Sentiment analysis helps you spot new trends, track sentiment changes, and tackle PR issues. By using sentiment analysis and identifying specific keywords, you can track changes in customer opinion and identify the root cause of the problem. Artificial intelligence is the field of data science that teaches computers to think like humans. Machine learning is a technique within artificial intelligence that uses specific methods to teach or train computers. Deep learning is a highly specialized machine learning method that uses neural networks or software structures that mimic the human brain. Deep learning technology powers text analysis software so these networks can read text in a similar way to the human brain.

LangTec’s DocumentCreator addresses this challenge and permits to create large volumes of training data with wide structural variance based on just a few input samples. With DocumentCreator in place your machine learning algorithms can be trained, evaluated and tuned robustly prior to deployment into production even when only very little actual data is at hand. You can find external data in sources such as social media posts, online reviews, news articles, and online forums.

Text Analytics or text mining utilises a plethora of methods from computational linguistics and artificial intelligence in order to convert unstructured textual data into structured information. Specifically, patterns and structures are extracted from input texts based on lexical properties, syntactic structures, statistical observations and machine learning with the overall aim of gaining deep semantic insights from textual input. Depending on project objective and context LangTec chooses from a wide range of possible machine learning methods. In the deep-learning domain we increasingly avail of pretrained language models. For our research-driven projects we also use transfer learning and model distillation.

The primary role of Resource Description Framework (RDF) is to store meaning with data and represent it in a structured way that is meaningful to computers. SciBite has developed a method that combines Semantic Analytics and Machine Learning to unlock the potential of biomedical literature and successfully predict disease Chat PG relationships without any prior knowledge of the diseases, based on the strength of indirect evidence. Health forums, such as PatientsLikeMe, provide a wealth of valuable information, but many current computational approaches struggle to deal with the inherent ambiguity and informal language used within them.

PII redaction automatically detects and removes personally identifiable information (PII) such as names, addresses, or account numbers from a document. PII redaction helps protect privacy and comply with local laws and regulations. Here we describe how the combination of Hadoop and SciBite brings significant value to large-scale processing projects.

Text Analytics highlights the recurring themes and up-and-coming topics that are driving

positive and negative customer sentiment. It surfaces these insights through user-friendly

trend charts, word cloud reports and stats tables. Once your texts have been uploaded, you can begin to add semantic tags to the texts and analyse them using the tools included in the notebook. You can display the semantic tags, the pos-tagging and the MWE indicator for each token in a particular text, and compared them side by side with those from another text.

Text analytics helps you determine if there’s a particular trend or pattern from the results of analyzing thousands of pieces of feedback. Meanwhile, you can use text analysis to determine whether a customer’s feedback is positive or negative. Visualization is about turning the text analysis results into an easily understandable format.

Get Analysis You Can Understand

You are able to run it in the cloud and any dependencies with other packages will be installed for you automatically. In addition to the USAS tags, you will also see the lemmas and Part-of-Speech (POS) tags in the text. For English, the tagger also identifies and tags Multi Word Expressions (MWE), i.e., expressions formed by two or more words that behave like a unit such as ‘South Australia’.

Our expectation into our own work is that the resulting solutions achieve a quality and efficiency level that substantially exceeds human-level performance. Only if the resulting solution really outperforms humans notably do we deem the label ‘artificial intelligence’ appropriate. And even if artificial intelligence and machine learning are extremely closely interwoven these days, does our understanding of the term ‘AI’ extend far beyond just machine learning. Text analysis software works on the principles of deep learning and natural language processing.

To implement text analysis, you need to follow a systematic process that goes through four stages. Artificial Intelligence (AI) has been touted as a way to revolutionise the entire pharmaceutical value chain. Despite such promises, tangible evidence of how AI is actually helping research has been elusive. Some academic research groups that have active project in this area include Kno.e.sis Center at Wright State University among others. Instead of classic NLP technologies, Dandelion API leverages its underlying Knowledge Graph, without relying on traditional NLP pipelines.

Both terms refer to the same process of gaining valuable insights from sources such as email, survey responses, and social media feeds. Through semantic enrichment, SciBite enables unstructured documents to be converted to RDF, providing the high quality, contextualised data needed for subsequent discovery and analytics to be effective. SciBite uses semantic analytics to transform the free text within patient forums into unambiguous, machine-readable data. This enables pharmaceutical companies to unlock the value of patient-reported data and make faster, more informed decisions. Classification is the process of assigning tags to the text data that are based on rules or machine learning-based systems.

Today, the automated generation of journalistic content from structured data is almost commodity. Automated text generation draws on methods from computational linguistics and artificial intelligence to create human-readably copy text informed by structured data. LangTec’s solution TextWriter permits to optimise generated texts with regards to a number of parameters such as text uniqueness, SEO relevance, readability, text length, target group or output channel. Sentiment analysis or opinion mining uses text analysis methods to understand the opinion conveyed in a piece of text. You can use sentiment analysis of reviews, blogs, forums, and other online media to determine if your customers are happy with their purchases.

For example, you can use text extraction to monitor brand mentions on social media. Manually tracking every occurrence of your brand on social media is impossible. Most pharmaceutical companies will have, at some point, deployed an Electronic Laboratory Notebook (ELN) with the goal of centralising R&D semantic textanalytics data. ELNs have become an important source of both key experimental results and the development history of new methods and processes. Hadoop systems can hold billions of data objects but suffer from the common problem that such objects can be hard or organise due to a lack of descriptive meta-data.

With our team of computational linguists, data scientists and software engineers, we’ve been operating successfully in the market place since 2011. For a comprehensive list of our clients as well as project descriptions, please click here. Natural language processing (NLP) is a branch of artificial intelligence that gives computers the ability to automatically derive meaning from natural, human-created text. It uses linguistic models and statistics to train the deep learning technology to process and analyze text data, including handwritten text images. NLP methods such as optical character recognition (OCR) convert text images into text documents by finding and understanding the words in the images.

The application of semantic analysis methods generally streamlines organizational processes of any knowledge management system. Academic libraries often use a domain-specific application to create a more efficient organizational system. By classifying scientific publications using semantics and Wikipedia, researchers are helping people find resources faster. Search engines like Semantic Scholar provide organized access to millions of articles.

Lastly, you can save the tagged texts onto a comma separated values (csv) file containing the tagged texts, or a zip of pseudo-xml (.txt) tagged text files and download it to your local computer. Stop words are words that offer little or no semantic context to a sentence, such as and, or, and for. Depending on the use case, the software might remove them from the structured text.

In the early days of semantic analytics, obtaining a large enough reliable knowledge bases was difficult. In 2006, Strube & Ponzetto demonstrated that Wikipedia could be used in semantic analytic calculations.[2] The usage of a large knowledge base like Wikipedia allows for an increase in both the accuracy and applicability of semantic analytics. This tagger will allow you to tag text data in a text file (or a number of text files). Alternatively, you can also tag text inside a text column inside your excel spreadsheet. Text analytics is the quantitative data that you can obtain by analyzing patterns in multiple samples of text.

However, evidence of disease similarity is often hidden within unstructured biomedical literature and often not presented as direct evidence, necessitating a time consuming and costly review process to identify relevant linkages. Such linkages are particularly challenging to find for rare diseases for which the amount of existing research to draw from is still at a relatively low volume. Our semantic analysis

engine automatically parses people’s names out of reviews so you can see how they are impacting

your customers’ experience. For example, you can analyze support tickets and knowledge articles to detect and redact PII before you index the documents in the search solution.

Real-world evidence reported by patients themselves is an under-utilised resource for pharmaceutical companies striving to remain competitive and maintain awareness of the effects of their drugs. Create reports customized to any category or set of keywords that you are keen on keeping tabs

on. Text Analytics will analyze this information on an ongoing basis and help you determine

how new products, offerings or services are being received by customers.

Then you can run different analysis methods on invoices to gain financial insights or on customer agreements to gain customer insights. For example, a favorable review often contains words like good, fast, and great. Data scientists train the text analysis software to look for such specific terms and categorize the reviews as positive or negative. This way, the customer support team can easily monitor customer sentiments from the reviews.

SciBite can improve the discoverability of this vast resource by unlocking the knowledge held in unstructured text to power next-generation analytics and insight. With the rise in machine learning and artificial intelligence approaches to big data, systems that can integrate into the complex ecosystem typically found within large enterprises are increasingly important. Data-driven drug development promises to enable pharmaceutical companies to derive deeper insights and make faster, more informed decisions. A fundamental step to achieving this nirvana is important to be able to make sense of the information available and to make connections between disparate, heterogeneous data sources.

Our expertise in REST, Spring, and Java was vital, as our client needed to develop a prototype that was capable of running complex meaning-based filtering, topic detection, and semantic search over huge volumes of unstructured text in real time. Inspired by the latest findings on how the human brain processes language, this Austria-based startup worked out a fundamentally new approach to mining large volumes of texts to create the first language-agnostic semantic engine. Fueled with hierarchical temporal memory (HTM) algorithms, this text mining software generates semantic fingerprints from any unstructured textual information, promising virtually unlimited text mining use cases and a massive market opportunity. This semantic enrichment opens up new possibilities for you to mine data more effectively, derive valuable insights and ensure you never miss something relevant. For example, you can use topic modeling methods to read through your scanned document archive and classify documents into invoices, legal documents, and customer agreements.

Given the subjective nature of the field, different methods used in semantic analytics depend on the domain of application. With the advent of deep learning new machine learning techniques have become available over the past 10 years whose increase in performance comes at the cost of a substantially increased need for annotated training data. You can foun additiona information about ai customer service and artificial intelligence and NLP. Regrettably, in actual practice consistently and comprehensively annotated training data is not always available, be it for reasons of data protection, copyright or simply the insufficient scope or quality of costly manual annotation.

This makes it faster, more scalable, easier to customize and natively language independent. Extracted entities are linked with the huge amount of additional data available in our internal Knowledge Graph, which contains both open and proprietary high-quality data. Thanks to its revolutionary technology, Dandelion API works well even on short and malformed texts in English, French, German, Italian, Spanish and Portuguese.

You might need to use web scraping tools or integrate with third-party solutions to extract external data. Topic modeling methods identify and group related keywords that occur in an unstructured text into a topic or theme. These methods can read multiple text documents and sort them into themes based on the frequency of various words in the document. The term ‘Artificial Intelligence’ denotes a broad category subsuming all of our project and product-related activities here at LangTec.

Text mining is the process of obtaining qualitative insights by analyzing unstructured text. Text analysis is the core part of the process, in which text analysis software processes the text by using different methods. However, most pharmaceutical companies are unable to realise the true value of the data stored in their ELN. Much of the information stored within it is captured as qualitative free text or as attachments, with the ability to mine it limited to rudimentary text and keyword searches. By accurately tagging all relevant concepts within a document, SciBite enables you to rapidly identify the most relevant terms and concepts and cut through the background ‘noise’ to get to the real essence of the article.

Text analysis leads to efficient management, categorization, and searches of documents. This includes automating patient record management, monitoring brand mentions, and detecting insurance fraud. For example, LexisNexis Legal & Professional uses text extraction to identify specific records among 200 million documents.

The visualized results help you identify patterns and trends and build action plans. For example, suppose you’re getting a spike in product returns, but you have trouble finding the causes. With visualization, you look for words such as defects, wrong size, or not a good fit in the feedback and tabulate them into a chart. Extraction involves identifying the presence of specific keywords in the text and associating them with tags. The software uses methods such as regular expressions and conditional random fields (CRFs) to do this.

However, despite significant advances in the technology, many computational approaches struggle to accurately tag and disambiguate scientific terms, let alone deal with the complexity and variability of unstructured scientific language. All rights are reserved, including those for text and data mining, AI training, and similar technologies. Semantic analytics, also termed semantic relatedness, is the use of ontologies to analyze content in web resources. This field of research combines text analytics and Semantic Web technologies like RDF. Easy to integrate into existing systems via a powerful REST API, the engine runs on a scalable infrastructure that can process millions of documents per-day. We also offer on-premise integration for enterprise customers with special data protection issues.

We also presented a prototype of text analytics NLP algorithms integrated into KNIME workflows using Java snippet nodes. This is a configurable pipeline that takes unstructured scientific, academic, and educational texts as inputs and returns structured data as the output. Users can specify preprocessing settings and analyses to be run on an arbitrary number of topics. The output of NLP text analytics can then be visualized graphically on the resulting similarity index. Our client partnered with us to scale up their development team and bring to life their innovative semantic engine for text mining.
