Stemming cuts words down to their stem (e.g., “running” to “run”), while lemmatization considers the context and converts words to their dictionary form (e.g., “better” to “good”). These techniques are crucial for text analytics.
3. Name Entity Recognition (NER): Identifying and categorizing entities within text, such as names of people, organizations, locations, dates, and more. This is a key part of what is text analytics.
4. Sentiment Analysis: Determining the emotional tone of the text, widely used in analyzing customer reviews, social media posts, and other feedback to gauge public sentiment. This technique is essential in understanding what text analytics is.
5. Keyword Extraction: Identifying the most relevant words and phrases in a text to quickly summarize and understand the main topics within large volumes of data. This is fundamental in what is text analytics.
6. Topic Modeling: Identifying hidden themes or topics within a collection of documents to understand the underlying structure of text data and organize it into meaningful categories. This is a significant aspect of what is text analytics.
7. Text Classification: Categorizing text into predefined classes or labels using machine learning algorithms. This is an important part of what is text analytics.
8. Text Clustering: Grouping similar texts together based on their content to identify natural groupings within text data. This is crucial in what is text analytics.
9. Entity Recognition and Relationship Extraction: Identifying named entities and determining the relationships between them to build knowledge graphs and enhance search engines. This is a key aspect of what is text analytics.
What is Transcription?
Transcription is the process of converting spoken language into written text. This can include converting audio recordings of interviews, meetings, lectures, podcasts, and other forms of spoken communication into text format. Transcription can be done manually by human transcribers or automatically using speech recognition software. The accuracy of transcription depends on various factors, including the quality of the audio, the clarity of speech, background noise, and the proficiency of the transcriber or the capabilities of the transcription software.
Types of Transcription
1. Verbatim Transcription: Capturing every word and sound exactly as spoken, including filler words, pauses, and non-verbal sounds. This is vital for accurate text analytics.
2. Clean Read Transcription: Removing filler words and correcting grammatical errors to produce a more readable text. This aids in what is text analytics.
3. Intelligent Verbatim Transcription: Editing the transcript to remove unnecessary repetitions and irrelevant content while retaining the essence of the conversation. This enhances what is text analytics.
