This book starts off by laying the foundation for Natural Language Processing and why Python is one of the best options to build an NLP-based expert system with advantages such as Community support, availability of frameworks and so on. Later it gives you a better understanding of available free forms of corpus and different types of dataset. After this, you will know how to choose a dataset for natural language processing applications and find the right NLP techniques to process sentences in datasets and understand their structure. You will also learn how to tokenize different parts of sentences and ways to analyze them. During the course of the book, you will explore the semantic as well as syntactic analysis of text. You will understand how to solve various ambiguities in processing human language and will come across various scenarios while performing text analysis. You will learn the very basics of getting the environment ready for natural language processing, move on to the initial setup, and then quickly understand sentences and language parts. You will learn the power of Machine Learning and Deep Learning to extract information from text data.By the end of the book, you will have a clear understanding of natural language processing and will have worked on multiple examples that implement NLP in the real world.

Python is the most widely used language for natural language processing (NLP) thanks to its extensive tools and libraries for analyzing text and extracting computer-usable data. This book will take you through a range of techniques for text processing, from basics such as parsing the parts of speech to complex topics such as topic modeling, text classification, and visualization.Starting with an overview of NLP, the book presents recipes for dividing text into sentences, stemming and lemmatization, removing stopwords, and parts of speech tagging to help you to prepare your data. You’ll then learn ways of extracting and representing grammatical information, such as dependency parsing and anaphora resolution, discover different ways of representing the semantics using bag-of-words, TF-IDF, word embeddings, and BERT, and develop skills for text classification using keywords, SVMs, LSTMs, and other techniques. As you advance, you’ll also see how to extract information from text, implement unsupervised and supervised techniques for topic modeling, and perform topic modeling of short texts, such as tweets. Additionally, the book shows you how to develop chatbots using NLTK and Rasa and visualize text data.By the end of this NLP book, you’ll have developed the skills to use a powerful set of tools for text processing.

Python ninja. 70 sekretnych receptur i taktyk programistycznych
Cody Jackson
Python jest językiem, którego można się nauczyć stosunkowo łatwo - a potem dość szybko przejść do praktyki. To duża zaleta: nic tak nie motywuje do dalszej pracy, jak pierwsze sukcesy na wczesnym etapie. Niemniej wielu nawet dość doświadczonych programistów Pythona nie wykorzystuje najlepszych cech tego języka. Ich aplikacje mogłyby być bardziej niezawodne, a kod - czystszy. Co gorsza, wiele ze znakomitych narzędzi i technologii powiązanych z Pythonem nie przebiło się do ogólnej świadomości społeczności skupionej wokół języka, przez co nie wykorzystuje się w pełni ich możliwości. Celem tej książki jest rozwiązanie tego problemu. To rzecz przeznaczona dla programistów Pythona, którzy chcą znacząco poprawić jakość swoich aplikacji. Wyjaśniono tu mało znane lub błędnie rozumiane aspekty implementacji modułów standardowej biblioteki Pythona. Starannie opisano dekoratory, menedżery kontekstu, współprogramy i generatory oraz szczegóły wewnętrznego działania metod specjalnych. Pokazano alternatywne powłoki interaktywne, które mogą okazać się dużym ułatwieniem podczas kodowania. Ciekawym elementem książki jest prezentacja projektu PyPy, dzięki któremu można zapewnić współbieżność kodu. Nie zabrakło przydatnych informacji o tworzeniu dokumentacji kodu Pythona. Dzięki tej książce między innymi: zrozumiesz różnice między plikami .py i .pyc wykorzystasz współprogramy do symulowania wielowątkowości zastosujesz moduł decimal do lepszego prowadzenia działań na liczbach zmiennoprzecinkowych zgłębisz tajniki podinterpreterów poprawiających współbieżność w Pythonie poprawisz funkcjonalność programu za pomocą dekoratorów Python - łatwiejszy, niż sądzisz, potężniejszy, niż myślisz!

Python nie jest językiem idealnym, jednak przybywa programistów, którzy uważają go za bliski ideału. Wyróżnia się prostotą i wszechstronnością. Jest wdzięcznym narzędziem do badania danych i tworzenia systemów sztucznej inteligencji, uwielbiają go analitycy, ekonomiści i naukowcy. Może posłużyć do tworzenia stron WWW czy aplikacji specjalnego przeznaczenia. Python należy do najbardziej spójnych i czytelnych języków programowania. Jest przykładem całkiem udanego kompromisu pomiędzy prostotą, łatwością przyswajania i wyjątkową skutecznością. Z pewnością warto się go nauczyć, jednak od początku dobrze jest wpoić sobie nawyki pisania kodu nowoczesnego, wysokiej jakości, zgodnego z dobrą praktyką. Oto znakomity, przystępny i świetnie napisany podręcznik do nauki Pythona. Opisuje podstawy kodu i struktur danych i stopniowo wprowadza bardziej zaawansowane zagadnienia, takie jak praca z bazami danych i stronami WWW, podstawy działania chmury obliczeniowej, uczenia maszynowego i strumieniowania zdarzeń. Poza standardową biblioteką Pythona przedstawiono tu przydatne zewnętrzne pakiety, dokładniej opisano te najbardziej pomocne. Omówiono dobre praktyki tworzenia, testowania i diagnozowania kodu. Książka zawiera też mnóstwo wskazówek i przykładów kodu. Wyjaśnia pewne szczególne funkcjonalności Pythona, których stosowanie jest o wiele lepszym rozwiązaniem niż adaptowanie technik z innych języków. Nawet jeśli dziś o programowaniu wiesz mniej niż niewiele, dzięki temu podręcznikowi staniesz się prawdziwym pythonowcem! W tej książce między innymi: podstawy Pythona oraz funkcje, moduły i pakiety programowanie zorientowane obiektowo praca z bazami danych: relacyjnymi i NoSQL klienty internetowe, serwery, interfejsy API i usługi zarządzanie programami, procesami i wątkami implementacja współbieżności i komunikacji sieciowej Problemy? Rozwiąż je po pythonowsku!
