A structural approach to the automatic adjudication of word sense disagreements

2008 Natural Language Engineering  
The semantic annotation of texts with senses from a computational lexicon is a complex and often subjective task.  ...  We perform a twofold experimental evaluation of the approach applied to manual annotations from the SemCor corpus, and automatic annotations from the Senseval-3 English all-words competition.  ...  We wish to thank Francesco Maria Tucci, Giuliana and Maria Luisa Pesaresi, and Orin Hargraves for their invaluable support.  ...

Knowledge-based interaction in software development

Dimitris Panagiotou, Fotis Paraskevopoulos, Gregoris Mentzas
2011 International Journal of Intelligent Decision Technologies  
Building a knowledge base with software artefacts by using the KnowBench system can then be exploited by semantic search engines or P2P metadata infrastructures in order to foster the dissemination of  ...  However, current software development environments are "syntactic", i.e. they do not facilitate understanding the semantics of software artefacts and hence cannot fully support the knowledge-driven activities  ...  -Zooming in/out the whole graph. Manual semantic annotation of source code An important aspect of the KnowBench is the ability to annotate semantically source code.  ...

Scalable Semantic Annotation of Text Using Lexical and Web Resources [chapter]

Elias Zavitsanos, George Tsatsaronis, Iraklis Varlamis, Georgios Paliouras
2010 Lecture Notes in Computer Science  
In this paper we are dealing with the task of adding domainspecific semantic tags to a document, based solely on the domain ontology and generic lexical and Web resources.  ...  The method comprises a novel combination of measures of semantic relatedness and word sense disambiguation techniques, in order to identify the most related ontology concepts for the document.  ...  The proposed method consists of a novel combination of measures of semantic relatedness and word sense disambiguation techniques, in order to identify the most related ontology concepts for a given document  ...

Towards a universal wordnet by learning from combined evidence

Gerard de Melo, Gerhard Weikum
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
We propose a methodology for the automatic construction of a large-scale multilingual lexical database where words of many languages are hierarchically organized in terms of their meanings and their semantic  ...  Lexical databases are invaluable sources of knowledge about words and their meanings, with numerous applications in areas like NLP, IR, and AI.  ...  The input graph G0 does not cover any of the validation arcs, and thus has a recall and F1-score of 0%.  ...

Weakly Supervised Word Sense Disambiguation Using Automatically Labelled Collections

Angelina Sergeevna Bolshina, Natalia Valentinovna Loukachevitch
2021 Proceedings of the Institute for System Programming of RAS  
To cope with the knowledge acquisition bottleneck in Russian, we first utilized the method based on the concept of monosemous relatives to automatically generate a labelled training collection.  ...  State-of-the-art supervised word sense disambiguation models require large sense-tagged training sets. However, many low-resource languages, including Russian, lack such a large amount of data.  ...  This research has been supported by the Interdisciplinary Scientific and Educational School of Lomonosov Moscow State University "Brain, Cognitive Systems, Artificial Intelligence".  ...

Unified Partial Configuration Model Framework for Fast Partially Occluded Object Detection in High-Resolution Remote Sensing Images

Shaohua Qiu, Gongjian Wen, Jia Liu, Zhipeng Deng, Yaxiang Fan
2018 Remote Sensing  
Recent partial configuration model (PCM) based methods deal with occlusion yet suffer from the problems of massive manual annotation, separate parameter learning, and low training and detection efficiency  ...  The work in this paper is inspired from the problems in PCM and AFI-PCM, which tries to integrate the entire PCM model with a novel part sharing mechanism for both fast and automatic model training and  ...  The semantic parts are defined manually and semantically, along with the skeleton graph of the category.  ...

Automatic extraction of paraphrastic phrases from small-size corpora

Thierry Poibeau, Dominique Dutoit
2009 Lingvisticæ investigationes  
This knowledge is semi-automatically derived from the text collection, in interaction with a large semantic network.  ...  In order to decrease the time spent on the elaboration of resources for NLP system (for example for Information Extraction), we suggest to use a knowledge acquisition module that helps extracting new information  ...  The process is made of automatic steps and manual validation stages. The process is weakly supervised since the analyst only has to provide one example to the system.  ...
