2. Internet… • Home was BAMA, the Sprawl, the Boston-Atlanta Metropolitan Axis. Program a map to display frequency data exchange, every thousand megabytes a single pixel on a very large screen. Manhattan and Atlanta burn solid white. Then they start to pulse, the rate of traffic threatening to overload your simulation. Your map is about to go nova. Cool it down. Up your scale. Each pixel a million megabytes. At a hundred million megabytes per second, you begin to make out certain blocks in midtown Manhattan, outlines of hundred-year-old parks ringing the old core of Atlanta. • (William Gibson, Neuromancer, 1984, page 57). … or Google Earth?

3. Issues and Questions • The Internet as a Resource • InterNET • Characteristics of networks • Corpus Linguistics (CL) and Internet text • Patterns of interest to the language learner

4. Internet Map

5. UK Janet network 2001

6. another way of viewing it

7. Networks • Milgram’s experiments (1960s) • 160 letters sent out asking random people in Nebraska & Kansas to forward the letter to a person in Boston, but without the address. • Most of the letters got through. • In only about 6 steps.

8. Networks • Graph Theory • You want to link 50 towns with a road network, but don’t want to build 1,225 roads (50 * 49 ÷ 2). • Erdös proved in 1959 that 98 random roads (8%) will ensure the great majority get linked. • In general, for larger networks, you need only a tiny percentage of the possible links to get a network which works (traffic gets through). • For a network of 6 billion people, you need 0.000000004%, which is about 24 links (acquaintances). • Messages will get through from anyone .. to anyone.

9. Power Law • Nodes and connections obey a “power law”: “each time the number of links doubles, the number of nodes with that many links becomes less by about five times”. (Buchanan 2002: 83) • Are words in text anything like these networks?

10. Internet • a “scale-free” network • “The probability distribution of incoming links to HTML documents… follows a power law, generating a straight line on this logarithmic plot. The outgoing links have a similar distribution. This implies that the WWW is a scale-free network”. (Ball 2004:480)

11. Word Frequency lists • Zipf’s rank-frequency distribution of words (Zipf, 1965: 25) (A) “The James Joyce data; (B) the Eldridge data; (C) ideal curve with slope of negative unity.” (original caption)

12. Word Frequency lists — BNC • Zipf plot of word frequencies & ranks (Scott & Tribble in press) Based on whole BNC, nearly 400,000 types

13. Corpus Linguistics • Uncertain status as a discipline • Innovative in methodology • Focus on “the language” • relatively unfiltered data

14. as opposed to this? or this?

15. Internet text • Google • “Google examines more than 8 billion web pages to find the most relevant pages for any query and typically returns those results in less than half a second. No other search engine accesses more of the Internet or delivers more useful information than Google.” (http://www.google.co.uk/corporate/features.html)

16. But there are more sites • islands • sites not found by web-bots • sites not indexed by web-bots • … so not all the Internet can be seen

17. The problem: what verb goes with “battle”? • hold? • fight? • win? • take? • there + be? • struggle? • combat? • pitch?

18. Dictionaries • OED: “join, give, refuse, accept, offer, do battle” • Oxford Advanced Learner’s 1974: no verbs supplied • Cobuild 1988: examples show “fought” and “do battle”

19. LTP Dictionary of Selected Collocations • Verbs to the left: engage in, fight, force, go into, join in, lose, take part in, win ~ • Verbs to the right: ~ continues, dragged on, ended in stalemate, is in progress, raged • Adj: bitter, bloody, crucial, decisive, fierce, final, hopeless, important, last-ditch, long, long-running, major, mock, pitched, real, relentless, running, successful ~ • Phrases: fight a losing ~, outcome of ~

20. battle

21. fight battle

22. Webgetter • Settings: English only, minimum 100 words

23. Webgetter • In approx. 600,000 words, “battle” occurs nearly 4,000 times, about once every 150 words. • “An epic battle rages between the Forseti and the Muspell as the oceans rise and land disappears. The Forseti compel you to help protect their remaining land by taking charge of the ultimate war machine – the Battle Engine. Whether in walking or in flying mode, you have access to an array of destructive weapons and you receive constant direction from base command. By commanding a device so powerful and advanced, your battlefield decisions will shape the direction of each engagement and, ultimately, the entire war.”

24. Webgetter results • Collocated verbs in top 100 linked by MI score: • cheats(10 occurrences) “Battle engine Aquila cheats”(? is this a verb?) • gaming (9) • fought (43) is number 110 • Clusters: “battle was fought” (6)

25. BNC (written) • In 90 million words, “battle” comes over 6,000 times, once every 14,000 words. • Collocated verbs in top 100 linked by MI score: • fought(153)/fighting(93) • rages(5)/raged(12) • waged(10)/waging(12) • ensued(8)/ensuing(13) • defeated(39) • losing(68) • won(152) • commence(5)

26. BNC Written clusters • to do battle (54) • fighting a losing (24) • win the battle (22) • won the battle (22) • fighting a losing battle (21) • to fight a (15)

27. Conclusions (1) • The Internet is a powerful linked scale-free network with the capacity of linking nodes efficiently and fast, and is relatively robust • Connections within the Internet have characteristics of a power law • Word frequency lists share these characteristics … • … suggesting that grammar words are like Google. Yahoo, Microsoft web-sites, extremely often visited… • …but not in themselves informative • and other sites we visit are like lexical words… • …less visited but more informative

28. Conclusions (2) • The learner wants to know how words collocate • Collocation dictionaries – but not other dictionaries – give useful information • but no examples or not enough • Internet text is often strangely structured • after all the Internet is merely a noticeboard • New and often strange text-types or uses of familiar words

29. Conclusions (3) • The concordance + BNC gives a better view for the language learner, through • concordance lines • collocates • clusters
