Networks are ubiquitous in many real-world applications (e.g., social networks encoding trust/distrust relationships, correlation networks arising from time series data). While many networks are signed or directed, or both, there is a lack of unified software packages on graph neural networks (GNNs) specially designed for signed and directed networks. In this paper, we present PyTorch Geometric Signed Directed (PyGSD), a software package which fills this gap. Along the way, we evaluate the implemented methods with experiments with a view to providing insights into which method to choose for a given task. The deep learning framework consists of easy-to-use GNN models, synthetic and real-world data, as well as task-specific evaluation metrics and loss functions for signed and directed networks. As an extension library for PyG, our proposed software is maintained with open-source releases, detailed documentation, continuous integration, unit tests and code coverage checks.

Computers aren't going to replace creative pros -- but machine learning and artificial intelligence can be powerful tools in the storytelling process. The 60-second spot was directed by Oscar-winner Kevin Macdonald, working from a script that was developed by IBM's Watson AI system. To produce the spot for the Lexus ES executive sedan launching in Europe, the automaker enlisted its creative agency, The&Partnership London, along with technical partner Visual Voice. The agencies collaborated with the IBM Watson team to use AI to analyze 15 years' worth of footage, text and audio for car and luxury brand campaigns that have won Cannes Lions awards for creativity, as well as a range of other external data. Watson identified elements common to award-worthy commercials that were "both emotionally intelligent and entertaining," according to IBM.

Horror and Halloween-themed films led the weekend box office before the Oct. 31 holiday with Lionsgate's latest, "Jigsaw," coming out on top while the George Clooney-helmed "Suburbicon" proved to be a massive disappointment. "Jigsaw," the eighth installment in the popular "Saw" franchise, scared up an estimated $16.2 million in the U.S. and Canada, according to figures from measurement firm ComScore. It tops the chart during a relatively slow week and brings to end a sluggish October, as this year's box office continues to trail that of 2016. Directed by Michael and Peter Spierig, the R-rated "Jigsaw" follows, in reviewer Noel Murray's words, "bad folks stuck in an elaborate torture chamber" and earned an average B-rating from audience polling service CinemaScore and a 39% "rotten" rating on review aggregation site Rotten Tomatoes. "Jigsaw" comes seven years after "Saw VII: The Final Chapter," once intended to wrap the franchise, and 13 years after the first "Saw" film.

It's been a great season for horror, with Blumhouse's "Happy Death Day" becoming the latest horror film to top the domestic box office in its opening weekend. The $5-million film, a bloody riff on the classic "Groundhog Day" concept, brought in an estimated $26.5 million in the U.S. and Canada, according to figures from measurement firm ComScore, above the $15 million to $20 million analysts projected. "We are absolutely thrilled with the opening," said Universal's Executive Vice President of Domestic Distribution Jim Orr. "Happy Death Day" marks Blumhouse's ninth film to open at No. 1 and its third to debut at No. 1 this year alone, following "Split" and "Get Out." The latest from producer Jason Blum and Universal Pictures, the film, about a woman who relives the day of her murder until she learns her killer's identity, earned a B rating on CinemaScore and a 64% "fresh" rating on Rotten Tomatoes.

Close to 350 actors took their grievances to Electronic Arts in Playa Vista on Monday, marching and chanting for more pay and better working conditions for performers who do voice-over and motion-capture work on blockbuster video game titles. The picket line was the latest signal from SAG-AFTRA that it is preparing for a long fight with several prominent game companies, as both sides have failed to agree on the union's demand for residual-like payments that are commonplace in film and TV but not in the gaming industry. SAG-AFTRA also wants employers to reveal the titles of games when hiring actors, but companies including Activision Blizzard, Electronic Arts and Take Two Interactive are arguing that level of transparency is impossible and could put them at a competitive disadvantage. On Monday, the video game companies hit back, accusing SAG-AFTRA negotiators of failing to communicate the most recent proposal to its members before officially calling the strike Friday. "If I was a performer, I would want the opportunity to say yes or no," said Scott Witlin, a lawyer at Barnes & Thornburg and chief negotiator for the gaming companies, during a news conference Monday afternoon.

This paper builds upon several recent research efforts that have explored the nature and qualities of questions asked on these social Q&A sites by offering a focused examination of answers posted to three of the most popular Q&A sites. Specifically, this paper examines sets of answers responding to specific types of questions and explores the degree to which question types are predictive of answer quantity and answer quality. Blending qualitative and quantitative methods, the paper builds upon rich coding of a representative sets of real questions — drawn from Answerbag, (Ask) MetaFilter, and Yahoo! Answers — in order to better understand whether the explicit and implicit theories and predictions drawn from coding of these questions were borne out in the corresponding answer sets found on these sites. Quantitative findings include data underscoring the general overall success of social Q&A sites in producing answers that can satisfy the needs of those who pose questions. Additionally, this paper presents a predictive model that can anticipate the archival value of answers based on the category and qualities of questions asked. Qualitative findings include an analysis of the variation in responses to questions that are primarily seeking objective, grounded information relative to those seeking subjective opinions.
