Natural Language Processing With Python and NLTK p.1 Tokenizing words and Sentences
 
19:54
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!

Mobile: (0) 9952649690, Email: [email protected], web: www.jpinfotech.org, Blog: www.jpinfotech.blogspot.com The need for natural language interfaces to database has become increasingly acute as more and more people access information from web browsers. Yet NLI (Natural Language Interface) is only usable if they map natural language questions to SQL queries correctly. Natural Language processing is becoming one of the most active areas in Human-Computer Interaction. It is a branch of AI (Artificial Intelligence) which includes in information retrieval, machine translation and Language analysis. The goal of NLP (Natural Language Processing) is to enable communication between people and computers without requiring to memorization of complex commands and procedures. In other words NLP (Natural Language Processing) is techniques which can make the computer understand the languages naturally used by humans. The main purpose of natural Language Query Processing is for an English sentence to be interpreted by the computer and appropriate action taken. Asking questions to databases in natural language is a very convenient and easy method of data access, especially for casual users who do not understand complicated database query languages such as SQL.

Query Languages for Document Stores by Jan Steemann
 
28:27
NoSQL matters Conference in Cologne, Germany 2013 - Query Languages for Document Stores by Jan Steemann - http://2013.nosql-matters.org/cgn/ SQL is the standard and established way to query relational databases. As the name "NoSQL" suggests, NoSQL databases have gone some other way, coming up with several approaches of querying, e.g. access by key, map/reduce, and even own full-featured query languages. We surely don't want the super-fast key/value store require us to use a full-blown query language and slow us down -- but for several other cases querying using a language can still be convenient. This is especially the case in document stores that have a wide range of use cases and allow us to look at different aspects of the same data. As there isn't yet an established standard for querying document databases, the talk will showcase some of the existing implementations such as UNQL, AQL, and jsoniq. Additionally, related topics such as graph query languages will be covered. Slides are available: http://2013.nosql-matters.org/cgn/wp-content/uploads/2013/05/querylanguages.pdf

Text Analysis in Power BI with Cognitive services with Leila Etaati
 
55:18
Abstract: Data that we collected always is not about numbers and structured data. In any organization, there is a need to analyze the text data such as customer comments, extract the primary purpose of a call from its scripts, detect the language of customer feedback and translate it and so forth. To address this issue, Microsoft Cognitive Services provides a set of APIs, SDKs, and services available to developers to do text analysis without writing R or Python codes. In this session, I will explain what is text analysis such as sentiment analysis, key phrase extraction, Language detection and so forth. Next, the process of text analysis in Power BI using cognitive services will be demonstrated. Follow us on Twitter - https://twitter.com/mspowerbi More questions?

Jiwon Seo - SociaLite Python integrated Query Lamguage for Big Data Analysis
 
40:53
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.

Amazing Things NLP Can Do!
 
03:53
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!

Don’t miss the next DataEngConf in Barcelona: https://dataeng.co/2O0ZUq7 Download slides for this talk: https://goo.gl/FZJZrn Your queries won't run fast if your data is not organized right. Apache Calcite optimizes queries, but can we evolve it so that it can optimize data? We had to solve several challenges. Users are too busy to tell us the structure of their database, and the query load changes daily, so Calcite has to learn and adapt. We talk about new algorithms we developed for gathering statistics on massive database, and how we infer and evolve the data model based on the queries, suggesting materialized views that will make your queries run faster without you changing them. About the speaker: Julian Hyde is an expert in query optimization, in-memory analytics, and streaming. He is the original developer of Apache Calcite, the query planning framework behind Apache Hive, Drill, Kylin and Phoenix, and was also the original developer of the open source Mondrian OLAP engine.

Natural Language Search in Solr, Tommaso Teofili, Sourcesense, Eurocon 2011
 
32:46
Natural Language Search in Solr Presented by Tommaso Teofili, Sourcesense This presentation aims to showcase how to build and implement a search engine which is able to understand a query written in a way much nearer to spoken language than to keyword-based search using Apache Lucene/Solr and Apache UIMA. A system which can recognize semantics in natural language can be very handy for non expert users, e-learning systems, customer care systems, etc. With such a system it's possible to submit queries such as "hotels near Rome" or "people working at Google" without having to manually transform a user entered natural language query to a Lucene/Solr query. The Solr - UIMA integration (since Solr 3.1.0) can help on building such intelligent systems using NLP / Text mining algorithms on documents being indexed and on queries written by the user. This module gives Solr the ability of calling UIMA pipelines when documents are indexed to trigger automatic extraction of metadata (i.e. named entities like people, places, organizations, etc.) using existing and custom algorithms as UIMA analysis engines. The talk will cover: The Solr - UIMA integration Introducing UIMA to Lucene's analysis phase Running existing open source NLP algorithms in Lucene/Solr Orchestrating blocks to build a sample system able to understand natural language queries We'll introduce these points using examples (architectures & code) and a sample demo system.

Basic Excel Business Analytics #32: Power Query Import Multiple Excel Files with Multiple Sheets
 
08:59
Download file from “Highline BI 348 Class” section: https://people.highline.edu/mgirvin/excelisfun.htm Learn how to import multiple Excel workbooks (each with the store name in the file name) with multiple sheets in each workbook (each sheet contains the Sales Rep name) and import the sales data into a proper data set, including a column for the sales rep name (data from the sheet tab names) and a column for the store name (data from file name): 1) (00:04) Download File Information 2) (00:23) Look at Excel Workbooks that need to be imported, including the names of each Sales Rep on each sheet tab. 3) (01:20) Power Query, From File, From Folder, to import files from a folder 4) (02:07) Remove Other Columns, being sure to keep file with File name, which contains the store name. 5) (02:24) Add Column and use Power Query Function called Excel.Workbook, so that we can extract the data from the Excel workbook. 6) (03:13) Use Replace Values feature in Power Query to extract the store name from the file name. 7) (03:47) Remove Content Column 8) (03:54) Expand data Column which will expose the Data Column (Data in Excel Workbook), Item Column (contains sheet name data), Kind Column (contains object information such as: Sheet, Table and Defined Names). 9) (04:12) Filter the Kind Column to remove Tables and Defined Names and keep Sheets only. 10) (04:39) Filter Item column to remove sheets that were not properly named (have default names such as Sheet1, Sheet2). We use the “Does Not Contain” Filter to keep sheets that do not contain the text “sheet”; another way to think about it is: “Filter out sheet tabs that have the text ‘sheet’ in them” 11) (05:15) Amazing results: data from sheet tabs and file names is retained for proper data set. 12) (05:27) Remove columns that are not File Name (Store name), Item (Sales Rep Name) and Data. 13) (05:37) Expand data from Excel Workbooks. 14) (05:42) “Use First Rows As Headers” to promote the Field Names from the first sheet in the first workbook to Field Names. 15) (05:53) Filter out Field names from other Sheet tabs. 16) (06:48) Rename Columns 17) (07:15) Add correct Data Types before importing 18) (07:37) Close and Load To a Table on Existing Sheet 19) (08:11)Summary and Conclusion Download Excel File Not: After clicking on link, Use Ctrl + F (Find) and search for “Highline BI 348 Class” or for the file name as seen at the beginning of the video.

Perform a Lookup with Power Query
 
11:00
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.

Filtering and Consolidation - Chapter 5
 
04:47
Text Mining and Analytics Filtering and Consolidation - Chapter 5 This video tutorials cover major techniques for mining and analyzing text data to discover interesting patterns, extract useful knowledge, and support decision making, with an emphasis on statistical approaches that can be generally applied to arbitrary text data in any natural language with no or minimum human effort. Detailed analysis of text data requires understanding of natural language text, which is known to be a difficult task for computers. However, a number of statistical approaches have been shown to work well for the "shallow" but robust analysis of text data for pattern finding and knowledge discovery. You will learn the basic concepts, principles, and major algorithms in text mining and their potential applications. analytics | analytics tools | analytics software | data analysis programs | data mining tools | data mining | text analytics | strucutred data | unstructured data |text mining | what is text mining | text mining techniques | AQL | Annotation Query Language More Articles, Scripts and How-To Papers on http://www.aodba.com
