Найти книгу: "Practical Text Mining with Perl"

Provides readers with the methods, algorithms, and means to perform text mining tasks This book is devoted to the fundamentals of text mining using Perl, an open-source programming tool that is freely available via the Internet (www.perl.org). It covers mining ideas from several perspectives–statistics, data mining, linguistics, and information retrieval–and provides readers with the means to successfully complete text mining tasks on their own. The book begins with an introduction to regular expressions, a text pattern methodology, and quantitative text summaries, all of which are fundamental tools of analyzing text. Then, it builds upon this foundation to explore: Probability and texts, including the bag-of-words model Information retrieval techniques such as the TF-IDF similarity measure Concordance lines and corpus linguistics Multivariate techniques such as correlation, principal components analysis, and clustering Perl modules, German, and permutation tests Each chapter is devoted to a single key topic, and the author carefully and thoughtfully introduces mathematical concepts as they arise, allowing readers to learn as they go without having to refer to additional books. The inclusion of numerous exercises and worked-out examples further complements the book's student-friendly format. Practical Text Mining with Perl is ideal as a textbook for undergraduate and graduate courses in text mining and as a reference for a variety of professionals who are interested in extracting information from text documents.

It shows how PHP can be used to design and develop highly manageable and secure applications to solve practical problems.

В книге представлены наиболее актуальные направления в области разработки корпоративных систем: организация хранилищ данных, оперативный (OLAP) и интеллектуальный анализ данных (Data Mining). Все три направления рассмотрены в достаточном для понимания и дальнейшего использования на практике объеме. Описание методов и алгоритмов анализа данных и иллюстрация их работы на примерах позволит использовать книгу не только как учебное пособие, но и как практическое руководство при разработке программного обеспечения.

Книга является вторым, обновленным и дополненным, изданием учебного пособия «Методы и модели анализа данных: OLAP и Data Mining». Излагаются основные направления в области разработки корпоративных систем: организация хранилищ данных, распределенный, оперативный (OLAP), интеллектуальный (Data Mining), визуальный (Visual Mining) и текстовый (Text Mining) анализ данных. Приведено описание методов и алгоритмов решения основных задач анализа: классификации, кластеризации и др. Описание идеи каждого метода дополняется конкретным примером его применения. Для студентов и специалистов в области анализа данных.

The question about the source of additional income has always been central in identifying the essence of entrepreneurship. For the study of any dynamical and structural extensive system requires a lot of intellectual effort. Having learned the essence, identifying potential internal and external display can clearly represent the structure and dynamics of the phenomena deduced. Specifying the study by examining the individual elements, and identifying cause-effect relationship of the dynamic state of the phenomenon and the world around him. International entrepreneurship as a phenomenon involved in the activity in many areas of society. The knowledge of his nature will allow all stakeholders to harmonize the internal mental processes and environmental reality. The consumer uses to access the world's goods. The entrepreneur is critical and represents their innovative ideas. Businessman realizes in practice commercial projects. The State creates conditions for personal development and political and economic means affect the cross-border commodity and cash flows, international payments.
