Building knowledge maps of Web graphs

Valeria Fionda, Claudio Gutierrez, Giuseppe Pirrò
2016 Artificial Intelligence  
We research the problem of building knowledge maps of graph-like information. There exist well-consolidated cartographic principles and techniques for mapping physical landscapes.  ...  We present an implementation of our formalism on the Web of Linked Data graph and discuss algorithms that efficiently generate and combine (via an algebra) regions and maps.  ...  Organization of the paper The paper starts with a general overview of the problem of building Web maps and continues with a formal framework to construct maps of a graph (Section 3).  ...

Building and Using a Knowledge Graph to Combat Human Trafficking [chapter]

Pedro Szekely, Craig A. Knoblock, Jason Slepicka, Andrew Philpot, Amandeep Singh, Chengye Yin, Dipsy Kapoor, Prem Natarajan, Daniel Marcu, Kevin Knight, David Stallard, Subessware S. Karunamoorthy (+11 others)
2015 Lecture Notes in Computer Science  
There is a huge amount of data spread across the web and stored in databases that we can use to build knowledge graphs.  ...  However, exploiting this data to build knowledge graphs is difficult due to the heterogeneity of the sources, scale of the amount of data, and noise in the data.  ...  Building Knowledge Graphs In this section we describe our overall approach to building knowledge graphs.  ...

A_knowledge_graph_is_more_than_just_a_graph_database

Charles Ivie, Ora Lassila
2021 Zenodo  
Acknowledging that a "knowledge graph system" is really a platform on top of which many applications (i.e., use cases) are implemented, access interfaces and abstractions are of paramount importance  ...  customers as well as our long history in building knowledge graph and Semantic Web software Graph databases Graph storage is needed for most knowledge graph projects Since one seldom uses just a graph  ...  the challenge, however To actually build a knowledge graph system, you need many other tools as well • (and you may also need to write some code of your own…) This talk reflects our experiences helping  ...

Web service approaches for providing enriched data structures to generalisation operators

Moritz Neun, Dirk Burghardt, Robert Weibel
2008 International Journal of Geographical Information Science  
On the other hand there exist various hierarchical and non-hierarchical relationships between map features, many of which can be represented by graph data structures.  ...  On the one hand the structural knowledge can be expressed by enriching map features with additional geometries or attributes.  ...  Web service approaches  ...

RECONCILING CITY MODELS WITH BIM IN KNOWLEDGE GRAPHS: A FEASIBILITY STUDY OF DATA INTEGRATION FOR SOLAR ENERGY SIMULATION

W. Huang, P.-O. Olsson, J. Kanters, L. Harrie
2020 ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
We also investigate an alternative avenue, namely a semantic web approach, in which both the BIM and city models are transformed into knowledge graphs (linked data).  ...  This paper compares different paths of such integrative data retrieval, as well as discloses the gaps mainly with the semantic web approach to further unlock its potential.  ...  CONCLUDING REMARKS In this paper, we demonstrate the feasibility of using knowledge graphs (semantic web technologies) for parts of the GeoBIM data integration.  ...

Sutanay Choudhury, Khushbu Agarwal, Sumit Purohit, Baichuan Zhang, Meg Pirrung, Will Smith, Mathew Thomas
2017 2017 IEEE 33rd International Conference on Data Engineering (ICDE)  
Despite their value, automated construction of knowledge graphs remains an expensive technical challenge that is beyond the reach for most enterprises and academic institutions.  ...  We propose an end-to-end framework for developing custom knowledge graph driven analytics for arbitrary application domains.  ...  The overarching goal of the demonstration will be to show how NOUS can be used to build custom knowledge graphs from web scale data and answer unique domain-specific queries. 1.  ...

Techniques of Ontology and its Usage in Indian Languages - A Review

Rajveer Kaur, Saurabh Sharma
2015 International Journal of Computer Applications  
Ontology is presently an emerging research topic in the field of artificial intelligence, semantic web, and natural language processing, software engineering, and information architecture etc.  ...  It is hereby concluded from the review that in Indian languages usage of ontology is very less because of the challenges to build ontology for minority languages.  ...  This technique of building ontology is concentrated on runtime conversion of implicit knowledge to explicit knowledge, and on raise of knowledge transfer.  ...
