This document discusses modelling goals and desires in first-person narratives. The key points are:
1) The researchers created a new corpus called DesireDB containing 3,500 first-person narratives annotated with fulfillment statuses of expressed desires.
2) They aim to identify goal and desire expressions, infer their fulfillment from context, and classify fulfillment status using features like discourse markers and sentiment flow.
3) Classification experiments use LSTM embeddings and RNN models on a subset of DesireDB, exploring the impact of different feature sets and context. Prior context improves results more than post context. Identifying unfulfillment is harder.
Here are the key points about our solution to the Conversational Intelligence Challenge 2 using a generative model:
1. The goal of the challenge was to build an AI assistant that can carry out a coherent multi-turn conversation by drawing from a provided persona.
2. We used a generative model based on Transformer architecture to generate responses. The model was first pre-trained on large conversational datasets using language modeling objective.
3. For the challenge dataset, the model was fine-tuned on persona-conditioned conversations. The persona description and previous conversation history was fed as input to condition the response generation.
4. Beam search with length penalty was used during inference to produce diverse and coherent multi-sentence responses
The Rise Of Conversational AI with David LowDatabricks
In this fast-paced world, customers demand ease and efficiency when they talk to a company. Here comes “Chatbot”, an automated conversational agent which conducts conversations via text or voice.
For this talk, I will be starting with the current state of Conversational Intelligence and some common Python libraries used in building chatbots. Various approaches of building conversation engine such as pattern matching, word embedding and long short-term memory (LSTM) models will be discussed. At the same time, I will present the next generation of Conversational AI that focuses on Question Answering and perform a live-demo of such a system.
After the demo, the inner workings will be explained and relevant resources (including a Python framework for conversational AI research and datasets) will be introduced to the participants. Lastly, I will also share my experience launching commercial chatbots with Fortune 500 clients and a few pitfalls one should be aware of before concluding the talk. Key takeaways:
• Get to know the current state of Conversational AI
• Approaches from pattern matching to generative model; AIML / regex, Word-embeddings, Bi-directional LSTM
• The next generation of conversational AI: ParlAI, SQuAD, bAbi Tasks, MCTest etc. Example architecture: BiDAF, Dynamic Memory Network
• What we learned after launching 3 commercial chatbots with a bank and two insurance companies.
• Challenges: Compliance / General Intelligence / Answer Generation
• A Good Conversational UX is the combination of Art and Science.

Description, Identity, and Rhetoric: Visualizing the Available Means of Pers...Spelman College
This powerpoint contextualizes the importance of narration and description through their relationship to rhetoric and identity. Argumentation and rhetorical analysis are described as heuristics for rhetoric. Slides on rhetorical analysis link such inquiry to self-reflection and the visualization of opportunities to connect to audiences, as well as invites occasions for argumentation. Lecture notes, discussion questions, free-writing exercises, and collaborative workshop activities enable students to sharpen their narration/description skills. This powerpoint does not exhaustively cover specific narration techniques such as utilizing active verbs to create narrative perspective, but students are encouraged to reflect on this strategy throughout the slides "showing not telling."
Some slides are in conversation with the textbooks Envision (2nd Edition) by Christine Alfano and Alyssa O'Brien, and Christine Latterell's Remix (2nd Edition). Instructors may omit slides that deal with these external materials. The contents of this presentation may be approached as a series of interactive discussions intended to be spread out over the course of two to three class periods.
The document discusses pragmatic markers. It begins with an agenda that includes defining pragmatic markers, activities to analyze their use, and examining markers in different languages. It then defines pragmatic markers based on their phonological, syntactic, semantic, functional, and sociolinguistic features. Their textual and interpersonal functions are also defined. Examples are provided to categorize the functions of markers. The discussion then explores markers in languages such as Chinese, Japanese, and Thai, noting common markers and their frequencies and uses in each language.
This document provides tips for lesson design from Jon Corippo. It recommends focusing lessons on specific, positive, and transformative goals that take students out of their comfort zone. Lessons should include 4-6 repetitions to move students from knowing to understanding a concept. Formative assessments with immediate feedback are emphasized over grades. Examples are provided of lesson plans incorporating these principles across various subjects like language arts, math, and technology.
Handling and Mining Linguistic Variation in UGCLeon Derczynski
This document discusses user-generated content (UGC) found on social media and the linguistic variation present within it. It notes that UGC comes directly from end users without editing and contains nonstandard spelling, grammar, slang, and abbreviations.

Finding question answer pairs from online forumT.K. Loong
This document proposes methods for finding question-answer pairs in online forums. It presents a rule-based and machine learning approach called labeled sequential pattern for question detection that achieves an F1 score of 97.4%. For answer detection, it enhances traditional information retrieval methods like cosine similarity and language models with a graph-based propagation approach. This approach constructs a graph based on the generation relationships between candidate answers and incorporates forum-specific features and author authority to assign weights for propagating scores. The integrated approaches of question detection, answer detection and graph-based ranking aim to effectively extract question-answer pairs from the large amounts of unstructured user-generated content in online forums.

This paper contributes a noun phrase-annotated SMS corpus and proposes a weak semi-Markov CRF model for noun phrase chunking in informal text. The weak semi-CRF model improves training speed over linear-CRF and semi-CRF models while maintaining similar accuracy. Experiments on the SMS corpus show the weak semi-CRF achieves F1 scores comparable to other models but trains faster, especially with larger training data sizes.
This document presents a new method for automatically detecting false friends between Spanish and Portuguese using word embeddings. The method builds word vector spaces for each language using word2vec, finds a linear transformation between the spaces, and measures vector distances to classify word pairs as cognates or false friends. In experiments on a dataset of 710 word pairs, the method achieved state-of-the-art accuracy of 77.28% and high coverage of 97.91%, outperforming previous work. Future work will explore using different word embeddings and fine-grained classifications of partial false friends.
This document describes a Spanish language corpus for humor analysis that was created through crowd-sourcing annotations. Over 27,000 tweets were collected from humorous accounts and annotated through a web interface. The corpus contains over 100,000 annotations of the tweets' humor and funniness. Inter-annotator agreement was higher for this corpus than a previous Spanish humor corpus. The dataset will help analyze subjectivity in humor and was used in a shared task on humor classification and funniness prediction.
This document discusses position bias in instructor interventions in MOOC discussion forums. It finds that instructors are more likely to intervene in threads that appear higher on the discussion forum user interface due to their recent activity. To address this, it proposes a debiased classifier that weights examples based on their propensity for intervention. It finds this approach identifies intervention opportunities that were overlooked due to position bias. The debiased classifier outperforms a standard classifier on several metrics, demonstrating it can better predict unbiased intervention needs.
The document summarizes the history and current state of the ACL Anthology, a repository of publications from ACL-sponsored conferences. It discusses how the Anthology was established in 2001 and is now maintained by volunteers, containing over 45,000 papers. The presentation calls for community involvement to help future-proof the Anthology through efforts like migrating its infrastructure and improving documentation. It also proposes hosting the Anthology on the main ACL website and recruiting a new editor.
The document presents SAMSA, a new automatic evaluation measure for structural text simplification. SAMSA uses semantic parsing to measure the preservation of semantic structures and relations between an original text and its simplified version. It correlates significantly better with human judgments of meaning preservation and structural simplicity than prior reference-based metrics. SAMSA is the first evaluation method designed specifically for structural simplification operations like sentence splitting.
(1) Sequicity is a framework that simplifies task-oriented dialogue systems using single sequence-to-sequence architectures.
(2) It formalizes dialogues as sequences of belief spans and responses and decodes them in two stages: generating a belief span followed by a response.
(3) An experiment on two datasets found that a two-stage CopyNet instantiation of Sequicity outperformed several baselines in effectiveness, efficiency and handling out-of-vocabulary requests.
The document summarizes a study that explored how people's strategies for giving commands to a robot change over time during a collaborative navigation task. Ten participants each directed a robot for one hour via dialogue. Initially, participants predominantly used metric units like distances in their commands, but over time their commands increasingly referred to environmental landmarks. The study collected audio, text, and robot data to analyze parameters in commands. Future work aims to automate dialogue response generation based on this data.
The document describes a system for estimating emotion intensity in tweets. It takes a lexicon-based and word vector-based approach to create sentence embeddings for tweets. Various regression models are trained and an ensemble is used to predict emotion intensity scores between 0-1 for anger, sadness, joy and fear. The system achieved third place in predicting emotion intensity and second place for intensities over 0.5. Future work involves using contextual sentence embeddings to improve predictions.
This document describes Toshiba's machine translation system submitted to the WAT2015 workshop. It discusses using statistical post-editing (SPE) to improve rule-based machine translation (RBMT) output, as well as combining SPE and SMT systems using reranking with recurrent neural network language models. Experimental results show that the combined system achieved the best BLEU and RIBES scores compared to the individual SPE and SMT systems on several language pairs, including Japanese-English and Chinese-Japanese. However, human evaluation correlations were not entirely clear.
The document describes improvements made to the KyotoEBMT machine translation system. It discusses using forest parsing of input sentences to handle parsing errors and syntactic divergences. It also describes using the Nile alignment tool along with constituent parsing to improve word alignments from the training corpus. New features were added and the reranking was improved by incorporating a neural machine translation-based bilingual language model.

This document evaluates several neural machine translation models for English to Japanese translation. It finds that simple neural models outperform statistical machine translation baselines. Soft attention models with LSTM units performed best. However, training these models on pre-reordered data hurt performance. The neural models tended to produce grammatically correct but incomplete translations by omitting information. Replacing unknown words helped some models but more sophisticated solutions are needed for models trained on natural order data.
This document evaluates various neural machine translation models for English to Japanese translation. It compares different network architectures, recurrent units, and training data configurations. Results show that soft-attention models outperformed multi-layer encoder-decoder models, and training on pre-reordered data hurt performance. Neural machine translation models tended to generate grammatically correct but incomplete translations.
This document describes NAVER's machine translation systems for the WAT 2015 evaluation. For English-to-Japanese translation, the best system combined tree-to-string syntax-based machine translation with neural machine translation re-ranking, achieving a BLEU score of 34.60. For Korean-to-Japanese translation, the top system used phrase-based machine translation and neural machine translation re-ranking, obtaining a BLEU score of 71.38. The document also analyzes the effectiveness of character-level tokenization and other techniques for neural machine translation.
Toshiba presented their machine translation system for the WAT2015 workshop. Their system uses statistical post-editing (SPE) to correct rule-based machine translation (RBMT) output. It also combines SPE and phrase-based statistical machine translation (SMT) results by reranking the merged n-best lists using a recurrent neural network language model. Evaluation showed the combined system achieved the best results on most language pairs compared to SPE and SMT individually. Analysis of system selections by the combination found it primarily chose translations from SPE.
The document summarizes research conducted by NICT at the WAT 2015 workshop. They tested simple translation techniques like reverse pre-reordering for Japanese-to-English and character-based translation for Korean-to-Japanese. The techniques were found to work effectively and the researchers encourage wider use of these techniques if confirmed through human evaluation at the workshop.
Neural reranking of machine translation output improves both automatic metrics and subjective human evaluations of translation quality. The document analyzes reranking results from a statistical machine translation system using an attentional neural machine translation model. Reranking corrected errors related to reordering, insertion, deletion, substitution and conjugation. Specifically, it improved phrasal reordering, auxiliary verb insertion/deletion, and coordinate structures. The gains were mainly in grammatical aspects rather than lexical selection. While reranking is shown to be effective, questions remain about comparing it to pure neural machine translation and neural language models.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

How to Fix the Import Error in the Odoo 17Celine George
An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.

2. Motivation
● Humans appear to organize and remember everyday
experiences by imposing a narrative structure on them
● Thus many genres of natural language exhibit narrative
structure
● Widely agreed that narrative understanding requires
○ Modelling protagonist goals
○ Tracking their outcomes
● First person social media stories full of expressions of
desires and outcome descriptions
First-person blog story

3. First Person Story: Live Journal
3
I dropped something and it was dark, he bent with his cell
phone light to help me look for it. We spoke a little, but it
was loud and not suited for conversation there.
I had hoped to ask him to join me for a drink or
something after the show (if my courage would allow
such a thing)
but he left before the end and I didn’t see him after that.
Maybe I’ll try missed connections lol.
4. Goal
● Identify goal and desire expressions in first-person
narratives
○ E.g. “had hoped to”
● Infer from the surrounding text whether the desire is
○ Fulfilled
○ Unfulfilled

Unfulfilled
6. First Person Desires

People did seem pleased to see me but all I [wanted to] do was talk to a particular friend.
I [wished to] meet new people and to get out of my own made misery and turn myself into a more
sociable human being for the sake of mental health alone.
I'm off this weekend and had really [hoped to] get out and dance.
We [decided to] just go for a walk and look at all the sunflowers in the neighborhood.
I [couldn't wait to] get out of our cheap and somewhat charming hotel and show James a little bit of
Paris.
We drove for just over an hour and [aimed to] get to Trinity beach to set up for the night.
She called the pastor, and he had time, too, so, we [arranged to] meet Saturday at 9am.
Even though my deadline wasn't until 4 p.m., I [needed to] write the story as quickly as possible.

to speak, and I can't even
remember what I said, but
people were very happy
and proud of me for
saying what I wanted to
say.
18. Discourse Features

Discourse Treebank as:
○ Violated-Expectation (31): e.g.
although, rather, yet, but
○ Meeting-Expectation (15):
accordingly, so, ultimately, finally
○ Neutral : none of these appear

21. Classification Models
● Four types of features
○ Motivated by narrative characteristics
○ Ablation experiments
● Method
○ LSTM for sentence embeddings
○ Three-layer RNN for classification
■ Suitable for sequence learning
■ Encode the order of the sentences to distinguish between prior and post
context
21
22. Generating Sentence Embeddings
● Two approaches
○ Skip-Thought: Using pre-trained skip-thought model (Kiros et al., 2015) as the
embeddings
■ Concatenates features, if any, with embeddings
■ Uses LSTM to generate a single representation
○ CNN-RNN: Using 1-dimensional convolution with max-over-time pooling
introduced (Kim, 2014) to generate the sentence embedding
■ Uses LSTM to generate a single representation
■ Used Google News Vectors (Mikolov et al., 2013) for word embedding

○ In order to compare more directly to previous work
○ Five verbal patterns
■ wanted to, hoped to, wished to, couldn’t wait to, decided to
○ Fulfilled: 1,366
○ Unfulfilled: 953
○ Train (1,656), Dev (327), and Test (336) sets
24
26. Effects of Prior and Post Context

Fulfilled class as compared to Unfulfilled
● Same in annotations
○ Data labeled Fulfilled by two annotators
■ 64% labeled Unknown from the context
■ only 36% labeled Unfulfilled
○ Data labeled Unfulfilled
■ 49% labeled Unknown from the context
■ 51% labeled Fulfilled
28
29. Comparison to Previous Work Datasets
