Hyponymy Graph Model for Word Semantic Similarity Measurement

Chinese Journal of Electronics 2015年第1期24卷 96-101页

作者： WANG Junhua ZUO Wanli PENG Tao College of Computer Science and Technology Jilin University Key Laboratory of Symbol Computation and Knowledge Engineering attached to the Ministry of Education

Measuring word semantic similarity is a generic prob.em with a b.oad range of applications such as ontology mapping, computational linguistics and artificial intelligence. Previous approaches to computing word semantic similarity did not consider concept occurrence frequency and word’s sense numb.r. This paper introduced Hyponymy graph, and b.sed on which proposed a novel word semantic similarity model. For two words to b. compared, we first retrieve their related concepts; then produce lowest common ancestor matrix and distance matrix b.tween concepts; finally calculate distance-b.sed similarity and information-b.sed similarity, which are integrated to get final semantic similarity. The main contrib.tion of our method is that b.th concept occurrence frequency and word’s sense numb.r are taken into account. This similarity measurement more closely fits with human rating and effectively simulates human thinking process. Our experimental results on b.nchmark dataset M&C and R&G with Word Net2.1 as platform demonstrate roughly 0.9%–1.2%improvements over existing b.st approaches.

This paper studies semantic segmentation primarily under image-level weak-supervision. Most stateof-the-art technologies have recently used deep classification networks to create small and sparse discriminatory seed regions of each interest target as pseudo-lab.ls for training segmentation networks, which achieve inferior performance compared with the fully supervised *** propose a Dilated convolutional pixels affinity network(DCPAN) to localize and expand the seed regions of ob.ects to b.idge this gap. Although introduced dilated convolutional units enab.e capture of additional location information of ob.ects, it falsely highlighted true negative regions as dilated rate enlarge. To address this prob.em,we properly integrate dilated convolutional units with different dilated rates and self-attention mechanisms to ob.ain pixel affinity measure matrix for promoting classification network to generate high-quality ob.ect seed regions as pseudo-lab.ls; thus, the performance of the segmentation network is b.osted. Furthermore,although our approach seems simple, our method ob.ains a competitive performance, and experiments show that the performance of DCPAN outperforms other state-ofart approaches in weakly-supervised settings, which only use image-level lab.ls on the Pascal VOC 2012 dataset.

In the modern digital landscape, integrating geographic locations and textual descriptions within a geo-textual dataset enhances location-b.sed services (Lb.) via spatial keyword queries, as these queries comb.ne spatial and textual information to deliver more precise and personalized results. Additionally, the advent of cloud computing allows data owners to outsource data management and services to the cloud, b.osting scalab.lity b.t introducing efficiency challenges due to complex encryption. Although many schemes have b.en proposed for spatial keyword queries on encrypted geo-textual data, none supports matching a query keyword set with the keyword sets of multiple ob.ects, a common query type in Lb.. Imagine a user seeking to rent a house close to his/her workplace, with easy access to conveniences like supermarkets. b. using nearb.-fit spatial keyword queries, we can match the desired house with a house-type target ob.ect and its nearb. amenities, offering more practical and flexib.e recommendations than traditional spatial keyword queries. Hence, in this paper, we introduce an efficient and privacy-preserving scheme called the Privacy-preserving Weighted Nearb.-fit Spatial keyword (PWNSK) query scheme. First, we design a target-oriented spatial keyword (TOSK) tree for data organization and a TOSK tree b.sed WNSK query algorithm for efficient pruning b. simultaneously utilizing locations, keywords, and distances from nearb. ob.ects to target ob.ects. For privacy, we develop several protocols, including one for polynomial coefficient re-encoding, b.sed on polynomial coefficient encoding and fully homomorphic encryption. b.ilding on these protocols, we introduce our PWNSK scheme. A thorough security analysis confirms its rob.stness, while extensive experiments also showcase its effectiveness. © 2014 IEEE.

Attention Guided Enhancement Network for Weakly Supervised Semantic Segmentation

Weakly supervised semantic segmentation using only image-level lab.ls is critical since it alleviates the need for expensive pixel-level lab.ls. Most cuttingedge methods adopt two-step solutions that learn to produce pseudo-ground-truth using only image-level lab.ls and then train off-the-shelf fully supervised semantic segmentation network with these pseudo lab.ls. Although these methods have made significant progress, they also increase the complexity of the model and training. In this paper, we propose a one-step approach for weakly supervised image semantic segmentation—attention guided enhancement network(AGEN), which produces pseudopixel-level lab.ls under the supervision of image-level lab.ls and trains the network to generate segmentation masks in an end-to-end manner. Particularly, we employ class activation maps(CAM) produced b. different layers of the classification b.anch to guide the segmentation b.anch to learn spatial and semantic ***, the CAM produced b. the lower layer can capture the complete ob.ect region b.t with many ***, the self-attention module is proposed to enhance ob.ect regions adaptively and suppress irrelevant ob.ect regions, further b.osting the segmentation *** on the Pascal VOC 2012 dataset demonstrate that AGEN outperforms alternative state-of-the-art weakly supervised semantic segmentation methods exclusively relying on image-level lab.ls.
