Natural Language Processing (or Text Analytics/Text Mining) applies analytic tools to learn from collections of text data, like social media, books, newspapers, emails, etc. The goal can be considered to be similar to humans learning by reading such material. However, using automated algorithms we can learn from massive amounts of text, very much more than a human can. It is bringing a new revolution by giving rise to chatbots and virtual assistants to help one system address queries of millions of users. NLP is a branch of artificial intelligence that has many important implications on the ways that computers and humans interact. Human language, developed over thousands and thousands of years, has become a nuanced form of communication that carries a wealth of information that often transcends the words alone. NLP will become an important technology in bridging the gap between human communication and digital data. --------------------------------- For more information, please write back to us at [email protected] or call us at IND: 9606058406 / US: 18338555775 (toll-free).

Natural Language Processing With Python and NLTK p.1 Tokenizing words and Sentences
Natural Language Processing is the task we give computers to read and understand (process) written text (natural language). By far, the most popular toolkit or API to do natural language processing is the Natural Language Toolkit for the Python programming language. The NLTK module comes packed full of everything from trained algorithms to identify parts of speech to unsupervised machine learning algorithms to help you train your own machine to understand a specific bit of text. NLTK also comes with a large corpora of data sets containing things like chat logs, movie reviews, journals, and much more! Bottom line, if you're going to be doing natural language processing, you should definitely look into NLTK!

SQLizer: Query Synthesis from Natural Language
Navid Yaghmazadeh, Yuepeng Wang, Isil Dillig, Thomas Dillig This paper presents a new technique for automatically synthesizing SQL queries from natural language (NL). At the core of our technique is a new NL-based program synthesis methodology that combines semantic parsing techniques from the NLP community with type-directed program synthesis and automated program repair. Starting with a program sketch obtained using standard parsing techniques, our approach involves an iterative refinement loop that alternates between probabilistic type inhabitation and automated sketch repair. We use the proposed idea to build an end-to-end system called SQLIZER that can synthesize SQL queries from natural language. Our method is fully automated, works for any database without requiring additional customization, and does not require users to know the underlying database schema. We evaluate our approach on over 450 natural language queries concerning three different databases, namely MAS, IMDB, and YELP. Our experiments show that the desired query is ranked within the top 5 candidates in close to 90% of the cases and that SQLIZER outperforms NALIR, a state-of-the-art tool that won a best paper award at VLDB'14.

Amazing Things NLP Can Do!
In this video I want to highlight a few of the awesome things that we can do with Natural Language Processing or NLP. NLP basically means getting a computer to understand text and help you with analysis. Some of the major tasks that are a part of NLP include: · Automatic summarization · Coreference resolution · Discourse analysis · Machine translation · Morphological segmentation · Named entity recognition (NER) · Natural language generation · Natural language understanding · Optical character recognition (OCR) · Part-of-speech tagging · Parsing · Question answering · Relationship extraction · Sentence breaking (also known as sentence boundary disambiguation) · Sentiment analysis · Speech recognition · Speech segmentation · Topic segmentation and recognition · Word segmentation · Word sense disambiguation · Lemmatization · Native-language identification · Stemming · Text simplification · Text-to-speech · Text-proofing · Natural language search · Query expansion · Automated essay scoring · Truecasing Let’s discuss some of the cool things NLP helps us with in life 1. Spam Filters – nobody wants to receive spam emails, NLP is here to help fight span and reduce the number of spam emails you receive. No it is not yet perfect and I’m sure we still all still receive some spam emails but imagine how many you’d get without NLP! 2. Bridging Language Barriers – when you come across a phrase or even an entire website in another language, NLP is there to help you translate it into something you can understand. 3. Investment Decisions – NLP has the power to help you make decisions for financial investing. It can read large amounts of text (such as news articles, press releases, etc) and can pull in the key data that will help make buy/hold/sell decisions. For example, it can let you know if there is an acquisition that is planned or has happened – which has large implications on the value of your investment 4. Insights – humans simply can’t read everything that is available to us. NLP helps us summarize the data we have and pull out meaningful information. An example of this is a computer reading through thousands of customer reviews to identify issues or conduct sentiment analysis. I’ve personally used NLP for getting insights from data. At work, we conducted an in depth interview which included several open ended response type questions. As a result we received thousands of paragraphs of data to analyze. It is very time consuming to read through every single answer so I created an algorithm that will categorize the responses into one of 6 categories using key terms for each category. This is a great time saver and turned out to be very accurate. Please subscribe to the YouTube channel to be notified of future content!

Claire Kelley, Sarah Kelley - Automatic Citation generation with Natural Language Processing
Description Can citations write themselves? Using a topic modeling approach we model similarity between patents from the US patent database via cosine similarity. Mining the text of millions of patents for similarities allows us to algorithmically recommend possible citations for new patents. We use python, pyspark and big query to parallelize complex operations over millions of rows of data. Abstract In this project we use natural language processing to investigate ways to generate recommendations for citations for new patents. Using a topic modeling approach and cosign similarity we attempt to recommend patents similar to the text of a potential new patent. This would allow inventors and engineers to quickly reference patents similar to their own and easily cite them. From an architectural stand point we use big query to handle data ingestion and pre-processing. The data management functionality of big query is key because there are millions of patents some of which may contain hundreds of pages of text. After pre processing in big query the bulk of our analytic work is done in spark through the python wrapper which allows for easy parallelization of the analytical portion. www.pydata.org PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States.

Jiwon Seo - SociaLite Python integrated Query Lamguage for Big Data Analysis
PyData SV 2014 SociaLite is a Python-integrated query language for big data analysis. It makes big data analysis simple, yet achieves fast performance with its compiler optimizations, often more than three orders of magnitude faster than Hadoop MapReduce programs. For example, PageRank algorithm can be implemented in just 2 lines of SociaLite query, which runs nearly as fast as an optimal C implementation. High-level abstractions in SociaLite help implement distributed data analysis algorithms. For example, its distributed in-memory tables allow large data to be stored across multiple machines, and with minimal user annotations, fast distributed join operations can be performed. Moreover, its Python integration makes SociaLite very powerful. We support embedding and extending, where embedding supports using SociaLite queries directly in Python code, and extending supports using Python functions in SociaLite queries. To support embedding, we apply source code rewriting that transforms SociaLite queries to invoke SociaLite runtime interfaces. For extending, we keep track of functions defined in Python interpreter and make them accesible from SociaLite. The integration makes it easy to implement various data mining algorithms in SociaLite and Python. I will demonstrate in the talk a few well-known algorithms implemented in SociaLite, including PageRank, k-means, and logistic regression. The high-level queries can achieve fast performance with various optimizations. The queries are compiled into Java bytecode with compiler optimizations applied, such as prioritizations or pipelined evaluation. Also, the runtime system gives its best effort to achieve full utilizations of multi-core processors as well as network bandwidths. With the compiler optimizations and the runtime system we achieve very fast performance that is often close to optimal C implementations.

Learn Excel - Sentiment Analysis - Podcast 2062
It is easy to quantify survey data when it is multiple choice You can use a pivot table to figure out what percentage each answer has But what about free-form text answers? These are hard to process if you have hundreds or thousands of them. Sentiment Analysis is a machine-based method for predicting if an answer is positive or negative. Microsoft offers a tool that does Sentiment Analysis in Excel - Azure Machine Learning. Traditional sentiment analysis requires a human to analyze and categorize 5% of the statements. Traditional sentiment analysis is not flexible - you will rebuild the dictionary for each industry. Excel uses MPQA Subjectivity Lexicon (read about that at http://bit. ly/1SRNevt) This generic dictionary includes 5,097 negative and 2,533 positive words Each word is assigned a strong or weak polarity This works great for short sentences, such as Tweets or Facebook posts It can get fooled by double-negatives To install, go to Insert, Excel Store, search for Azure Machine Learning Specify an input range and two blank columns for the output range. The heading for the input range has to match the schema: tweet_text Companion article at: http://sfmagazine.com/post-entry/may-2016-excel-sentiment-analysis/

Perform a Lookup with Power Query
Check out my Blog: http://exceltraining101.blogspot.com This video show how to use Power Query to perform lookups. For small data sets you are better off with Excel's other lookup function, but if you are dealing with large data sets (over half a million) you may be better off using Power Query. This method also would make it easier if you do this on a recurring basis (daily, weekly, etc) and didn't/couldn't write macros. P.S. Feel free to provide a comment or share it with a friend! --------------------- #exceltips #exceltipsandtricks #exceltutorial #doughexcel --------------------- Excel Training: https://www.exceltraining101.com/p/training.html Excel Books: https://www.amazon.com/shop/dough

Topic Extraction with MeaningCloud and Graphileon (Neo4j Online Meetup #47)
Topic extraction is very often a crucial step in Natural Language Processing. It results in lists of entities, concepts, phrases, numbers that often are the input for further processes, used for Competitive Intelligence, Social Media Analysis and Search and Content Recommendation. The items that are extracted are very diverse. Often they are also densely connected. These characteristics are in the sweet spot of graph databases, and more precisely in graph databases that use a property graph model, because these offer the possibility to add other that results from post-processing, like similarity coefficients, sentiment scores and user-ratings. During the meetup , Tom Zeppenfeldt will illustrate how the Graphileon platform can be used to connect various webservices ([NewsApi](https://newsapi.org/) , [Lateral Article Extractor](https://lateral.io/docs/article-extractor) and [MeaningCloud](tps://www.meaningcloud.com) ) to process articles and use Neo4j's Cypher and graph algorithms to find similarities. ----------------------------- ABOUT THE SPEAKER ----------------------------- Tom Zeppenfeldt is founder of Graphileon, supplier of a graph-based application development platform. After a career in international development, a sector in which information requirements change rapidly, he started developing tools that allowed non-developers to explore data sets and build flexible applications. ----------------------------- ONLINE DISCUSSIONS ----------------------------- We'll be taking questions live during the session, but if you have any questions before or after be sure to post them in the project's thread in the Neo4j Community Site (https://community.neo4j.com/t/topic-extraction-with-meaning-cloud-and-graphileon-online-meetup/4332). ----------------------------- TIME ----------------------------- 08:00 PST (UTC - 8 hours) 11:00 EST (UTC - 5 hours) 16:00 UTC 16:00 GMT (UTC + 00 hours) 17:00 CET (UTC + 1 hours) ---------------------------------------------------------------------------------------- WANT TO BE FEATURED IN OUR NEXT NEO4J ONLINE MEETUP? ---------------------------------------------------------------------------------------- We select talks from our Neo4j Community site! community.neo4j.com To submit your talk, post in in the #projects (if including a link to github or website) or #content (if linking to a blog post, slideshow, video, or article) categories. ------------------------------------------------------------------------- VOTE FOR THE PRESENTATIONS YOU'D LIKE TO SEE! ------------------------------------------------------------------------- 'VOTE' for the projects and content you'd like to see!
