Opinion-Aware Retrieval Models Based on Sentiment and Intensity of Lexical Features

Mohammad Bahrani, Thomas Roelleke
2021 International Conference on Modern Management based on Big Data  
The contribution of this paper is a framework for quantifying term frequency (TF) variants with sentiments.  ...  Sentiment analysis has received much attention in Information Retrieval (IR) and other domains including data mining, machine learning algorithms and NLP.  ...  These models are built upon VADER scores. Based on the VADER lexicon, a lexical feature could have a score between +1 and -1.  ...

Tacit Knowledge: Some Suggestions for Operationalization

Veronique Ambrosini, Cliff Bowman
2001 Journal of Management Studies  
A methodology (based on causal mapping, self-Q and storytelling) for empirically researching the subject is outlined.  ...  However, there is little empirical research to support this theoretical proposition. Tacit knowledge has so far resisted operationalization.  ...  term "know-how" ' (p. 98).  ...

StalemateBreaker: A Proactive Content-Introducing Approach to Automatic Human-Computer Conversation [article]

Xiang Li, Lili Mou, Rui Yan, Ming Zhang
2016 arXiv   pre-print
Existing open-domain human-computer conversation systems are typically passive: they either synthesize or retrieve a reply provided a human-issued utterance.  ...  We design a pipeline to determine when, what, and how to introduce new content during human-computer conversation.  ...  In this way, our system is well aware of when, what, and how to proactively introduce new context in a continuous human-computer conversation.  ...

Overcoming Challenges of Applying Reinforcement Learning for Intelligent Vehicle Control

Rafael Pina, Haileleol Tibebu, Joosep Hook, Varuna De Silva, Ahmet Kondoz
2021 Sensors  
Secondly, we discuss a method of transferring RL policies from simulation to reality in order to make the agent experience situations in simulation, so it knows how to react to them in reality.  ...  Reinforcement learning (RL) is a booming area in artificial intelligence.  ...  This way new knowledge is built on something they already know, minimising the amount of new material needed to learn.  ...

Using Multiple Clause Constructors in Inductive Logic Programming for Semantic Parsing [chapter]

Lappoon R. Tang, Raymond J. Mooney
2001 Lecture Notes in Computer Science  
Such a learning approach may be useful when the performance of the task depends on solving a large amount of classification problems and each has its own characteristics which may or may not fit a particular  ...  The task of semantic parser acquisition in two different domains was attempted and preliminary results demonstrated that such an approach is promising.  ...  The only exceptions of which we are aware are a statistical approach to mapping airline-information queries into SQL presented in [10] , a probabilistic decision-tree method for the same task described  ...

Domains and context: First steps towards managing diversity in knowledge

Fausto Giunchiglia, Vincenzo Maltese, Biswanath Dutta
2012 Journal of Web Semantics  
Our work is based on two key ideas. The first is that of using domains, i.e. a general semantic-aware methodology and technique for structuring the background knowledge.  ...  Dealing with this problem has turned out to be a very difficult task because on the one hand the background knowledge should be very large and virtually unbound and, on the other hand, it should be context  ...  Each F NL : S NL → {C  E  Qq} is a mapping function that for each synset s  S NL in a natural language NL assigns an element in C  E  Qq.  ...

Competency-Aware Neural Machine Translation: Can Machine Translation Know its Own Translation Quality? [article]

Pei Zhang, Baosong Yang, Haoran Wei, Dayiheng Liu, Kai Fan, Luo Si, Jun Xie
2022 arXiv   pre-print
Experimental results on four translation tasks demonstrate that the proposed method not only carries out translation tasks intact but also delivers outstanding performance on quality estimation.  ...  To fill this gap, we propose a novel competency-aware NMT by extending conventional NMT with a self-estimator, offering abilities to translate a source sentence and estimate its competency.  ...  On the contrary, our method performs better across out-of-domain tests due to its competency awareness. Even if the domain has not been learned by CANMT, it still knows its incapability.  ...

Thereafter, we develop a probabilistic model for suggesting the suitable treatments or procedures for a particular disease or health condition.  ...  For a blog classified with positive sentiment, we retrieve the top-n similar posts.  ...  The medical domain itself is sensitive to misinformation. Thus, any system built on this data would also have to incorporate relevant domain knowledge.  ...

Tolgahan Cakaloglu, Xiaowei Xu
2019 arXiv   pre-print
The empirical study shows that MRNN with the duplex attention is significantly superior to existing models used for ad-hoc retrieval on benchmark datasets including SQuAD, WikiQA, QUASAR, and TrecQA.  ...  It requires a good understanding of the query and all the documents in a corpus, which is difficult because the meaning of natural language texts depends on the context, syntax,and semantics.  ...  DrQA [13] is built on top of two component; a Document Retriever and a Document Reader respectively. The Document Retriever is a TF-IDF [2] retrieval system built upon Wikipedia corpus.  ...
