2 An advantage of investigating language through corpora is that languages are always in flux. Corpora are not only language in use but science in progress or technology in progress, and what we find in corpora will be in dictionaries after five years or so.

3 A corpus is a computerized collection of texts. The texts may be in spoken, written or intermediate forms. The spoken texts are the transcription of speeches, like, for example, the transcription of BBB (Bush, Blair and Berlusconi’s speeches). BBB is, in fact, a spoken corpus. An example of written corpus is EIFECO, whose English texts come from the English weekly magazine The Economist, and whose Italian texts come from IlSole24Ore. What is a corpus?

10 Alcuni anni fa, le principali banche internazionali hanno capito la scarsa redditività dei prestiti. Così, hanno cominciato a disfarsi dei propri mutui, riconfezionandoli e rivendendoli sotto forma di titoli, oppure ottenendo che il rischio collegato ai prestiti venisse preso in carico da altri. Questa politica ha dato buoni frutti. I numerosi fallimenti societari avvenuti nel 2001 e 2002 – compresi quelli di Enron e WorldCom, i maggiori di tutti i tempi in USA – infatti non hanno avuto l’effetto devastante sui bilanci delle grandi banche che molti prevedevano. I due principali istituti americani ne hanno risentito appena. Nel secondo trimestre di quest’anno, Citigroup ha realizzato 4,3 miliardi di dollari di utili (+12% rispetto all’anno precedente)… The Economist The world’ leading banks decided some years ago that lending is a mug’s game. They began to get rid of their loans, repacking them and selling them off as securities, or getting others to re-insure their risk. And the policy has been bearing fruit. The glut of corporate bankruptcies in 2001 and 2002 – including the two biggest of all time, Enron and World Com – have not had the devastating effect on the big banks’ balance sheets that might have been expected. The two biggest banks in America, for instance, have hardly registered a tremor. Citi- group’s profits for the second quarter of this year were $4.3 billion (12% up on a year earlier), and those of J.P. Morgan Chase were $1.8 billion for the same …

11 E in occasione di un discorso tenuto lo scorso maggio, Alan Greenspan, presidente della Federal reserve, ha dichiarato che, grazie alla ripartizione dei rischi delle banche, il settore finanziario è diventato più forte e le singole istituzioni che lo compongono ora sono meno vulnerabili agli shock. Quel che è sicuro è che il sistema finanziario internazionale è più solido se le banche si assumono un minore rischio sul credito. La cattiva gestione dei prestiti in passato, infatti, ha provocato numerosi problemi nel settore e gli istituti, che rivestono un ruolo unico nel sistema di pagamento e nella distribuzione della liquidità, sono esposti alle crisi in misura nettamente superiore alle altre …. The Economist Alan Greenspan, chairman of America’s Federal Reserve, said in a speech in May that this spreading of the banks’ risks has made the financial sector more resilient, and individual institutions within it less vulnerable to shocks. It can indeed be argued that the world’s financial system is safer if banks carry less of the overall credit risk. Their previous mismanagement of credit has caused so many damaging banking crises in the past; and banks, with their unique role in the payment system and the distribution of liquidity, are prone to systemic risk in a way that is not true of other financial institutions. Better, in that case, that they are strong, and that risks and losses are borne by a wider investment pool.

17 The Economist La foresta da un pezzo non è più pietrificata, anzi dà prova di sapersi adeguare alle dinamiche europee, ma le scorie di decenni di inefficienza restano nel Dna del sistema creditizio italiano. É quanto emerge dalla prima indagine della R&S di Mediobanca sul sistema bancario europeo, un'analisi sui 37 principali gruppi creditizi continentali, esaminati nell'arco di tempo di sette anni dal 1995 al 2001: una task force con oltre miliardi di euro di attivo, pari al 60% del totale continentale. La più grande è la Deutsche Bank con 918 miliardi mentre è il San Paolo Imi a chiudere la lista dei 37 big con 170 miliardi di attivo. Perché proprio 37? Mediobanca ha selezionato le maggiori in modo che la più piccola rappresenti … EVERY now and again, the 18 men and women who set interest rates for the euro area hold their monthly meeting not at the European Central Bank (ECB) in Frankfurt, but somewhere else in the single- currency zone. This week was just such an occasion, with Berlin playing host on May 4th. Not that it made any difference: rates were held at 2% for the 23 rd month in a row. In that time, the ECB has watched America's Federal Reserve raise interest rates eight times—most recently by a quarter of a percentage point, to 3%, on May 3rd. Politicians in the ECB's host country might have hoped that a trip across Germany would prompt the central bankers to spot what they seem to have missed on their …

19 Interview on the European Constitution June 1 st, 2005 Question: Do you accept this as the end of the treaty? Tony Blair: I think what is important now is to have a time for reflection. We have the Dutch referendum in a couple of days time the Europe council in the middle of June where leaders can discuss the implications of the votes that have taken place but I think that underneath all this there is one profound question which is about the future of Europe and in particular the future of the European economy and how it deals with the modern pressures of globalization and technological change and how we insure the European economy is strong and prosperous in the face of those chanllenges. Underlying about all these debates about the constitution is that central economic challenge. Question: But is that not the problem the French have rejected the more liberal economic model which we in Britain are pushing for. What changes can be made to the treaty to make it acceptable to both the French and the British. Tony Blair: This is, I think, why we have to have this bigger debate in Europe. The constitution is a perfectly sensible set of rules to govern a Europe that is no longer 15 countries but 25 and perhaps 30 or more but the question that is being debated...

20 Blair’s audio Mr President, Colleagues. It is a very great pleasure to be with you here this afternoon in the European Parliament in Strasbourg, and let me add my word of welcome to our colleagues from Ukraine. If at any point in time we should ever feel lacking in confidence about Europe and its values, then the interest of people such as our Ukrainian friends should tell us that the values of Europe are strong and are much envied by so much of the rest of the world. Mr President, my purpose in coming here today is, as I explained I would, to report back on what we intend over these coming weeks to be the basis of the UK Presidency, and I have with me Douglas Alexander, who is our Europe Minister, and after I have left he will stay to answer more questions - especially the difficult questions. However I shall be here, I am pleased to say, for at least an hour and a half to hear both your comments and to answer some of those questions myself. Can I also say, just at the very outset, to explain how we want to take forward the Presidency over these coming weeks. On 23 June in Brussels we set out an essential vision as to how we combat the challenge of globalisation, and I think it is agreed generally in Europe that we need to get Europe moving and we need to get it moving in the right direction. The question is how we do that? We now have an opportunity, both in the informal summit, which is tomorrow, and then in the formal summit in December, to set out that direction and put in place the specific policies to match it. So over these two summits our idea is first to agree the right direction for Europe economically; then secondly to set out some new priority areas for European action; and then thirdly, on the basis of that and in the context of that, to get a budget deal in December at the formal Council.

21 The beginning of Corpus Linguistics can be located around the late 1950s and the early 1960s. The Brown Corpus British National Corpus (BNC) Bank of English (BoE) The LOB Corpus MICASE American National Corpus (ANC)

22 The Brown Corpus of Standard American English was the first of the modern, computer readable, general corpora. It was compiled by W.N. Francis and H. Kucera, Brown University, Providence, RI. The corpus consists of one million words of American English texts printed in The Brown corpus consists of 500 texts, each consisting of just over 2,000 words. The texts were sampled from 15 different text categories. The number of texts in each category varies.

23 The LOB corpus (Lancaster-Oslo/Bergen Corpus) was compiled by researchers in Lancaster, Oslo and Bergen. It consists of one million words of British English texts from This corpus is the British counterpart of the Brown Corpus of American English, which contains texts printed in the same year, so that comparison between both varieties could be made.

24 The British National Corpus (BNC) is a 100 million-word collection of samples of written and spoken language from a wide range of sources, designed to represent a wide cross-section of current British English, both spoken and written.

25 The written part (90%) The written part (90%) includes extracts from regional and national newspapers, specialist periodicals and journals for all ages and interests, academic books and popular fiction, published and unpublished letters and memoranda, school and university essays, among many other kinds of text. The spoken part (10%) The spoken part (10%) includes a large amount of unscripted informal conversation, recorded by volunteers selected from different age, region and social classes in a demographically balanced way, together with spoken language collected in all kinds of different contexts, ranging from formal business or government meetings to radio shows and phone-ins.

29 The Bank of English (BoE) started by John Sinclair, was launched in 1991 by COBUILD (a division of HarperCollins Publishers) and The University of Birmingham. This huge collection is composed of a wide range of different types of writing and speech. It contains samples of the English language from hundreds of different sources. Written texts come from newspapers, magazines, fiction and non-fiction books, brochures, leaflets, reports, letters, and so on. Spoken texts are represented by transcriptions of everyday casual conversation, radio broadcasts, meetings, interviews and discussions, etc. The material is up- to-date, with the majority of texts originating after Taken together the Bank of English provides objective evidence about the English which most people read, write, speak and hear every day of their lives.

30 The MICASE corpus is a spoken language corpus of approximately 1.7 million words (190 hours) focusing on contemporary university speech within the microcosm of the University of Michigan, in Ann Arbor, Michigan. This is a typical large public research university with about 37,000 students, approximately one-third of whom are graduate students. Speakers represented in the corpus include faculty, staff, and all levels of students, and both native and non-native speakers.

31 The American National Corpus (ANC) project is creating a massive electronic collection of American English, including texts of all genres and transcripts of spoken data produced from 1990 onward. The ANC will provide the most comprehensive picture of American English ever created, and will serve as a resource for education, linguistic and lexicographic research, and technology development. When completed, the ANC will contain a core corpus of at least 100 million words, comparable across genres to the BNC. Beyond this, the corpus will include an additional component of potentially several hundreds of millions of words, chosen to provide both the broadest and largest selection of texts possible.

32 You can access CORIS/CODIS (CORpus di Italiano Scritto) at CORIS/CODIS has been available since September It consists of 100 million words and it is up-dated every two years. It is composed of a collection of authentic texts, in electronic format, designed to be representative of a wide cross-section of current Italian.

35 Which language should a translator only translate into? The Code of Professional Ethics of the Translators’ Guild of Great Britain states: A translator shall work only into the language (in exceptional cases this may include a second language) of which he has native knowledge. ‘Native knowledge’ is defined as the ability to speak and write a language so fluently that the expression of thought is structurally, grammatically and idiomatically correct.
