Quantify query ambiguity using ODP metadata

Guang Qiu, Kangmiao Liu, Jiajun Bu, Chun Chen, Zhiming Kang
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
In this poster, we propose such a measure using query topics based on the topic structure selected from the Open Directory Project (ODP) taxonomy.  ...  As there is already lots of work done on resolving ambiguity, vague queries could be handled using corresponding approaches separately if they can be identified in advance.  ...  Specifically, we use clarity score to quantify the lack of ambiguity i.e. the larger the clarity score of a query holds, the less ambiguous the query is.  ...

Estimating query performance using class predictions

Kevyn Collins-Thompson, Paul N. Bennett
2009 Proceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '09  
We investigate using topic prediction data, as a summary of document content, to compute measures of search result quality.  ...  Our findings suggest that using class predictions can offer comparable performance to full language models while reducing computation overhead.  ...  A variety of other work has examined query classification and use of class labels. Recently [8] quantified query ambiguity using ODP metadata for individual query terms.  ...

Open Data and the Status Quo – A Fine-Grained Evaluation Framework for Open Data Quality and an Analysis of Open Data portals in Germany [article]

Lisa Wenige, Claus Stadler, Michael Martin, Richard Figura, Robert Sauter, Christopher W. Frank
2021 arXiv   pre-print
This paper presents a framework for assessing data and metadata quality within Open Data portals.  ...  We have validated our novel quality framework for the German Open Data landscape and found out that metadata often still lacks meaningful descriptions and is not yet extensively connected to the Semantic  ...  The DCAT metadata descriptions serve as the foundation of our use case analysis and are publicly available on Github in turtle format and can thus be queried with a SPARQL-enabled database. 7 can be  ...

Ontology-Based Information Behaviour to Improve Web Search

Silvia Calegari, Gabriella Pasi
2010 Future Internet  
Personalized ontologies are used to improve the quality of Web search by applying two main techniques: query reformulation and re-ranking of query evaluation results.  ...  In this paper we analyze various methodologies presented in the literature aimed at using personalized ontologies, defined on the basis of the observation of Information Behaviour to help the user in finding  ...  By using the ODP, good results are obtained for the following types of user's queries: relatively ambiguous query and ambiguous query.  ...

Predicting Query Performance via Classification [chapter]

Kevyn Collins-Thompson, Paul N. Bennett
2010 Lecture Notes in Computer Science  
We investigate using topic prediction data, as a summary of document content, to compute measures of search result quality.  ...  Our findings suggest that using class predictions can offer comparable performance to full language models while reducing computation overhead.  ...  Recently [16] quantified query ambiguity using ODP metadata for individual query terms, and [18] examined the category spread of top-ranked documents to identify ambiguous queries.  ...

Ontologies for Software Engineering: Past, Present and Future

M. P. S. Bhatia, Akshi Kumar, Rohit Beniwal
2016 Indian Journal of Science and Technology  
Prolifically published studies have further substantiated the benefits of ontologies to the field of Software Engineering, which clearly motivate us to explore further opportunities available in this collaborated  ...  For this purpose, they encoded the metadata information in RDF graph and SPARQL queries were used over them in order to facilitate the understanding and maintenance of the software component.  ...  Patterns (ODPs).  ...

Current Approaches to Search Result Diversification

Enrico Minack, Gianluca Demartini, Wolfgang Nejdl
2009 International Semantic Web Conference  
In [3] , the authors use 10,000 queries and top 50 retrieved results from a commercial search engine, judgements obtained with the Amazon Mechanical Turk 1 , and the Open Directory Project (ODP) 2 taxonomy  ...  The authors dene functions that quantify novel information a new result conveys additionally to an (the) existing result(s) using the KL-divergence.  ...

Multiple perspective interactive search: a paradigm for exploratory search and information retrieval on the web

Rahul Singh, Ya-Wen Hsu, Naureen Moon
2011 Multimedia tools and applications  
In the proposed paradigm, hits obtained from executing a query are first analyzed to determine latent content-based correlations between the pages.  ...  This information is used to organize and present the results through an interactive and reflective user interface which supports both exploration and search.  ...  This experiment was designed to quantify the advantages (if any) due to the ODP-driven clustering.  ...

A Review of Geospatial Semantic Information Modeling and Elicitation Approaches

Margarita Kokla, Eric Guilbert
2020 ISPRS International Journal of Geo-Information  
These processes focus on eliciting a structured representation of information in various forms such as: semantic metadata, links to ontology concepts, a collection of topics, etc.  ...  The first topic deals with the development of ontologies at different levels of generality and formality, tailored to various needs and uses.  ...  Multilingual thesauri and ontologies are used to enrich metadata with synonyms and term translations, as well as query terms for improving metadata discovery [156] .  ...

Algorithmic detection of semantic similarity

Ana G. Maguitman, Filippo Menczer, Heather Roinestad, Alessandro Vespignani
2005 Proceedings of the 14th international conference on World Wide Web - WWW '05  
Surprisingly, the traditional use of text similarity turns out to be ineffective for relevance ranking.  ...  Here we propose to leverage human-generated metadata -namely topical directories -to measure semantic relationships among massive numbers of pairs of Web pages or topics.  ...  We can generalize the sliding ratio in the following ways: σ c σ ℓ σ c H(σ ℓ ) σ ℓ 0.2 σ c + 0.8 σ ℓ 0.8 σ c + 0.2 σ ℓ σ c • use a page as a target rather than an arbitrary query, as is done in "query  ...
