Seeding Strategies for Semantic Disambiguation

Annika Hinze, David Bainbridge, Rebekah Wilkins, Craig Taube-Schock, J. Stephen Downie
2018 Proceedings of the 18th ACM/IEEE on Joint Conference on Digital Libraries - JCDL '18  
This paper introduces the seeding algorithm and explores seeding strategies for identifying these initial concepts in text volumes, such as books, that are stored in a digital library.  ...  Semantic disambiguation determines the meaning of words and phrases in a text, for which we use an automatically-generated Concept-in-Context (CiC) network.  ...  SEEDING FOR DISAMBIGUATION The disambiguation process has two phases: seeding and full semantic analysis.  ...

Knowledge Base Unification via Sense Embeddings and Disambiguation

Claudio Delli Bovi, Luis Espinosa Anke, Roberto Navigli
2015 Proceedings of the 2015 Conference on Empirical Methods in Natural Language Processing  
We present KB-UNIFY, a novel approach for integrating the output of different Open Information Extraction systems into a single unified and fully disambiguated knowledge repository.  ...  KB-UNIFY consists of three main steps: (1) disambiguation of relation argument pairs via a sensebased vector representation and a large unified sense inventory; (2) ranking of semantic relations according  ...  We thus devised a disambiguation strategy that comprises three successive steps: 1.  ...

Kanopy: Analysing the Semantic Network around Document Topics [chapter]

Ioana Hulpuş, Conor Hayes, Marcel Karnstedt, Derek Greene, Marek Jozwowicz
2013 Lecture Notes in Computer Science  
Besides the common task of semantic annotation of documents, Kanopy analyses the semantic network that resides in DBpedia around extracted concepts.  ...  The system's main novelty lies in the translation of social network analysis measures to semantic networks in order to find suitable topic labels.  ...  The applied linkage strategy and cut-off point can be adjusted from the user interface. After this stage, we obtain several clusters of noun phrases. Concept linking & disambiguation.  ...

Improving image sets through sense disambiguation and context ranking

Anthony R. Buck, Walterio W. Mayol
2009 2009 IEEE International Conference on Systems, Man and Cybernetics  
We propose that, in extension, improvement can be achieved in relevance, noise-reduction and completeness through sense disambiguation and contextual meta-data prepossessing.  ...  Within the paper we investigate different schemes for keyword set construction; ontology exclusive and authority extended, along with three differing ranking mechanisms.  ...  ACKNOWLEDGMENT The authors would like to thank the EPSRC for there supportive funding of the first authors DTA grant.  ...

WebChild 2.0 : Fine-Grained Commonsense Knowledge Distillation

Niket Tandon, Gerard de Melo, Gerhard Weikum
2017 Proceedings of ACL 2017, System Demonstrations  
Despite important progress in the area of intelligent systems, most such systems still lack commonsense knowledge that appears crucial for enabling smarter, more human-like decisions.  ...  In this paper, we present a system based on a series of algorithms to distill fine-grained disambiguated commonsense knowledge from massive amounts of text.  ...  Our method considers joint semantic role labeling and word sense disambiguation for parsing these scripts to generate candidate items for the activity frames.  ...

Unsupervised Approach to Word Sense Disambiguation in Malayalam

K.P. Sruthi Sankar, P.C. Reghu Raj, V. Jayan
2016 Procedia Technology - Elsevier  
For each possible sense of the ambiguous word, a relatively small set of training examples (seed sets) are identified which represents the sense.  ...  Seed set expansion module extends the seed set by adding most similar words to the seed set elements. These extended sets act as sense clusters.  ...  Bhadran V K, Associate Director, Centre for Development of Advanced Computing, for his sincere directions imparted with the project.  ...

A Resource-Based Method for Named Entity Extraction and Classification [chapter]

Pablo Gamallo, Marcos Garcia
2011 Lecture Notes in Computer Science  
Languageindependent heuristics are used to disambiguate and classify entities that have been already identified (or recognized) in text.  ...  We compare the performance of our resource-based system with that of a supervised NEC module implemented for the FreeLing suite, which was the winner system in CoNLL-2002 competition.  ...  In particular, their extraction strategy requires some lists of seed named entities to generate queries and retrieve Web pages containing occurrences of the seed entities.  ...

2016 arXiv   pre-print
This paper details the implementation of an algorithm for automatically generating a high-level knowledge network to perform commonsense reasoning, specifically with the application of robotic task repair  ...  For example, if a seed word was incorrectly disambiguated, the relations added from ConceptNet would often be related to the incorrect sense of the seed word.  ...  Seed Word Disambiguation After the seed words have been collected, they must be disambiguated to determine the contextually correct senses of the words.  ...
