问答题决策树法

问答题决策树法（Question-Answering Decision Tree Method）是一种基于决策树的问答系统技术。

下面是该方法的一般步骤：
1. 数据收集：收集用于构建问答系统的相关数据，包括问题和对应的答案。

这些数据可以来自各种来源，如知识库、文档或者预先准备的问答数据集。

2. 特征提取：根据问题和答案，提取有关特征，用于构建决策树。

这些特征可以是问题的关键词、上下文信息、问题类型等。

3. 构建决策树：使用已收集的问题和答案数据集来建立决策树模型。

决策树是一种树状结构，每个节点代表一个问题或特征，每个分支代表一个可能的答案或决策。

4. 决策和回答：根据用户输入的问题，通过决策树逐步向下进行，直到叶子节点，然后返回对应的答案。

5. 优化和训练：根据系统使用过程中的反馈和用户对答案的评价，不断优化和更新决策树模型。

可以使用机器学习算法来训练决策树，提高问答系统的准确性和效率。

问答题决策树法是一种简单而直观的问答系统建模方法，可以根据问题的特征逐步进行决策，达到回答问题的目的。

然而，它可能过于依赖预定义的问题和答案数据集，对于未知问题的处理可能有限。

因此，在实际使用中，需要根据具体情况对模型进行优化和改进。

Y ou may not use any of the words in the bank more than once.We all know there exists a great void (空白) in the public educational system when it comesto 26 to STEM (Science, Technology, Engineering and Mathematics) courses. One educator named Dori Roberts decided to do something to change this system. Dori taught high school engineering for 11 years. She noticed there was a real void in quality STEM education at all 27 of the public educational system. She said, “I started Engineering For Kids (EFK) after noticing a real lack of math, science and engineering programs to 28 my own kids in.”She decided to start an afterschool program where children 29 in STEM-based competitions. The club grew quickly and when it reached 180 members and the kids in the program won several state 30, she decided to devote all her time to cultivating and 31 it. The global business EFK was born.Dori began operating EFK out of her Virginia home, which she then expanded to 32 recreation centers. Today, the EFK program 33 over 144 branches in 32 states within the United States and in 21 countries. Sales have doubled from $ 5 million in 2014 to $ 10 million in 2015, with 25 new branches planned for 2016. The EFK website states, “Our nation is not 34 enough engineers. Our philosophy is to inspire kids at a young age to understand that engineering is a great 35.”Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. Y ou may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Why aren’t you curious about what happened?A) “You suspended Ray Rice after our video.” a reporter from TMZ challenged National Football League Commissioner Roger Goodell the other day. “Why didn’t yo u have the curiosity to go to the casino(赌场) yourself ?”The implication of the question is that a more curious commissioner would have found a way to get the tape.B) The accusation of incuriosity is one that we hear often. Carrying the suggestion that there is something wrong with not wanting to search out the truth. “I have been bothered for a long time about the curious lack of curiosity.” said a Democratic member of the New Jersey legislature back in July, referring to an insufficiently inquiring attitude on the part of an assistant to New Jersey Governor Chris Christie who chose not to ask hard questions about the George Washington Bridge traffic scandal. “Isn’t the mainstream media the least bit curious about what happened?” wrote conservative writer Jennifer Rubin earlier his year, referring to the attack on Americans in Benghazi, Libya.C) The implication, in each case, is that curiosity is a good thing, and a lack of curiosity is a problem. Are such accusations simply efforts to score political points for one’s party? Or is there something of particular value about curiosity in and of itself?D) The journalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Your Future Depends on It, insists that the answer to that last question is “Yes”. Leslie argues that curiosity is a much-overlooked human virtue, crucial to our success, and that we are losing it.E) We are suffering, he writes, from a “serendipity deficit.” The word “serendipity” was coined by Horace Walpole in an 1854 letter, from a tale of three princes who “were always making discoveries, by accident, of things they were not in search of.” Leslie worries that the rise of he Internet, among other social and technological changes, has reduced our appetite for aimless adventures. No longer have we the inclination to let ourselves wander through fields of knowledge, ready to be surprised. Instead, we seek only the information we want.F) Why is this a problem? Because without curiosity we will lose the spirit of innovation and entrepreneurship. We will see unimaginative governments and dying corporations make disastrous decisions. We will lose a vital part of what has made humanity as a whole so successful as a species.G) Leslie presents considerable evidence for the proposition that the society as a whole is growing less curious. In the U. S. and Europe, for example, the rise of the Internet has led to a declining consumption of news from outside the reader’s borders. But not everything is to be blamed on technology. The decline in interest in literary fiction is also one of the causes identified by Leslie. Reading literary fiction, they says, makes us more curious.H) Moreover, in order to be curious, “you have to be aware of a gap in your knowledge in the first place.” Although Leslie perhaps paints a bit br oadly in contending that most of us are unaware of how much we don’t know, he’s surely right to point out that the problem is growing: “Google can give us the powerful illusion that all questions have definite answers.”I) Indeed, Google, for which Leslie expresses admiration, is also his frequent whipping boy(替罪羊). He quotes Google co-founder Larry Page to the effect that the “perfect search engine” will “understand exactly what I mean and give me back exactly what I want.” Elsewhere in the book, Leslie writes: “Google aims to save you from the thirst of curiosity altogether.”J) Somewhat nostalgically (怀旧地), he quotes John Maynard Keynes’s justly famous words of praise to the bookstore: “One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as curiosity dictates, should be an afternoon’s entertainment.” If only!K) Citing the work of psychologists and cognitive (认知的) scientists, Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work. Curiosity, he argues, is the third key factor—and a difficult one to preserve. If not cultivated, it will not survive: “Childhood curiosity is a collaboration between child and adult. The surest way to kill it is to leave it alone.”L) School education, he warns, is often conducted in a way that makes children incurious. Children of educated and upper-middle-class parents turn out to be far more curious, even at early ages, than children of working class and lower class families. That lack of curiosity produces a relative lack of knowledge, and the lack of knowledge is difficult if not impossible to compensate for later on.M) Although Leslie’s book isn’t about politics, he doesn’t entirely shy away from the problem. Political leaders, like leaders of other organizations, should be curious. They should ask questions at crucial moments. There are serious consequences, he warns, in not wanting to know.N) He present as an example the failure of the George W.Bush administration to prepare properly for the after-effects of the invasion of Iraq. According to Leslie, those who ridiculed former Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the “unknown unknowns” were mistaken. Rumsfeld’s idea. Leslie writes, “wasn’t absurd—it wassmart.” He adds, “The tragedy is that he didn’t follow his own advice.”O) All of which brings us back to Goodell and the Christie case and Benghazi. Each critic in those examples is charging, in a different way, that someone in authority is intentionally being incurious. I leave it to the reader’s political preference to decide which, if any, charges should stick. But let’s be careful about demanding curiosity about the other side’s weaknesses and remaining determinedly incurious about our own. We should be delighted to pursue knowledge for its own sake—even when what we find out is something we didn’t particularly want to know.36. To be curious, we need to realize first of all that there are many things we d on’t know.37. According to Leslie, curiosity is essential to one’s success.38. We should feel happy when we pursue knowledge for knowledge’s sake.39. Political leaders’ lack of curiosity will result in bad consequences.40. There are often accusations a bout politicians’ and the media’s lack of curiosity to find out the truth.41. The less curious a child is, the less knowledge the child may turn out to have.42. It is widely accepted that academic accomplishment lies in both intelligence and diligence.43. Visiting a bookshop as curiosity leads us can be a good way to entertain ourselves.44. Both the rise of the Internet and reduced appetite for literary fiction contribute to people’s declining curiosity.45. Mankind wouldn’t be so innovative without cur iosity.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). Y ou should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call su ch a thing a “disease”.On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.“It unties the hands of the pharmaceutical (制药的) industry so that they can begin treating the disease and not just the side effects,” he said.“Right now, people think of aging as natural and something you can’t control,” he said, “In academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.”But if aging were recognized as a disease, he said, “It would attract fun ding and change the way we do health care. What matters is understanding that aging is curable.”“It was always known that the body accumulates damage.” He added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions.”Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.“There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,” Hayflick said. “Even if those causes of death were eliminated, life expectancy would still no t go much beyond 92 years.”46. What do people generally believe about aging?A) It should cause no alarm whatsoever.B) They just cannot do anything about it.C) It should be regarded as a kind of disease.D) They can delay it with advances in science.47. How do many scientists view aging now?A) It might be prevented and treated.B) It can be as risky as heart disease.C) It results from a vitamin deficiency.D) It is an irreversible biological process.48. What does Alex Zhavoronkov think of “describing aging as a disease”?A) It will prompt people to take aging more seriously.B) It will greatly help reduce the side effects of aging.C) It will free pharmacists from the conventional beliefs about aging.D) It will motivate doctors and pharmacists to find ways to treat aging.49. What do we learn about the medical community?A) They now have a strong interest in research on aging.B) They differ from the academic circles in their view on aging.C) They can contribute to people’s health only to a limited e xtent.D) They have ways to intervene in people’s aging process.50. What does Professor Leonard Hayflick believe?A) The human lifespan cannot be prolonged.B) Aging is hardly separable from disease.C) Few people can live up to the age of 92.D) Heart disease is the major cause of aging.Passage TwoQuestions 51 to 55 are based on the following passage.Female applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts ChristopherIntagliata reports.As is many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring (指导), and have better odds of being hired. Studies show they’re also perceived as more competent than women is STEM (Science, Technology, Engineering, and Mathematics) fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too.“Say, you know, this is the best student I’ve ever had,” sa ys Kuheli Dutt, a social scientist and diversity officer at Columbia University’s Lamont campus. “Compare those excellent letters with a merely good letter: ‘The candidate was productive, or intelligent, or a solid scientist or something that’s clearly solid praise,’ but nothing that singles out the candidate as exceptional or one of a kind.”Dutt and her colleagues studied more than 1,200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared with their male counterparts. That includes letters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt say they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than outstanding letters of recommendation.“We’re not trying to assign blame or criticize anyone or ca ll anyone consciously sexist. Rather, the point is to use the results of this study to open up meaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level,” which may lead to some recommendations for the letter writers themselves.51. What do we learn about applicants to postdoctoral positions in geosciences?A) There are many more men applying than women.B) Chances for women to get the positions are scarce.C) More males than females are likely to get outstanding letters of recommendation.D) Male applicants have more interest in these positions than their female counterparts.52. What do studies about men and women in scientific research show?A) Women engaged in postdoctoral work are quickly catching up.B) Fewer women are applying for postdoctoral positions due to gender bias.C) Men are believed to be better able to excel in STEM disciplines.D) Women who are keenly interested is STEM fields are often exceptional.53. What do the studies find about the recommendation letters for women applicants?A) They are hardly ever supported by concrete examples.B) They contain nothing that distinguishes the applicants.C) They provide objective information without exaggeration.D) They are often filled with praise for exceptional applicants.54. What did Dutt and her colleagues do with the more than 1,200 letters of recommendation?A) They asked unbiased scholars to evaluate them.B) They invited women professionals to edit them.C) They assigned them randomly to reviewers.D) They deleted all information about gender.55.

Australia's native dung beetles are scrub and woodland dwellers, specialising in coarse marsupial droppings and avoiding the soft cattle dung in which bush flies and buffalo flies breed.In the early 1960s George Bornemissza, then a scientist at the Australian Government's premier research organisation, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), suggested that dung beetles should be introduced to Australia to control dung-breeding flies. Between 1968 and 1982, the CSIRO imported insects from about 50 different species of dung beetle, from Asia, Europe and Africa, aiming to match them to different climatic zones in Australia. Of the 26 species that are known to have become successfully integrated into the local environment, only one, an African species released in northern Australia, has reached its natural boundary.Introducing dung beetles into a pasture is a simple process: approximately 1,500 beetles are released, a handful at a time, into fresh cow pats2 in the cow pasture. The beetles immediately disappear beneath the pats digging and tunnelling and, if they successfully adapt to their new environment, soon become a permanent, self- sustaining part of the local ecology. In time they multiply and within three or four years the benefits to the pasture are obvious.Dung beetles work from the inside of the pat so they are sheltered from predators such as birds and foxes. Most species burrow into the soil and bury dung in tunnels directly underneath the pats, which are hollowed out from within. Some large species originating from France excavate tunnels to a depth of approximately 30 cm below the dung pat. These beetles make sausage-shaped brood chambers along the tunnels. The shallowest tunnels belong to a much smaller Spanish species that buries dung in chambers that hang like fruit from the branches of a pear tree. South African beetles dig narrow tunnels of approximately 20 cm below the surface of the pat. Some surface-dwelling beetles, including a South African species, cut perfectly- shaped balls from the pat, which are rolled away and attached to the bases of plants.For maximum dung burial in spring, summer and autumn, farmers require a variety of species with overlapping periods of activity. In the cooler environments of the state of Victoria, the large French species (2.5 cms long) is matched with smaller (half this size), temperate-climate Spanish species. The former are slow to recover from the winter cold and produce only one or two generations of offspring from late spring until autumn. The latter, which multiply rapidly in early spring, produce two to five generations annually. The South African ball-rolling species, being a sub- tropical beetle, prefers the climate of northern and coastal New South Wales where it commonly works with the South African turning species. In warmer climates, many species are active for longer periods of the year.Dung beetles were initially introduced in the late 1960s with a view to controlling buffalo flies by removing the dung within a day or two and so preventing flies from breeding. However, other benefits have become evident. Once the beetle larvae have finished pupation, the residue is a first-rate source of fertiliser. The tunnels abandoned by the beetles provide excellent aeration and water channels for root systems. In addition, when the new generation of beetles has left the nest the abandoned burrows are an attractive habitat for soil-enriching earthworms. The digested dung in these burrows is an excellent food supply for the earthworms, which decompose it further to provide essential soil nutrients. If it were not for the dung beetle, chemical fertiliser and dung would be washed by rain into streams and rivers before it could beabsorbed into the hard earth, polluting water courses and causing blooms of blue-green algae. Without the beetles to dispose of the dung, cow pats would litter pastures making grass inedible to cattle and depriving the soil of sunlight. Australia's 30 million cattle each produce 10-12 cow pats a day. This amounts to 1.7 billion tonnes a year, enough to smother about 110,000 sq km of pasture, half the area of Victoria.Dung beetles have become an integral part of the successful management of dairy farms in Australia over the past few decades. A number of species are available from the CSIRO or through a small number of private breeders, most of whom were entomologists with the CSIRO's dung beetle unit who have taken their specialised knowledge of the insect and opened small businesses in direct competition with their former employer.第41题Questions 41-45Do the following statements reflect the claims of the writer in Reading Passage 1?In boxes 41-45 on your answer sheet writeYES if the statement reflects the claims of the writerNO if the statement contradicts the claims of the writerNOT GIVEN if it is impossible to say what the writer thinks about thisBush flies are easier to control than buffalo flies.______第42题Four thousand species of dung beetle were initially brought to Australia by the CSIRO.______第43题Dung beetles were brought to Australia by the CSIRO over a fourteen-year period.______第44题At least twenty-six of the introduced species have become established in Australia.______第45题The dung beetles cause an immediate improvement to the quality of a cow pasture.______第46题Questions 46-48Label the tunnels on the diagram below.

Often however, governments act in an even more harmful way. They actually subsidise the exploitation and consumption of natural resources A whole range of policies, from farm- price support to protection for coal-mining do, environmental damage and (often) make no economic sense. Scrapping them offers a two-fold bonus: a cleaner environment and a more efficient economy. Growth and environmentalism can actually go hand in hand, if politicians have the courage to confront the vested interest that subsidies create.Section BNo activity affects more of the earth's surface than farming. It shapes a third of the plant's land area, not counting Antarctica, and the proportion is rising. World food output per head has risen by 4 percent between the 1970s and 1980s mainly as a result of increases increases in yields from land already in cultivation, but also because more land has been brought under the plough. Higher yields have been achieved by increased Irrigation , better crop breeding, and a doubling in the use of pesticides and chemical fertillsers in the 1970s and 1980s.Section CAll these activities may have damaging environmental impacts, For example, land clearing for agriculture is the largest single cause of deforestation; chemical fertillsers and pesticides may contaminate water supplies; more intensive farming and the abandonment of fallow periods tend to exacerbate soil erosion; and the spread of mono- culture and use of high-yielding varieties of crops have been accompanied by the disappearance of old varieties of food plants which might have provided, some insurance against pests or diseases in future. Soil erosion threatens the productivity of land in both rich and poor countries. The United States, where the most careful measurements have been done, discovered in 1982 that about one-fifth of its farmland was losing topsoil at a rate likely to diminish the soil's productivity. The countrys subsequently embarked upon a program to convert 11 per cent of its cropped land to meadow or forest. Topsoil in India and China is vanishing much faster than in AmericaSection DGovernment policies have frequently compounded the environmental damage that farming can cause. In the rich countries, subsidies for growing crops and price supports for farm output drive up the price of land. The annual value of these subsidies is immense; about ＄250 billion, or more than all World Bank lending in the 1980s. To increase the output of crops per acre, a farmer's easiest option is to use more of the most readily available Inputs: fertilisers and pesticides. Fertiliser use doubled in Denmark in the period 1960-1985 and increased in The Netherlands by 150 per cent. The quantity, of pesticides applied. has risen too: by 69 per centin 1975-1984 in Denmark, for example, with a rise of 115 per cent in the frequency of application in the three years from 1981.In the late 1980s and early 1990s some efforts were made to reduce farm subsidies The most dramatic example was that of New Zealand, which scrapped most farm support in 1984 A study of the environmental effects, conducted in 1993, found that the end of fertiliser subsidies had been followed by a fall in fertiliser use (a fall compounded by the decline in world commodity prices, which cut farm incomes), The removal of subsidies also stopped land-clearing and over-stocking, which inthe past had been the principal causes of erosion, Farms began to diversify, The one kind of subsidy whose removal appeared to have been bad for the environment was the subsidy to manage soil erosion, In less enlightened countries, and in the European Union, the trend has been to reduce rather than eliminate subsidies, and to introduce new payments to encourage farmers to treat their land in environmentally friendlier ways, or to leave it fallow, It may sound strange but such payments need to be higher than the existing incentives for farmers to grow food crops, Farmers, however, dislike being paid to do nothing. In several countries they have become interested in the possibility of using fuel produced from crop residues either as a replacement for petrol (as ethanol) or as fuel for power stations (as biomass), Such fuels produce far less carbon dioxide than coal or oil, and absorb carbon dioxide as they grow. They are therefore less likely to contribute to the greenhouse effect. But they are rarely competitive with fossil fuels unless subsidised - and growing them does no environmental harm than other cropsSection EIn poor countries, governments aggravate other sorts of damage. Subsidies for pesticides and artificial fertilisers encourage farmers to use greater quantities than are needed to get the highest economic crop yield. A study by the International Rice Research Institute of pesticide use by farmers in South East Asia found that, with pest-resistant varieties of rice, even moderate applications of pesticide frequently cost farmers more than they saved. Such waste puts farmers on a chemical treadmill: bugs and weeds become resistant to poisons, so next year's poisons must be more lethal. One cost is to human health, Every year some 10,000 people die from pesticide poisoning, almost all of them in the developing countries, and another 400,000 become seriously ill. As for artificial fertilisers, their use world-wide increased by 40 per cent per unit of farmed land between the mid 1970s and late 1980s, mostly in the developing countries. Overuse of fertilisers may cause farmers to stop rotating crops or leaving their land fallow, That, in turn, may make soil erosion worse.Section FA result of the Uruguay Round of world trade negotiations is likely to be a reduction of 36 per cent in the average levels of farm subsidies paid by the rich countries in 1986-1990, Some of the world's food production will move from Western Europe to regions where subsidies are lower ornon-existent, such as the former communist countries and parts of the developing world. Some environmentalists worry about this outcome. It will undoubtedly mean more pressure to convert natural habitat into farmland. But it will also have many desirable environmental effects, The intensity of farming in the rich world should decline, and the use of chemical inputs will diminish, Crops are more likely to be grown In the environments to which they are naturally suited. And more farmers in poor countries will have the money and the incentive to manage their land in ways that are sustainable in the long run. That is important, To feed an increasingly hungry world, farmers need every incentive to use their soil and water effectively and efficiently.第54题Questions 54-68Reading Passage 2 has six sections A-F.Choose the most suitable headings for sections A-D and F from the list of headings below.
