This document describes a social network based object recommendation system that recommends movies to users by analyzing their Facebook data and movie preferences. It connects to Facebook to fetch a user's liked movies and the IMDB dataset. Movies liked by the user's friends are identified and assigned recommendation scores based on common interests between the user and friend like gender, age and genres. The top scoring movies are recommended and relevance is evaluated based on Facebook suggestions and if the user has watched the recommended movie. Future enhancements could include weighting close friends higher and considering actors and directors.
A key missing piece is assessing the results of SEO efforts, by deriving weighted keywords and phrases from the publicly crawlable website content.
This "reverse engineering" of how search engines view a site is a classic example of web mining, and serves as a useful example to understand better the practical issues involved in real-world web mining.

Interactive Recommender Systems with Netflix and SpotifyChris Johnson
Interactive recommender systems enable the user to steer the received recommendations in the desired direction through explicit interaction with the system. In the larger ecosystem of recommender systems used on a website, it is positioned between a lean-back recommendation experience and an active search for a specific piece of content. Besides this aspect, we will discuss several parts that are especially important for interactive recommender systems, including the following: design of the user interface and its tight integration with the algorithm in the back-end; computational efficiency of the recommender algorithm; as well as choosing the right balance between exploiting the feedback from the user as to provide relevant recommendations, and enabling the user to explore the catalog and steer the recommendations in the desired direction.
In particular, we will explore the field of interactive video and music recommendations and their application at Netflix and Spotify. We outline some of the user-experiences built, and discuss the approaches followed to tackle the various aspects of interactive recommendations. We present our insights from user studies and A/B tests.
The tutorial targets researchers and practitioners in the field of recommender systems, and will give the participants a unique opportunity to learn about the various aspects of interactive recommender systems in the video and music domain.

Movie Recommendation System Using Hybrid Approch.pptxChanduChandran6
In this busy world, entertainment is essential for each of us to refresh our mood and energy. Having fun can restore confidence at work and work with more enthusiasm. To rejuvenate ourselves, we watch our favorite movies. To watch favorable movies online, we can take advantage of more reliable movie recommendation systems, because searching for preferred movies takes more time and cannot be wasted. In this project, a hybrid approach combining content-based filtering and collaborative filtering is presented to improve the quality of a movie recommendation system. Along with that sentiment analysis is done using Bayes Algorithm and Cosine Similarity. The proposed approach shows improvement over pure approaches in the accuracy, quality, and scalability of the movie recommendation system. Three different ones datasets are using in this system. Hybrid approach helps to gain advantages from both approaches and eliminate the disadvantages of both methods.

A recommender system or a recommendation system is a subclass of information filtering systems that seeks to predict the "rating" or "preference" a user would give to an item. (Wiki)
The goal of a Recommender System is to generate meaningful recommendations to a collection of users for items or products that might interest them. (Melville, Sindhwani)

movie information for customers. The recommender system we
implemented is for the movie website.
During the past several decades personnel function has been
transformed from a relatively obscure record keeping staff to central
and top-level management function. important resources. This
project intends to introduce more user friendliness in the various
activities such all the details required for the correct statement
calculation and generation. as record updation, maintenance, and
searching. The searching of record has been made quite simple as all
the details of the customer can be obtained by simply keying in the
identification or account number of that customer. Similarly, record
maintenance and updation can also be accomplished by using the
account number with all the details being automatically generated.
These details are also being promptly automatically updated in the
master file thus keeping the record absolutely up-to-date. The entire
information has maintained in the database or Files and whoever wants to retrieve can't retrieve, only authorization user can retrieve
the necessary information which can be easily be accessible from the
file.
A computer-based recommendation system is designed to handle
all the primary information required to calculate user's emotions.
Separate database is maintained to handle all the details required

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Online Social Network Based Object
Recommendation System
3. Concept & Architecture
Social network based object recommendation
Recommending movies
Social Network: Facebook
Dataset: International Movie Database (IMDB)
Website
Login with
Facebook and
fetch users liked
movies
Server
Spark Web
Framework
Jetty Web Server
MySQL
IMDB Dataset
4. Challenges
Two different sources (Facebook and IMDB)
Sparsity
Even active users may have liked well under 5% percent of the
movies.
Scalability
Billions of users and Millions of movies.
Duplication
As movie ids are different. Have to match the movies with
names.
5. Problems with usual techniques
Nearest Neighbour algorithms require computation that
grows with both the number of users and the number of
movies. With billions of users and millions of movies, a
typical web based recommender system running existing
algorithms will suffer serious scalability problems.
Because of sparsity, a recommender system based on nearest
neighbour algorithm may be unable to make any movie
recommendation for a particular user. As, a result the
accuracy of the recommendations may be poor.
Ever growing data and users set.
6. Our approach
Fetch friends with whom the user has atleast some common
movies. If no common movies, then select all the friends.
Get movies liked by the friends.
For each movie, we get a recommendation score.
Parameters considered while assigning score:
Friends which share some likes with the user
Friends of same gender
Friends of same age group
Movies with same genre
Sort the score and return top “n” movies.
7. Recommendation relevance criteria
As the movies are recommended from a lot of friends, it is
little tricky to figure out if the recommendations are
relevant.
We used two criteria
Movies suggested by Facebook.
Our results are comparable to Facebook movie suggestions. And even
better in some cases.
It is a good recommendation if the user has already watched
that movie.
8. Enhancements
There are some more parameters which can be considered
while ranking a movie
Friend list like “Close Friends”, “Relatives”, etc can be given a
little extra weight.
Actors and directors of the movies can be considered when
ranking.
Similar recommendation systems can be extended to
recommend music, books, etc.
