This document describes a project to filter tweets related to entities. The team used supervised machine learning with features extracted from tweets, entity homepages, and wikipedia pages to train an SVM model to classify tweets as related or unrelated to entities. The preprocessing removed user mentions, URLs, punctuation, and stop words before extracting features. Testing the model on 61 entities achieved an overall accuracy of 80% for classifying tweets, with accuracy for individual entities ranging from 96% to 40%.

Building a Semantic Web of Comic Book Metadata: User Application Profiles for Publishing Linked Data in HTML/RDFa
Kent State University - November 11, 2014
The objective of this research was to present a case study for developing a domain ontology, and explore methodologies for improving the usability and potential usage of that vocabulary through the development of interoperable metadata application profiles designed for specific groups of users within a community. This objective was realized by the development of a metadata vocabulary for comic books and comic book collections, and a series of metadata application profiles designed for publishing Linked Data in the content of existing information systems using HTML/RDFa. Semantic Web standards and technologies represent an opportunity for connecting data about comic books and graphic novels in LOD datasets with detailed, community-created data on the open Web. Recognizing the potential for an open exchange of data about comic books and graphic novels, a case study was designed to gain a comprehensive understanding of the domain and develop an effective data model. The initial phase of the study involved a review of information and reference resources, acquisition of example materials, and practical experience gained indexing comics in a collaborative Web database. A metamodel for comics was then developed and realized as an XML schema, with those elements mapped as properties to classes in an OWL ontology. In order to align the ontology with the wider Web environment and validate the model, the final phase of the case study explored external sources through a review of existing information systems and an analysis of their content. Results were then summarized as skeleton, data-driven user persona documents, which were used to guide the design of a series of metadata application profiles representing the functional requirements identified. The profiles build upon a core schema and incorporate elements from other Web vocabularies as necessary, focusing on publishing Linked Data in existing information systems using HTML/RDFa. Examples were explored and validated for their ability to link to LOD resources and produce meaningful, valid RDF data consistent with the Ontology. The final result is a flexible and extensible, semantic model for comics. The Comic Book Ontology (CBO) as an RDFS/OWL vocabulary is compatible with a variety of other systems, including next-generation library catalogs, where it can potentially be used in a collaborative exchange of data to describe relationships between comics material and content not previously available. This study demonstrates how an ontology can be applied to existing collaborative projects, database, content, or research to enhance the visibility, reference, and utilization of those endeavors through their publication as Linked Data.

166 - ISBSG variables most frequently used for software effort estimation: A ...ESEM 2014
Background: The International Software Benchmarking Standards Group (ISBSG) dataset makes it possible to estimate a project’s size, effort, duration, and cost.
Aim: The aim was to analyze the ISBSG variables that have been used by researchers for software effort estimation from 2000, when the first papers were published, until the end of 2013.
Method: A systematic mapping review was applied to over 167 papers obtained after the filtering process. From these, it was found that 133 papers produce effort estimation and only 107 list the independent variables used in the effort estimation models.
Results: Seventy-one out of 118 ISBSG variables have been used at least once. There is a group of 20 variables that appear in more than 50% of the papers and include Functional Size (62%), Development Type (58%), Language Type (53%), and Development Platform (52%) following ISBSG recommendations. Sizing and Size attributes altogether represent the most relevant group along with Project attributes that includes 24 technical features of the project and the development platform. All in all, variables that have more missing values are used less frequently.
Conclusions: This work presents a snapshot of the existing usage of ISBSG variables in software development estimation. Moreover, some insights are provided to guide future studies.

Scalable Automatic Machine Learning in H2OSri Ambati
Abstract:
In recent years, the demand for machine learning experts has outpaced the supply, despite the surge of people entering the field. To address this gap, there have been big strides in the development of user-friendly machine learning software that can be used by non-experts. Although H2O and other tools have made it easier for practitioners to train and deploy machine learning models at scale, there is still a fair bit of knowledge and background in data science that is required to produce high-performing machine learning models. Deep Neural Networks in particular, are notoriously difficult for a non-expert to tune properly.
In this presentation, we provide an overview of the the field of "Automatic Machine Learning" and introduce the new AutoML functionality in H2O. H2O's AutoML provides an easy-to-use interface which automates the process of training a large, comprehensive selection of candidate models and a stacked ensemble model which, in most cases, will be the top performing model in the AutoML Leaderboard.
H2O AutoML is available in all the H2O interfaces including the h2o R package, Python module and the Flow web GUI. We will also provide simple code examples to get you started using AutoML.

Test automation framework designs by Martin Lienhard. In this slide Martin describes the phases of designing a test automation framework, and why we should move far, far away from record & playback test scripts. Data-driven and parameterized tests from external files, DBs, etc. External UI maps of locators. Using multiple test tools (Selenium/WebDriver being the favorite, of course). Testing across multiple environments on parallel deployment paths with different application versions.

Consolidating MLOps at One of Europe’s Biggest AirportsDatabricks
At Schiphol airport we run a lot of mission critical machine learning models in production, ranging from models that predict passenger flow to computer vision models that analyze what is happening around the aircraft. Especially now in times of Covid it is paramount for us to be able to quickly iterate on these models by implementing new features, retraining them to match the new dynamics and above all to monitor them actively to see if they still fit the current state of affairs.
To achieve those needs we rely on MLFlow but have also integrated that with many of our other systems. So have we written Airflow operators for MLFlow to ease the retraining of our models, have we integrated MLFlow deeply with our CI pipelines and have we integrated it with our model monitoring tooling.
In this talk we will take you through the way we rely on MLFlow and how that enables us to release (sometimes) multiple versions of a model per week in a controlled fashion. With this set-up we are achieving the same benefits and speed as you have with a traditional software CI pipeline.

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.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

1. FILTERING TWEETS RELATED TO AN ENTITY
TEAM: GROUP 8, PROJECT 19
• MALLIKARJUN B R(201307681)
• APRATIM UTKARSH(201305516)
• RISHABH LADHA(201101014)
• KARTIK DUBEY(201001117)
2. Introduction
• One of the major problem in monitoring the online reputation of companies, is to
decide about the entity information.
• Given a tweet, need to decide whether it belongs to a particular entity or not.
• Problem is particularly hard in microblogging services such as Twitter.
3. APPROACH
• Supervised Machine learning is used to decide if the entity belongs to an entity or
not.
• Dataset from RepLab, home page and wikipedia page of the entity is being used.
• It involves pre-processing of the above data, extracting features from the data to
train using SVM.
• Test data also goes through same procedure, the output is predicted using the
weight vector obtained from the trained model.
6. Pre-Processing
• Extract user mentions and URLs
• Convert hashtags to words by removing the hash symbol
• Remove all punctuation
• Convert text to lower case
• Remove accents and convert non-ASCII characters to their ASCII equivalents
• Remove stop-words based on the list of stop words for English.
7. Features
• Similarity w.r.t related tweets
• Similarity w.r.t unrelated tweets
• Keyword similarity using Word-Net database
• Web similarity
9. Evaluation and Results
• Corpus consists of tweets and a list of 61 entities.
• Trained over each entity separately using libsvm.
• Using the test data for each entity, we calculated the accuracy for entire dataset
• Accuracy of entity varies from 96% to 40%. Overall accuracy is 80%.
10. Conclusion
• In this paper we tackled the problem of company name disambiguation in Twitter
• The main goal of this task was to classify tweets as relevant or not to a given
target entity
• We have explored several types of features, namely similarity between keywords,
TF-IDF of n-grams and we have also explored external resources such as Freebase
and Wikipedia.
• Results show that it is possible to achieve an Accuracy over 0.90.
