Summary

Much of information retrieval is by exhaustive search and reading documents. String matches may include wild cards. Can limit the scope of search; e.g., titles and abstracts may improve relevance. Phrase search is helpful. (cbb 10/07)
Subtopic: search strategy up

Quote: provide users with a paradigm for an effective search strategy [»kerrST_1986]

Subtopic: result categories up

Quote: automatic categorization of search results by a small model of queries and a large, domain-specific terminology model; DynaCat for medicine [»pratW7_1999]
Quote: compared automatic categorization to clustering and ranking; more answers, liked better, ranked best [»pratW7_1999]

Subtopic: neighborhood search up

Quote: WebGlimpse allows neighborhood search computed at indexing time; allows jumps to related, close-by pages [»manbU1_1997]
Quote: query-initiated browsing -- locally navigate within a neighborhood; allows for localized similarity [»furnGW3_1997]

Subtopic: autonomous searching up

Quote: agents are semi-intelligent programs that carry out your goals; e.g., personal news reporters that scour the networks for relevant items [»lindO_1992]

Subtopic: text search vs manual indexing up

Quote: study found searching on titles and abstracts as good as controlled keywords [»saltG7_1986]
Quote: literature indicates that text searching is as good or better than manual indexing [»saltG7_1986]
Quote: full-text search is the model for computerized search and retrieval; an automatically produced index is solely for efficiency [»swanDR10_1960]

Subtopic: phrase searching up

Quote: to correlate 3-4 terms need to treat item pairs as phrases; text is naturally correlated [»silvC9_1999]
Quote: use nextword index for phrase queries; 3x faster at 3% extra space [»bahlD8_2002]
Quote: phrases are not substantially superior to single terms for indexing; nor are sophisticated analysis tools [»saltG4_1970]
Quote: efficient phrase queries using nextword and phrase indexes with inverted files; 4x faster, 25% more space [»willHE10_2004]

Subtopic: failure to see information up

Quote: learners often failed to find information even when it was in front of them [»carrJM_1990]

Subtopic: desktop metaphor for browsing up

Quote: the Mac-style user interface is a browsing interface that works well for 100-500 resources [»lindO_1992]

Subtopic: simple icons up

Quote: with blank icons, users search filenames instead of first searching icon types [»byrnMD10_1991]
Quote: simple icons help users to search documents with a GUI, while complex icons are no better than simple rectangles [»byrnMD4_1993]

Subtopic: similarity by facial features -- mugshoots up

Quote: use facial features to present likely mugshoots; quicker identification better, 90% found in first 8 mugshoots [»leeE4_1993]
Quote: identified mugshoot features by distinguishing all pairs of photos, and selected 90 features with good properties; e.g., thin vs. thick neck [»leeE4_1993]

Subtopic: search using filters -- multiple views up

Quote: can define multiple views of a record file; specify a filter, a sort order, and a formatting document [»smitDC4_1982]
Quote: match mail messages against a form [»kentJ8_1988]
Quote: nine pattern-matching filters such as exact, prefix and wildcard [»kentJ8_1988]
