The systematic application of statistical and logical techniques to describe the data scope, modularize the data structure, condense the data representation, illustrate via images, tables, and graphs, and evaluate statistical inclinations, probability data, to derive meaningful conclusions, is known as Data Analysis. These analytical procedures enable us to induce the underlying inference from data by eliminating the unnecessary chaos created by the rest of it.

Content analysis is a research tool used to determine the presence of certain words, themes, or concepts within some given qualitative data i. Using content analysis, researchers can quantify and analyze the presence, meanings and relationships of such certain words, themes, or concepts. As an example, researchers can evaluate language used within a news article to search for bias or partiality. Researchers can then make inferences about the messages within the texts, the writer s , the audience, and even the culture and time of surrounding the text. Sources of data could be from interviews, open-ended questions, field research notes, conversations, or literally any occurrence of communicative language such as books, essays, discussions, newspaper headlines, speeches, media, historical documents.

Using Facebook for Qualitative Research: A Brief Primer

Companies receive huge amounts of unstructured data in the form of text emails, social media conversations, chats , which can be extremely challenging to analyze. That's where AI solutions like text analysis can help.

Read on to learn how to perform text analysis, with AI tools like MonkeyLearn , why text analysis is important, and explore some of the best text analysis applications and approaches.

Text analysis is a machine learning technique that allows companies to automatically understand text data, such as tweets, emails, support tickets, product reviews, and survey responses. You can us text analysis to extract specific information , like keywords, names, or company information from thousands of emails, or categorize survey responses by sentiment and topic. Firstly, let's dispel the myth that text mining and text analysis are two different processes.

The terms are often used interchangeably to explain the same process of obtaining data through statistical pattern learning. To avoid any confusion here, let's stick to text analysis. So, text analytics vs. Text analysis delivers qualitative results and text analytics delivers quantitative results.

If a machine performs text analysis, it identifies important information within the text itself, but if it performs text analytics, it reveals patterns across thousands of texts, resulting in graphs, reports, tables etc.

Let's say a customer support manager wants to know the outcomes of each support ticket handled by individual team members — was the result positive or negative? By analyzing the text within each ticket, and subsequent exchanges, customer support managers can see team members' individual ticket resolution rates. However, it's likely that the manager also wants to create a graph that visualizes how many tickets were tagged as solved.

In this instance, they'd use text analytics. Basically, the challenge in text analysis is decoding the ambiguity of human language, while in text analytics it's detecting patterns and trends from the results. Text analysis can stretch it's AI wings across a range of texts depending on the results you desire. It can be applied to:. When you put machines to work on organizing and analyzing your text data, the insights and benefits are huge.

Text analysis tools allow businesses to structure vast quantities of information, like emails, chats, social media, support tickets, documents, and so on, in seconds rather than days, so you can redirect extra resources to more important business tasks.

Businesses are inundated with information and customer comments can appear anywhere on the web these days, but it can be difficult to keep an eye on it all. By training text analysis models to detect expressions and sentiments that imply negativity or urgency, businesses can automatically flag tweets, reviews, videos, tickets, and the like, and take action sooner rather than later. Humans make errors.

And the more tedious and time-consuming a task is, the more errors they make. By training text analysis models to your needs and criteria, algorithms are able to analyze, understand, and sort through data much more accurately than humans ever could. There are basic and more advanced text analysis techniques, each used for different purposes. First, learn about the simpler text analysis techniques and examples of when you might use each one.

Word frequency is a text analysis technique that measures the most frequently occurring words or concepts in a given text using the numerical statistic TF-IDF term frequency-inverse document frequency.

You might apply this technique to analyze the words or expressions customers use most frequently in support conversations. For example, if the word 'delivery' appears most often in a set of negative support tickets, this might suggest customers are unhappy with your delivery service. Collocation helps identify words that commonly co-occur. For example, in customer reviews on a hotel booking website, the words 'air' and 'conditioning' are more likely to co-occur rather than appear individually.

Bigrams two adjacent words e. Collocation can be helpful to identify hidden semantic structures and improve the granularity of the insights by counting bigrams and trigrams as one word. Concordance helps identify the context and instances of words or a set of words.

It can also be used to decode the ambiguity of the human language to a certain extent, by looking at how words are used in different contexts, as well as being able to analyze more complex phrases.

Now that we've touched upon the basic techniques of text analysis, we'll introduce you to the more advanced methods: text classification and text extraction. Text classification is the process of assigning predefined tags or categories to unstructured text.

It's considered one of the most useful natural language processing techniques because it's so versatile and can organize, structure, and categorize pretty much any form of text to deliver meaningful data and solve problems.

Natural language processing NLP is a machine learning technique that allows computers to break down and understand text much as a human would. Below, we're going to focus on some of the most common text classification tasks, which include sentiment analysis, topic modeling, language detection, and intent detection.

Customers freely leave their opinions about businesses and products in customer service interactions, on surveys, and all over the internet. Sentiment analysis uses powerful machine learning algorithms to automatically read and classify for opinion polarity positive, negative, neutral and beyond, into the feelings and emotions of the writer, even context and sarcasm.

For example, by using sentiment analysis companies are able to flag complaints or urgent requests, so they can be dealt with immediately — even avert a PR crisis on social media. Sentiment classifiers can assess brand reputation, carry out market research, and help improve products with customer feedback. Try out this pre-trained classifier. Just enter your own text to see how it works:.

For more accuracy, learn how to train your own custom classifier with your own data and criteria in just five steps. Another common example of text classification is topic analysis or topic modeling that automatically organizes text by subject or theme. For example:. If we are using topic categories, like Pricing, Customer Support, and Ease of Use, this product feedback would be classified under Ease of Use.

Text classifiers can also be used to detect the intent of a text. Intent detection or intent classification is often used to automatically understand the reason behind customer feedback. Is it a complaint? Or is a customer writing with the intent to purchase a product?

Machine learning can read chatbot conversations or emails and automatically route them to the proper department or employee. Try out this email intent classifier. Text extraction is another widely used text analysis technique that extracts pieces of data that already exist within any given text.

You can extract things like keywords, prices, company names, and product specifications from news reports, product reviews, and more. You can automatically populate spreadsheets with this data or perform extraction in concert with other text analysis techniques to categorize and extract data at the same time. Keywords are the most used and most relevant terms within a text, words and phrases that summarize the contents of text.

Keyword extraction can be used to index data to be searched and to generate word clouds a visual representation of text data. Try out this pre-trained keyword extractor to see how it works:. Or learn how to train your own custom extractor to your particular needs and criteria.

A named entity recognition NER extractor finds entities, which can be people, companies, or locations and exist within text data. Results are shown labeled with the corresponding entity label, like in this pre-trained person extractor :. It's very common for a word to have more than one meaning, which is why word sense disambiguation is a major challenge of natural language processing.

Take the word 'light' for example. Is the text referring to weight, color, or an electrical appliance? Smart text analysis with word sense disambiguation can differentiate words that have more than one meaning, but only after training models to do so.

Text clusters are able to understand and group vast quantities of unstructured data. Although less accurate than classification algorithms, clustering algorithms are faster to implement, because you don't need to tag examples to train models.

That means these smart algorithms mine information and make predictions without the use of training data, otherwise known as unsupervised machine learning. Google is a great example of how clustering works. When you search for a term on Google, have you ever wondered how it takes just seconds to pull up relevant results?

Google's algorithm breaks down unstructured data from web pages and groups pages into clusters around a set of similar words or n-grams all possible combinations of adjacent words or letters in a text. So, the pages from the cluster that contain a higher count of words or n-grams relevant to the search query will appear first within the results.

To really understand how automated text analysis works, you need to understand the basics of machine learning. Let's start with this definition from Machine Learning by Tom Mitchell :.

In other words, if we want text analysis software to perform desired tasks, we need to teach machine learning algorithms how to analyze, understand and derive meaning from text. But how? The simple answer is by tagging examples of text.

Once a machine has enough examples of tagged text to work with, algorithms are able to start differentiating and making associations between pieces of text, and make predictions by themselves. It's very similar to the way humans learn how to differentiate between topics, objects, and emotions. Let's say we have urgent and low priority issues to deal with. We don't instinctively know the difference between them — we learn gradually by associating urgency with certain expressions.

For example, when we want to identify urgent issues, we'd look out for expressions like 'please help me ASAP! On the other hand, to identify low priority issues, we'd search for more positive expressions like 'thanks for the help! Really appreciate it' or 'the new feature works like a dream'. Let's imagine we work for Slack and want to analyze online reviews to better understand what our customers like and dislike about our platform. We can start out by gathering reviews from sites like Capterra and G2Crowd.

This is the data you generate every day, from emails and chats, to surveys, customer queries, and customer support tickets. Customer Service Software : the software you use to communicate with customers, manage user queries and deal with customer support issues: Zendesk, Freshdesk, and Help Scout are a few examples. CRM : software that keeps track of all the interactions with clients or potential clients.

It can involve different areas, from customer support to sales and marketing. Chat : apps that communicate with the members of your team or your customers, like Slack, Hipchat, Intercom, and Drift.

Email : the king of business communication, emails are still the most popular tool to manage conversations with customers and team members. Surveys : generally used to gather customer service feedback, product feedback, or to conduct market research, like Typeform, Google Forms, and SurveyMonkey.

Many companies use NPS tracking software to collect and analyze feedback from their customers.

Scholars have been increasingly calling for innovative research in the organizational sciences in general, and the information systems IS field in specific, one that breaks from the dominance of gap-spotting and specific methodical confinements. Hence, pushing the boundaries of information systems is needed, and one way to do so is by relying more on data and less on a priori theory.

An Introduction to Text Mining

Content Analysis

As Facebook continues to grow its number of active users, the potential to harness data generated by Facebook users also grows. However, conducting a content analysis of text from Facebook users requires adaptation of research methods used for more traditional sources of qualitative data. Furthermore, best practice guidelines to assist researchers interested in conducting qualitative studies using data derived from Facebook are lacking. The purpose of this primer was to identify opportunities, as well as potential pitfalls, of conducting qualitative research with Facebook users and their activity on Facebook and provide potential options to address each of these issues. We begin with an overview of information obtained from a literature review of 23 studies published between and and our own research experience to summarize current approaches to conducting qualitative health research using data obtained from Facebook users. We then identify potential strategies to address limitations related to current approaches and propose 5 key considerations for the collection, organization, and analysis of text data from Facebook.

Text mining also known as text analysis , is the process of transforming unstructured text into structured data for easy analysis. Text mining uses natural language processing NLP , allowing machines to understand the human language and process it automatically. For businesses, the large amount of data generated every day represents both an opportunity and a challenge. Think about all the potential ideas that you could get from analyzing emails, product reviews, social media posts, customer feedback, support tickets, etc. This guide will go through the basics of text mining, explain its different methods and techniques, and make it simple to understand how it works. You will also learn about the main applications of text mining and how companies can use it to automate many of their processes:. Text mining is an automatic process that uses natural language processing to extract valuable insights from unstructured text.

While data analysis in qualitative research can include statistical procedures, many times analysis becomes an ongoing iterative process where data is continuously collected and analyzed almost simultaneously. Indeed, researchers generally analyze for patterns in observations through the entire data collection phase Savenye, Robinson, The form of the analysis is determined by the specific qualitative approach taken field study, ethnography content analysis, oral history, biography, unobtrusive research and the form of the data field notes, documents, audiotape, videotape. An essential component of ensuring data integrity is the accurate and appropriate analysis of research findings. Improper statistical analyses distort scientific findings, mislead casual readers Shepard, , and may negatively influence the public perception of research. Integrity issues are just as relevant to analysis of non-statistical data as well.

Gabe Ignatow and Rada Mihalcea's An Introduction to Text Mining: Research Design, Data Collection, and Analysis provides a foundation for.

Повсюду в старинных домах отворялись ворота, и люди целыми семьями выходили на улицы. Подобно крови, бегущей по жилам старого квартала Санта-Крус, они устремлялись к сердцу народа, его истории, к своему Богу, своему собору и алтарю. Где-то в уголке сознания Беккера звонили колокола. Я не умер.

Она побледнела и прошептала: - О Боже… Стратмор утвердительно кивнул, зная, что она догадалась. - Он целый год хвастался, что разрабатывает алгоритм, непробиваемый для грубой силы. - Н-но… - Сьюзан запнулась, но тут же продолжила: - Я была уверена, что он блефует.

Пять секунд. Шесть секунд. - Утечка информации. - Никаких изменений. Внезапно Мидж судорожно указала на экран.

 Не имеет значения.

Хейл подтянул ноги и немного приподнялся на корточках, желая переменить позу. Он открыл рот, чтобы что-то сказать, но сделать этого не успел. Когда Хейл перестал на нее давить, Сьюзан почувствовала, что ее онемевшие ноги ожили. Еще толком не отдавая себе отчета в своих действиях и повинуясь инстинкту, она резким движением согнула ноги и со всей силы ударила Хейла коленом в промежность, ощутив, как ее коленные чашечки впились в его мягкие незащищенные ткани. Хейл взвыл от боли, и все его тело сразу же обмякло.

Техники сновали по комнате. Что-то подсказывало Сьюзан, что они близки к разгадке. - Мы можем это сделать! - сказала она, стараясь взять ситуацию под контроль.

Слишком уж удобная версия. Стратмор пожал плечами. - Слабое сердце… да к тому же еще испанская жара. Не забывай и о сильнейшем стрессе, связанном с попыткой шантажировать наше агентство… Сьюзан замолчала. Какими бы ни были обстоятельства, она почувствовала боль от потери талантливого коллеги-криптографа.
