Learning objectives
  • Characterize the phenomena of text analytics and Natural Language Processing
  • Summarize different fundamental concepts, techniques and methods of Natural Language Processing
  • Analyze and apply different text analytics techniques for big/business datasets in organizational contexts
  • Understand the linkages between business intelligence and text analytics and the potential benefits for organizations
  • Summarize the application areas, trends, and challenges in text analysis
  • Exhibit deeper knowledge and understanding of the topics as part of the project and the report should reflect on critical awareness of the methodological choices with written skills to accepted academic standards
Course prerequisites
This course requires a fundamental understanding of programming in Python language as achieved in, or comparable to "Foundations of Data Science: Programming and Linear Algebra" at 1st semester CM (data science).
Prerequisites for registering for the exam (activities during the teaching period)
Number of compulsory activities which must be approved (see s. 13 of the Programme Regulations): 2
Compulsory home assignments
Each assignment is 1-3 pages in group of 1-4 students.
The students have to get 2 out of 3 assignments approved in order to go to the exam.

There will not be any extra attempts provided to the students before the ordinary exam.
If a student cannot hand in due to documented illness, or if a student does not get the activity approved in spite of making a real attempt, then the student will be given one extra attempt before the re-exam. Before the re-exam, there will be one home assignment (max. 10 pages) which will cover 2 mandatory assignments.
Examination

Grading scale 7-point grading scale
Examiner(s) Internal examiner and external examiner
Exam period Summer
Make-up exam/re-exam
Same examination form as the ordinary exam
Students can submit the same project or they can choose to submit a revised project.
Course content, structure and pedagogical approach

The course provides knowledge of various concepts, techniques and methods related to text analytics. Furthermore, it introduces

 

  • Basics of Natural Language Processing (NLP) such as POS-tagging, Entity recognition
  • Language Modeling using N-grams
  • Text classification using supervised machine learning approaches
  • Unsupervised methods for NLP and latent models.
  • Word-embeddings and Word Vectors
  • Neural Networks for NLP and Neural Language Models
  • Information Retrieval

  • Relation Extraction, Question Answering, Dialog systems and Chatbots

  • Web Crawling and Link Analysis

 

Furthermore, the course provides the students with practical hands-on experience on text analytics using open source machine learning libraries such as scikit-learn, Natural Language Toolkit (NLTK) in Python programming language. After completing the course the students will be able to apply and use various NLP techniques such as sentiment/emotion analysis opinion mining etc. on textual documents/ text corpora.
Description of the teaching methods
The course consists of lectures, exercises, and assignments. Each lecture is followed by an exercise session, and there will be a teaching assistant providing technical support for assignments and course projects.

The presented theories, concepts and methods should be applied in practice and exercise sessions. The students work in the entire semester on a mini project displaying the understanding of the concepts presented in the lectures and exercises. CBS Learn is used for sharing documents, slides, exercises etc. as well as for interactive lessons if applicable.
Feedback during the teaching period
In this course, feedback to the students will be provided in the following ways.

1) During the hands-on exercises following each lecture, the students will receive help and feedback in solving the practical hands-on exercises from the teacher and the instructors.

2) At the end of each exercise session, we will go through the solutions to the exercises and discuss various techniques and alternative methods to solve the exercises and also clarify any questions from the students.

3) Feedback on the mandatory assignments will be provided to students as part of the grading for the mandatory assignments. Since the mandatory assignments are at the group level, the students will receive collective feedback on their group submission.

Student workload
Lectures 24 hours
Exercises 24 hours
Prepare to class 48 hours
Project work & report 100 hours
Exam and prepare 10 hours
Total 206 hours
Expected literature

The literature can be changed before the semester starts. Students are advised to find the final literature on Canvas before they buy the books.
