text mining use cases
In the case of analyzing movie related data and reviews, considering to predict the financial success of a movie project as an investment (the average movie costs $200M to make) with a high percentage of failure (65% of the movies losing money), the model accuracy is important - hence the models should be built with the latest data and ML techniques. You may find sometimes that you still have hyphens, for example, in some of your tokenized words even after punctuation removal - if that’s the case, you may need to revisit your tokenizer algorithm selection. But if you really do need that few extra percentage points of accuracy and like a challenge, give it a shot! Given enough computing resources, we could even take a deep learning approach to classification, by building out a multi-layer neural network. Is it possible to export workflows as REST services or web-applications? Then, perhaps the interpretation of the output information will be harder because it will include terms and concepts from multiple languages. node for reading large groups of documents - for example if you have folders full of Word or PDF files. would you proceed if the information is not contained in one location only, but distributed across many websites and blog posts? The main reason is that this type of data is very hard to sanitize from private patient information (e.g., required for HIPAA and other governmental regulations). The common practice is to look at the most dominant (or highest weighted) words in the word distribution of a topic and label it with some meaningful description. Also, spend some time to get as familiar as you can with the common pre-processing steps in a text mining process, since you will need to be implementing these over and over again. A text can be considered an entity of... 2 Data Analysis - Market Research / Business Intelligence. Then, perhaps the interpretation of the output information will be harder because it will include terms and concepts from multiple languages. This is one of the easiest nodes to use in the. Some literature was published in languages other than English. This is a classic question: What are the most common use cases requiring text mining? The Tika Parser node, especially, is very flexible and can read a large variety of data files and formats. Essentially, Integrated Deployment captures those portions of the prototype workflow needed for deployment, and these captured portions are automatically replicated and sewn back together to create the deployment workflow. [Rosaria] How stable is a text mining model over time? One great data repository for beginners is probably Kaggle. For example, by checking the movie topics, can I extract their genre? You can also access data stored on web sites using the Webpage Retriever, or via REST API with a GET Request node. Depending on where your data is located, you have several options for bringing them into a KNIME workflow. ”. This free webinar, run by our partner Redfield, will highlight how text mining can significantly benefit your organization and how you can use KNIME Software for your text mining tasks.. To start with, Jan Lindquist from Redfield will take you through the range of insights and knowledge that can be mined from text, using business use cases to highlight this. For example in marketing (online customer interactions), politics (political speeches party alignment), technology (covid-19 app acceptance), research (publication biases), and electronic records (e.g., email, messaging, document repositories), spam filtering, fraud detection, alternative facts detection, and Q&A. In some cases, provided your project meets the criteria, this can perform exceptionally well, but it will definitely take longer to set up and execute than a standard ML approach. For more information, you can check out our ongoing Integrated Deployment post series, along with the corresponding examples on the KNIME Hub. One exception is a new project that I am working on with a medical doctor from NY. What other resources will help me to get started in KNIME? extension because there’s almost no configuration for it - you just apply it to your documents and continue with your processing. Redfield will provide examples from the presentation, which will be available for you to explore further after the webinar. In this way, the prototype workflow and the deployment workflow are always in sync, and you don’t have to manually copy-and-paste nodes from one workflow to the other. Use of text mining to extract knowledge from, - this is similar to the supervised version of sentiment analysis, but the classes are not just limited to degrees of positive and negative feeling. Any forecasted updates for the KNIME Textprocessing Extension? This process can take a lot of information, such as topics that people are talking to, analyze their sentiment about some kind of topic, or to know which words are the most frequent to use at a given time. Maybe the best part is that, if you come up with a really great solution that you think would benefit everyone, you can upload it yourself and share it with the community! A few more questions to conclude. ta is located, you have several options for bringing them into a KNIME workflow. [Scott] Sure! Facebook, Added by Tim Matteson [Dursun] Probably the most popular use cases for text mining nowadays are Sentiment Analysis and Topic Detection. In this use case, companies examine the text that comes from warranty claims, dealer technician lines, report orders, customer relations text, and other potential information using text analytics to extract certain entities or concepts (like the engine or a certain part). node produces both of these outputs as separate tables. [Scott] We’ve recently released the Integrated Deployment feature, which allows you to automatically create production workflows safely from the prototype workflow.
