Natural Language Inference for Humans
0 likes285 views
The document discusses natural language inference (NLI) in the context of computer science and highlights the contributions of Valeria de Paiva, emphasizing her work in symbolic and distributional approaches. It addresses the challenges in creating accurate and reliable datasets for NLI, particularly the SICK dataset, and the need for better annotation guidelines. Additionally, it touches on the status of women in computer science, detailing efforts to promote inclusivity and increase the representation of women in the field.

Women in Computer Science
Are we there yet?
Manning: Computational Linguistics and Deep Learning, 2015
”NLP is kind of like a rabbit in the headlights of the Deep
Learning machine, waiting to be flattened.”
Hinton 2015: ”I will be disappointed if in five years’ time we do
not have something that can watch a YouTube video and tell a
story about what happened.”

I work in industry in Silicon Valley, have done so for the last 20 years, applying the purest of pure mathematics, in surprising ways. Valeria de Paiva Women+@DCS

- 8. 8/23 Introduction NL Inference Women in Computer Science Natural Language Inference: why? In May 2016 Google announced Parsey McParseface, the world’s most accurate parser1: 94% accuracy In 2014 Marelli et al launched the SICK corpus at SemEval 2014: an easy (no named entities, no temporal phenomena, limited vocabulary, etc..), linguist curated corpus to test compositional knowledge Can we use SyntaxNet to process SICK with off-the-shelf tools such as WordNet and SUMO? It’s complicated! Five papers and counting! 1 ai.googleblog.com/2016/0/announcing-syntaxnet-worlds-most. html Valeria de Paiva Women+@DCS

- 10. 10/23 Introduction NL Inference Women in Computer Science NLI for Humans Easier to detect inference than to decide on “good”semantic representations Data-driven NLU need large, diverse, high-quality corpora annotated to learn inference relations: entails, contradicts, neutral Can we trust the corpora we have? Are they really learning logical inferences? Are the findings on the big corpora available SNLI, MNLI, SciTail, etc transferable and generalizable? (Plenty of recent work showing no, systems learn biases of the corpora, cannot be redeployed) Valeria de Paiva Women+@DCS

- 12. 12/23 Introduction NL Inference Women in Computer Science NLI for SICK Are the annotations in SICK logical? Can we trust them? Several problems: lack of guidelines on co-reference, how to annotate contradictions, ungrammatical and non-sensical sentences, noisy data, etc.. This meant contradictions in SICK are not symmetric and they need to be Contradictions require alignment between entities and events, which need to be ”close enough” how to decide when things are close enough? Can we do simpler case where sentences are ”one-word-apart”using WordNet? More guidelines necessary for SICK annotation? Valeria de Paiva Women+@DCS

- 15. 15/23 Introduction NL Inference Women in Computer Science Conclusions so far Working for division of semantic labor between symbolic/structural and distributional approaches Have fledgling proposal GKR with strict separation of conceptual and contextual structures Also concrete proposal for injecting distributionality in GKR: promising results (COLING submission) Further Work: Still working to produce a ‘correct’ SICK Working on annotations and theorem provers test GKR with further datasets, further distributional architectures Valeria de Paiva Women+@DCS

- 17. 17/23 Introduction NL Inference Women in Computer Science Women in Computer Science I grew up believing most of the gender wars had been fought by our grandmothers, suffragettes or not. that the law allowed me to get into colleges and work places. that I could always apply for scholarships and grants. I had plenty of women teachers. I thought my job was to work hard and show people I could do the job as well as any man I knew the numbers were bad both in Computing and in Maths, but I thought they’re bad as usual, not particularly bad. That time would be on our side, that things were going to get more equal as time went by Valeria de Paiva Women+@DCS
