Leverage Lexical Knowledge for Chinese Named Entity Recognition via Collaborative Graph Network

open access: yesConference on Empirical Methods in Natural Language Processing, 2019
The lack of word boundaries information has been seen as one of the main obstacles to develop a high performance Chinese named entity recognition (NER) system.

Spatial-Temporal Synchronous Graph Convolutional Networks: A New Framework for Spatial-Temporal Network Data Forecasting

open access: yesAAAI Conference on Artificial Intelligence, 2020
Spatial-temporal network data forecasting is of great importance in a huge amount of applications for traffic management and urban planning. However, the underlying complex spatial-temporal correlations and heterogeneities make this problem challenging ...

Predicting traffic propagation flow in urban road network with multi-graph convolutional network

open access: yesComplex & Intelligent Systems, 2023
Traffic volume propagating from upstream road link to downstream road link is the key parameter for designing intersection signal timing scheme. Recent works successfully used graph convolutional network (GCN) and specific time-series model to forecast ...

New Turan-type bounds for Johnson graphs [PDF]

open access: yesarXiv, 2021
In this paper, we consider the Johnson's graphs. We study the extremal properties of the Johnson's graphs. Namely, we investigate the number of edges in an arbitrary subgraph of this graph. Namely, in this article we prove analogs of Turan's 1941 theorem.

Named entity disambiguation in short texts over knowledge graphs [PDF]

open access: yesKnowledge and Information Systems, 2022
The ever-growing usage of knowledge graphs (KGs) positions named entity disambiguation (NED) at the heart of designing accurate KG-driven systems such as query answering systems (QAS). According to the current research, most studies dealing with NED on KGs involve long texts, which is not the case of short text fragments, identified by their limited ...

On the Sombor index and Sombor energy of m-splitting graph and m-shadow graph of regular graphs [PDF]

open access: yesarXiv, 2022
A vertex-degree-based topological index named as Sombor index of a simple graph G with n vertices was recently introduced by I. Gutman. In this paper, we find Sombor index of m-splitting graph and m-shadow graph. Also, we determine relation between energy and Sombor energy of m-splitting graph and m-shadow graph of k-regular graph.

Name disambiguation from link data in a collaboration graph [PDF]

open access: yes2014 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM 2014), 2014
The entity disambiguation task partitions the records belonging to multiple persons with the objective that each decomposed partition is composed of records of a unique person. Existing solutions to this task use either biographical attributes, or auxiliary features that are collected from external sources, such as Wikipedia.

Using graph distances for named-entity linking

open access: yesScience of Computer Programming, 2016
We formalize entity linking as an optimization problem.The problem is NP-hard but solvable in linear time under restrictive assumptions.We propose heuristics enforcing the assumptions or optimizing similar objectives.We show how our approaches perform w.r.t. some baselines on real data. Entity-linking is a natural-language-processing task that consists
