semantic data integration the process of using a conceptual representation of the data and of their relationships to eliminate possible heterogeneities.
Many applications required integration of data from different sources, such as data mining and data / information fusion, etc., and the problem facing any project like this is that data structure different way and the terms and their meanings different from each other, and in this paper we will discuss the most important problems and how solve it using ontology.
Data integration is a perennial challenge facing large-scale data scientists. Bio-ontologies are useful in this endeavour as sources of synonyms and also for rules-based fuzzy integration pipelines.
Concept hierarchy is the backbone of ontology, and the concept hierarchy acquisition has been a hot topic in the field of ontology learning. this paper proposes a hyponymy extraction method of domain ontology concept based on cascaded conditional random field(CCRFs) and hierarchy clustering. It takes free text as extracting object, adopts CCRFs identifying the domain concepts. First the low layer of CCRFs is used to identify simple domain concept, then the results are sent to the high layer, in which the nesting concepts are recognized. Next we adopt hierarchy clustering to identify the hyponymy relation between domain ontology concepts. The experimental results demonstrate the proposed method is efficient.
For efficient and innovative use of big data, it is important to integrate multiple data bases across domains. For example, various public data bases are developed in life science, and how to find a novel scientific result using them is an essential technique. In social and business areas, open data strategies in many countries promote diversity of public data, how to combine big data and open data is a big challenge. That is, diversity of dataset is a problem to be solved for big data.
Ontology gives a systematized knowledge to integrate multiple datasets across domains with semantics of them. Linked Data also provides techniques to interlink datasets based on semantic web technologies. We consider that combinations of ontology and Linked Data based on ontological engineering can contribute to solution of diversity problem in big data.
In this talk, I discuss how ontological engineering could be applied to big data with some trial examples.
Ontology languages are used in modelling the semantics of concepts within a particular domain and the relationships between those concepts. The Semantic Web standard provides a number of modelling languages that differ in their level of expressivity and are organized in a Semantic Web Stack in such a way that each language level builds on the expressivity of the other. There are several problems when one attempts to use independently developed ontologies. When existing ontologies are adapted for new purposes it requires that certain operations are performed on them. These operations are currently performed in a semi-automated manner. This paper seeks to model categorically the syntax and semantics of RDF ontology as a step towards the formalization of ontological operations using category theory.
While the world is witnessing an information revolution unprecedented and great speed in the growth of databases in all aspects. Databases interconnect with their content and schema but use different elements and structures to express the same concepts and relations, which may cause semantic and structural conflicts. This paper proposes a new technique for integration the heterogeneous eXtensible Markup Language (XML) schemas, under the name XDEHD. The returned mediated schema contains all concepts and relations of the sources without duplication. Detailed technique divides into three steps; First, extract all subschemas from the sources by decompose the schemas sources, each subschema contains three levels, these levels are ancestor, root and leaf. Thereafter, second, the technique matches and compares the subschemas and return the related candidate subschemas, semantic closeness function is implemented to measures the degree how similar the concepts of subschemas are modelled in the sources. Finally, create the medicate schema by integration the candidate subschemas, and then obtain the minimal and complete unified schema, association strength function is developed to compute closely of pair in candidate subschema across all data sources, and elements repetition function is employed to calculate how many times each element repeated between the candidate subschema.
Information residing in relational databases and delimited file systems are inadequate for reuse and sharing over the web. These file systems do not adhere to commonly set principles for maintaining data harmony. Due to these reasons, the resources have been suffering from lack of uniformity, heterogeneity as well as redundancy throughout the web. Ontologies have been widely used for solving such type of problems, as they help in extracting knowledge out of any information system. In this article, we focus on extracting concepts and their relations from a set of CSV files. These files are served as individual concepts and grouped into a particular domain, called the domain ontology. Furthermore, this domain ontology is used for capturing CSV data and represented in RDF format retaining links among files or concepts. Datatype and object properties are automatically detected from header fields. This reduces the task of user involvement in generating mapping files. The detail analysis has been performed on Baseball tabular data and the result shows a rich set of semantic information.

The logic-based machine-understandable framework of the Semantic Web often challenges naive users when they try to query ontology-based knowledge bases. Existing research efforts have approached this problem by introducing Natural Language (NL) interfaces to ontologies. These NL interfaces have the ability to construct SPARQL queries based on NL user queries. However, most efforts were restricted to queries expressed in English, and they often benefited from the advancement of English NLP tools. However, little research has been done to support querying the Arabic content on the Semantic Web by using NL queries. This paper presents a domain-independent approach to translate Arabic NL queries to SPARQL by leveraging linguistic analysis. Based on a special consideration on Noun Phrases (NPs), our approach uses a language parser to extract NPs and the relations from Arabic parse trees and match them to the underlying ontology. It then utilizes knowledge in the ontology to group NPs into triple-based representations. A SPARQL query is finally generated by extracting targets and modifiers, and interpreting them into SPARQL. The interpretation of advanced semantic features including negation, conjunctive and disjunctive modifiers is also supported. The approach was evaluated by using two datasets consisting of OWL test data and queries, and the obtained results have confirmed its feasibility to translate Arabic NL queries to SPARQL.
Improve information retrieval and e learning usingIJwest
The Web-based education and E-Learning has become a very important branch of new educational technology. E-learning and Web-based courses offer advantages for learners by making access to resources and learning objects very fast, just-in-time and relevance, at any time or place. Web based Learning Management Systems should focus on how to satisfy the e-learners needs and it may advise a learner with most suitable resources and learning objects. But Because of many limitations using web 2.0 for creating E-learning management system, now-a-days we use Web 3.0 which is known as Semantic web. It is a platform to represent E-learning management system that recovers the limitations of Web 2.0.In this paper we present “improve information retrieval and e-learning using mobile agent based on semantic web technology”. This paper focuses on design and implementation of knowledge-based industrial reusable, interactive, web-based training activities at the sea ports and logistics sector and use e-learning system and semantic web to deliver the learning objects to learners in an interactive, adaptive and flexible manner. We use semantic web and mobile agent to improve Library and courses Search. The architecture presented in this paper is considered an adaptation model that converts from syntactic search to semantic search. We apply the training at Damietta port in Egypt as a real-world case study. we present one of possible applications of mobile agent technology based on semantic web to management of Web Services, this model improve the information retrieval and E-learning system.
USING RELATIONAL MODEL TO STORE OWL ONTOLOGIES AND FACTScsandit
The storing and the processing of OWL instances are important subjects in database modeling.
Many research works have focused on the way of managing OWL instances efficiently. Some
systems store and manage OWL instances using relational models to ensure their persistence.
Nevertheless, several approaches keep only RDF triplets as instances in relational tables
explicitly, and the manner of structuring instances as graph and keeping links between concepts
is not taken into account. In this paper, we propose an architecture that permits relational
tables behave as an OWL model by adapting relational tables to OWL instances and an OWL
hierarchy structure. Therefore, two kinds of tables are used: facts or instances relational tables.
The tables hold instances and the OWL table holds a specification of how the concepts are
structured. Instances tables should conform to OWLtable to be valid. A mechanism of
construction of OWLtable and instances tables is defined in order to enable and enhance
inference and semantic querying of OWL in relational model context.
Translating Ontologies in Real-World SettingsMauro Dragoni
To enable knowledge access across languages, ontologies that are often represented only in English, need to be translated into different languages. The main challenge in translating ontologies is to find the right term with respect to the domain modeled by ontology itself. Machine translation services may help in this task; however, a crucial requirement is to have translations validated by experts before the ontologies are deployed. Real-world applications must implement a support system addressing this task for relieve experts work in validating all translations. In this paper, we present ESSOT, an Expert Supporting System for Ontology Translation. The peculiarity of this system is to exploit semantic information of the concept's context for improving the quality of label translations. The system has been tested both within the Organic.Lingua project by translating the modeled ontology in three languages and on other multilingual ontologies in order to evaluate the effectiveness of the system in other contexts. The results have been compared with the translations provided by the Microsoft Translator API and the improvements demonstrated the viability of the proposed approach.

Towards a Query Rewriting Algorithm Over Proteomics XML ResourcesCSCJournals
Querying and sharing Web proteomics data is not an easy task. Given that, several data sources can be used to answer the same sub-goals in the Global query, it is obvious that we can have many candidates rewritings. The user-query is formulated using Concepts and Properties related to Proteomics research (Domain Ontology). Semantic mappings describe the contents of underlying sources. In this paper, we propose a characterization of query rewriting problem using semantic mappings as an associated hypergraph. Hence, the generation of candidates’ rewritings can be formulated as the discovery of minimal Transversals of an hypergraph. We exploit and adapt algorithms available in Hypergraph Theory to find all candidates rewritings from a query answering problem. Then, in future work, some relevant criteria could help to determine optimal and qualitative rewritings, according to user needs, and sources performances.

An improved technique for ranking semantic associationst07IJwest
The primary focus of the search techniques in the first generation of the Web is accessing relevant
documents from the Web. Though it satisfies user requirements, but it is insufficient as the user sometimes
wishes to access actionable information involvin
g complex relationships between two given entities.
Finding such complex relationships (also known as semantic associations) is especially useful in
applications
such as
National Security, Pharmacy, Business Intelligence etc. Therefore the next frontier is
discovering relevant semantic associations between two entities present in large semantic metadata
repositories. Given two entities, there exist a huge number of semantic associations between two entities.
Hence ranking of these associations is required i
n order to find more relevant associations. For this
Aleman Meza et al. proposed a method involving six metrics viz. context, subsumption, rarity, popularity,
association length and trust. To compute the overall rank of the associations this method compute
s
context, subsumption, rarity and popularity values for each component of the association and for all the
associations. However it is obvious that, many components appears repeatedly in many associations
therefore it is not necessary to compute context, s
ubsumption, rarity
,
popularity
,
and
trust
values of the
components every time for each association rather the previously computed values may be used while
computing the overall rank of the associations. Thi
s paper proposes a method to re
use the previously
computed values using a hash data structure thus reduce the execution time. To demonstrate the
effectiveness of the proposed method, experiments were conducted on SWETO ontology. Results show
that the proposed method is more efficient than the other existi

Open Government Data on the Web - A Semantic ApproachPeter Krantz
(upload with permission from Armand Brahaj)
Initiatives of making governmental data open are continuously gaining interest recently. While this presents immense benefits for increasing transparency, the problem is that the data are frequently offered in heterogeneous formats, missing clear semantics that clarify what the data describes. The data are displayed in ways that are not always clearly understandable to a broad range of user communities that need to make informed decisions.
Association Rule Mining Based Extraction of Semantic Relations Using Markov ...dannyijwest
Ontology may be a conceptualization of a website into a human understandable, however machine-
readable format consisting of entities, attributes, relationships and axioms. Ontologies formalize the
intentional aspects of a site, whereas the denotative part is provided by a mental object that contains
assertions about instances of concepts and relations. Semantic relation it might be potential to extract the
whole family-tree of a outstanding personality employing a resource like Wikipedia. In a way, relations
describe the linguistics relationships among the entities involve that is beneficial for a higher
understanding of human language. The relation can be identified from the result of concept hierarchy
extraction. The existing ontology learning process only produces the result of concept hierarchy extraction.
It does not produce the semantic relation between the concepts. Here, we have to do the process of
constructing the predicates and also first order logic formula. Here, also find the inference and learning
weights using Markov Logic Network. To improve the relation of every input and also improve the relation
between the contents we have to propose the concept of ARSRE.

ONTOLOGY SERVICE CENTER: A DATAHUB FOR ONTOLOGY APPLICATIONIJwest
With the growth of data-oriented research in humanities, a large number of research datasets have been
created and published through web services. However, how to discover, integrate and reuse these distributed
heterogeneous research datasets is a challenging task. Ontology is the soul between series digital humanities
resources, which provides a good way for people to discover and understand these datasets. With the release
of more and more linked open data and knowledge bases, a large number of ontologies have been produced
at the same time. These ontologies have different publishing formats, consumption patterns, and interactions
ways, which are not conductive to the user’s understanding of the datasets and the reuse of the ontologies.
The Ontology Service Center platform consists of Ontology Query Center and Ontology Validation Center,
mainly using linked data and ontology-based technologies. The Ontology Query Center realizes the functions
of ontology publishing, querying, data interaction and online browsing, while the Ontology Validation
Center can verify the status of using certain ontologies in the linked datasets. The empirical part of the paper
uses the Confucius portrait as an example of how OSC can be used in the semantic annotation of images. In
a word, the purpose of this paper is to construct the applied ecology of ontology to promote the development
of knowledge graphs and the spread of ontology.

A Survey On Ontology Agent Based Distributed Data MiningEditor IJMTER
With the increased complexity in number of applications and due to large volume

suitable ontology, which can handle the large data set and present the mined outcomes for

effectiveness of modern agent-based systems for distributed data mining
Concept integration using edit distance and n gram match ijdms
Information is growing more rapidly on the World Wide Web (WWW) has made it necessary to make all
this information not only available to people but also to the machines. Ontology and token are widely being
used to add the semantics in data processing or information processing. A concept formally refers to the
meaning of the specification which is encoded in a logic-based language, explicit means concepts,
properties that specification is machine readable and also a conceptualization model how people think
about things of a particular subject area. In modern scenario more ontologies has been developed on
various different topics, results in an increased heterogeneity of entities among the ontologies. The concept
integration becomes vital over last decade and a tool to minimize heterogeneity and empower the data
processing. There are various techniques to integrate the concepts from different input sources, based on
the semantic or syntactic match values. In this paper, an approach is proposed to integrate concept
(Ontologies or Tokens) using edit distance or n-gram match values between pair of concept and concept
frequency is used to dominate the integration process. The proposed techniques performance is compared
with semantic similarity based integration techniques on quality parameters like Recall, Precision, FMeasure
& integration efficiency over the different size of concepts. The analysis indicates that edit
distance value based interaction outperformed n-gram integration and semantic similarity techniques.

Ontologies are being used to organize information in many domains like artificial intelligence,
information science, semantic web, library science. Ontologies of an entity having different information
can be merged to create more knowledge of that particular entity. Ontologies today are powering more
accurate search and retrieval in websites like Wikipedia etc. As we move towards the future to Web 3.0,
also termed as the semantic web, ontologies will play a more important role.
Ontologies are represented in various forms like RDF, RDFS, XML, OWL etc. Querying ontologies can
yield basic information about an entity. This paper proposes an automated method for ontology creation,
using concepts from NLP (Natural Language Processing), Information Retrieval and Machine Learning.
Concepts drawn from these domains help in designing more accurate ontologies represented using the
XML format. This paper uses document classification using classification algorithms for assigning labels
to documents, document similarity to cluster similar documents to the input document, together, and
summarization to shorten the text and keep important terms essential in making the ontology. The module
is constructed using the Python programming language and NLTK (Natural Language Toolkit). The
ontologies created in XML will convey to a lay person the definition of the important term's and their
lexical relationships.

This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Ontology For Data Integration
1. Some Thoughts Juan Esteva, Ph. D. . 751 Malena Dr., Ann Arbor, MI 48103 Tel: 734-786-0233 Cell 734-277-4962 Fax 734-821-0235 SkypeDrEsteva juan.esteva@Ajatella.com Ontology Data Integration For Competitive Decision Making
2. Not Just The Facts 3/4/2010 Juan Esteva, Ph. D. 2 “Good decisions are based on information that is analyzed and transformed into usable knowledge” Eileen Feretic
3. Information at the point of impact 3/4/2010 Juan Esteva, Ph. D. 3 “Information needs to be at the point of impact—at the front lines where people are making decisions. The right analysis needs to be done at the right place. It’s important for organizations to treat information as a strategic asset in order to optimize every decision, every process, everything they do.” AmbujGoyal,
4. Data in Silos 3/4/2010 Juan Esteva, Ph. D. 4 “One of the biggest challenges organizations face is the amount of data sitting in silos, too often, valuable data simply isn’t accessible or available.” Boris Evelson
5. Business Decisions for Competitive Advantage 3/4/2010 Juan Esteva, Ph. D. 5 “In today’s troubled economy and competitive business environment, making good decisions is a matter of survival. But good decisions aren’t based on gut feeling alone. They should be based on information gathered from multiple sources, which is then synthesized and analyzed to generate a road map of options and possible outcomes that transform data into usable knowledge” Eileen Feretic
6. Business Intelligence 3/4/2010 Juan Esteva, Ph. D. 6 Business Intelligence and now Business Analytics systems come into play [However,] it is hard to assemble [heterogeneous data and] disparate pieces of information in a way that provides the intelligence and insight needed to make good business decisions. Eileen Feretic Alas enter Ontology Data Integration.
7. Data Integration 3/4/2010 Juan Esteva, Ph. D. 7 Data integration provides the ability to manipulate data transparently across multiple data sources. Based on the architecture there are 2 systems: Central Data Integration A central data integration system usually has a global schema, which provides the user with a uniform interface to access information stored in the data sources Peer-2-peer In contrast, in a peer-to-peer data integration system, there are no global points of control on the data sources (or peers). Instead, any peer can accept user queries for the information distributed in the whole system.
8. Common Approaches for Data Integration 3/4/2010 Juan Esteva, Ph. D. 8 Global-as-View In the GaV approach, every entity in the global schema is associated with a view over the source local schema. Therefore querying strategies are simple, but the evolution of the local source schemas is not easily supported. Local-as-View On the contrary, the LaV approach permits changes to source schemas without affecting the global schema, since the local schemas are defined as views over the global schema, but query processing can be complex.
9. Data Heterogeneity 3/4/2010 Juan Esteva, Ph. D. 9 Data sources can be heterogeneous in: Syntax Syntactic heterogeneity is caused by the use of different models or languages. Schema Schematic heterogeneity results from structural differences. Semantics Semantic heterogeneity is caused by different meanings or interpretations of data in various contexts To achieve data interoperability, the issues posed by data heterogeneity need to be eliminated
10. Possible Solutions 3/4/2010 Juan Esteva, Ph. D. 10 The advent of XML has created a syntactic platform for Web data standardization and exchange. However, schematic data heterogeneity may persist, depending on the XML schemas used (e.g., nesting hierarchies). Likewise, semantic heterogeneity may persist even if both syntactic and schematic heterogeneities do not occur (e.g., naming concepts differently). We should be concerned with solving all three kinds of heterogeneities by bridging syntactic, schematic, and semantic heterogeneities across different sources.
11. Semantic Data Integration Using Ontologies 3/4/2010 Juan Esteva, Ph. D. 11 We call semantic data integration the process of using a conceptual representation of the data and of their relationships to eliminate possible heterogeneities. At the heart of semantic data integration is the concept of ontology, which is an explicit specification of a shared conceptualization
12. Ontology & Data Integration 3/4/2010 Juan Esteva, Ph. D. 12 Metadata Representation. Metadata (i.e., source schemas) in each data source can be explicitly represented by a local ontology, using a single language. Global Conceptualization. The global ontology provides a conceptual view over the schematically-heterogeneous source schemas. Support for High-level Queries. Given a high-level view of the sources, as provided by a global ontology, the user can formulate a query without specific knowledge of the different data sources. The query is then rewritten into queries over the sources, based on the semantic mappings between the global and local ontologies. Declarative Mediation. Query processing in a hybrid peer-to-peer system uses the global ontology as a declarative mediator for query rewriting between peers. Mapping Support. A thesaurus, formalized in terms of an ontology, can be used for the mapping process to facilitate its automation.
13. What do we need? 3/4/2010 Juan Esteva, Ph. D. 13 Increase search capabilities From discovery to reasoning Increasing metadata as to provide strong semantics From glossaries to ontologies Consequently, moving from syntactic interoperability to structural interoperability and finally to semantic interoperability
14. Graphically the model progression will be [2] 3/4/2010 Juan Esteva, Ph. D. 14 The point of this graph is that Increasing Metadata (from glossaries to ontologies) is highly correlated with Increasing Search Capability (from discovery to reasoning).

17. Topic Maps 3/4/2010 Juan Esteva, Ph. D. 17 Topic Maps is a standard for the representation and interchange of knowledge, with an emphasis on the findability of information. The ISO standard is formally known as ISO/IEC 13250:2003. A topic map represents information using topics (representing any concept, from people, countries, and organizations to software modules, individual files, and events), associations (representing the relationships between topics), and occurrences (representing information resources relevant to a particular topic).
18. SKOS 3/4/2010 Juan Esteva, Ph. D. 18 Simple Knowledge Organization System (SKOS) SKOS is a common data model for sharing and linking knowledge organization systems via the Web.
19. RDF 3/4/2010 Juan Esteva, Ph. D. 19 Resource Description Language RDF RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed.
20. OWL 3/4/2010 Juan Esteva, Ph. D. 20 Web Ontology Language OWL is a Semantic Web language designed to represent rich and complex knowledge about things, groups of things, and relations between things. OWL is a computational logic-based language such that knowledge expressed in OWL can be reasoned with by computer programs either to verify the consistency of that knowledge or to make implicit knowledge explicit. OWL documents, known as ontologies, can be published in the World Wide Web and may refer to or be referred from other OWL ontologies. OWL is part of the W3C’s Semantic Web technology stack, which includes RDF, RDFS, SPARQL, etc.
