“Great movie with a nice story!” What do you think, did the person like the film or hate it? Most of the time it’s easy for us to decide whether the message of a text is positive or negative. But what if you wanted to automate the process of understanding the sentiment? For example, if you have a lot of customers leaving comments, or people publishing movie reviews, you will want to discern the sentiment and find out who is posting positive or negative messages. Sentiment analysis is an important piece of many data analytics use cases. Whether it processes customer feedback, movie reviews, or tweets, sentiment scores often contribute an important piece to describing the whole scenario. These are just some examples of a long list of use cases for sentiment analysis, which includes social media analysis, 360 degree customer views, customer intelligence, competitive analysis and many more. To avoid doing this manually, we apply sentiment analysis and teach an algorithm to understand text and extract the sentiment using Natural Language Processing.

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!

Snorkel (https://hazyresearch.github.io/snorkel/) is a tool that automatically extracts information from unstructured data sources, such as the scientific literature and clinical notes, without using large, labeled training datasets, which are often lacking in biomedicine. In this workshop, participants learned about the Snorkel workflow through brief lectures and hands-on activities. This included: Writing labeling functions using pattern-matching and comparisons against existing dictionaries (e.g., Unified Medical Language System) Fitting and assessing a model to the labeling functions to generate the training data Hearing about examples of problems that can and cannot be addressed with Snorkel

Text mining has a large variety of applications and is becoming used in more businesses for gathering intelligence and providing insight. People are sending text constantly online via social media, chat rooms and blogs. Tapping into this information can help businesses gain an advantage and is increasingly a necessary skill for data analytics. Text mining is a unique data mining problem, dealing with real world data that is often heavy on artefacts, difficult to model and challenging to properly manage. Text mining can be seen as a bit of a dark art that is difficult to learn and gain traction. However some basic strategies can often be applied to get good results quite quickly, and the same basic models appear in many text mining challenges. The scikit-learn project is a library of machine learning algorithms for the scientific python stack (numpy & scipy). It is known for having detailed documentation, a high quality of coding and a growing list of users worldwide. The documentation includes tutorials for learning machine learning as well as the library and is a great place to start for beginners wanting to learn data analytics. There is a strong focus on reusable components and useful algorithms, and the text mining sections of scikit-learn follow the “standard model” of text mining quite well. In this presentation, we will go through the scikit-learn project for machine learning and show how to use it for text mining applications. Real world data and applications will be used, including spam detection on Twitter, predicting the author of a program and determining a user's political bent based on their social media account. PyCon Australia is the national conference for users of the Python Programming Language.

Get the Code here : https://github.com/ajhalthor/text-summarizer Follow me on Twitter : https://twitter.com/ajhalthor Take a look at the original by Shlomi Babluki : http://thetokenizer.com/2013/04/28/build-your-own-summary-tool/ TRANSCRIPT OVERVIEW ALGORITHM 1. Take the full CONTENT and split it into PARAGRAPHS. 2. Split each PARAGRAPH into SENTENCES. 3. Compare every sentence with every other. This is done by Counting the number of common words and then Normalize this by dividing by average number of words per sentence. 4. These intermediate scores/values are stored in an INTERSECTION matrix 5. Create the key-value dictionary - Key : Sentence - Value : Sum of intersection values with this sentence 6. From every paragraph, extract the sentences with the highest score. 7. Sort the selected sentences in order of appearance in the original text to preserve content and meaning. And like that, you have generated a summary of the original text. CLASSES IN JAVA PROJECT 1. Sentence : The entire text is divided into a number of paragraphs and each paragraph is divided into a number of sentences. 2. Paragraph : Every paragraph has a number associated with it and an Array List of sentences. 3. Sentence Comparitor : Compare Sentence objects based on Score 4. SentenceComparatorForSummary : Compare Sentence objects based on position in text. 5. SummayTool : akes care of all the operations from extracting sentences to generating the summary. HOW IS MY SUMMARIZER BETTER THAN THE ORIGINAL ? My text summarizer selects number of sentences from a paragraph depending on the length. This is an improvement over the original text summarizer implementation that only selects 1 sentence per paragraph regardless of length. So, If the author decides to crunch everything into 1 paragraph, then only one sentence would be chosen. In the current implementation, we set it to accept several sentences for larger paragraphs. It delivers cogent summaries for general essays, reviews and publications. RUN THIS PROGRAM $ javac -d bin improved_summary.java $ java -classpath bin improved_summary

This is where we attempt to identify a body of text with some sort of label. To start, we're going to use some sort of binary label. Examples of this could be identifying text as spam or not, or, like what we'll be doing, positive sentiment or negative sentiment.

Extreme classification is a rapidly growing research area focusing on multi-class and multi-label problems involving an extremely large number of labels. Many applications have been found in diverse areas ranging from language modeling to document tagging in NLP, face recognition to learning universal feature representations in computer vision, gene function prediction in bioinformatics, etc. Extreme classification has also opened up a new paradigm for ranking and recommendation by reformulating them as multi-label learning tasks where each item to be ranked or recommended is treated as a separate label. Such reformulations have led to significant gains over traditional collaborative filtering and content-based recommendation techniques. Consequently, extreme classifiers have been deployed in many real-world applications in industry. This workshop aims to bring together researchers interested in these areas to encourage discussion and improve upon the state-of-the-art in extreme classification. In particular, we aim to bring together researchers from the natural language processing, computer vision and core machine learning communities to foster interaction and collaboration.

Talk Slides: https://drive.google.com/open?id=1nm3jU2sjLxoatWTenffraN3a6xt0QEE8 Deep learning is widely use in several cases with a good match and accuracy, as for example images classifications. But when to come to social networks there is a lot of problems involved, for example how do we represent a network in a neural network without lost node correspondence? Which is the best encode for graphs or is it task dependent? Here I will review the state of art and present the success and fails in the area and which are the perspective. Ana Paula is a Research Staff Member in IBM Research - Brazil, currently work with large amount of data to do Science WITH Data and Science OF Data at IBM Research Brazil. My technical interesting are in data mining and machine learning area specially in graph mining techniques for health and finance data. I am engage in STEAM initiatives to help girls and women to go to math/computer/science are. She is also passion for innovation and thus I become a master inventor at IBM.

Presenter(s): Aneesha Bakharia URL: http://2011.linux.conf.au/programme/schedule/view_talk/213 Presenters: Aneesha Bakharia ([email protected]) and Aaron Tan ([email protected]) It is becoming increasingly important to incorporate âcollective intelligenceâ within web, mobile and business intelligence applications. Traditionally the implementation of algorithms capable of adding intelligence to an application either required a highly specialised knowledge of machine learning or was extremely costly. Apache Mahout is one of the first open source and scalable machine learning libraries that seeks to mainstream the use of machine learning. This presentation will focus on providing the audience with a practical understanding of the algorithms included in Apache Mahout and how they can be used to provide insight into the patterns that exist in large amounts of data? Text clustering with the Latent Dirichlet Algorithm will also be covered. The Apache Mahout library consists of scalable machine learning algorithms for data mining tasks that encompass classification (NaÃ¯ve Bayes and Support Vector Machines), clustering (kÂmeans, Expectation Maximization, Mean Shift, Latent Dirichlet Allocation and Hierarchical Clustering), recommendation (collaborative filtering) and frequent pattern mining (parallel fp-growth). As of the 0.3 release, an impressive total of 25 machine learning algorithms have been implemented. Apache Mahout achieves scalability by leveraging Apache Hadoop which implements the MapReduce parallel processing paradigm that was first made popular by Google. Latent Dirichlet Allocation is a relatively new algorithm first introduced in 2003 with a suggested use in Topic Modeling (text clustering). Unlike generic clustering algorithms such as k-means, Latent Dirichlet Allocation is able to model document overlap. Latent Dirichlet Allocation is not a hard clustering algorithm and is able to map documents and words to multiple clusters. This feature is a natural fit for documents, which usually discuss multiple topics. The Latent Dirichlet Allocation algorithm simultaneously groups both documents and words into clusters. This is a useful feature as the main words belonging to a cluster and the prominent documents within a cluster are both output by the algorithm. Twitter recently released a feature called Lists that allows you to group people you follow and view the timeline of Tweets for users in a List separately. We will use the Latent Dirichlet Allocation algorithm to cluster people you follow and suggest Lists for Twitter. This will serve as a practical overview of using Apache Mahout for clustering. The following topics of interest are: - What is machine learning? - What is Apache Mahout? - Who is using Apache Mahout? - The MapReduce paradigm - Machine learning with Apache Mahout - Clustering with Apache Mahout - Classification with Apache Mahout - Collaborative Filtering with Apache Mahout - Frequent Pattern Mining with Apache Mahout - Processing Large Datasets with Multiple Cluster Nodes - Building a Twitter List recommendation application with the Latent Dirichlet Allocation algorithm http://2011.linux.conf.au/ - http://www.linux.org.au CC BY-SA - http://creativecommons.org/licenses/by-sa/4.0/legalcode.txt

The Rosette Deduplicate Names operator identifies candidate duplicates from a list of names by assigning “group ids” to groups of matching names. The operator can process lists of up to 10,000 English names and assigns group ids based on a user-specified match threshold. The threshold sets the minimum similarity score required for two names to be considered duplicates. Thresholds can be set by clicking on the operator and entering a value between 0 and 1 in the “Threshold” field. We recommend starting with a .8 threshold, and experimenting with higher or lower values depending upon your use case and results. Given a list of names as input, the output is a list of cluster IDs (integers) for each name—not in any particular order. The output may then be sorted by cluster ID to group together possible duplicate names. https://www.rosette.com/blog/deduplicate-names-rapidminer-rosette/
