Convolutional Neural Network Architectures for Matching Natural Language Sentences
TLDR
Convolutional neural network models for matching two sentences are proposed, by adapting the convolutional strategy in vision and speech and nicely represent the hierarchical structures of sentences with their layer-by-layer composition and pooling.
Incorporating Copying Mechanism in Sequence-to-Sequence Learning
TLDR
This paper incorporates copying into neural network-based Seq2Seq learning and proposes a new model called CopyNet with encoder-decoder structure which can nicely integrate the regular way of word generation in the decoder with the new copying mechanism which can choose sub-sequences in the input sequence and put them at proper places in the output sequence.
AdaRank: a boosting algorithm for information retrieval
TLDR
The proposed novel learning algorithm, referred to as AdaRank, repeatedly constructs 'weak rankers' on the basis of reweighted training data and finally linearly combines the weak rankers for making ranking predictions, which proves that the training process of AdaRank is exactly that of enhancing the performance measure used.
Neural Responding Machine for Short-Text Conversation
TLDR
Empirical study shows that NRM can generate grammatically correct and content-wise appropriate responses to over 75% of the input text, outperforming state-of-the-arts in the same setting, including retrieval-based and SMT-based models.
LETOR: A benchmark collection for research on learning to rank for information retrieval
TLDR
The details of the LETOR collection are described and it is shown how it can be used in different kinds of researches, and several state-of-the-art learning to rank algorithms on LETOR are compared.
Modeling Coverage for Neural Machine Translation
TLDR
This paper proposes coverage-based NMT, which maintains a coverage vector to keep track of the attention history and improves both translation quality and alignment quality over standard attention- based NMT.
Adapting ranking SVM to document retrieval
TLDR
Experimental results show that the modifications made in conventional Ranking SVM can outperform the conventional ranking SVM and other existing methods for document retrieval on two datasets and employ two methods to conduct optimization on the loss function: gradient descent and quadratic programming.
Context-aware query suggestion by mining click-through and session data
TLDR
This paper proposes a novel context-aware query suggestion approach which is in two steps, and outperforms two baseline methods in both coverage and quality of suggestions.
Global Ranking Using Continuous Conditional Random Fields
TLDR
The paper shows how the Continuous CRF method can perform global ranking better than baselines and can naturally represent the content information of objects as well as the relation information between objects, necessary for global ranking.
