote: in a hypertext, explore the original context for items; e.g., articles, books, or other hypertext units

Quote: with hypertext, continually uncover new items of interest, often with growing relevance

Quote: three times more clicks for the top search result than the second position; by swapping results [»joacT8_2007]

Quote: strong presentation bias for search results even if you present the top 10 results in reverse order [»joacT8_2007]

Quote: skipped search results are clearly less relevant than selected results; pairwise relative preference had 80% agreement with manually ranked results [»joacT8_2007]

Quote: the best link analysis algorithm ranks nodes by their reachability; BFS combines InDegree with the Hits algorithm; 44% highly relevant [»boroA2_2005]

Quote: identify communities as bipartite graph of three web pages that all point to the same three other web pages; 95% had a unifying topic [»chakS8_1998]

Quote: tightly-knit communities, cycles, and isolated components are generally irrelevant; reachability and high in-degree are better measures of relevance; BFS/InDegree better than Hits/PageRank [»boroA2_2005]

Quote: link analysis algorithms find the Web context of a query; locate highly relevant pages that do not contain the actual query words [»boroA2_2005]

Quote: online metadata consists of links (anchor text), tags of pictures or URLs, page views (access logs), and free-form reviews or comments [»ramaR8_2007]

Quote: WebGlimpse allows neighborhood search computed at indexing time; allows jumps to related, close-by pages [»manbU1_1997]

Quote: ScentTrails faster than ShortScent; both faster than searching or browsing; company site with 3-4 links from home page to destination [»olstC9_2003]

Quote: ScentTrails allowed simultaneous use of browsing cues and search cues; e.g., find a copier with recyclable toner [»olstC9_2003]

Quote: study of user searches at www.excite.com [»jansBJ1_1998]

Quote: 6% of Excite users used AND or "..."; 1% used parentheses [»jansBJ1_1998]

Quote: two-thirds of Excite users used only one query; a fifth modified it once [»jansBJ1_1998]

Quote: more than half of Excite users only viewed first results page; a fifth viewed two pages of ten results per page [»jansBJ1_1998]

Quote: a quarter of the 63 top subject terms were sexual; 10% of the 63 top subject terms were places (e.g., state, american); 8% were economic (e.g., employment, jobs) [»jansBJ1_1998]

Quote: 16% of the 63 top subject terms were modifiers (e.g., free, new, big)

Quote: average query on Excite contained 2.3 terms; a third were one term only; much shorter than normal IR queries [»jansBJ1_1998]

Quote: analysis of AltaVista search query log; 25 most common queries covered 1.5% of total; most sessions consisted of one query, viewed one screen of results [»silvC9_1999]

Quote: clicks on search results can provide implicit feedback to the search engine [»joacT8_2007]

Quote: click streams and attentional metadata outweighs all other metadata; about 46 billion clicks per day worldwide [»ramaR8_2007]

Quote: 5% of Excite queries used 'More Like This'; traditional IR searching uses relevance feedback more [»jansBJ1_1998]

Quote: iterative search by identifying relevant and irrelevant documents; augment query with keywords from relevant documents [»saltG4_1970]

Quote: compare search engines by interleaving results from each engine [»joacT8_2007]

Quote: PageRank poor for common queries, good for sparse queries such as 'jaguar'; mixes different communities; promotes different pages than other search algorithms [»boroA2_2005]

Quote: peer-review is an artifact of journal publishing; will be replaced by autonomous references from respected sources [»pempS7_2000]

Quote: Clever analyzes hyperlinks to identify authorities on a topic and hubs with links to authorities [»chakS8_1998]

Quote: definition of PageRank algorithm; iterative calculation using citations, out links, and damping factor [»brinS4_1998]

Quote: rank web pages by counting backlinks to page; normalize by number of links; PageRank is probability of a visit [»brinS4_1998]

Quote: high PageRank if many pages point to the page, or if highly ranked pages point to the page [»brinS4_1998]

Quote: improved algorithm for PageRank; sum of values is one; handles isolated cycles and dangling pages [»kimSJ3_2002]

Quote: the iterative algorithm for hubs and authorities converges to the principal eigenvectors of the weighting matrices [»kleiJM9_1999]

Quote: index anchor text as well as target; 259 million anchors for 24 million pages [»brinS4_1998]

Quote: index the anchor text as a title of the target page; helps identify a document; good for Web searching [»zobeJ7_2006]

Quote: running the web crawler generated a fair amount of e-mail and phone calls; need to solve problems as they occur [»brinS4_1998]

Quote: search is parallelizable by randomly dividing index into pieces called index shards; a pool of machines for each shard [»barrLA3_2003]

Quote: problem of manipulating search engines for profit; e.g., metadata is easily abused since it is invisible [»brinS4_1998]
