  Lee, Y.-Y. ; Ke, H. ; Yen, T.-Y. ; Huang, H.-H. ; Chen, H.-H.: Combining and learning word embedding with WordNet for semantic relatedness and similarity measurement.
  In: Journal of the Association for Information Science and Technology. 71(2020) no.6, S.657-670.
  
  Abstract: In this research, we propose 3 different approaches to measure the semantic relatedness between 2 words: (i) boost the performance of GloVe word embedding model via removing or transforming abnormal dimensions; (ii) linearly combine the information extracted from WordNet and word embeddings; and (iii) utilize word embedding and 12 linguistic information extracted from WordNet as features for Support Vector Regression. We conducted our experiments on 8 benchmark data sets, and computed Spearman correlations between the outputs of our methods and the ground truth. We report our results together with 3 state-of-the-art approaches. The experimental results show that our method can outperform state-of-the-art approaches in all the selected English benchmark data sets.

  Abstract: Because procedures for establishing facets tend toward subjectivity, this pilot project investigates whether the facet structure of a subject literature can be discerned automatically on the basis of its own metadata. Nouns found in the titles of works retrieved from the WorldCat bibliographic database based on Dewey number are mapped against the nodes of the WordNet noun network. Density measures are computed for these nodes to identify nodes best summarizing the title noun data / best corresponding to facets of the subject. Results of the work to date are promising enough to warrant further investigation.

  Pal, D. ; Mitra, M. ; Datta, K.: Improving query expansion using WordNet.
  In: Journal of the Association for Information Science and Technology. 65(2014) no.12, S.2469-2478.
  
  Abstract: This study proposes a new way of using WordNet for query expansion (QE). We choose candidate expansion terms from a set of pseudo-relevant documents; however, the usefulness of these terms is measured based on their definitions provided in a hand-crafted lexical resource such as WordNet. Experiments with a number of standard TREC collections WordNet-based that this method outperforms existing WordNet-based methods. It also compares favorably with established QE methods such as KLD and RM3. Leveraging earlier work in which a combination of QE methods was found to outperform each individual method (as well as other well-known QE methods), we next propose a combination-based QE method that takes into account three different aspects of a candidate expansion term's usefulness: (a) its distribution in the pseudo-relevant documents and in the target corpus, (b) its statistical association with query terms, and (c) its semantic relation with the query, as determined by the overlap between the WordNet definitions of the term and query terms. This combination of diverse sources of information appears to work well on a number of test collections, viz., TREC123, TREC5, TREC678, TREC robust (new), and TREC910 collections, and yields significant improvements over competing methods on most of these collections.

  In: http://arxiv.org/find/all/1/all:+EXACT+semantic_interoperability/0/1/0/all/0/1. [arXiv:1105.1406].
  
  Abstract: Information exchange among many sources in Internet is more autonomous, dynamic and free. The situation drive difference view of concepts among sources. For example, word 'bank' has meaning as economic institution for economy domain, but for ecology domain it will be defined as slope of river or lake. In this paper, we will evaluate latent semantic and WordNet approach to calculate semantic similarity. The evaluation will be run for some concepts from different domain with reference by expert or human. Result of the evaluation can provide a contribution for mapping of concept, query rewriting, interoperability, etc.

  Assem, M. van: Converting and integrating vocabularies for the Semantic Web.

  Abstract: This thesis focuses on conversion of vocabularies for representation and integration of collections on the Semantic Web. A secondary focus is how to represent metadata schemas (RDF Schemas representing metadata element sets) such that they interoperate with vocabularies. The primary domain in which we operate is that of cultural heritage collections. The background worldview in which a solution is sought is that of the Semantic Web research paradigmwith its associated theories, methods, tools and use cases. In other words, we assume the SemanticWeb is in principle able to provide the context to realize interoperable collections. Interoperability is dependent on the interplay between representations and the applications that use them. We mean applications in the widest sense, such as "search" and "annotation". These applications or tasks are often present in software applications, such as the E-Culture application. It is therefore necessary that applications requirements on the vocabulary representation are met. This leads us to formulate the following problem statement: HOW CAN EXISTING VOCABULARIES BE MADE AVAILABLE TO SEMANTIC WEB APPLICATIONS? ; We refine the problem statement into three research questions. The first two focus on the problem of conversion of a vocabulary to a Semantic Web representation from its original format. Conversion of a vocabulary to a representation in a Semantic Web language is necessary to make the vocabulary available to SemanticWeb applications. In the last question we focus on integration of collection metadata schemas in a way that allows for vocabulary representations as produced by our methods.

  Abstract: WordNet, a lexical database for English, is organized around semantic and lexical relationships between synsets, concepts represented by sets of synonymous word senses. Offering reasonably comprehensive coverage of the nouns, verbs, adjectives, and adverbs of general English, WordNet is a widely used resource for dealing with the ambiguity that arises from homonymy, polysemy, and synonymy. WordNet is used in many information-related tasks and applications (e.g., word sense disambiguation, semantic similarity, lexical chaining, alignment of parallel corpora, text segmentation, sentiment and subjectivity analysis, text classification, information retrieval, text summarization, question answering, information extraction, and machine translation).

  Suchanek, F.M. ; Kasneci, G. ; Weikum, G.: YAGO: a large ontology from Wikipedia and WordNet.
  In: Web semantics: science, services and agents on the World Wide Web. 6(2008) no.3, S.203-217.
  
  Abstract: This article presents YAGO, a large ontology with high coverage and precision. YAGO has been automatically derived from Wikipedia and WordNet. It comprises entities and relations, and currently contains more than 1.7 million entities and 15 million facts. These include the taxonomic Is-A hierarchy as well as semantic relations between entities. The facts for YAGO have been extracted from the category system and the infoboxes of Wikipedia and have been combined with taxonomic relations from WordNet. Type checking techniques help us keep YAGO's precision at 95%-as proven by an extensive evaluation study. YAGO is based on a clean logical model with a decidable consistency. Furthermore, it allows representing n-ary relations in a natural way while maintaining compatibility with RDFS. A powerful query model facilitates access to YAGO's data.

  Suchanek, F.M. ; Kasneci, G. ; Weikum, G.: YAGO: a core of semantic knowledge unifying WordNet and Wikipedia.
  In: http://www2007.org/papers/paper391.pdf.
  
  Abstract: We present YAGO, a light-weight and extensible ontology with high coverage and quality. YAGO builds on entities and relations and currently contains more than 1 million entities and 5 million facts. This includes the Is-A hierarchy as well as non-taxonomic relations between entities (such as hasWonPrize). The facts have been automatically extracted from Wikipedia and unified with WordNet, using a carefully designed combination of rule-based and heuristic methods described in this paper. The resulting knowledge base is a major step beyond WordNet: in quality by adding knowledge about individuals like persons, organizations, products, etc. with their semantic relationships - and in quantity by increasing the number of facts by more than an order of magnitude. Our empirical evaluation of fact correctness shows an accuracy of about 95%. YAGO is based on a logically clean model, which is decidable, extensible, and compatible with RDFS. Finally, we show how YAGO can be further extended by state-of-the-art information extraction techniques.

  Abstract: Semantic types provide a level of abstraction over particulars with shared behavior, such as in the participant structure of semantic frames. The paper presents a preliminary investigation, drawing on data from WordNet and FrameNet, into the relationship between hierarchical level and the semantic types that name frame elements (a.k.a. slots). Patterns discovered include: (1) The level of abstraction of a frame is generally matched by the level of abstraction of its frame elements. (2) The roles played by persons tend to be expressed very specifically. (3) Frame elements that mirror the name of the frame tend to be expressed specifically. (4) Some frame participants tend to be expressed at a constant (general) level of abstraction, regardless of the level of abstraction of the overall frame.

  Abstract: This paper describes work in progress to identify automated methods to complement and streamline the intellectual process in the generation of faceted schemes. It reports on the development of the word pair heuristic, the suffix heuristic, and the WordNet heuristic, and how the three heuristics integrate to produce an initial organization of terms from which a classificationist can more efficiently construct a faceted vocabulary.

  Abstract: Interface designs for lexical databases in NLP have suffered from not following design principles developed in the information visualization research community. We present a design paradigm and show it can be used to generate visualizations which maximize the usability and utility ofWordNet. The techniques can be generally applied to other lexical databases used in NLP research.

  Assem, M. van ; Gangemi, A. ; Schreiber, G.: Conversion of WordNet to a standard RDF/OWL representation.
  In: http://www.cs.vu.nl/~mark/papers/Assem06a.pdf.
  
  Abstract: This paper presents an overview of the work in progress at the W3C to produce a standard conversion of WordNet to the RDF/OWL representation language in use in the SemanticWeb community. Such a standard representation is useful to provide application developers a high-quality resource and to promote interoperability. Important requirements in this conversion process are that it should be complete and should stay close to WordNet's conceptual model. The paper explains the steps taken to produce the conversion and details design decisions such as the composition of the class hierarchy and properties, the addition of suitable OWL semantics and the chosen format of the URIs. Additional topics include a strategy to incorporate OWL and RDFS semantics in one schema such that both RDF(S) infrastructure and OWL infrastructure can interpret the information correctly, problems encountered in understanding the Prolog source files and the description of the two versions that are provided (Basic and Full) to accommodate different usages of WordNet.

  Abstract: This paper describes a method for converting existing thesauri and related resources from their native format to RDF(S) and OWL. The method identifies four steps in the conversion process. In each step, decisions have to be taken with respect to the syntax or semantics of the resulting representation. Each step is supported through a number of guidelines. The method is illustrated through conversions of two large thesauri: MeSH and WordNet.

  Abstract: 1. Introduction In this age of world wide communication, and the resulting thrust towards universality, the domain specific specialized vocabularies used in the visual resources and bibliographic databases pose limitations of access. Although they provide adequate access to the experts in the field, a layperson with little or no knowledge in the field (lay user) is constrained by the terminology. The meaning of the index terms used in the databases or the choice of search terms is not easy for such a user. It presupposes the ability of the users to demarcate and discriminate a concept/entity from other entities, and a lay user is often unclear about the connotations of the terms, and the subtle differences in their usage within the domain. The challenge to any indexer of visual resources is the subjective nature of the interpretation of the image itself. Images very seldom contain any textual information besides title, creator or date. However, images also need to be accessed for content and context as well, and context and content description are very often left to "the eye of the beholder." Utilizing standardized terminology can help classify and define an image more accurately, thereby improving accessibility. However, the special needs of a lay user still remain to be addressed. The use of as an auxiliary resource may help alleviate this problem to some extent. This paper presents the findings of an exploratory study to assess the value of WordNet as a pre-search tool to aid in the understanding and the identification of concepts, including the terminology needed to search visual resources databases in the field of architecture. It also reveals the nature of the problems encountered by lay users and how specific aspects of WordNet were helpful. WordNet is an electronic lexical database based an psycho-linguistic theories of human lexical memory, developed and maintained at Princeton University since 1985. Sets of synonymous terms (or synsets) constitute its basic organization. English nouns, verbs, an adjectives are organized into synsets, each representing one underlying lexical concept. Several types of relationships between the synsets are recorded in Wordnet.

  Abstract: WordNet, an electronic lexical database, is considerd to be the most important resource available to researchers in computational linguistics, text analysis, and many related areas. English nouns, verbs, adjectives, and adverbs are organized into synonym sets, each representing one underlying lexicalized concept. Different relations link the synonym sets. The purpose of this volume is twofold. First, it discusses the design of WordNet and the theoretical motivation behind it. Second, it provides a survey of representative applications, including word sense identification, information retrieval, selectional preferences of verbs, and lexical chains
