shapiro-1978-path-based | https://aclanthology.org/T78-1031 | Path-Based and Node-Based Inference in Semantic Networks | Two styles of performing inference in semantic networks are presented and compared. Path-based inference allows an arc or a path of arcs between two given nodes to be inferred from the existence of another specified path between the same two nodes. Path-based inference rules may be written using a binary relational calculus notation. Node-based inference allows a structure of nodes to be inferred from the existence of an instance of a pattern of node structures. Node-based inference rules can be constructed in a semantic network using a variant of a predicate calculus notation. Path-based inference is more efficient, while node-based inference is more general. A method is described of combining the two styles in a single system in order to take advantage of the strengths of each. Applications of path-based inference rules to the representation of the extensional equivalence of intensional concepts, and to the explication of inheritance in hierarchies are sketched.

shnarch-etal-2020-unsupervised | https://aclanthology.org/2020.findings-emnlp.243 | Unsupervised Expressive Rules Provide Explainability and Assist Human Experts Grasping New Domains | Approaching new data can be quite deterrent; you do not know how your categories of interest are realized in it, commonly, there is no labeled data at hand, and the performance of domain adaptation methods is unsatisfactory. Aiming to assist domain experts in their first steps into a new task over a new corpus, we present an unsupervised approach to reveal complex rules which cluster the unexplored corpus by its prominent categories (or facets). These rules are human-readable, thus providing an important ingredient which has become in short supply lately-explainability. Each rule provides an explanation for the commonality of all the texts it clusters together. We present an extensive evaluation of the usefulness of these rules in identifying target categories, as well as a user study which assesses their interpretability. | false | [] | [] | null | null | null | null | 2020 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
yu-etal-2018-syntaxsqlnet | https://aclanthology.org/D18-1193 | SyntaxSQLNet: Syntax Tree Networks for Complex and Cross-Domain Text-to-SQL Task | Most existing studies in text-to-SQL tasks do not require generating complex SQL queries with multiple clauses or sub-queries, and generalizing to new, unseen databases. In this paper we propose SyntaxSQLNet, a syntax tree network to address the complex and crossdomain text-to-SQL generation task. Syn-taxSQLNet employs a SQL specific syntax tree-based decoder with SQL generation path history and table-aware column attention encoders. We evaluate SyntaxSQLNet on a new large-scale text-to-SQL corpus containing databases with multiple tables and complex SQL queries containing multiple SQL clauses and nested queries. We use a database split setting where databases in the test set are unseen during training. Experimental results show that SyntaxSQLNet can handle a significantly greater number of complex SQL examples than prior work, outperforming the previous state-of-the-art model by 9.5% in exact matching accuracy. To our knowledge, we are the first to study this complex text-to-SQL task.

shen-etal-2017-conditional | https://aclanthology.org/P17-2080 | A Conditional Variational Framework for Dialog Generation | Deep latent variable models have been shown to facilitate the response generation for open-domain dialog systems. However, these latent variables are highly randomized, leading to uncontrollable generated responses. In this paper, we propose a framework allowing conditional response generation based on specific attributes. These attributes can be either manually assigned or automatically detected. Moreover, the dialog states for both speakers are modeled separately in order to reflect personal features. We validate this framework on two different scenarios, where the attribute refers to genericness and sentiment states respectively. The experiment result testified the potential of our model, where meaningful responses can be generated in accordance with the specified attributes. | false | [] | [] | null | null | null | This work was supported by the National Natural Science of China under Grant No. 61602451, 61672445 and JSPS KAKENHI Grant Numbers 15H02754, 16K12546. | 2017 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
tursun-cakici-2017-noisy | https://aclanthology.org/W17-4412 | Noisy Uyghur Text Normalization | Uyghur is the second largest and most actively used social media language in China. However, a non-negligible part of Uyghur text appearing in social media is unsystematically written with the Latin alphabet, and it continues to increase in size. Uyghur text in this format is incomprehensible and ambiguous even to native Uyghur speakers. In addition, Uyghur texts in this form lack the potential for any kind of advancement for the NLP tasks related to the Uyghur language. Restoring and preventing noisy Uyghur text written with unsystematic Latin alphabets will be essential to the protection of Uyghur language and improving the accuracy of Uyghur NLP tasks. To this purpose, in this work we propose and compare the noisy channel model and the neural encoderdecoder model as normalizing methods. | false | [] | [] | null | null | null | We gratefully acknowledge the support of NVIDIA Corporation with the donation of the Tesla K40 GPU used for this research. | 2017 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
baldridge-kruijff-2002-coupling | https://aclanthology.org/P02-1041 | Coupling CCG and Hybrid Logic Dependency Semantics | Categorial grammar has traditionally used the λ-calculus to represent meaning. We present an alternative, dependency-based perspective on linguistic meaning and situate it in the computational setting. This perspective is formalized in terms of hybrid logic and has a rich yet perspicuous propositional ontology that enables a wide variety of semantic phenomena to be represented in a single meaning formalism. Finally, we show how we can couple this formalization to Combinatory Categorial Grammar to produce interpretations compositionally. | false | [] | [] | null | null | null | We would like to thank Patrick Blackburn, Johan Bos, Nissim Francez, Alex Lascarides, Mark Steedman, Bonnie Webber and the ACL reviewers for helpful comments on earlier versions of this paper.

li-etal-2021-retrieve | https://aclanthology.org/2021.findings-acl.39 | Retrieve \& Memorize: Dialog Policy Learning with Multi-Action Memory | Dialogue policy learning, a subtask that determines the content of system response generation and then the degree of task completion, is essential for task-oriented dialogue systems. However, the unbalanced distribution of system actions in dialogue datasets often causes difficulty in learning to generate desired actions and responses. In this paper, we propose a retrieve-and-memorize framework to enhance the learning of system actions. Specially, we first design a neural context-aware retrieval module to retrieve multiple candidate system actions from the training set given a dialogue context. Then, we propose a memoryaugmented multi-decoder network to generate the system actions conditioned on the candidate actions, which allows the network to adaptively select key information in the candidate actions and ignore noises. We conduct experiments on the large-scale multi-domain task-oriented dialogue dataset MultiWOZ 2.0 and MultiWOZ 2.1. Experimental results show that our method achieves competitive performance among several state-of-the-art models in the context-to-response generation task. | false | [] | [] | null | null | null | The paper was supported by the National Natural Science Foundation of China (No.61906217) and the Program for Guangdong Introducing Innovative and Entrepreneurial Teams (No.2017ZT07X355). | 2021 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
wu-etal-2019-open | https://aclanthology.org/D19-1021 | Open Relation Extraction: Relational Knowledge Transfer from Supervised Data to Unsupervised Data | Open relation extraction (OpenRE) aims to extract relational facts from the open-domain corpus. To this end, it discovers relation patterns between named entities and then clusters those semantically equivalent patterns into a united relation cluster. Most OpenRE methods typically confine themselves to unsupervised paradigms, without taking advantage of existing relational facts in knowledge bases (KBs) and their high-quality labeled instances. To address this issue, we propose Relational Siamese Networks (RSNs) to learn similarity metrics of relations from labeled data of pre-defined relations, and then transfer the relational knowledge to identify novel relations in unlabeled data. Experiment results on two real-world datasets show that our framework can achieve significant improvements as compared with other state-of-the-art methods.

sevgili-etal-2019-improving | https://aclanthology.org/P19-2044 | Improving Neural Entity Disambiguation with Graph Embeddings | Entity Disambiguation (ED) is the task of linking an ambiguous entity mention to a corresponding entry in a knowledge base. Current methods have mostly focused on unstructured text data to learn representations of entities, however, there is structured information in the knowledge base itself that should be useful to disambiguate entities. In this work, we propose a method that uses graph embeddings for integrating structured information from the knowledge base with unstructured information from text-based representations. Our experiments confirm that graph embeddings trained on a graph of hyperlinks between Wikipedia articles improve the performances of simple feed-forward neural ED model and a state-ofthe-art neural ED system. | false | [] | [] | null | null | null | We thank the SRW mentor Matt Gardner and anonymous reviewers for their most useful feedback on this work.

wang-etal-2015-feature | https://aclanthology.org/P15-1110 | Feature Optimization for Constituent Parsing via Neural Networks | The performance of discriminative constituent parsing relies crucially on feature engineering, and effective features usually have to be carefully selected through a painful manual process. In this paper, we propose to automatically learn a set of effective features via neural networks. Specifically, we build a feedforward neural network model, which takes as input a few primitive units (words, POS tags and certain contextual tokens) from the local context, induces the feature representation in the hidden layer and makes parsing predictions in the output layer. The network simultaneously learns the feature representation and the prediction model parameters using a back propagation algorithm. By pre-training the model on a large amount of automatically parsed data, and then fine-tuning on the manually annotated Treebank data, our parser achieves the highest F 1 score at 86.6% on Chinese Treebank 5.1, and a competitive F 1 score at 90.7% on English Treebank. More importantly, our parser generalizes well on cross-domain test sets, where we significantly outperform Berkeley parser by 3.4 points on average for Chinese and 2.5 points for English. | false | [] | [] | null | null | null | We thank the anonymous reviewers for comments.

das-bandyopadhyay-2010-towards | https://aclanthology.org/Y10-1092 | Towards the Global SentiWordNet | The discipline where sentiment/opinion/emotion has been identified and classified in human written text is well known as sentiment analysis. A typical computational approach to sentiment analysis starts with prior polarity lexicons where entries are tagged with their prior out of context polarity as human beings perceive using cognitive knowledge. Till date, all research efforts found in sentiment analysis literature deal mostly with English texts. In this article, we propose an interactive gaming (Dr Sentiment) technology to create and validate SentiWordNet in 56 languages by involving Internet population. Dr Sentiment is a fictitious character, interact with players using series of questions and finally reveal the behavioral or sentimental status of any player and store the lexicons as the players polarized during playing. The interactive gaming technology is then compared with other multiple automatic linguistics techniques like, WordNet based, dictionary based, corpus based or generative approaches for generating SentiWordNet(s) for Indian languages and other International languages as well. A number of automatic, semiautomatic and manual validations and evaluation methodologies have been adopted to measure the coverage and credibility of the developed SentiWordNet(s). | false | [] | [] | null | null | null | null | 2010 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

trippel-etal-2014-towards | http://www.lrec-conf.org/proceedings/lrec2014/pdf/1011_Paper.pdf | Towards automatic quality assessment of component metadata | Measuring the quality of metadata is only possible by assessing the quality of the underlying schema and the metadata instance. We propose some factors that are measurable automatically for metadata according to the CMD framework, taking into account the variability of schemas that can be defined in this framework. The factors include among others the number of elements, the (re-)use of reusable components, the number of filled in elements. The resulting score can serve as an indicator of the overall quality of the CMD instance, used for feedback to metadata providers or to provide an overview of the overall quality of metadata within a repository. The score is independent of specific schemas and generalizable. An overall assessment of harvested metadata is provided in form of statistical summaries and the distribution, based on a corpus of harvested metadata. The score is implemented in XQuery and can be used in tools, editors and repositories. | false | [] | [] | null | null | null | null | 2014 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

Although sentence extraction has previously been evaluated based only on precision of a single sentence, sentence concatenations in the summaries should be evaluated as well. We have evaluated the appropriateness of sentence concatenations in summaries by using evaluation measures used for evaluating word concatenations in summaries through word extraction.

chakrabarty-etal-2021-mermaid | https://aclanthology.org/2021.naacl-main.336 | MERMAID: Metaphor Generation with Symbolism and Discriminative Decoding | Generating metaphors is a challenging task as it requires a proper understanding of abstract concepts, making connections between unrelated concepts, and deviating from the literal meaning. In this paper, we aim to generate a metaphoric sentence given a literal expression by replacing relevant verbs. Based on a theoretically-grounded connection between metaphors and symbols, we propose a method to automatically construct a parallel corpus by transforming a large number of metaphorical sentences from the Gutenberg Poetry corpus (Jacobs, 2018) to their literal counterpart using recent advances in masked language modeling coupled with commonsense inference. For the generation task, we incorporate a metaphor discriminator to guide the decoding of a sequence to sequence model finetuned on our parallel data to generate high quality metaphors. Human evaluation on an independent test set of literal statements shows that our best model generates metaphors better than three well-crafted baselines 66% of the time on average. Moreover, a task-based evaluation shows that human-written poems enhanced with metaphors proposed by our model are preferred 68% of the time compared to poems without metaphors. | false | [] | [] | null | null | null | This work was supported in part by the MCS program under Cooperative Agreement N66001-19-2-4032, and the CwC program under Contract W911NF-15-1-0543 with the US Defense Advanced Research Projects Agency (DARPA).

schrodt-2020-keynote | https://aclanthology.org/2020.aespen-1.3 | Keynote Abstract: Current Open Questions for Operational Event Data | In this brief keynote, I will address what I see as five major issues in terms of development for operational event data sets (that is, event data intended for real time monitoring and forecasting, rather than purely for academic research). First, there are no currently active real time systems with fully open and transparent pipelines: instead, one or more components are proprietary. Ideally we need several of these, using different approaches (and in particular, comparisons between classical dictionary-and rule-based coders versus newer coders based on machine-learning approaches). Second, the CAMEO event ontology needs to be replaced by a more general system that includes, for example, political codes for electoral competition, legislative debate, and parliamentary coalition formation, as well as a robust set of codes for non-political events such as natural disasters, disease, and economic dislocations. Third, the issue of duplicate stories needs to be addressed -for example, the ICEWS system can generate as many as 150 coded events from a single occurrence on the groundeither to reduce these sets of related stories to a single set of events, or at least to label clusters of related stories as is already done in a number of systems (for example European Media Monitor).
Fourth, a systematic analysis needs to be done as to the additional information provided by hundreds of highly local sources (which have varying degrees of varacity and independence from states and local elites) as opposed to a relatively small number of international sources: obviously this will vary depending on the specific question being asked but has yet to be addressed at all. Finally, and this will overlap with academic work, a number of open benchmarks need to be constructed for the calibration of both coding systems and resulting models: these could be historical but need to include an easily licensed (or open) very large set of texts covering a substantial period of time, probably along the lines of the Linguistics Data Consortium Gigaword sets; if licensed, these need to be accessible to individual researchers and NGOs, not just academic institutions. | false | [] | [] | null | null | null | null | 2020 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

Various corpora have been collected using a well-equipped recording environment, such as voice recording in an anechoic room. However, due to geographical and expense issues, it is impossible to use such a perfect recording environment for collecting all existing dialects. To address this problem, we used web-based recording and crowdsourcing platforms to construct a crowdsourced parallel speech corpus of Japanese dialects (CPJD corpus) including parallel text and speech data of 21 Japanese dialects. We recruited native dialect speakers on the crowdsourcing platform, and the hired speakers recorded their dialect speech using their personal computer or smartphone in their homes.

jiang-zhai-2006-exploiting | https://aclanthology.org/N06-1010 | Exploiting Domain Structure for Named Entity Recognition | Named Entity Recognition (NER) is a fundamental task in text mining and natural language understanding. Current approaches to NER (mostly based on supervised learning) perform well on domains similar to the training domain, but they tend to adapt poorly to slightly different domains. We present several strategies for exploiting the domain structure in the training data to learn a more robust named entity recognizer that can perform well on a new domain. First, we propose a simple yet effective way to automatically rank features based on their generalizabilities across domains. We then train a classifier with strong emphasis on the most generalizable features. This emphasis is imposed by putting a rank-based prior on a logistic regression model. We further propose a domain-aware cross validation strategy to help choose an appropriate parameter for the rank-based prior. We evaluated the proposed method with a task of recognizing named entities (genes) in biology text involving three species. The experiment results show that the new domainaware approach outperforms a state-ofthe-art baseline method in adapting to new domains, especially when there is a great difference between the new domain and the training domain. | false | [] | [] | null | null | null | This work was in part supported by the National Science Foundation under award numbers 0425852, 0347933, and 0428472.

We propose a solution based on similarity-based smoothing, where the probability of new PPs is estimated with information from similar examples generated using a thesaurus. Three thesauruses are compared on this task: two existing generic thesauruses and a new specialist PP thesaurus tailored for this problem. We also compare three smoothing techniques for prepositional phrases. We find that the similarity scores provided by the thesaurus tend to weight distant neighbours too highly, and describe a better score based on the rank of a word in the list of similar words. Our smoothing methods are applied to an existing PP attachment model and we obtain significant improvements over the baseline. | false | [] | [] | null | null | null | Many thanks to Julie Weeds and Adam Kilgarriff for providing the specialist and WASPS thesauruses, and for useful discussions.

gu-etal-2018-language | https://aclanthology.org/D18-1493 | Language Modeling with Sparse Product of Sememe Experts | Most language modeling methods rely on large-scale data to statistically learn the sequential patterns of words. In this paper, we argue that words are atomic language units but not necessarily atomic semantic units. Inspired by HowNet, we use sememes, the minimum semantic units in human languages, to represent the implicit semantics behind words for language modeling, named Sememe-Driven Language Model (SDLM). More specifically, to predict the next word, SDLM first estimates the sememe distribution given textual context. Afterwards, it regards each sememe as a distinct semantic expert, and these experts jointly identify the most probable senses and the corresponding word. In this way, SDLM enables language models to work beyond word-level manipulation to fine-grained sememe-level semantics, and offers us more powerful tools to fine-tune language models and improve the interpretability as well as the robustness of language models. Experiments on language modeling and the downstream application of headline generation demonstrate the significant effectiveness of SDLM.

zhang-bansal-2021-finding | https://aclanthology.org/2021.emnlp-main.531 | Finding a Balanced Degree of Automation for Summary Evaluation | Human evaluation for summarization tasks is reliable but brings in issues of reproducibility and high costs. Automatic metrics are cheap and reproducible but sometimes poorly correlated with human judgment. In this work, we propose flexible semiautomatic to automatic summary evaluation metrics, following the Pyramid human evaluation method. Semi-automatic Lite 2 Pyramid retains the reusable human-labeled Summary Content Units (SCUs) for reference(s) but replaces the manual work of judging SCUs' presence in system summaries with a natural language inference (NLI) model. Fully automatic Lite 3 Pyramid further substitutes SCUs with automatically extracted Semantic Triplet Units (STUs) via a semantic role labeling (SRL) model. Finally, we propose in-between metrics, Lite 2.x Pyramid, where we use a simple regressor to predict how well the STUs can simulate SCUs and retain SCUs that are more difficult to simulate, which provides a smooth transition and balance between automation and manual evaluation. Comparing to 15 existing metrics, we evaluate human-metric correlations on 3 existing meta-evaluation datasets and our newlycollected PyrXSum (with 100/10 XSum examples/systems). It shows that Lite 2 Pyramid consistently has the best summary-level correlations; Lite 3 Pyramid works better than or comparable to other automatic metrics; Lite 2.x Pyramid trades off small correlation drops for larger manual effort reduction, which can reduce costs for future data collection. 1 | false | [] | [] | null | null | null | We thank the reviewers for their helpful comments.

Fine-grained adjustments to a model's architecture or training recipe can mean the difference between a positive and negative research result or between a state-of-the-art and underperforming system. While recent literature has proposed methods for automatic hyperparameter optimization (HPO), there has been limited work on applying these methods to neural machine translation (NMT), due in part to the high costs associated with experiments that train large numbers of model variants. To facilitate research in this space, we introduce a lookup-based approach that uses a library of pre-trained models for fast, low cost HPO experimentation. Our contributions include (1) the release of a large collection of trained NMT models covering a wide range of hyperparameters, (2) the proposal of targeted metrics for evaluating HPO methods on NMT, and (3) a reproducible benchmark of several HPO methods against our model library, including novel graph-based and multiobjective methods. | false | [] | [] | null | null | null | This work is supported in part by an Amazon Research Award and an IARPA MATERIAL grant.

Depending on system choices, the affinity scores can be further used in clustering or mention ranking. Our experiments show that a standard hierarchical clustering using the scores produces state-of-art results with MUC and B 3 metrics on the English portion of CoNLL 2012 Shared Task.

The applied evaluation metrics and resulting design principles are often obscure, emerge by trial-and-error, and are highly context dependent. This paper introduces data-driven methods for obtaining reliable objective functions for system design. In particular, we test whether an objective function obtained from Wizard-of-Oz (WOZ) data is a valid estimate of real users' preferences. We test this in a test-retest comparison between the model obtained from the WOZ study and the models obtained when testing with real users. We can show that, despite a low fit to the initial data, the objective function obtained from WOZ data makes accurate predictions for automatic dialogue evaluation, and, when automatically optimising a policy using these predictions, the improvement over a strategy simply mimicking the data becomes clear from an error analysis. | false | [] | [] | null | null | null | This work was partially funded by the International Research Training Group Language Technology and Cognitive Systems, Saarland University, and by EPSRC project number EP/E019501/1.

carl-etal-2005-reversible | https://aclanthology.org/2005.mtsummit-ebmt.3 | Reversible Template-based Shake \& Bake Generation | Corpus-based MT systems that analyse and generalise texts beyond the surface forms of words require generation tools to regenerate the various internal representations into valid target language (TL) sentences. While the generation of word-forms from lemmas is probably the last step in every text generation process at its very bottom end, token-generation cannot be accomplished without structural and morpho-syntactic knowledge of the sentence to be generated. As in many other MT models, this knowledge is composed of a target language model and a bag of information transferred from the source language. In this paper we establish an abstracted, linguistically informed, target language model. We use a tagger, a lemmatiser and a parser to infer a template grammar from the TL corpus. Given a linguistically informed TL model, the aim is to see what need be provided from the transfer module for generation. During computation of the template grammar, we simultaneously build up for each TL sentence the content of the bag such that the sentence can be deterministically reproduced. In this way we control the completeness of the approach and will have an idea of what pieces of information we need to code in the TL bag. | false | [] | [] | null | null | null | null | 2005 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

In this paper, we propose a novel time-aware KB embedding approach taking advantage of the happening time of facts. Specifically, we use temporal order constraints to model transformation between time-sensitive relations and enforce the embeddings to be temporally consistent and more accurate. We empirically evaluate our approach in two tasks of link prediction and triple classification. Experimental results show that our method outperforms other baselines on the two tasks consistently. | false | [] | [] | null | null | null | This research is supported by National Key Basic Research Program of China (No.2014CB340504) and National Natural Science Foundation of China (No.61375074,61273318).

tang-etal-2020-syntactic | https://aclanthology.org/2020.findings-emnlp.69 | Syntactic and Semantic-driven Learning for Open Information Extraction | One of the biggest bottlenecks in building accurate, high coverage neural open IE systems is the need for large labelled corpora. The diversity of open domain corpora and the variety of natural language expressions further exacerbate this problem. In this paper, we propose a syntactic and semantic-driven learning approach, which can learn neural open IE models without any human-labelled data by leveraging syntactic and semantic knowledge as noisier, higher-level supervisions. Specifically, we first employ syntactic patterns as data labelling functions and pretrain a base model using the generated labels. Then we propose a syntactic and semantic-driven reinforcement learning algorithm, which can effectively generalize the base model to open situations with high accuracy. Experimental results show that our approach significantly outperforms the supervised counterparts, and can even achieve competitive performance to supervised stateof-the-art (SoA) model. * Corresponding author Sentences Pattern-based Data labeling Syntax and Semantic Driven RL Open IE Model Noisy Training Corpus [Parragon] ARG1 [operates] P [more than 35 markets] ARG2 and has 10 offices.

shen-etal-2020-blank | https://aclanthology.org/2020.emnlp-main.420 | Blank Language Models | We propose Blank Language Model (BLM), a model that generates sequences by dynamically creating and filling in blanks. The blanks control which part of the sequence to expand, making BLM ideal for a variety of text editing and rewriting tasks. The model can start from a single blank or partially completed text with blanks at specified locations. It iteratively determines which word to place in a blank and whether to insert new blanks, and stops generating when no blanks are left to fill. BLM can be efficiently trained using a lower bound of the marginal data likelihood. On the task of filling missing text snippets, BLM significantly outperforms all other baselines in terms of both accuracy and fluency. Experiments on style transfer and damaged ancient text restoration demonstrate the potential of this framework for a wide range of applications. 1 | false | [] | [] | null | null | null | We thank all reviewers and the MIT NLP group for their thoughtful feedback. | 2020 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

First, we create multiple models for concept extraction using a variety of information extraction techniques, including knowledgebased, rule-based, and machine learning models. Next, we train a meta-classifier using stacked generalization with a feature set generated from the outputs of the individual classifiers. The meta-classifier learns to predict concepts based on information about the predictions of the component classifiers.

We show that a traditional dictionary like Den Danske Ordbog (DDO) survives well with several inconsistencies between different taxonomies of the vocabulary and that a restructuring is therefore necessary in order to compile a consistent wordnet resource on its basis. To this end, we apply Cruse's definitions for hyponymies, namely those of natural kinds (such as plants and animals) on the one hand and functional kinds (such as foods) on the other. We pursue this distinction in the development of the Danish wordnet, DanNet, which has recently been built on the basis of DDO and is made open source for all potential users at www.wordnet.dk. Not surprisingly, we conclude that cultural background influences the structure of folk taxonomies quite radically, and that wordnet builders must therefore consider these carefully in order to capture their central characteristics in a systematic way. | false | [] | [] | null | null | null | null | 2010 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
chambers-jurafsky-2011-template | https://aclanthology.org/P11-1098 | Template-Based Information Extraction without the Templates | Standard algorithms for template-based information extraction (IE) require predefined template schemas, and often labeled data, to learn to extract their slot fillers (e.g., an embassy is the Target of a Bombing template). This paper describes an approach to template-based IE that removes this requirement and performs extraction without knowing the template structure in advance. Our algorithm instead learns the template structure automatically from raw text, inducing template schemas as sets of linked events (e.g., bombings include detonate, set off, and destroy events) associated with semantic roles. We also solve the standard IE task, using the induced syntactic patterns to extract role fillers from specific documents. We evaluate on the MUC-4 terrorism dataset and show that we induce template structure very similar to handcreated gold structure, and we extract role fillers with an F1 score of .40, approaching the performance of algorithms that require full knowledge of the templates. | false | [] | [] | null | null | null | This work was supported by the National Science Foundation IIS-0811974, and this material is also based upon work supported by the Air Force Research Laboratory (AFRL) under prime contract no.

nakazawa-2015-promoting | https://aclanthology.org/2015.mtsummit-wpslt.5 | Promoting science and technology exchange using machine translation | There are plenty of useful scientific and technical documents which are written in languages other than English, and are referenced domestically. Accessing these domestic documents in other countries is very important in order to know what has been accomplished and what is needed next in the science and technology fields. However, we need to surmount the language barrier to directly access these valuable documents. One obvious way to achieve this is using machine translation systems to translate foreign documents into the users' language. Even after the long history of developing machine translation systems among East Asian languages, there is still no practical system. We have launched a project to develop practical machine translation technology for promoting science and technology exchange. As the starting point, we aim at developping Chinese ↔ Japanese practical machine translation system. In this talk, I will introduce the background, goals and status of the project.

wang-etal-2019-multi-hop | https://aclanthology.org/D19-5813 | Do Multi-hop Readers Dream of Reasoning Chains? | General Question Answering (QA) systems over texts require the multi-hop reasoning capability, i.e. the ability to reason with information collected from multiple passages to derive the answer. In this paper we conduct a systematic analysis to assess such an ability of various existing models proposed for multi-hop QA tasks. Specifically, our analysis investigates that whether providing the full reasoning chain of multiple passages, instead of just one final passage where the answer appears, could improve the performance of the existing QA models. Surprisingly, when using the additional evidence passages, the improvements of all the existing multi-hop reading approaches are rather limited, with the highest error reduction of 5.8% on F1 (corresponding to 1.3% absolute improvement) from the BERT model. To better understand whether the reasoning chains could indeed help find correct answers, we further develop a co-matchingbased method that leads to 13.1% error reduction with passage chains when applied to two of our base readers (including BERT). Our results demonstrate the existence of the potential improvement using explicit multi-hop reasoning and the necessity to develop models with better reasoning abilities. 1 * Equal contributions. 1 Code and data released at https://github.com/ helloeve/bert-co-matching. | false | [] | [] | null | null | null | We thank the anonymous reviewers for their very valuable comments and suggestions. | 2019 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

xu-etal-2021-probing | https://aclanthology.org/2021.naacl-main.7 | Probing Word Translations in the Transformer and Trading Decoder for Encoder Layers | Due to its effectiveness and performance, the Transformer translation model has attracted wide attention, most recently in terms of probing-based approaches. Previous work focuses on using or probing source linguistic features in the encoder. To date, the way word translation evolves in Transformer layers has not yet been investigated. Naively, one might assume that encoder layers capture source information while decoder layers translate. In this work, we show that this is not quite the case: translation already happens progressively in encoder layers and even in the input embeddings. More surprisingly, we find that some of the lower decoder layers do not actually do that much decoding. We show all of this in terms of a probing approach where we project representations of the layer analyzed to the final trained and frozen classifier level of the Transformer decoder to measure word translation accuracy. Our findings motivate and explain a Transformer configuration change: if translation already happens in the encoder layers, perhaps we can increase the number of encoder layers, while decreasing the number of decoder layers, boosting decoding speed, without loss in translation quality? Our experiments show that this is indeed the case: we can increase speed by up to a factor 2.3 with small gains in translation quality, while an 18-4 deep encoder configuration boosts translation quality by +1.42 BLEU (En-De) at a speed-up of 1.4. | false | [] | [] | null | null | null | We thank anonymous reviewers for their insightful comments.

For low-resource agglutinative languages including Uyghur, Kazakh, and Kyrgyz (UKK languages), in which words are manufactured via stems concatenated with several suffixes and stems are used as the representation of text content, this feature allows infinite derivatives vocabulary that leads to high uncertainty of writing forms and huge redundant features. There are major challenges of low-resource agglutinative text classification the lack of labeled data in a target domain and morphologic diversity of derivations in language structures. It is an effective solution which fine-tuning a pre-trained language model to provide meaningful and favorable-to-use feature extractors for downstream text classification tasks. To this end, we propose a low-resource agglutinative language model fine-tuning AgglutiF iT , specifically, we build a low-noise fine-tuning dataset by morphological analysis and stem extraction, then finetune the cross-lingual pre-training model on this dataset. Moreover, we propose an attentionbased fine-tuning strategy that better selects relevant semantic and syntactic information from the pre-trained language model and uses those features on downstream text classification tasks. We evaluate our methods on nine Uyghur, Kazakh, and Kyrgyz classification datasets, where they have significantly better performance compared with several strong baselines. | false | [] | [] | null | null | null | null | 2020 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
yeh-etal-2016-grammatical | https://aclanthology.org/W16-4918 | Grammatical Error Detection Based on Machine Learning for Mandarin as Second Language Learning | Mandarin is not simple language for foreigner. Even using Mandarin as the mother tongue, they have to spend more time to learn when they were child. The following issues are the reason why causes learning problem. First, the word is envolved by Hieroglyphic. So a character can express meanings independently, but become a word has another semantic. Second, the Mandarin's grammars have flexible rule and special usage. Therefore, the common grammatical errors can classify to missing, redundant, selection and disorder. In this paper, we proposed the structure of the Recurrent Neural Networks using Long Short-term memory (RNN-LSTM). It can detect the error type from the foreign learner writing. The features based on the word vector and part-of-speech vector. In the test data found that our method in the detection level of recall better than the others, even as high as 0.9755. That is because we give the possibility of greater choice in detecting errors. | false | [] | [] | null | null | null | null | 2016 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
gildea-etal-2006-factoring | https://aclanthology.org/P06-2036 | Factoring Synchronous Grammars by Sorting | Synchronous Context-Free Grammars (SCFGs) have been successfully exploited as translation models in machine translation applications. When parsing with an SCFG, computational complexity grows exponentially with the length of the rules, in the worst case. In this paper we examine the problem of factorizing each rule of an input SCFG to a generatively equivalent set of rules, each having the smallest possible length. Our algorithm works in time O(n log n), for each rule of length n. This improves upon previous results and solves an open problem about recognizing permutations that can be factored. | false | [] | [] | null | null | null | Acknowledgments This work was partially supported by NSF ITR IIS-09325646 and NSF ITR IIS-0428020. | 2006 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

papay-etal-2018-addressing | https://aclanthology.org/W18-1204 | Addressing Low-Resource Scenarios with Character-aware Embeddings | Most modern approaches to computing word embeddings assume the availability of text corpora with billions of words. In this paper, we explore a setup where only corpora with millions of words are available, and many words in any new text are out of vocabulary. This setup is both of practical interest-modeling the situation for specific domains and low-resource languages-and of psycholinguistic interest, since it corresponds much more closely to the actual experiences and challenges of human language learning and use. We evaluate skip-gram word embeddings and two types of character-based embeddings on word relatedness prediction. On large corpora, performance of both model types is equal for frequent words, but character awareness already helps for infrequent words. Consistently, on small corpora, the characterbased models perform overall better than skipgrams. The concatenation of different embeddings performs best on small corpora and robustly on large corpora. | false | [] | [] | null | null | null | Acknowledgments.

Standard linguistic accounts of meaning are impracticable for such purposes, both because they assume nonmonotonic operations such as quantifier movement, and because they lack a representation for the meaning of content words that supports efficient computation of entailment. I'll discuss practical solutions to some of these problems within a near-context free grammar formalism for a working wide-coverage parser, in current work with Mike Lewis, and show how these solutions can be usefully applied in NLP tasks. | false | [] | [] | null | null | null | null | 2013 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
coto-solano-etal-2021-towards | https://aclanthology.org/2021.udw-1.2 | Towards Universal Dependencies for Bribri | This paper presents a first attempt to apply Universal Dependencies (Nivre et al., 2016; de Marneffe et al., 2021) to Bribri, an Indigenous language from Costa Rica belonging to the Chibchan family. There is limited previous work on Bribri NLP, so we also present a proposal for a dependency parser, as well as a listing of structures that were challenging to parse (e.g. flexible word order, verbal sequences, arguments of intransitive verbs and mismatches between the tense systems of Bribri and UD). We also list some of the challenges in performing NLP with an extremely low-resource Indigenous language, including issues with tokenization, data normalization and the training of tools like POS taggers which are necessary for the parsing. In total we collected 150 sentences (760 words) from publicly available sources like grammar books and corpora. We then used a context-free grammar for the initial parse, and then applied the headfloating algorithm in Xia and Palmer (2001) to automatically generate dependency parses. This work is a first step towards building a UD treebank for Bribri, and we hope to use this tool to improve the documentation of the language and develop language-learning materials and NLP tools like chatbots and question answering-systems. Resumen Este artículo presenta un primer intento de aplicar Dependencias Universales (Nivre et al., 2016; de Marneffe et al., 2021) al bribri, una lengua indígena chibchense de Costa Rica. Dado el limitado trabajo existente en procesamiento de lenguaje natural (PLN) en bribri incluimos también una propuesta para un analizador sintáctico de dependencias, así como una lista de estructuras difíciles de analizar (e.g. palabras con orden flexible, secuencias verbales, argumentos de verbos intransitivos y diferencias entre el sistema verbal del bribri y los rasgos morfológicos de UD). También mencionamos algunos retos del PLN en lenguas indígenas extremadamente bajas en recursos, como la tokenización, la normalización de los datos y el entrenamiento de herramientas como el etiquetado gramatical, necesario para el análisis sintáctico. Se recolectaron 150 oraciones (760 palabras) de fuentes públicas como gramáticas y corpus y se usó una gramática libre de contexto para el análisis inicial. Luego se aplicó el algoritmo de flotación de cabezas de Xia y Palmer (2001) para generar automáticamente los análisis sintácticos de dependencias. Este es el primer paso hacia la construcción de un treebank de dependencias en bribri. Esperamos usar esta herramienta para mejorar la documentación de la lengua y desarrollar materiales de aprendizaje de la lengua y herramientas de PLN como chatbots y sistemas de pregunta-respuesta. | false | [] | [] | null | null | null | null | 2021 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |
rhyne-2020-reconciling | https://aclanthology.org/2020.scil-1.51 | Reconciling historical data and modern computational models in corpus creation | We live in a time of unprecedented access to linguistic data, from audio recordings to corpora of billions of words. Linguists have used these resources to advance their research and understanding of language. Historical linguistics, despite being the oldest linguistic subfield, has lagged behind in this regard. However, this is due to several unique challenges that face the subfield. Historical data is plagued by two problems: a lack of overall data due to the ravages of time and a lack of model-ready data that have gone through standard NLP processing. Barring the discovery of more texts, the former issue cannot be solved; the latter can, though it is time-consuming and resourceintensive. These problems have only begun to be addressed for well-documented language families like Indo-European, but even within these progress is slow. There have been numerous advances in synchronic models for basic NLP tasks like POS and morphological tagging. However, modern models are not designed to work with historical data: they depend on large volumes of data and pretagged training sets that are not available for the majority of historical languages. Some have found success with methods that are designed to imitate traditional historical approaches, e.g. (Bouchard-Côté et al., 2013; McMahon and McMahon, 2003; Nakleh et al., 2005), but, if we intend to use stateof-the-art computational tools, they are essentially incompatible. This is an important challenge that computational historical linguists must address if they are going to meet the standards set by both modern corpora and historical analyses. This paper approaches the issue by treating historical data in the same way as a low-resource language (Fang | false | [] | [] | null | null | null | null | 2020 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

Both parsers obtain state-of-the-art performance, and use a very simple API consisting of, minimally, two lines of Scala code. We accompany this code with a visualization library that runs the two parsers in parallel, and displays the two generated discourse trees side by side, which provides an intuitive way of comparing the two parsers. | false | [] | [] | null | null | null | This work was funded by the DARPA Big Mechanism program under ARO contract W911NF-14-1-0395. | 2015 | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false | false |

To account for the complexity of the task, we take a more 'nuanced' approach where our ConvAI dataset reflects fine-grained notions of abuse, as well as views from multiple expert annotators. We find that the distribution of abuse is vastly different compared to other commonly used datasets, with more sexually tinted aggression towards the virtual persona of these systems. Finally, we report results from bench-marking existing models against this data. Unsurprisingly, we find that there is substantial room for improvement with F1 scores below 90%.

bak-oh-2019-variational | https://aclanthology.org/D19-1202 | Variational Hierarchical User-based Conversation Model | Generating appropriate conversation responses requires careful modeling of the utterances and speakers together. Some recent approaches to response generation model both the utterances and the speakers, but these approaches tend to generate responses that are overly tailored to the speakers. To overcome this limitation, we propose a new model with a stochastic variable designed to capture the speaker information and deliver it to the conversational context. An important part of this model is the network of speakers in which each speaker is connected to one or more conversational partner, and this network is then used to model the speakers better. To test whether our model generates more appropriate conversation responses, we build a new conversation corpus containing approximately 27,000 speakers and 770,000 conversations. With this corpus, we run experiments of generating conversational responses and compare our model with other state-of-the-art models. By automatic evaluation metrics and human evaluation, we show that our model outperforms other models in generating appropriate responses. An additional advantage of our model is that it generates better responses for various new user scenarios, for example when one of the speakers is a known user in our corpus but the partner is a new user.

yuan-2006-language | https://aclanthology.org/Y06-1056 | Language Model Based on Word Clustering | Category-based statistic language model is an important method to solve the problem of sparse data. But there are two bottlenecks about this model: (1) the problem of word clustering, it is hard to find a suitable clustering method that has good performance and not large amount of computation. (2) class-based method always loses some prediction ability to adapt the text of different domain. The authors try to solve above problems in this paper. This paper presents a definition of word similarity by utilizing mutual information. Based on word similarity, this paper gives the definition of word set similarity. Experiments show that word clustering algorithm based on similarity is better than conventional greedy clustering method in speed and performance.

A very limited number of user-defined examples are used to bootstrap learning.

ishiwatari-etal-2019-learning | https://aclanthology.org/N19-1350 | Learning to Describe Unknown Phrases with Local and Global Contexts | When reading a text, it is common to become stuck on unfamiliar words and phrases, such as polysemous words with novel senses, rarely used idioms, internet slang, or emerging entities. If we humans cannot figure out the meaning of those expressions from the immediate local context, we consult dictionaries for definitions or search documents or the web to find other global context to help in interpretation. Can machines help us do this work? Which type of context is more important for machines to solve the problem? To answer these questions, we undertake a task of describing a given phrase in natural language based on its local and global contexts. To solve this task, we propose a neural description model that consists of two context encoders and a description decoder. In contrast to the existing methods for non-standard English explanation (Ni and Wang, 2017) and definition generation (Noraset et al., 2017; Gadetsky et al., 2018), our model appropriately takes important clues from both local and global contexts.

Having access to the corresponding explicit or implicit translation relations between such entries might be of great interest for many NLP-based applications. By using Semantic Web-based techniques, translations can be available on the Web to be consumed by other (semantic enabled) resources in a direct manner, not relying on application-specific formats. To that end, in this paper we propose a model for representing translations as linked data, as an extension of the lemon model. Our translation module represents some core information associated to term translations and does not commit to specific views or translation theories. As a proof of concept, we have extracted the translations of the terms contained in Terminesp, a multilingual terminological database, and represented them as linked data.
