Semantic parsing using LSTM encoder-decoder neural networks have become promising approach. However, human automated translation of natural language does not provide grammaticality guarantees for the sentences generate such a guarantee is particularly important for practical cases where a data base query can cause critical errors if the sentence is ungrammatical. In this work, we propose an neural architecture called Encoder CFG-Decoder, whose output conforms to a given context-free grammar. Results are show for any implementation of such architecture display its correctness and providing benchmark accuracy levels better than the literature. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1807.07108v1-abstract-full').style.display = 'none'; document.getElementById('1807.07108v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 18 July, 2018; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2018. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1803.04329">arXiv:1803.04329</a> <span> [<a href="https://arxiv.org/pdf/1803.04329">pdf</a>, <a href="https://arxiv.org/format/1803.04329">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Computation and Language">cs.CL</span> </div> </div> <p class="title is-5 mathjax"> Semantic Parsing Natural Language into SPARQL: Improving Target Language Representation with Neural Attention </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cs?searchtype=author&query=Luz%2C+F+F">Fabiano Ferreira Luz</a>, <a href="/search/cs?searchtype=author&query=Finger%2C+M">Marcelo Finger</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="1803.04329v1-abstract-short" style="display: inline;"> Semantic parsing is the process of mapping a natural language sentence into a formal representation of its meaning.

In this work we use the neural network approach to transform natural language sentence into a query to an ontology database in the SPARQL language. This method does not rely on handcraft-rules, high-quality lexicons, manually-built templates or other handmade complex structures. Our approach is based on vector space model and neural networks. The proposed model is based in two learning steps. The first step generates a vector representation for the sentence in natural language and SPARQL query. The second step uses this vector representation as input to a neural network (LSTM with attention mechanism) to generate a model able to encode natural language and decode SPARQL. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1803.04329v1-abstract-full').style.display = 'none';
