ABOUTNESS: THE HUMAN FACTOR : ABOUTNESS: THE HUMAN FACTOR soasis&t Aboutness: Automatic Indexing & Categorization June 21, 2001 Inherent contradictions? : Inherent contradictions? Indexing, cataloging, classification depend on ability to discover and label topics in data A consistent, controlled, classification scheme facilitates Data analysis & visualization Intra-document linking by taxonomy nodes Investigative analysis of content (Shewhart June 21, 2001) The world cannot be organized into a single coherent vocabulary (Tobias 1996 ) Aboutness—The view from TREC-9 : Aboutness—The view from TREC-9 The notion of “aboutness” is considered as a set of terms evoking a subject concept, which is hopefully shared by many people including authors, indexers and the users of the system (Fujita 2000) In almost all computer applications, users must enter correct words for the desired objects or actions. For success without extensive training. . . the system must recognize terms that will be chosen spontaneously. We studied spontaneous word choice for objects . . . and found the variability to be surprisingly large. In every case two people favored the same term with probability <0.20. (Furnas et al. 1987) The Human Factor— Whose concept? : The Human Factor— Whose concept? A subject authority file (or a controlled vocabulary list or a thesaurus or list of approved topics or selected key words) is essential to an indexing project because is maintains consistency and accuracy. (Semonche 1993, p. 373) The Human Factor—The right label : The Human Factor—The right label HEMMER: So . . . the FBI mess right now. . . why you believe we were led to this point, to the FBI documents? HARRIS: Well, you know, most people. . . do word searches. And the same in Lexis legal research. You put a word in and you can find any document in which that word appears. Unfortunately, the FBI does not use that system in its document storage. They use indexes. So the index is only as good as the indexer. So if I index a certain document in certain ways, and for example, in the yellow pages, if you look under refrigerators, you won't find anything. You have to go to major appliances. And because the FBI uses this kind of an indexing system, I understand that it is very difficult to retrieve each and every document that might be relevant. (CNN May 31, 2001, Bill Hemmer interview with Jeffrey Harris, Former Federal Prosecutor) — Consistently applied : — Consistently applied At most 90 percent of the Census returns are correctly classified by the human editors, and the Dow Jones editors achieve only 83 percent recall and 88 percent precision when compared to an “expert” editor. . . . Human systems set the targets for acceptable levels of inconsistency and error for an automated system. (Fidel 1993, p. 285) :  Topics are inherently fuzzy Searchers are naive All documents retrieved should be relevant All relevant documents should be retrieved Indexing is about access Exercise : Exercise What are the articles about? Note language that is evidence of aboutness Is there more than one subject in the document? What is their relative importance to overall meaning? Assign index terms Select from list of subject terms Apply all relevant terms Rank terms in order of importance to the document Note prominent subjects that are NOT on the approved list Discussion : Discussion Major References Minor References, Subtopics Document types Survey Summary Review Bibliography : Bibliography Albrechtsen, Hanne.

They're not the Blackjacks, Royal Flushes or Silver Dollars, but the 51s, as in Area 51, the famously top-secret test site in the Nevada desert oft-rumored to be the mysterious location of captured UFO spacecraft and even alien beings.

Southern Arizona has become a popular crossing point for illegal immigrants since Border Patrol crackdowns in Texas and California prompted people to try to enter the United States through more isolated, inhospitable areas. Scores have died from exposure. It is believed that some of the undocumented immigrants were from the state of Veracruz.

Upon arrival on Earth, the material should be quarantined in a special laboratory similar to those used to study Ebola and other highly contagious, lethal diseases, the panel said, and unless it is completely devoid of any possible signs of life, it should be sterilized through heat or radiation before being released to researchers outside of the quarantine SPACE; MEDICINE AND HEALTH; ROCK AND STONE; MARS (PLANET); LIFE, EXTRATERRESTRIAL BACTERIA (90%); RESEARCH (90%); SPACE EXPLORATION (78%); TROPICAL DISEASES (76%) ORGANIZATION: AMERICAN GEOPHYSICAL UNION (59%); NATIONAL RESEARCH COUNCIL (59%) CHANG, KENNETH JOHN A WOOD (59%) Slide 17: St. Louis Post-Dispatch June 8, 2001 Friday "EVOLUTION" DESCENDS FROM A LONG LINE OF MOVIES; BUT IT IS THE CAST THAT MAKES THE LIGHTWEIGHT COMEDY WORK. Half the movies at the multiplex are really just an excuse for Hollywood to show off its toys. From computer-generated imagery to surgically enhanced bodies, summer movies are all about spectacle. Often, the difference between good and bad (that is, the difference between a "Shrek" and a "Pearl Harbor") is the quality of the script that the producers drape over the effects. But in the case of "Evolution," this effects-laden comedy succeeds because of the easygoing charm of its stars.
