Evolutionary fine-tuning of automated semantic annotation systems

John Cuzzola, Jelena Jovanović, Ebrahim Bagheri, Dragan Gašević
2015 Expert systems with applications  
However, the configuration of semantic annotators is presently a tedious and time consuming task as it is primarily based on a manual trialanderror process.  ...  We describe the core fitness functions of PTA that operate on the quality of the annotations produced, and offer a solution, based on a genetic algorithm, for searching the space of possible parameter  ...  such as text search and retrieval systems, various contentbased recommender systems, systems that rely on semantics of textual content to support personal or business decision making and the like.  ...

Optimizing real-time RDF data streams [article]

Joshua Shinavier
2010 arXiv   pre-print
While there exist numerous protocols and data formats for exchanging dynamic RDF data, or RDF updates, these options should be examined carefully in order to enable a Semantic Web equivalent of the high-throughput  ...  This paper contains a brief survey of RDF update formats and a high-level discussion of both TCP and UDP-based transport protocols for updates.  ...  Special thanks go to Jans Aasman and Marko A.

WSIM: Detecting Clone Pages Based on 3-Levels of Similarity Clues

Woosung Jung, Chisu Wu, Eunjoo Lee
2010 2010 IEEE/ACIS 9th International Conference on Computer and Information Science  
In this paper, WSIM has been suggested to measure similarity in web applications, based on the usage degree of clues and two linking directions.  ...  The similarity measure is one of the principal criteria in these approaches. Existing studies on web similarity focused on semantic or context similarity.  ...  Those similarity metrics are commonly based on the link structure, and their purpose is to find semantically similar web pages to the 'query page'.  ...

Cross-lingual Semantic Parsing [article]

Sheng Zhang, Kevin Duh, Benjamin Van Durme
2018 arXiv   pre-print
We introduce the task of cross-lingual semantic parsing: mapping content provided in a source language into a meaning representation based on a target language.  ...  We present: (1) a meaning representation designed to allow systems to target varying levels of structural complexity (shallow to deep analysis), (2) an evaluation metric to measure the similarity between  ...  We design an evaluation metric S (φ,ψ) that computes the similarity between two graph representations as shown Fig. 2(b) . φ is the function to score the similarity between two instances, and ψ scores  ...

A Survey of Model Comparison Approaches and Applications

Matthew Stephan, James R. Cordy
2013 Proceedings of the 1st International Conference on Model-Driven Engineering and Software Development  
We find that many of the latest model comparison techniques are geared towards facilitating arbitrary meta models and use similarity-based matching.  ...  Recently, however, work on comparison for versioning has begun to stagnate, giving way to other applications.  ...  Similarly to UMLDiff, it uses similarity-based metrics.  ...

Extracting query facets from search results

Weize Kong, James Allan
2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
To assist information finding for such faceted queries, we explore a technique that explicitly represents interesting facets of a query using groups of semantically related terms extracted from search  ...  We name these groups query facets and the terms in these groups facet terms. We develop a supervised approach based on a graphical model to recognize query facets from the noisy candidates found.  ...  In this paper, we apply pattern-based semantic class extraction on the top-ranked Web documents to extract candidates for finding query facets.  ...
