  16. Under the Hood - Phrasing & Lemmatization

  17. Under the Hood: Phrasing/Anti-Phrasing • Phrasing: Known phrases are matched as a phrase • New York  “New York” • Based on common phrases, names, movie names, geographic names, etc. • Can detect multiple phrases within same query • Anti-Phrasing: Remove words irrelevant to the query • Who is… • What is… • Combines to create a better query • Who is George Bush  “George Bush” • What is the age of the earth  “the age of the earth” • How do I get to train station in New York  “get to” “train station” in “New York”

  18. Under the Hood:Lemmatization • Lemmatization improves recall • Literal matching only finds a fraction of candidates for a query • Ratio between base and full forms • English: 2 • German, French, Spanish: 5 – 10 • Russian, Polish: 40+ • Typical Cases: Singular/plural variation, case marking, etc. • Stemming vs. Lemmatization • Traditional stemming • Term is stemmed according to rules, e.g. walking  walk • Can easily result in “false” stemmings, e.g. Bobby Browning  Bobby Brown • Lemmatization • Rewriting of terms are controlled by language-sensitive dictionaries • Very comprehensive dictionaries; about 20 “man years”
