Explorations in Automatic Thesaurus Discovery


Book Description

Explorations in Automatic Thesaurus Discovery presents an automated method for creating a first-draft thesaurus from raw text. It describes natural processing steps of tokenization, surface syntactic analysis, and syntactic attribute extraction. From these attributes, word and term similarity is calculated and a thesaurus is created showing important common terms and their relation to each other, common verb--noun pairings, common expressions, and word family members. The techniques are tested on twenty different corpora ranging from baseball newsgroups, assassination archives, medical X-ray reports, abstracts on AIDS, to encyclopedia articles on animals, even on the text of the book itself. The corpora range from 40,000 to 6 million characters of text, and results are presented for each in the Appendix. The methods described in the book have undergone extensive evaluation. Their time and space complexity are shown to be modest. The results are shown to converge to a stable state as the corpus grows. The similarities calculated are compared to those produced by psychological testing. A method of evaluation using Artificial Synonyms is tested. Gold Standards evaluation show that techniques significantly outperform non-linguistic-based techniques for the most important words in corpora. Explorations in Automatic Thesaurus Discovery includes applications to the fields of information retrieval using established testbeds, existing thesaural enrichment, semantic analysis. Also included are applications showing how to create, implement, and test a first-draft thesaurus.




A Number


Book Description

A fascinating meditation on human cloning, personal identity and the conflicting claims of nature and nurture. Bernard thought he was an only child. One day he learns the shocking truth: he is just one of a number of clones. Together, he and his father confront epic questions of identity, intimacy and belonging. Caryl Churchill's play A Number pushes the boundaries of science and ethics with an astonishing twist on the dynamics of the father/son relationship. It was originally produced at the Royal Court Theatre, London, in 2002, winning the Evening Standard Award for Best Play.




Math You Can Play Combo


Book Description

Math Your Kids WANT to Do. You’ll love these math games because they give your child a strong foundation for mathematical success. By playing these games, you strengthen your child’s intuitive understanding of numbers and build problem-solving strategies. Mastering a math game can be hard work. But kids do it willingly because it’s fun. Math You Can Play Combo features two books in one, with 42 kid-tested games that offer a variety of challenges for preschool and school-age learners. Chapters include: • Early Counting: Practice subitizing — recognizing small numbers of items at a glance—and learn the number symbols. • Childhood Classics: Traditional folk games invite the whole family to enjoy playing with math. • Number Bonds: Build a mental picture of the relationships between numbers as you begin to explore addition. • Numbers to One Hundred: Develop mental math skills for working with larger numbers. Practice using place value, addition, and subtraction. • Mixed Operations: Give mental muscles a workout with games that require number skills and logical thinking. • Logic and Probability: Logic games sharpen inductive and deductive thinking skills, while games of chance build an intuition for probability. Math games prevent math anxiety. Games pump up your child’s mental muscle, reduce the fear of failure, and generate a positive attitude toward mathematics. Parents can use these games to enjoy quality time with your children. Classroom teachers like them as warm-ups and learning center activities or for a relaxing review day at the end of a term. If you are a tutor or homeschooler, make games a regular feature in your lesson plans to build your students’ math skills. So what are you waiting for? Clear off a table, grab a deck of cards, and let's play some math!




Work Play


Book Description

This book is designed to provide Human Resource Development program designers, workshop presenters, facilitators, and consultants with creative, structured learning experiences and detailed guidance on how to use them for effective training, conferences, and workshops. It is a practical handbook containing 36 varied and versatile activities that cover a comprehensive range of learning themes. Although these activities are particularly well suited to team building, group problem solving, and leadership training, they can be used for communication, decision making, creativity, resource management, and a multitude of other learning purposes. Their flexibility, in terms of fit with a broad spectrum of training agendas, makes them particularly useful. Each activity can serve a range of training needs and agendas. Each activity has applicability to a variety of learning themes, some of which can be explored in depth using the activity alone or in conjunction with suggested companion exercises. They can be implemented either at different times for different purposes or used singularly to accomplish a 'variety of related learning objectives.

A Disappearing Number


Book Description

A Disappearing Number takes as its starting point the story of one of the most mysterious and romantic mathematical collaborations of all time. Simultaneously a narrative and an enquiry, the production crosses three continents and several histories, to weave a provocative theatrical pattern about our relentless compulsion to understand. A man mourns the loss of his lover, a mathematician mourns her own fate. A businessman travels from Los Angeles to Chennai pursuing the future; a physicist in CERN looks for it too. The mathematician G.H. Hardy seeks to comprehend the ideas of the genius Srinivasa Ramanujan in the chilly English surroundings of Cambridge during the First World War. Ramanujan looks to create some of the most complex mathematical patterns of all time. Threaded through this pattern of stories and ideas are questions. About mathematics and beauty; imagination and the nature of infinity; about what is continuous and what is permanent; how we are attached to the past and how we affect the future; how we create and how we love. The book features an essay by Marcus du Sautoy, Professor of Mathematics at Wadham College, Oxford, and an introduction by Simon McBurney. The Complicité production was an astonishing success during its run at the Barbican, London in Spring 2007, winning The Evening Standard's Best New Play Award 2007. Called ' Mesmerizing' by the New York Times, 'A Disappearing Number' is a brilliant play, aided with original music composed by the award winning DJ, producer and writer Nitin Sawhney. 'A Disappearing Number' was revived at the Novello Theatre, London in autumn 2010.




On Numbers and Games


Book Description

Originally written to define the relation between the theories of transfinite numbers and mathematical games, the resulting work is a mathematically sophisticated but eminently enjoyable guide to game theory. By defining numbers as the strengths of positions in certain games, the author arrives at a new class that includes both real numbers and ordinal numbers: surreal numbers. The second edition presents developments in mathematical game theory, focusing on surreal numbers and the additive theory of partizan games.
